About Hochschild Mining plc:

Hochschild Mining plc is a leading precious metals company listed on the London Stock Exchange (HOCM.L / HOC LN) with a primary focus on the exploration, mining, processing and sale of silver and gold. Hochschild has almost fifty years' experience in the mining of precious metal epithermal vein deposits and currently operates four underground epithermal vein mines, three located in southern Peru, one in southern Argentina and one open pit mine in northern Mexico. Hochschild also has numerous long-term projects throughout the Americas.

CHAIRMAN'S STATEMENT

2011 Overview

Hochschild Mining has once again delivered a resilient performance in the wake of continuing global economic crisis. Thanks to the dedication and creativity of our whole team, we have been able to meet expectations on our key 2011 objectives, including the completion of feasibility studies for two of our Advanced Projects, the achievement of our annual operating targets and the ongoing evolution of our exploration based strategy. Importantly, we are also generating further opportunities to add to our already considerable growth plans as well as having the financial firepower to execute on attractive prospects.

A strong precious metals market again played its part in Hochschild's record financial performance in 2011, allowing us to significantly increase profits in the year whilst selectively mining lower ore grades in order to enable us to produce longer term stable future growth in uncertain markets. Despite significant increases in cyclical costs such as royalties, the Company recorded a considerable EBITDA increase of 42% to $563 million on the back of revenue of almost $1 billion. Earnings per share was up by 75% to 49 cents and the Board is therefore pleased to recommend a 20% increase in the total dividend for the year, to 6 cents per share, which confirms the confidence we have in the business going forward and the ongoing strength of our balance sheet.

Our management team has utilised 2011 to firmly embed the exploration strategy within the Company. During the year, Hochschild has completed over 315,000 metres of drilling with this number expected to increase by approximately 5% in 2012, reflecting the increased exploration budget of $90 million, representing another record for the Company. Our team has also appointed key new exploration managers as well as increased the number of geologists to ninety-two. This significant commitment has begun to bear fruit with the Company further optimising the life-of-mine of our core assets in 2011. In addition, we have swiftly brought two Advanced Projects through the pipeline to feasibility and continue to widen the number of drill targets and prospects, which in turn is considerably strengthening the Hochschild project pipeline. I firmly believe that this strategy will deliver profitable long term production growth to our shareholders.

Precious metals markets' volatility became a more prominent feature in 2011 than ever before with silver in particular displaying very large swings in price. The high of almost $50/oz was reached in May with investment demand becoming the main driver, but by December, silver prices had fallen by some 44% to below $30/oz again. With temperamental commodity markets reflecting broader global economic concerns, the mining sector in the UK was also very volatile. However, we believe that long term fundamentals for gold and silver remain strong and are confident that our business is well underpinned for the future.

Outlook

Over the next year, we expect to see the first crucial steps in the construction phase of our two exciting projects at Inmaculada and Crespo which have the potential to increase our silver equivalent production by 50 percent, or 10 million profitable ounces. The Board remains confident that Hochschild has the financial flexibility to continue pursuing high return investment opportunities whether in brownfield expansion at our existing mines, value enhancing acquisitions or adding to our exploration investment.

Corporate Responsibility

I am proud to report that Hochschild Mining has continued to make progress in the key area of Corporate Responsibility. During 2011, the Group's environmental management systems at all active operations were ISO14001 accredited. An enhanced Community Relations strategy was also formulated, underpinning our collective commitment to providing education as well as promoting health, nutrition and sustainable development in our local communities. A number of initiatives were launched during the year, most notably the 'Maestro Lider' (Leading Teacher) and 'Medico de Cabecera' (Mobile Doctor) programmes, further details of which will be provided in the Annual Report.

On the issue of safety, while a year-on-year reduction in the Group's accident frequency rate was achieved, it is with deepest regret that we report three fatalities during 2011. Operations were suspended immediately after each incident while investigations were carried out. We ensured that any resulting recommendations were immediately acted upon and that the affected families were supported. Our ongoing goal of zero fatalities remains our highest operational priority.

Board Composition

During the year, there were a number of changes to the Board. In light of Dionisio Romero's decision to retire as a Non-Executive Director at the AGM this May and Sir Malcolm Field retiring at the end of 2012, we moved swiftly to appoint Dr Graham Birch and Rupert Pennant-Rea to ensure the continued independent presence on the Board. Both of these Directors have brought with them extensive and relevant experience in the natural resource industry. I would also like to express my sincere gratitude to both Malcolm and Dionisio for their counsel and invaluable contributions to the Company since joining the Hochschild Board back in 2006.

On behalf of the Board, I would like to thank the entire talented Hochschild team for another year of strong performance, and our shareholders for your continued support.

Eduardo Hochschild

Executive Chairman

CHIEF EXECUTIVE OFFICER'S STATEMENT

I am pleased to announce another strong set of full year results with 2011 proving to be a record year for Hochschild, reflecting a solid operational performance and reinforcing our organic growth strategy and financial position. We firmly believe that the combination of our enviable operational, exploration and project development skills, combined with our premium geological land position spread across the Americas, is the key to maximising long term sustainable shareholder value.

Strategic progress

The first key pillar of our strategy encompasses our current assets and ensuring their long term sustainability. We have already increased the life of these assets extensively since our IPO in 2006, and in 2011 we continued this trend with significant increases at all three main operations. Resource life for the Company grew from 8.7 years in 2010 to 9.7 in 2011 with a 20% increase in resource life at Arcata, a 7% increase at Pallancata in Peru, and a 7% increase at the San Jose mine in Argentina where we continue to find new veins and extensions, thus increasing total resources at this exciting property to 172.2 million silver equivalent ounces.

2011 was also a key year in the development of our project pipeline, the second pillar of our strategy. One of its cornerstones is our aim to ensure the smooth progress of all our projects through their developmental stages. In this regard, the delivery of two feasibility studies on our Inmaculada and Crespo projects early in 2012 provided ample evidence of Hochschild's project management capability. These two exciting opportunities, based in our southern Peru cluster, give us an expected 50% uplift in our production base whilst generating an attractive return even at conservative price and resource assumptions.

Our most exciting asset is the 60% owned Inmaculada project. This is set to start construction with total initial capital expenditure of $315 million for a 3,500 tonne per day underground operation with total average annual production of 12 million silver equivalent ounces and a commissioning date in the fourth quarter of 2013. Total resources have now increased to almost 150 million silver equivalent ounces. We are confident that these resources will grow significantly from this excellent starting point in the same manner as our other mines and see Inmaculada develop into a major contributor for the Company.

In addition, Hochschild is pleased to see a positive result from its 100% owned Crespo project which is set to add another 2.7 million silver equivalent ounces from 2014 at an initial capital cost of $111 million for a 6,850 tonne per day operation. This open pit project is expected to have a low unit cost per tonne, high gold recovery rates and, given its proximity to Hochschild's other operations in southern Peru, will benefit from operational synergies. Current Inferred resources at Crespo are likely to deliver more mineable material for the project and the exploration team remains positive about the geological potential of the surrounding areas.

We remain excited by the potential of the Azuca deposit, especially with respect to the ongoing exploration of the newly discovered higher grade Colombiana and Cimoide Vivian veins. It is our intention to continue exploration work at the project throughout 2012 in order to consolidate resources and provide a more comprehensive picture of the complex vein structures present in the area before moving the project on to the feasibility study stage.

Exploration work continued in 2011, with a total of 315,373 metres of drilling completed. At our greenfield targets, we had positive results from our Company Makers pipeline at Victoria, Valeriano and Encrucijada in Chile, Mercurio in Mexico and Soranpampa in Peru, as well as strong progress at the Medium Scale Mosquito project in Argentina. Overall, Hochschild has again reaffirmed its exploration commitment with a $90 million budget for 2012, the largest in the Company's history, which will be invested in our brownfield, Advanced Projects and greenfield exploration programmes, which are expected to encompass drilling campaigns in 26 different locations across the Americas.

2011 overview

Our operations once again met their annual targets with production in 2011 of 22.6 million attributable silver equivalent ounces, comprised of 15.0 million ounces of silver and 127.3 thousand ounces of gold. San Jose continued to deliver, with silver equivalent production up 3% on the previous year - a highly creditable performance, with a particularly strong second half. At Arcata and Pallancata, we continued with our policy of adjusting the extracted grade to ensure a consistent and sustainable level of long term production as well as taking the opportunity afforded by high precious metal prices to process low grade material at both mines. The high prices have also allowed our Ares mine in southern Peru to continue operations throughout the year and into 2012, whilst our Moris mine in Mexico contributed just over 1 million silver equivalent ounces before its closure late in the fourth quarter.

In 2011 we continued experiencing cyclical cost inflation in line with the industry trend, primarily resulting from the ongoing high commodity prices. In Peru, unit costs were up by some 14% excluding royalties principally due to wage inflation in the industry and a higher proportion of production from narrower veins in the production mix at Pallancata and Arcata. In Argentina, Hochschild continued to face the challenges of ongoing high local inflation rates of some 25-30%, and although unit costs (excluding royalties) at San Jose only increased by 18%, this was principally due to a devaluation of the local currency of 6%, as well as the extraction of low cost superficial material located in new mine areas and also improvements in operational processes.

We expect overall 2012 unit cost inflation in Argentina to continue to be high, at around 25-30% for the same country specific reasons mentioned above, whilst in Peru we have forecasted an increase in unit costs of approximately 15% excluding royalties and the increased refining cost due to the effects of our dore project at Arcata. The main contributory factors to this increase are anticipated to be expected local industry inflation of 10% and the increasing number of stopes at our main operations.

The Group again achieved record results with revenue of just under $1 billion, up some 31% on 2010, driven by continuing strong precious metal prices, with the average silver price for 2011 up 53% and the average gold price up by 25%. EBITDA also rose sharply, by 42%, to $563 million (2010: $398million) with pre-exceptional EPS of $0.49 for the full year, approximately 75% higher than 2010.

We finished 2011 with a continuing strong cash balance of $627 million which together with our healthy operating cashflow, having increased 53% to $464.1 million in 2011, gives us the financial ability to embark on capital expenditure programmes for our Advanced Projects, pursue our ambitious exploration programme in 2012, continue investing in our main operations, and monitor any potential value accretive acquisitions to be assessed against our previously stated criteria. We also have minority investments worth approximately $350 million as at 31 December 2011, principally represented by our 25.2% stake in Gold Resource Corporation.

Outlook

Hochschild's production target for 2012 is 20.0 million attributable silver equivalent ounces, which takes into account the reduction of almost 300,000 silver equivalent ounces that will now not be recovered at Arcata as a result of the implementation of our dore project. The 2012 production target consists of similar levels of production at each of the core operations to those of 2011, with anticipated further declining production at Ares and Moris.

We have had a very busy start to 2012 with the completion of the Inmaculada and Crespo feasibility studies and we are excited that following the Board's approval of these projects and sanction of their capital expenditure requirements, the key stages of project construction can begin in earnest. Our strategy for this year will once again be to deliver on our production target, execute the first stages of the above mentioned project development and demonstrate consistent progress on our ambitious exploration programme, supported by its $90 million budget.

I am confident that Hochschild's talented and experienced team will continue to create opportunities for future value generation and that realising our 2012 targets will provide more evidence that we have the optimum strategy for long term growth.

OPERATING REVIEW

2011 Highlights

-- Full year production of 22.6 million attributable silver equivalent ounces, in line with target

-- Feasibility studies delivered on Inmaculada and Crespo projects; expected to add 10 million attributable silver equivalent ounces per year with production expected to commence at both projects at the end of 2013

   --   First stage of Arcata dore project completed 

CURRENT OPERATIONS

Production

Hochschild once again met its full year production target in 2011, producing 22.6 million attributable silver equivalent ounces, comprised of 15.0 million ounces of silver and 127,287 ounces of gold. In 2011, San Jose continued to deliver a strong performance. Lower production was reported at Pallancata and Arcata as the Company took advantage of high precious metals prices to process low grade material and also continued to adjust extracted grades to provide a sustainable level of long-term production and optimise the resource life of its main operations.

The Company has announced a production target of 20.0 million attributable silver equivalent ounces for 2012. Production at each of the Company's main operations is expected to be in line with 2011. As anticipated, production at the ageing Ares mine will continue to decline, reflecting lower tonnages and grades. Production at the Moris mine in Mexico is not expected to be material.

Costs

In 2011, the Company reported a 14% increase in unit cost per tonne excluding mine royalties at its main Peruvian operations (Arcata and Pallancata), to $60.8 per tonne (2010: $53.2). This increase was primarily due to a rise in labour costs reflecting higher precious metal prices, higher mining costs resulting from an increase in mined areas and a higher proportion of production from narrower veins.

In Argentina, unit cost per tonne excluding royalties increased by 18% to $169.6 per tonne (2010: $144.1) mainly as a result of local inflation impacting labour and materials costs and a higher consumption of plant reagents which in turn provided improved metallurgical recoveries (by approximately 5%). Local inflation was partially offset by local currency devaluation, lower mine development and the extraction of superficial low grade material (Saavedra). Please see page 22 of the Financial Review for further details on costs.

Production and sales

Arcata is located in the Department of Arequipa in southern Peru. It is a 100% owned underground operation that commenced production in 1964.

During 2011, the Company continued to adjust the extraction grades at Arcata towards the average reserve grade level in order to ensure a consistent and sustainable level of production. Full year silver equivalent production of 7.1 million ounces was 26% lower than 2010 (9.6 million ounces).

The Company took advantage of strong metal prices to process waste material from previous campaigns (see table below on Macarena Waste Dam Deposit). This material, whilst increasing overall annual treated tonnage by 7% to 687,966 tonnes (2010: 645,974 tonnes), was processed at a decreased average silver grade of 95g/t. In addition, in 2011 the Company mined in the lower grade border areas with associated narrower veins and increased dilution. This additional material was not part of Arcata's resource base.

In Q4 2011, the first stage of the project to convert 40% of Arcata's concentrate into dore was successfully completed. The second stage of the project will be completed in H2 2012 and subsequently 100% of Arcata's concentrate will be converted into dore. As a result of the metallurgical recoveries involved in the process, there will be an estimated reduction in production in 2012 of 291,000 silver equivalent ounces. Total investment for the project is approximately $14 million and the Company believes that this will be a highly profitable project as the resulting decrease in refining fees, commercial discounts and associated selling expenses will more than offset the treatment costs associated with the process.

Costs

Unit cost per tonne, excluding royalties, increased by 8% to $70.2 (2010: $65.0). Including royalties, the increase in 2011 was also 8% at $77.0 per tonne (2010: $71.1). Key drivers were a rise in the number of contractors employed in the mine due to the increased number of stopes, higher wage costs in line with industry inflation and higher diesel prices. These effects were partly offset by energy cost savings achieved following price renegotiations and by economies of scale resulting from the increase in treated tonnage.

In 2011, the silver/gold concentrate from Arcata was sold to Cormin, Korea Zinc Co. ltd and MRI Trading Ag.

10% of Arcata's production was processed into dore; all of which was sold to Johnson Matthey in 2011.

Resource life

The resource life of Arcata stands at 11.5 years as at 31 December 2011, up 20%, from 9.6 years in 2010, following an intensive drill campaign focused on the Baja, Marion, Blanca, Amparo, Lucrecia and Tunel 4 veins. In total, 94,656 metres of diamond drilling was completed during the year (2010: 76,506 metres) with significant intercepts including(6) :

([1]) The Company has a 60% interest in Pallancata

Production and sales

The Pallancata silver/gold property is located in the Department of Ayacucho in southern Peru, approximately 160 kilometres from the Arcata operation. Pallancata commenced production in 2007 and is a joint venture with International Minerals Corporation ("IMZ") in which Hochschild controls 60% and is the mine operator. Ore from Pallancata is transported 22 kilometres to the Selene plant for processing.

In 2011, full year production at Pallancata was 10.8 million silver equivalent ounces (2010: 12.3 million), a decrease of 12%. Although treated tonnage remained broadly flat compared to 2010, there was a fall in grades reflecting higher dilution from narrower veins, as well as the Company's decision to take advantage of the prevailing high precious metals price environment to process some lower grade economic material extracted from the borders of the main Pallancata vein. This additional material was not part of Pallancata's resource base.

Costs

Excluding mine royalties, unit cost per tonne increased by 18%, to $54.5 per tonne (2010: $46.2). Including royalties, the increase in 2011 was 17%, to $60.4 per tonne (2010: $51.8). This rise was principally due to increased wage costs resulting from industry inflation. In addition, the Company incurred higher mine service costs (transportation, energy and equipment hire) reflecting increased diesel prices and the development of new mine areas. A number of cost initiatives partially offset these factors, including a change to the mine backfill process leading to lower cement consumption, as well as cost efficiencies in explosives consumption.

In 2011, the silver/gold concentrate from Pallancata was sold to Teck Metals ltd., Aurubis and LS-Nikko Copper.

Resource life

The resource life of the Pallancata operation stands at 7.4 years as at 31 December 2011, up 7% compared to 2010 (6.9 years). During 2011, a total of 50,748 metres of diamond drilling was carried out over the course of the year (2010: 46,547 metres), mainly focused on the San Javier, Virgen del Carmen, Rina, Luisa, Pallancata West and Huararani veins with intercepts including(7) :

(*) The Company has a 51% interest in San Jose

Production and sales

The San Jose silver/gold mine is located in Argentina, in the province of Santa Cruz, 1,750 kilometres south-southwest of Buenos Aires. San Jose commenced production in 2007 and is a joint venture with McEwen Mining Inc (formerly Minera Andes Inc.). Hochschild controls 51% of the joint venture and is the mine operator.

San Jose delivered a robust performance in 2011, with silver equivalent production up 3% to 10.7 million ounces (2010: 10.4 million ounces). This was mainly a result of an anticipated increase in silver grades, as well as operational efficiencies that led to an increase in recovery rates to 89% for gold and 86% for silver (an increase of approximately 5% for both gold and silver compared to 2010). Silver grades rose by 12% year-on-year and silver production by 10% to 5.9 million ounces (2010: 5.3 million ounces). In line with the mine plan, the average gold head grade decreased by 5% and gold production by 4% to 80.95 thousand ounces (2010: 84.30 thousand ounces).

On 4 May 2011, following a 15 day production stoppage at the operation, the Group successfully concluded negotiations with the AOMA union (Argentine Mining Labour Association).

Costs

Unit cost per tonne, excluding royalties, increased by 18% to $169.6 (2010: $144.1). Including royalties, the increase in 2011 was 19%, at $181.7 per tonne (2010: $152.3). Local inflation in Argentina continues to run at between 25% and 30% and consequently the key driver of the rise in costs was wage cost inflation. A higher consumption of reagents also contributed to the increase in costs although this was offset by a significant improvement in recoveries. The high local inflation also impacted materials and supplies but was partly offset by a 6% devaluation of the Argentinian peso, lower mine development, the extraction of low cost, low grade, superficial material located in new mine areas (Saavedra) as well as efficiencies gained from improving operational processes (maintenance and other support processes). The Company expects cost increases in 2012 to be in the range of 25-30%, in line with the above mentioned local inflation.

In 2011, the dore produced at San Jose was sold to Argor Heraeus S.A. and Johnson Matthey Inc. The concentrate produced at the operation was sold to Teck Metals ltd., Aurubis and LS-Nikko Copper.

Resource life

Following an intensive drill campaign in 2011, the Company increased the resource life of the San Jose property by 7%, to 12.2 years (as at 31 December 2011). A significant portion of the San Jose property continues to be open at depth and laterally.

After a successful drilling campaign in the first half of 2011, the second half of the year was dedicated to completing geophysical and magnetometry workin order to identify new targets at the property. This work was successfully completed and provided areas of potential that were targeted in the Q4 drilling campaign and continuing into 2012. During the year, 55,678 metres of diamond drilling was conducted (2010: 53,692 metres), focused on the Luli, Susana, Orion and Pilar veins with significant intercepts including(8) :

Production and sales

The Ares mine, which commenced production in 1998, is a 100% owned operation located approximately 275 kilometres from the city of Arequipa in southern Peru. The Ares mine continued to operate for the full year, albeit at a lower level, producing 2.3 million silver equivalent ounces (2010: 2.7 million silver equivalent ounces).

Although production at Ares was expected to end in 2011, the Company continues to extract mineral from new veins and production will continue in 2012.Management also continues to monitor the grade and cost profile of the operation to ensure that it is in line with the Company's policy of producing profitable ounces. A new exploration programme for Ares is currently being developed for 2012, with the aim of identifying new resources.

100% of Ares' production is processed into dore, all of which was sold to Johnson Matthey in 2011.

Production and sales

The 100% owned Moris mine, is an open pit mine and is located in the district of Chihuahua, Mexico. Mine production ceased at Moris in September 2011, although continued leaching of the pads produced further ounces towards the end of the year. Full year production was 1.2 million silver equivalent ounces (2010: 1.4 million ounces).

Moris is currently in the final stage of the pads' cyanidation process although exploration continues in the area and the Company has been able to identify new exploration targets at Moris with the goal of identifying new resources.

In 2011, the gold/silver dore produced at Moris was sold to Johnson Matthey.

ADVANCED PROJECTS

The Company has three Advanced Projects: Inmaculada, Crespo and Azuca. The Company recently announced the results of feasibility studies, conducted by Ausenco, an independent consultant, on Inmaculada and Crespo. These projects are expected to contribute an average attributable annual production of 10 million silver equivalent ounces, increasing current production levels by 50%. Both projects are due to be commissioned in Q4 2013 and have an initial combined capital cost estimated at $426 million ($335 million attributable to Hochschild).

At Azuca, the Company has delayed the feasibility study to continue exploration work at the project throughout 2012 in order to consolidate resources and provide a more comprehensive picture of the complex vein structures in the area.

Inmaculada

Inmaculada is a 20,000 hectare gold-silver project located in the Company's existing operational cluster in southern Peru and is 60% owned and controlled by Hochschild, following the acquisition of a controlling stake in October 2010. The remaining 40% is held by the Company's joint venture partner at Pallancata, International Minerals Corporation ('IMZ').

The project is now set to start construction, with total initial capital expenditure of $315 million for a 3,500 tonne per day ('tpd') underground operation with average annual production of 12 million silver equivalent ounces (7 million attributable ounces), and is due to be commissioned in Q4 2013. The Company is also progressing with the exploration programme at the property which consists of 40 mining concessions with resources which are currently estimated at a total of 150 million silver equivalent ounces.

Changes from the 2010 scoping study resulting from the feasibility study process include: an update of the mineral resource; the use of only Measured & Indicated resources as the basis for the initial reserves; a change in the metallurgical process from flotation to leaching with the resulting change from a concentrate to dore as the final product; and an increase in the plant capacity from 3,000 tpd to 3,500 tpd. In addition, as a result of feasibility level geotechnical studies, the rock quality was determined to be poorer than anticipated which has affected dilution, mine capex and mining costs. All of these factors were incorporated in the new capex, cost and Net Present Value ('NPV') figures presented in the feasibility study results.

The feasibility study was conducted using only measured and indicated resources from the Angela vein. Summary results (on a 100% basis, applying a 1.5 g/t gold equivalent cut-off grade) are as follows:

-- Measured & Indicated resources: 7.07mt at an average grade of 4.07 g/t gold and 144 g/t silver containing approximately 925,100 ounces of gold and 32.8 million ounces of silver.

-- Inferred resources of 4.94mt at an average grade of 3.91 g/t gold and 152 g/t silver containing approximately 620,000 ounces of gold and 24.2 million ounces of silver.

-- Estimated mineral reserves (at a cut-off grade of 2.3 g/t gold equivalent): 7.80 mt at an average grade of 3.37g/t gold and 120 g/t silver containing approximately 845,000 ounces of gold and 30.1 million ounces of silver.

The project has been shown to be profitable even under conservative gold and silver price assumptions. The single, wide vein will also allow for lower mining costs and a metallurgical process with estimated recovery rates of 95.6% for gold and 90.6% for silver. The project's proximity to the Company's existing operations also offers logistical synergies and reduces execution risk. The principal execution risks facing the Inmaculada project are possible disruptions to the project schedule resulting from social or political instability and the project's dependence on third party supplies of electricity.

The feasibility study results confirmed that the project provides strong returns based on the existing reserve base. However, Hochschild is confident that the mineable resource base will be expanded by upgrading the inferred mineral resources in the South West and North East extensions of the Angela vein. Current project economics do not factor in almost five million tonnes of inferred resource containing over 60 million silver equivalent ounces which could almost double the life of mine. In addition, there is further geological potential at the Inmaculada property which hosts over 25 kilometres of gold/silver-bearing quartz veins of the low sulphidation type - veins which remain largely untested.

In 2011, exploration drilling at Inmaculada totalled 25,341 metres and in 2012, the drilling programme of 54,650 metres will focus on further exploration of the Angela vein and other known veins in the district.

Crespo

Crespo is 100% owned by Hochschild and is located in the Company's existing operating cluster in southern Peru. Crespo is also set to begin construction, with total initial capital expenditure of $111 million for a 6,850 tpd operation with an average annual production of 2.7 million silver equivalent ounces from 2014. This will be a relatively simple open pit project with high gold recovery rates, and again, will benefit from operational synergies due to its proximity to the Company's existing operations. The principal execution risks facing the Crespo project are possible disruptions to the project schedule resulting from social or political instability and the project's dependence on third party supplies of electricity.

Changes from the January 2011 scoping study resulting from the feasibility study process include: an update of the mineral resource; an increase in the plant capacity from 5,650 tpd to 6,850 tpd; and a change in the source of power, to a 25 km 60 KV transmission line connecting the Arcata operation to Crespo. Significant metallurgical testing was also carried out in order to review the overall process and optimise recoveries. These updates were all incorporated in the new capex, cost and NPV figures presented in the feasibility study results.

The updated resource estimate for Crespo replaced the previous estimate published in the scoping study and represented an increase in Measured and Indicated gold equivalent resources of 58% (304,000 ounces). Measured & Indicated resources now total 23.4 million tonnes at 0.45 g/t of gold and 39 g/t of silver containing 340,000 ounces of gold and 29.2 million ounces of silver.

Ore reserves, calculated by Ausenco, total 20.48 million tonnes at 0.46 g/t of gold and 39 g/t of silver with a cut-off grade of 0.33 g/t gold equivalent and metals prices of $1,300/ounce gold and $23/ounce silver.

The Crespo feasibility study results do not factor in almost 3.8 million tonnes of in-pit inferred resource, containing 6.6 million silver equivalent ounces with the potential to add almost 18% of mineable material at no further mining cost to the Company. There is also further geological upside at the Queshca gold target, to the north of the current feasibility study resource base. In addition, a drilling gap exists between Crespo and Queshca and encouraging geological evidence would suggest further potential for economic mineralisation.

The 2012 drill programme of 5,500 metres is focused on converting Inferred resources to the Indicated resource category and to increase the resource base and to continue exploring the Queshca target.

Azuca

The 100% owned Azuca project is also located in the Company's southern Peru operating cluster. In January 2012, the Company took the decision to delay the feasibility study at Azuca and continue exploration work at the project throughout 2012 in order to consolidate resources and to provide a more comprehensive picture of the dispersed vein structures present in the area.

Moreover, the Company believes that the geological potential of the Azuca property may produce richer structures that could further support the investment required to develop the asset but could alter the design and location of future mine and plant infrastructure, tailings ponds and other key equipment. The Hochschild Board has therefore approved an exploration programme for Azuca in 2012.

As of December 2011, the Azuca project has Measured & Indicated resources totalling 7.05 million tonnes at 0.77 g/t of gold and 188 g/t of silver containing 173,500 ounces of gold and 42.7 million ounces of silver.

Exploration at the site is ongoing, with promising higher grade intercepts suggesting the presence of new higher grade veins. The 2012 drilling programme will be focused on identifying further extensions of the Vivian-Yanamayo, Colombiana and Azuca West veins, with a drilling programme of 28,000 metres expected to be carried out in these new areas.

EXPLORATION REVIEW

2011 Highlights

-- $71 million invested in exploration in 2011; 33% brownfield,15% Advanced Projects and 36% greenfield(9)

   --   Resource life up 11% to 9.7 years 
   --   Total resources up 17% to 535 million silver equivalent ounces(10) 
   --   Increase in 'Company Maker' pipeline from 8 to 13 projects 

-- Record 2012 exploration budget of $90 million; 30% brownfield, 19% Advanced Projects, 35% greenfield, others and support 12% and technical support 4%.

-- 330,804 metres of drilling to be undertaken at 26 greenfield and brownfield projects across four countries

Hochschild's commitment to its exploration strategy has been reaffirmed with a 29% increase in the exploration budget for 2012 to $90 million, (from $70 million in 2010), the largest exploration budget ever for the Company. In 2011, investment in exploration totalled $71 million and 315,373 metres of drilling was completed at the Company's brownfield, Advanced Projects, greenfield and copper projects. The 2012 budget, representing 330,804 metres, will be split between exploration work at the Company's existing operations, the Advanced Projects and greenfield opportunities in Peru, Argentina, Mexico and Chile.

In 2011, the exploration programme delivered positive results, especially in respect to its key aims of increasing the resource life of the Company's core operations and expanding its project pipeline which now includes 13 'Company Makers' and 13 'Medium Scale' projects.

In 2012, exploration work at the Company's core operations will be mainly focused on improving resource quality. The main objective of exploration work at the Advanced Projects will be to incorporate additional resources at Inmaculada and Crespo, and at Azuca, to concentrate on the exploration of high quality resources that better support a significant investment. Exploration at the Company Maker projects will include continued drilling and further analysis. At the Company's Medium Scale projects, work will continue to develop those high-quality, early stage projects that have the potential to move through the pipeline to production. Work will also continue at the Company's copper projects and on the Company's generative programme to conduct further exploration on the Company's extensive land package of premium properties in four key countries. In 2011, the number of geologists employed by the Company was 92.

Brownfield exploration

In 2011, approximately 33% of the exploration budget was invested in brownfield drilling in the areas immediately surrounding Hochschild's three main operations. As a result, there was an 11% increase in resource life to 9.7 years (2010: 8.7 years).

The Company takes a very conservative approach to resource delineation and applies the same cut-off grades to reserves and resources. As a result, the Company has a high rate of conversion from resources to reserves.

For full reserve and resource tables, please see page 57.

Greenfield exploration

Approximately 36% of the 2011 exploration budget in 2011 was invested in the Company's greenfield programme, and in 2012, the proportion will be 35%. In 2011, a total of 41,546 metres were drilled as part of the greenfield exploration programme and in 2012, this is expected to increase to 47,500 metres.

Company Makers

The Company currently has 13 potential "Company Makers" which are projects with the potential to achieve 20-30 million silver equivalent ounces per year. These are typically high sulphidation, disseminated or gold/copper porphyry deposits and are generally open pit operations. In 2011, $12.4 million was invested in finding and developing such deposits and the 2012 budget has increased to $15.8 million.

Victoria

The Victoria project in northern Chile is 60% owned by Hochschild, with the remaining 40% held by Iron Creek Capital. Exploration work is delivering positive results at the property which covers 46,100 hectares of continuous strike length at the highly productive Domeyko Fault Zone. In 2011, 7,359 metres of drilling was completed. Exploration focused on the porphyry potential of the property and work was completed on a number of targets. The Picaron target was drill tested and significant alteration and anomalous copper mineralisation was encountered, proving it to be a true copper porphyry system. The resource is open and may increase in grade and thickness downstream. Selected intercepts from these exploration programmes include(11) :

--------------  ---------------------------------------------------- 
 

The drilling campaign of 6,800 metres in 2012 will include offset drilling of the recently reported intercepts in and around the Picaron target as well as continued definition drilling of the exotic copper oxide deposit. A data compilation and surface exploration programme will also be carried out over the entire Victoria property in 2012 and the drilling of defined targets will subsequently take place in the second half of the year.

Valeriano

The 100% owned Valeriano property in Chile is located 27 kilometres north of Barrick Gold Corporation's Pascua Lama project, in close proximity to the border with Argentina, and covers an area of 3,750 hectares. The property hosts both high-sulphidation as well as porphyry style disseminated gold mineralisation. The property has been explored by a number of mining companies in the past, including Phelps Dodge (1989-1991) and Barrick (1995-1997), both of which completed drill campaigns totalling 12,575 metres. No significant exploration had been undertaken at the property since 1997.

Hochschild commenced drilling at Valeriano in October 2011 and at the end of the year, 2,302 metres had been drilled, with anomalous gold and molybdenum intercepts reported. Further detailed geological work has identified targets in and adjacent to the primary tested target. Positive intercepts reported included:

In 2012 the Company plans to drill an additional 8,000 metres at Mercurio, around recently reported intercepts and will continue exploration activities, including drilling on adjacent targets.

Apacheta

At the 100% owned Apacheta project in Peru, 3,044 metres of drilling was completed in 2011 and the project moved up the project pipeline from prospect to drill target. The initial drilling programme tested high sulphidation and porphyry targets identified in the 2010 exploration programme. Drilling intercepted strongly altered rock with anomalous trace element geochemistry. In 2012 the 7,700 metre drilling campaign will complete the initial exploration programme at the Apacheta 1 and 2 targets and further targets will be defined

by a surface sampling programme.

Soranpampa

At the 100% owned Soranpampa project in Peru, 2,896 metres of drilling was carried out in 2011. The first phase of exploration was completed, with anomalous gold and molybdenum intercepts reported. Further detailed geophysical work has identified targets in and adjacent to the primary target already tested. Positive intercepts included(13) :

This is a 9,800 hectare high sulphidation epithermal and porphyry copper-gold type target in northern Peru optioned from a private party. The Company is in the process of completing the relevant permits and approvals process for the project.

Huachoja

This is a 3,000 hectare, high sulphidation epithermal target in southern Peru optioned from Teck Peru SA. A surface mapping and sampling programme will be completed in the first half of 2012 in order to select targets for drilling. An initial 1,500 metres drill programme will then be carried out in the second half of the year to test identified targets.

La Falda

The La Falda property in northern Chile, is located close to the Company's other projects in the area and was acquired in December 2011 as an earn-in project. The target is a porphyry gold-copper system. The Company has completed the permits and approvals process and will look to assign the necessary exploration budget for the project in order to commence a drilling campaign.

Medium scale projects

The Company's project pipeline also contains various Medium Scale properties in the prospects and drill target categories. These projects each have the potential to contribute 5-10 million silver equivalent ounces of production per year and tend to be low sulphidation epithermal gold/silver type deposits with varying base metal content and are typically mined underground.

In 2011, $7.9 million was assigned to finding and developing Medium Scale projects, and in 2012 the Company plans to invest $7.0 million in this category. Positive results were reported at a number of the Company's Medium Scale projects in 2011 and a number of properties entered the pipeline. These include the Pomona project in Argentina, the San Antonio project in Chile, and the Huacullo and Cuello Cuello properties in Peru.

Mosquito

Two rounds of drilling were completed at the 100% owned Mosquito property in Argentina in 2011. A total of 8,495 metres was drilled, testing over twelve different vein targets. The majority of the drilling did not intercept any anomalous vein mineralisation. In 2012 the 2,000 metre drilling programme will include offset drilling in and around the most anomalous intercepts reported to date. These intercepts are along the extension of the Cerro Morro (Extorre) vein deposit and positive results in 2011 included (13) :

In 2012, the exploration programme and 4,000 metre drilling campaign at La Flora will include a detailed mapping and sampling programme around the anomalous surface samples and drill hole intercepts identified in 2011. An IP geophysical survey will also be completed and identified targets will be subsequently drilled.

Argenta

At the 100% owned Argenta project in Argentina, 853 metres were drilled in 2011 to test the known vein system which reports strongly anomalous gold and silver mineralisation at surface and in drill hole. Assay results are being analysed before a drilling programme is put in place for 2012.

Astana/Farallon

Astana is a 100% owned project located in the Company's southern Peru cluster, with high sulphidation of disseminated gold/silver mineralisation. Historical drilling at superficial levels reported anomalous results in gold and silver associated to pyrite with values of 200 to 390 g/t Ag eq.

Farallon is a 100% owned low sulphidation silver veins system, located 1.5 km to the east of Astana. Previous drilling at superficial levels reported anomalous results in gold, silver, lead and zinc.Work conducted in 2011 was focused on attaining the relevant government and community permits and approvals for both projects. The community permit has been received, and in 2012 the exploration programme will include a 1,106 metre drilling campaign. Exploration activity will be carried out at Farallon, as well as the testing of anomalies in the Astana area.

San Martin

In 2011, work at the San Martin project in Peru was focused on obtaining the relevant government and community permits and approvals. The community permit has been received, and in 2012 the 1,800 metre drilling campaign will focus on defining potential mineralisation following previous drilling campaigns that intercepted high quality mineralisation.

Other Medium Scale projects

Huacullo

At the Huacullo project in Peru, the Company is in the process of completing the relevant government and community permits and approvals process.

Revenue

Gross revenue

Gross revenue from continuing operations increased 30% to $1,043.7 million in 2011 (2010: $802.7 million) driven by higher metal prices during the year which offset lower Group production.

Silver

Gross revenue from silver increased 37% in 2011 to $755.8 million (2010: $549.7 million) as a result of higher prices. The total amount of silver ounces sold in 2011 decreased to 21,792 koz (2010: 24,283 koz) mainly due to lower year-on-year production.

Gold

Gross revenue from gold increased 14% in 2011 to $287.8 million (2010: $253.0 million) also as a result of higher prices. The total amount of gold ounces sold in 2011 decreased to 182.0 koz (2010: 199.9 koz) mainly due to lower year-on-year production.

Gross average realised sales prices

The following table provides figures for average realised prices and ounces sold for 2011 and 2010:

Costs

Total pre-exceptional cost of sales increased 17% to $404.3 million in 2011 (2010: $345.7 million) mainly as a result of the increase in the direct production cost of 16% to $261.2 million (2010: $225.2 million). The direct production cost increment occurred mainly in mine costs as a result of an increase in the number of stopes mined. Direct costs also increased due to inflation in labour, supplies and oil prices in Peru and Argentina. Depreciation cost was $103.7 million in 2011 (2010: $101.6 million), other items costs which principally includes workers' profit sharing, were $32.4 million in 2011 (2010: $22.6 million) and change in inventories was $6.9 million in 2011 (2010: $(3.7) million).

Unit cost per tonne

The Company reported an overall increase in unit cost per tonne at its main operations of 16% in 2011 to $95.32 (2010: $82.3). For further explanation on the increase in unit cost per tonne please refer to page 7 of the Operating Review.

Cash costs

Co-product silver/gold cash costs are total cash costs multiplied by the percentage of revenue from silver/gold, divided by the number of silver/gold ounces sold in the year. Silver and gold cash costs increased from $9.3 to $13.0 per ounce and from $535 to $613 per ounce, respectively. Silver and gold cash costs from main operations (Arcata, Pallancata and San Jose) increased from $8.7 to $12.0 per ounce and from $504 to $561 per ounce, respectively. The increase in silver cash costs resulted from higher production costs and grade declines at both main Peruvian operations due to the incorporation of lower grade material. In addition, cash costs also increased due to higher precious metal prices causing rises in workers profit sharing contributions, higher commercial discounts and increased export taxes at San Jose.

By-product silver/gold cash costs are total cash costs less revenue from gold/silver, divided by the number of silver/gold ounces sold in the year. By-product cash costs for the period were $4.9 per silver ounce (2010:$ 3.0 per silver ounce) and ($1,987) per gold ounce (2010: ($1,153) per gold ounce).

* Cash costs are calculated to include cost of sales, treatment charges, and selling expenses before exceptional items less depreciation included in cost of sales.

Cash costs are calculated based on pre-exceptional figures. Co-product cash cost per ounce is the cash cost allocated to the primary metal (allocation based on proportion of revenue), divided by the ounces sold of the primary metal. By-product cash cost per ounce is the total cash cost minus revenue and commercial discounts of the by-product divided by the ounces sold of the primary metal.

Administrative expenses

Administrative expenses before exceptional items decreased by 3% to $64.4 million (2010: $66.2 million) mainly due to a lower provision for the Long-term Incentive Plan and the elimination of the Voluntary Contribution to the Peruvian Government following a revision to the tax regime in Peru.

Exploration expenses

As a result of the Group's decision to focus on organic growth through exploration, exploration expenses, which primarily relate to greenfield exploration, increased by 14% to $47.3 million in 2011 (2010: $41.5 million). Further detail on the exploration programme can be found in the exploration section on page 15.

In addition, the Group capitalises part of its brownfield exploration, which mostly relates to costs incurred converting potential resource to the Inferred or Measured and Indicated category. In 2011, the Group capitalised $13.2 million relating to brownfield exploration compared to $12.0 million in 2010, bringing the total investment in exploration for 2011 to $60.6 million (2010: $53.5 million). In addition, $10.1 million was invested in the Company's Advanced Projects.

Furthermore, in 2011, in line with the Company's strategy to further develop its production assets, capital expenditure on Advanced Projects and current operations included an additional $14 million to convert Inferred resources into Measured and Indicated resources.

Selling expenses

Selling expenses increased to $39.0 million (2010: $26.9 million) mainly as a result of export duties at San Jose, driven by the increase in gold and silver prices (export duties in Argentina are levied at 10% of revenue for concentrate and 5% of revenue for dore).

Other income/expenses

Other income before exceptional items was $7.1 million (2010: $5.6 million), mainly reflecting a $3.3 million export tax credit in Argentina. Other expenses before exceptional items reached $15.8 million (2010: $11.0 million), the principal component being an increase in mine closure provisions of $8.2 million due to the revision of the mine closure plans in all units.

Profit from continuing operations

Profit from continuing operations before exceptional items, net finance costs and income tax increased to $424.0 million (2010: $266.6 million) as a result of the factors detailed above.

Adjusted EBITDA

Adjusted EBITDA increased by 42% over the period to $563.4 million (2010: $397.7 million) driven primarily by higher silver and gold prices.

Adjusted EBITDA is calculated as profit from continuing operations before net finance income/(cost), foreign exchange loss and income tax plus depreciation and exploration expenses other than personnel and other exploration related fixed expenses.

Impact of the Group's investments in joint ventures and associates

An associate is an entity in which Hochschild has significant influence but not control and is accounted for using the equity method.

Hochschild's pre exceptional share of the profit/(loss) after tax of associates totalled $11.7 million in 2011 (2010: ($4.6) million), a result of the gain in the value of the Group's holding of Gold Resource Corp's common shares.

Finance income

Finance income before exceptional items increased by 15% to $4.7 million (2010: $4.1 million) mainly due to the increase of interest received on time deposits.

Finance costs

Finance costs decreased by 28% to $21.3 million in 2011 (2010: $29.5 million). Interest costs decreased to $15.3 million in 2011 (2010: $17.3 million). In addition, finance costs in 2010 included a $7.6 million loss on Zero Cost Collar derivative contracts.

In January 2011 Hochschild repaid in full its syndicated bank loan facility. The Group has no outstanding positions on currency or commodity hedges.

Foreign exchange losses

The Group recognised a foreign exchange loss of $1.6 million (2010: $0.03 million gain) as a result of transactions in currencies other than the functional currency.

Income tax

The Group's pre-exceptional effective tax rate increased to 35.6% in 2011 (2010: 32.9%). This increase is mainly explained by three new taxes introduced in Peru in Q4 2011, the New Mining Royalty ('NMR'), the Special Mining Tax ('SMT') and the Special Mining Assessment ('SMA'); detailed information on these taxes (collectively referred to as the 'New Taxes') is provided below. In addition, in 2011 Hochschild recognised the impact of a withholding tax related to dividends declared from the operating companies to the UK parent company.

Overview of the New Taxes

The application of the New Taxes is dependent on the presence or otherwise of a tax stability agreement with the Peruvian Government. These taxes replace a royalty, (the "Former Royalty") and a Voluntary Contribution (the 'Voluntary Contribution'). The Voluntary Contribution was calculated using a formula which, in the case of Hochschild, is approximate to 1.25% of Net Income.

NMR

The NMR applies to operating assets without stability agreements. It differs from the Former Royalty by changing the basis of calculation from sales to operating income. The NMR is calculated by applying a progressive scale of rates that range from 1% to 12% depending on the level of operating margin. A minimum amount of NMR is payable equivalent to 1% of Revenue. The Former Royalty was accounted for in the Cost of Sales line but the NMR will be accounted for in the Income Tax line.

SMT

The SMT is a new tax, also payable by mining companies with respect to operating assets without stability agreements, and is calculated on the same basis as the NMR. The rate of the SMT ranges from 2% to 8.4% depending on the level of operating margin. Unlike the NMR however, there is no minimum tax payable. The SMT is accounted for in the Income Tax line.

SMA

The SMA is an assessment raised on mining companies with respect to operating assets with stability agreements, to calculate an amount payable to the State on a voluntary basis. The rate used to calculate the assessment ranges from 4% to 13.12% of operating income, depending on the level of operating margin. The SMA is calculated on operating income after the deduction of payments due under the Former Royalty, which continues to be payable.

Hochschild does not have a stability agreement in place for Ares or Pallancata, and is therefore required to pay the NMR and the SMT in respect of those assets. The same will also apply for mines operated by the Company in Peru in the future (for example Inmaculada and Crespo).

In the case of Arcata, having reported to the Government that it waived its tax stability agreement in June 2009, the Company is required to pay the SMT. However the Peruvian Government is yet to confirm the waiver of the stability agreement. Therefore, Arcata will continue to pay the Former Royalty (which is accounted for in the Cost of Sales line).

The NMR and SMT payments will be deductable for the calculation of workers' profit share and Income Tax.

Exceptional items

Exceptional items in 2011 totaled $3.4 million after tax (2010: ($57.8 million). This mainly comprises:

Operating cashflow increased 53% to $464.1 million from $304.2 million in 2010, mainly due to higher metal prices. Net cash from investing activities decreased to $(139.9) million in 2011 from $199.0 million in 2010, primarily due to the reduction in the Company's holding in Lake Shore Gold during 2010 and planned increases in capital expenditure commitments during 2011 including the costs associated with progressing the Advanced Projects through to feasibility. Finally, cash from financing activities decreased to $(221.9) million from $(55.0) million in 2010, primarily as a result of the prepayment of the syndicated loan ($114.3 million), and incremental dividend payments to Hochschild Mining plc shareholders ($13.5 million in 2011 compared to $20.3 million in 2010) and to IMZ, the Group's joint venture partner in Pallancata ($26.0 million in 2011 compared to $54.0 million in 2010). As a result, total cash generated decreased from $448.2 million in 2010 to $102.3 million in 2011 ($346 million difference).

The Group's working capital position decreased to $(67.8) million in 2011 from $(1.1) million in 2010 primarily due to a decline of $31.5 million that resulted in a net other financial liability position in 2011, driven by a change in the value of embedded derivatives. The decrease was also a result of a higher net income tax position in 2011 compared to 2010 reflecting higher commodity prices, and higher trade and other payables and provisions in 2011 compared to 2010, due to higher workers profit sharing and mine closure provisions.

*Includes pre-shipment loans which were previously reported under working capital.

The Group reported net cash of $476.3 million as at 31 December 2011 (2010: $207.8 million). This was primarily driven by the increase in cash and cash equivalents from operating activities (of $102.0 million) and the decrease in long term and short term borrowings. In January 2011, the Group paid down in full its syndicated loan facility of $114.3 million.

In October 2011, the Group's 51% owned Joint Venture entity in Argentina repaid the entire outstanding principal and accrued interest on its shareholder and project finance loans. Hochschild received net proceeds of approximately $96 million from this repayment, consisting of approximately $66 million from the repayment of the project finance loan and approximately $30 million from the shareholder loan. Hochschild's joint venture partner, McEwen Mining Inc (formerly named Minera Andes Inc), received net proceeds of approximately $29 million from this repayment.

The Company's Convertible Bond has a conversion price (before adjustment for the recommended dividend) of GBP3.94 and allows the Company to force conversion of the bonds at any time after 20 October 2012 if, on each of at least 20 dealing days out of 30 consecutive dealing days, the Company's share price exceeds 130% of the conversion price (currently GBP5.12).

(1) Includes additions in property, plant and equipment and evaluation and exploration assets (confirmation of resources) and excludes increases in the closure of mine assets.

(2) Additions of $90.6 million in respect of the acquisition of Inmaculada is not reflected in this table.

2011 capital expenditure of $217.9 million (2010: $156.5 million) includes operating capex of $141.4 million, capitalised exploration costs of $13.2 million in respect of the Group's operating mines, $61.3 million capitalised in respect of Advanced Projects (Inmaculada, Crespo and Azuca) and administrative capex of $2.0 million.

Capital expenditure at Pallancata rose by $12.4 million in 2011 due to higher mine development costs reflecting an increase in mined areas developed, and higher mine contractors' rates. The construction of a new tailings dam and higher equipment costs also contributed to the rise.

Capital expenditure at San Jose increased by $7.8 million in 2011, reflecting local inflation in mine development costs.

Dividends

The directors recommend a final dividend of $0.03 per ordinary share which, subject to shareholder approval at the 2012 AGM, will be paid on 29 May 2012 to those shareholders appearing on the register on 4 May 2012. If approved, this will result in a total dividend for the year of $0.06 per share. Dividends are declared in US dollars. Unless a shareholder elects to receive dividends in US dollars, they will be paid in pounds sterling with the US dollar dividend converted into pound sterling at exchange rates prevailing at the time of payment. Our dividend policy takes into account the profitability of the business and the underlying growth in earnings of the Company, as well as its capital requirements and cash flow.

1 Notes to the consolidated financial statements

For the year ended 31 December 2011

The financial information for the year ended 31 December 2011 and 2010 contained in this document does not constitute statutory accounts as defined in section 435 of the Companies Act 2006. The financial information for the years ended 31 December 2011 and 2010 have been extracted from the consolidated financial statements of Hochschild Mining plc for the year ended 31 December 2011 which have been approved by the directors on 19 March 2012 and will be delivered to the Registrar of Companies in due course. The auditor's report on those financial statements was unqualified and did not contain a statement under section 498 of the Companies Act 2006.

2 Significant accounting policies

The accounting policies adopted are consistent with those of the previous financial year except for the adoption of new and amended standards.

The Group has adopted the following new and amended IFRS and IFRIC interpretations during the year. Adoption of these revised standards and interpretations did not have any effect on the financial performance or position of the Group.

-- IAS 24 "Related Party Transactions (Amendment)", applicable for annual periods beginning on or after 1 January 2011.

The IASB has issued an amendment to IAS 24 that clarifies the definitions of a related party. The new definitions emphasise a symmetrical view of related party relationships as well as clarifying in which circumstances persons and key management personnel affect related party relationships of an entity. Secondly, the amendment introduces an exemption from the general related party disclosure requirements for transactions with a government and entities that are controlled, jointly controlled or significantly influenced by the same government as the reporting entity. The adoption of the amendment did not have any impact on the financial position or performance of the Group.

-- IAS 32 "Financial Instruments: Presentation - Classification of Rights Issues", applicable for annual periods beginning on or after 1 February 2010.

The amendment changed the definition of a financial liability in order to classify rights issues (and certain options or warrants) as equity instruments in cases where such rights are given pro rata to all of the existing owners of the same class of an entity's non-derivative equity instruments, or to acquire a fixed number of the entity's own equity instruments for a fixed amount in any currency. This amendment did not have any impact on the Group after initial application.

-- IFRIC 14 "Prepayments of a minimum funding requirement (Amendment)", applicable for annual periods beginning on or after 1 January 2011.

The amendment provides guidance on assessing the recoverable amount of a net pension asset. The amendment permits an entity to treat the prepayment of a minimum funding requirement as an asset. The amendment did not have any impact on the financial statements of the Group.

-- IFRIC 19 "Extinguishing Financial Liabilities with Equity Instruments", applicable for annual periods beginning on or after 1 July 2010.

The interpretation clarifies that equity instruments issued to a creditor to extinguish a financial liability qualify as consideration paid. The equity instruments issued are measured at their fair value. In case this cannot be reliably measured, they are measured at the fair value of the liability extinguished. Any gain or loss is recognised immediately in profit or loss. The adoption of this interpretation did not have any effect on the financial statements of the Group.

-- "Improvements to IFRSs (issued in May 2010)", applicable for annual periods beginning on or after 1 July 2010 or 1 January 2011.

The IASB issued Improvements to IFRSs, an omnibus of amendments to its IFRS standards including IFRS 3 Business Combinations, IFRS 7 Financial Instruments - Disclosures, IAS1 Presentation of Financial Statements and IAS 34 Interim Financial Statements.

3 Segment reporting

The Group's activities are principally related to mining operations which involve the exploration, production and sale of gold and silver. Products are subject to the same risks and returns and are sold through the same distribution channels. The Group undertakes a number of activities solely to support mining operations including power generation and services. Transfer prices between segments are set on an arm's-length basis in a manner similar to that used for third parties. Segment revenue, segment expense and segment results include transfers between segments. Those transfers are eliminated on consolidation.

For internal reporting purposes, management takes decisions and assesses the performance of the Group through consideration of the following reporting segments:

-- Operating unit - Ares, which generates revenue from the sale of gold and silver.

-- Operating unit - Arcata, which generates revenue from the sale of gold, silver and concentrate.

-- Operating unit - Pallancata, which generates revenue from the sale of concentrate.

-- Operating unit - San Jose, which generates revenue from the sale of gold, silver and concentrate.

-- Operating unit - Moris, which generates revenue from the sale of gold and silver.

-- Exploration, which explores and evaluates areas of interest in brownfield and greenfield sites with the aim of extending the life of mine of existing operations and to assess the feasibility of new mines. The exploration segment includes expenses reflected through profit and loss and capitalised as assets.

-- Other - for the year 2011 the amount disclosed includes the profit or loss generated by Empresa de Transmision Callalli S.A.C. (a power generation company), HMX, S.A. de C.V. (a service company in Mexico), and the Selene mine, that closed in 2009 which, a consequence, is not considered to be a reportable segment . For the year 2010 the amount disclosed includes the profit or loss generated by Empresa de Transmision Callalli S.A.C. (a power generation company), Servicios Corporativos Hochschild Mining Mexico S.A. de C.V. (a service company in Mexico), and the Selene mine.

The Group's administration, financing, other activities (including other income and expense), and income taxes are managed at a corporate level and are not allocated to operating segments.

Segment information is consistent with the accounting policies adopted by the Group. Management evaluates the financial information based on International Financial Reporting Standards (IFRS) as adopted for use in the European Union.

The Group measures the performance of its operating units by the segment profit or loss that comprises gross profit, selling expenses and exploration expenses.

Segment assets include the items that could be allocated directly to the segment.

4 Acquisitions and disposals

(a) Acquisition of assets

Minera Quellopata S.A.C.

On 12 October 2010, the Group signed a Framework Agreement with International Minerals Corporation " IMZ", through which the Group acquired an additional 30% interest in the Inmaculada project (totalling 60%) in exchange for: (i) the purchase of US$20,000,000 of common shares in IMZ by way of a private placement, (ii) a payment of US$15,000,000, (iii) a commitment to fund the first US$100,000,000 needed to plan, develop and construct a mining operation within the Inmaculada property, and (iv) the transfer of Minera del Suroeste S.A.C.'s ownership in Minas Pacapausa S.A.C. to Minera Suyamarca S.A.C. Minera Oro Vega which transferred to Minera Quellopata S.A.C. "Quellopata", together with the Puquiopata project. The Group is the operator of the new venture pursuant to a separate management agreement similar in form and substance to the Pallancata management agreement.

This transaction has been accounted for as an asset acquisition on the basis that Quellopata has no existing processes.

As a result of the acquisition, the Group obtained control over Quellopata and consolidated it as a subsidiary. The net assets received in the asset acquisition were US$91,782,000 and the IMZ interest generated by the transaction was US$36,940,000. At 31 December 2010, the Group recognised a contingent consideration of US$39,243,000 and an obligation to IMZ of US$15,594,000.

During 2011 the Group paid to IMZ its obligation of US$15,594,000.

Gold Resource Corporation

Between 26 January 2010 and 5 February 2010 the Group acquired 440,500 shares of its associate Gold Resource Corp. for US$4,351,000 in the open market. In addition, on 8 March 2010 the Group signed a subscription agreement with Gold Resource Corp. by which the Group acquired 600,000 shares for a total consideration of US$5,172,000.

In addition on 27 May 2010 the Group acquired 631,579 shares of Gold Resource Corp. for a total consideration of US$6,000,000. Following completion of this purchase the Group's ownership in its associate increased to 25.28% on a fully diluted basis as at 31 December 2010.

At 31 December 2011 the Group's ownership in Gold Resource Corp. is 25.2% on a fully diluted basis.

(b) Disposal of shares

Lake Shore Gold Corp.

On 14 October 2010 the Group entered into an agreement with RBC Dominion Securities Inc., BMO Nesbitt Burns Inc. and CIBC World Markets Inc. to dispose of 109,000,000 shares held in Lake Shore Gold (approximately 27.3%) pursuant to a bought deal transaction, at a price of CAD$3.60 per share. The sale was completed on 3 November 2010. After this transaction the Group holds approximately a 5.4% interest, no longer has Board representation and no longer exercises significant influence over Lake Shore Gold. On 2 December 2010 the Group entered into a Block Trade Letter Agreement ("the Agreement") with RBC Capital Markets to dispose of the Group's remaining 21,540,992 common shares in Lake Shore Gold (approximately 5.4% interest in Lake Shore Gold on a fully diluted basis) at a price of CAD$3.70 per share raising total net proceeds of CAD$79,701,670. Due to the size of the combined sales (the initial disposal of 27.3% of Lake Shore Gold in November 2010 and the subsequent disposal of the remaining 5.4%), the second transaction was subject to shareholder approval which was granted on 8 February 2011. The transaction closed on the same date and a gain of US$6,385,878 was recognised in 2011 in respect of the disposal.

1 Mine-site exploration is performed with the purpose of identifying potential minerals within an existing mine-site, with the goal of maintaining or extending the mine's life. Once an inferred resource has been identified, costs incurred converting it to indicated and measured resources are capitalised.

2 Prospects expenditure relates to detailed geological evaluations in order to determine zones which have mineralisation potential that is economically viable for exploration. Exploration expenses are generally incurred in the following areas: detail mapping, detail sampling, geophysics, identification of local targets and reconnaissance drilling.

3 Generative expenditure is very early stage exploration expenditure related to the basic evaluation of the region to identify prospects areas that have the geological conditions necessary to contain mineral deposits. Related activities include regional and field reconnaissance, satellite images, compilation of public information and identification of exploration targets.

The following table lists the liabilities (generally payables) outstanding at the year end, which relate to the exploration activities of Group companies engaged only in exploration. Liabilities related to exploration activities incurred by Group operating companies are not included since it is not possible to separate the liabilities related to the exploration activities of these companies from their operating liabilities.

1 The provision represents the discounted values of the estimated cost to decommission and rehabilitate the mines at the expected date of closure of each of the mines. The present value of the provision has been calculated using a real pre-tax annual discount rate, based on a US Treasury bond of an appropriate tenure as at 31 December 2011 and 2010 respectively, and the cash flows have been adjusted to reflect the risk attached to these cash flows. Uncertainties in the timing for using this provision include changes in the future that could impact the time of closing the mines, as new resources and reserves are discovered.

2 Corresponds to the legal and voluntary workers profit sharing of the Group. Legal workers profit sharing represents 8% of taxable income of Peruvian companies. Voluntary workers profit sharing is determined by the Group taking into account the market conditions of employment. The balance of the provision as at 31 December 2011 is: (i) Legal (US$21,584,000), (ii) Voluntary (US$8,247,000).

3 Corresponds to the provision related to the long term incentive plans granted to designated personnel of the Group. Includes the following benefits: (i) Long term incentive plan, granted April 2011, payable April 2014, (ii) Long term incentive plan, granted May 2010, payable May 2013, and (iii) Exploration incentive plan, granted January 2011, payable 50% March 2013 and 50% March 2014. Only employees who remain in the Group's employment until the vesting date will be entitled to a cash payment, subject to exceptions approved by the Remuneration Committee of the Board. The provision represents the discounted values of the estimated cost of the long-term employee benefit. In 2011 there is a provision of US$2,594,000 that is disclosed under administrative expenses (US$1,467,000), exploration expenses (US$146,000) and capitalised as evaluation and exploration expenses (US$981,000).

4 This contingent consideration provision relates to International Minerals Corporation's discounted share of Hochschild's commitment to fund the first $100,000,000 needed to plan, develop and construct a mining operations within the Inmaculada property.

5 During 2011 the Group made an external review of the provision for mine closure for all its mining units. Consequently, at 31 December 2011 an increase of US$10,856,000 was recognised.

This amount includes the remuneration paid to the Directors of the parent company of the Group of US$4,816,370 (2010: US$6,996,557), out of which US$199,660 (2010: US$239,975) relates to pension payments.

(c) Purchase of additional interest in Inmaculada project

During 2010, the Group acquired an additional interest in the Inmaculada project effectively diluting the interest of its joint-venture partners, International Minerals Corporation ("IMZ"). This acquisition qualified as a small related party transaction under the UKLA Listing Rules in light of IMZ's 40% interest in the Pallancata Joint-Venture (note 4(a)).

24 Mining royalties

Peru

In accordance with Peruvian legislation, owners of mining concessions must pay a mining royalty for the exploitation of metallic and non-metallic resources. Mining royalties have been calculated with rates ranging from 1% to 3% of the value of mineral concentrate or equivalent, based on quoted market prices.

In October 2011 changes came into effect for mining companies, with the following features:

a) Introduction of a Special Mining Tax ("SMT"), levied on mining companies at the stage of exploiting mineral resources. The new tax is calculated by applying a progressive scale of rates ranging from 2% to 8.4%, of the quarterly operating profit. This new tax is in addition to existing mining royalties.

b) Modification of the mining royalty calculation, which consists of applying a progressive scale of rates ranging from 1% to 12%, of the quarterly operating profit. The former calculation was based on the monthly sales value of mineral concentrates.

The SMT and modified mining royalty are accounted for as an income tax in accordance with IAS12.

c) For companies that have mining projects benefiting from tax stability regimes, mining royalties are calculated and recorded as they were previously, applying an additional new special charge on mining, that is calculated using progressive scale rates, ranging from 4% to 13.12% of quarterly operating profit. This was the case for the Arcata mine unit.

As at 31 December 2011, the amount payable as former mining royalty (for mining unit Arcata), the new mining royalty (for mining units Ares and Pallancata), and the SMT amounted to US$709,000 (2010: US$2,946,000), US$1,261,000 (2010: Nil), and US$1,394,000 (2010: Nil) respectively. The former mining royalty is recorded as "Trade and other payables", and the new mining royalty and SMT as "Income tax payable" in the statement of financial position. The amount recorded in the income statement was US$11,921,000 of former mining royalty, disclosed as cost of sales (2010: US$11,223,000), and US$2,536,000 of new mining royalty and US$3,002,000 of SMT, both disclosed as income tax (2010: Nil).

Argentina

In accordance with Argentinean legislation, Provinces (being the legal owners of the mineral resources) are entitled to request royalties from mine operators. For San Jose, the mining royalty is fixed at 1.85% of the pit-head value of the production where the final product is dore and 2.55% where the final product is mineral concentrate or precipitates. As at 31 December 2011, the amount payable as mining royalties amounted to US$496,000 (2010: US$591,000). The amount recorded in the income statement as cost of sales was US$6,029,000 (2010: US$3,868,000).

Reserves and resources

Ore reserves and mineral resources estimates

Hochschild Mining plc reports its mineral resources and reserves estimates in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2004 edition ("the JORC Code"). This establishes minimum standards, recommendations and guidelines for the public reporting of exploration results and mineral resources and reserves estimates. In doing so it emphasises the importance of principles of transparency, materiality and confidence. The information on ore reserves and mineral resources on pages -- to -- were prepared by or under the supervision of Competent Persons (as defined in the JORC Code). Competent Persons are required to have sufficient relevant experience and understanding of the style of mineralisation, types of deposits and mining methods in the area of activity for which they are qualified as a Competent Person under the JORC Code. The Competent Person must sign off their respective estimates of the original mineral resource and ore reserve statements for the various operations and consent to the inclusion of that information in this report, as well as the form and context in which it appears.

Hochschild Mining plc employs its own Competent Person who has audited all the estimates set out in this report. Hochschild Mining Group companies are subject to a comprehensive programme of audits which aim to provide assurance in respect of ore reserve and mineral resource estimates. These audits are conducted by Competent Persons provided by independent consultants. The frequency and depth of an audit depends on the risks and/or uncertainties associated with that particular ore reserve and mineral resource, the overall value thereof and the time that has lapsed since the previous independent third party audit.

The JORC Code requires the use of reasonable economic assumptions. These include long-term commodity price forecasts (which, in the Group's case, are prepared by ex-house specialists largely using estimates of future supply and demand and long-term economic outlooks).

Ore reserve estimates are dynamic and are influenced by changing economic conditions, technical issues, environmental regulations and any other relevant new information and therefore these can vary from year to year. Mineral resource estimates can also change and tend to be influenced mostly by new information pertaining to the understanding of the deposit and secondly the conversion to ore reserves.

The estimates of ore reserves and mineral resources are shown as at 31 December 2011, unless otherwise stated. Mineral resources that are reported include those mineral resources that have been modified to produce ore reserves. All tonnage and grade information has been rounded to reflect the relative uncertainty in the estimates; there may therefore be small differences. The prices used for the reserves calculation were: Au Price: US$1080 per ounce and Ag Price: US$18 per ounce.

Currency option and dividend mandate

Shareholders wishing to receive their dividend in US dollars should contact the Company's registrars to request a currency election form. This form should be completed and returned to the registrars by 9 May 2012.

The Company's registrars can also arrange for the dividend to be paid directly into a shareholder's UK bank account. To take advantage of this facility, a dividend mandate form, also available from the Company's registrars, should be completed and returned to the registrars by 9 May 2012. This arrangement is only available in respect of dividends paid in UK pounds sterling. Shareholders who have already completed one or both of these forms need take no further action.
