First Quantum Minerals Reports Third Quarter 2024 Results

TORONTO, Oct. 22, 2024 - First Quantum Minerals Ltd. ("First Quantum" or the "Company") (TSX: FM) today reports results for the three months ended September 30, 2024 ("Q3 2024" or the "third quarter") of net earnings attributable to shareholders of the Company of $108 million ($0.13 earnings per share) and adjusted earnings¹ of $119 million ($0.14 adjusted earnings per share²).

"While it is pleasing to see continued strong operational performance from the Zambian operations during the third quarter, this was marred by a tragic accident in September resulting in the death of a colleague at Kansanshi. We continue to support the family and we remain committed to ensure the safety of our colleagues across the business. While ZESCO power restrictions continue, our Zambian team's proactive actions have resulted in minimal production impacts. The S3 Expansion continues to make good progress for production in the second half of 2025," commented Tristan Pascall, Chief Executive Officer of First Quantum. "In Panama, we continue to engage with local authorities for the approval of the Preservation and Safe Management program for Cobre Panamá. With Cobre Panamá remaining in a state of preservation and safe management and the ongoing capital expenditures related to the S3 Expansion, we are continuing efforts to maintain the strength of the balance sheet and, as such, additional hedges were added during the quarter."

Q3 2024 SUMMARY

In Q3 2024, First Quantum reported gross profit of $456 million, EBITDA¹ of $520 million, net earnings attributable to shareholders of $0.13 per share, and adjusted earnings per share² of $0.14. Relative to the second quarter of 2024 ("Q2 2024"), third quarter financial results improved due to higher copper and gold sales volumes along with stronger realized gold prices. Total copper production for the third quarter was 116,088 tonnes, a 13% increase from Q2 2024. Copper C1 cash cost³ was $1.57 per lb in the third quarter, a decrease of 9% quarter-over-quarter.

There were a number of developments during the third quarter that are also detailed in this news release:

• 2024 Guidance for copper production has narrowed to the top end of previous guidance, while gold production guidance has increased. Copper C1 cash cost³ guidance has narrowed to the low end of previous guidance.
• During the quarter, the Company entered into additional derivative contracts. More than half of planned production and sales remains exposed to spot copper prices through the period until the end of 2025.
• On October 15, 2024, FQM Trident signed a $425 million unsecured term loan facility with a maturity date of September 2028 to replace the previous Trident facility that was scheduled to mature in December 2025.
• While Zambia's energy crisis persisted in the third quarter, operational adjustments minimized the effect on copper production. Minimal operational interruptions are expected heading into the fourth quarter of 2024.
• As part of the ongoing board renewal program, the Company is pleased to announce the appointments of Ms. Juanita Montalvo and Mr. Hanjun ("Kevin") Xia to its Board of Directors with immediate effect.

Q3 2024 OPERATIONAL HIGHLIGHTS

Total copper production for the third quarter was 116,088 tonnes, a 13% increase from Q2 2024 as a result of higher production at the Zambian operations. While Zambia's energy crisis persisted in the third quarter, First Quantum's proactive sourcing of supplementary power minimized disruptions, allowing normal operations to continue for most of the quarter. The impact of higher costs associated with the imported power was mitigated by strong gold by-product credits during the quarter. Copper C1 cash cost¹ was $0.16 per lb lower quarter-over-quarter at $1.57 per lb, reflecting higher copper production, along with lower fuel costs. Copper sales volumes totalled 112,094 tonnes, approximately 3,994 tonnes lower than production due to the timing of shipments.

• Kansanshi reported the highest quarterly copper production since the fourth quarter of 2021. Copper production of 49,810 tonnes in Q3 2024 was 8,303 tonnes higher than the previous quarter as continued mining discipline resulted in higher feed grades on the mixed and oxide circuits. During the quarter, the sulphide and mixed mills were swapped to increase the throughput of mixed material which contained higher grades. Gold production of 31,659 ounces for the third quarter of 2024 was the highest quarterly production since the first quarter of 2022. Copper C1 cash cost¹ of $1.29 per lb was $0.22 lower quarter-over-quarter due to improved production volumes. Production guidance for 2024 has increased to 155,000 - 165,000 tonnes of copper from 130,000 - 150,000 tonnes while gold production guidance has increased to 90,000 - 100,000 ounces from 65,000 - 75,000 ounces. A swap of the mixed and sulphide mills will continue in the fourth quarter in order to maximize mixed grade through the mills. Fourth quarter gold production is expected to be lower than the third quarter due to lower grades.
• Sentinel reported copper production of 58,412 tonnes in Q3 2024, approximately 4,817 tonnes higher than the previous quarter as improved throughput levels benefitted from better performance of the in-pit crushers as well as improved fragmentation of the ore. Copper C1 cash cost¹ of $1.86 per lb was lower than the preceding quarter as a result of higher production volumes. Copper production guidance for 2024 has narrowed to 220,000 - 230,000 tonnes from 220,000 - 250,000 tonnes. Mining performance and throughput is expected to further improve over the remainder of the year with the ongoing development of Stage 3 (Western Cut-back) which will enable improved mining productivities due to the increased availability of softer material on shorter haul cycles. The improvement in fragmentation experienced in the third quarter that led to improved crushing and milling rates is expected to continue for the remainder of the year. The development of the Stage 1 sump is on schedule to be completed during October 2024 along with other site works in preparation for the upcoming wet season.
• Enterprise had its first full quarter of commercial production, producing 4,827 tonnes of nickel during the third quarter, a decrease from 6,147 tonnes in Q2 2024. The plant has been stable and achieved record throughput in August 2024. The plant was shut down for the last nine days of September due to power supply restrictions in order to prioritize power for the copper circuit. Plant operations resumed in October. Production guidance for 2024 for Enterprise remains unchanged at 17,000 - 20,000 contained tonnes of nickel. Good progress has been made in preparation for the wet season and securing of the south wall. The focus for the remainder of the year will be on increasing mobile equipment reliability through supporting the contractor uplift maintenance practices in order to increase mining volumes.
• Cobre Panamá remains in a phase of preservation and safe management ("P&SM") with production halted and production guidance suspended. During the quarter, the process plant assets inspection frequency was changed from 28 to 56 days, while the equipment start-up frequency remains unchanged at 14 days to ensure equipment preservation through dynamic lubrication and monitoring asset conditions. All the major ultra-class mobile equipment is in a maintenance cycle that adheres to the original equipment manufacturer's long-term storage recommendations and includes periodic inspections as well as scheduled startups. In addition to asset preservation, a key focus continues to be on maintaining the environmental stability for all areas of the site and compliance with the environmental and social impact study for the project, which remains in force. The costs for the P&SM program in the third quarter were approximately $13 million per month, which included labour, maintenance spares, contractor's services, electricity, and other general expenses. During the quarter, activities on site were further curtailed with reduction in active equipment for the tailings management facility and open pit maintenance. For the remainder of the year, P&SM expenses are expected to be $11 - $13 million per month, depending on the level of environmental stability and asset integrity programs. The Company is actively managing the P&SM costs of Cobre Panamá and will adjust the level of employment and cost of these activities according to the conditions on the ground in Panama. Approximately 121 thousand dry metric tonnes of copper concentrate remain onsite.

HEDGING PROGRAM

During the quarter, and consistent with the approach outlined in the second quarter results of 2024, the Company entered into derivative contracts, in the form of additional unmargined zero cost copper collars, as protection from downside price movements, financed by selling price upside beyond certain levels on a matched portion of production. More than half of planned production and sales remains exposed to spot copper prices through the period until the end of 2025.

At October 22, 2024, the Company had zero cost copper collar contracts for 245,400 tonnes at weighted average prices of $4.18 per lb to $5.01 per lb outstanding with maturities to December 2025.

FQM TRIDENT FACILITY

At Trident, on October 15, 2024, FQM Trident signed a $425 million unsecured term loan facility (the "FQM Trident Facility") with a maturity date of September 2028 to replace the previous Trident facility that was scheduled to mature in December 2025. Repayments on the FQM Trident Facility will commence in March 2026 and are due every six months thereafter. This action is in line with the Company's prudent management of its debt maturities.

CONSOLIDATED FINANCIAL HIGHLIGHTS

2024 GUIDANCE

Guidance is based on a number of assumptions and estimates as of September 30, 2024, including among other things, assumptions about metal prices and anticipated costs and expenditures. Guidance involves estimates of known and unknown risks, uncertainties and other factors, which may cause the actual results to be materially different.

Guidance has been updated to reflect performance year-to-date and the outlook for the remainder of the year. Copper production guidance has narrowed to a range of 400,000 - 420,000 tonnes from 370,000 - 420,000 tonnes. Strong performance from Kansanshi, Guelb Moghrein and Cayeli has resulted in an increase in copper production guidance for these operations. Sentinel guidance range has been narrowed with the upper end reduced based on performance to date. Gold production guidance has increased to 120,000 - 135,000 ounces from 95,000 - 115,000 ounces to reflect higher grades experienced to date at Kansanshi. Nickel production guidance remains unchanged.

Copper unit cost guidance has been narrowed for both C1¹ and AISC¹ to reflect performance to date, coupled with a favourable Zambian kwacha/US dollar exchange rate and strong by-product credits, partially offset by increased Zambian electricity costs. Guidance does not include any P&SM costs with respect to Cobre Panamá. C1 cash costs¹ guidance assumes a gold price of $2,500 per ounce for the remainder of the year, an average Brent crude oil price of $85 per barrel and a Zambian kwacha/US dollar exchange rate of 25.

Previous nickel unit cash cost guidance for 2024 was for Ravensthorpe only and was withdrawn in the second quarter. There is no guidance provided for Enterprise as operations ramp up this year. Care and maintenance costs for Ravensthorpe are expected to be approximately $2 million per month in the fourth quarter.

Guidance for total capital expenditure remains unchanged at $1,250 - $1,400 million.

ZAMBIA POWER UPDATE

During the quarter, Zambia's energy crisis persisted due to the El Niño-induced drought, which has significantly reduced the country's hydropower generation. Despite these challenges, First Quantum's proactive sourcing of supplementary power minimized disruptions, allowing normal operations to continue for most of the quarter.

In late September 2024, planned maintenance work on a 150 MW thermal generation unit at Maamba Collieries led to a nine-day, 30% power reduction imposed on Zambian Electricity Supply Corporation Limited ("ZESCO")-supplied power to the Company's Zambian mine sites. However, the Company's supplementary sourcing strategy limited the actual impact on its Zambian mine sites to a 10% reduction in maximum power availability during the 9-day period. Operational adjustments, including rescheduling maintenance and prioritizing critical activities, minimized the effect on copper production.

By the end of the quarter, with the restoration of 150 MW from the thermal generation unit and increased ZESCO imports from South Africa, power availability at the Company's Zambian mine sites returned to normal and minimal operational interruptions are expected heading into the fourth quarter of 2024.

The annualized impact of $0.06 per lb on Copper C1 cash costs¹ from the supplementary sourcing strategy is aligned with estimates communicated in the second quarter of 2024 and expected to remain unchanged for the balance of the financial year.

ZAMBIA 2025 NATIONAL BUDGET

The 2025 National Budget was presented on September 27, 2024 by the Minister of Finance and National Planning, Dr. Situmbeko Musokotwane, under the theme "Building Resilience for Inclusive Growth and Improved Livelihoods".

No significant changes were announced to the mining tax regime, with the Minister reaffirming his commitment to maintaining stable and predictable tax policies to encourage investment.

COBRE PANAMÁ UPDATE

At the request of the Ministry of Commerce and Industries ("MICI"), Cobre Panamá delivered a draft plan for the first phase of the P&SM plan on January 16, 2024. The incoming administration reviewed the P&SM plan upon taking office in July 2024 and requested additional information, which was submitted by the Company on August 27, 2024, along with a formal presentation to MICI on September 25, 2024. The plan is still pending government approval and, therefore, not all aspects of the plan have been implemented by the Company.

During the quarter, President Mulino made public statements to the effect that his government intends to address the Cobre Panamá mine in early 2025. The Government of Panama ("GOP") also announced that an integrated audit of Cobre Panamá would be conducted with international experts to establish a factual basis to aid in decision making for the future of the mine. The Company welcomes this audit process, although the timeline remains unclear.

In parallel with the P&SM of the site, the Company has also embarked on a comprehensive program of public outreach in order to make more transparent information available to the public about Cobre Panamá. Since the beginning of 2024, these efforts have reached over 20,000 Panamanian citizens through site visits (which are currently suspended, pending P&SM approval) and briefings in universities, schools, and public spaces. A further 40,000 Panamanians have undertaken an online virtual tour of the mine.

Steps towards two arbitration proceedings have been taken by the Company, one under the Canada-Panama Free Trade Agreement ("FTA") and the other under the International Chamber of Commerce ("ICC") pursuant to the arbitration clause of the Refreshed Concession Contract.

• ICC Arbitration: On November 29, 2023, Minera Panamá S.A. ("MPSA") initiated arbitration before the ICC's International Court of Arbitration pursuant to the ICC's Rules of Arbitration and Clause 46 of the Refreshed Concession Contract to protect its rights under Panamanian law and the Refreshed Concession Contract that the GOP agreed to in October 2023. The arbitration clause of the contract provides for arbitration in Miami, Florida. A final hearing for this matter is scheduled for September 2025.
• FTA Arbitration: On November 14, 2023, First Quantum submitted a notice of intent to the GOP initiating the consultation period required under the FTA. First Quantum submitted an updated notice of intent on February 7, 2024. First Quantum is entitled to seek any and all relief appropriate in arbitration, including, but not limited to, damages and reparation for Panama's breaches of the Canada-Panama FTA. These breaches include, among other things, the GOP's failure to permit MPSA to lawfully operate the Cobre Panamá mine prior to the Supreme Court's November 2023 decision and the GOP's pronouncements and actions concerning closure plans and P&SM at Cobre Panamá. The Company has the right to file its arbitration claim under the FTA within three years of Panama's breaches of the FTA.

The Company reiterates that arbitration is not the preferred outcome for the situation in Panama and it remains committed to dialogue with the GOP and to being part of a solution for the country and its people.

KANSANSHI S3 EXPANSION

During the third quarter of 2024, assembly of the SAG and ball mills at the S3 Expansion at Kansanshi was completed and installation of the gearless mill drives commenced. Work in priority areas, including the primary crusher, continued as per schedule and focus now shifts to piping and electrical work. Commissioning activities have started in the 33kv distribution substation and is expected to be energized in the fourth quarter. System configuration of the plant control system has been completed for the primary circuit and is now focused on ancillary systems and services.

REGULATORY DISCLOSURES

Non-GAAP and Other Financial Measures

EBITDA, ADJUSTED EARNINGS (LOSS) AND ADJUSTED EARNINGS (LOSS) PER SHARE

EBITDA, adjusted earnings (loss) and adjusted earnings (loss) per share 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.

¹ The three and nine months ended September 30, 2024 include an impairment charge of $2 million and $71 million respectively, following the decision to scale back operations at Ravensthorpe in Q1 and subsequently placing the mine on care and maintenance in May.
² The three months ended September 30, 2023, following a corporate reorganization within the Kansanshi segment, included a restructuring expense of $31 million.

REALIZED METAL PRICES

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 SHARE

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 DEBT

Net debt is comprised of bank overdrafts and total debt less unrestricted cash and cash equivalents.

CASH COST, ALL-IN SUSTAINING COST, TOTAL COST

The consolidated cash cost (C1), all-in sustaining cost (AISC) and total cost (C3) 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 cost, AISC and C3, 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.

AISC is defined as cash cost (C1) 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.

C3 total cost is defined as AISC 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.
