FIRST QUANTUM MINERALS REPORTS FIRST QUARTER 2025 RESULTS

(In United States dollars, except where noted otherwise)

Toronto, Ontario (April 23, 2025) - First Quantum Minerals Ltd. (“First Quantum” or the "Company ”) (TSX: FM)

today reports results for the three months ended March 31, 2025 (“Q1 2025” or the "first quarter") of net loss

attributable to shareholders of the Company of $23 million ($0.03 loss per share) and adjusted earnings1 of $2 million

($0.00 adjusted earnings per share2).

“Kansanshi and Sentinel held up well in the first quarter and we remain on track for meaningful production growth

over the remainder of the year, driven by the S3 Expansion project at Kansanshi. I ’m please d to report that

construction is progressing steadily and remains on schedule. In Panama, following the suspension of arbitration,

we reaffirm our commitment to constructive engagement with the government and people of Panama to reach a

resolution for the Cobre Panamá mine,” said Tristan Pascall, Chief Executive Officer of First Quantum. “ Amid rising

concerns about global growth due to uncertainty around trade and tariff policy, we continue with initiatives to

strengthen our balance sheet and enhance our fi nancial flexibility. Our copper hedges provide important protection

and our gold production provides as a natural hedge during this period of volatility. We further enhanced our near -

term liquidity position by $750 million through the recent notes offering and, following quarter-end, entering into an

additional prepayment agreement. These initiatives represent meaningful progress in strengthening our financial

flexibility and we remain focused on further initiatives to support the balance sheet. ”

Q1 2025 SUMMARY

In Q1 2025, First Quantum reported gross profit of $331 million, EBITDA1 of $377 million, net loss attributable to

shareholders of $0.03 per share, and adjusted earnings per share 2 of $0.00. Relative to the fourth quarter of 2024

(“Q4 2024”), first quarter financial results were weaker due to lower sales volumes for copper, gold and nickel. Total

copper production for the first quarter was 99,703 tonnes, an 11% decrease from Q4 2024. Copper C1 cash cost 3

was $1.95 per lb in the first quarter, an increase of 16% over the previous quarter.

Along with the financial and operating results for the first quarter, the following are also detailed in this news release:

• Cobre Panamá Update: Following engagement with the Government of Panama’ s ("GOP") legal counsel, the

Company has agreed to discontinue the International Chamber of Commerce (“ICC”) arbitration proceedings and

to suspend the Canada- Panama Free Trade Agreement (“FTA”) arbitration. The Company is awaiting official

communication regarding next steps with respect to the power plant and copper concentrate at site.

• Kansanshi S3 Expansion Update: Construction remains on schedule for mid-2025 completion with production

expected in the second half of 2025. During the quarter, the project achieved 83% construction completion and

has handed 20% of systems over to commissioning.

• Zambia Power Update: First Quantum has maintained and extended supplementary power arrangements with

regional third-party energy traders. As the Kansanshi S3 Expansion ramps up in the second half of 2025, the

Company anticipates sourcing up to 60% of its electricity from imports.

• Board Update: As part of Board renewal program, Peter Buzzi and Ambassador Brian Nic hols have been

nominated to be appointed as Directors at the 2025 Annual General Meeting ("AGM") on May 8, 2025. Andrew

Adams and Joanne Warner will retire at the conclusion of the AGM. As previously announced, Robert Harding

will retire at the conclusion of the 2025 AGM and Kevin McArthur will succeed as Chair.

• Hedging program: During the quarter, the Company continued to enter into derivative contracts. Approximately

half of planned production and sales in 2025 and approximately 40% of planned production and sales for the first

half of 2026 are protected from spot copper price movements.

• Copper Prepayment Transaction: On April 23, 2025, on the basis of the previously -agreed commercial terms,

the Company has supplemented the sale of copper to Jiangxi Copper Company in return for an additional $500

million prepayment.

Q1 2025 OPERATIONAL HIGHLIGHTS

Total copper production for the first quarter was 99,703 tonnes, an 11% decrease from Q4 2024 mainly as a result

of lower production at Sentinel. Kansanshi and Sentinel encountered the seasonal impacts from the rains in Zambia,

however, dewatering and pumping solutions all coped adequately. Copper C1 cash cost 1 was $0.27 per lb higher

quarter-over-quarter at $1.95 per lb, reflecting lower copper production volumes and higher Zambian employee and

maintenance costs, which were partially offset by strong gold by -product credits. Copper sales volumes totalled

101,960 tonnes, approximately 2,257 tonnes higher than production.

• Kansanshi reported copper production of 46,544 tonnes in Q1 2025, a decrease of 1,595 tonnes from the

previous quarter due to lower feed grades as the swap of the mixed and sulphide mills that allowed for higher

grades in the fourth quarter returned to normal at the end of last year. Gold production continued to be strong

at 29,868 ounces in the first quarter. Copper C1 cash cost 1 of $1.34 per lb was $0.13 higher quarter -over-

quarter as a result lower production along with higher smelter costs. Production guidance for 2025 remains

unchanged at 160,000 to 190,000 tonnes of copper and 100,000 to 110,000 ounces of gold. A six -week

maintenance shutdown of the Kansanshi smelter is planned in the second quarter of 2025. Copper and gold

production in 2025 includes production associated with the Kansanshi S3 Expansion, with first production

expected in the second half of 2025. The majority of the initial feed for S3 will be sourced from low -grade

stockpiles.

• Sentinel reported copper production of 46,361 tonnes in Q1 2025, 10,199 tonnes lower than the previous

quarter due to lower throughput and the mining of lower grades from Stage 3. Copper C1 cash cost1 of $2.55

per lb was $0.44 higher than the preceding quarter as a result of lower production volumes. The Company

has also begun a maintenance program to address early indicators of fatigue in the Sentinel mills, a

development consistent with mills of similar age and design from the same manufacturer. The program will

be conducted with the original equipment manufacturer and specialist engineering consultants in a manner

that minimizes production disruptions. 2025 copper production guidance remains unchanged at 200,000 to

230,000 tonnes. A 4-day full maintenance shutdown of the Sentinel plant is planned in the second quarter

of 2025, followed by tailings thickener upgrades in the second half of 2025. The focus at Sentinel will continue

to be on increasing mill throughput with various ongoing initiatives to optimize blast fragmentation,

maintaining full stockpiles, improving milling rates, increasing tailings thickener throughput rates and flotation

recovery. Grades are expected to be lower than 2024, but expected to be relatively higher in the second half

of 2025 as mining progresses to the bottom of the Stage 1 pit for sump development ahead of the wet

season. Stage 3 will supply a majority of the ore with lower volumes from Stage 1 and Stage 2 compared to

prior years. As mining progresses deeper in Stage 3 over 2025 and 2026, the impacts of weathering are

expected to reduce and the material feed to the plant is expected to more closely resemble current feed

from Stage 1 and 2.

• In the first quarter of 2025, Enterprise produced 4,649 tonnes of nickel, a 25% increase over the previous

quarter due to higher throughput, partially offset by lower grades. Throughput was higher as result of a ramp

up in ore supply to the plant. Additional smaller capacity articulated dump trucks were sourced and dedicated

to the softer areas of the pit where the bigger truc ks struggled to mine, especially in the wet season due

challenging underfoot conditions. Grades were impacted by a change in the mining sequence and

deployment of permanent ramps to widen the footprint, resulting in a higher proportion of transitional ore

from the South Wall area. Nickel C1 cash cost1 of $4.78 per lb is $0.16 higher than the previous quarter due

to higher freight costs. 2025 production guidance remains at 15,000 to 25,000 contained tonnes of nickel. A

4-day full maintenance shutdown of the Enterprise plant is planned in the second quarter of 2025. The focus

for 2025 will remain on ore quality and grade control through ongoing reverse circulation drilling. Key

initiatives put in place include reverting to mining 5 meter ore benches while maintaining 10 meter waste

benches. This, coupled with better grade control and monitoring, is expected to minimize ore dilution and

improve recovery.

• Production at Cobre Panamá has been halted since November 2023. Costs in the first quarter were

approximately $13 million per month, which included labour, maintenance spares, contractors ’ services,

electricity, and other general expenses, including the public engagement programs to enhance transparency

and provide accessible information about Cobre Panamá. Pres ervation and Safe Management costs

("P&SM") are expected to be in line with current rates until formal approval is received for the export of

copper concentrate and restart of the power plant.

FINANCIAL HIGHLIGHTS

Financial results continue to be impacted by the suspension of Cobre Panamá. First quarter financial results, relative

to the fourth quarter of last year, were impacted by lower sales volumes.

• Gross profit for the first quarter of $331 million was $74 million lower than Q4 2024, while EBITDA 1 of $377

million for the same period was $78 million lower.

• Cash flows from operating activities of $143 million ($0.17 per share2) for the quarter were $440 million lower

than Q4 2024, attributable to lower EBITDA 1, movements in working capital arising from increased

receivables, and higher taxes paid.

• Net debt3 increased by $257 million during the quarter to $5,787 mill ion, with total debt at $6,530 million as

at March 31, 2025. The increase in net debt3 is attributable to planned capital expenditure, mostly related to

the Kansanshi S3 project.

HEDGING PROGRAM

During the quarter, the Company continued to enter 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. Approximately half of planned production and sales in 2025, and approximately

40% of planned production and sales for the first half of 2026 are protected from spot copper price movements.

The Company recognized a $3 million gain on the copper sales hedge program in Q1 2025.

As at April 23, 2025, the Company had zero cost copper collar contracts outstanding for 272,775 tonnes at weighted

average prices of $4.14 per lb to $4.75 per lb with maturities to June 2026. Of these, there were 188,775 tonnes with

maturities to the end of 2025 with weighted average prices of $4.14 per lb to $4.83 per lb.

COPPER PREPAYMENT TRANSACTION

On April 23, 2025, on the basis of the previously -agreed commercial terms, the Company has supplemented the

sale of copper to Jiangxi Copper Company in return for an additional $500 million prepayment. This arrangement

provides for the delivery of an addit ional 50,000 tonnes of Zambian copper anode per annum payable at market

prices over the three year period. The $500 million prepaid amount will reduce in line with deliveries over the second

and third years of the supplemental prepayment agreement.

OFFERING OF 2033 SENIOR NOTES

An offering of $1,000 million 8.000% senior notes due 2033 was completed on March 5, 2025. Gross proceeds from

the notes offering, together with cash on the balance sheet, was used to repay $250 million of its revolving credit

facility to fund the concurrent partial tender offer of the 6.875% senior notes due 2027 and to pay transaction fees,

costs and expenses.

PARTIAL REDEMPTION OF 2027 SENIOR NOTES

On February 19, 2025, the Company announced the commencement of a tender offer to purchase for cash up to

$750 million aggregate principal amount outstanding of its 6.875% senior notes due 2027. On March 5, 2025, the

Company announced the early results of the tender offer for the maximum aggregate principal amount of $750

million. Settlement of the tender took place on March 6, 2025 at a redemption price of 101.200% of the principal

amount.

COBRE PANAMÁ UPDATE

Cobre Panamá currently remains in a phase of P&SM with production halted. Approximately 1,300 workers remain

on site. Implementation of the P&SM program continues to await approval from the Panamanian authorities.

During press conferences held on March 13 and March 20, 2025, Panama’s President José Raúl Mulino stated that

he had authorized the importation of supplies required for the power station, the restart of Cobre Panamá’ s power

station, and the export of the copper concentrate stored at Punta Rincón. The Company is awaiting official

communication regarding next steps.

On March 31, 2025, following engagement with the GOP’s legal counsel, First Quantum agreed to suspend the FTA

arbitration. To effectuate the suspension, First Quantum filed a request for arbitration on April 2, 2025 with the

International Centre for Settlement of Investment Disputes (“ICSID”) and notified ICSID of the agreed-to suspension.

In addition, the Company agreed to discontinue the ICC arbitration proceedings.

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 the Panamanian people.

KANSANSHI S3 EXPANSION

The Kansanshi S3 Expansion remains on track for completion in mid- 2025 and first production is expected in the

second half of 2025.

During the first quarter of 2025, early commissioning works started in parallel with completion of construction. The

majority of the 33kV distribution network and substations were energized. In addition, water was introduced to the

site, including filling the raw water pond and process water tank. The SAG mill was lined and then turned using the

gearless mill drive as part of commissioning. Construction work continues with a focus on completing the remaining

piping and electrical scope.

At the end of the quarter, the project achieved 83% construction completion and 20% of the systems have been

handed over to commissioning. Configuration of the plant control system is at 84% and is focused on functionality of

the concentrate transfer, reagent and gravity gold circuits, and functional testing of the services areas. Operational

Readiness has reached 75% completion, with significant progress made in employment and training. Training

continues, utilizing control simulator scenarios, original equipment manufacturer training, and participation in

commissioning and tie-in field work.

At the Kansanshi smelter expansion, the Wet Gas Booster Fan, which transfers gas from the smelter to Acid Plant

5, was completed. All major structural and mechanical equipment for the oxygen plant, including the coldbox, has

been installed and commissioning has commenced. Final tie- ins for the high pressure oxygen compressor at the

high-pressure leach circuit are in progress and preparing for startup. All major steel and mechanical equipment have

been installed at Acid Plant 5 with interconnecting ducting in progress. Re-assembly of the pre-heater is in progress

and testing will be carried out in the next quarter.

During the quarter, approval was received from the Zambia Environmental Management Agency for expansion of

Tailings Storage Facility 2 (“ TSF2”) in order to receive higher volumes of tailings from the expanded Kansanshi

operations. Work on the expansion of TSF2 is well on track for delivery during the commissioning of S3.

ZAMBIA POWER UPDATE

The power situation in Zambia remained constrained in the first quarter of 2025 and the declaration of national

emergency remains in place. Steady rainfall during the rainy season has provided partial relief, but reservoir levels

at Lake Kariba remain below historical norms, prompting ZESCO to continue cautious load management, albeit less

severe than at the peak of the crisis.

In response to these challenges, First Quantum has maintained and extended supplementary power arrangements

with regional third- party energy traders, easing pressure on the Zambian power grid and supporting stable

operations. As the Kansanshi S3 Expansion ramps up in the second half of 2025, the Company anticipates sourcing

up to 60% of its electricity from imports, which is expected to be a mix of renewable and non- renewable sources.

The annualized impact of the Company ’s supplementary sourcing strategy on 2025 copper C1 cash cost 1 is

estimated to be approximately $0.07 per lb, which is included in the current guidance.

In the near term, First Quantum will continue purchasing from regional power traders to ensure reliable supply, while

advancing long- term renewable power offtake agreements with domestic independent power producers. This

approach will support the Company ’s operations as well as add new capacity to the Zambian grid, benefiting both

industrial and residential users. As a reflection of this focus, during the quarter, the Company advanced a 10 -year

offtake agreement with a power trader for a 100 MW solar installation schedul ed for commissioning later this year.

1 C1 cash cost (C1) is a non-GAAP ratio, which 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”

First Quantum Minerals Ltd. 25-13

Page 8 of 14

Additionally, the previously announced planned solar and wind projects, representing a combined 430 MW of

capacity, remain on track for commissioning in late 2028.

This quarter, the Company commenced multi-year grid stabilization workstreams in collaboration with ZESCO. These

efforts aim to improve voltage stability and support the region ’s growing industrial power requirements, including

those of the Kansanshi S3 Expansion.

BOARD LEADERSHIP TRANSITION
