MMG RESULTS FOR THE SIX MONTHS ENDED 30 JUNE 2020

KEY POINTS

  • MMG continues to proactively respond to the COVID-19 pandemic, with no cases identified to date at an MMG operation and all sites operating continuously since the outbreak began.
  • Net loss after tax of US$182.7 million, including a loss of US$158.0 million attributable to equity holders of the Company. The loss was primarily attributable to factors associated with COVID-19, specifically lower commodity prices and lower sales volumes, in particular at Las Bambas.
  • EBITDA of US$383.6 million was 41% lower than the first half of 2019.
  • Total copper and zinc production of 168,938 and 113,071 tonnes respectively.
  • Improved C1 cost performance, reflecting an ongoing focus on operating efficiency and cost discipline. Lower C1 unit costs compared to the first half of 2019 were recorded at all sites, except Las Bambas which was impacted by lower production volumes, due largely to COVID-19.
  • MMG's net debt increased by US$69.6 million during the six months ended 30 June 2020. The higher net debt was primarily attributable to the adverse impacts of COVID-19 and community action, on sales volumes, commodity process and ultimately, operating cash flow.
  • Las Bambas produced 131,697 tonnes of copper in copper concentrate in the first half of 2020. EBITDA of US$333.2 million was 38% below the first half of 2019. This result was largely attributable to lower copper prices. Sales volumes for the period were also impacted by community roadblocks that took place in the first quarter and COVID-19 transport restrictions.
  • Kinsevere produced 36,505 tonnes of copper cathode in the first half, 26% higher than the first half of 2019. This reflected a shift to mining at the Central pit, and together with processing cost savings, delivered EBITDA of US$13.4 million. This result, which was 56% above the same period in 2019, was achieved despite lower commodity prices.
  • Dugald River recorded EBITDA of US$9.1 million during the first half of 2020, significantly below the result for the first half of 2019. The impact of increases in zinc and lead sales of 19% and 33% respectively, was offset by lower commodity prices.
  • Rosebery produced 33,894 tonnes of zinc in zinc concentrate during the first half of 2020. EBITDA of US$48.5 million represented a 24% decrease on the first half of 2019. This was largely due to lower zinc and lead prices and lower production volumes as ore grades decline in deeper areas of the mine.
  • The Board did not recommend the payment of a dividend for the period.
  • Despite challenges associated with the COVID-19 pandemic, MMG maintains is original guidance for copper cathode production at Kinsevere of between 68,000 and 75,000 tonnes, and zinc production at Dugald River and Rosebery of between 225,000 and 245,000 tonnes. Guidance for Las Bambas has been withdrawn.

CHAIRMAN'S LETTER

Dear Shareholders.

I would like to thank you for your long-term support of MMG. On behalf of the MMG Board, I am pleased to present the Company's 2020 interim results.

In the first half of 2020, the spread of the COVID-19 pandemic across the world has greatly impacted the global economy. Some regions have fallen into recession, and the price of metals and minerals has fluctuated and fallen, affecting the Company's business performance to some extent. Faced with the challenges of a complex external environment, MMG has taken various active measures to strengthen pandemic prevention and control and to manage its operations during this time. In the first half of the year, the total production of copper was 168,938 tonnes and the total production of zinc was 113,071 tonnes, and we achieved an EBITDA of US$383.6 million during the reporting period.

The Company continues to adhere to the core value of "safety first", and gives top priority to the safety and health of employees. In response to the COVID-19 outbreak, we actively implemented contingency plans and formulated strict pandemic prevention procedures in accordance with the requirements of the local governments in our operating regions. We conduct comprehensive medical pre-screening of personnel arriving at site in addition to multiple re-examinations during and before shifts. We implemented social distancing and have strengthened hygiene practices and prevention and control measures. To date, there have not been any confirmed cases of COVID-19 in the mines operated by MMG. In the future, we will continue to focus our efforts on the prevention and control of the pandemic and on maintaining safe production. We will make every effort to protect the health and safety of our employees.

Across our operations we have taken active and effective measures to ensure continuous production during the pandemic. However, the national emergency that began in Peru in March has seen a shortage of employees at the Las Bambas mine, resulting in a 29% year-on-year decrease in copper output. On the other hand, optimisation of mining operations at the Kinsevere mine has resulted in a 26% increase in the output of copper cathode; the Dugald River mine has increased its mining volume and recovery rate, and its zinc output has increased by 6% compared to the same period in 2019; the zinc output of the Rosebery mine has decreased by 14% year-on-year due to a decline in ore grades and restricted mining areas.

Throughout the year we have continued to promote internal reforms and have implemented specific programs focused on reducing costs, conserving cash, increasing labour productivity, reducing the size of the Head Office, and giving mines more resources and responsibilities. We are increasing our presence in China to further strengthen our relationships with major stakeholders, and to seek collaborative opportunities, and we have continuously improved the international management model that we have built over the past decade. While developing the business, we are focused on organic growth and on making full use of the resources at hand. We are committed to building a corporate culture and philosophy that continuously pursues excellence and value, and creates mutual trust and win-win relationships with communities and stakeholders, and we continue to improve the Company's social and environmental performance.

China Minmetals Corporation Limited (CMC), the Company's major shareholder, continues to provide strong and enduring support. CMC is China's largest metal and minerals group with mining as its core business. CMC is the most international and has the strongest technological research and development capabilities in China, with extensive influence around the world. In the first half of this year, under the adverse conditions of the pandemic and with a downturn in the industry, CMC, produced operating indicators in line with progress and expectations, and the operating income increased by 10% year-on-year against the trend. As the flagship platform for CMC to develop its metal and mineral resources business, MMG will continue to receive strong support from its major shareholder, continue to develop its high quality assets and improve its competitiveness.

Looking ahead to the second half of the year, we believe that the current difficult situation is temporary. As the largest consumer of metal and mineral products, China is gradually showing signs of economic recovery as the pandemic is brought under control. The long-term positive trend remains unchanged which is a key reason for the recent improvement in metal prices. Although the aftermath of the pandemic is still unfolding, resulting in major uncertainties in the market in the short term, we are confident of overcoming the adverse

CHAIRMAN'S LETTER

impacts of the pandemic. We intend to keep up with the pace of economic development in China and the world and seize opportunities for the rebound in the metal and mining industry, as we continue our efforts to prevent and control the pandemic and ensure safe, healthy and productive operations. We will work with shareholders, employees, partners and other stakeholders, to create a better future together.

I would like to thank all shareholders, communities and business partners for their long-term support and my sincere thank you to all employees for their hard work.

CHIEF EXECUTIVE OFFICER'S REPORT

Dear Shareholders

The first half of 2020 has been presented with significant challenges as we have worked tirelessly to manage the impact of the COVID-19 pandemic on our business. While global uncertainty has resulted in weaker commodity prices, our first priority was maintaining safe operations at each of our sites, and ensuring the health and safety of our people, communities and contractors. I am pleased to report that we have been able to sustain continuous production at each site.

SAFETY

At MMG, our guiding value is safety. During the first six months of 2020 we recorded a Company-wide TRIF of 1.82, which represents an increase of 4% on the 2019 half year result. We remain steadfast in our commitment to eliminating injuries from our workplaces, recognising that every injury has the potential to cause long term effects on those injured, as well as their families. Across the entire business we have placed significant effort and focus on safe task management to ensure that all tasks are properly planned, risks are identified, controls are implemented and that our people have the required training and skills to complete tasks safely. Essential to this is ensuring that our leaders continue to engage with their teams through measures such as regular safety conversations, pre-start meetings, training and shared learnings.

As the COVID-19 pandemic continued to spread across the globe in the first half of this year, each of our operating regions faced challenges, with the greatest impacts experienced at our sites in Peru and the Democratic Republic of Congo. We have worked tirelessly to follow local government directions and to prevent the spread of the virus at our sites. We have implemented a broad range of measures to keep our people and communities safe, including enhanced hygiene measures, social distancing, administration of multiple tests for arriving to site, isolation protocols and community support. Additionally, we have worked with families of our people to share safety and prevention measures. I am proud that, to date, we have not recorded any COVID-19 cases at any of our operations, and we are doing everything possible to ensure that we keep it that way.

OUR PERFORMANCE

In the first half of 2020, MMG's operations produced 168,938 tonnes of copper and 113,071 tonnes of zinc.

While it is pleasing that we were able to sustain production at all operations despite the challenges presented by COVID-19, copper production at Las Bambas was impacted by limited workforce availability, community-related disruptions in January and February and conveyor belt repairs in early 2020. Las Bambas produced 131,698 tonnes of copper in concentrate in the first half. The operation's revenue of US$751.2 million was 17% lower than during the same period in 2019. This was primarily driven by lower commodity prices and lower sales volumes.

At Kinsevere, copper cathode production was 26% higher than the corresponding period in 2019, at 36,505 tonnes. This result is attributable to the higher mill throughout and higher ore feed grades due to the transition of mining back to the Central pit. Revenue also increased by 12% to US$198.5 million due to higher production and sales volumes.

Dugald River produced 79,177 tonnes of zinc during the first half. However, revenue reduced by 26% to US$120.9 million, largely due to the impact of lower metal prices.

Production of all metals at Rosebery was impacted by lower mill throughput and lower feed grades as mining activity continued to advance at deeper levels. Zinc production at Rosebery was 33,894 tonnes, while revenue decreased by 16% to US$119.4 million primarily driven by lower commodity prices and sales volumes.

CHIEF EXECUTIVE OFFICER'S REPORT

The Company has maintained its focus on cost and operational efficiency throughout 2020. This has resulted in improved C1 unit cost performance across all sites during the first half of the year, other than at Las Bambas due to the impact of COVID-19 on production volumes.

In the first half, MMG delivered an EBITDA of US$383.6 million which represents a 41% reduction on the corresponding period in 2019. This result primarily reflects the impact of COVID-19, specifically lower commodity prices and sales volumes. The Company's net debt also increased by US$69.6 million due to the impacts of COVID-19 on operating cash flow.

Due to ongoing uncertainty related to the impacts of COVID-19 in Peru, we have withdrawn guidance for Las Bambas at this time. Guidance for the production of copper cathode at Kinsevere remains unchanged at 68,000 to 75,000 tonnes and zinc production at Dugald River and Rosebery is expected to be between 225,000 and 245,000 tonnes.

OUR FOCUS

While managing the impacts of COVID-19 has been our focus for the first half, the management team has also placed significant attention and effort on our longer-term strategy and the transformation of our business. We have implemented cost saving and cash preservation initiatives and have worked to improve the productivity at each of our operations. These initiatives are part of our commitment to building a culture of excellence and an unwavering commitment to achieve the maximum value from out assets.

As we look to the rest of the year, we will undoubtedly continue to contend with market volatility and uncertainty due to the global pandemic. However, I am encouraged by some of the positive signs in the recovery of consumption and investment, particularly in China. Global economic recovery and stimulus measures, as well as supply side constraints in copper production, will likely continue to support commodity prices in the near term.

Consistent with our value of Safety First, our first priority remains the safety, health and wellbeing of our people and we will continue to leave no stone unturned in protecting our people from the impact of COVID-

19. Across all sites we have developed a range of strategies to maintain production activities or to deliver an efficient ramp up to normal activity levels. I am confident in the strength and resilience of our team and the support of our major shareholder - this dedication and support will ensure that we can emerge as a strong organisation from this global crisis.

Finally, on behalf of the MMG management team, I thank our shareholders, communities, contractors and all of our people for their support.

The following discussion and analysis of the financial information and results should be read in conjunction with the financial information.

Revenue decreased by US$196.0 million (14%) to US$1,191.4 million compared to the first half of 2019, mainly due to lower realised commodity prices (US$230.6 million) partly offset by higher sales volumes (US$34.6 million).

Unfavourable commodity price variances of US$230.6 million were driven by lower realised prices for copper (US$150.2 million), zinc (US$101.4 million), lead (US$6.9 million) and molybdenum (US$3.6 million). This was partly offset by higher prices for gold (US$23.8 million) and silver (US$7.7 million).

Higher sales volumes resulted from higher sales of copper cathode at Kinsevere (US$47.8 million), due to higher production. Higher production and drawdown of existing stockpiles at Dugald River also resulted in higher zinc, lead and by-product sales revenue (US$34.9 million).

This was partly offset by the impact of lower payable metal content for Las Bambas sales (US$45.4 million). Rosebery sales volumes were also lower (US$2.7 million), largely due to lower mill throughput and zinc feed grades.

With respect to Las Bambas, the combined impact of community blockades in the first quarter of 2020 and the suspension of trucking over March and April due to the COVID-19 pandemic, had a marginal impact on Las Bambas sales compared to the prior year comparative period, which was also impacted by community blockades.

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

Operating expenses include expenses of operating sites, excluding depreciation and amortisation. Site expenses include mining and processing expenses, changes in inventories, royalty expenses, selling expenses and other operating expenses.

Total operating expenses increased by US$51.3 million (7%) in the first half of 2020, driven by a net unfavourable inventory movement of US$195.2 million. This was primarily attributable to Las Bambas, with an excess of sales over production resulting in a net drawdown of copper concentrate stocks at site which had built up in 2019. The impact of the stock movement was partly offset by lower production costs across all sites (US$140.3 million). Further detail is set out below in the mine analysis section.

Exploration expenses decreased by US$5.3 million (40%) to US$8.1 million in the first half of 2020, with expenditure focused on targets in and around existing operations.

Administrative expenses increased by US$2.1 million (18%) in the six months ended 30 June 2020 driven by redundancy and other expenses associated with transformation and restructuring initiatives (US$8.1 million). This was offset by lower people costs, consultant spend and travel expenses as a result of headcount reductions and cash preservation initiatives (US$6.0 million).

Other income/(expenses) had a US$8.1 million unfavourable impact on EBIT in the first half of 2020. This compares to a favourable impact of US$10.9 million in the prior corresponding period, which was primarily attributable to foreign exchange gains. The US$8.0 million unfavourable impact in the current period was largely attributable to foreign exchange losses (US$9.7 million), partly offset by insurance proceeds received (US$2.7 million).

Depreciation and amortisation expenses decreased by US$44.4 million (10%) to US$406.9 million in the first half of 2020. The decrease was primarily attributable to lower mining and milling volumes at Las Bambas (US$28.3 million). Depreciation expenses were also lower at Rosebery (US$9.9 million) and Dugald River (US$2.5 million).

Net finance costs decreased by US$46.0 million (17%) to US$220.4 million compared to the first half of 2019. The decrease was mainly due to lower London Inter-Bank Offered Rate (LIBOR) applicable to floating rate debt compared with the first half of 2019 (US$26.4 million), together with the impact of lower debt balances (US$17.7 million).

Income tax credit of US$61.0 million, represents a US$63.0 million movement from the US$2.0 million income tax expense in the prior year comparative period. This reflects the higher pre-tax loss generated during the six months to 30 June 2020. The effective tax rate for the period to 30 June 2020 was 25.0%, with a prima facie income tax rate from operations of 32.0% partly offset by the impacts of non-creditable withholding tax and non-deductible items.

  1. Other operating expenses include changes in inventories, corporate recharges and other costs of operations.

Revenue of US$751.2 million was 17% below the first half of 2019, due to lower realised commodity prices (US$105.7 million) and lower copper (US$32.3 million) and molybdenum (US$13.0 million) sales volumes.

Copper concentrate volumes sold in the first half of 2020 (396,407 tonnes) were higher than the prior year comparative period (383,036 tonnes), however metal volumes did decline. Community blockades in the first quarter of 2020 and the temporary suspension of trucking in the second half of March to late April due to the impacts of the COVID-19 pandemic also impacted sales, however on a comparative basis this impact was similar to the impact of the community blockades that occurred in the first of 2019. Despite logistics challenges faced over the first half of 2020, the balance of copper in concentrate held at site has reduced from approximately 50,000 tonnes at 31 December 2019, to 38,000 tonnes as at 30 June 2020. At current

rates, it is anticipated that drawdown of this stock will extend into 2021. Lower molybdenum sales volumes were largely a result of plant de-bottlenecking works which completed in June 2020.

Lower mining costs largely reflect a change in the application of the deferred stripping accounting policy for better alignment between the cost of waste removal activity and timing of the economic benefit of this activity. This change, which has no cash impact, was first adopted in the second half of 2019 and resulted in capitalisation of approximately US$83.0 million of mining costs over the first half of 2020, that would have otherwise been expensed. Of this, US$50.1 million represented additional mining costs due to increased waste material movement compared to the prior year comparative period. The remaining US$32.9 million represents amounts that would have been capitalised in the first half of 2019, had the change in accounting policy been adopted at that time.

Further production cost savings of US$32.5 million reflect the rescheduling of maintenance costs (US$26.7 million) through business improvement initiatives and operational disruptions, together with lower mining and milling volumes compared to the first half of 2019, largely due to the impacts of the COVID-19 pandemic.

Total operating expenses were unfavourable by US$43.8 million (12%). This was largely due to a net drawdown of finished goods that had built up in 2019 (US$165.2 million), together with increased transportation costs due to higher concentrate volumes being sold. This offset the favourable US$115.4 million impact of lower production costs.

C1 costs for the first half of 2020 were US$1.15/lb compared to US$1.12/lb in the first half of 2019. The higher C1 is due to lower copper production volumes, partly offset by lower production expenses and higher by-product credits.

On 13 April 2020, the Company withdrew its 2020 guidance for Las Bambas, in response to the inherent uncertainty associated with the impacts of the COVID-19 pandemic. Despite the challenges presented by this event, Las Bambas has continued to operate continuously, albeit with limited workforce availability which has impacted activity levels at site and compliance with the original mine plan for much of the first half of the year. This, together with community related disruptions during January and February, as well as the need for repairs to the overland ore conveyor, have impacted the steady supply of ore to the mill.

The situation regarding COVID-19 remains highly uncertain, and the Company continues to work on a range of mine planning scenarios to effectively manage the current situation and ensure an efficient ramp-up towards normal activity levels, as workforce availability improves during the second half. Once greater operational certainty has been restored, updated production and other Las Bambas related guidance will be provided. This will include an update on the medium-term production outlook, including impacts to the development timeline for the Chalcobamba pit, with 2020 still targeted for permitting.

  1. Other operating expenses include changes in inventories, corporate recharges and other costs of operations.

Kinsevere revenue increased 12% to US$198.5 million compared to the first half of 2019, due to higher production and sales volumes (US$47.8 million), partly offset by lower realised copper prices (US$25.9 million).

Copper cathode production of 36,505 tonnes was 26% higher compared to the prior corresponding period. This reflected higher mill throughput, due to sustained plant stability, and a 14.5% increase in ore feed grade (3.25%, compared to 2.83% in the first half of 2019), with the majority of mined ore coming from the main Central pit, after mining at the Mashi pit ceased in mid-2019.

Ore mined was 12% below the first half of 2019, due to an extended wet season affecting production in the first three months of the year, and a temporary suspension of mining as a result of the COVID-19 lockdown. This did not impact on processing levels, with ore processed increasing by 9.0%, as mill feed was supplemented by the reclamation of long-term stockpiles and third-party ore.

14

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

Total production expenses decreased by US$4.4 million (3.0%) compared to the first half of 2019. Ore processing costs decreased by US$14.6 million (26%) mainly due to better ore quality, with lower gangue acid consuming ore and reduced silica in ore feed from external parties resulting in lower consumption of reagents. Despite reduced mining and waste movement volumes, mining costs remained relatively consistent with prior year comparative period. This resulted from a decision to cease capitalisation of mining costs at Kinsevere from 2020 onwards, with US$12.1 million having been capitalised in the first half of 2019. This decision was taken due to the limited remaining oxide life at the mine.

Overall lower production costs were offset by higher other production expenses (US$10.8 million) as a result of expenses incurred to mitigate the risk of COVID-19 at site, increased obsolete stock write-downs and higher customs duty expenses.

Increased freight and royalties compared to the first half of 2019, reflect higher sales volumes. Other operating expenses increased by US$12.4 million, mainly due to unfavourable inventory movements as a result of higher reclamation from ore stockpiles.

C1 costs for the first half of 2020 were US$1.86/lb, compared to US$2.49/lb in the first half of 2019. The lower C1 is due to increased production, together with lower cash production expenses.

Noting the ongoing uncertainty associated with COVID-19, the Company, at this stage, maintains its existing 2020 guidance for Kinsevere, with copper cathode production expected to be between 68,000-75,000 tonnes and C1 costs within the range of US$1.80-US$1.95/lb.

  1. Other operating expenses include changes in inventories, corporate recharges and other costs of operations.

Revenue decreased by US$42.9 million (26%) to US$120.9 million, primarily due to lower metal prices ($77.8 million), offset by higher sales volumes across all commodities (US$34.9 million). Higher sales volumes in the first half of 2020 were driven by higher zinc production, as well as a draw-down of existing stockpiles, with 2019 production and sales volumes having also been adversely impacted by significant flooding events.

Despite higher mining and milling volumes, total production expenses were US$11.9 million lower compared to the first half of 2019. Lower processing costs (US$8.1 million), largely resulted from gas and electricity credits received, with reduced energy expenditure. Other production expenses were lower in the first half of 2020 (US$6.1 million), with the comparative period including additional transportation costs incurred as a result of flooding events in February 2019. Other expenses were higher by US$13.5 million, attributable to inventory movements due to higher sales volumes.

Dugald River's zinc C1 costs were US$0.76/lb in the first half of 2020 compared to US$0.81/lb in the first half of 2019, with lower production expenses and higher volumes being the main drivers of this improved result, partly offset by the impact of overall higher zinc treatment charges on a comparative basis, which impacted by approximately US$0.08/lb.

Noting the ongoing uncertainty associated with COVID-19, the Company, at this stage, maintains its existing 2020 guidance for Dugald River, with production of between 170,000 and 180,000 tonnes of zinc in zinc concentrate and C1 costs of US$0.70-US$0.75/lb.

Rosebery produced lower volumes across all metals during the first half of 2020, mainly driven by lower mill throughput and lower feed grades, as mining activity moves deeper.

Revenue decreased by US$23.4 million (16%) to US$119.4 million due to lower commodity prices (US$2.7 million) and lower sales volumes (US$20.7 million). Negative price and volume variances were primarily attributable to zinc and lead, with impacts partly offset by higher by-product revenue with higher prices and sales volumes for both gold and silver during the first half of 2020.

17

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

Total production expenses decreased by US$8.6 million (13%) compared to the first half of 2019. Lower mining costs (US$5.3 million) were attributable to delays associated with seismic events in late 2019. Lower processing costs (US$2.6 million) reflect lower mill throughput as a result of lower availability of surface ore stocks.

Rosebery's zinc C1 costs were US$0.10/lb in the first half of 2020 compared to US$0.30/lb in the first half of 2019, reflecting higher precious metal by-product credits and lower production expenses.

Noting the ongoing uncertainty associated with COVID-19, the Company, at this stage, maintains its existing 2020 guidance for Rosebery, with production of between 55,000 and 65,000 tonnes of zinc in zinc concentrate and C1 costs of US$0.20-US$0.30/lb.

(359.9)

Net operating cash inflows increased by US$76.6 million (26%) to US$366.6 million. The impact of lower EBITDA (US$263.1 million), which was largely attributable to lower commodity prices, was offset by favourable working capital movements (US$127.1 million) and lower tax payments of $193.1 million. Net tax refunds of US$39.7 million in the first half of 2020 compared favourably to net tax payments of US$153.8 million in the prior year comparative period. This was in large part due to a change in Peruvian legislation that alters the timing for payment of withholding tax obligations.

Net investing cash outflows increased by US$106.8 million (72%) to US$255.3 million. This was mainly due increased capital spend at Las Bambas, including additional deferred mining costs of US$86.8 million in the first half of 2020, compared to US$3.9 million in the prior year comparative period.

Net financing cash outflows decreased by US$243.5 million (49%) in the first half of 2020. Included for the period were net repayments of borrowings of US$76.9 million (2019: US$261.0 million), together with payment of interest and financing costs of US$153.7 million (2019: US$197.5 million). Lower net repayments over the six-months to 30 June 2020 were due to net drawdowns on working capital facilities (US$130.0 million) and proceeds received in relation to equipment financing arrangements for new mine fleet at Las Bambas (US$63.9 million), offset by a step-up in scheduled amortisation for Dugald River debt (US$9.4 million).

Las Bambas Joint Venture Group borrowings at 30 June 2020 were US$4,783.2 million (31 December 2019: US$4,852.1 million) and Las Bambas Joint Venture Group cash and cash equivalents at 30 June 2020 were US$48.1 million (31 December 2019: US$90.9 million). For the purpose of calculating the gearing ratio, Las Bambas Joint Venture Group's borrowings have not been reduced to reflect the MMG
    Group's 62.5% equity interest. This is consistent with the basis of preparation of MMG's financial statements.

Under the terms of relevant debt facilities held by the Group, the gearing ratio for covenant compliance purposes is calculated exclusive of US$2,261.3 million (31 December 2019: US$2,261.3 million) of Shareholder debt that was used to fund the MMG Group's equity contribution to the Las Bambas Joint Venture Group. For the purpose of the above, it has, however, been included as borrowings.

Available debt facilities

At 30 June 2020, the Group (excluding the Las Bambas Joint Venture Group) had available to it undrawn debt facilities of US$300.0 million (31 December 2019: US$220.0 million). This was represented by:

  1. US$100.0 million (2019: nil) that was undrawn and available under a US$300.0 million revolving credit facility provided by Top Create Resources Limited, for general corporate purposes. This facility, which matures in December 2020, was established in June 2020, to replace a US$300.0 million revolving credit facility provided by the Industrial and Commercial Bank of China Limited (ICBC), Melbourne Branch that was also due to mature in December of 2020; and
  2. US$200.0 million (2019: 100.0 million) that was undrawn and available under a US$200.0 million revolving credit facility provided by Top Create Resources Limited, for general corporate purposes. In May of 2020,

19

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

the limit of this facility was increased from US$100.0 million to US$200.0 million and the maturity date extended from April to October 2021.

At 30 June 2020, the Las Bambas Joint Venture Group had available to it undrawn debt facilities of US$210.0 million (31 December 2019: US$350.0 million). This was represented by:

  1. US$105.0 million (2019: US$175.0 million) that was undrawn and available under a US$175.0 million revolving credit facility provided by Bank of China Limited (BOC), Sydney Branch, for general corporate purposes; and
  2. US$105.0 million (2019: US$175.0 million) that was undrawn and available under a US$175.0 million revolving credit facility provided by ICBC, Luxembourg Branch, for general corporate purposes.

In addition, as at 30 June 2020, the Las Bambas Joint Venture Group had an agreement with CMC and CITIC, each as direct or indirect off-takers of Las Bambas production, for early payment on cargoes already shipped and invoiced as well as pre-payments for inventory held at both port and site. Early payment and prepayments are permitted up to an aggregate amount of US$200.0 million, allocated to each party in their respective off-take proportions.

The Group's available external debt facilities are subject to covenant compliance requirements. The Group was not in breach of covenant requirements in respect of the Group's borrowings at 30 June 2020. Certain financial covenants are measured with reference to the financial performance of the Group or its subsidiaries, and may be influenced by future operational performance and community related disruptions

DEVELOPMENT PROJECTS

Drilling, permitting and engineering works continue at the Las Bambas Chalcobamba project, however were delayed as a result of the COVID-19 pandemic. Alongside revised guidance for Las Bambas more generally, an updated development timeline for the Chalcobamba pit will be provided when there is greater clarity around the ongoing extent of COVID-19 impacts and curtailment of the virus. In the interim, permitting for Chalcobamba by the end of 2020 is still being targeted.

There were no other major development projects noted during the six months ended 30 June 2020.

CONTRACTS AND COMMITMENTS

During the six months ended 30 June 2020, 225 contracts were reviewed either through market engagements or in-contract renegotiations. The approximate annual operational or capital values addressed by these activities comes to US$748.0 million.

Las Bambas

New and revised agreements were finalised for requirements in support of optimising production and expansion options for Las Bambas including; contracts for the supply of blasting service and explosives, additional mobile equipment, components (and associated maintenance services), spares, and contracts for engineering, civil and earthmoving services for projects. Multiple IT contracts, site services contracts, contracts covering Tailings Storage Facility and other site infrastructure capital works, multiple contracts covering operations, studies and exploration drilling services, and multiple goods and services contracts were also finalised in support of the operations. Agreements also include engagements with various local communities. A major activity in the six-month period was to review all contracts, with renegotiations conducted to ensure a sustainable cost base for the business. In addition, significant activity was undertaken to ensure surety of supply for critical commodities during COVID-19 pandemic to support continued operations.

Positive results continue at Las Bambas from on-going hydrogeological, geotechnical and sterilisation drilling completed during the first half of 2020.

Drilling continued at the near-surface, skarn and porphyry copper mineralisation at the Chalcobamba Southwest Zone, which is located immediately to the southwest of the current Chalcobamba pit. Coherent, higher-grade copper skarn (>1% Cu) is located beneath a shallow, unmineralised diorite intrusion that strikes east-west and dips gently to the south. Significant drill intercepts in this area continue to demonstrate that the Chalcobamba Southwest Zone is likely continuous with the main Chalcobamba mineralisation and is expected to drive an expansion of the Chalcobamba pit design.

In the DRC, exploration activities continued to focus primarily on the development of satellite copper oxide deposits within a roughly 50km radius of the Kinsevere mine. This activity continues to confirm and define several compelling copper-cobalt targets at the Nambulwa, Mewpu and Sokorshe II projects.

Full drilling and exploration results, as well as the full Table 1 JORC 2012 Code disclosure, can be found in full in the First Quarter Production Report that was lodged with the Hong Kong Stock Exchange on 23 April 2020. It can also be downloaded from www.mmg.com.

MATERIAL ACQUISITIONS AND DISPOSALS

The Group made no material acquisition or disposal in the six months ended 30 June 2020.

EVENTS AFTER THE REPORTING DATE

Minera Las Bambas S.A. is in the final stage of finalising a US$800.0 million credit facility with China Development Bank (CDB), ICBC Macau, BOC Sydney, and The Export-Import Bank of China Limited. The facility will be available to be drawn over its three-year tenor, with repaid sums available for redraw. The facility has been fully credit approved by lenders and loan documentation has been agreed. It is expected that execution of the facility will take place prior to the end of August 2020, once lenders have completed internal formalities related to the signing process. The facility will be unsecured.

The Company is also in the final stage of finalising a US$85.0 million credit facility with CDB. This three-year facility will be available for drawing over the first two years of its term, with funds repayable at the election of

the borrower. Repaid funds are not able to be redrawn. The facility has been fully credit approved by CDB and loan documentation has been agreed. It is expected that execution of the facility will take place prior to the end of August 2020, once lenders have completed internal formalities related to the signing process. The facility will be unsecured.

During July and August 2020, MMG Management Pty Ltd and MMG Dugald River Pty Ltd, wholly owned, indirect subsidiaries of MMG Limited, entered into commodity price swaps as follows:

  1. approximately 110,000 dry metric tonnes of copper with respect to sales contracts for Kinsevere copper cathode and the Company's equity share of sales contracts for Las Bambas copper concentrate, at a net price of approximately US$2.91/lb. These volumes relate to sales with quotational period nominations between August 2020 and January 2021.
  2. approximately 54,000 dry metric tonnes of zinc with respect to sales contracts for Dugald River zinc concentrate, at a net price of approximately US$1.08/lb. These volumes relate to sales with quotational period nominations between September 2020 and March 2021.

Other than the matters outlined in this announcement, there have been no matters that have occurred subsequent to the reporting date, which have significantly affected, or may significantly affect, the Group's operations, results or state of affairs in future years.

FINANCIAL AND OTHER RISK MANAGEMENT

The Group's activities expose it to a variety of financial risks including commodity price risk, interest rate risk, foreign exchange risk, credit risk and liquidity risk. The Group's overall risk management program focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group's financial performance. The Group can use derivative financial instruments, such as foreign exchange contracts and commodity swaps, to manage certain exposures. The Group does not and is prohibited from entering into derivative contracts for speculative purposes.

Financial risk management is carried out by the Group Treasury function under proposals approved by the Board. Group Treasury identifies, evaluates and manages financial risks in close cooperation with the Group's operating units. The Board approves written principles for overall risk management, as well as policies covering specific areas such as those identified below.

(a) Commodity price risk

The prices of copper, zinc, lead, gold and silver are affected by numerous factors and events that are beyond the control of the Group. These metal prices change on a daily basis and can vary significantly up and down over time. The factors impacting metal prices include both broader macro-economic developments and micro-economic considerations relating more specifically to the particular metal concerned.

The following table details the sensitivity of the Group's financial assets balance to movements in commodity prices. Financial assets arising from revenue on provisionally priced sales are recognised at the estimated fair value of the total consideration of the receivable and subsequently remeasured at each reporting date. At the reporting date, if the commodity prices increased/(decreased) by 10% and all other variables were held constant, the Group's post-tax loss would have changed as set out below:

(b) Interest rate risk

The Group is exposed to interest rate risk primarily through interest bearing borrowings and investment of surplus cash holdings. Deposits and borrowings at variable rates expose the Group to cash flow interest rate risk. Deposits and borrowings at fixed rates expose the Group to fair value interest rate risk.

The Group regularly monitors its interest rate risk to ensure there are no undue exposures to significant interest rate movements. Any decision to hedge interest rate risk is assessed periodically in light of the Group's overall exposure, the prevailing interest rate market and any funding counterparty requirements. Regular reporting that summarises the Group's debt and interest rates is provided to the Executive Committee.

During the period ended 30 June 2020, Minera Las Bambas S.A. entered into a notional US$2,100.0 million, 5- year amortising interest rate swap with respect to the floating 6-month LIBOR base rate applicable under its existing project facility, converting the floating rate to a fixed base rate of 0.43%, excluding credit margins.

At 30 June 2020 and 31 December 2019, if the interest rate had increased/(decreased) by 100 basis points, taking into account the interest rate swap, with all other variables held constant, post-tax loss and other comprehensive income (OCI) would have changed as follows:

(c) Foreign exchange risk

The Group operates internationally and is exposed to foreign currency exchange risk. The Group's reporting currency and functional currency of the majority of subsidiaries within the Group is US dollars. The majority of revenue received by the Group is in US dollars. The Group's foreign currency exchange risk arises predominantly from the currency of the countries in which the Group's operations are located. Any decision

24

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

to hedge foreign currency risk is assessed periodically in light of the Group's exposure, the prevailing foreign currency market and any funding counterparty requirements.

(d) Credit risk

Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Group. The Group is exposed to counterparty credit risk through sales of metal products on normal terms of trade, through deposits of cash and settlement risk on foreign exchange transactions. While the most significant exposure to credit risk is through sales of metal products on normal terms of trade, the majority of sales for mining operations were made under contractual arrangements; whereby provisional payment is received promptly after delivery and the balance within 30 to 120 days from delivery. All of the Group's trade receivables at 30 June 2020 are aged within six months of the invoice date.

Investments in cash, short-term deposits and similar assets are with approved counterparty banks and the intermediate holding company of the Company. Counterparties are assessed prior to, during and after the conclusion of transactions to ensure exposure to credit risk is limited to acceptable levels. The limits are set to minimise the concentration of risks and, therefore, mitigate the potential for financial loss through counterparty failure.

(e) Liquidity risk

Liquidity risk is the risk that the Group will encounter difficulty in meeting obligations associated with financial liabilities.

Management utilises short- and long-term cash flow forecasts and other consolidated information to ensure that appropriate liquidity buffers are maintained to support the Group's activities.

(f) Sovereign risk

The Group conducts all of its operations outside of Hong Kong and, as such, it is exposed to various levels of political, economic and other risks and uncertainties. These risks and uncertainties vary from country to country. Material risks include, but are not limited to, regime or policy change, fluctuation in currency exchange rates, changes to licensing regimes and amendments to concessions, licences, permits and contracts, and changing political conditions and governmental regulations. Changes in any mining or investment policies or shifts in political attitudes in the jurisdictions in which the Group operates may adversely affect the Group's operations and profitability. The decline in growth and macroeconomic activity in many developing nations has resulted in governments seeking alternative means of increasing their income, including increases to corporate tax, value added tax (VAT) and royalty rates, coupled with increased audit and compliance activity. The DRC Government, during 2018, made changes to the 2002 Mining Code and Mining Regulations. These changes were enacted (2018 Mining Code) and will result in an increased tax burden on mining companies.

Some of the countries in which the Group operates carry higher levels of sovereign risk. Political and administrative changes and reforms in law, regulations or taxation may impact sovereign risk. Political and administrative systems can be slow or uncertain and may result in risks to the Group, including the ability to obtain tax refunds in a timely manner. The Group has processes in place to monitor any impact on the Group and implement responses to such changes.

CONTINGENT LIABILITIES

Bank guarantees

Certain bank guarantees have been provided in connection with the operations of certain subsidiaries of the Company primarily associated with the terms of mining leases, mining concessions, exploration licences or key contracting arrangements. At the end of the year, no material claims have been made under these

25

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

guarantees. The amount of these guarantees may vary from time to time depending on the requirements of the relevant regulatory authorities.

These guarantees amount to US$348.2 million as at 30 June 2020 (31 December 2019: US$373.4 million). The Group has an Australian dollar 200.0 million (approximately US$137.3 million), revolving bank guarantee facility with Bank of China Limited, Sydney ("BG Facility"), which is guaranteed by CMN. MMG has entered into a counter-indemnity agreement in favour of CMN capped at 27.39% of the maximum principal amount outstanding under the BG Facility.

Following the sale of Century mine in 2017, the Group has procured certain bank guarantees amounting to US$133.2 million (31 December 2019: US$135.7 million) for the benefit of New Century Resources Limited ("New Century") until 31 December 2026. New Century is legally required to punctually meet all obligations and must use best endeavours to ensure that no demand is made under the bank guarantees. New Century must ensure that, within 90 days of the end of each financial year, the bank guarantee is reduced by not less than 40% of New Century's EBITDA in respect of a financial year. At 30 June 2020, the Group has recognised financial liabilities of US$133.2 million (31 December 2019: US$135.7 million) in relation to the New Century bank guarantees, which are included in other financial liabilities in the condensed consolidated interim financial statements.

Contingent liabilities - tax-related contingencies

The Group has operations in multiple countries, each with its own taxation regime. The nature of the Group's activities triggers various taxation obligations including corporation tax, royalties, withholding taxes, transfer pricing arrangements with related parties, resource and production-based taxes, and employment-related taxes. Application of tax laws and interpretation of tax laws may require judgement to assess risk and estimate outcomes, particularly in relation to the application of income taxes and withholding tax to the Group' cross-border operations and transactions. The evaluation of tax risks considers both assessments received and potential sources of challenge from tax authorities. Additionally, the Group is currently subject to a range of audits and reviews by taxation authorities in Australia, Peru, Laos and the DRC. For some of the tax matters under audit in Peru, if unfavourable assessment resolutions were ultimately issued, MLB intends to appeal and not pay any assessed amount. No disclosure of an estimate of financial effect of the subject matter has been made in the interim financial statements as in the opinion of management, such disclosure may seriously prejudice the position of the Group in dealing with these matters.

Tax matters with uncertain outcomes arise in the normal course of business and occur due to changes in tax law, changes in interpretation of tax law, periodic challenges and disagreements with tax authorities, and legal proceedings. The status of proceedings for such uncertain tax matters will impact the ability to determine the potential exposure and, in some cases, it may not be possible to determine a range of possible outcomes or a reliable estimate of the potential exposure.

Included within such uncertain tax matters is an audit of the 2014 tax year for MLB in relation to withholding taxes on fees paid under certain loans, which were provided to MLB pursuant to facility agreements entered into among MLB and a consortium of Chinese banks in connection with the acquisition of the Las Bambas mine in 2014. MLB received an assessment notice ("Assessment") in July 2020 from the Peruvian tax authority (National Superintendence of Tax Administration of Peru or "SUNAT"), which advised that, in its opinion, MLB and the Chinese banks are related parties and thus a 30% withholding tax rate ought to be imposed rather than the 4.99% applied. The Assessment of omitted tax is PEN 60,687,851 (approximately US$17.3 million). The total Assessment of omitted tax plus penalties and interest imposed by SUNAT is PEN 154,193,808 (approximately US$44.0 million).

Having received external legal and tax advice, the Group has formed the view that the company and its controlled entities are not related parties to Chinese banks under Peruvian tax law. MLB notes that the Peruvian tax law was amended to apply from October 2017 onwards to provide expressly that parties are not related by being under state ownership for the purposes of withholding taxes. MLB intends to appeal the

26

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

Assessment and not to pay the assessed amount to SUNAT pending resolution of the appeal. SUNAT could potentially bring a similar challenge regarding the rate of withholding tax applied by MLB in the 2015 and 2016 tax years and the part of the 2017 tax year before the amendment to the Peruvian tax law. Where MLB is not successful in rebutting or appealing such challenge(s), this could result in significant additional tax liabilities.

The Group continues to proactively cooperate with the relevant taxation authorities and to actively manage these audits and reviews. Where appropriate, the Group has filed appeals with either the relevant tax authority or the tax court. For all such open tax matters the Group presently has, any ultimate obligation would depend on future resolution of the matter and currently, a payment is either not probably or cannot be measured reliably. As such, no provision has been reflected in the condensed consolidated interim financial statements for such tax matters.

Contingent liabilities - other contingencies

Mining Company Katanga SARL ("MCK") filed a claim against MMG Kinsevere SARL ("MMG Kinsevere"), a subsidiary of the Group, to compensate MCK for losses suffered as a result of Kinsevere's decision to not renew or extend the mining services contract with its associate entity MCK Trucks (then known as NB Mining SA) in 2018 on the basis that MCK was entitled to a "life of mine" agreement with Kinsevere.

MCK is seeking an award of losses suffered and punitive damages. MMG Kinsevere and the Company regard the claim as unfounded and opportunistic, and the amount claimed as completely disproportionate to the losses that could reasonably have been suffered. The Group is vigorously contesting the claim. Court proceedings between MMG Kinsevere and MCK in the DRC have not progressed due to court closures in the DRC as a result of the COVID-19 outbreak. MCK obtained freezing orders in February 2020 over certain assets of Kinsevere, which have been partly enforced over US$15.0 million cash held in bank accounts in the DRC.

Considering the uncertainty around this matter and the fact that there is no present obligation for Kinsevere to make any payments, nor such payment being reliably estimated at this time, no provision has been recognised for this matter.

CHARGES ON ASSETS

As at 30 June 2020, the borrowings of the Group were secured as follows:

  1. Approximately US$4,579.8 million (31 December 2019: US$4,852.1 million) from China Development Bank, Industrial and Commercial Bank of China Limited, BOC Sydney and The Export-Import Bank of China was secured by share security over the entire share capital of MMG South America Management Co Ltd and each of its subsidiaries including MLB, a debenture over the assets of MMG South America Management Co Ltd, an assets pledge agreement and production unit mortgage in respect of all of the assets of MLB, assignments of shareholder loans between MMG South America Management Co Ltd and its subsidiaries and security agreements over bank accounts of MLB. Approximately US$354.0 million (31 December 2019: US$469.0 million) of these borrowings are guaranteed on a several basis by China Minmetals Non-ferrous Metals Holding Company Limited and China Minmetals Corporation Limited, Guoxin International Investment Corporation Limited and CITIC Corporation Limited in proportion to the respective shareholdings of MMG SA, Elion Holdings Corporation Limited and Citic Metal Peru Investment Limited in the Company.
  2. Approximately US$370.4 million (31 December 2019: US$398.6 million) from China Development Bank and BOC Sydney was substantively secured by the shares and assets of MMG Dugald River Pty Ltd (MMG Dugald River). This consists of a charge over the shares in MMG Dugald River, a real property mortgage over all of the interests in land of MMG Dugald River, a general security agreement in respect of all of the assets of MMG Dugald River, and specific security over certain assets owned by MMG Australia Limited

27

MANAGEMENT DISCUSSION AND ANALYSIS CONTINUED

relating to the Dugald River project, and a featherweight charge over all of MMG Australia Limited's other assets.

  1. Approximately US$63.4 million (31 December 2019: nil) from ICBC Peru Bank, Banco de Crédito del Peru and Scotiabank Peru was secured by mine fleet equipment procured under asset finance arrangements.

FUTURE PROSPECTS

MMG continues to pro-actively respond to the COVID-19 pandemic, working closely with national authorities to protect the health and safety of its employees, host communities and other stakeholders.

Despite the challenges presented by the pandemic and noting ongoing uncertainty, MMG continues to expect to produce between 68,000 and 75,000 tonnes of copper cathode at Kinsevere, and between 225,000 and 245,000 tonnes of zinc at its Dugald River and Rosebery operations in 2020.

All guidance for Las Bambas has been withdrawn due to uncertainty regarding the impacts of the COVID-19 pandemic in Peru. The Company will provide updated production and cost guidance for Las Bambas once there is greater operational certainty. In the interim, the Company continues to effectively work within constraints presented by the pandemic, maximising efficiency at site and working to achieve an efficient ramp-up and resumption of normal operations, as circumstances allow.

Total capital expenditure of between US$650.0 million and US$700.0 million was forecast for 2020, of which approximately US$600.0 million was attributable to Las Bambas, inclusive of approximately US$230.0 million of capitalised mining. As noted above, the Company has withdrawn guidance as it relates to Las Bambas, however anticipates that full year 2020 capital expenditure for that site will be approximately US$100.0 million below levels originally expected. Given the non-discretionary nature of the majority of Las Bambas' capital expenditure, it is likely that any savings will be temporary. The Company maintains its capital expenditure forecast for other sites.

MMG continues to maintain a favourable outlook for the DRC and continues to progress a feasibility study for the addition of a sulphide ore and cobalt processing circuit. A decision on this project is expected in the second half of 2020. Should it proceed, it will add significant life and value to MMG's operations in the DRC. It will also provide an entry for the Company into the cobalt market and enhance optionality for future potential investments in country. Consistent with this, MMG also continues its exploration activity in the DRC, particularly on tenements held inside a 50-kilometre radius of the Kinsevere mine.

In relation to is Australian operations, the Company continues to focus on de-bottlenecking and optimisation works at Dugald River, which are anticipated to increase mine capacity from 1.75 million to over 2 million tonnes per annum by 2022. This will pave the way for targeted zinc equivalent production of at least 200,000 tonnes annually from 2022. At Rosebery, resource extension drilling has provided encouraging early results. MMG remains committed to extending the operating life of this important asset.

MMG currently has no future plans for material investments or capital assets sanctioned by the Board, other than those detailed in this report or announced to the market.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1. GENERAL INFORMATION AND INDEPENDENT REVIEW

MMG Limited (the "Company") is a limited liability company and was incorporated in Hong Kong on 29 July 1988. The address of its registered office is Unit 8506A, Level 85, International Commerce Centre, 1 Austin Road West, Kowloon, Hong Kong. The principal place of business of the Company is disclosed in the Corporate Information section to the Group's 2020 Interim Report.

The Company is an investment holding company and is listed on the main board of The Stock Exchange of Hong Kong Limited ("HKEx"). The Company and its subsidiaries (the "Group") are engaged in the exploration, development and mining of copper, zinc, gold, silver and lead deposits around the world.

The condensed consolidated interim financial statements for the six months ended 30 June 2020 are presented in United States Dollars ("US$" or "USD") unless otherwise stated and have been approved for issue by the Board of Directors of the Company (the "Board") on 19 August 2020.

The financial information relating to the year ended 31 December 2019 that is included in these condensed consolidated interim financial statements as comparative information does not constitute the Company's statutory annual consolidated financial statements for that year but is derived from those financial statements. Further information relating to these statutory financial statements required to be disclosed in accordance with section 436 of the Hong Kong Companies Ordinance is as follows:

  • The Company has delivered the financial statements for the year ended 31 December 2019 to the Registrar of Companies as required by section 662(3) of, and Part 3 of Schedule 6 to, the Hong Kong Companies Ordinance.
  • The Company's auditor has reported on those financial statements. The auditor's report was unqualified; did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying its report; and did not contain a statement under sections 406(2), 407(2) or (3) of the Hong Kong Companies Ordinance.

The condensed consolidated interim financial statements for the six months ended 30 June 2020 are unaudited and have been reviewed by the audit committee and the external auditor of the Company.

2. BASIS OF PREPARATION

These condensed consolidated interim financial statements for the six months ended 30 June 2020 have been prepared in accordance with applicable disclosure requirements of Appendix 16 to the Rules Governing the Listing of Securities on the HKEx and Hong Kong Accounting Standard ("HKAS") 34 Interim Financial Reporting, issued by the Hong Kong Institute of Certified Public Accountants ("HKICPA"). The condensed consolidated interim financial statements should be read in conjunction with the annual consolidated financial statements for the year ended 31 December 2019, which have been prepared in accordance with the Hong Kong Financial Reporting Standards ("HKFRS") issued by the HKICPA.

The condensed consolidated interim financial statements have been prepared on a going concern basis which assumes the continuity of normal business activity and the realisation of assets and the settlement of liabilities in the normal course of business. Management continues to closely monitor the liquidity position of the Group, which includes the sensitised analysis of forecast cash balances for key financial risks (including commodity and foreign exchange risks) over the short and medium term to ensure adequate liquidity is maintained.

For the six-month period ended 30 June 2020, the Group generated a net loss of US$182.7 million (2019:

US$73.0 million), primarily due to the outbreak of COVID-19 which has adversely impacted production at Las Bambas and led to lower copper and zinc prices.

38

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

At 30 June 2020, the Group had net current liabilities of US$738.0 million (31 December 2019: US$445.6

million) and generated net operating cash inflows of US$366.6 million (2019: US$290.0 million) and total net

cash outflows of US$146.6 million (2019: US$359.9 million), after investing and financing cash flows. Cash flow forecasts, which assume the continuity of normal business activity, indicate that the Group will only have sufficient liquidity to meet its operational, existing contractual debt service and capital expenditure requirements for the 12 month period from the approval of the condensed consolidated interim financial statements if it is able to defer a US$700.0 million loan repayment that falls due in July 2021. This amount falls due under a US$2,262.3 million loan that was established in 2014 between Top Create Resources Limited ("Top Create"), a subsidiary of China Minmetals Corporation ("CMC"), and MMG South America Company Limited. Consistent with past practice when amounts under this loan have fallen due, Top Create has indicated a willingness to further defer the US$700.0 million 2021 repayment, before it falls due.

In addition, the Directors of the Company (the "Directors") note the following considerations, relevant to the Group's ability to continue as a going concern:

  • At 30 June 2020, total cash and cash equivalents of US$70.9 million (31 December 2019: US$217.5 million) were held by the Group;
  • The ongoing trading support of the China Minmetals Non-ferrous Metals Co., Ltd ("CMN") and joint venture partner CITIC Metal Peru Investment Limited ("CITIC") each as direct or indirect off-takers of Las Bambas production. This has been demonstrated by an agreement entered into with each party for early payment on cargos already shipped and invoiced as well as prepayments for inventory held at both port and site. Early payment and prepayments are permitted up to an aggregate amount of US$200.0 million until 31 December 2020, allocated to each party in their respective off-take proportions;
  • At 30 June 2020, MMG South America Management Company Limited and its subsidiaries ("Las Bambas Joint Venture Group") had available undrawn debt facilities of US$210.0 million (31 December 2019: US$350.0 million) under a US$175.0 million revolving credit facility provided by
    Bank of China, Sydney Branch ("BOC Sydney") and a US$175.0 million revolving credit facility provided by ICBC, Luxembourg Branch ("ICBC Luxembourg"), both of which mature in August 2022;
  • The Group has positive relationships with its external financiers, who continue to provide strong support. This has been recently demonstrated by their willingness to advance additional lines of credit to the Group. The Group is also in discussions with its lenders to refinance debt facilities that will be maturing in the second half of 2020. These facilities will be in addition to those executed in August 2020;
  • The strong ongoing support of the Group's major shareholder, CMC. This has been demonstrated by an agreement entered into in May 2020 with Top Create, whereby an existing US$100.0 million working capital facility was increased to US$200.0 million, and the maturity date extended from April 2021 to October 2021. At 30 June 2020 this facility was undrawn (31 December 2019: nil drawn). In addition, in June 2020 Top Create provided a new US$300.0 million revolving credit facility, which will mature in December 2020. At 30 June 2020 this facility was drawn to US$200.0 million. Drawings under this facility were used to repay amounts outstanding under a US$300 million revolving credit facility provided by Industrial and Commercial Bank of China Ltd ("ICBC"), Melbourne Branch. The
    ICBC facility, which was scheduled to mature in December 2020, was subsequently cancelled by MMG; and
  • In the event forecast cash flow is not achieved or that existing or new debt facilities are insufficient or not obtained within time, the Group has the support of its major shareholder, CMC. In this circumstance, support to the Group may be in the form of providing additional debt facilities, deferral of debt service and repayment obligations in relation to existing shareholder loans from CMC, or through further equity contributions.

39

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

As a result, the Directors are of the view that the Group will be able to meet its debts as and when they fall due and accordingly the Directors have prepared the condensed consolidated interim financial statements on a going concern basis.

2.1 Accounting policies

The accounting policies applied are consistent with those of the consolidated financial statements for the year ended 31 December 2019, except for the adoption of new amendments to the existing standards as set out below.

    4. Effective date to be determined

2.2 Derivative financial instruments and hedge accounting

Derivatives are initially recognised at fair value at the date when derivative contracts are entered into and are subsequently remeasured to their fair value at the end of the reporting period. The resulting gain or loss is recognised in profit or loss unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

As of the reporting date, the Group has designated a derivative instrument (being an interest rate swap and floor) as a hedging instrument for cash flow hedge purposes.

At the inception of the hedging relationship the Group documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking the hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Group documents whether the hedging instrument is effective in offsetting changes in cash flows of the hedged item attributable to the hedged risk.

40

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

For the purpose of determining whether a forecast transaction (or a component thereof) in a cash flow hedge is highly probable, the Group assumes that interest rate benchmark on which the hedged cash flows are based is not altered as a result of interest rate benchmark reform.

Assessment of hedging relationship and effectiveness

For hedge effectiveness assessment, the Group considers whether the hedging instrument is effective in offsetting changes in cash flows of the hedged item attributable to the hedged risk, which is when the hedging relationships meet all of the following hedge effectiveness requirements:

  • there is an economic relationship between the hedged item and the hedging instrument;
  • the effect of credit risk does not dominate the value changes that result from that economic relationship; and
  • the hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Group actually hedges and the quantity of the hedging instrument that the entity actually uses to hedge that quantity of hedged item.

In assessing the economic relationship between the hedged item and the hedging instrument the Group assumes that the interest rate benchmark on which the hedged cash flows and/or hedged risk are based, or the interest rate benchmark on which the cash flows of the hedging instrument are based, is not altered as a result of interest rate benchmark reform.

The effective portion of changes in the fair value of the hedging instrument designated as cash flow hedges is recognised in other comprehensive income and accumulated under the heading of cash flow hedge reserve, limited to the cumulative change in fair value of the hedged item from inception of the hedge. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss, and is included in the 'finance income' or 'finance costs' line item.

For the purpose of reclassifying the amount of accumulated in the cash flow hedge reserve in order to determine whether the hedged future cash flows are expected to occur, the Group assumes the interest rate benchmark on which the hedged cash flows are based is not altered as a result of interest rate benchmark reform.

2.3 Critical estimates and judgements

The preparation of condensed consolidated interim financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Actual results may differ from these estimates.

Significant judgement and estimates applied by management in assessing recoverability of non-financial assets have been disclosed in Note 9.

Other than the above, the significant judgements made by management in applying the Group's accounting policies and the key sources of estimation uncertainty, namely mine rehabilitation, restoration and dismantling obligations, mineral resources and ore reserves estimates, deferral of waste removal costs and taxes, were the same as those that applied to the consolidated financial statements for the year ended 31 December 2019.

41

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

3. SEGMENT INFORMATION

HKFRS 8 "Operating Segments" requires operating segments to be identified on the basis of internal reports about operations of the Group that are regularly reviewed by the chief operating decision-maker ("CODM") in order to allocate resources to the segment and assess its performance.

The Company's Executive Committee has been identified as the CODM. The Executive Committee reviews the Group's internal reporting of these operations in order to assess performance and allocate resources.

The Group's reportable segments are as follows:

Las Bambas

The Las Bambas mine is a large open-pit, scalable, long-life copper and

moly mining operation with prospective exploration options. It is located

in the Cotabambas, Apurimac region of Peru.

Kinsevere

Kinsevere is an open-pit copper mining operation located in the Haut-

Katanga Province of the Democratic Republic of the Congo ("DRC").

Dugald River

The Dugald River mine is an underground zinc mining operation located

near Cloncurry in North West Queensland.

Rosebery

Rosebery is an underground polymetallic base metal mining operation

located on Tasmania's west coast.

Other

Includes exploration projects, mine sites under care and maintenance

and corporate entities in the Group.

A segment result represents the EBIT by each segment. This is the measure reported to the CODM for the purposes of resource allocation and assessment of segment performance. Other information provided, except as disclosed in the following paragraph, to the CODM is measured in a manner consistent with that in these condensed consolidated interim financial statements.

Segment assets exclude current income tax assets, deferred income tax assets and net inter-segment receivables. Segment liabilities exclude current income tax liabilities, deferred income tax liabilities and net inter-segment loans. The excluded assets and liabilities are presented as part of the reconciliation to total consolidated assets or liabilities.

Impairment review of non-current assets and goodwill

In accordance with the Group's accounting policies and processes, the Group performs its impairment testing annually at 31 December. Cash Generating Units ("CGUs") are reviewed at each reporting period to determine whether there is an indication of impairment or impairment reversal. Where an indicator of impairment or impairment reversal exists, a formal estimate of the recoverable amount is made at the reporting period.

Indicators of impairment were noted for Las Bambas due to below plan performance impacted by a number of factors including lower production due to COVID-19 pandemic related restrictions and lower copper prices.

Indicators of impairment were noted for Kinsevere due to the political and legislative environment in the DRC and the decline in copper price during the period. An impairment write-down of US$105.0 million (post-tax basis) was recognised in relation to the Kinsevere CGU at 31 December 2019.

In respect of Dugald River, an impairment loss was recognised in 2015. Management has reviewed the operational performance and considered the operation's sensitivity to a range of factors including zinc price, AU$ to US$ exchange rate, throughput, grade, recovery and operational and capital expenditure and concluded that there is currently no reliable indicator that the impairment could be reversed.

No impairment indicators were noted in respect of Rosebery.

(i) Approach to recognition of an impairment loss

An impairment is recognised when the carrying amount exceeds the recoverable amount. The recoverable amount of each CGU has been estimated using its fair value less costs of disposal ("Fair Value"), which is consistent with the approach from the prior year.

(ii) Key assumptions

The key assumptions impacting the discounted cash flow models used to determine the Fair Value include:

  • Commodity prices;
  • Operating costs;
  • Capital requirements;
  • Real post-tax discount rates;
  • Foreign exchange rates;
  • Reserves and Resources and exploration targets;
  • Optimisation of operational activity and productivity; and
  • Rehabilitation timing.

In determining some of the key assumptions, management considered external sources of information where appropriate.

Commodity price and exchange rate assumptions are based on the latest internal forecasts benchmarked to analyst consensus forecasts. The long-term cost assumptions are based on actual costs adjusted for planned operational changes and input cost assumptions over the life of mine.

Commodity price estimates included in the three-year budget cash flows used the latest forecast metal prices. The long-term price assumed for copper is US$3.21 per pound, unchanged from 2019.

The real post-tax discount rates used in the Fair Value estimates for the Las Bambas and Kinsevere CGU's are unchanged from 2019; that is, 7% and 10% respectively.

Management considers the estimates applied in this impairment assessment are reasonable. However, such estimates are subject to significant uncertainties and judgements. Refer to (iv) below for sensitivity analysis.

48

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

  1. Valuation methodology Las Bambas

The Las Bambas Fair Value is determined through the 2019 Life of Asset ("LoA") discounted cash flows that was updated for known changes and also supported by comparable transaction multiples. The valuation contains the current operation and further regional exploration targets included in the initial valuation to acquire the mine in 2014. The cash flows assume additional capital investment in the processing plant as well as expected cost reductions from operational improvement programs underway. Future cash flow forecasts include estimates for the cost of obtaining access to land where the rights do not currently exist.

In response to the COVID-19 pandemic, the Peruvian government implemented a State of Emergency from 15 March 2020 to 30 June 2020. Although mining and processing operations have continued during this period, the level of activity and compliance to original mine plans has been impacted. Production guidance for 2020 was withdrawn on 13 April 2020. Management is working on a range of scenarios for recovery in order to plan a return to normal operations. Limitations imposed by the COVID-19 related State of Emergency may impact the timing of environmental and drilling permits.

The impairment assessment of the Las Bambas' CGU at 30 June 2020 did not result in the recognition of impairment. The 2020 LoA is being completed in the second half of the year during the mine planning process and will be used to test impairment at 31 December 2020.

Kinsevere

An impairment write-down of US$150.0 million pre-tax (US$105.0 million on a post-tax basis) was recognised in relation to the Kinsevere CGU at 31 December 2019. The impairment was recognised as a result of operational challenges and management's best estimate of risks associated with political and legislative matters. The impairment resulted in a reduction to the carrying value of the oxide related assets to more accurately reflect the remaining life of the current oxide operation.

As disclosed in the consolidated financial statements for the year ended 31 December 2019, the DRC Government passed significant changes to the DRC 2002 Mining Code (2018 Mining Code) in March 2018. In light of the adverse impact the 2018 Mining Code represents to Kinsevere mine, the Group along with other industry participants has continued to engage in discussion with the DRC Government seeking to negate or reduce negative financial outcomes.

Whilst there has been some progress including agreement with the DRC Government on a substantial amount of historical value added tax ("VAT") receivable in 2019, uncertainties continue to exist in relation to the recovery of historic and future VAT balances.

The Kinsevere Fair Value at 30 June 2020 is based upon the Kinsevere Development Project Feasibility Study, which includes the current oxide operations and options to extend the life of Kinsevere, including the addition of a sulphide ore and cobalt processing circuit alongside the existing oxide circuit. The Company expects to reach a final investment decision on this project during the second half of 2020.

The impairment assessment of the Kinsevere CGU at 30 June 2020 did not result in the recognition of any further impairment or reversal of impairment. In the event that the Kinsevere Development Project does not progress to execution, there would likely be a further impairment to the carrying value of Kinsevere.

49

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

(iv) Sensitivity analysis

Commodity prices, the level of production activity as well as the success of converting Reserves and Resources and increasing the resource estimates over the lives of mines are key assumptions in the determination of Fair Value. Due to the number of factors that could impact production activity, such as processing throughput, changing ore grade and/or metallurgy and revisions to mine plans in response to physical or economic conditions, no quantified sensitivity has been determined. Changes to these assumptions may however result in an impact on the Fair Value and result in impairment in future.

A sensitivity analysis is presented below for both Las Bambas and Kinsevere. The sensitivities assume that the specific assumption moves in isolation, whilst all other assumptions are held constant. In reality, a change in one of the aforementioned assumptions may accompany a change in another assumption which may have an offsetting impact. Action is also usually taken to respond to adverse changes in economic assumptions that may mitigate the impact of any such change.

Las Bambas

The key assumptions to which the calculation of recoverable amount for Las Bambas is most sensitive are copper price, operating costs, land access (including permitting delays and the amount and timing of exploration potential to be realised) and discount rate. An adverse change of 5% in copper price over the remaining mine life would decrease the recoverable amount by approximately US$1,000 million. An increase of 1% to the discount rate would decrease recoverable amount by approximately US$800 million. An adverse change of 5% in operating costs would decrease the recoverable amount by approximately US$400 million. The impact of delays in land access or the amount or timing of exploration potential realised would result in a revision to the mine plan in response to these conditions. The occurrence of one or more of the above assumptions in isolation, without a change in other assumptions which may have an offsetting impact, would result in the carrying value of Las Bambas exceeding the recoverable value.

Kinsevere

The key assumptions to which the calculation of Fair Value for Kinsevere is most sensitive are copper price, the successful expansion of the processing plant to process sulphide ore and cobalt, the application of the 2018 Mining Code as outlined above and cobalt pricing. An adverse change of 5% in copper price over the remaining mine life would further decrease the recoverable amount by approximately US$100 million. An adverse change of 5% in cobalt price over the remaining mine life would further decrease the recoverable amount by approximately US$25 million. In the event that the next phase of the development of Kinsevere does not progress to execution, there is likely to be a further impairment to the assets of Kinsevere.
