                  Preliminary Results for FY 2022 (unaudited) 
 
       Record results and a significant turnaround in Petra's net debt 
 
Petra announces its preliminary results (unaudited) for the year ended 30 June 
2022 (Year or FY 2022). Separate announcement on the 2026 Loan Notes Tender 
offer issued today. 
 
Financial highlights 
 
  * Revenue up 44% to US$585 million 
  * Doubling of adjusted EBITDA to US$265 million 
  * Adjusted basic earnings per share up 219% to USc42.93 
  * Operational free cash flow up 91% to US$230 million 
  * Consolidated net debt of US$40.6 million, with leverage of 0.15x 
 
Enabling 
 
  * Launch of US$150 million tender offer to reduce gross debt 
  * Announcement of dividend policy 
 
Richard Duffy, Chief Executive Officer of Petra, commented: 
 
"We are delighted with our overall performance, which caps the turnaround begun 
three years ago. Our continued focus on safety has supported a 48% improvement 
in our LTIFR. Additionally, sustainability is being integrated across our 
business through the implementation of our new Sustainability Framework. 
Project 2022, now concluded, has delivered US$265 million in net free cash over 
its three years, contributing to our record financial results for FY2022. 
 
In addition to Project 2022, the key drivers were our record recovery of 
Exceptional Stones[1], the resumption of operations at the Williamson mine, and 
a 41.5% increase in like-for-like[2] diamond prices. The diamond market remains 
broadly supportive as a result of the prevailing structural supply deficit, 
although ongoing macro-economic uncertainties may lead to some volatility in 
the short term. 
 
Our strong cash generation in FY 2022 has enabled us to target a further 
reduction in our gross debt through a tender offer for US$150 million of our 
2nd lien notes, detailed in a separate release today. This will see us saving 
up to US$15 million annually in interest expenses. 
 
I am also very pleased to announce that, on the back of our much improved 
financial position, the Board has approved a dividend policy."

Note 1: For all non-GAAP measures refer to the Summary of Results table within 
the Financial Results section below. 
 
Note 2: For comparative purposes, the FY 2021 income statement figures include 
Williamson as it is no longer a discontinued operation - refer to note 2. 
Consolidated net debt and cash balances for FY 2021 have not been adjusted. 
 
Note 3: The comparative basic profit per share and adjusted profit per share 
have been adjusted to give effect to the share consolidation of one new share 
for every 50 existing shares completed on 29 November 2021 with the Company's 
resultant issued share capital now consisting of 194,201,785 ordinary shares of 
0.05 pence each. 
 
  * FY 2022 total revenue of US$585.2 million comprises revenue from rough 
    diamond sales of US$584.1 million and additional revenue from profit share 
    agreements on partnership stones of US$1.1 million. The 44% increase in 
    revenue from rough diamond sales was driven by: 
      + A 41.5% increase in year-on-year like-for-like prices 
      + The contribution from the sale of a record number of Exceptional Stones 
        of US$89.1 million; this compares with an average of US$39.2 million 
        over the last five years 
 
  * Adjusted EBITDA rose 103% to US$264.9 million, reflecting the positive 
    operational leverage from our revenue growth, as well as improved 
    efficiencies from Project 2022; Adjusted EBITDA margin rose to 45% 
  * Adjusted net profit after tax rose to US$102.0 million (reversing a US$25.5 
    million adjusted net loss after tax last year). Net profit after tax fell 
    55% to US$88.1 million largely driven by a prior year gain of US$213.3 
    million on the extinguishing of the Notes  as part of the Group's capital 
    restructuring, and unrealised foreign exchange losses of US$34.3 million 
    net of tax (FY 2021 unrealised gain of US$54.7 million net of tax) 
  * Adjusted basic earnings per share was USc42.93 up 219% 
  * Operational free cash flow rose 91% to US$230.0 million driven by increased 
    EBITDA 
  * Consolidated net debt reduced 82% to US$40.6 million which is 0.15x EBITDA, 
    reflecting this strong free cash flow generation

  * LTIFR improved 48% to 0.23, and LTIs improved 40% to 15 including an LTI 
    which occurred during FY 2022 but was recorded post year-end 
  * Production increased 3% to 3,353,670 carats, largely owing to the 
    resumption of mining at Williamson 
  * Cash-on-mine costs remained within guidance despite inflationary pressures 
  * Capital expenditure, which comprises expansion and sustaining capex, was 
    below guidance largely attributable to expenditure of around US$12 million 
    being deferred from FY 2022 to FY 2023 
  * Our new Sustainability Framework is being fully integrated into Petra's 
    operating model.  Sustainability targets will be detailed in the FY 2022 
    Sustainability Report in October 
  * Petra is targeting zero greenhouse gasses (GHG) emissions on a net basis by 
    2050. This commitment includes an aspirational goal to reach net-zero 
    emissions for Scope 1 and 2 GHG by 2040 or earlier. Additional details will 
    be provided in the Annual Report and Sustainability Report in October

Petra reaffirms its operational guidance provided for the FY 2023 to FY 2025 
period, noting the following: 
 
  * While Cullinan Mine recorded lower grades towards the end of the Year, a 
    study is underway to inform our mine planning as a result of a higher 
    proportion of ROM tonnes from our more mature drawpoints 
  * The impact of waste dilution on grades experienced at Finsch in Q4 FY2022 
    has continued into Q1 of this year, with ongoing monitoring and mitigation 
    plans to address this 
  * Options for a responsible exit at Koffiefontein, including the evaluation 
    of non-binding expressions of interest. 
 
New dividend policy 
 
The Board approved a dividend policy targeting an ordinary dividend within the 
range of 15% to 35% of  adjusted free cash flows after interest and tax and 
having adjusted for any windfall earnings. 
 
The Board would ordinarily look to the annual dividend being paid 1/3 following 
its interim results and 2/3 after its full year results. The dividend policy 
will take effect from 1 July 2022 and the Board will consider whether to pay a 
maiden dividend under this policy following publication of Petra's interim 
results for the six months ending 31 December 2022. In a year where Petra 
generates windfall earnings, the Board may consider paying a special dividend. 
 
Prior to declaring or recommending any dividend, the Board will consider the 
Group's capital commitments, including, amongst other things, approved 
expansion projects and debt servicing and repayment commitments and associated 
covenant requirements, to ensure that the Group maintains a healthy balance 
sheet and sufficient liquidity and headroom. 
 
Debt tender offer 
 
Petra today also announced its intention to reduce its gross debt through a 
tender offer to bondholders to purchase US$150 million of the Senior Secured 
Second Lien Notes due in 2026 in line with our stated intent to further 
optimise our capital structure through a reduction of gross debt.  If 
completed, the transaction will see Petra saving up to US$15 million per annum 
in interest expenses, while we remain confident that we will continue to fund 
our ongoing capital programmes from existing and internally generated cash 
resources. Further detail on the tender offer is covered in a separate 
announcement which can be found on Petra's website at https:// 
www.petradiamonds.com/investors/news/ 
 
Outlook 
 
FY2023 - 2025 production, cost and capex guidance remains unchanged. We 
continue to monitor the evolving macro-economic environment that has seen 
higher inflation and interest rates. Our ability to absorb inflationary 
pressures is assisted by our disciplined cost management, relatively low fuel 
consumption, and any weakening of the South African Rand. 
 
The backdrop of structural changes to the supply and demand fundamentals in the 
diamond market remains unchanged and we anticipate that it will continue to be 
supportive going forward, notwithstanding possible volatility in the short 
term. 
 
The implementation of our new operating model, that formed part of Project 
2022, has provided a more stable and resilient operating platform supporting 
ongoing cash generation, enabling our self-funded expansion programme, the 
US$150 million tender offer for our 2nd lien notes and the potential payment of 
dividends under our new dividend policy.

Consolidated net debt and cash balances for FY 2021 have not been adjusted. 
 
Overall revenue increased 44% to US$585.2 million, comprising US$584.1 million 
from rough diamond sales and an additional US$1.1 million from our first 
partnership stone sale. The drivers of this revenue growth were the 
year-on-year 41.5% increase in like-for-like diamond prices and record recovery 
and sale of Exceptional Stones, totalling US$89.1 million (FY 2021: US$62.0 
million). 
 
The 11% reduction in rough diamonds sold reflects the particularly high volumes 
sold in FY 2021, mostly off-tender, as the inventory build-up after the initial 
COVID-19 outbreak was released. 
 
Adjusted EBITDA rose 103% to US$264.9 million with an Adjusted EBITDA margin of 
45% reflecting the strong revenue growth and positive operational leverage, 
supported by the recovery of Exceptional Stones. 
 
The 91% improvement in operating free cash flow generation has been supported 
by the Project 2022 initiatives. Over the three years since its commencement 
the Project has contributed US$265.4 million of net free cash flow benefits, 
exceeding our revised target of delivering net free cash flow of between US$100 
million and US$150 million. 
 
This cash generation means that we lowered our consolidated net debt to US$40.6 
million as at 30 June 2022, down from US$228.2 million as at 30 June 2021.

Note1: For comparative purposes, the FY 21 production and cost figures have 
been restated to include Williamson as it is no longer a discontinued operation 
 
We strive to achieve a zero-harm working environment.  Petra has focused on 
improving safety performance through remedial actions and behaviour-based 
intervention programmes. As a result, we have improved the Lost Time Injury 
Frequency Rate (LTIFR) by 48% to pre-pandemic levels, and Lost Time Injuries 
(LTIs) by 40% which were of low severity and mostly behavioural in nature. We 
continue the roll-out of COVID-19 vaccinations for employees and 64% of the 
workforce in South Africa and 15% of the workforce in Tanzania have been 
vaccinated. The vaccination rate in South Africa is well ahead of the national 
average of 51%. 
 
The vast majority of the 44% increase in ore processed is attributable to 
Williamson recommencing operations in August 2021 following a 17-month period 
of care and maintenance. Williamson ore is lower grade in comparison to our 
South African mines and this translated into a 3% increase in diamonds 
recovered, within our guidance range. 
 
Project 2022 has, as part of the focus on cash generation, been highly 
effective in addressing both operational efficiencies as well as the efficiency 
of our operational and capital expenditure. We have created a Business 
Improvement function to ensure that the systems and processes developed as part 
of Project 2022, which concluded this Year, will continue to deliver benefits 
and seek out further improvement opportunities. Supporting this culture of 
continuous improvement, our new operating model has clarified lines of 
accountability and further empowers our people. 
 
Cash on-mine costs and G&A costs were in line with guidance. The 11% increase 
in adjusted mining and processing costs was principally due to the resumption 
of operations at Williamson during the first quarter of the Year, the stronger 
average ZAR/USD exchange rate and inflationary increases. 
 
Group capex of US$52.2 million was below guidance following delayed delivery of 
certain capital items planned for FY 2022 due to increased lead-times. As a 
result, around US$12 million of capex that was due to be incurred in FY 2022 is 
now expected to be incurred in FY 2023. US$34.5 million of the FY 2022 capital 
spend was expansionary capex and the vast majority of total capex was invested 
at the Cullinan and Finsch Mines (US$35.0 million and US$12.0 million 
respectively). 
 
Load shedding and energy reform in South Africa 
 
The recent increase in load shedding in South Africa is currently having 
minimal impact on our operations. Our excess processing capacity at both 
Cullinan Mine and Finsch allows us to reduce our processing energy draw to meet 
the prescribed load curtailment requirements whilst maintaining mining at full 
production and catching up on processing when conditions return to normal. 
 
The regulator in South Africa has increased the allowance for self-generation 
without requiring a generation licence to a maximum of 100 MW. This has opened 
up opportunities for high energy-users to integrate renewables on their own 
sites and Petra is actively looking at options that are optimal from a 
financing and partnering perspective that would enable us to integrate 
renewables into our energy mix, lower our cost of energy, secure our energy 
supply and support our target of achieving net zero GHG emissions by 2050 or 
earlier. 
 
Extending our mine plans 
 
Resources 
 
Petra manages one of the world's largest gross diamond resources (inclusive of 
reserves) of 226.6 Mcts, supporting a  potential mine life well beyond the 
current mine plans. The 2% reduction compared to 230.64 Mcts in 30 June 2021, 
was predominantly due to depletions resulting from mining at all our assets in 
FY 2022. 
 
Petra's gross diamond reserves decreased 10% to 29.97 Mcts (30 June 2021: 33.33 
Mcts) primarily due to mining depletions with minor changes in mine plans and 
Williamson remaining on care and maintenance until August 2021. 
 
Life extension projects approved during the Year 
 
As announced previously, the Board approved extension projects at our major 
South African mines, the Cullinan and Finsch Mines, during the Year. 
 
  * At the Cullinan Mine we will establish a CC1 East sub-level cave, on the 
    same level as the current C-Cut operation, extending the mine plan to 2031. 
    The capital investment is estimated at US$173 million over the life of the 
    project and is expected to deliver a project internal rate of return (IRR) 
    of more than 30% and incremental project NPV of more than US$70 million. 
    Capital expenditure began during the Year and production is expected to 
    begin in FY 2024, ramping up to a steady state in FY 2026. 
 
  * At Finsch, we will extend the mine below the current area, creating a Lower 
    Block 5 3-level sub-level cave, extending the mine plan to 2030. The 
    capital investment is estimated at US$216 million and the IRR is also 
    expected to be in excess of 30% with incremental NPV of more than US$90 
    million. Capital expenditure for this project will commence during FY 2023 
    and we expect production to commence in FY 2025. 
  * The capex involved in these projects is expected to be self-funded. 
 
There are further opportunities beyond these mine extension plans, given the 
significant scale of the orebodies at the Cullinan, Williamson and Finsch 
Mines. 
 
Diamond market remains buoyant despite uncertainties 
 
Despite significant global economic uncertainties resulting from the war in 
Ukraine, like-for-like rough diamond prices increased 41.5% for the Year, 
driven in particular by record jewellery retail demand in the US. Overall we 
saw strength of demand across our product mix, both in white and coloured 
gem-quality stones, with some increased demand for smaller diamonds in the 
final tender of the Year in June. 
 
Tender 1 FY 2023, announced today 
 
We have achieved strong sales in the first tender of FY 2023, realising 
US$102.9 million due to a high proportion of high-value gem-quality single 
stones particularly from the Cullinan Mine. This has resulted in a 21% increase 
in our average realised price against Tender 6 in FY 2022, more than offsetting 
the 4.5% softening of like-for-like prices. 
 
The supportive structural supply deficit in the diamond market 
 
Growth in demand was driven by mid-stream inventory restocking and continued 
strong jewellery retail sales associated with a delayed wedding boom and a 
growing trend in diamonds being given as meaningful gifts post COVID-19. While 
the diamond market is strong, macroeconomic uncertainties caused by the rise in 
inflation are a potential dampener of demand. 
 
Global supply is expected to remain broadly flat for the next ten years at 
between 115 and 125 Mcts. This is driven by the reduction in the number of 
producing mines, the long lead-times for open-pit mines to transition to 
underground mining, as well as the very limited investment in exploration. 
Given that less than 1% of kimberlites discovered are economic, we do not 
expect this to change in the medium term.

Note 1: FY 21 metrics are affected by Williamson being on care and maintenance 
 
The comparability of FY 2022 and FY 2021 performance is distorted by the 
resumption of the open-pit operations at Williamson in August 2021. 
 
Petra is embedding its new Sustainability Framework so that environmental, 
social and governance improvements are further integrated throughout our 
operations. Targets will be published in our FY 2022 Sustainability Report in 
October. 
 
Petra remains committed to reducing our GHG profile and to generate zero 
emissions on a net basis for Scopes 1 and 2 (emissions from sources we own and 
control directly and those through the energy we purchase) by 2050, although we 
aspire to reach this goal by 2040 or earlier. Our emissions profile is heavily 
weighted to our Scope 2 emissions which comprise 97% of total emissions in 
South Africa, and 92% including Tanzania. We will announce targets for 2030 in 
the FY 2022 Annual and Sustainability Reports to be published in October. Our 
Scope 3 reductions will be pursued once our Scope 1 and 2 roadmap has been 
developed. Our Climate Change Adaptation Strategy is being updated in 
accordance with TCFD requirements. 
 
Framework Agreement with the Government of Tanzania and MOU with Caspian 
 
In December 2021, Petra announced that it had entered into two agreements with 
the objective of reducing its exposure to Tanzania while still retaining 
control of Williamson. 
 
The Framework Agreement between Petra and the Government of Tanzania will 
become effective after a number of conditions are satisfied, including 
obtaining various government approvals. The agreement, which will result in the 
reduction of Petra's indirect shareholding in Williamson Diamonds Limited (WDL) 
from 75% to 63% and establish a sustainable future for Williamson, is 
progressing and is now expected to become effective in the first half of FY 
2023. 
 
Petra expects to further reduce its indirect shareholding in WDL from 63% to 
31.5% via a sale to Caspian Limited but with Petra retaining a controlling 
interest in WDL as Petra have the controlling vote on the WDL Board via its 
controlling interest in the intermediate holding company. The transaction 
remains subject to the parties first agreeing definitive transaction agreements 
and then obtaining all necessary government, regulatory and lender approvals 
which are also expected to be obtained in the first half of FY 2023. 
 
Independent Grievance Mechanism and community projects at Williamson 
 
Petra has implemented remedial programmes and initiatives and is establishing 
the Independent Grievance Mechanism (IGM) to address the historical allegations 
of human rights abuses at Williamson. The second phase of engagements with the 
Government of Tanzania and local stakeholders on the IGM has been completed and 
the focus is now on updating the IGM processes and appointing the various 
organs that will make up the IGM, with the current target for the IGM to become 
operational remaining Q4 of CY 2022. 
 
While the IGM is still being finalised, a mechanism has been set up to enable 
community members to confidentially and securely register alleged historical 
human rights grievances. This mechanism continues to receive grievances, with a 
significant amount of grievances having been registered to date. As the IGM is 
not yet operational (and therefore unable to start investigating these 
grievances), it is too early to evaluate the merits of these grievances. 
 
A number of other initiatives are being put in place to provide sustainable 
benefits to the communities located close to the mine, funded by the £1 million 
Escrow account established by Petra. Having completed all planned activities in 
Q1 CY 2022, the Gender Based Violence initiative is now training young men as 
champions and first responders and setting up survivor self-help groups within 
the surrounding communities. The medical services project has been expanded to 
provide further services, including surgery, medication and psychological 
support. Feasibility studies for income generating projects (agriculture 
businesses and artisanal mining) are also progressing and a radio programme to 
improve awareness and understanding of the IGM and community projects amongst 
the local community has been set up. 
 
More information on the IGM, the community projects and illegal incursions into 
the Williamson mine lease area can be found on Petra's website at: https://

The Board 
 
As previously announced, Jon Dudas joined the Board as an independent 
Non-Executive Director effective from 1 March 2022, further strengthening the 
Board through his broad experience across the mining and resources sectors, in 
operations, general management, information technology, finance and strategy. 
 
Also, as previously announced, Matthew Glowasky stepped down from the Board as 
a non-independent, Non-Executive Director on 17 May. His appointment became 
effective in March 2021, following completion of the Restructuring pursuant to 
a Nomination Agreement between Petra and Monarch. While Monarch does not 
currently intend to nominate a director to replace Mr Glowasky, it retains its 
right to do so.

 1. Petra is not able to precisely measure the ROM / tailings grade split 
    because ore from both sources is processed through the same plant; the 
    Company therefore back-calculates the grade with reference to resource 
    grades 
 2. The segment result includes depreciation of US$52.5 million 
 
At the Cullinan Mine we came in at the upper end of our production guidance 
ranges on all criteria except tailings. Diamonds produced were 7% below last 
year's, largely as a result of the convergence in Tunnel 41 early in the Year, 
and the planned depletion of a mining block which had contributed to production 
in FY 2021. The convergence has now been effectively mitigated and factored 
into our guidance. 
 
The Cullinan Mine's revenue increased 29% to US$322.4 million due to a 52% 
increase in the average price achieved per carat and the US$75.2 million 
realised for Exceptional Stones. Together, these more than offset the 16% 
reduction in diamonds sold, which was mainly the result of a higher volume of 
sales in FY 2021 caused by the release of the inventory build-up during the 
COVID-19 crisis into the market. Additional revenue of US$1.1 million was 
generated from Petra's 50% share of profit from the sale of polished stones cut 
from the 18.30ct Type II blue diamond sold as a partnership stone in August 
2021. 
 
The convergence of Tunnel 41 in the C-Cut impacted 18 of a total of 187 draw 
points. Remedial action was focused on arresting convergence by reinforcing the 
affected pillars and protecting the tunnel, so that access can be 
re-established once the area has been stabilised. We continue to monitor it to 
determine when we will be able to re-access this tunnel. 
 
Grade was in line with guidance, notwithstanding the decline towards the end of 
the Year due to a change in the composition of ore within the C-Cut block cave 
resulting in a higher proportion of lower-grade and greater-density ore. We are 
monitoring these changes together with options to mitigate the grade 
differential. 
 
During the Year, the efficiency of the X-Ray Luminescence technology (XRL), 
introduced in FY 2021, to reduce the risk of damage to larger stones in our 
processing circuit, was tested through the addition of a modular X-Ray 
Transmission (XRT) unit. This unit recovered only 11 additional diamonds of low 
value, validating the decision to use XRL technology in the recovery process. 
 
The on-mine unit cash cost per total tonne treated increased to ZAR312/t due to 
inflationary increases, increased social expenditure and direct costs 
previously included under Group G&A costs. FY 2022 capex was US$35.0 million, 
the majority of which was spent on the commencement of the newly approved CC1 
East mine extension project. The balance included spend on the projects already 
underway in the current mining area, development of a crusher, and improved 
long-term accessibility in an area of the C-Cut. 
 
Guidance 
 
FY 2023 to FY 2025 production, cost and capex guidance for the Cullinan Mine 
remain unchanged. 
 
  * Our production guidance for FY 2023 is between 4.1 and 4.3 Mt ROM material 
    to be treated, and ROM grade of between 36.5 and 38.5cpht, including the 
    ore from the portions of the current mining area, the C-Cut, that is lower 
    grade and higher in density. 
  * Tailings production is expected to increase to between 0.56 and 0.59 Mt 
    material treated.  ROM production will be prioritised, supplemented by low 
    volumes of recovery tailings. The economic evaluation of the Cullinan 
    Mine's substantial tailings resource will be monitored continuously and 
    could be included in future mine plans dependent on market conditions and 
    the pricing of smaller diamonds. 
  * The on-mine cash cost for FY 2023 guidance is between ZAR1,413 and ZAR1,486 
    million in real terms. 
  * We are guiding FY 2023 capex of between US$72 and US$79 million. In 
    addition to sustaining capex, it primarily relates to underground 
    development of the new CC1 East production areas of our extension project, 
    explained above. 
  * We expect to commence mining from the higher grade CC1 East section from FY 
    2024.

While the previously reported waste ingress at Finsch has been largely 
mitigated through the implementation of enhanced drill and blast and draw 
controls, this requires continuous management. 
 
We saw steady production in the final quarter of the Year leading to an overall 
increase of 3%, just below guidance. 
 
Finsch revenue increased 34% to US$165.7 million due to a 53% increase in the 
average price per carat which more than offset a 12% reduction in diamonds 
sold. As with the Cullinan Mine, this reduction was mainly the result of a 
higher volume of sales in FY 2021 which was caused by the inventory build-up 
during the COVID-19 pandemic being released into the market. 
 
The Business Re-engineering (BRE) project recommendations being implemented at 
Finsch are designed to match its cost base to the revised production levels, 
taking into account waste ingress issues. 
 
Finsch has already reduced on-mine cash unit costs by 8% to ZAR493/t due to the 
cost curtailment measures undertaken as part of the BRE project and increased 
production volumes. 
 
FY 2022 capex was US$12.0 million which was mainly spent on underground 
projects. The expansion to the new 78 Level Phase 2 project has commenced, with 
ramp-up to full production in progress. In addition, capital has been spent on 
early mobilisation to de-risk the new Lower Block 5 3-Level sub-level cave 
project. 
 
Guidance 
 
FY 2023 to FY 2025 production, cost and capex guidance for Finsch remain 
unchanged , although 
 
lower grades experienced at Finsch in Q4 FY 2022 have continued into Q1 of this 
year, with ongoing monitoring and mitigation plans to address this waste 
dilution.  We will continue to implement the BRE project recommendations to 
align costs with production. 
 
  * FY 2023 production is planned at between 2.9 and 3.0 Mt ROM including 
    tonnage from the new section and with waste ingress being continually 
    monitored. Tailings production is expected to be c.0.6 Mt of treated 
    material. 
  * Finsch's underground ROM grade is expected to remain within guidance of 
    between 43.6 and 46.0 cpht. While tailings production after FY 2023 does 
    not form part of the current mine plan, lower grade tailings material 
    remains available to supplement Finsch's underground operations in the 
    future. The total on-mine cash cost for FY 2023 is guided at between 
    ZAR1,293 and ZAR1,359 million in real terms. We are continuing to implement 
    the BRE project outcomes to enhance margins at Finsch. 
  * FY 2023 capex is guided at between US$65 and US$71 million, primarily 
    relating to the new Lower Block 5 3-Level sub-level cave project which was 
    approved during the Year. 
  * We expect underground development to commence during FY 2023 with 
    production from the new Sub-Level Cave in FY 2025.

Operations at Williamson recommenced in August 2021, having been on care and 
maintenance from April 2020. FY 2022 was a year of improving the performance of 
the mine after this 17-month period of shutdown and the operations are now 
fully ramped up. 
 
Williamson's production and grade were in line with guidance. Revenue was 
US$75.9 million, compared with US$4.6 million in FY 2021 when the only diamond 
sales were the final parcel recovered prior to the mine being placed on care 
and maintenance. We benefitted from the recovery of an exceptional 32.32 carat 
pink diamond which was sold for US$13.8 million in the December 2021 tender. 
 
The on-mine cash unit cost of US$13.9/t was in line with guidance. FY 2022 
capex was US$3.3 million, which included the costs of preparing the mine for 
reopening and sustaining the operations. 
 
Guidance 
 
The focus will be the continued stabilisation of operations following the 
period of care and maintenance, including increasing throughput and diamond 
recovery, while ensuring waste-stripping is undertaken at the required rate. 
 
FY 2023 to FY 2025 production, cost and capex guidance remain unchanged for 
Williamson. 
 
  * We are guiding between 5.2 and 5.5 Mt of ROM material to be treated during 
    FY 2023 which reflects the fully ramped up production. 
  * The total on-mine cash cost for FY 2023 is guided at between US$66 and 
    US$69 million in real terms. 
  * Capex guidance for FY 2023 is approximately US$9 million and relates to 
    sustaining capital largely associated with waste stripping and 
    fines-residue infrastructure.

Koffiefontein's production metrics, except grade, were below guidance. Revenue 
decreased 23% to US$21.5 million as the 39% increase in the average price per 
carat was more than offset by the 45% decline in the number of diamonds sold. 
 
As Koffiefontein approaches the end of its mine plan in 2025, Petra is 
exploring options for a responsible exit. We are evaluating non-binding 
expressions of interest, received post year-end for the mine. If a sales 
transaction does not eventuate, Petra will evaluate its options and continue to 
operate the mine responsibly. 
 
The BRE project at Koffiefontein, which is independent of the disposal process, 
aims to provide for sustainable operations until the mine's closure and has 
resulted in a labour reduction process to align the operation with the reduced 
tonnage profile. This process was concluded and the mine started on a new shift 
configuration with the reduced labour structure on 30 June 2022. 
 
The on-mine cash unit cost increased to ZAR1,106/t, mainly due to decreased 
tonnages and inflationary increases. FY 2022 capex was US$0.6 million and this 
was spent mainly on the completion of a workshop underground. 
 
Guidance 
 
FY 2023 to FY 2025 production, cost and capex guidance is maintained and takes 
into account the lower production and cost profile we have put in place. 
 
  * The total on-mine cash cost for FY 2023 is guided at between ZAR415 and 
    ZAR437 million in real terms. 
  * FY 2023 capex guidance is between c.US$1 and US$2 million, primarily 
    relating to sustaining costs.

Notes: 
 
The Group uses several non-GAAP measures above and throughout this report to 
focus on actual trading activity by removing certain non-cash or non-recurring 
items. These measures include adjusted mining and processing costs, profit from 
mining activities, adjusted EBITDA, adjusted net profit after tax, adjusted 
earnings per share, adjusted US$ loan note, net debt and consolidated net debt 
for covenant measurement purposes.  As these are non-GAAP measures, they should 
not be considered as replacements for IFRS measures. The Group's definition of 
these non-GAAP measures may not be comparable to other similarly titled 
measures reported by other companies. The Board believes that such alternative 
measures are useful as they exclude one-off items such as the impairment 
charges and non-cash items to provide a clearer understanding of the underlying 
trading performance of the Group. 
 
 1. Adjusted mining and processing costs are mining and processing costs stated 
    before depreciation. 
 2. Profit from mining activities is revenue less adjusted mining and 
    processing costs plus other direct income. 
 3. Adjusted EBITDA is stated before depreciation, amortisation of right-of-use 
    asset, share-based expense, net finance expense, tax expense,  impairment 
    reversal/charges, expected credit loss release/ (charge), gain on 
    extinguishment of Notes net of unamortised costs, profit on disposal of 
    subsidiary, costs and fees relating to investigation and settlement of 
    human rights abuse claims, provision for unsettled and disputed tax claims 
    and net unrealised foreign exchange gains and losses. 
 4. Adjusted net profit/(loss) after tax is net profit/(loss) after tax stated 
    before impairment reversal/charge, expected credit release (loss) 
    provision, gain on extinguishment of Notes net of unamortised costs, costs 
    and fees relating to investigation and settlement of human rights abuse 
    claims, profit on disposal net unrealised foreign exchange gains and 
    losses, and excluding taxation (charge) credit on net unrealised foreign 
    exchange gains and losses and excluding taxation credit on impairment 
    charge. 
 5. Impairment reversal of US$19.6 million (30 June 2021: US$38.4 million 
    charge) was due to the Group's impairment review of its operations and 
    other receivables. Refer to note 15 below for further details. 
 6. Reversal of impairment of BEE loans receivable of US$nil (30 June 2021: 
    US$5.8 million) is due to the Group's expected credit loss assessment of 
    its BEE loans receivable. Refer to note 11 below for further details. 
 7. The profit on disposal of subsidiary of US$14.7 million in FY2021 includes 
    the reclassification of foreign currency translation reserve, net of tax of 
    Sekaka Diamonds (Pty) Ltd. 
 8. Adjusted EPS is stated before impairment charge, expected credit release 
    (loss) provision, gain on extinguishment of Notes net of unamortised costs, 
    profit on disposal of subsidiary, acceleration of unamortised costs on 
    restructured loans and borrowings, costs and fees relating to investigation 
    and settlement of human rights abuse claims, provision for unsettled and 
    disputed tax claims, net unrealised foreign exchange gains and losses, and 
    excluding taxation (charge) credit on net unrealised foreign exchange gains 
    and losses and excluding taxation credit/charge on impairment reversal/ 
    charge. 
 
The comparative basic profit per share and adjusted profit per share have been 
adjusted to give effect to the share consolidation of one new share for every 
50 existing shares completed on 29 November 2021 with the Company's resultant 
issued share capital now consisting of 194,201,785 ordinary shares of 0.05 
pence each. 
 
 1. The US$336.7 million loan notes have a carrying value of US$366.2 million 
    (FY2021: US$327.3 million) which represents the gross capital of US$336.7 
    million of notes, plus accrued interest and net of unamortised transaction 
    costs capitalised, issued following the capital restructuring (the 
    "Restructuring") completed during March 2021. Refer to detailed Debt 
    Restructuring Note 18. 
 2. Bank loans and borrowings represent amounts drawn under the Group's 
    refinanced South African banking facility with ABSA, completed in June 
    2022.  As at 30 June 2022 the new facility with ABSA comprises a ZAR1 
    billion (US$61.5 million) revolving credit facility which remains undrawn 
    and available. 
 
During the Year, the South African banking facilities held with the Group's 
previous consortium of South African lenders were settled and cancelled, 
comprising of the revolving credit facility of ZAR404.6 million (US$24.9 
million) (capital plus interest) and the term loan of ZAR893.2 million (US$54.9 
million) (capital plus interest). 
 
 1. Consolidated Net Debt is bank loans and borrowings plus loan notes, less 
    cash, less diamond debtors plus BEE partner bank facilities. In FY2021 
    Williamson was classified as held for sale, if Williamson was consolidated 
    as at 30 June 2021 consolidated net debt would have reduced by cash and 
    cash equivalents held by Williamson of US$9.2 million to US$219.0 million. 
 2. Tax (expense) / credit is the tax (expense) / credit for the Period 
    excluding taxation credit / (charge) on impairment charge and unrealised 
    foreign exchange gain / (loss) generated during the Period, such exclusion 
    more accurately reflects resultant Adjusted net profit / (loss). 
 3.  Williamson's diamond inventory includes the 71,654.45 carat parcel of 
    diamonds blocked for export during August 2017, with a carrying value of 
    US$12.5 million. In terms of the framework agreement reached with the 
    Government of Tanzania, as announced on 13 December 2021, the proceeds from 
    the sale of this parcel will be allocated to Williamson. 
 4. Operational free cashflow is defined as cash generated from operations less 
    acquisition of property, plant and equipment. 
 5. The results for FY2021 has been restated with the operating results of 
    Williamson which were previously classified under loss on discontinued 
    operations, for further detail refer to note 17. 
 
Revenue 
 
Total revenue for FY 2022 amounted to US$585.2 million (FY 2021: US$406.9 
million), comprising revenue from rough diamond sales of US$584.1 million (FY 
2021: US$406.9 million) and additional revenue from profit share agreements of 
US$1.1 million (FY 2021: nil). 
 
FY 2022 revenue from rough diamond sales increased 44% to US$584.1 million (FY 
2021: US$406.9 million) driven by sales from a higher than average number of 
Exceptional Stones contributing US$89.1 million during the Year (FY 2021: 
US$62.0 million); supported by the strong diamond market, and a 41.5% increase 
in like-for-like diamond prices. 
 
Mining and processing costs 
 
The mining and processing costs for FY 2022 comprised on-mine cash costs as 
well as other operational expenses. A breakdown of the total mining and 
processing costs for the Year is set out below.

Notes: 
 
 1. Includes all direct cash operating expenditure at operational level, i.e. 
    labour, contractors, consumables, utilities and on-mine overheads. 
 2. Certain technical, support and marketing activities are conducted on a 
    centralised basis. 
 3. Includes amortisation of right-of-use assets under IFRS 16 of US$2.3 
    million (FY 2021: US$0.6 million) and excludes exploration and corporate / 
    administration. 
 4. For comparative purposes, the FY 2021 figures include Williamson as it is 
    no longer held for sale at 30 June 2022. 
 
Absolute on-mine cash costs in FY 2022 increased by c.30% compared to FY 2021 
and in line with expectations, due to: 
 
  * The effect of translating ZAR denominated costs at the South African 
    operations at a stronger ZAR/USD average exchange rate (1.4% increase) 
  * Williamson mine resuming production in FY 2022 after being on care and 
    maintenance throughout FY 2021 and changes in volumes at South-African 
    operations (18.3% increase); 
  * Other cost movements, due to increased social expenditure and costs 
    previously included under Group technical, support and marketing costs 
    (1.2% increase) 
  * Inflationary increases (c.6.8% increase), the impact of electricity costs 
    (0.9% increase) and annual labour increases and voluntary separation 
    pay-outs (1.4% increase) 
 
Royalties increased to US$14.6 million (FY 2021: US$3.2 million) due to 
increased profits net of capex across the SA operations resulting in higher 
royalty percentages, as defined in the royalty legislation of South Africa and 
Williamson recommencing operations during the Year. 
 
Profit from mining activities 
 
Profit from mining activities increased 102% to US$277.3 million (FY 2021: 
US$137.6 million), mainly due to improved diamond pricing and the contributions 
from Exceptional Stones. 
 
Adjusted corporate overhead - general and administration 
 
Corporate overhead (before depreciation and share based payments) increased to 
US$13.0 million for the Year (FY 2021: US$7.4 million) mainly attributable to 
the increase in corporate governance structures, strategic developments and 
Board appointments introduced during the Year. 
 
Adjusted EBITDA 
 
Adjusted EBITDA, being profit from mining activities less adjusted corporate 
overhead, increased 103% to US$264.9 million (FY 2021: US$130.2 million), 
representing an adjusted EBITDA margin of 45% (FY 2021: 32%) driven by the 
stronger diamond market and resultant improved diamond pricing coupled with the 
contribution from Exceptional Stones. 
 
Depreciation and amortisation 
 
Depreciation and amortisation for the Period increased to US$85.3 million (FY 
2021: US$80.8 million), mainly due to production recommencing at Williamson. 
 
Impairment reversal / charge 
 
As a result of the impairment reviews carried out at the Cullinan, Finsch, 
Koffiefontein and Williamson Mines, and the Group's other receivables during 
the Year, the Board recognised an overall net impairment reversal of US$19.6 
million (FY 2021: US$38.4 million impairment charge), comprising: 
 
US$ million                                                   FY 2022    FY 2021

Impairment reviews carried out at the Cullinan, Finsch, and Williamson Mines' 
operational assets did not result in an impairment charge or reversal during 
the Year (FY 2021: US$38.7 million). Asset level impairments at Koffiefontein 
amount to US$0.3 million (FY 2021: US$38.7 million in respect of Finsch, 
Koffiefontein and Williamson), of the Group's carrying value of property, plant 
and equipment of US$608.2 million (FY 2021: US$764.5 million) pre-impairment. 
There was an impairment reversal of US$21.4 million relating to an IFRS 5 
impairment adjustment for Williamson as the results for Williamson have been 
re-consolidated. 
 
Impairment of BEE loans receivable - expected credit loss provision 
 
The Group has applied the expected credit loss impairment model to its BEE 
loans receivable. In determining the extent to which expected credit losses may 
apply, the Group assessed the future free cashflows to be generated by the 
mining operations based on the current mine plans. This assessment indicated a 
net credit loss reversal / charge of US$nil (FY 2021: US$5.8 million expected 
credit loss reversal); refer to note 2 for further detail. 
 
Net financial (expense)/income 
 
Net financial expense of US$73.1 million (FY 2021: US$220.7 million income) 
comprises:

Tax credit / charge 
 
The tax charge of US$37.8 million (FY 2021: US$23.0 million) comprising 
deferred tax charge of US$30.4 million (FY 2021: US$22.7 million) and a net 
current tax charge of US$7.4 million (FY 2021: US$0.3 million). 
 
The Consolidated Income Statement deferred tax charge for the Year reflects 
movements in deferred tax of US$35.5 million (30 June 2021: US$3.4 million) in 
respect of property, plant and equipment and associated capital allowances, 
US$2.5 million deferred tax credit (30 June 2021: US$2.8 million) relating to 
provisions and a US$2.6 million deferred tax credit (30 June 2021: US$nil) due 
to the change in the South African corporate tax rate from 28% to 27% reducing 
the deferred tax liabilities recognised at the Finsch and Cullinan Mines at 
Year end. 
 
The net current tax charge of US$7.4 million (30 June 2021: US$0.3 million 
includes a current tax charge of US$7.6 million at Finsch for the Year (FY 
2021: US$nil million). 
 
Profit on disposal of subsidiary including associated impairment, net of tax 
 
In FY 2021, the profit on disposal of subsidiary including associated 
impairment, net of tax of US$14.7 million relates to the Group's disposal of 
its interests in Sekaka, its exploration operations in Botswana, and is made up 
of a US$0.3 million disposal consideration, net profit of US$1.3 million for 
the Period 1 July 2020 to the 30 November 2020 disposal date and the recycling 
of the foreign currency translation reserve of US$13.3 million, offset by a net 
asset disposal amount of US$0.2 million. Refer to Note 16 for further detail. 
 
Williamson 
 
At the end of FY 2021, the Board had decided to review its strategic options at 
Williamson and the asset was classified as an asset held for sale. 
 
In terms of the IFRS requirements to measure the assets of a disposal group at 
the lower of carrying amount and fair value less costs to sell, the 
determination of the fair value is complex and subject to considerable 
judgement. Based on management's best estimate of the fair value at 30 June 
2021, the following amounts were recognised as a result of that 
reclassification: 
 
  * An impairment charge of US$21.4 million in respect of property, plant and 
    equipment 
  * A US$11.2 million charge attributable to Williamson's net loss for FY 2021 
  * A US$19.5 million provision for unsettled and disputed tax claims arising 
    from the ordinary course of business 
 
During H1 FY 2022, the Group entered into a Framework Agreement with the 
Government of Tanzania regarding the Williamson mine which will reduce Petra's 
indirect shareholding from 75% to 63%.  Petra also entered into a non-binding 
Memorandum of Understanding ("MoU") to sell 50% less one share of the entity 
that holds Petra's shareholding in Williamson ("WDL") to Caspian Limited. Upon 
completion of the transactions contemplated by the MoU and the capital 
restructuring in the Framework Agreement becoming effective (expected in H1 FY 
2023), Petra and Caspian will each indirectly hold a 31.5% stake in WDL, but 
with Petra retaining a controlling interest in WDL, and the Government of 
Tanzania holding the remaining 37%. These agreements are in line with Petra's 
objective of reducing its exposure in Tanzania while retaining control, through 
its controlling interest in the entity that holds Petra's shares in WDL. The 
Williamson mine is therefore no longer classified as an asset held for sale in 
FY 2022 and was reconsolidated into the Group results for FY 2022. As a result 
the Group also reversed a Group level impairment charge relating to Williamson, 
previously recognised under IFRS 5, of US$21.4 million. Refer to Note 17 for 
additional detail. 
 
Earnings per share 
 
Basic profit per share from continuing operations of USc35.53 was recorded (FY 
2021: USc260.70, including gain on extinguishment of Notes). 
 
Adjusted profit per share from continuing operations (adjusted for impairment 
charges, taxation credit on net unrealised foreign exchange losses and net 
unrealised foreign exchange gains and losses) of USc42.93  was recorded (FY 
2021: USc36.20 loss (adjusted for impairment charges, taxation charge on net 
unrealised foreign exchange gains and net unrealised foreign exchange gains and 
losses)). 
 
The comparative basic profit per share and adjusted profit per share have been 
adjusted to give effect to the share consolidation of one new share for every 
50 existing shares completed on 29 November 2021, with the Company's resultant 
issued share capital now consisting of 194,201,785 ordinary shares of 0.05 
pence each. 
 
Operational free cash flow 
 
During the Year, operational free cash flow of US$230.0 million (FY 2021: 
US$120.1 million before restructuring fees of US$15.5 million) reflects the 
impact from the sale of a high number of Exceptional Stones and stronger 
diamond prices. This strong cash flow performance was positively impacted by: 
 
  * US$7.6 million inflow (FY 2021: US$12.1 million outflow) cash finance 
    expenses net of finance income and net realised foreign exchange gains/ 
    (losses). 
 
This was offset by: 
 
  * Restructuring fees settled during the Year of US$nil (FY 2021 US$29.9 
    million) 
  * Income tax paid of US$7.8 million (FY 2021: US$0.3 million inflow) 
  * US$3.5 million dividend paid to BEE partners (FY 2021: US$7.0 million 
    advances to BEE partners, largely related to servicing of BEE bank debt, 
    with the advances recoverable against future BEE partner distributions) 
 
Cash and Diamond Debtors 
 
As at 30 June 2022, Petra had cash at bank of US$288.2 million (FY 2021: 
US$163.9 million). Of these cash balances, US$271.9 million was held as 
unrestricted cash (FY 2021: US$147.8 million), US$15.5 million was held by 
Petra's reinsurers as security deposits on the Group's cell captive insurance 
structure (with regards to the Group's environmental guarantees) (FY 2021: 
US$15.3 million) and US$0.8 million was held by Petra's bankers as security for 
other environmental rehabilitation bonds lodged with the Department of Mineral 
Resources and Energy in South Africa (FY 2021: US$0.8 million). 
 
Diamond debtors at 30 June 2022 were US$37.4 million (FY 2021: US$38.3 
million). 
 
Loans and Borrowings 
 
The Group had loans and borrowings (measured under IFRS) at Year end of 
US$366.2 million (FY 2021: US$430.3 million) comprised of US$366.2 million 
Notes (includes US$50.3 million accrued interest and unamortised transaction 
costs of US$15.2 million), bank loans and borrowings of US$nil  (FY 2021: 
US$103.0 million). Bank debt facilities undrawn and available to the Group at 
30 June 2022 were US$61.5 million (FY 2021: US$7.7 million). 
 
Consolidated net debt at 30 June 2022 was US$40.6 million (FY2021: US$228.2 
million). 
 
Covenant Measurements attached to banking facilities

Going concern considerations 
 
The Board has reviewed the Group's forecasts with various sensitivities 
applied, for the 18 months to December 2023, including both forecast liquidity 
and covenant measurements. As per the First Lien agreements, the liquidity and 
covenant measurements exclude contributions from Williamson's trading results 
and only recognises cash distributions payable to Petra upon forecasted 
receipt, or Petra's funding obligations towards Williamson upon payment. The 
review took into account the Groups intention to purchase up to US$150 million 
of the Senior Secured Second Lien Notes due in 2026 through a tender offer to 
bondholders. 
 
The Board has given careful consideration to potential risks identified in 
meeting the forecasts under the review period. The following sensitivities have 
been performed in assessing the Group's ability to operate as a going concern 
(in addition to the Base Case) at the date of this report: 
 
  * A 10% decrease in forecast rough diamond prices from July 2022 to December 
    2023 
  * A 10% strengthening in the forecast South African Rand (ZAR) exchange rate 
    against the US Dollar from July 2022 to December 2023 
  * A 10% increase in operating costs from July 2022 to December 2023 
  * A US$15 million reduction in revenue contribution from Exceptional Stones 
  * A production disruption sensitivity assuming no carat production across the 
    Group for two weeks in February 2023 (could be due to extreme weather 
    conditions or supply chain disruptions or any other unexpected event) 
 
  * Combined sensitivity: Prices down 10% and ZAR stronger by 10%, reduced 
    contribution from Exceptional Stones and operating costs up 5% 
 
Under all the cases, the forecasts indicate that the Group's liquidity outlook 
over the 18-month period to December 2023 remains strong, even when applying 
the above sensitivities to the base case forecast. 
 
The forward-looking covenant measurements associated with the new First Lien 
(1L) facility do not indicate any breaches during the 18-month review period 
for the base case as well as all the above sensitivities, except for the 
combined sensitivity, which shows a covenant breach for the required ICR in the 
December 2023 measurement period. While the ICR is projected to be breached in 
this combined sensitivity, neither the Net Debt : EBITDA covenant nor the 
liquidity covenant is projected to be breached, while the revolving credit 
facility (RCF) remains undrawn. It is therefore assumed that the RCF remains 
available on the expectation that the 1L lender will agree to an ICR covenant 
waiver given that the Group does not expect to utilise the RCF for servicing of 
its Second Lien (2L) interest obligations. Furthermore, this potential ICR 
breach may be cured by means of reducing of our gross debt by utilising 
existing available cash reserves and/or marginally increasing our projected 
EBITDA for the preceding 12-month period. 
 
As a result, the Board concluded that there are no material uncertainties that 
would cast doubt on the Company continuing as a going concern.  See 'Basis of 
preparation including going concern' in the Financial Statements for further 
information. 
 
Capex 
 
Total Group capex for the Year increased to US$52.2 million (FY 2021: US$23.8

  * US$34.5 million expansion capex (FY 2021: US$16.9 million) 
  * US$17.7 million sustaining capex (FY 2021: US$6.9 million).

PRINCIPAL BUSINESS RISKS 
 
The Group is exposed to a number of risks and uncertainties which could have a 
material impact on its long-term development, and performance and management of 
these risks is an integral part of the management of the Group. 
 
A summary of the risks identified as the Group's principal external, operating 
and strategic risks (in no order of priority), which may impact the Group over 
the next twelve months, is listed below.

External Risks 
 
1.  Rough      High     Medium   Long     Lower - like for like diamond prices 
diamond price                    term     increased 41.5% (FY 2021: 9%) during FY 2022 
                                          which was largely attributable to mid-stream 
                                          inventory restocking and continued strong 
                                          jewellery retail sales. Lower global diamond 
                                          production also resulted in a more positive 
                                          outlook for the diamond market whilst 
                                          macroeconomic uncertainties caused by rising 
                                          interest rates and inflation are potential 
                                          dampeners of demand. 
 
2. Currency    High     Medium   Long     No change - whilst initially stable, the ZAR/ 
                                 term     USD exchange rate experienced significant 
                                          volatility during FY 2022, closing the Year 
                                          at 16.27 ZAR/USD, compared to 14.27 ZAR/USD 
                                          on 30 June 2021. The impact of the war in 
                                          Ukraine benefitted the Rand, though over the 
                                          longer term the Rand is expected to weaken as 
                                          South Africa's inflation rate remains high. 
 
3. Country     High     Medium   Long     Lower - while the risk of political 
and political                    term     instability remains in South Africa, the 
                                          outcomes of the ruling party's policy 
                                          conference were positive and markets were 
                                          encouraged by party support for the 
                                          President's proposals. After the South 
                                          African High Court judgement in favour of the 
                                          Minerals Council SA, the DMRE has indicated 
                                          it will seek legislative amendments of the 
                                          Mineral and Petroleum Resources Development 
                                          Act which could reverse aspects of the 
                                          judgement, in particular the legal status of 
                                          the Mining Charter. In Tanzania, the risk of 
                                          political instability remains lower under the 
                                          new President and following entry by Petra 
                                          into a Framework Agreement with the 
                                          Government that is yet to become effective

                                          led, in South Africa, to the termination of 
                                          the national state of emergency. The emphasis 
                                          has shifted to continuing the promotion of 
                                          the administration of vaccinations, including 
                                          booster shots, as this remains the best 
                                          protection against COVID-19. 
 
 
 
 
 
Strategic 
Risks 
 
5. Group       Medium   Medium   Short to Lower - a combination of higher diamond 
Liquidity                        medium   prices, robust production levels in line with 
                                 term     guidance and record proceeds from the sale of 
                                          Exceptional Stones contributed to increased 
                                          revenue, strong free cash flow and a 
                                          reduction in net debt to US$40.6 million as 
                                          at 30 June 2022, thereby significantly 
                                          strengthening the balance sheet. The Company 
                                          also completed the refinancing of its first 
                                          lien debt facility which will deliver some 
                                          US$5 million in savings over the next two 
                                          years as a result of reduced utilisation and 
                                          more favorable terms than the previous 
                                          facility.

                                          Stakeholder engagement plans (SEPs) continue 
                                          to be reviewed and updated to increase 
                                          value-add engagements at Government and 
                                          community levels. 
                                          Following the Company's May 2021 announcement 
                                          on the alleged human rights breaches in 
                                          Tanzania, Petra has continued to progress the 
                                          design and implementation of the IGM for 
                                          Williamson.  This has involved extensive 
                                          stakeholder engagements with all levels of 
                                          Government and the local community to create 
                                          awareness of the IGM process and to obtain 
                                          initial feedback on how the IGM is envisaged 
                                          to operate.  The current target is for the 
                                          IGM to become operational during Q2 CY 
                                          2023. 
                                          The Company has also progressed a number of 
                                          projects to provide sustainable benefits to 
                                          the communities located close to the 
                                          Williamson mine which include (1) a medical 
                                          support project, (2) an artisanal and 
                                          small-scale mining project, (3) an 
                                          agribusiness development initiative, (4) 
                                          improved delineation of the Williamson mine 
                                          boundaries, including access to the mine 
                                          lease area for the collection of firewood and 
                                          (5) an awareness initiative in respect of 
                                          sexual and gender-based violence.

7. Mining and  Medium   Medium   Long     Lower - positive throughput improvements 
production                       term     supported by Project 2022 (which completed 
                                          in June 2022) continued to yield good 
                                          results. Group production for FY 2022 
                                          increased by 3% in line with guidance, 
                                          largely owing to the resumption of mining at 
                                          Williamson. Production at the Cullinan Mine 
                                          during Q4 FY 2022 was lower due to the 
                                          depletion of the current CC1E mining area 
                                          and a difference in the make-up of 
                                          kimberlite in the C-Cut. When compared with 
                                          FY2021, production at the Finsch Mine 
                                          stabilised in the second half of FY 2022, 
                                          although ROM grade was 13% lower as a result 
                                          of waste dilution despite the implementation 
                                          of controls which were continuously 
                                          monitored. Group production guidance for 
                                          FY2023 to FY 2025 remains unchanged at this 
                                          stage. 
 
8. ROM grade   Medium   Medium   Short    No change - the current mining blocks at the 
and product                      term     South African operations are reaching 
mix volatility                            maturity and while the current orebody 
                                          footprints are still large enough to deliver 
                                          relative consistency and product mix, 
                                          increasing levels of variability in terms of 
                                          ROM Grade and product mix can be expected 
                                          going forwards which will be mitigated by 
                                          the ramp up of the new mining blocks at CDM 
                                          and FDM. 
 
9. Labour      Medium   Medium   Short to No change - stable labour relations were 
relations                        medium   experienced during FY 2022. The Company 
                                 term     reached agreement with NUM on a new 
                                          three-year wage agreement for employees in 
                                          the Paterson A and B Bands at the South 
                                          African operations. The Company also 
                                          concluded a three-year wage agreement for 
                                          employees on the Paterson C-Lower Band with 
                                          both NUM and UASA at the SA operations.

                                          agreement at WDL is ongoing with the 
                                          majority union (TAMICO). 
 
10. Safety     Medium   Medium   Short to Lower - Petra's safety performance saw a 40% 
                                 medium   reduction in Lost Time Injuries (LTIs) to 15 
                                 term     for the Year and a corresponding 48% 
                                          improvement in the Lost Time Injury Frequency 
                                          Rate for the Year.  The only metric on which 
                                          Petra's performance deteriorated was in 
                                          respect of Non-Lost Time Injuries, which saw 
                                          an increase of 11% but this was against a 
                                          backdrop of (i) an increased number of LTIs 
                                          incurred in FY 2021 versus the low number of 
                                          incurred NLTIs in FY 2021 and (ii) an 
                                          increased number of shifts worked in FY 2022 
                                          which meant Petra's Non-Lost Time Injury 
                                          Frequency Rate improved by 7%.  The Cullinan 
                                          Mine in particular, had an exceptional year, 
                                          celebrating a LTI-free year on 25 April 2022.

                                          has resulted in higher waste recycling (25% 
                                          more waste was recycled in FY 2022 than in 
                                          the previous year) and lowered the risk 
                                          caused by landfilling.  On land

                                          disturbed land during FY 2022.  The 
                                          implementation of annual objectives for 
                                          improved water efficiency has seen Petra 
                                          reach internal water recycling figures 
                                          averaging 80% over the last four years.

NOTES TO THE CONDENSED CONSOLIDATED PRELIMINARY FINANCIAL STATEMENTS 
 
FOR THE YEARED 30 JUNE 2022 
 
1.    GENERAL INFORMATION 
 
Petra Diamonds Limited (the "Company"), a limited liability company listed on 
the Main Market of the London Stock Exchange, is registered in Bermuda with its 
Group management office domiciled in the United Kingdom. The Consolidated 
Interim Financial Statements of the Company for the year ended 30 June 2022 
comprise the Company and its subsidiaries, joint operations and associates 
(together referred to as the "Group"). 
 
2.    ACCOUNTING POLICIES 
 
This preliminary report, which is unaudited, does not include all the notes of 
the type normally included in an annual financial report. This condensed report 
is to be read in conjunction with the Annual Report for the year ended 30 June 
2021, and any public announcements made by the Group during the reporting 
period. The annual financial report for the year ended 30 June 2021 was 
prepared in accordance with International Financial Reporting Standards as 
adopted by the European Union ("IFRS's") and the accounting policies applied in 
this condensed preliminary report are consistent with the polices applied in 
the annual financial report for the year ended 30 June 2021 unless otherwise 
noted. The preliminary report has been prepared in accordance with accounting 
policies compliant with International Financial Reporting Standards as adopted 
by the European Union. 
 
Basis of preparation including going concern 
 
The twelve-month period to 30 June 2022 delivered US$264.9 million in EBITDA 
and US$230.0 million in operational free cash flow for the Group, while 
Consolidated Net Debt reduced from $228.2 million as at 30 June 2021 to US$40.6 
million at 30 June 2022. 
 
Production 
 
Production at both CDM and FDM were generally in line with guidance. The 
Group's overall production also benefitted with the restart of operations at 
Williamson during Q1 FY2022 following an 18-month period of care and 
maintenance, with Williamson ramping up towards steady-state operations. During 
the Year, the Group also announced expansion capital projects at both the 
Cullinan and Finsch Mines, which will extend their Life of Mine plans to 2031 
and 2030 respectively. The expansion project at Cullinan Mine is progressing 
well, while the expansion project at Finsch is slightly behind schedule on 
account of delay in delivery of long-lead items given the global disruption in 
supply chains experienced over the past 6 months. Both projects, however, 
remain within guidance for cost and schedule, as mitigation steps have been 
identified and being implemented to catch-up on the schedule delays at Finsch. 
 
Diamond prices and diamonds market 
 
Diamond prices strengthened over FY 2022, with a 41.5% increase on a 
like-for-like basis compared to the preceding twelve-month period. In addition, 
CDM's run of Exceptional Stone recovery and sales continued with a total of 
US$75.2 million realised in the Year. Williamson also benefited from the sale 
of an exceptional pink diamond at its first tender after restarting operations, 
yielding $13.8 million and significantly de-risking Williamson's own liquidity 
profile. 
 
The market witnessed robust price recovery and are now close to prices last 
seen during pre-COVID-19 levels. In general, the market is supported by a 
fundamental supply deficit, with robust demand recovery experienced post 
COVID-19. While some of the price recovery may have been helped by sanctions on 
Russian goods, it appears that these goods have continued to flow into the 
market. From a demand perspective, the Chinese lockdown has moderated demand 
for certain categories of polished goods, while the rising inflation and 
interest rate cycles may impact disposable income and therefore further 
moderate/reduce short-term demand for diamonds. This may lead to some 
short-term price volatility, but the medium-long term supply/demand 
fundamentals are expected to support the diamond price outlook. 
 
Williamson framework agreement and MOU 
 
The Group announced reaching a framework agreement with the Government of 
Tanzania in December 2021, which sets out key principles on the economic 
benefit sharing amongst shareholders, treatment of outstanding VAT balances, as 
well as agreement reached on the blocked parcel of diamonds and settlement of 
historic disputes, amongst others. This agreement should provide important 
fiscal stability for the mine and its investors and is expected to become 
effective during the first half of FY2023, pending completion of certain 
suspensive conditions. At the same time, Petra also announced entering into a 
Memorandum of Understanding (MOU) with Caspian Ltd to sell 50% less 1 share of 
Petra's stake in Williamson to this Tanzanian company for a purchase 
consideration of US$15 million, which is also expected to be effective in the 
first half of FY2023. 
 
COVID-19 
 
Petra's approach to managing COVID-19 has seen the Group not experiencing 
interruptions to our day-to-day operational/business activities specifically 
related to COVID-19 during the Year. During FY2022, we successfully reverted to 
hosting all of our tenders for our South African goods in South Africa, while 
the Williamson goods continue to be auctioned in Belgium (as per our normal 
tender process for Williamson goods). 
 
South African banking facilities 
 
During the Year, the South African banking facilities held with the Group's 
previous consortium of South African lenders were settled and cancelled, 
comprising of the revolving credit facility of ZAR404.6 million (US$24.9 
million) (capital plus interest) and the term loan of ZAR893.2 million (US$54.9 
million) (capital plus interest). 
 
The Group entered into a new ZAR 1 billion senior Revolving Credit Facility 
(RCF) facility in June 2022. The Group will benefit from reduced interest rates 
compared to the previous facilities coupled with more appropriate 
leverage-based covenants (Net Debt : EBITDA, Interest Cover Ratio and minimum 
liquidity). This new facility has a longer tenure, with the facility expiring 
on January 7, 2026. As at June 30, 2022, the RCF remains undrawn, with the 
Group having access to the full ZAR 1 billion (US$ 61.5 million). 
 
The factors above, coupled with the further significant progress towards 
stabilising the Group's balance sheet and strengthening cash reserves as at the 
date of this report positions the Group well for this Going Concern period. 
 
Forecast liquidity and covenants 
 
The Board has reviewed the Group's forecasts with various sensitivities applied 
for the 18 months to December  2023, including both forecast liquidity and 
covenant measurements. As per the First Lien agreements, the liquidity and 
covenant measurements exclude contributions from Williamson's trading results 
and only recognises cash distributions payable to Petra upon forecasted 
receipt, or Petra's funding obligations towards Williamson upon payment. 
 
Debt tender offer 
 
The Group intends to reduce its gross debt through a tender offer to 
bondholders to purchase up to US$150 million of the Senior Secured Second Lien 
Notes due in 2026 in line with our stated intent to further optimise our 
capital structure through a reduction of gross debt.  If completed, the 
transaction will see Petra saving up to US$15 million per annum in interest 
expenses while we remain confident in our liquidity outlook to continue to fund 
our ongoing capital programmes from existing and internally generated cash 
resources. 
 
The Board has given careful consideration to potential risks identified in 
meeting the forecasts under the review period. The following sensitivities have 
been performed in assessing the Group's ability to operate as a going concern 
(in addition to the Base Case) at the date of this report: 
 
  * a 10% decrease in forecast rough diamond prices from July 2022 to Dec 2023 
  * a 10% strengthening in the forecast South African Rand (ZAR) exchange rate 
    from July 2022 to Dec 2023 
  * a 10% increase in Operating Costs from July 2022 to Dec 2023 
  * a US$15 million reduction in revenue contribution from Exceptional Stones 
  * a production disruption sensitivity assuming no carat production across the 
    Group's operations for a period of two weeks in February 2023 (could be due 
    to extreme weather conditions or supply chain events or any other 
    unexpected event) 
  * Combined sensitivity: Prices down 10% and ZAR stronger by 10% and 
    Exceptional Stones contributions reduced by US$15 million and Operating 
    Costs up 5% 
 
Under all the cases, the forecasts indicate the Group's liquidity outlook over 
the 18-month period to December 2023 remains strong, even when applying the 
above sensitivities to the base case forecast. 
 
The forward-looking covenant measurements associated with the new First Lien 
facility do not indicate any breaches during the 18-month review period for the 
base case as well as all the above sensitivities, except for the worse case 
combined sensitivity, which shows a covenant breach for the required interest 
cover ratio in the December 2023. While the ICR is projected to be breached in 
this combined sensitivity, both the Net Debt : EBITDA covenant and the 
liquidity covenant remain healthy, while the RCF remains undrawn. It is 
therefore assumed that the RCF remains available, with the 1L lender assumed to 
agree to an ICR covenant waiver, given that the Group does not expect to 
utilise the RCF for servicing of its 2L interest obligations. Furthermore, this 
potential ICR breach may be cured by means of reducing of our gross debt by 
utilising our cash reserves and/or marginally increasing our EBITDA for the 
preceding 12-month period. 
 
Conclusion 
 
The Board is of the view that the longer-term fundamentals of the diamond 
market remain sound and that the Group will continue to benefit from the 
recently embedded new operating model throughout the review period and beyond. 
 
Based on its assessment of the forecasts, principal risks and uncertainties and 
mitigating actions considered available to the Group in the event of downside 
scenarios, the Board confirms that it is satisfied the Group will be able to 
continue to operate and meet its liabilities as they fall due over the going 
concern period to December 2023. Accordingly, the Board have concluded that the 
going concern basis in the preparation of the financial statements is 
appropriate and that there are no material uncertainties that would cast doubt 
on that basis of preparation. 
 
New standards and interpretations applied 
 
The IASB has issued new standards, amendments and interpretations to existing 
standards with an effective date on or after 1 July 2021 which are not 
considered to have a material impact on the Group during the Period under 
review. 
 
New standards and interpretations not yet effective 
 
Certain new standards, amendments and interpretations to existing standards 
have been published that are mandatory for the Group's accounting periods 
beginning after 1 July 2022 or later periods. The only standard which is 
anticipated to be significant or relevant to the Group is: 
 
Amendments to IAS 1: Classification of Liabilities as Current or Non-current 
 
Amendments to IAS 1, which are intended to clarify the requirements that an 
entity applies in determining whether a liability is classified as current or 
non-current. The amendments are intended to be narrow scope in nature and are 
meant to clarify the requirements in IAS 1 rather than modify the underlying 
principles. The amendments include clarifications relating to: 
 
  * how events after the end of the reporting period affect liability 
    classification; 
  * what the rights of an entity must be in order to classify a liability as 
    non-current; 
  * how an entity assesses compliance with conditions of a liability (e.g. bank 
    covenants); and 
  * how conversion features in liabilities affect their classification. 
 
The amendments were originally effective for periods beginning on or after 1 
January 2022 which was deferred to 1 January 2023 by the IASB in July 2020. 
Earlier application is permitted but Amendments to IAS 1 has not yet been 
endorsed for application by the European Union. 
 
Significant assumptions and judgements: 
 
The preparation of the condensed consolidated interim financial statements 
requires management to make estimates and judgements and form assumptions that 
affect the reported amounts of the assets and liabilities, reported revenue and 
costs during the periods presented therein, and the disclosure of contingent 
liabilities at the date of the interim financial statements. Estimates and 
judgements are continually evaluated and based on management's historical 
experience and other factors, including future expectations and events that are 
believed to be reasonable. The estimates and assumptions that have a 
significant risk of causing a material adjustment to the financial results of 
the Group in future reporting periods are discussed below. 
 
Key estimates and judgements: 
 
Impairment reviews 
 
The Group prepares impairment models and assesses mining assets for impairment 
or reversals of previous impairments. While conducting an impairment test of 
its assets using recoverable values using the current life of mine plans, the 
Group exercised judgement in making assumptions about future rough diamond 
prices, foreign exchange rates, volumes of production, ore reserves and 
resources included in the current life of mine plans, future development and 
production costs and factors such as inflation and discount rates. Changes in 
estimates used can result in significant changes to the 'Consolidated Income 
Statement' and 'Statement of Financial Position'. 
 
Cullinan, Finsch, Koffiefontein and Williamson 
 
The impairment tests for the Cullinan and Finsch Mines indicated no further 
impairment charges or reversals to be recognised. The impairment test for 
Koffiefontein indicated an impairment of US$0.3 million on a carrying value of 
the Group's property, plant and equipment of US$608.2 million (pre-impairment). 
This follows US$17.3 million recognised at 30 June 2021 (comprising Finsch 
impairment of US$15.1 million and Koffiefontein impairment of US$2.2 million) 
on a carrying value of the Group's property, plant and equipment of US$711.8 
million (pre-impairment) at the time of recognition. The Group also recognised 
an impairment reversal of US$21.4 million relating to an IFRS 5 impairment 
adjustment for Williamson as the results for Williamson have been 
re-consolidated in FY2022. For further details of the inputs, assumptions and 
sensitivities in the impairment model, refer to note 15. 
 
Recoverability and ownership of diamond parcel in Tanzania 
 
The Group holds diamond inventory valued at US$12.5 million (30 June 2021: 
US$10.6 million) in the Statement of Financial Position in respect of the 
Williamson mine's confiscated diamond parcel. The diamond inventory parcel was 
written up from the net realisable value of prior periods to cost during the 
current year. The recommencing of operations and the sales tenders at 
Williamson during the Year provided additional information for management to 
assess the value of the diamond parcel and was the basis used to revalue the 
diamond parcel to the lower of cost or net realisable value. During FY 2018, an 
investigation into the Tanzanian diamond sector by a parliamentary committee in 
Tanzania was undertaken to determine if diamond royalty payments were being 
understated. In connection with this, Petra announced on 11 September 2017 that 
a parcel of diamonds (71,654.45 carats) from the Williamson mine in Tanzania 
(owned 75% by Petra and 25% by the Government of the United Republic of 
Tanzania ("GoT")) had been blocked for export to Petra's marketing office in 
Antwerp. 
 
The assessment of the recoverability of the diamond parcel required significant 
judgement. In making such a judgement, the Group considered  the Framework 
Agreement that was signed with the GoT on 13 December 2021, confirmation was 
received from the GoT in FY 2018 that they held the diamond parcel of 71,654.45 
carats, ongoing discussions held with the GoT, an assessment of the internal 
process used for the sale and export of diamonds confirming such process is in 
full compliance with legislation in Tanzania and the Kimberley Process, and 
legal advice received from the Group's in-country attorneys which supports the 
Group's position. 
 
The Framework Agreement which refers to the diamond parcel as the "Government 
Diamond Parcel" sets out that the proceeds from the sale of the Parcel will 
flow to Williamson Diamonds Limited ("WDL"). 
 
While a resolution has not yet been reached with regards to the mechanism to 
sell the parcel of diamonds that was blocked from export, based on the above 
judgements and assessment thereof, management remain confident that based on 
the signed Framework Agreement, and the legal advice received from the Group's 
in-country attorneys, the diamond parcel will be made available for future 
sale, and that WDL will derive future economic benefit from the sales proceeds. 
 
Recoverability of VAT in Tanzania 
 
The Group has VAT receivable of US$2.7 million (30 June 2021: US$0.7 million) 
in respect of the Williamson mine, all of which are past due and have therefore 
been classified, after provision including amounts related to providing for a 
time-value of money inclusive of risk adjustments for various factors, as 
non-current given the potential delays in receipt. 
 
The VAT receivable as at 30 June 2022, can be split into three identifiable 
component time periods as set out below: 
 
US$ million                            VAT     Provision    Written      Carrying 
                                Receivable                      off         value

Pre July 2017 and Post June            8.6         (6.0)          -           2.6 
2020 
 
                                      35.5         (6.0)     (26.9)           2.6 
 
July 2017 to June 2020 
 
A further US$26.9.million (30 June 2021: US$26.9 million) of VAT is receivable 
which relates to VAT under the legislation, effective from July 2017 to 30 June 
2020. 
 
In prior periods management considered the amendment to the VAT legislation for 
the period July 2017 to July 2020 and based on legal advice and the confirmed 
application of the legislation by the TRA considered that the input VAT was not 
recoverable and a full provision was recorded in prior periods.  Further to 
this, the Framework Agreement provisions do not allow for offsetting of these 
historically disputed amounts and as such the full US$26.9 million has been 
written off.  There has been no income statement impact as a result of this 
write-off as the US$26.9 million was fully provided for in prior periods. 
 
Pre July 2017 and Post June 2020 
 
An amount of US$8.6 million (30 June 2021: US$2.6 million) of VAT is receivable 
for the period pre July 2017 and subsequent to 1 July 2020. During FY2021, the 
Group received US$10.0 million in VAT refunds from the Tanzanian Revenue 
Authority in respect of the pre July 2017 period and US$1.2 million was 
disallowed by the Tanzanian Revenue Authority.The Group is considering various 
alternatives in pursuing payment in accordance with legislation. A provision of 
US$6.0 million, given the uncertainty around the timing of receipts of the 
amount outstanding, has been provided for against the US$8.6 million receivable 
resulting in a carrying value of US$2.6 million. 
 
While the remaining pre July 2017 and post 1 July 2020 VAT balance is 
considered receivable, significant uncertainty exists regarding the timing of 
receipt. A discount rate of 14.00% has been applied to the expected cash 
receipts inclusive of estimated country credit risk. A 1% increase in the 
discount rate would increase the provision by US$0.04 million and a one year 
delay would increase the provision by US$0.1 million. 
 
The provision against the VAT balance is US$6.0 million (30 June 2021: US$28.8 
million). The provision relates to US$6.0 million that is recorded against the 
pre July 2017 and post June 2020 amount. The full disputed July 2017 to June 
2020 amount of US$ US$26.9 million, which was fully provided for as at 30 June 
2021 has been written off.  During the Year, an impairment charge of US$4.1 
million (30 June 2021: US$0.7 million (impairment reversal recognised in the 
Loss on discontinued operations)) was recognised in the Consolidated Income 
Statement. 
 
BEE receivables - expected credit loss provision 
 
The Group has applied the expected credit loss impairment model to its BEE 
loans receivable. In determining the extent to which expected credit losses may 
apply, the Group assessed the future free cashflows to be generated by the 
mining operations, based on the current mine plans. In assessing the future 
cashflows, the Group considered the diamond price outlook and the probability 
of reaching an offset agreement. Based on the assessment, the analysis 
generated an expected credit loss charge/reversal totalling US$nil (30 June 
2021: US$5.8 million expected credit loss reversal), comprising of US$nil 
provision charge/reversal in respect of the Cullinan and Finsch Mines (30 June 
2021: US$5.8 million provision comprising of US$6.1 million provision reversal 
in respect of the Cullinan and Finsch Mines and US$0.3 million expected credit 
loss provision in respect of Koffiefontein). 
 
Life of mine and ore reserves and resources 
 
There are numerous risks inherent in estimating ore reserves and resources and 
the associated current life of mine plan. The life of mine plan is the current 
approved management plan for ore extraction that considers specific resources 
and associated capital expenditure. The life of mine plan frequently includes 
less tonnes than the total reserves and resources that are set out in the 
Group's Resource Statement and which management may consider to be economically 
viable and capable of future extraction. 
 
Management must make a number of assumptions when making estimates of reserves 
and resources, including assumptions as to exchange rates, rough diamond and 
other commodity prices, extraction costs, recovery and production rates. Any 
such estimates and assumptions may change as new information becomes available. 
Changes in exchange rates, commodity prices, extraction costs, recovery and 
production rates may change the economic viability of ore reserves and 
resources and may ultimately result in the restatement of the ore reserves and 
resources and potential impairment to the carrying value of the mining assets 
and life of mine plans. 
 
The current life of mine plans are used to determine the ore tonnes and capital 
expenditure in the impairment tests.  Ore reserves and resources, both those 
included in the life of mine and certain additional tonnes which form part of 
reserves and resources considered to be sufficiently certain and economically 
viable, also impact the depreciation of mining assets depreciated on a unit of 
production basis. Ore reserves and resources, outside the current mine plan 
further impact the estimated date of decommissioning and rehabilitation. 
 
Restructuring (30 June 2021) 
 
Transaction costs associated with the restructuring exercise were apportioned 
to the listed debt, equity issued and ZAR banking facilities based on the value 
of each element at the date of restructuring. 
 
Williamson Diamond Mine (30 June 2022) 
 
At 30 June 2021, the accounting treatment of Williamson as an AHFS was in line 
with the conditions required under IFRS 5 Asset Held for Sale and Discontinued 
Operations. 
 
During the current Year, an amended MOU was entered into with Caspian. Per the 
amended MOU, the  Put Option in the Draft MOU was removed and PDL will now sell 
50% less one share in the entity that holds Petra's shares in WDL to Caspian. 
With the amendment to the MOU an assessment was required to determine if 
Williamson still met the asset held for sale criteria or if Williamson (through 
the proposed shareholding structure in the MOU) should be reconsolidated into 
the results of the Group. Consideration was also given on the long-term 
intention of Williamson remaining in the Group for the foreseeable future. 
 
IFRS 10 Consolidated Financial Statements sets out the criteria required for a 
company to consolidate an entity in which it has an investment or interest in. 
A company determines whether it is a parent by assessing whether it controls 
one or more investees, considering all relevant facts, circumstances and rights 
(through voting rights) to variable returns from its involvement with the 
investee and has the ability to affect those returns through its power over the 
investee. 
 
An investor controls an investee if and only if the investor has all of the 
following elements: 
 
  * power over the investee, i.e. the investor has existing rights that give it 
    the ability to direct the relevant activities (the activities that 
    significantly affect the investee's returns); 
  * exposure, or rights, to variable returns from its involvement with the 
    investee; and 
  * the ability to use its power over the investee to affect the amount of the 
    investor's returns. 
 
Management considered the terms of the MOU where the Company will retain a 50% 
plus one share shareholding in the entity that holds Petra's shares in WDL 
which entity will have a right to appoint three directors to WDL's Board, thus 
having the ability to use its power to affect the decision making and the 
strategy of WDL. The Framework Agreement sets out a change in the shareholdings 
in WDL whereby the Government of Tanzania (GoT) shall receive a 16% free carry 
interest, as required by local legislation, while GoT's existing 25% 
shareholding, as well as Petra's existing 75% shareholding will dilute to 21% 
and 63% respectively. The structure of the WDL Board comprises 5 Board members, 
comprising three appointments by the entity that holds Petra's shares in WDL 
and the remaining two Board members being GoT representatives. Petra will, 
through its control of the entity that holds Petra's shares in WDL, therefore 
control WDL. 
 
Based on the Group meeting the requirements of control under IFRS 10 and the 
intention that the Group will not dispose of its remaining interest in 
Williamson in the near future, Williamson is longer considered to be an asset 
held for sale at 30 June 2022 and has been reconsolidated into the Group 
results for the Year refer to note 17 for further detail. 
 
Taxation 
 
The Group operates in South Africa and Tanzania, and accordingly it is subject 
to, and pays annual income taxes under the various income tax regimes in the 
countries in which it operates. From time to time the Group is subject to a 
review of its income tax filings and in connection with such reviews, disputes 
can arise with the taxing authorities over the interpretation or application of 
certain rules to the Group's business conducted within the country involved. 
Management evaluates each of the assessments and recognises a provision based 
on its best estimate of the ultimate resolution of the assessment, through 
either negotiation or through a legal process. 
 
Other key estimates and judgements 
 
In addition to the key estimates and judgements disclosed above, the following 
estimates and judgements have not significantly changed from those disclosed in 
the FY 2021 Annual Report and will be discussed in further detail in the FY 
2022 Annual Report: 
 
  * Provision for rehabilitation 
  * Inventory and inventory stockpile 
  * Depreciation 
  * Pension and post-retirement medical fund schemes 
  * Net investments in foreign operations 
 
3.    DIVIDS 
 
No dividends have been declared in respect of the Year under review (30 June 
2021: US$nil). 
 
4.    SEGMENTAL INFORMATION 
 
Segment information is presented in respect of the Group's operating and 
geographical segments: 
 
Mining - the extraction and sale of rough diamonds from mining operations in 
South Africa and Tanzania. 
 
Corporate - administrative activities in the United Kingdom. 
 
Beneficiation - beneficiation activities in South Africa. 
 
Exploration assets in Botswana were disposed of during FY 2021 via the sale of 
the Group's interest in Sekaka Diamonds Exploration (Pty) Ltd. 
 
Segments are based on the Group's management and internal reporting structure. 
Management reviews the Group's performance by reviewing the results of the 
mining activities in South Africa, Tanzania and reviewing the results of 
reviewing the corporate administration expenses in the United Kingdom. Each 
segment derives, or aims to derive, its revenue from diamond mining and diamond 
sales, except for the corporate and administration cost centre. 
 
Segment results, assets and liabilities include items directly attributable to 
a segment, as well as those that can be allocated on a reasonable basis. 
Segment results are calculated after charging direct mining costs, depreciation 
and other income and expenses. Unallocated items comprise mainly 
interest-earning assets and revenue, interest-bearing borrowings and expenses 
and corporate assets and expenses. Segment capital expenditure is the total 
cost incurred during the year to acquire segment assets that are expected to be 
used for more than one period. Eliminations comprise transactions between Group 
companies that are cancelled on consolidation. The results are not materially 
affected by seasonal variations. Revenues are generated from tenders held in 
South Africa and Antwerp for external customers from various countries, the 
ultimate customers of which are not known to the Group.

1 .The Group predominantly enters into hedge contracts where the risk being 
hedged is the volatility in the South African Rand, Pound Sterling and US 
Dollar exchange rates affecting the proceeds in South African Rand of the 
Group's US Dollar denominated diamond tenders. The fair value of the Group's 
hedges as at the end of the Period are based on Level 2 mark-to-market 
valuations performed by the counterparty financial institutions. The contracts 
are all short dated in nature and mature within the next 12 months. A weakening 
of the South African Rand against the US Dollar from ZAR14.27 (30 June 2021) to 
ZAR16.27 (30 June 2022) resulted in an unrealised loss of US$36.5 million (30 
June 2021: US$77.1 million unrealised gain) comprising a unrealised gain on 
foreign exchange contracts held at Year end of US$0.7 million (30 June 2021: 
US$12.4 million unrealised gain) and losses on inter-group foreign denominated 
loans of US$37.2 million (30 June 2021: US$64.7 million unrealised gain); and a 
net realised foreign exchange gain of US$12.6 million (30 June 2021: US$6.1 
million realised loss) in respect of foreign exchange contracts closed during 
the Year is included in the net finance and expense amount. 
 
2 The loss on substantial modification and gain on extinguishment of Notes in 
FY2021 arose from the Debt Restructuring completed by the Group on 10 March 
2021. 
 
7.    PROPERTY, PLANT AND EQUIPMENT 
 
The net movement in property, plant and equipment for the Period is a decrease 
of US$63.6 million (30 June 2021: US$21.0 million increase). This is primarily 
as a result of: 
 
  * the movement in the US$/ZAR foreign exchange rate resulting in a foreign 
    exchange decrease on Rand based assets of US$83.4 million (30 June 2021: 
    US$136.8 million increase); 
  * an increase in property, plant and equipment from capital expenditure of 
    US$52.2 million (30 June 2021: US$23.8 million), 
  * the transfer of the Williamson assets from non-current assets held for sale 
    of US$31.2 million, net of IFRS 5 adjustment (30 June 2021: US$31.3 million 
    transfer to non-current assets held for sale); 
  * an increase in the rehabilitation asset of US$nil (30 June 2021: US$6.4 
    million (due to the Cullinan Mine's estimated period to decommissioning 
    reducing from 45 years to 25 years reflecting updated scoping studies for 
    future development outside of its current approved mine plan)); 
  * a reversal of IFRS 5 adjustment in respect of the Williamson assets of 
    US$21.4 million (30 June 2021: US$21.4 million impairment charge); 
  * depreciation of US$82.8 million (30 June 2021: US$75.9 million); 
  * the impairment of the Koffiefontein  assets of US$0.3 million (30 June 
    2021: US$17.3 million (Finsch and Koffiefontein)); and 
  * assets of US$1.9 million (30 June 2021: US$0.1 million) disposed of during 
    the Year.

Petra Diamonds US$ Treasury Plc, issued debt securities consisting of US$336.7 
million five-year senior secured second lien loan notes ("Notes"), with a 
maturity date of 8 March 2026. The Notes are guaranteed by the Company and by 
the Group's material subsidiaries and are secured on a second lien basis on the 
assets of the Group's material subsidiaries. The Notes carry a coupon from: 
 
  * 9 March 2021 to 31 December 2022 of 10.50% per annum, which is capitalised 
    to the outstanding principal amount semi-annually in arrears on 31 December 
    and 30 June of each year; 
  * 1 January 2023 to 30 June 2023 of 10.50% per annum on 37.7778% of the 
    aggregate principal amount outstanding, which is capitalised to the 
    outstanding principal amount semi-annually in arrears on 31 December and 30 
    June of each year and 9.75% per annum on 62.2222% of the aggregate 
    principal amount outstanding which is payable in cash semi-annually in 
    arrears on 31 December and 30 June of each year; 
  *  1 July 2023 to 31 December 2025 of 9.75% per annum on the aggregate 
    principal amount outstanding which is payable in cash semi-annually in 
    arrears on 31 December and 30 June of each year; and 
  * 1 January 2026 to 8 March 2026 (final coupon payment) of 9.75% per annum on 
    the aggregate principal amount outstanding which is payable in cash 
 
The costs associated with issuing the Notes of US$20.7 million have been 
capitalised against the principal amount and US$15.2 million remains 
unamortised as at year end (30 June 2021: US$19.4 million). Interest of US$50.3 
million (30 June 2021: US$11.1 million) had been accrued as at 30 June 2022. 
 
Further details about the Notes (including security) have been included in the 
Group's FY 2022 Annual Report. 
 
b) Senior Secured Lender Debt Facilities 
 
During June 2022, the Group restructured its existing banking facilities 
providing for more favourable terms than the Group's current first lien 
facilities and resulting in Absa Corporate and Investment Banking ("Absa") 
becoming the Group's banking partner under the new banking facilities. 
 
A new Revolving Credit Facility ("RCF") with Absa replaces the existing RCF and 
term lending arrangements with the previous South African lender syndicate 
comprising Absa, Nedbank, RMB and NinetyOne. The new terms include, inter alia: 
 
  * improved structure with a single ZAR1 billion RCF replacing the existing 
    amortising term loan of ZAR1.2 billion and the ZAR408.8 million RCF; 
  * more appropriate covenant package resulting in improved headroom and 
    flexibility on the balance sheet; 
  * extended tenure for the RCF with a maturity date of December 2025 and a 
    more usual bullet payment at maturity; and 
  * reduced financing costs with improved margin and commitment fees. The costs 
    associated with restructuring of the banking facilities of US$0.5 million 
    has been expensed in the Consolidated Income Statement under net finance 
    charges. 
 
The revised terms under the RCF are: 
 
  * maturity date December 2025 with a 60 day buffer between the redemption of 
    the Notes and the maturity of the RCF; 
  * to maintain a Net Debt : EBITDA ratio  tested semi-annually on a rolling 
    12-month basis; 
  * to maintain an Interest Cover Ratio tested semi-annually on a rolling 
    12-month basis, which if breached will give rise to an event of default 
    under the new bank facilities; and 
  * interest rate of SA JIBAR + 4.15% per annum (with the margin to be 
    reconsidered annually based on Petra's credit metrics with a view of 
    further optimising the margin to be achieved). 
 
The Group's debt and hedging facilities are detailed in the table below:

¹ The movement in the Kago Diamonds receivable of US$6.9 million (30 June 2021: 
US$38.6 million) is mainly attributable to amounts advanced to Kago Diamonds 
during the Year totalling US$nil (30 June 2021: US$3.8 million), a foreign 
exchange decrease of US$4.1 million (30 June 2021: US$15.4 million increase) 
and offset by the reversal of prior year expected credit loss provision of 
US$nil million (30 June 2021: US$4.2 million reversal) and the loan payable of 
US$nil (30 June 2021: US$62.1 million) by the Group to Kago against the Kago 
receivable. 
 
2 Included in current trade and other receivables are amounts advanced to KEM 
JV in respect of a working capital facility and equipment finance facility of 
US$1.7 million (30 June 2021: US$1.0 million) and the balance of the KEM JV 
purchase consideration of US$nil (30 June 2021: US$0.3 million). During FY2022 
the Group received payments of US$2.5 million (FY 2021 US$nil) from the KEM JV 
as settlement of the outstanding purchase consideration this also resulted in 
an expected credit loss reversal of US$2.9 million (FY2021: US$nil) during the 
Year. The Group has applied the expected credit loss impairment model to the 
KEM JV receivables, taking into account various factors, and the expected 
credit loss was deemed to be US$2.0 million (30 June 2021: US$8.4 million). 
 
3 During the Year, Finsch declared and paid a dividend out of profits generated 
in FY2021 to its shareholders. The BEE partners received a total net dividend 
payment of US$2.5 million comprising Kago US$1.3 million and IPDET US$1.2 
million. 
 
Kago Diamonds is one of the BEE partners which obtained bank financing from 
ABSA, RMB and Ninety-One (the "BEE Lenders") to acquire its interests in the 
Cullinan and Finsch MInes. The Group had previously provided a guarantee to the 
BEE Lenders for repayment of loans advanced to the Group's BEE Partners, 
however during FY2021 as part of the Debt Restructuring, the BEE Partner debt 
facilities were restructured which formed part of the Group's  Term Loan (refer 
to note 8 for further detail). 
 
 11. BEE LOANS RECEIVABLE 
 
BEE Loans Receivable 
 
The non-current BEE loans receivable represents those amounts receivable from 
the Group's BEE Partners (Kago Diamonds and the IPDET) in respect of advances 
historically provided to the Group's BEE Partners to enable them to discharge 
interest and capital commitments under the BEE Lender facilities, advances to 
the BEE Partners to enable trickle payment distributions to both Kago Diamonds 
shareholders and to the beneficiaries of the IPDET (Petra Directors and Senior 
Managers do not qualify as beneficiaries under the IPDET Trust Deed), and 
financing of their interests in the Koffiefontein mine. In addition, US$42.0 
million (30 June 2021: US$45.4 million) has been recorded as part of the gross 
receivable (before expected credit loss provisions) in respect of amounts to be 
reimbursed to the Group in respect of the guarantee under the BEE Lender 
facilities. Judgment was required in determining the extent to which 
reimbursement is applicable based on the terms of the agreements, South African 
legislation and discussions with the BEE partners. 
 
As a result of historical delays in the Cullinan Mine plant ramp-up and the 
Finsch SLC ramp-up, the Group has historically and through the Period elected 
to advance the BEE Partners' funds using Group treasury to enable the BEE 
Partners to service their interest and capital commitments under the BEE Lender 
facilities (refer below). These BEE receivables, including interest raised, 
will be recoverable from the BEE Partners' share of future cashflows from the 
underlying mining operations. 
 
As part of the in principle agreement reached during the Period as part of the 
Restructuring, Petra will assume the BEE Lender facility obligations under the 
terms outlined in note 8. 
 
As part of the Debt Restructuring in FY2021, Petra has assumed the BEE Lender 
facility obligations under the terms outlined in notes 8 and 18. 
 
For detail on expected credit loss provision and reversal associated with the 
BEE loans receivable refer to note 2.

12.  SHARES ISSUED 
 
During the Year, the Company's shareholders approved at the FY2021 Annual 
General Meeting a 50 for 1 Share Consolidation. 
 
Admission of the Company's New Ordinary Shares took place on 29 November 2021. 
As a result of the Share Consolidation, the Company's shares in issue comprise 
of 194,201,785 ordinary shares of 0.05 pence each. 
 
In FY2021, as part of the Restructuring and subsequent to the approval by 
shareholders at a special general meeting held on 13 January 2021, the Company 
allotted 8,844,657,929 Ordinary Shares to the Noteholders valued at US$194.0 
million (comprising Ordinary shares valued at US$12.3 million and share premium 
of US$181.7 million before capitalised costs), based on the share price at 9 
March 2021 (the date upon which all implementation steps for the Debt 
Restructuring were met). The allotment was pursuant to the Debt for Equity 
Conversion, announced on 22 December 2020, which resulted in the Noteholders 
holding 91% of the enlarged share capital of the Company in the following 
proportions: 
 
-      56.0% of the enlarged share capital was issued to all Noteholders, 
including the New Money Noteholders, pro rata to their holdings of existing 
Notes at the close of the Restructuring (to the extent any Noteholder did not 
take up their equity entitlement, such entitlement was allocated to the 
remaining Noteholders who did not opt out of their equity entitlement, on a pro 
rata basis); and 
 
-      35.0% of the enlarged share capital was issued to the New Money 
Noteholders only, pro rata to their contribution of the New Money (to the 
extent any such Noteholders did not take up their equity entitlement, such 
entitlement was allocated to the remaining Noteholders who contributed to the 
New Money and who did not opt out of their equity entitlements, on a pro rata 
basis). 
 
As a consequence of the Debt for Equity Conversion, 9% of the Company's 
enlarged share capital remains with the previous shareholders (subject to 
dilution as a result of standard management equity incentive arrangements). The 
costs associated with the allotment of the new ordinary shares of US$12.3 
million were capitalised against share premium. For additional information 
regarding the Restructuring refer to note 18.

15.   IMPAIRMENT CHARGE 
 
The current market conditions in the global rough diamond market, volatility of 
and variability in product mix are all factors impacting the rough diamond 
prices achieved by Petra during the Year, resulting in management taking a 
critical review of the Group's business models and operational assets. The 
carrying amounts of the Group's assets are reviewed at each reporting date to 
determine whether there is any indication of impairment. If there is any 
indication that an asset may be further impaired or an impairment reversal may 
apply, its recoverable amount is estimated. The recoverable amount is 
determined on a fair value less cost to develop basis. 
 
The operations of the Cullinan, Finsch, Koffiefontein and Williamson Mines are 
held at recoverable value as a result of FY2021 impairments. During the Year 
under review, the Group reviewed the carrying value of its investments, loan 
receivables and operational assets for indicators of impairment. Following the 
assessment, no further impairment of property, plant and equipment was 
considered appropriate for the Cullinan, Finsch and Williamson Mines, nor was 
any impairment reversal considered appropriate in the current Year. The Group 
recognised an asset level impairment charge of US$0.3 million being 
managements' estimate of the decrease in the value of the Koffiefontein assets. 
The Group also reversed a Group level impairment charge relating to Williamson, 
previously recognised under IFRS 5, of US$21.4 million as Williamson is no 
longer considered an asset held for sale. 
 
The Group recognised a consolidated income statement charge of US$4.1 million 
comprising management's estimate of the recoverability of the Tanzania VAT 
receivable, an impairment charge of US$0.3 million related to other receivables 
and an impairment reversal of US$2.9 million of the KEM JV receivable.

30 June 2021 
 
The operations of the Cullinan, Finsch and Koffiefontein Mines were held at 
recoverable value as a result of FY 2020 impairments. During FY 2021, the Group 
reviewed the carrying value of its investments, loan receivables and 
operational assets for indicators of impairment. Following the assessment, 
impairment of property, plant and equipment was considered appropriate for 
Finsch and Koffiefontein. No impairment was considered necessary for the 
Cullinan Mine, nor was any impairment reversal considered appropriate in the 
current year. The Group recognised a consolidated income statement charge of 
US$17.3 million being the amount required to write down management's estimate 
of recoverable value of the Finsch and Koffiefontein assets. Williamson was 
classified as Held for Sale as at 30 June 2021 (refer to note 17).

Cullinan, Finsch, Koffiefontein and Williamson impairment considerations and 
assumptions 
 
The Group performs impairment testing on an annual basis of all operations and 
when there are potential indicators of impairment. The impairment testing 
performed resulted in impairments of the Koffiefontein and Williamson assets. 
The key assumptions used in determining the recoverable value calculations, 
determined on fair value less cost to develop basis, are listed in the table 
below: 
 
Group assumptions for 30 June 2022 and 30 June 2021: 
 
Key assumptions            Explanation 
 
Current mine plan and      Economically recoverable reserves and resources are based on 
recoverable value of       management's expectations based on the availability of reserves 
reserves and resources     and resources at mine sites and technical studies undertaken in 
                           house and by third party specialists. 
                           The end of life of mine based on current mine plans for the 
                           operations are as follows: 
                           Cullinan Mine: FY 2031 (FY 2021: FY 2031) 
                           Finsch: FY 2030 (FY 2021: FY 2030) 
                           Koffiefontein: FY 2025 ( (FY 2021: FY 2023) 
                           Williamson: FY 2030 
                           Resources remaining after the current mine plans have not been 
                           included in impairment testing for the operations. 
 
Current mine plan reserves Cullinan Mine: Current mine plan over the next nine years; 
and resources              total resource processed 36.4 Mt (FY 2021: Current mine plan 
                           over the next nine years; total resource processed 38.6 Mt). 
 
                           Finsch: Current mine plan over the next eight years; total 
                           resource processed 23.2 Mt (FY 2021: Current mine plan over the 
                           next nine years; total resource processed 26.8 Mt). 
 
                           Koffiefontein: Current mine plan over the next three years; 
                           total resource processed 1.9 Mt (FY 2021: Current mine plan 
                           over the next three years; total resource processed 2.2 Mt). 
 
                           Williamson: Current mine plan over the next eight years, total 
                           resource processed 43.3 Mt (FY2021:  Williamson was on care and 
                           maintenance). 
 
Current mine plans -       Management has estimated the timing and quantum of the capital 
capital expenditure        expenditure based on the Group's current mine plans for each 
                           operation. There is no inclusion of capital expenditure to 
                           enhance the asset beyond exploitation of the current mine plan 
                           orebody. 
 
Residual Value             Cullinan Mine: Management included a residual value of 
                           property, plant and equipment to be used beyond the current 
                           mine plan, given the significant resource base estimated to be 
                           available at the end of the current mine plan. 
                           No residual values were included in the impairment assessments 
                           of the other mining operations. 
 
Diamond prices             The diamond prices used in the impairment test have been set 
                           with reference to recently achieved pricing and market trends, 
                           and long-term diamond price escalators are informed by industry 
                           views of long-term market supply/demand fundamentals. Given the 
                           current market uncertainty, the assessment of short-term 
                           diamond prices and the rate and extent of pricing recovery, 
                           together with the longer-term pricing escalators, represented a 
                           critical judgement 
 
                           The 30 June 2022 impairment testing models starting price 
                           assumptions have been adjusted to reflect the improved pricing 
                           achieved during the Year when compared to the 30 June 2021 
                           impairment models. Diamond prices (excluding Exceptional 
                           Stones) have been assumed to remain unchanged during FY2023, 
                           then increase by 3.9% from FY2024 onwards. The long-term models 
                           incorporate normalised diamond price escalation of 1.9% above a 
                           long-term US inflation rate of 2.0% per annum from FY 2024 to 
                           FY 2030. Estimates for the contribution of Exceptional Diamonds 
                           sold for more than US$5.0 million each are determined with 
                           reference to historical trends. Based on the historical trends, 
                           management have increased the contribution from Exceptional 
                           Stones at the Cullinan Mine from US$25.0 million to US$35.0 
                           million per annum. 
 
                           The 30 June 2021 impairment testing models starting price 
                           assumptions have been updated to reflect the improved pricing 
                           achieved during the Year when compared to the 30 June 2020 
                           impairment models. Diamond prices have been assumed to increase 
                           from FY 2022 and then 4.4% from FY 2024, returning to pricing 
                           levels achieved before the impact of COVID-19, representing an 
                           increase of 25-30% from pricing achieved at the lowest point 
                           during FY2020. The long-term models incorporate normalised 
                           diamond price escalation of 1.9% above a long-term US inflation 
                           rate of 2.5% per annum from FY 2025 to FY 2030. Estimates for 
                           the contribution of Exceptional Diamonds sold for more than 
                           US$5.0 million each are determined with reference to historical 
                           trends. 
 
Discount rate              A ZAR discount rate of 13.0% (30 June 2021: 12.0%) was used for 
                           the South African operations in and a USD discount rate of 
                           14.00% (30 June 2021: 13.50%) for Williamson. Discount rates 
                           calculated based on a nominal weighted average cost of capital 
                           including the effect of factors such as market risk and country 
                           risk as at the Year end. USD and ZAR discount rates are applied 
                           based on respective functional currency of the cash generating 
                           unit. As Williamson was held for sale as at 30 June 2021, the 
                           discount rate was applied to cashflows expected from a disposal 
                           transaction. 
 
Cost inflation rate        Long-term inflation rates of 3.5%-7.5% (30 June 2021: 
                           3.5%-7.8%) above the long-term US$ inflation rate were used for 
                           opex and capex escalators. Management have taken into account 
                           the current short-term pressures in the inflation environment 
                           and the impact on Opex and capex costs, allowing for the 
                           inflation rate to normalise over the longer-term. 
 
Exchange rates             Exchange rates are estimated based on an assessment of current 
                           market fundamentals and long-term expectations. The US$/ZAR 
                           exchange rate range used for all South African operations 
                           commenced at ZAR16.04 (30 June 2021: ZAR14.50) for FY2023 
                           reflecting the current volatility, inflationary pressures and 
                           quantitative tightening by Central banks, and ZAR16.24 for 
                           FY2024  and thereafter devaluing at 3.5% per annum. Given the 
                           volatility in the USD/ZAR exchange rate and the current levels 
                           of economic uncertainty, the determination of the exchange rate 
                           assumptions required significant judgement. 
 
Valuation basis            Discounted present value of future cash flows. 
 
Williamson                 During the Year, Williamson recommenced production. For 
                           impairment testing at Williamson, management have used the 
                           above assumptions. 
 
                           During FY2021, Williamson was classified as an asset held for 
                           sale, for further detail refer to note 17.

16.           DISPOSAL OF OPERATION (30 June 2021) 
 
 a. Disposal of Botswana (exploration) 
 
During FY 2021, the Company disposed of its exploration assets in Botswana via 
the sale of 100% of its holding in Sekaka Diamonds Exploration (Pty) Limited 
("Sekaka") to Botswana Diamonds PLC for a total consideration of US$300,000 and 
a 5% royalty on future diamond revenues should any of the prospects within the 
exploration licences be brought into production. Refer to note 36 of FY2021 
Annual Report for details. 
 
The profit on disposal of subsidiary of US$14.7 million comprises a US$0.3 
million disposal consideration, net profit of US$1.3 million for the Period 1 
July 2020 to the 30 November 2020 disposal date, and the recycling of the 
foreign currency translation reserve of US$13.3 million, offset by a net asset 
disposal amount of US$0.2 million. 
 
17.           WILLIAMSON 
 
 a. Framework Agreement 
 
On 13 December 2021, the Company signed an agreement in principle with the 
Government of Tanzania relating to the Williamson operations. Williamson 
resumed operations and sales during the Year, having been on care and 
maintenance since April 2020. 
 
The Framework Agreement provides for a capital restructuring of the Williamson 
Diamonds Limited ("WDL"), the entity that owns the Williamson Mine, including 
the 16% free carried interest that the Government of Tanzania is entitled to 
receive in WDL and its shareholder loans under Section 10 of the Tanzanian 
Mining Act, 2017 and Regulation 10 of the Tanzanian Mining (State 
Participation) Regulations, 2020. The capital restructuring will include: 
 
  * a WDL share issue with the effect of reducing Petra's indirect shareholding 
    from 75% to 63% and consequently increasing the Government of Tanzania's 
    shareholding from 25% to 37%; 
  * a contribution to the Government of Tanzania of 16% of the principal 
    outstanding value of the Group's shareholder loans payable by WDL, with the 
    remaining 84% of such principal outstanding loans continuing to be owed to 
    the Group; and 
  * the transfer of the WDL shares held by the Group to another member of the 
    Petra Group (either Petra itself or a special purpose subsidiary). Petra 
    have registered Mwadui Mining Holdings Ltd, a subsidiary registered in the 
    United Kingdom, for this purpose. 
 
With respect to the reorganisation of the parties' legal interests in WDL, the 
Framework Agreement also provides for an overall 55:45 economic benefit sharing 
ratio between the Government of Tanzania and Petra in relation to future 
economic benefits from the Williamson Mine. This arrangement is intended to 
capture the parties' entitlements as shareholders as well as, with respect to 
the Government of Tanzania, the revenue it collects from WDL arising from 
taxes, royalties, duties, fees and other fiscal levies ("Government Imposed 
Charges"). The Framework Agreement also provides that WDL shall be entitled to 
off-set its undisputed unpaid and overdue VAT receivables against future 
Government Imposed Charges, whereby such Government Imposed Charges will be 
off-set and treated as paid for the purposes of the economic benefit sharing 
ratio. 
 
The Framework Agreement provides that Petra and the Government of Tanzania will 
provide financial assistance for the restart of operations at the Williamson 
Mine. The Government of Tanzania has agreed to allocate the sales proceeds of 
the 71,654.45 carat diamond parcel from the Williamson Mine that was previously 
confiscated and blocked for export. The original value of this parcel was 
assessed in September 2017 at approximately US$15 million, as previously 
disclosed, although Petra has not had the parcel independently valued. 
 
The Framework Agreement records an important US$20.0 million settlement between 
the parties concerning long-standing historic disputes with the Government of 
Tanzania. In FY2021, as at 30 June 2021 the Group raised a provision of US$19.5 
million (adjusted for time-value of money) in respect of the aforementioned 
settlement. This settlement payment shall be made in instalments, with the 
first instalment of US$5.0 million to be paid when the Framework Agreement 
becomes effective and upon receipt of proceeds by WDL from the sale of the 
confiscated diamond parcel.  The subsequent annual instalments of the 
settlement amount are to be made annually at amounts as determined by WDL's 
board of directors. 
 
The Framework Agreement is subject to a number of conditions, including 
Tanzanian regulatory approvals and the consent of Petra's South African lender 
group, and is therefore not yet effective as at 30 June 2022. Petra is entering 
into the Framework Agreement with the Government of Tanzania in the latter's 
capacity principally as a regulator and collector of taxes in Tanzania. 
However, the Government of Tanzania is also a related party to Petra for the 
purposes of the UK Listing Rules, due to the Government's shareholding in WDL. 
The Framework Agreement could not become legally binding on the parties until 
approval was obtained from Petra's shareholders. On 9 February 2022, Petra 
received shareholder approval of the Framework Agreement. Notwithstanding, the 
Government of Tanzania's right to a 16% free carried interest under the 
Tanzanian Mining Act, 2017 is an entitlement as a matter of Tanzanian law, and 
is not of itself ultimately subject to any approval or condition in any 
respect. Accordingly, Petra acknowledges that arrangements to reflect this will 
need to be implemented regardless of the Framework Agreement becoming 
effective. 
 
                 Memorandum of Understanding with Caspian Limited ("MOU") 
 
On 15 December 2021, the Company announced that it had signed a non-binding 
Memorandum of Understanding ("MoU") to sell 50% less one share of the entity 
that holds the Group's shareholding in Williamson Diamonds Limited ("WDL"), 
along with a pro rata portion of shareholder loans owed by WDL, to Caspian 
Limited or its nominee ("Caspian") for a total consideration of US$15.0 
million. Caspian is the long-term technical services contractor at the 
Williamson Mine. 
 
Upon completion of the transactions contemplated by the MoU and the capital 
restructuring in the aforementioned Framework Agreement becoming effective, 
Petra and Caspian will each indirectly hold a 31.5% stake in WDL but Petra 
retains a controlling interest in Williamson. 
 
Caspian's purchase will be funded through the settlement of US$11.1 million of 
past technical services payments owed by WDL to Caspian, including services 
rendered during the recent restart of operations following the care and 
maintenance period, with the remaining amount being funded by Caspian rendering 
US$3.9 million of technical services to WDL in order to ramp-up operations at 
the Williamson Mine. 
 
The sale of the 50% less 1 share stake in the entity that holds Petra's shares 
in WDL is subject to the parties obtaining all necessary Governmental, 
regulatory and lender approvals, including approvals from the Tanzanian Mining 
Commission, the Tanzanian Fair Competition Commission and The Bank of Tanzania, 
and a binding ruling from the Tanzania Revenue Authority on the tax treatment 
of the transaction.  The parties are seeking to obtain such approvals by the 
end of Q1 FY 2023. 
 
As at 30 June 2021, the criteria for classification as Asset Held for sale was 
met. Refer to (b) below for FY2021 disclosures). Subsequently, the signing of 
the MOU will result in Petra retaining its controlling interest in WDL and will 
see Petra consolidating WDL's operating and financial results, with an 
appropriate recognition of non-controlling interest attributable to both 
Caspian and the Government of Tanzania. As neither agreement mentioned above is 
effective as at 30 June 2022, WDL has been consolidated in the same proportions 
as prior to its Held for Sale classification being 75% Petra and 25% Government 
of Tanzania. 
 
 a. Asset Held for Sale (30 June 2021) 
 
As at 30 June 2021, the assets and liabilities of the Williamson operation 
(being Petra's 75.0% interest) were classified as held for sale in the 
Statement of Financial Position at 30 June 2021, in accordance with IFRS 5. The 
financial results of the Williamson operation for FY2021 were disclosed in the 
Consolidated Income Statement in Loss on discontinued operation. These have 
been restated for the year ending 30 June 2022. The Williamson mining operation 
is a separate operating segment for the purposes of the Group's segmental 
reporting.

The US$21.4 million impairment loss recorded on the Williamson assets 
represented the difference between the assets measured at the lower of their 
carrying amount and fair value less costs to sell considering the best 
available information at the present time with reference to ongoing discussions 
with a potential investor. The impairment charge of US$21.4 million was 
recognised to reduce assets of Williamson to equal the fair value less costs to 
sell.
