   TORONTO, Oct.  28, 2025  (GLOBE NEWSWIRE) -- First  Quantum Minerals Ltd. (“First Quantum” or the "Company”) (TSX: FM) today  reports results for the three and nine months ended September 30, 2025  (“Q3 2025” or the "third quarter") of net loss attributable to  shareholders of the Company of $48 million ($0.06 loss per share) and  adjusted loss1 of $16 million ($0.02 adjusted loss per share2) for the third quarter.
    “During  the quarter, we made meaningful progress on our priorities for 2025. We  continued to proactively strengthen our balance sheet and manage our  liquidity with the agreement of a $1 billion non-debt gold stream  arrangement with Royal Gold. In addition, we undertook a series of bond  transactions to extend our debt profile, with our earliest bond maturity  now occurring in 2029. Operationally, production continued to improve  quarter-over-quarter and we remain on track with our production guidance  for the year. We have successfully delivered the Kansanshi S3 Expansion  project, which produced first concentrate in August. This marks First  Quantum’s ninth major self-built project in the last two decades that  has allowed the Company to grow into the leading global copper producer  that it is today,” said Tristan Pascall, Chief Executive Officer of  First Quantum. “In Panama, the remaining concentrate shipments were  completed safely and without incident during the quarter. The Government  of Panama is advancing the environmental study. We continue our work on  Preservation and Safe Management of Cobre Panamá and expect to restart  the power plant in the fourth quarter. Our focus remains on reaching a  constructive resolution for the mine that serves the best interests of  our stakeholders, the government, and the people of Panama.”
    Q3 2025 SUMMARY
    In Q3 2025, First Quantum reported gross profit of $360 million, EBITDA1 of $435 million, net loss attributable to shareholders of $0.06 per share, and adjusted loss per share1  of $0.02. Relative to the second quarter of 2025 (“Q2 2025”), while  third quarter financial results benefitted from improved production at  Kansanshi and Sentinel, stronger realized metal prices2,  and concentrate sales from Cobre Panamá, financial results were  impacted by lower sales at Kansanshi related to the replenishment of  inventories.
    Along with third quarter results, the Company has updated 2025 guidance:
    - Copper production guidance has narrowed from 380,000 – 440,000 tonnes to 390,000 – 410,000 tonnes,
 - Gold production guidance has narrowed from 135,000 – 155,000 tonnes to 140,000 – 150,000 ounces,
 - Nickel production guidance has narrowed from 15,000 – 25,000 tonnes to 18,000 – 23,000 tonnes,
 - Copper C1 cash cost3 has narrowed from $1.85 – $2.10 per lb to $1.95 – $2.10 per lb,
 - Nickel C1 cash cost3  has been lowered from $5.00 – $6.50 per lb to $4.75 – $5.50 per lb, and
 - Total  capital expenditure guidance has been reduced from a range of $1,300 –  $1,450 million to $1,150 – $1,250 million, based on spend to date and  the latest expected timing of capital expenditures.
    Q3 2025 OPERATIONAL HIGHLIGHTS
    Total  copper production for the third quarter was 104,626 tonnes, a 15%  increase from Q2 2025 as a result of higher production from Sentinel and  Kansanshi. Copper C1 cash cost4 was $0.05 per lb lower  quarter-over-quarter at $1.95 per lb, reflecting higher copper  production volumes. Copper sales volumes totalled 118,825 tonnes,  approximately 14,199 tonnes higher than production due to the shipment  of 24,306 tonnes of copper from Cobre Panamá during the quarter with the  approval of the Preservation and Safe Management ("P&SM") plan by  the Government of Panama ("GOP"). Copper sales volumes at Kansanshi were  lower than production as anode inventory levels were replenished  following the planned 40-day smelter shutdown in the second quarter,  which returned to operation in early July.
    - Kansanshi  reported copper production of 46,881 tonnes in Q3 2025, an increase of  6,778 tonnes from the previous quarter due to an increase in mill  throughput as the Kansanshi S3 Expansion project was commissioned and  produced first concentrate in August. The accelerated ramp-up of S3,  circuit stabilization and recoveries surpassed budgeted expectations and  had a positive impact on production, contributing 6,136 tonnes of  copper during the quarter. Copper C1 cash cost4 of $1.34 per  lb was $0.13 lower quarter-over-quarter as a result of higher  production. Copper production guidance for 2025 has narrowed to 175,000 –  185,000 tonnes, while gold production guidance has increased to 110,000  – 115,000 ounces. Copper and gold production in the fourth quarter are  expected to exceed third quarter levels, driven by a faster than  anticipated ramp up of the Kansanshi S3 Expansion throughput and  recoveries, resulting in stable circuit performance ahead of schedule.
 - Sentinel  reported copper production of 51,336 tonnes in Q3 2025, 8,228 tonnes  higher than the previous quarter. Mill throughput averaged over 5  million tonnes per month, representing a 14% increase from Q2 2025  levels, benefitting from improved ore fragmentation, reliability and  performance of the primary crushers and performance of the crushed ore  mill feed stockpile. Copper C1 cash cost1 of $2.53 per lb was  $0.24 lower than the preceding quarter as a result of higher production  volumes. During the quarter, the Company continued to advance its  maintenance program to address the fatigue in the Ball Mill 2 flange  bolts. Building on the progress made in the previous quarter, work is  ongoing in collaboration with the original equipment manufacturer  ("OEM") and specialist engineering consultants to address the high  levels of ongoing routine maintenance otherwise required to counter the  fatigue situation. The development of a long-term corrective procedure  remains a key focus to ensure sustained mill performance and  reliability. The relocation of In-Pit Crusher 2 has been completed and  is expected to be commissioned in the fourth quarter of 2025. The  innovative low-energy consumption rail run conveyor, which was showcased  on the Company's Zambia tour in September, will require some  modification as performance testing continues towards final  commissioning of the asset. Production guidance for 2025 has been  updated to 190,000 – 200,000 tonnes of copper to reflect performance to  date. Grades are expected to be relatively higher in the fourth quarter  of 2025 as mining progresses to the bottom of the Stage 1 pit for sump  development ahead of the wet season and the transition to higher primary  sulphide ore volumes reporting from Stage 3.
 - In  the third quarter of 2025, Enterprise produced 5,767 tonnes of nickel, a  44% increase over the previous quarter due to higher throughput and  supported by 19% higher recoveries quarter-over-quarter. Grades  continued to be impacted by a higher proportion of transitional ore from  the Stage 3 area. Nickel C1 cash cost1 of $4.17 per lb is  $1.66 lower than the previous quarter due to higher production volumes.  Production guidance for 2025 was narrowed to 18,000 – 23,000 contained  tonnes of nickel while nickel unit cost guidance has been reduced to  reflect year-to-date operational performance.
 - At  Cobre Panamá, maintenance refurbishment of subsystems in the flotation  area and conveyor belts began last quarter and continues as part of the  overall fixed plant preservation plan. Special attention has been given  to valve inspections and maintenance throughout the plant, along with a  more thorough examination of the stockpile feeders, which were found to  be in fair condition. Detailed inspections with OEM specialists began  last quarter to assess the condition of the mobile fleet after 18 months  of long-term preservation storage. Inspections of ultra-class haul  trucks and production drills are approaching completion and rope shovels  are scheduled for review in the upcoming quarter. Findings are being  used to refine the preservation strategy to ensure asset safety and  integrity. P&SM costs during the third quarter averaged  approximately $15 million per month and included services related to the  copper concentrate shipments. P&SM costs are expected to increase  to approximately $15 million to $17 million per month with the restart  of the power plant in the fourth quarter of 2025, although the  incremental costs are anticipated to be partially offset by the  potential sale of excess power to support the national grid. Royalty  payments associated with the copper concentrate sales are paid in  arrears and expected to be made during the fourth quarter of 2025.
    2025 GUIDANCE 
    Guidance  provided below is based on a number of assumptions and estimates as of  September 30, 2025, 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 for copper, gold and nickel production to reflect  year-to-date performance and outlook for the remainder of the year.
    Copper  production guidance has narrowed from 380,000 – 440,000 tonnes to  390,000 – 410,000 tonnes. Strong performance from Kansanshi has resulted  in guidance being narrowed to the upper end of the original guidance  range while guidance for Guelb Moghrein and Çayeli has increased.  Guidance for Sentinel has been updated to reflect the performance to  date.
    Gold production guidance has been narrowed  towards the upper end of the range to reflect higher grades experienced  to date at Kansanshi.
    Copper unit cost guidance has narrowed for both C15 and AISC2  to reflect performance to date, coupled with strong by-product credits  and lower fuel costs, offset by higher employee costs and increased  Zambian electricity costs. The assumptions underlying this guidance  include a gold price of $3,800 per ounce, an average Brent crude oil  price of $75 per barrel, a Zambian kwacha to US dollar exchange rate of  26, and royalties based on consensus copper prices.
    Nickel unit cost guidance for Enterprise nickel has been reduced to reflect year-to-date operational performance.
    Guidance  for total capital expenditure has been reduced from a range of $1,300 –  $1,450 million to $1,150 – $1,250 million, based on spending to date  and the latest expected timing of capital expenditures.
    Capital  expenditure for the three and nine months ended September 30, 2025 was  $280 million and $833 million, respectively. Year-to-date expenditure on  the Kansanshi S3 Expansion project was approximately $233 million, with  a total of $1,080 million spent since the start of the project and  approximately a further $32 million committed. The project is expected  to finish under the original budget of $1,250 million. Ongoing project  capital works on Tailings Storage Facility 2 ("TSF2") are expected to  complete in the second quarter of 2026.
    Interest  expense on debt for the full year 2025 is expected to be approximately  $550 million to $575 million, reflecting the financing activities that  have taken place throughout the year, and excludes interest accrued on  related party loans to Cobre Panamá and Ravensthorpe, finance cost  accreted on deferred revenue, capitalized interest expense and accretion  on asset retirement obligation.
    Cash outflow on  interest paid is expected to be approximately $450 million to $475  million for the full year 2025. This excludes interest paid on related  party loans to Cobre Panamá and Ravensthorpe as well as capitalized  interest paid.
    Capitalized interest is expected to be approximately $75 million for the full year 2025.
    The effective tax rate is expected to be approximately 30% to 35% for the full year 2025.
    The  full year 2025 depreciation expense excluding Cobre Panamá is expected  to be between $675 million to $725 million. While under P&SM,  depreciation at Cobre Panamá is expected to be $80 million to $100  million on an annualized basis, which includes approximately $40 million  of depreciation associated with the sale of copper concentrate from the  shed.

    FINANCIAL HIGHLIGHTS
    Financial results continue to be impacted by the suspension of Cobre Panamá.
    - Gross profit for the third quarter of $360 million was $9 million higher than Q2 2025, while EBITDA6  of $435 million for the same period was $35 million higher, benefitting  from higher copper sales volumes from the sale of 24,306 tonnes of  copper in concentrate from Cobre Panamá and higher realized copper, gold  and nickel prices2.
 - Cash flows from operating activities of $1,195 million ($1.44 per share7)  for the quarter were $415 million higher than Q2 2025 primarily due to  the receipt of $1,000 million under the gold streaming agreement with  Royal Gold.
 - Net debt8  decreased by $702 million during the quarter to $4,751 million with  total debt at $5,711 million as at September 30, 2025. The decrease in  net debt2 is attributable to the receipt of $1,000 million under the gold stream agreement and EBITDA1  contributions of $435 million, offset by capital expenditures of $280  million, interest paid of $166 million, inclusive of $25 million of  capitalized interest, and $136 million of working capital outflows.

    GOLD STREAMING AGREEMENT
    The  Company, through a wholly-owned subsidiary incorporated in Canada,  entered into a gold streaming agreement with RGLD Gold AG, a wholly  owned subsidiary of Royal Gold, Inc. in August 2025. The Company  received a $1,000 million upfront cash payment in exchange for gold  deliveries referenced to copper production from the Kansanshi mine. The  transaction provides long-term, unsecured, non-debt capital which  significantly enhances liquidity. The Company maintains full exposure to  the copper production and the majority of the gold production at  Kansanshi while retaining full exposure to the recently identified  near-surface gold zone occurrences. For more information on the  transaction, please refer to the August 5, 2025 news release "First  Quantum Announces $1.0 Billion Gold Stream" on the Company's website.
    SENIOR NOTES TRANSACTIONS
    During  the quarter, the Company executed a series of Senior Notes transactions  that successfully extended its debt maturity profile to 2029.
    - On  August 6, 2025, the Company announced the tender offer to purchase for  cash any and all of the Company’s outstanding 6.875% Senior Notes due  2027.
 - On August  6, 2025, the Company announced the tender offer to purchase for up to  $250 million aggregate principal amount outstanding of its 9.375% Senior  Notes due 2029.
 - An  offering of $1,000 million 7.250% Senior Notes due 2034 was completed  on August 20, 2025. Gross proceeds from the notes offering, together  with cash on the balance sheet, was used to fund the tender offer for  the existing 6.875% Senior Notes due 2027 and to redeem any Senior Notes  due 2027 not accepted for purchase in the tender offer, to fund the  tender offer for a portion of the existing 9.375% senior secured second  lien notes due 2029 and pay related fees, costs and expenses.
     HEDGING PROGRAM
    As  at October 28, 2025, the Company had zero cost copper collar contracts  outstanding for 171,300 tonnes at weighted average prices of $4.12 per  lb to $4.72 per lb with maturities to June 2026. Of these, there were  72,825 tonnes with maturities to the end of 2025 with weighted average  prices of $4.11 per lb to $4.85 per lb. Approximately 70% of remaining  planned production and sales in 2025, and approximately 50% of planned  production and sales for the first half of 2026 are protected from spot  copper price movements. The increase in hedged proportion of the  remaining 2025 production is largely as a result of narrowed production  guidance. In addition, as at October 28, 2025, the Company had zero cost  gold collar contracts outstanding for 63,768 ounces at weighted average  prices of $2,954 per oz to $4,215 per oz with maturities to June 2026.

   1 EBITDA  and adjusted earnings (loss) are non-GAAP financial measures, and net  debt is a supplementary financial measure. These measures do not have a  standardized meaning under IFRS and might not be comparable to similar  financial measures disclosed by other issuers. Adjusted earnings (loss)  have been adjusted to exclude items from the corresponding IFRS measure,  net earnings (loss) attributable to shareholders of the Company, which  are not considered by management to be reflective of underlying  performance. The Company has disclosed these measures to assist with the  understanding of results and to provide further financial information  about the results to investors and may not be comparable to similar  financial measures disclosed by other issuers. The use of adjusted  earnings (loss) and EBITDA represents the Company’s adjusted earnings  (loss) metrics. See “Regulatory Disclosures”.  2  Adjustments to EBITDA in 2025 relate principally to the adjustment for  expected phasing of Zambian VAT and the tax effect on unrealized  movements in the fair value of derivatives designated as hedging  instruments (2024 - relate to an impairment expense of $71 million, a  foreign exchange revaluations gain of $14m and a restructuring expense  of $12 million). 3 Adjusted earnings (loss) per  share, realized metal prices, copper all-in sustaining cost (copper  AISC), copper C1 cash cost (copper C1) and total cost of copper (copper  C3) are non-GAAP ratios, which do not have a standardized meaning  prescribed by IFRS and might not be comparable to similar financial  measures disclosed by other issuers. See “Regulatory Disclosures”. 4 Excludes  the sale of copper anode produced from third-party concentrate  purchased at Kansanshi. Sales of copper anode attributable to  third-party concentrate purchases were 1,844 tonnes and 8,609 tonnes for  the three and nine months ended September 30, 2025 (7,537 tonnes and  25,427 tonnes for the three and nine months ended September 30, 2024).
    COBRE PANAMÁ UPDATE
    On May 30, 2025, the GOP approved and formally instructed the execution of the P&SM plan.
    The  P&SM approval authorized the export of 122,520 dry metric tonnes of  copper concentrate. Following the first shipment at the end of the  second quarter, the remaining concentrate was exported during the third  quarter of 2025. The proceeds from the concentrate sales will be used to  fund P&SM activities, including local supply and procurement in  Panama and the ongoing environmental stewardship of the mine and its  surroundings.
    The execution of the P&SM plan  also provides for the import of fuel and the restart of Cobre Panamá’s  power plant. The Company has commenced pre-commissioning activities of  the power plant and the mobilization of specialists to site. The power  plant is currently anticipated to restart in the fourth quarter of 2025,  with the first 150MW unit expected to be fired and synchronized with  the grid in November. With the re-commissioning of the power plant,  approximately 100 new employment hires have been made.
    In  August, the Ministry of Environment ("MiAmbiente") issued the final  Terms of Reference for an integral audit of the Cobre Panamá mine. On  October 10, MiAmbiente formally issued the order for SGS Panama Control  Services Inc. (“SGS”) to proceed with the integral audit. MiAmbiente and  the Ministry of Commerce and Industries, together with SGS, are  coordinating the audit planning and implementation, which is expected to  cover environmental, social, legal, and fiscal compliance aspects.
    In  addition to the integral audit, the authorities have continued with the  statutory 6-monthly audits of Cobre Panama’s compliance with its  commitments under the ESIA. The most recently published audit achieved  100% compliance on environmental topics, with one overall  non-conformance related to occupational health and safety commitments.  The 11th external audit field inspection component was completed in June  2025 and the final report is scheduled for submission in the fourth  quarter.
    Engagement with local governments in  nearby municipalities was further strengthened during the quarter.  Coordination efforts focused on aligning community initiatives in  education, health, infrastructure, and environmental programs to deliver  tangible benefits for more than 3,500 children across over 40 schools  and over 5,000 community members, while also reinforcing relationships  and transparency in the implementation of the P&SM plan. Public  outreach efforts also continued nationwide, including informational  sessions and online engagement. Since 2024, more than 170,000  Panamanians have been reached directly through over 1,000 public events,  while over 325,000 Panamanians have participated in the Company’s  virtual mine tour platform.
    KANSANSHI S3 EXPANSION
    The  Kansanshi S3 Expansion project successfully transitioned from  commissioning into early operation, with first ore introduced in July  and first concentrate produced in August. The project remains on  schedule, with operational ramp-up now in progress, and expected to  finish under the original budget of $1,250 million. The plant is now  maintaining 24 hour operations with support from the commissioning team  and vendor specialists. The Kansanshi S3 Expansion contributed 6,136  tonnes of copper in the third quarter.
    The  project achieved 98% construction completion and 95% of systems have  been handed over to commissioning/operations. During the quarter, the  full copper circuit was brought online in stages with a focus on tuning  the circuit and ramping up towards nameplate and steady state  production. Final outstanding construction and commissioning is in  progress for the gravity gold circuit, non-process infrastructure and  assisting with any changes associated with the operational ramp up.
    In  addition, the smelter expansion works are complete whilst acid plant 5  is currently in the hot commissioning stage. Ongoing project capital  works on TSF2 are expected to complete in the second quarter of 2026.  Mining operations at the South East Dome pit have progressed, with  approximately 240,000 tonnes of ore fed to the S3 plant year-to-date.
    Zambian Power Supply
    During  the third quarter of 2025, Zambia’s national power supply remained  stable, supported by improved hydrology and ongoing regional imports,  even as supply generation in the country remains below national  electricity demand levels. Although reservoir levels at Lake Kariba  recovered during the first half of the year, the force majeure declared  in early 2024 remains in effect. The Company experienced no material  load shedding during the period, however, the Company anticipates  maintaining supplementary sourcing and import arrangements through to  the first half of 2027 to support the continued recovery of Lake  Kariba’s hydropower capacity.
    The annualized impact of the Company’s supplementary sourcing strategy on 2025 copper C1 cash cost9  is expected to rise modestly from the previously reported $0.07 per lb  to approximately $0.11 per lb, reflecting continued and expanded  supplementary sourcing from higher-cost emergency imports and domestic  thermal generation.
    __________ 1  C1 cash cost (C1) is a non-GAAP ratio, and does not have a standardized  meaning prescribed by IFRS and might not be comparable to similar  financial measures disclosed by other issuers. See “Regulatory  Disclosures”
    KANSANSHI EXPLORATION UPDATE
    During  the third quarter, the Company continued the program to evaluate the  new near-surface gold zone occurrences in the South East Dome area at  Kansanshi. The Company is currently mobilizing leaching test equipment  to the site to assist with its understanding of in-situ grade estimation  and possible recoveries, alongside the pilot plant which was operating  during the third quarter. Exploration is ongoing with the intent of  defining a resource for the near-surface gold zone occurrences.
    ÇAYELI EXPLORATION UPDATE
    On  October 28, 2025, the Company filed an updated NI 43-101 Technical  Report on Reserves and Resources for Çayeli. The report discloses an  updated Mineral Resource estimate, which accounts for mining and  processing depletions within the Main Orebody, and discloses a maiden  mineral resource estimate for a newly defined copper and zinc deposit  named the South Orebody approximately 300 metres from the Main Orebody.  The updated and combined Indicated Mineral Resource, as at April 30,  2025, is 9.33 million tonnes (“Mt”) at average grades of 1.46% Cu, 2.54%  Zn and 10.37 ppm Ag. Commensurate with the Mineral Resource update, and  also accounting for Main Orebody depletions, the reported Probable  Mineral Reserve is 7.31 Mt at average grades of 1.51% Cu, 2.34% Zn and  10.31 ppm Ag. The increase in Mineral Reserve extends the operating life  of Çayeli to 2036. The updated NI 43-101 Technical Report is available  on the Company’s public filings on SEDAR+ at www.sedarplus.com.
    ENVIRONMENT, SOCIAL AND GOVERNANCE 
    THINK! Safety Program at Çayeli: Çayeli  has reached a notable milestone of more than three years without a  lost-time injury, reflecting the site’s strong safety culture and  ongoing commitment of all employees to maintaining a safe workplace.  This achievement highlights the success of the Company’s THINK! Safety  Program, which forms the foundation of First Quantum’s health and safety  strategy. Supported by strong leadership, the program drives employee  engagement and field leadership through interactive toolbox talks,  visible management participation, and a strong feedback culture. The  THINK! Safety program has delivered measurable outcomes, including  significant reductions in total recordable injuries and high-potential  incidents, and over 1,100 employee safety suggestions actioned,  underscoring its continued effectiveness and impact at Çayeli.
    Repurposing industrial land for green energy at Pyhäsalmi: In  Finland, First Quantum inaugurated the country’s first solar park in a  mining area, located at the Pyhäsalmi mine. The 13 MWp Callio Solar  Park, built on a filled tailings pond, demonstrates innovative land  repurposing by converting former industrial land into renewable energy  production. The project features 22,800 panels with an estimated annual  output of 10 GWh and will be complemented by a 7.5 MWh battery storage  facility. Connected through the mine’s existing power grid and  substation, the solar park supplies energy to ongoing site operations  with surplus power fed into the national grid. This milestone, delivered  in collaboration with the Town of Pyhäjärvi and the municipal owned  development company Callio Pyhäjärvi, highlights First Quantum’s  commitment to sustainable mine closure practices, local economic  resilience, and the transition to renewable energy.

   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.

    With  respect to forward-looking statements and information contained herein,  the Company has made numerous assumptions including among other things,  assumptions about the geopolitical, economic, permitting and legal  climate in which the Company operates; continuing production at all  operating facilities (other than Cobre Panamá and Ravensthorpe); the  price of certain precious and base metals, including copper, gold,  nickel, silver, cobalt, pyrite and zinc; exchange rates; anticipated  costs and expenditures; the Company’s ability to continue to source  sufficient power at its Zambian operations to avoid interruption  resulting from the country’s decreased power availability; mineral  reserve and mineral resource estimates; the timing and sufficiency of  deliveries required for the Company’s development and expansion plans;  the ability of the Company to reduce greenhouse gas emissions at its  operations; future exploration results; and the ability to achieve the  Company’s goals, including with respect to the Company’s climate and  sustainability initiatives. 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,  Türkiye, Argentina and Australia, adverse weather conditions in Panama,  Zambia, Finland, Türkiye, Mauritania, and Australia, 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 and events generally  impacting global economic, political and social stability and  legislative and regulatory reform.

    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.
