First Quantum Minerals Reports Second Quarter 2024 Results

(In United States dollars, except where noted otherwise)

TORONTO, July 23, 2024 (GLOBE NEWSWIRE) -- First Quantum Minerals Ltd. (“First Quantum” or the "Company”) (TSX: FM) today reports results for the three months ended June 30, 2024 (“Q2 2024” or the "second quarter") of a net loss attributable to shareholders of the Company of $46 million ($0.06 loss per share) and an adjusted loss¹ of $13 million ($0.02 adjusted loss per share²).

“We had another solid quarter in Zambia and with the work achieved to date, both Kansanshi and Sentinel are set up well for the remainder of the year. At Enterprise, the continued successful commissioning and ramp up has enabled the declaration of commercial production on June 1, 2024 while the S3 Expansion is progressing well and on track for completion in mid-2025. We also initiated a copper hedge program as we continue efforts to maintain the strength of the balance sheet,” commented Tristan Pascall, Chief Executive Officer of First Quantum. “Finally, it was pleasing to reach a Shareholder Rights Agreement with Jiangxi Copper, which formalizes a clear basis for the relationship between us. The relationship with Jiangxi Copper, who have been a long standing customer, has solidified since their purchase of First Quantum shares in 2019. We look forward to Jiangxi Copper's continued strong support on the strategic direction of the Company.”

Q2 2024 SUMMARY

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

• A Shareholder Rights Agreement with Jiangxi Copper Company Limited (“Jiangxi Copper”);
  
  
  
  
• Additional power supply restrictions by the Zambian Electricity Supply Corporation Limited ("ZESCO");
  
  
  
  
• Implementation of a copper hedging program;
  
  
  
  
• Updated NI 43-101 Technical Report for Kansanshi

In Q2 2024, First Quantum reported gross profit of $333 million, EBITDA¹ of $336 million, a net loss attributable to shareholders of $0.06 per share, and an adjusted loss per share² of $0.02. Relative to the first quarter of 2024 (“Q1 2024”), second quarter financial results improved due to higher copper and gold prices.

Total copper production for the second quarter was 102,709 tonnes, a 2% increase from Q1 2024 as a result of higher production at Kansanshi. Copper sales volumes totaled 94,628 tonnes, lagging production due to the timing of shipments and vessel delays. Copper C1 cash cost³ was $1.73 per lb in the second quarter, benefiting from strong by-product gold credits. Enterprise declared commercial production as of June 1, 2024.

2024 guidance remains unchanged for copper and gold production, while nickel production has narrowed to reflect year-to-date production at Ravensthorpe. Copper unit cost guidance remains unchanged.

SHAREHOLDERS RIGHTS AGREEMENT

On July 23, 2024, the Company entered into a shareholder rights agreement (the “Shareholder Rights Agreement” or “SRA”) with Jiangxi Copper. The Shareholder Rights Agreement will formalize and provide structure to the relationship that exists between the two organizations. Further, the Shareholder Rights Agreement is also expected to support reasonable sharing of best practices between the parties across the copper value chain, including in smelting and refining, in which Jiangxi Copper is a world leader. The four key provisions of the SRA are:

1. Nomination rights: Jiangxi Copper will have the right to nominate one person for consideration by the Nominating and Governance Committee of the board of the Company, which will make a recommendation to the board regarding the appointment or election of the nominee;
   
   
   
   
2. Standstill: Jiangxi Copper has agreed to customary standstill restrictions which, subject to certain exceptions, prohibit Jiangxi Copper from taking certain actions, including, without the consent of the Company, acquiring shares of the Company during the term of the SRA and for a period of six months following the termination of the SRA;
   
   
   
   
3. Restrictions on dispositions: Jiangxi Copper has agreed to certain restrictions on the disposition of its shares of the Company which include, subject to certain exceptions (i) the right of the Company to designate one or more purchasers of such shares in the event that Jiangxi Copper proposes to sell a block of 5% or more of the shares of the Company, and (ii) not selling such shares to any person that owns, or would own, following completion of such sale, more than 9.9% of the issued and outstanding shares of the Company (allowing for certain ordinary secondary market transactions executed through the TSX or other stock exchanges on which the common shares are listed); and,
   
   
   
   
4. Shareholder support: Jiangxi Copper has agreed that it will not withhold its vote in respect of the director nominees proposed by management of the Company or the reappointment of auditors, nor will it vote against any other matters recommended by the Company’s board of directors (other than matters relating to an acquisition of all the shares of the Company by a third party, a sale of a controlling interest in any material asset of the Company or an issuance of shares that would result in a person owning more than 10% of the issued and outstanding shares of the Company).
   
   

The SRA will terminate upon the earlier of July 23, 2027 and the date on which Jiangxi Copper’s ownership percentage of the Company’s shares falls below 10%. Jiangxi Copper and the Company may terminate the SRA at any time by mutual written agreement.

ZAMBIA POWER UPDATE

On June 11, 2024, ZESCO informed the mining sector that power curtailment for all mining customers will increase from the 20% previously communicated to 40% effective July 1, 2024. In response, First Quantum has strategically decided to source additional power beyond the formal requirements set by ZESCO to ensure stable operations and support the grid during this challenging situation. Effective July 1, 2024, the Company is sourcing 193 MW, or 52% of its maximum power requirement, from regional sources. Consequently, the impact on C1 copper cash costs¹ is expected to be $0.06 per lb, up from the $0.03 per lb communicated in the first quarter of 2024. The Company anticipates it will be able to sufficiently substitute curtailed power with imports from the region for the duration of the emergency and thereby avoid operational interruptions.

The energy generation deficit is anticipated to ease with Zambia’s next rainy season, which, according to traditional weather patterns, begins in mid-November and lasts until April. Typically, there is a 3 to 4 month delay before the rains impact Zambia's hydro-power generation, such that by early 2025, Zambia's hydro generation capabilities should begin to recover.

In the medium term, the Company is in advanced discussions with three Independent Power Producers to provide partial offtake commitments for advanced projects scheduled to come online in the first and second quarter of 2025. The commercial operation date of these advanced projects align well with the commissioning and ramp-up of the S3 Expansion project at Kansanshi.

Longer term, the Company is advancing offtake arrangements with independent renewable power producers. This includes a large scale solar/wind generation project with commissioning targeted for 2026/2027, and hydro projects in Zambia's Northwest and Northern Provinces. Additionally, the Company is following developments related to infrastructure investments to build transmission lines with Angola and Tanzania, countries with current and forecast excess power.

COBRE PANAMÁ UPDATE

On July 1, 2024, the new president of Panama, José Raúl Mulino, was inaugurated into office. In his inauguration speech, President Mulino announced that the Government of Panama ("GOP") will conduct, with international experts, a strict environmental audit of the Cobre Panamá mine. The Company reiterates that transparency and compliance with environmental standards have always been fundamental for the development of its operations and welcomes the audit process to broaden the understanding of conditions at the mine and the challenges to environmental management brought about by the abrupt mine suspension.

Steps towards two arbitration proceedings have been taken by the Company, one under the Canada-Panama Free Trade Agreement (“FTA”), and another 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 Preservation and Safe Management ("P&SM") at Cobre Panamá. The Company has the right to file its arbitration claim under 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 new government of Panama and to being part of a solution for the country and its people.

KANSANSHI S3 EXPANSION

During the second quarter of 2024, construction of the S3 Expansion project at Kansanshi continued to focus on major mechanical equipment assembly and installation, namely the mills and primary crusher, in parallel with assembly and installation of structural steel, pipe work and electrical work. Long lead equipment is being received on site and the last delivery of flotation cells was completed early in the third quarter of 2024. System configuration of the plant control system has commenced with a focus on early commissioning of medium voltage power reticulation and plant services in the milling area. The majority of the capital spend on the S3 Expansion is expected to occur in 2024, with first production expected in mid-2025.

KANSANSHI NI 43-101 TECHNICAL REPORT

On July 23, 2024, the Company filed an updated NI 43-101 Technical Report for Kansanshi. The Kansanshi Technical Report discloses an updated Mineral Resource estimate which accounts for mining and processing depletions since the filing of a previous report in September 2020. The updated Measured and Indicated Mineral Resource estimate, as at the end of December 2023, now stands at 1,160.9 Mt at an average copper grade of 0.61%TCu (excluding stockpiles). Commensurate with the increase in the Mineral Resource inventory, and also accounting for depletion, the end of December 2023 reported Proven and Probable Mineral Reserve has now risen to 935.2 Mt with an average grade of 0.56%TCu, and with an additional 169.5 Mt stockpiled at an average grade of 0.40%TCu. The increase in Mineral Reserve extends the operating life of Kansanshi by 5 years to 2049.

Q2 2024 OPERATIONAL HIGHLIGHTS

Total copper production for the second quarter was 102,709 tonnes, a 2% increase from Q1 2024. Copper sales volumes totaled 94,628 tonnes, approximately 8,081 tonnes lower than production due to the timing of shipments and vessel delays at Walvis Bay, Namibia and Dar-es-Salaam, Tanzania related to weather, port congestion and schedule disruptions. Copper C1 cash cost¹ was $0.29 per lb lower quarter-over-quarter at $1.73 per lb, benefiting from strong gold by-product credits.

• Kansanshi’s copper production of 41,507 tonnes in Q2 2024 was 10,034 tonnes higher than the previous quarter as a result of higher feed grades on the sulphide and mixed circuits. Grades improved due to higher-grade material from the Main 15 and Main 17 cutbacks, predominately from mining at higher elevation. Copper C1 cash cost¹ of $1.51 per lb was $0.83 lower quarter-over-quarter due to higher by- product credits as a result of improved gold production and stronger gold prices. Production guidance for 2024 is maintained at 130,000 to 150,000 tonnes of copper and 65,000 to 75,000 ounces of gold. Copper grades are expected to modestly improve over the course of the year as mining progresses at higher elevation areas with higher-grade material from the Main 15 and Main 17 cutbacks. A swap of the mixed and sulphide mills is planned for the third quarter of 2024 in order to maximize mixed grade through the mills during this period.
  
  
  
  
• Sentinel reported copper production of 53,595 tonnes in Q2 2024, approximately 8,630 tonnes lower than the previous quarter. The decline in production was due to lower grades in the second quarter, which was expected given the exceptionally strong grades in Q1 2024. The ongoing Stage 3 (Western Cut-back) development progressed well during the second quarter with the in-pit crusher successfully commissioned ahead of schedule and below budget and enabled access to softer ore. Copper C1 cash cost¹ of $1.94 per lb is higher than the preceding quarter, reflecting lower production volumes. Copper production guidance for 2024 is maintained at 220,000 to 250,000 tonnes. Mining performance and throughput is expected to continue to improve over the remainder of the year with the ongoing development of Stage 3, which will enable improved mining productivities and increased availability of softer material on shorter haul cycles.
  
  
  
  
• Enterprise produced 6,147 tonnes of nickel during the second quarter, an increase from 4,031 tonnes in Q1 2024. The first half of the year has yielded consistently positive results, meeting expectations and supporting the recommendation to declare commercial production as of June 1, 2024. Mining volumes are steadily improving and ramping up in accordance with the mobilization strategy and enhanced contractor fleet asset management. The plant performance has been strong, with increased fresh feed leading to higher recovery rates and a focus on optimising recovery for each ore type. An increase in mining volumes is anticipated through the dry season with a focus on the South Wall cutback and sinking the pit sump in preparation for the wet season. Ore variability controls will be prioritized as mixed oxides with lower feed grade will be primarily processed in September and October of 2024, but nickel production consistency is expected to be maintained through higher throughput at full plant capacity and stable milling rates. Production guidance for 2024 has been narrowed to 17,000 to 20,000 contained tonnes of nickel (previously 10,000 to 20,000 tonnes).
  
  
  
  
• Cobre Panamá currently remains in a phase of P&SM with production halted and production guidance suspended. During the second quarter, the process plant preservation and maintenance cycle was changed from 14 to 28 days, with equipment being run and monitored. This new maintenance cycle allows for the completion of outstanding work and corrective maintenance activities required to maintain the integrity of the assets. Furthermore, 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. This equipment will be required as part of the P&SM plan that is awaiting approval by the Ministry of Commerce and Industries. The costs for the P&SM program in the second quarter were approximately $17 million per month. For the remainder of the year, P&SM expenses are expected to be $15 to $20 million per month, depending on the level of environmental stability and asset integrity programs. Approximately 121 thousand dry metric tonnes of copper concentrate remains onsite. The sale of this concentrate will result in a net cash inflow of approximately $265 million at current market prices. Relevant ministries and government agencies (a cross-government committee) conducted an inspection at site. In the report of this committee, it was recommended that the copper concentrate be exported and the power plant be re-started.
  
  
  
  
• At Ravensthorpe, nickel production for the second quarter totaled 1,253 contained tonnes of nickel, compared to 3,740 tonnes in Q1 2024. Ravensthorpe was placed into care and maintenance from May 2024. Preparation and cleaning of plant and equipment for care and maintenance that commenced in May 2024 will be finalized in the first few weeks of the third quarter of 2024. Activity will be focused on execution of preventative maintenance plans that have been developed with equipment being run and monitored to help maintain it in good working condition. In addition, the Company continues to support its personnel and local regional communities through the change in circumstances at Ravensthorpe. Care and maintenance costs for Ravensthorpe are expected to be approximately $5 million per month for the third quarter and reduce to approximately $2 million per month from the fourth quarter onwards. Production guidance has been lowered to 5,000 contained tonnes of nickel (previously 12,000 to 17,000 tonnes) to reflect the closure.

FINANCIAL HIGHLIGHTS

Financial results continue to be impacted by Cobre Panamá being in a phase of P&SM, however, the second quarter benefitted from strong copper and gold prices.

• Gross profit for the second quarter of $333 million was $177 million higher than Q1 2024, while EBITDA¹ of
  
  $336 million for the same period was $156 million higher.
  
  
  
  
• Cash flows from operating activities of $397 million ($0.48 per share²) for the quarter were $12 million lower than Q1 2024.
  
  
  
  
• Net debt³ increased by $160 million during the quarter, attributable mainly to planned higher capital expenditures at Kansanshi, bringing the net debt³ level to $5,437 million, with total debt at $6,313 million, as at June 30, 2024.

HEDGING PROGRAM

During the second quarter, the Company entered into derivative contracts, in the form of 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 remains exposed to spot copper prices through the period until end-2025.

At July 23, 2024, the Company had zero cost copper collar contracts for 269,650 tonnes at weighted average prices of $4.24 per lb to $5.00 per lb outstanding with maturities to December 2025.

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 months ended June 30, 2023, include an impairment charge of $60 million 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 June 30, 2023, include royalty attributable due to ZCCM-IH of $18 million relating to the year ended December 31, 2022.

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.
