           Interim results for the six months ended 31 December 2022 
 
H1 in line with expectations; annual production on track to increase by c.1 Mct 
in FY 2025 
 
Petra Diamonds Limited ("Petra" or the "Company" or the "Group") announces its 
unaudited interim results for the six months ended 31 December 2022 (the 
"Period", "H1 FY 2023", or "H1"). 
 
Richard Duffy, Chief Executive Officer at Petra Diamonds commented: 
 
"Petra's new culture and ongoing focus on continuous improvement through our 
operating model has enabled the Company to respond swiftly and efficiently to 
the operational challenges experienced in H1 FY 2023. 
 
We are optimistic that the fundamentals of the diamond market will continue to 
support prices, with demand for luxury goods remaining robust in the USA, 
notwithstanding recent economic volatility. We also expect that the ending of 
lock-down restrictions in China will benefit diamond pricing in the near to 
medium term. 
 
We remain on track to meet recent production guidance, while our cost guidance 
remains largely unchanged despite inflationary pressures as a result of our 
ongoing focus on costs, supported by a weaker Rand. Both the Finsch & Cullinan 
Mines have a significant resource base giving them potential for long lives, 
and our projects at both mines continue to progress in line with expectations. 
As a result, our guidance shows annual production increasing by c.1 million 
carats from 2.8 million carats in FY 2023 to 3.6 - 3.9 million carats in FY 
2025. Production will be further boosted from the recently approved C-Cut 
extension at the Cullinan Mine, set to deliver a total of 2.3 million 
additional carats from FY 2025 through to FY 2033. 
 
At Williamson, we have made considerable progress in addressing the social and 
environmental impact of the tailings storage facility wall breach. The 
necessary permits are being put in place, with production anticipated to resume 
during Q1 FY 2024. Ahead of this resumption, maintenance is being accelerated 
and waste stripping is being carried out to construct the interim tailings 
storage facility and to enable an efficient ramp-up in production. 
 
Koffiefontein has been loss making for a number of years and incurred an 
operating loss of US$8.7 million in H1. We are taking important steps towards 
responsible closure in discussion with all relevant stakeholders. 
 
Revenue for the half year decreased from US$264.7 million in H1 FY 2022 to 
US$212.1 million, with the strength of our product mix and an increase in 
like-for-like diamond prices of 12.6% helping to offset lower production and no 
contribution from Exceptional Stones[1] (H1 FY 2022: US$77.9 million). 
 
Post period-end, two blue diamonds recovered from the Cullinan Mine, including 
an Exceptional Stone, were sold into partnership. The 17.4 and 10.4 carat gem 
quality blue diamonds were sold for US$7 million and US$2 million respectively. 
We will share equally in any upside on the sale of the stones once cut and 
polished, extending our partnership approach on selected diamonds." 
 
[1] Petra classifies "Exceptional Stones" as rough diamonds which sell for US$5 
million or more each

Note 1: For all non-GAAP measures refer to the Summary of Results table within 
the Financial Results section below. 
 
  * Revenue amounted to US$212.1 million (H1 FY 2022: US$264.7 million), 
    including US$1.4 million from Petra's realised profit share from 
    partnership stones 
  * The average realised price per carat in H1 FY 2023 was US$160/ct down 3% to 
    US$166 in H1 FY 2022 and US$165/ct for FY 2022 
  * Adjusted mining and processing costs remained within expectations despite 
    inflationary pressures. The increase was largely attributable to diamond 
    inventory movement while cash on mine cost remained largely flat 
  * Adjusted EBITDA 49% lower YoY, due to the lack of contribution from 
    Exceptional Stones (US$64 million at Cullinan Mine and US$13.9 million at 
    Williamson Mine in the prior period), together with lower sales volumes 
  * Basic loss per share from continuing operations of USc12.23 per share and 
    USc0.91 on an adjusted basis after accounting for non-controlling interests 
  * Capex increased to US$51.9 million (H1 FY 2022: US$ 16.7 million) largely 
    due to the planned capital expenditure relating to expansion projects at 
    the Cullinan and Finsch Mines, coupled with accelerated  equipment 
    replacement at Finsch 
  * Operational free cash flow down to US$11.7 million on the back of reduced 
    sales and the planned increase in capital expenditure relating to expansion 
    projects 
  * Further strengthening of the Balance Sheet: 
      + Unrestricted cash decreased by US$141.5 million to US$130.4 million 
        following the successful repurchase of Loan Notes totaling US$146.1 
        million 
      + Consolidated net debt increased to US$90.2 million from US$40.6 million 
        as at 30 June 2022, with Consolidated net debt : Adjusted EBITDA at 
        0.47x compared with 0.15x at 30 June 2022

Updates on Williamson 
 
Tailings storage facility (TSF) wall breach 
 
  * Financial: As a result of the TSF wall breach, a US$5.9 million remediation 
    charge is reflected in the profit and loss statement (after Adjusted NPAT). 
    Approximately US$1.5 million of this amount was incurred up to 31 December 
    2022, with the balance accrued for at period-end and is expected to be 
    incurred during H2 FY 2023. 
 
  * Environment, Local Community, Technical and Production: We continue to make 
    good progress with regards to the environmental, social and economic impact 
    evaluation and remediation process, with humanitarian relief remaining in 
    place for those affected. The geotechnical evaluation to establish the root 
    cause of the subsidence that caused the breach is underway, with operations 
    anticipated to restart using an interim TSF in Q1 FY 2024. More detailed 
    information regarding these processes and assessments is available on our 
    website: https://www.petradiamonds.com/our-operations/our-mines/williamson/ 
    tailings-storage-facility-breach/ 
 
 Blocked diamond parcel 
 
  * Under the Framework Agreement entered into by the Government of Tanzania 
    ("GoT"), the Company and Williamson Diamonds Limited ("WDL") in December 
    2021, the GoT agreed to allocate the proceeds of the confiscated diamond 
    parcel of 71,654.45 carats ("Blocked Parcel") to WDL. It has come to our 
    attention that a portion of the Blocked Parcel has recently been sold. We 
    are engaging with GoT to confirm the application of the proceeds. More 
    information on the history of the Blocked Parcel can be found on our 
    website:   Petra Diamonds | Blocked Diamond Parcel - Petra Diamonds 
 
Independent Grievance Mechanism and community projects at Williamson 
 
  * The Independent Grievance Mechanism (IGM), a non-judicial process to 
    address the historical allegations of human rights abuses at Williamson 
    became operational in November 2022 and is now in its pilot phase. The 
    pilot phase will involve the award of remedy to those determined to have 
    suffered severe human rights impacts whilst allowing for the IGM's systems 
    and procedures to be further developed to take into account the learnings 
    of the pilot phase. More detailed information on the IGM and the 
    Restorative Justice Projects being put in place to provide sustainable 
    benefits to the communities located around the mine can be found on our 
    website: https://www.petradiamonds.com/our-operations/our-mines/williamson/ 
    allegations-of-humanrights-abuses-at-the-williamson-mine/ 
 
Outlook 
 
Actions taken to strengthen our business and improve cash flow generation, 
together with our capital discipline, means that Petra is well placed to take 
advantage of the supportive diamond market fundamentals. Our projects remain on 
track to deliver a c.1Mct annual increase in FY 2025, with work commencing on 
the C-cut extension to unlock a further 2.3Mct from FY 2025 through to FY 2033, 
as we continue to develop the long term potential of our resource base. We 
remain confident that we will continue to generate sufficient cash to fund 
capex and allow further deleveraging. The Company will consider the payment of 
a FY 2023 dividend when finalising its year end results.

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, 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.      Adjusted profit from mining activities is revenue less adjusted mining 
and processing costs plus other direct income. 
 
3.      Adjusted corporate overhead is corporate overhead expenditure less 
corporate depreciation, tender offer transaction costs and share-based expense. 
 
4.      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), recovery 
of fees relating to investigation and settlement of human rights abuse claims, 
Williamson tailings facility remediation costs and accelerated depreciation and 
unrealised foreign exchange gains and (losses). 
 
5.      Tax expense is the tax expense for the Period excluding taxation credit 
on unrealised foreign exchange gain/(loss) generated during the Period; such 
exclusion more accurately reflects resultant adjusted net profit. 
 
6.      Adjusted net profit after tax is net profit after tax stated before 
impairment (charge)/reversal, Williamson tailings facility remediation costs 
and accelerated depreciation, recovery of fees relating to investigation and 
settlement of human rights abuse claims net unrealised foreign exchange gains 
and losses, and excluding taxation credit on net unrealised foreign exchange 
gains and losses and excluding taxation credit on impairment charge. 
 
7.      Impairment charge of US$3.8 million (30 June 2022: US$19.6 million 
reversal and 31 December 2021: US$0.1 million reversal) was due to the Group's 
impairment review of its operations and other receivables. Refer to note 15 for 
further details. 
 
8.      Transaction costs and acceleration of unamortised costs on partial 
redemption of Notes comprise transaction costs of US$0.8 million included 
within Corporate expenditure (refer to note 5) and US$8.2 million in respect of 
the redemption premium and acceleration of unamortised costs included within 
Finance expense (refer to note 6). 
 
9.      Adjusted EPS is stated before impairment charge, gain on extinguishment 
of Notes net of unamortised costs,  acceleration of unamortised costs on Notes, 
Williamson tailings facility remediation costs and accelerated depreciation, 
recovery of fees relating to investigation and settlement of human rights abuse 
claims,  and net unrealised foreign exchange gains and losses, and excluding 
taxation credit on net unrealised foreign exchange gains and losses. 
 
10.    The 2026 US$336.7 million loan notes, originally issued following the 
capital restructuring (the "Restructuring") completed during March 2021, have a 
carrying value of US$241.7 million (30 June 2022: US$366.2 million) which 
represents the outstanding principal amount of US$210.2 million (after the 
early participation phase of the debt tender offers as announced in September 
and October 2022) plus US$43.0 million of accrued interest and net of 
unamortised transaction costs capitalised of US$11.5 million. Refer to Note 8 
for further detail. 
 
11.    Bank loans and borrowings represent the Group's ZAR1 billion (US$58.8 
million) revolving credit facility which remains undrawn and available. 
 
During the FY2022, 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). 
 
12.    Consolidated Net Debt is bank loans and borrowings plus loan notes, less 
cash and less diamond debtors. 
 
13.    Operational free cashflow is defined as cash generated from operations 
less cash outflows on the acquisition of property, plant and equipment. 
 
14.    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. During February 2023, it has come to 
our attention that a portion of the Blocked Parcel has been sold. We are 
engaging with GoT to confirm the application of the proceeds. 
 
Revenue 
 
H1 FY 2023 amounted to US$212.1 million (H1 FY 2022: US$264.7 million), 
comprising revenue from rough diamond sales of US$210.7 million (H1 FY 2022: 
US$264.7 million) and additional revenue from profit share agreements of US$1.4 
million (H1 FY 2022: US$nil). 
 
H1 FY 2023 revenue from rough diamond sales decreased 20% to US$210.7 million 
(H1 FY 2022: US$264.7 million) as result of no sales of Exceptional Stones 
during the Period (H1 FY 2022 US$77.9 million), lower volumes sold largely 
owing to reduced tonnages at Finsch and lower grades at the Cullinan Mine, 
which was partially offset by improved product mix, largely at the Cullinan 
Mine, and a 12.6% increase in like-for-like diamond prices. 
 
Mining and processing costs 
 
The mining and processing costs for H1 FY 2023 comprised on-mine cash costs as 
well as other operational expenses. A breakdown of the total mining and 
processing costs for the Period 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.     Remediation costs comprise costs involved in establishing the root cause 
of the failure, humanitarian relief to the affected community, livelihood- and 
environmental restoration and costs to repair. 
 
4.     Includes US$5.2 million of accelerated depreciation at Williamson 
relating to assets damaged in the TSF failure and amortisation of right-of-use 
assets under IFRS 16 of US$1.7 million (H1 FY2022: US$0.6 million and FY 2022: 
US$2.3 million) and excludes corporate / administration. 
 
On-mine cash costs reduced by US$1.4 million (1.1%) compared to H1 FY 2022 and 
in line with expectations, due to: 
 
  * The effect of translating ZAR denominated costs at the South African 
    operations at a weaker ZAR/USD average exchange rate (12.4% decrease) 
  * Lower production volumes at South African operations (5.0% decrease) 
  * Other cost savings, including reduction in on-mine costs due to 
    centralisation (3.4% decrease) 
 
Offset by: 
 
  * Increase in Williamson cash costs compared to a lower prior year base, 
    following restart post-care and maintenance in H1 FY22 (12.0% increase) 
  * Inflationary increases (6.9% increase) 
  * Above-inflation increases associated with electricity costs (0.8% increase) 
 
Royalties increased to US$3.7 million (H1 FY 2022: US$3.4 million) driven by 
increased revenues from Williamson compared to the prior period. 
 
Adjusted profit from mining activities 
 
Adjusted profit from mining activities decreased 47% to US$82.3 million (H1 FY 
2022: US$155.2 million), mainly due to no sales of Exceptional Stones during 
the Period, the impact of lower volumes at the Cullinan and Finsch Mines, and 
increased costs at Williamson being in production for a period of almost five 
months (prior to the tailings storage facility failure when operations at the 
mine ceased) compared to three months in the comparative period. 
 
Adjusted corporate overhead - general and administration 
 
Corporate overhead (before depreciation and share based payments) increased to 
US$5.4 million for the Period (H1 FY 2022: US$4.9 million) mainly attributable 
to the increase in corporate governance structures and costs associated with 
the Williamson IGM process during the Period. 
 
Adjusted EBITDA 
 
Adjusted EBITDA, being profit from mining activities less adjusted corporate 
overhead, decreased 49% to US$77.4 million (H1 FY 2022 US$150.9 million), 
representing an adjusted EBITDA margin of 36% (H1 FY 2022: 57%) driven by the 
lower production, increased mining costs and zero contribution from Exceptional 
Stones. 
 
Depreciation and amortisation 
 
Depreciation and amortisation for the Period of US$42.4 million (H1 FY 2022: 
US$43.1 million), decreased due to lower production and a weaking ZAR/USD, 
offset by the inclusion of accelerated depreciation of US$5.2 million 
attributable to the assets written down at Williamson as a result of the 
tailings storage facility failure. 
 
Impairment reversal / charge 
 
As a result of the impairment reviews carried out at the Group's operating 
assets and other receivables during the Period, an overall net impairment 
charge of US$3.8 million (H1 FY 2022: US$0.1 million impairment reversal) was 
recognised, comprising: 
 
US$ million                                                   H1 FY H1 FY 2022 
                                                               2023

Impairment reviews carried out at the Cullinan, Finsch and Williamson Mines did 
not result in an impairment charge or reversal for operational assets during 
the Period (H1 FY 2022: US$nil). Asset level impairment at Koffiefontein 
amounted to US$0.3 million (H1 FY 2022: US$0.3 million), compared to the 
Group's carrying value of property, plant and equipment of US$615.3 million (H1 
FY 2022: US$624.0 million) pre-impairment. 
 
During the Period, an impairment charge of US$3.5 million (H1 FY 2022: US$0.4 
million) relating to VAT receivable at Williamson was recognised in the 
Consolidated Income Statement. 
 
Net financial expense 
 
Net financial expense of US$27.0 million (H1 FY 2022: US$44.9 million) 
comprises: 
 
US$ million                                               H1 FY 2023  H1 FY 2022

Tax credit / charge 
 
The tax charge of US$14.2 million (H1 FY 2022: US$13.6 million) comprised a 
deferred tax charge of US$14.0 million (H1 FY 2022: US$24.3 million) and a net 
current tax charge of US$0.2 million (H1 FY 2022: US$nil). The tax charge of 
US$14.2 million (H1 FY 2022: US$13.6 million) comprised a deferred tax charge 
of US$14.2 million (H1 FY 2022: US$24.3 million) in respect of the utilisation 
of capital allowances at the Cullinan Mine, Finsch and Williamson Mines and 
US$0.2 million deferred tax credit (H1 FY2022: US$11.1 million) relating to 
unrealised foreign exchange losses during the Period, which reduced existing 
deferred tax liabilities, with an income tax charge of US$0.2 million at 
Williamson for the Period (H1 FY 2021: US$0.4 million at Finsch). 
 
The current period effective tax rate is higher than the South African tax rate 
of 27% (the Group's primary tax paying jurisdiction) primarily due to foreign 
exchange losses and permanent differences as a result of the Koffiefontein 
impairment and loss making companies (within the Group) where deferred tax 
assets on operating losses are not recognised, which when consolidated reduces 
the Group's overall profit before tax resulting in an increased effective tax 
rate. 
 
Williamson Tailings Storage Facility (TSF) 
 
On 7 November 2022, the TSF wall at the Williamson mine was breached, resulting 
in flooding away from the pit which has extended into certain areas outside of 
the mine lease area. As a result, remediation costs relating to the incident 
have been incurred during the Period and additional costs will be incurred 
going forward. The remediation costs comprise establishing the root cause of 
the failure, humanitarian relief to the affected community, livelihood and 
environmental restoration and costs to repair. 
 
In H1 FY 2023, US$1.5 million of costs have been incurred and a further US$4.4 
million of costs, comprising management's best estimate based on the current 
information available, has been provided for ongoing remediation costs. 
 
In addition, US$5.2 million of accelerated depreciation was recognised in the 
Period to fully write down assets damaged in the TSF breach. 
 
Earnings per share 
 
Basic loss per share from continuing operations of USc12.23 was recorded (H1 FY 
2022: USc22.29 profit). 
 
Adjusted loss per share from continuing operations (adjusted for impairment 
charges, transaction costs and accelerated unamortised costs, taxation credit 
on net unrealised foreign exchange losses and net unrealised foreign exchange 
gains and losses) of USc0.91 was recorded (H1 FY 2022: USc29.01 profit 
(adjusted for impairment charges, taxation charge on net unrealised foreign 
exchange gains and net unrealised foreign exchange gains and losses)). 
 
Operational free cash flow 
 
During the Period, operational free cash flow of US$11.7 million (H1 FY 2022: 
US$122.4 million) reflects the impact from an increase in capital expenditure 
of US$32.4 million and a decrease in revenue from Exceptional Stones of US$89.1 
million. This cash flow performance was further impacted by: 
 
  * US$6.4 million outflow (H1 FY 2022: US$4.8 million inflow) of net realised 
    foreign exchange gains/(losses) and cash finance expenses net of finance 
    income; 
  * US$2.7 million dividend paid to BEE partners (H1 FY 2022: US$3.5 million). 
 
Cash and Diamond Debtors 
 
As at 31 December 2022, Petra had cash at bank of US$146.6 million (H1 FY 2022: 
US$272.3 million). Of these cash balances, US$130.4 million was held as 
unrestricted cash (H1 FY 2022: US$256.7 million), US$15.4 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) (H1 FY 2022: 
US$14.8 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 (H1 FY 2022: US$0.8 million). 
 
The decrease in cash balances is attributable to the repayment to Noteholders, 
through a debt tender offer during the Period, of US$144.6 million comprising 
the principal amount of US$126.4 million and PIK interest of US$18.2 million. 
The principal amount of Notes outstanding after the repayments to Noteholders 
is US$210,190,662. Cash costs of US$1.4 million attributable to the debt tender 
offer have been expensed in the Consolidated Income Statement under finance 
expense (refer to Note 6). 
 
Diamond debtors as at 31 December 2022 were US$4.9 million (H1 FY 2022: US$0.4 
million). 
 
Loans and Borrowings 
 
The Group had loans and borrowings (measured under IFRS) at Period end of 
US$241.7 million (H1 FY 2022: US$425.3 million) comprised of US$210.2 million 
of Second Lien Notes (including US$43.0 million of accrued interest and 
unamortised transaction costs of US$11.5 million) and bank loans and borrowings 
of US$nil (H1 FY 2022: US$78.6 million). Bank debt facilities undrawn and 
available to the Group as at 31 December 2022 were US$58.8 million (H1 FY 2022: 
US$0.6 million). Refer to note 8 for further details relating to the movement 
in loans and borrowings during the Period. 
 
Consolidated net debt as at 31 December 2022 was US$90.2 million (H1 FY2022: 
US$152.3 million).

Going concern considerations 
 
The Board has reviewed the Group's forecasts with various sensitivities 
applied, for the 18 months to June 2024, 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 recognise cash distributions payable to Petra upon forecasted receipt, 
or Petra's funding obligations towards Williamson upon payment. 
 
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) as at the date of this report: 
 
  * A 10% decrease in forecast rough diamond prices from January 2023 to June 
    2024 
  * A 10% strengthening in the forecast South African Rand (ZAR) exchange rate 
    against the US Dollar from January 2023 to June 2024 
  * A 5% increase in operating costs from January 2023 to June 2024 
  * A US$15 million reduction in revenue contribution from the effects of 
    product mix and/or Exceptional Stones 
 
  * 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 2024 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 when considered on a 
stand-alone basis. The combined sensitivity shows a covenant breach for the 
required ICR in the June 2024 measurement period. While the ICR is projected to 
be breached in this combined sensitivity, neither the Consolidated 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 cost savings and revenue 
enhancing opportunities through, for example, entering into partnership 
agreements on the sale of high-value or Exceptional stones. 
 
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 and Production 
 
Total Group capex for the Period increased to US$51.9 million (H1 FY 2022: 
US$16.7 million), comprising:

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     No Change - The third tender for FY 2023 saw 
diamond price                    term     a 2.2% increase in like-for-like prices 
                                          compared to the second tender, reversing the 
                                          trend of the previous two tenders.  An upward 
                                          movement of prices in the 2ct to 10ct size 
                                          ranges, as a likely result of the festive 
                                          season and easing of lockdown restrictions in 
                                          China, more than offset softer pricing in the 
                                          0.75ct to 2ct ranges.   While some volatility 
                                          is expected in pricing in the short-term 
                                          given the ongoing macroeconomic situation, we 
                                          remain encouraged by the supportive diamond 
                                          market resulting from the projected supply 
                                          deficit in the medium to longer term. 
 
2. Currency    High     Medium   Long     No change - The ZAR/USD rate weakened during 
                                 term     H1 FY 2023, opening at R16.44 and ending the 
                                          six-month period at R17.00 and this provided 
                                          some support for Petra.  The IMF's recent 
                                          positive sentiments on global growth (as 
                                          China eases its zero-COVID policies and 
                                          greater resilience is shown to impact higher 
                                          inflation/interest rates despite the ongoing 
                                          war in Ukraine) may drive the strength of 
                                          emerging market currencies, though this 
                                          remains to be seen for South Africa's Rand. 
 
3. Country     High     Medium   Long     No change - The risk of political instability 
and political                    term     remains in South Africa.  In addition, 
                                          rolling blackouts as a result of 
                                          load-shedding (electricity outages), continue 
                                          due to the inability of South Africa's 
                                          electricity provider to service the 
                                          population and businesses. 
                                          It has come to our attention that a portion 
                                          of the c.71kct parcel seized by the 
                                          Government of Tanzania ("GoT") in 2017 has 
                                          recently been sold. The proceeds of this 
                                          parcel are required to be allocated to WDL 
                                          under the Framework Agreement with the GoT. 
                                          We are engaging with the GoT to confirm the 
                                          application of the Blocked Parcel proceeds. 
 
4. COVID-19    Medium   Low      Short to No change - Despite the emergence of a new, 
pandemic                         medium   more transmissible sub-variant, COVID-19 
(operational                     term     levels at Petra's operations have remained 
impact)                                   low during H1 FY 2023.  The impact of COVID 
                                          19 infections continues to have no 
                                          significant effect on our operations or sales 
                                          processes at this time. 
 
Strategic 
Risks 
 
5. Group       Medium   Medium   Short to Higher - Whilst the Group's balance sheet was 
Liquidity                        long     strengthened through the repurchase of the 
                                 term     Company's loan notes totalling US$145m, 
                                          resulting in annual interest savings of c. 
                                          US$14 million, the Group has experienced 
                                          operational challenges, including lower 
                                          grades experienced at the Cullinan Mine which 
                                          are now expected to continue through FY 2024 
                                          and lower tonnes mined at Finsch in H1 FY 
                                          2023, which impact Petra's liquidity 
                                          position. 
                                          A number of ongoing mitigating actions are 
                                          being taken to address these challenges. 
                                          Halting operations at Koffiefontein and 
                                          placing the mine on care and maintenance will 
                                          have a positive impact on liquidity for the 
                                          Group. 
 
6. Licence to  Medium   High     Long     Higher - In light of operations at 
operate:                         term     Koffiefontein having ceased and consultations 
regulatory and                            taking place regarding placing the mine on 
social impact                             care and maintenance, increasing community 
& community                               tensions have led to disagreements on the 
relations                                 viability and delivery of certain projects 
                                          that are required to be implemented under 
                                          Social and Labour Plans. Management has 
                                          conducted extensive engagements between local 
                                          communities, the DMRE and the local 
                                          municipality to resolve these issues. 
                                          At Williamson, the IGM became operational at 
                                          the end of November 2022 with the 
                                          commencement of the pilot scheme. 
                                          Whilst no fatalities or serious injuries were 
                                          reported after the TSF breach at Williamson, 
                                          the livelihoods of a number of community 
                                          members were affected.  An assessment of the 
                                          impact on the surrounding communities and 
                                          potential remediation is currently nearing 
                                          completion. The TSF breach has resulted in 
                                          WDL providing immediate humanitarian relief 
                                          to those affected and work is underway to 
                                          develop an Entitlement Framework that will 
                                          enable community members who have been 
                                          impacted by the TSF breach to be 
                                          appropriately compensated.

Risks 
 
7. Mining;     Medium   High     Long     Higher - Lower grades at the Cullinan Mine 
 production                      term     are now expected to continue through FY 
(including ROM                            2024. This is attributable to the C-Cut cave 
grade and                                 maturity as the cave progresses from SW to 
product mix                               NE and the earlier than anticipated waste 
volatility)                               ingress from the overlying depleted mining 
                                          blocks.  Several mitigating actions are 
                                          underway to address these grade issues, 
                                          including: 
                                          .     Tailings treatment has been optimised 
                                          but is not in isolation sufficient to 
                                          address the grade reduction. 
                                          .     The re-opening of  Tunnels 36 (which 
                                          has already commenced) and 41 and the 
                                          establishment of Tunnels 46 and 50 (the 
                                          development of which have recently been 
                                          approved by the Board) will provide 
                                          additional volume from FY 2025 and more than 
                                          offset the impact of lower grades in FY 2023 
                                          /24. 
                                          .     Production from the CC1E project will 
                                          contribute meaningfully from FY 2025 and is 
                                          expected to see grades move back towards 
                                          40cpht. 
                                          Finsch's production target fell short of 
                                          guidance largely attributable to low machine 
                                          availability owing to an ageing underground 
                                          fleet, challenges with the centralised 
                                          blasting system and emulsion quality and an 
                                          extended rock-winder breakdown. 
                                          As noted above, production at Williamson has 
                                          been suspended for the remainder of FY 2023 
                                          due to the TSF breach and a restart is 
                                          reliant on the implementation of an interim 
                                          TSF, with operations anticipated to restart 
                                          in Q1 FY 2024. 
                                          Operations at Koffiefontein have ceased in 
                                          light of consultations to place the mine on 
                                          care and maintenance. 
                                          As a result of the above events, Group 
                                          production guidance has been lowered to c.

FOR THE SIX MONTH PERIODED 31 DECEMBER 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 six month period ended 31 
December 2022 comprise the Company and its subsidiaries, joint operations and 
associates (together referred to as the "Group"). 
 
2.     ACCOUNTING POLICIES 
 
The interim results, which are unaudited, have been prepared in accordance with 
the requirements of International Accounting Standard 34. This condensed 
interim report 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 2022, and any public 
announcements made by the Group during the interim reporting period. The annual 
financial report for the year ended 30 June 2022 was prepared in accordance 
with International Financial Reporting Standards adopted by the European Union 
("IFRS's") and the accounting policies applied in this condensed interim report 
are consistent with the polices applied in the annual financial report for the 
year ended 30 June 2022 unless otherwise noted. 
 
Basis of preparation including going concern 
 
Going concern 
 
The six-month period to 31 December 2022 delivered US$77.4 million in adjusted 
EBITDA and US$11.7 million in operational free cash flow for the Group, while 
Consolidated Net Debt reduced from $40.6 million as at 30 June 2022 to US$90.2 
million at 31 December 2022. 
 
Production 
 
The first half of FY23 saw all of the Petra operations deal with operational 
challenges. The Cullinan Mine experienced lower grades in the block cave on 
account of accelerated waste ingress, resulting in lower ROM carats being 
recovered, while also lowering the ROM carats production for the remainder of 
FY23 and FY24. Several mitigation steps are currently being investigated to 
minimise the impact of the lower grade. These include re-opening of T36 & T41, 
while also evaluating the addition of two more tunnels (T46&T50) adjacent to 
the current C-Cut centre. 
 
Finsch experienced production challenges as a result of machine availability 
owing to an aging underground fleet, challenges with the centralised blasting 
system and emulsion quality and an extended rock-winder breakdown. Several 
mitigation steps were implemented at Finsch, such as new underground equipment 
being delivered and commissioned, coupled with positive changes to the blasting 
process, the introduction of new long hole drill rigs and Load Haul Dump (LHDs) 
loaders as well as the appointment of individuals to a number of key positions. 
Furthermore, the 3-Level SLC project scope was amended to 90L, which adds 
additional production tonnes to the Life of Mine plan. The mitigation steps 
undertaken are expected to limit the lower production to FY23, with FY24 
expected to deliver as per previous guidance, while the new project is expected 
to add value beyond this Going Concern assessment period. 
 
Williamson performed well throughout FY2023 until the Tailings Storage Facility 
incident in the first week of November 2022. Production has been suspended 
until the new tailings storage facility is completed. It is assumed that 
production will only commence in July 2023. Progress is also being made in 
closing out the Framework Agreement with the Government of Tanzania and the MoU 
with Caspian). 
 
Following the unsuccessful sales process during the Period, production at 
Koffiefontein was stopped in November 2022 and the operation has subsequently 
been placed on care and maintenance. 
 
Diamond prices and diamonds market 
 
Diamond prices continued their upward trend, with a 12.7% increase on a 
like-for-like basis compared H1 FY22. While the Cullinan Mine did not 
contribute revenue from exceptional stones (>US$5.0 million), it has generated 
a robust $/ct price on account of a strong product mix, including several high 
value single stones that did not individually breach the US$5.0 million 
threshold. 
 
Diamond prices are now the highest since the peaks experienced in 2011/2012. In 
general, the market continues to be supported by a fundamental supply deficit, 
with robust demand recovery experienced post COVID-19. From a demand 
perspective, the Chinese lockdown had potentially 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 that it had entered into a framework agreement with the 
Government of Tanzania in December 2021, which sets out key principles on the 
economic benefit sharing amongst WDL shareholders, treatment of outstanding VAT 
balances, the allocation of proceeds of 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 will become 
effective upon completion of certain suspensive conditions. At the same time, 
Petra also announced entering into a non-binding Memorandum of Understanding 
(MoU) with Caspian Ltd to sell 50% (less 1 share) of Petra's indirect stake in 
WDL for a purchase consideration of US$15 million. 
 
Bond tender offer and South African banking facilities 
 
During the Period, the Group carried out a successful tender offer to its 
Noteholders, repaying the Noteholders US$144.6 million (principal plus 
interest), utilising existing cash reserves at the time, resulting in the 
deleveraging of the gross debt balances within the Group. 
 
The Group's ZAR 1 billion senior Revolving Credit Facility (RCF) facility 
remains undrawn at 31 December 2022, with the Group having access to the full 
ZAR 1 billion (US$58.8 million). 
 
The factors above, coupled with the further significant progress towards 
stabilising the Group's balance sheet 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 June 2024, 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 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 January 2023 to June 
    2024 
  * a 10% strengthening in the forecast South African Rand (ZAR) exchange rate 
    from January 2023 to June 2024 
  * a 5% increase in Operating Costs from July 2022 to Dec 2023 
  * a US$15 million reduction in revenue contribution from the effects of 
    product mix and/or from Exceptional Stones 
  *  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 June 2024 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 June 2024. 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 cost savings and revenue enhancing 
opportunities through entering into partnership agreements on the sale of 
Exceptional stones. 
 
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 an 
improving 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 review 
period. 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 2022 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 Mines 
 
The impairment tests for the Cullinan, Finsch and Williamson 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$615.3 million 
(pre-impairment). This follows US$21.1 million impairment reversal recognised 
at 30 June 2022 (comprising Koffiefontein impairment charge of US$0.3 million 
and a Group level impairment reversal relating to Williamson, previously 
recognised under IFRS 5, of US$21.4 million as Williamson was no longer 
considered an asset held for sale.) on a carrying value of the Group's 
property, plant and equipment of US$608.2 million (pre-impairment) at the time 
of recognition. 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 2022: 
US$12.5 million and 31 December 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 historical cost during FY2022. The recommencing of 
operations and the sales tenders at Williamson during the FY 2022 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 
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 GoT agrees to allocate proceeds from the sale 
of the Parcel to Williamson Diamonds Limited ("WDL"). Post period end, the 
Company was informed that a portion of the Parcel was sold and the Company is 
engaging with the GoT to confirm the application of the proceeds. For further 
details refer to note 18. 
 
While these engagements between the Company and the GoT are ongoing, 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, WDL will derive future economic benefit from the 
sale proceeds of the parcel (both the portion already sold and any portion that 
is yet to be sold). 
 
Recoverability of VAT in Tanzania 
 
The Group has VAT receivable of US$5.1 million (30 June 2022: US$2.6 million 
and 31 December 2021: US$1.8 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 31 December 2022, can be split into two identifiable 
component time periods as set out below: 
 
31 December 2022

                                     35.5       (6.0)      (26.9)           2.6 
 
Pre July 2017 and Post June 2020 
 
An amount of US$14.6 million (30 June 2022: US$8.6 million and 31 December 
2021: US$4.4 million) of VAT is receivable for the period for the period pre 
July 2017 and subsequent to 1 July 2020. The Group is considering various 
alternatives in pursuing payment in accordance with legislation. A provision of 
US$9.5 million (30 June 2022: US$6.0 million and 31 December 2021: US$2.6 
million), given the uncertainty around the timing of receipts of the amount 
outstanding, has been provided for against the US$14.6 million (30 June 2022: 
US$8.6 million and 31 December 2021: US$4.4 million) receivable resulting in a 
carrying value of US$5.1 million (30 June 2022: US$2.6 million and 31 December 
2021: US$1.8 million). 
 
While the remaining pre July 2017 and post 1 July 2020 VAT balance is 
considered recoverable, significant uncertainty exists regarding the timing of 
receipt. A discount rate of 14.00% inclusive of estimated country credit risk 
has been applied to the expected cash receipts. A 1% increase in the discount 
rate would increase the provision by US$0.3 million and a one year delay would 
increase the provision by US$0.6 million. 
 
During the Period, an impairment charge of US$3.5 million (30 June 2022: US$4.1 
million and 31 December 2021: US$0.7 million) 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, no expected credit 
loss reversal was recognised in the respective periods. For further detail 
refer to note 11. 
 
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. Refer to note 15 for further detail on the assumptions. 
 
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. 
 
Williamson Tailings Storage Facility 
 
On 7 November 2022, the tailings storage facility at the Williamson mine was 
breached, resulting in flooding away from the pit which has extended into 
certain areas outside of the mine lease area. As a result, remediation costs 
relating to the incident have been incurred during the Period and additional 
costs will be incurred going forward. The remediation costs comprise 
establishing the root cause of the failure, humanitarian relief to the affected 
community, livelihood and environmental restoration and costs to repair. 
Judgement has been applied by Management in assessing the future remediation 
costs. Management have considered the current work streams, the estimated time 
of completion and appropriate information received from suppliers and 
contractors involved in the remediation process. 
 
In H1 FY2023, US$4.4 million of costs, comprising management's best estimate 
based on the current information available, has been provided for in respect of 
ongoing remediation costs. 
 
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 2022 Annual Report and will be discussed in further detail in the FY 
2023 Annual Report: 
 
  * Provision for rehabilitation 
  * Inventory and inventory stockpile 
  * Depreciation 
  * Pension and post-retirement medical fund schemes 
  * Net investments in foreign operations 
  * Taxation 
 
3.     DIVIDS 
 
No dividends have been declared in respect of the current Period under review 
(30 June 2022: US$nil and 31 December 2021: US$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. 
 
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 ZAR16.27 (30 June 2022) to 
ZAR17.00 (31 December 2022) resulted in an unrealised gain of US$1.6 million 
(30 June 2022: US$36.5 million unrealised loss and 31 December 2021: US$28.7 
million unrealised loss) comprising an unrealised gain on foreign exchange 
contracts held at Period end of US$1.9 million (30 June 2022: US$0.7 million 
and 31 December 2021: US$0.1 million) and losses on inter-group foreign 
denominated loans of US$0.3 million (30 June 2022: US$37.2 million and 31 
December 2021: US$28.8 million); and a net realised foreign exchange loss of 
US$7.7 million (30 June 2022: US$12.6 million realised gain and 31 December 
2021: US$8.8 million realised gain) comprising US$20.4 million (30 June 2022: 
US$13.6 million and 31 December 2021: US$8.8 million) in respect of foreign 
exchange contracts closed during the Period and US$28.1 million in respect of 
realised foreign exchange losses on settlement of foreign loans, is included in 
the net finance and expense amount. 
 
2 The Notes redemption premium and acceleration of unamortised bank facility 
and Notes costs of US$8.2 million relate to the costs associated with the 
tender offer to Noteholders during the Period (30 June 2022: early settlement 
of RCF), comprising unamortised upfront costs of US$6.8 million (31 December 
2021: US$nil and 30 June 2022: US$1.6 million) previously capitalised and the 
make-whole premium of US$1.4 million. 
 
7.     PROPERTY, PLANT AND EQUIPMENT 
 
The net movement in property, plant and equipment for the Period is a decrease 
of US$13.0 million (30 June 2022: US$63.6 million decrease and 31 December 
2021: US$70.2 million decrease). This is primarily as a result of:

a) US$336.7 million Senior Secured Second Lien Notes 
 
A wholly owned subsidiary of the Company, 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 
 
On 27 September 2022, the Group repaid, through a debt tender offer to 
Noteholders, an amount of US$143,627,622, comprising the principal amount of 
US$125,590,338 and PIK interest of US$18,037,284. On 12 October 2022 a further 
US$1,000,667 was repaid to Noteholders comprising the principal amount of 
US$875,000 and PIK interest of US$125,667. The principal amount of Notes 
outstanding after the repayments to Noteholders is US$210,190,662. Cash costs 
of US$1,446,283 relating to the repayment of Noteholders have been expensed in 
the Consolidated Income Statement under finance expense (refer to Note 6). 
 
The Group performed an assessment under its accounting policies and the 
requirements of IFRS 9 as to whether the debt tender offer to the Noteholders 
represented a substantial modification. A qualitative test was performed which 
determined the terms of the Notes, repayment profile and interest rate were not 
amended or modified as part of the tender offer process therefore, no 
substantial modification was relevant. 
 
The remaining costs associated with issuing the Notes of US$13.9 million, after 
adjusting for the acceleration of US$6.8 million of unamortised costs 
associated with the debt tender offer to Noteholders which have been expensed 
through profit and loss within net finance expense (refer to note 6) have been 
capitalised against the principal amount and US$11.5 million remains 
unamortised as at 31 December 2022 (30 June 2022: US$18.5 million and 31 
December 2021: US$19.4 million). Interest of US$43.0 million has been accrued 
as at 31 December 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 
 
In 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") of ZAR1 billion (US$58.8 million) with 
Absa replaced the previous RCF and term lending arrangements with the previous 
South African lender syndicate comprising Absa, Nedbank, RMB and NinetyOne. 
 
The 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: 
  * 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) and 
  * certain covenant ratios as mentioned below. 
 
. 
 
The Group's debt and hedging facilities are detailed in the table below:

ZAR404.6 million (US$24.9 million) (capital plus interest) to settle the old 
RCF and ZAR893.2 million (US$54.9 million) (capital plus interest) to settle 
the previous Term Loan.

¹ The movement in the Kago Diamonds receivable of US$4.8 million (30 June 2022: 
US$6.9 million and 31 December 2021: US$6.4 million) is mainly attributable to 
repayments received from Kago Diamonds during the Period totalling US$3.6 
million (30 June 2022: US$nil and 31 December 2021: US$nil) and a foreign 
exchange decrease of US$1.2 million (30 June 2022: US$4.1 million decrease and 
31 December 2021: US$3.6 million decrease). 
 
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$1.3 million (30 June 2022: US$1.7 million and 31 December 2021: US$0.6 
million) and the balance of the KEM JV purchase consideration of US$nil (30 
June 2022: US$nil and 31 December 2021: US$nil). During H1 FY 2023 the Group 
received payments of US$0.3 million (FY 2022: US$2.5 million and FY H1 2022: 
US$1.2 million) from the KEM JV as settlement of the outstanding purchase 
consideration this did not result in any further expected credit loss reversal 
during the Period as the full reversal was accounted for in prior periods (FY 
2022: US$2.9 million and H1 FY2022: US$1.1 million). 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 2022: US$2.0 million and 31 December 2021: US$4.9 million). 
 
3 During the Period, Finsch declared and paid a dividend out of profits 
generated in FY2022 to its shareholders. The BEE partners received a gross 
dividend of US$9.8 million (30 June 2022: US$2.5 million). An amount of US$6.3 
million (30 June 2022: US$0.2 million) was used by BEE partners to repay a 
portion of their loans owing to the Group and a net cash payment of US$2.2 
million (30 June 2022: US$2.5 million) was received by the BEE partners, 
comprising Kago US$1.2 million (30 June 2022: US$1.3 million) and IPDET US$1.0 
million (30 June 2022: US$1.2 million).

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$40.2 
million (30 June 2022: US$42.0 million and 31 December 2021: US$48.6 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. Judgement 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 a previous Debt Restructuring in 
FY2021, Petra has assumed the BEE Lender facility obligations

BEE loans receivable refer to note 2.

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 Period, and the tailings facility failure 
at Williamson which have resulted 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. 
 
 During the Period 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 Period. 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 recognised a non-financial receivables 
charge of US$3.5 million, being management's estimate of the impact on the 
recoverability of the Tanzania VAT receivable.

31 December 2021 
 
During the 6 month period ending 31 December 2021, the Group reviewed the 
carrying value of its investments, loan receivables and operational assets for 
indicators of impairment. Following the assessment, no 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 
Period. 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 recognised a non-financial receivables impairment 
reversal of US$0.4 million, comprising US$0.7 million impairment charge being 
management's estimate of the recoverability of the Tanzania VAT receivable and 
an impairment reversal of US$1.1 million of the KEM JV receivable.

30 June 2022 
 
The operations of the Cullinan, Finsch, Koffiefontein and Williamson Mines are 
held at recoverable value as a result of FY 2021 impairments. During FY 2022, 
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 non-financial receivables charge of US$1.5 million 
comprising an impairment charge of US$4.1 million being 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.

Cullinan, Finsch, Koffiefontein and Williamson Mine 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 Cullinan Mine, Finsch, 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 31 December 2022 and 30 June 2022: 
 
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 2033 (FY 2022: FY 2031) 
                           Finsch: FY 2031 (FY 2022: FY 2030) 
                           Koffiefontein: FY 2025 (FY 2022: FY 2025) - current production 
                           has ceased and the operation has been placed on care and 
                           maintenance 
                           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 ten years; total 
and resources              resource processed 37.6 Mt (FY 2022: Current mine plan over the 
                           next nine years; total resource processed 36.4 Mt). Cullinan 
                           Mine is implementing a project for 2 additional tunnels (46 and 
                           50) resulting in an increase in reserves and mine plan. 
 
                           Finsch: Current mine plan over the next nine years; total 
                           resource processed 23.7 Mt (FY 2022: Current mine plan over the 
                           next nine years; total resource processed 23.2 Mt). Additional 
                           SLC project approved taking mining to 90L approved during H1 FY 
                           2023. 
 
                           Koffiefontein has been put on care and maintenance and has 
                           ceased production. 
 
                           Williamson: Current mine plan over the next eight years, total 
                           resource processed 38.0 Mt (FY2022:  Current mine plan over the 
                           next eight years, total resource processed 43.3 Mt). 
 
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 due to the mine plan aligning 
                           with the resource base estimated to be available at the end of 
                           the current mine plan. 
 
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 31 December 2022 impairment testing models starting price 
                           assumptions have been adjusted to reflect the improved pricing 
                           achieved during the FY2022. 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 
                           retained the contribution from Exceptional Stones at the 
                           Cullinan Mine at US$35.0 million per annum. 
 
                           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. 
 
Discount rate              A ZAR discount rate of 13.0% (30 June 2022: 13.0%) was used for 
                           the South African operations and a USD discount rate of 14.0% 
                           (30 June 2022: 14.00%) 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. 
 
Cost inflation rate        Long-term inflation rates of 3.5%-8.0% (30 June 2022: 
                           3.5%-7.5%) 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 ZAR17.00 (30 June 2022: ZAR16.04) for H2 FY2023 
                           reflecting the current volatility, inflationary pressures and 
                           quantitative tightening by Central banks, and ZAR16.75 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                 For impairment testing at Williamson, management used the above 
                           assumptions, noting that no sales were forecast for H2 FY2023 
                           following the TSF breach in November 2022. Accelerated 
                           depreciation of US$5.2 million attributable to the TSF assets 
                           has been included in the depreciation charge in mining and 
                           processing costs. During the FY2022, Williamson recommenced 
                           production.

16.            WILLIAMSON (30 June 2022) 
 
 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 Period, 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. For 
further information on the confiscated diamond parcel refer to note 18. 
 
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 is therefore not yet effective as at 31 
December 2022. Certain conditions precedent remain outstanding awaiting 
resolution from GoT. 
 
                  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 with Petra 
retaining a controlling interest in Williamson. 
 
Caspian's purchase will be funded through the settlement of US$15 million of 
past technical services payments owed by WDL to Caspian. 
 
The sale of the 50% less 1 share stake in the entity that holds Petra's shares 
in WDL is subject to the parties first entering into definitive transaction 
agreements and once such agreements are entered into, then 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. 
 
17.           CONTINGENCIES 
 
                 Williamson - Independent Grievance Mechanism ("IGM") 
 
The IGM is a non-judicial process that has the capacity to investigate and 
resolve complaints alleging severe human rights impacts in connection with 
security operations at the Williamson mine. It will be overseen by an 
Independent Panel of Tanzanian experts taking an approach informed by Tanzanian 
law, and with complainants having access to free and independent advice from 
local lawyers. The overall aim of the IGM is to promote reconciliation between 
the Williamson Diamond Mine, directly affected parties and the broader 
community by providing remedy to those individuals who have suffered severe 
human rights impacts. The Group has agreed to fund the remedies determined by 
the IGM. 
 
On 28 November 2022, the IGM became operational with the commencement of the 
IGM's pilot phase. The pilot phase, which is expected to continue until the end 
of March 2023, will allow for the IGM's systems and procedures to be further 
developed. Where appropriate, the design of the IGM will then be adjusted to 
take into account the learnings of the pilot phase. 
 
Whilst the IGM was still being established, a mechanism was set up to enable 
community members to confidentially and securely register alleged historical 
human rights grievances. This mechanism continued to receive grievances, with a 
significant amount of grievances having been registered to date. As the IGM is 
currently in its pilot phase, it is too early to evaluate the merits of these 
grievances. 
 
Judgement has been applied by management in assessing the merits and outcome of 
the grievances. Consideration was given, amongst other things, to the fact that 
the IGM remains in the pilot phase and is yet to assess the merits of the 
grievances registered. Accordingly, management is of the opinion that the 
estimated costs and outcome of the grievance remains uncertain and have 
therefore not raised a provision at Period end. 
 
18.           EVENTS AFTER THE REPORTING PERIOD 
 
                 Williamson Blocked Parcel 
 
Subsequent to Period end, it has come to the attention of the Company that a 
portion of the blocked diamond parcel of 71,654.45 carats that was confiscated 
by the Government of Tanzania ("GoT") in 2017 has recently been sold. Under the 
Framework Agreement entered into by the GoT, the Company and WDL in December 
2021, the GoT agreed to allocate the proceeds of this blocked diamond parcel to 
WDL. The Company is engaging with GoT to confirm the application of the 
proceeds.

INDEPENDENT REVIEW REPORT ON THE UNAUDITED FINANCIAL STATEMENTS OF PETRA 
DIAMONDS LIMITED 
 
Conclusion 
 
Based on our review, nothing has come to our attention that causes us to 
believe that the condensed set of financial statements in the half-yearly 
financial report for the six months ended 31 December 2022 is not prepared, in 
all material respects, in accordance with UK adopted International Accounting 
Standard 34 and the Disclosure Guidance and Transparency Rules of the United 
Kingdom's Financial Conduct Authority. 
 
We have been engaged by the company to review the condensed set of financial 
statements in the half-yearly financial report for the six months ended 31 
December 2022 which comprises Condensed Consolidated Income Statement, 
Condensed Consolidated Statement of Comprehensive Income, Condensed 
Consolidated Statement of Financial Position, Condensed Consolidated Statement 
of Cash Flows, Condensed Consolidated Statement of Changes in Equity and Notes 
to the Condensed Consolidated Interim Financial Statements. 
 
Basis for conclusion 
 
We conducted our review in accordance with International Standard on Review 
Engagements (UK) 2410, "Review of Interim Financial Information Performed by 
the Independent Auditor of the Entity" ("ISRE (UK) 2410"). A review of interim 
financial information consists of making enquiries, primarily of persons 
responsible for financial and accounting matters, and applying analytical and 
other review procedures. A review is substantially less in scope than an audit 
conducted in accordance with International Standards on Auditing (UK) and 
consequently does not enable us to obtain assurance that we would become aware 
of all significant matters that might be identified in an audit. Accordingly, 
we do not express an audit opinion. 
 
As disclosed in note 2, the annual financial statements of the group are 
prepared in accordance with UK adopted international accounting standards. The 
condensed set of financial statements included in this half-yearly financial 
report has been prepared in accordance with UK adopted International Accounting 
Standard 34, "Interim Financial Reporting. 
 
Conclusions relating to going concern 
 
Based on our review procedures, which are less extensive than those performed 
in an audit as described in the Basis for conclusion section of this report, 
nothing has come to our attention to suggest that the directors have 
inappropriately adopted the going concern basis of accounting or that the 
directors have identified material uncertainties relating to going concern that 
are not appropriately disclosed. 
 
This conclusion is based on the review procedures performed in accordance with 
ISRE (UK) 2410, however future events or conditions may cause the group to 
cease to continue as a going concern. 
 
Responsibilities of directors 
 
The directors are responsible for preparing the half-yearly financial report in 
accordance with the Disclosure Guidance and Transparency Rules of the United 
Kingdom's Financial Conduct Authority. 
 
In preparing the half-yearly financial report, the directors are responsible 
for assessing the company's ability to continue as a going concern, disclosing, 
as applicable, matters related to going concern and using the going concern 
basis of accounting unless the directors either intend to liquidate the company 
or to cease operations, or have no realistic alternative but to do so. 
 
Auditor's responsibilities for the review of the financial information 
 
In reviewing the half-yearly report, we are responsible for expressing to the 
Company a conclusion on the condensed set of financial statement in the 
half-yearly financial report. Our conclusion, including our Conclusions 
Relating to Going Concern, are based on procedures that are less extensive than 
audit procedures, as described in the Basis for Conclusion paragraph of this 
report. 
 
Use of our report 
 
Our report has been prepared in accordance with the terms of our engagement to 
assist the Company in meeting the requirements of the Disclosure Guidance and 
Transparency Rules of the United Kingdom's Financial Conduct Authority and for 
no other purpose.  No person is entitled to rely on this report unless such a 
person is a person entitled to rely upon this report by virtue of and for the 
purpose of our terms of engagement or has been expressly authorised to do so by 
our prior written consent.  Save as above, we do not accept responsibility for 
this report to any other person or for any other purpose and we hereby 
expressly disclaim any and all such liability.
