First Quantum Minerals Reports Fourth Quarter And Year-End 2021 Results

TORONTO, Feb. 15, 2022 - First Quantum Minerals Ltd. ("First Quantum" or the "Company") (TSX: FM) today reported results for the three months and year-ended December 31, 2021. For the three months ended December 31, 2021 ("Q4"), the Company reported net earnings attributable to shareholders of the Company of $247 million ($0.36 per share), adjusted earnings¹ of $306 million ($0.44 per share²), and cash flows from operating activities of $760 million ($1.10 per share²). For the year-ended 2021, the Company reported net earnings attributable to shareholders of the Company of $832 million ($1.21 per share), adjusted earnings¹ of $826 million ($1.20 per share²), and cash flows from operating activities of $2,885 million ($4.19 per share²).

"First Quantum's operations continue to demonstrate resilience in dealing with the challenges brought about by the COVID-19 pandemic and new variants as they emerge. We are in a period of solid cash flow generation for the Company and while debt reduction remains a priority, we are pleased to cautiously commence increased capital returns to our shareholders with our new dividend framework. We have released our inaugural Climate Change report which recognizes our obligation to mine responsibly and to report on our actions to address climate change," commented Philip Pascall, Chairman and CEO. "I am grateful for the dedication and commitment of the entire team at First Quantum and for the support of Governments and communities in our host countries. It is with these efforts and this support that First Quantum is placed in a strong position for 2022 and beyond."

FOURTH QUARTER SUMMARY

• Fourth quarter financial results benefitted from higher sales volumes and a higher realized copper price² of $4.08 per lb as the Company's hedge profile continued to decline, partially offset by higher costs. The Company's exposure to the strong copper price environment is expected to continue to improve with the declining profile of the hedge book with no new additional copper hedges were entered into during the fourth quarter. On the basis of continued strong operational performance, the Company anticipates continued strong future cash flow and expects to be in a position to continue its debt reduction program, to advance growth programs, to support Environmental, Social & Governance ("ESG") initiatives and to cautiously increase dividend payments in 2022.
• Q4 2021 copper production totalled 201,823 tonnes, taking the full year production to 816,435 tonnes, the highest annual copper production in First Quantum's history. Through advancement of its brownfield portfolio, the Company sees a path to 1 million tonnes of copper production.
• Copper C1 cash costs² averaged $1.39 per lb during the quarter. While operating costs are facing inflationary pressures, Q4 2021 was also impacted by higher electricity costs due to regular maintenance shutdown works to Unit 1 of the power station at Cobre Panama. During the quarter, however, there was a non-recurring reduction in provisions at Kansanshi from the Zambian Electricity Supply Corporation Limited ("ZESCO") arbitration case that was settled in December 2021.

² Adjusted earnings (loss) per share, cash flows from operating activities per share, realized metal prices, and copper C1 cash costs (C1) are non-GAAP ratios which do not have a standardized meaning prescribed by IFRS and might not be comparable to similar financial ratios disclosed by other issuers.

• Cash flow from operating activities was $760 million for Q4 2021 and cumulatively $2,885 million for the full year 2021. Net debt¹ decreased by $249 million during the quarter, bringing the balance down to $6,053 million as at December 31, 2021. The Company expects to achieve the previously announced $2 billion debt reduction target in H1 2022 and has increased the short to medium term target by an additional $1 billion. A new dividend policy was announced on January 17, 2022.
  

Q4 2021 OPERATIONAL HIGHLIGHTS

As previously reported, fourth quarter total copper production of 201,823 tonnes was down 4% from Q3 2021. Production declined quarter-over-quarter as a result of expected lower ore grades at Cobre Panama while production at Kansanshi and Sentinel remained consistent with Q3 2021 levels. Copper C1 cash costs² averaged $1.39 per lb during the quarter, up 10% from the previous quarter, as the company continued to experience cost increases related to freight and fuel. For the full year 2021, First Quantum achieved its highest ever annual copper production of 816,435 tonnes, a 5% increase from 2020, attributable to record production at Cobre Panama and the resilience of the other operations. Copper C1 cash costs² averaged $1.30 per lb for the year, the midpoint of the Company's guidance range of $1.25 to $1.35 per lb.

• Cobre Panama produced 80,030 tonnes of copper in Q4 2021, a decrease of 8% quarter-over-quarter principally due to expected lower ore grades based on the mine plan. During the quarter, Unit 1 of the power plant continued maintenance shutdown works, which were completed in late January. Although replacement power for Unit 1 was sourced from the grid, a 7-day unplanned shutdown of Unit 2 impacted total tonnes milled during the quarter. However, Cobre Panama set a record in monthly copper production in October. Copper C1 cash cost² for the quarter was $1.57 per lb, a 24% increase from Q3 2021 as electricity was drawn from the grid at spot rates during the period of maintenance to the power station.
• Kansanshi copper production in the fourth quarter of 2021 was 51,939 tonnes, a slight improvement over Q3 levels on improved ore grades. Copper C1 cash costs² were $0.79 per lb in Q4 2021, down 26% from the previous quarter. Copper C1 cash costs during the quarter benefitted from a reduction on operational provisions following the conclusion of the arbitration case on electricity prices charged by ZESCO in December 2021. This is a one-time benefit that is not expected to recur in future quarters.
• Sentinel delivered its best quarterly production of the year with 60,197 tonnes of copper produced on record quarterly throughput rates equivalent to 60 million tonnes per annum ("Mtpa"). Sentinel copper C1 cash cost² in the fourth quarter of $1.51 per lb was up 10% quarter-over-quarter, reflecting inflationary pressures such as higher consumables, fuel and labour costs.
• Copper sales in Q4 2021 totalled 213,087 tonnes, up from 194,278 tonnes in Q3 2021. In the fourth quarter, there was a recovery in sales volumes at Kansanshi and Sentinel as a number of planned shipments from the third quarter were rolled into the fourth quarter. Logistical challenges for Zambian sales are expected to continue throughout the first quarter of 2022.
• Total gold production for Q4 2021 was 74,945 ounces, a 4% decrease from the previous quarter, mainly attributable to lower gold production at Cobre Panama. Gold sales volumes of 79,403 ounces for the fourth quarter remained fairly consistent with the prior quarters in the year.
• Ravensthorpe had its lowest quarterly nickel production of the year at 3,385 contained tonnes. Fourth quarter production was impacted by the delayed transition to the Shoemaker Levy orebody and unplanned maintenance at the power plant main steam pipe. However, commissioning of the Shoemaker Levy conveyor was completed later in the quarter and the resulting material handling performance and beneficiation upgrade was improved compared to the Hale Bopp ore, in line with expectations. Skilled labour availability and high sulphur prices remain a challenge.

The new $2.925 billion Facility comprises a $1.625 billion Term Loan Facility and a $1.3 billion Revolving Credit Facility, maturing in 2025 and is syndicated to a group of long-standing relationship banks of First Quantum. The Facility was used to fully prepay and cancel amounts outstanding on the existing facility, to fully prepay and cancel a bilateral bank facility for $175 million and for general corporate purposes. Repayments on the term loan will commence in December 2022. The Facility has a single Net debt³ to EBITDA ratio covenant set at 3.5 times over the Facility term.
• Note redemption: On December 7, 2021, the Company redeemed $600 million of the 2023 Notes at a redemption price of 101.813%. The portion of the outstanding 2023 Notes to be redeemed was allocated on a lottery drawing basis at the redemption plus accrued and unpaid interest.
• As previously announced, with the company on track to meet the previously announced $2 billion debt reduction target during the first half of 2022, the target for debt reduction in the short to medium term has increased by $1 billion.
• The Company has declared a final dividend of $0.005 Canadian dollar ("CDN") per share, in respect of the financial year-ended December 31, 2021. The final dividend together with the interim dividend of CDN$0.005 per share is a total of CDN$0.01 per share for the 2021 financial year.
• A new dividend policy was also adopted by the Company. The Company intends to pay, on a semi-annual basis, a performance dividend (the "Performance Dividend") that represents, in the aggregate, 15% of available cash flows generated after planned capital spending and distributions to non-controlling interests. It is expected that a minimum annual base dividend of CDN$0.10 per share consisting of semi-annual dividends of CDN$0.05 per share will be part of the Performance Dividend.
• Copper price hedges: At December 31, 2021, all of the Company's unmargined copper forward sales contracts have matured, with no new hedges put in place. At February 15, 2022, the Company had 40,000 tonnes of unmargined zero cost copper collar sales contracts with maturities to June 2022 at weighted average prices of $3.63 per lb to $4.68 per lb outstanding. Copper sales in the fourth quarter were 24% hedged. Approximately 5% of expected copper sales for the next 12 months are hedged to unmargined zero cost collar sales contracts.

2022 to 2024 GUIDANCE UPDATE

Three-year guidance on production, C1 cash costs¹, AISC¹ and capital expenditures that was previously disclosed on January 17, 2022 remains unchanged. Copper and nickel production are forecast to grow to 850,000 to 910,000 tonnes and 40,000 to 50,000 tonnes, respectively, by 2024. Capital cost guidance has been guided to $1,250 million in 2022 and 2023 and $1,375 million in 2024.

• Cobre Panama is expected to produce 330,000 to 360,000 tonnes of copper and 135,000 to 150,000 ounces of gold in 2022. Mill throughput is expected to ramp up over the course of 2022 to achieve between 85 and 90 Mtpa. For 2022 as a whole, grades and recoveries are expected to be consistent with 2021 levels but will fluctuate from quarter to quarter. The three-year guidance period for Cobre Panama includes the CP100 Expansion, which includes a new primary crushed ore screening facility, process water upgrades and the addition of a sixth ball mill. Completion of construction works and commencement of commissioning is targeted for the first quarter of 2023 to allow for a ramp up of production over the course of the year and achieve a throughput rate of 100 Mtpa by the end of 2023. A Letter of Intent was signed for incremental electrical supply for the CP100 Expansion, approximately 60-80MW, and is expected to be renewable power, specifically hydroelectricity, sourced from the Panamanian grid.
• At Kansanshi, production in 2022 is expected to range from 190,000 to 210,000 tonnes of copper and 120,000 to 130,000 ounces of gold. Based on the current mine plan at Kansanshi, while processed ore is expected to be slightly higher in 2022 relative to 2021, grades are expected to decline over the course of the year from Q4 2021 levels. For the three-year guidance period, copper and gold production in 2024 includes some limited production associated to the S3 expansion, with the development and timing still subject to Board approval.
• At Sentinel, copper production in 2022 is expected to be between 260,000 to 280,000 tonnes. Grade is expected to improve from 2021 levels throughout 2022 as higher-grade ore is exposed in both the Stage 1 and Stage 2 pits. Construction of the fourth in-pit crusher was completed in the December 2021 and commissioning was completed in January 2022, which will enable the plant to achieve throughput of 62 Mtpa in 2022.
• 2022 copper production guidance from Other sites is expected to be 30,000 tonnes.
• Nickel production in 2022 from Ravensthorpe is expected to be 25,000 to 30,000 tonnes with major shutdowns and descales of autoclaves scheduled in March and August of this year. Nickel production for the three-year guidance period includes Enterprise, with first production assumed during 2023. The development timeline for Enterprise is expected to be approximately twelve months and still subject to Board approval.
• C1 cash cost² guidance over 2022 to 2024 period for both copper and nickel remains unchanged and reflects recent inflationary and commodity price pressures as well as movement in foreign exchange rates, particularly in Zambia. AISC guidance also reflects higher royalties in Zambia related to copper prices as well as an increase in sustaining capital expenditure. At this stage, guidance assumes no change in royalties in Panama. Copper C1 cash cost² and AISC² guidance for 2024 includes some limited contribution from the S3 expansion at Kansanshi. Nickel unit cost guidance does not include Enterprise. By 2024, nickel C1 cash costs² at Enterprise are expected to range $4.25/lb to $5.25/lb.
• Guidance on 2022 to 2024 capital expenditures remains unchanged. Within the total project capital expenditure guidance of $2,210 million over the three-year period, approximately $1,000 million relates to Kansanshi, $830 million to Cobre Panama, $60 million to Enterprise and $15 million to Guelb Moghrein.

PANAMA LAW 9 UPDATE

In July 2021, the Government of Panama ("GOP") announced the appointment of a high-level commission of senior government ministers and officials, chaired by the Minister of Commerce, to discuss the Company's concession contract. In September 2021, the Supreme Court upheld its ruling in respect of the clarification motions presented by the Company to the Court in relation to its Law 9 decision announced in September 2018 and the ruling was gazetted in the fourth quarter. We understand that the upholding of the unconstitutionality ruling against Law 9 of 1997 does not have retroactive effects, pursuant to article 2573 of the Code of Judicial Proceedings of Panama, therefore the approval of the mining concession contract which occurred in 1997 with the enactment of Law 9, remains unaltered, providing operation continuity as per status quo. In September 2021, the Ministry of Commerce publicly announced the culmination of the high-level formal discussions on two topics being environmental and labour matters.

During January 2022, the GOP tabled a new proposal, namely that the GOP should receive $375 million in benefits per year from Cobre Panama and that the existing revenue royalty will be replaced by a gross profit royalty. The parties continue to finalize the details behind these principles, including the appropriate mechanics that would achieve this outcome, the necessary protections to the business for downside copper price and production scenarios and to ensure that the new contract and legislation are both durable and sustainable.

Once an agreement is concluded and the full contract is documented, it is expected that the newly drafted legislation will be put to the National Assembly. The Company welcomes the transparency of the robust ministerial commission process and is hopeful that this matter can be concluded shortly.

ZESCO RESOLUTION

In the fourth quarter of 2021, the Company received a favourable resolution on the case that commenced in June 2018 between ZESCO and Kansanshi.

The arbitration hearing took place on August 22, 2018 and concluded in July 2021 with the Tribunal issuing its award in November 2021. The Tribunal found in favour of Kansanshi on the key issues including the appropriate tariff and the return to Kansanshi of the funds held in the segregated account pursuant to the Order. In December 2021, the Tribunal awarded Kansanshi its costs of the arbitration and rejected ZESCO's application for interpretation of various parts of the Tribunal's award.

Despite this dispute, the Company's operations generally maintain a constructive relationship with ZESCO, particularly with regards to the management of technical and supply issues. Operational and technical dialogue between the parties is expected to continue in the normal course.

COVID-19

The ongoing challenges presented by COVID-19 have continued throughout the fourth quarter, with the Omicron variant present on several sites. Fortunately, employees and neighbouring communities are not experiencing as severe symptoms from this wave as previous variants. The focus for this quarter has been to maximize vaccination rates and plan booster vaccination campaigns for 2022.

The Company continues to maintain strict health and sanitary protocols to minimize transmission and support the government health authorities. We continue to work with local communities to develop support processes and encourage vaccination. The Company has also redesigned ways of working, with staggered rosters, remote working and bubble concepts on site to continue operations while limiting the potential spread.

As cases are identified amongst the workforce, they are contained and isolated according to the established protocols and in coordination with local health authorities, with limited impact to operations. The Company continues to employ measures to ensure minimal spread, and the health and well-being of our workforce continues to be a priority.

REGULATORY DISCLOSURES

EBITDA¹, ADJUSTED EARNINGS¹ AND ADJUSTED EARNINGS PER SHARE²

EBITDA¹, adjusted earnings¹ and adjusted earnings per share² exclude certain impacts which the Company believes are not reflective of the Company's underlying performance for the reporting period. These include impairment and related charges, foreign exchange revaluation gains and losses, gains and losses on disposal of assets and liabilities, one-time costs related to acquisitions, dispositions, restructuring and other transactions, revisions in estimates of restoration provisions at closed sites, debt extinguishment and modification gains and losses, the tax effect on unrealized movements in the fair value of derivatives designated as hedged instruments, and adjustments for expected phasing of Zambian VAT receipts.

REALIZED METAL PRICES²

Realized metal prices are used by the Company to enable management to better evaluate sales revenues in each reporting period. Realized metal prices are calculated as gross metal sales revenues divided by the volume of metal sold in lbs. Net realized metal price is inclusive of the treatment and refining charges (TC/RC) and freight charges per lb.

OPERATING CASHFLOW PER SHARE²

In calculating the operating cash flow per share, the operating cash flow calculated for IFRS purposes is divided by the basic weighted average common shares outstanding for the respective period.

NET DEBT³

Net debt comprises unrestricted cash and cash equivalents, bank overdrafts and total debt.

¹Adjusted earnings (loss) and EBITDA non-GAAP financial measures which do not have a standardized meaning prescribed by IFRS and might not be comparable to similar financial measures disclosed by other issuers.

³ Net debt is a supplementary financial measure which does not have a standardized meaning prescribed by IFRS and might not be comparable to similar financial measures disclosed by other issuers.

CASH COST², ALL-IN SUSTAINING COST², TOTAL COST²

The consolidated cash cost (C1)², all-in sustaining cost (AISC) ² and total cost (C3) ² presented by the Company are measures that are prepared on a basis consistent with the industry standard definitions by the World Gold Council and Brook Hunt cost guidelines but are not measures recognized under IFRS. In calculating the C1 cash cost², AISC² and C3², total cost for each segment, the costs are measured on the same basis as the segmented financial information that is contained in the financial statements.

C1 cash cost includes all mining and processing costs less any profits from by-products such as gold, silver, zinc, pyrite, cobalt, sulphuric acid, or iron magnetite and is used by management to evaluate operating performance. TC/RC and freight deductions on metal sales, which are typically recognized as a component of sales revenues, are added to C1 cash cost to arrive at an approximate cost of finished metal.

AISC² is defined as cash cost (C1) ² plus general and administrative expenses, sustaining capital expenditure, deferred stripping, royalties and lease payments and is used by management to evaluate performance inclusive of sustaining expenditure required to maintain current production levels.

C3² total cost is defined as AISC² less sustaining capital expenditure, deferred stripping and general and administrative expenses net of insurance, plus depreciation and exploration. This metric is used by management to evaluate the operating performance inclusive of costs not classified as sustaining in nature such as exploration and depreciation.

Often, but not always, forward-looking statements or information can be identified by the use of words such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate" or "believes" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved.

With respect to forward-looking statements and information contained herein, the Company has made numerous assumptions including among other things, assumptions about continuing production at all operating facilities, the price of copper, gold, nickel, silver, iron, cobalt, pyrite, zinc and sulphuric acid, anticipated costs and expenditures, the success of Company's actions and plans to reduce greenhouse gas emissions and carbon intensity of its operations and the ability to achieve the Company's goals. Forward-looking statements and information by their nature are based on assumptions and involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward looking statements or information. These factors include, but are not limited to, future production volumes and costs, the temporary or permanent closure of uneconomic operations, costs for inputs such as oil, power and sulphur, political stability in Panama, Zambia, Peru, Mauritania, Finland, Spain, Turkey, Argentina and Australia, adverse weather conditions in Panama, Zambia, Finland, Spain, Turkey, Mauritania, and Australia, labour disruptions, potential social and environmental challenges (including the impact of climate change), power supply, mechanical failures, water supply, procurement and delivery of parts and supplies to the operations, the production of off-spec material and events generally impacting global economic, political and social stability. For mineral resource and mineral reserve figures appearing or referred to herein, varying cut-off grades have been used depending on the mine, method of extraction and type of ore contained in the orebody.

See the Company's Annual Information Form for additional information on risks, uncertainties and other factors relating to the forward-looking statements and information. Although the Company has attempted to identify factors that would cause actual actions, events or results to differ materially from those disclosed in the forward-looking statements or information, there may be other factors that cause actual results, performances, achievements or events not as anticipated, estimated or intended. Also, many of these factors are beyond First Quantum's control. Accordingly, readers should not place undue reliance on forward-looking statements or information. The Company undertakes no obligation to reissue or update forward-looking statements or information as a result of new information or events after the date hereof except as may be required by law. All forward-looking statements made and information contained herein are qualified by this cautionary statement.
