FIRST QUANTUM MINERALS REPORTS FOURTH QUARTER

AND YEAR-END 2022 RESULTS

(In United States dollars, except where noted otherwise)

Toronto, Ontario (February 14, 2023) - First Quantum Minerals Ltd. (“First Quantum” or “the Company”) (TSX: FM)

today reports results for the three months ended December 31, 2022 (“Q4 2022”) of net earnings attributable to

shareholders of the Company of $117 million ($0.17 earnings per share) and adjusted earnings1 of $151 million ($0.22

adjusted earnings per share 2). For the year -ended 2022, the Company reported net earnings attributable to

shareholders of the Company of $1,034 million ($1.50 per share) and adjusted earnings1 of $1,064 million ($1.54 per

share1).

“2022 can be summarized as a challenging year for First Quantum and the mining industry as a whole. The year was

characterized by volatile commodity prices and rising costs and interest rates, creating a challenging macroeconomic

environment. We remain focused on driving consistent operational performance, successful execution of our

brownfield projects and discipline with our ca pital investments. Debt reduction continues to be a priority,”

commented Tristan Pascall, Chief Executive Officer. “I am grateful for the dedication of the entire team at First

Quantum. It is with these efforts that First Quantum was able to navigate through the challenges in 2022.”

Q4 2022 SUMMARY

In Q4 2022, First Quantum reported gross profit of $361 million, EBITDA 1 of $647 million, net earnings attributable

to shareholders of $0.17 per share, and adjusted earnings of $0.22 per share 2. Relative to the t hird quarter (“Q3

2022”), fourth quarter financial results benefitted from higher realized metal prices3, partially offset by lower gold

sales volumes.

Total copper production for the fourth quarter was 206,007 tonnes, a 6% increase from Q3 2022. The quar ter-over-

quarter increase in production was attributable to Kansanshi and Sentinel, with grades improving at both operations.

Production at Kansanshi showed improvement following an enhanced water management strategy and access to

higher grade ore.

Copper C1 cash cost2 of $1.86 per lb for Q4 2022 was $0.04 per lb higher than Q3 2022. The increase in costs were

primarily related to higher maintenance activities and lower by-product credits. During the fourth quarter of 2022,

input prices and operational costs have broadly stabilized, albeit at elevated levels, following inflationary pressures

throughout the first three quarters of the year. There is a lag before such market changes flow through to unit costs.

Three-year guidance on production, C1 cash costs2, all-in sustaining cost (“AISC”)1 and capital expenditures that was

previously disclosed on January 16, 2023 remains unchanged. For 2023, copper production is forecast to be 770,000

to 840,000 tonnes while copper C1 cash costs1 are guided to be $1.65 to $1.85 per lb. Capital cost guidance for 2023

is $1,600 million.

1 EBITDA and adjusted earnings are non-GAAP financial measures. These measures do not have a standardized meaning prescribed by IFRS and might not be comparable to similar

financial measures di sclosed by other issuers. Adjusted earnings and EBITDA were previously named comparative earnings and comparative EBITDA, res pectively, and the

composition remains the same. See “Regulatory Disclosures”.

2 Adjusted earnings per share, copper C1 cash cost (copper C1), and all-in sustaining cost (AISC) 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”.

Q4 2022 OPERATIONAL HIGHLIGHTS

Total copper production for Q4 2022 was 206,007 tonnes, up from the 194,974 tonnes reported in Q3 2022, as

Kansanshi and Sentinel reported higher production and Cobre Panamá continued to achieve strong quarterly

production. Copper sales volumes in Q4 2022 totaled 198,912 tonnes, approximately 7,000 tonnes lower than

production during the quarter due to timing of shipments.

Copper C1 cash cost 1 averaged $1.86 per lb in Q4 2022, up from $1.82 per lb in Q3 2022. Copper C1 cash cost 1 at

Kansanshi and Sentinel improved relative to Q3 2022 due to higher copper production.

 Cobre Panamá produced 89,652 tonnes of copper in Q4 2022, a 2% decrease over production levels in the

previous quarter due to lower throughput as grades and recoveries remained consistent with Q3 2022 levels.

During the quarter, 21.9 million tonnes of ore was processed, including a record volume of 8.3 million tonnes

in December. Copper C1 cash cost1 of $1.63 per lb was $0.20 per lb higher than the previous quarter due to

higher labour costs and e xposure to spot electricity prices in Q4 2022. Unit 2 of the power plant at Cobre

Panamá had a scheduled biennial maintenance shutdown in October, with replacement electrical power

sourced from the national grid at spot prices. A collar structure for coal purchases is currently in place with

the ceiling price already exercised from July 2021 onwards, thereby limiting exposure to further increases in

the coal price until the end of 2023.

 Kansanshi’s copper production of 34,802 tonnes in Q4 2022 was 4,940 to nnes higher than the previous

quarter on grade improvement. Feed grades to all three circuits increased from the third quarter mainly due

to deployment changes made during the second half of the year. This resulted in an enhanced water

management strategy in M12, which led to a more consistent feed grade to the mixed and oxide circuits.

Deployment changes in M17 also resulted in de -risking the plan by balancing the mixed ore feed between

strata and ore associated with narrow-veins, which had a positive impact on feed grade consistency. Sulphide

feed grades improved as mining took place in areas with mainly strata mineralization. Work is continuing on

reconciliations and the learnings are incorporated in the near -term mine plans to further improve and

optimize sequences. Copper C1 cash cost1 of $2.81 per lb was $0.12 lower than Q3 2022 mainly due to higher

production volumes from improved grades.

 Sentinel reported copper production of 73,409 tonnes in Q4 2022, 9,289 tonnes higher than the previous

quarter as grade, in particular, and throughput improved in the fourth quarter, despite experiencing heavy

rainfall in December. The operation achieved record quarterly throughput benefitting from the treatment of

soft, well-fragmented ore and the performance of the f ourth in-pit crusher. Copper C1 cash cost 1 of $1.55

per lb was $0.22 per lb lower than the preceding quarter reflecting improved production volumes.

 Ravensthorpe payable nickel production of 4,450 tonnes was 510 tonnes lower than the third quarter.

Beneficiation and HPAL availability remained stable, however, there was a planned autoclave descale

shutdown in October. Nickel C1 cash cost1 was $9.32 per lb, a $0.20 per lb increase over the previous quarter.

While fuel, labour, and sulphur prices declined in the fourth quarter, higher nickel C1 cash cost1 resulted from

lower production levels and lower payabilities.

FINANCIAL HIGHLIGHTS

 Gross profit of $361 million and EBITDA 1 of $647 million for the fourth quarter were 20% and 11% higher,

respectively, than Q3 2022 with the increase mainly attributable to improved metal prices.

 Cash flows from operating2 activities of $237 million ($0.34 per share) for the quarter were $288 million lower

than Q3 2022 mainly due to working capital movements related to trade and other receivables.

 Net debt1 increased by $363 million during the quarter, taking the net debt 1 balance to $5,692 million as at

December 31, 2022. As at December 31, 2022, total debt was $7,380 million (September 30, 2022, total debt

was $7,118 million). The increase in net debt and total debt is mainly attributable to working capital

movements and $195 million dividend paid to non-controlling interests. The Company continues to target a

further $1 billion reduction in debt in the medium term.

 The Company announced that it intends issue a notice of partial redemption on February 15, 2023 for $450

million of its outstanding 6.5% Senior Notes due March 2024 to be redeemed on February 25, 2023.

 On February 14, 2023, the Company declared a final dividend of CDN$0.13 per share, in respect of the

financial year ended December 31, 2022. The final dividend together with the interim dividend of CDN$0.16

per share declared on July 26, 2022 amount to a total of CDN$0.29 per share for the 2022 financial year. The

dividend will be paid on May 8, 2023 to shareholders of record on April 17, 2023.

BROWNFIELD PROJECTS

The CP100 Expansion project at Cobre Panamá is in early operation with the new process water circuits and bypass

feeders in use, with the balance of the expansion scope in ore commissioning with ore having been introduced to

both Ball Mill 6 and the primary screening facility. Ramp up of production is in progress to achieve a throughput rate

of 100 Mtpa by the end of 2023.

At the S3 Expansion, detail design is progressing well and incorporates enhancements and efficiencies introduced by

the latest generation of preferred equipment and the learnings of the Sentinel and Cobre Panamá operations. Long-

lead mining fleet and long -lead process plant equipment have been ordered with deliveries commencing in the

second half of 2023. Overall project procurement is ap proximately 25% committed. Across the three -year guidance

period provided on January 16, 2023, project capital expenditures for the S3 Expansion project is expected to be

approximately $900 million, with the majority of the spend to occur over 2023 and 202 4. Total capital expenditure

for the S3 Expansion project remains unchanged at $1.25 billion.

Enterprise remains on schedule for first ore in the first half of 2023. In parallel, mine facilities are being developed,

including the satellite administration o ffice, workshop, fuel storage, haul road upgrade, dewatering boreholes and

other facilities. Plant refurbishment, completion and commissioning activities remain on schedule.

COBRE PANAMÁ UPDATE

The Company and the Government of Panamá (“GOP”) have been in discussions surrounding a refreshed concession

contract for the Cobre Panamá mine (see the Management’s Discussion and Analysis for the three months and year-

ended December 31, 2022 for additional disclosure). In July 2021, the current GOP, established a multidisciplinary

commission including the Minister of Commerce and Industrie s (“MICI”), Minister of Environment, and Minister of

Employment to seek resolution on a refreshed contract.

On December 21, 2022, Minera Panamá, S.A. (“MPSA”) received formal notification from MICI of a resolution requiring

MPSA to submit a plan within 10 working days to suspend commercial operations at Cobre Panamá and put the

mine under “care and maintenance.” As required by the GOP, MPSA is working on a plan for how to operate Cobre

Panamá under care and maintenance. At the same time, the Company is pursuing every available legal recourse to

avoid this outcome. Due to the legal processes and the GOP’s role in responding to the plan, the timing and impact

of this requirement remain uncertain.

On January 26, 2023, the Panamá Maritime Authority (“AMP”) issued a resolution that required the suspension of

concentrate loading operations at the Cobre Panamá port, Punta Rincón (the “Port”), until evidence was provided

that the process of certification of the calibration of the scales by an accredited company had been initiated. MPSA

filed legal proceedings to challenge the resolution, staying its legal effects. Nevertheless, the Company submitted

the required proof of the initiation of the certificatio n process on February 2, 2023, and, on February 7, 2023, the

Company submitted certifications of the calibration of the scales and weights. AMP rejected the certification on

February 8, 2023, claiming that the certification company is not accredited in Pan amá, even though the provider

MPSA used is on the list of accredited companies published by MICI. MPSA is challenging this decision and, at the

same time, is working to find another accredited certification company that the GOP will accept. In the meantime ,

the AMP has maintained its order suspending loading operations at the Port. In addition, since at least January 24,

2023, the AMP has issued individual letters to the Company’s maritime pilot service providers instructing them not

to provide services to incoming vessels for loading copper concentrate at the Port.

MPSA is pursuing all available avenues to restart shipments at the Port , including all legal recourse available ,

engagement with other accredited and accreditable expert companies and continuous communications with the pilot

services suppliers. As previously reported, if AMP’s measures persist, it may become necessary to shut down the

Cobre Panamá mine if concentrate is not shipped by approximately February 20, 2023 due to limited storage capacity

on site.

The Company has indicated to the GOP that it is prepared to accept and pay a minimum of $375 million per year to

the GOP, comprised of corporate taxes and a profit -based mineral royalty of 12 to 16 percent, with downside

protections. The parties continue to finalize the details behind these principles, including the appropriate mechanisms

that would achieve the desired outcome. This includes the stability of the tax and royalty regime and reasonable

protections against early termination.

The Company continues to engage in good faith discussions with the GOP and remains ready to reach an agreement

that is fair and equitable to both parties. Once an agreement is concluded and the full contract is documented, it is

expected that the newly drafted legislation would be put to the Panamanian National Assembly for approval.

NULLITY ACTIONS BY THIRD PARTIES

In December 2016, the Concession Contract held by MPSA was extended for a second 20 -year term (from March 1,

2017). In 2018, two third parties filed ac tions in the Supreme Court seeking a declaration that the extension was

illegal and therefore, null and void (the “Nullity Actions”).

The Company refutes the claims made in the Nullity Actions and has been advised by external counsel that the

extension process followed by the MICI in 2016 was correct. In connection with those proceedings, the Procurador

de la Administración (“Administration’s Attorney”) issued formal opinions in 2018 and 2019 stating that the Extension

Resolution was legal. However, during January 2023, the Administration’s Attorney changed the previous position

taken and filed motions in both Nullity Actions asking that the Extension resolution be deemed without legal effect.

MPSA has filed an opposition against the Administration’s Attorney’s motions. The Supreme Court has not yet ruled

on the matter.

ARBITRATION PROCEEDINGS

MPSA has initiated arbitration processes under the existing Concession Contract and the Canada-Panamá Free Trade

Agreement. Both of these processes are under way and in the initial stages.

ZAMBIAN POWER SUPPLY

Water levels at the Kariba Dam reached a record low at the end of 2022. In January 2023, ZESCO requested that the

Company’s Zambian operations reduce its power usage for a two -week period due to the lower water l evels at the

Kariba Dam and planned maintenance at the 300 megawatt Maamba power plant. During the period, Kansanshi and

Sentinel conducted planned maintenance that was previously scheduled for February and March. Although the

country is experiencing load -shedding, there is no major impact on the Zambian mining operations. Heavier than

normal rains have been experienced in the current rainy season which sho uld replenish the Kariba basin from April

2023 onwards.

ZAMBIAN TAX REGIME

On September 30, 2022, the Minister of Finance and National Planning presented the 2023 National Budget. The key

enacted changes affecting the mining industry include the restructuring of the Mineral Royalty Tax Regime and the

reinstatement of taxes and import duty on fuel.

The restructuring of the Mineral Royalty tax was enacted on January 1, 2023 and includes an amendment to the

calculation of mineral royalty tax to be on an incremental basis. In addition, an amendment to the mineral royalty tax

bands determining the mineral royalty tax rate applicable at various price levels were made, as shown below.

The reinstatement of taxes and duties on fuel, which were suspended in January 2021, includes the reinstatement of

excise duties and standard-rated VAT became effective from October 1, 2022. In addition, effective January 1, 2023,

import duties on fuel (previously at a rate of 25%) were reinstated with a corresponding red uction in the rate of the

import duties from 25% to ‘free’, resulting in nil impact of the reinstatement of these duties.

KANSANSHI – CONVERSION OF ZCCM DIVIDEND RIGHTS TO ROYALTY RIGHTS

During the fourth quarter of 2022, an agreement was entered into betw een the Company’s subsidiary Kansanshi

Mining Plc (“KMP”) and its partner ZCCM Investments Holdings Plc (“ZCCM-IH“) to convert ZCCM-IH’s dividend rights

in KMP into royalty rights . A dividend of $195 million was paid to ZCCM -IH on the signing of this agree ment. Post

completion, this transaction also provides for 20% of the KMP VAT refunds as at June 30, 2022 to be paid to ZCCM -

IH, as and when these are received by KMP from the Zambian Revenue Authority (“ZRA”). Completion of this

transaction is expected during the first half of 2023.

2023 to 2025 GUIDANCE UPDATE

Three-year guidance on production, C1 cash costs1, AISC1 and capital expenditures that was previously disclosed on

January 16, 2023 remains unchanged. For 2023, copper production is forecast to be 770,000 to 840,000 tonnes while

copper C1 cash costs1 are guided to be $1.65 to $1.85 per lb. Capital cost guidance for 2023 is $1,600 million.

Cobre Panamá is expected to produce 350,000 to 380,000 tonnes of copper and 140,000 to 160,000 ounces of gold

in 2023. Production for 2023 includes commissioning of the CP100 Expansion in the first quarter of 2023 with a ramp-

up over the course of the year to achieve an annualized throughput rate of 100 Mtpa by the end of 2023. For 2023

as a whole, grades and recoveries are expected to be consistent with 2022 levels but will fluctuate from quarter to

quarter. At this time, the timing and impact of any care and maintenance regime enacted by the MICI or any shutdown

following receipt of the Resolution issued by the AMP remain uncertain. Given this, production and unit cost guidance

for Cobre Panamá is based on normal operations with no disruption to production.

At Kansanshi, production in 2023 is expected to range from 130,000 to 150,000 tonnes of copper and 95,0 00 to

105,000 ounces of gold. Copper production in 2023 and 2024 reflects similar levels as 2022 with lower oxide grades

and sulphide grades while mining vein -hoisted areas. Copper and gold production in 2025 includes some limited

production associated with the S3 Expansion, expected to commence in the second half of 2025.

At Sentinel, copper production in 2023 is expected to be between 260,000 and 280,000 tonnes. The operation has

experienced particularly heavy rains in January, which has impacted mining operations and the sequence of mining.
