COBRE PANAMA UPDATE

On January 6, 2025, Panama’s Ministry of Environment released the Terms of Reference for an Environmental

Audit of the Cobre Panama mine. The audit will be conducted by international experts to provide updated

information on the status of the mine and support the Government of Panama’s decision-making. The Terms of

Reference for the Environmental Audit were submitted to a public consultation process that concluded on February

7, 2025. Separately, an independent audit of the copper concentrate stored on site was completed by the

government in December 2024, which confirmed the quantities of copper concentrate stored at the facilities.

On January 12, 2025, the Minister of Environment and the Minister of Public Security conducted a site visit of

Cobre Panama. During the visit, the ministers toured the mine, process plant, port and power plant facilities to

inspect the upkeep of the mine and the status of the surrounding communities and the environment. The visit also

enabled the ministers to inspect 7,960 tons of ammonium nitrate stored at the mine’s Punta Rincon port. The

Minister of Environment subsequently stated that the ammonium nitrate should be exported, which commenced by

road in January 2025. The P&SM plan is not yet approved by the Government of Panama.

In parallel with the upkeep of the mine site in advance of the approval of the P&SM plan, the Company has

continued a comprehensive program of public outreach across the country to enhance transparency and provide

accessible information about Cobre Panama. Since the beginning of 2024, these outreach efforts have reached

over 40,000 Panamanian citizens through site visits and briefings conducted in universities, schools, and public

spaces at more than 150 events nationwide. Additionally, over 300,000 Panamanians have participated in an

online virtual tour of the mine, further broadening public engagement.

The Government of Panama applied to the Arbitration Panel of the International Chamber of Commerce

proceedings to request an extension of its submission dates following the replacement of external legal counsel

and on the basis that the new government required time to assess the situation concerning the mine. A final

hearing for this matter is now scheduled for February 2026.

The Company reiterates that arbitration is not the preferred outcome for the situation in Panama and it remains

committed to dialogue with the Government of Panama 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.

During the fourth quarter of 2024, the gearless mill drive installations were completed and the 33kV overhead line

and substation was commissioned. Civil and structural workstreams are substantially progressed. Work in priority

mechanical areas continues together with completion of piping and electrical systems to allow progress into early

commissioning of major systems.

As at the end of 2024, the S3 Expansion project achieved 62% construction completion of the process plant and

commenced early commissioning work. System configuration of the plant control system is at 80%, focused on

functionality of cleaner and reagent circuits, and functional testing of services areas. Operational readiness

achieved 62% completion with training of personnel on the process simulator.

At the Kansanshi smelter expansion, the new waste heat boiler condenser and 5th train of wet electrostatic

precipitators were completed and successfully commissioned. Installation of the high pressure oxygen compressor

was completed with commissioning in progress. All major oxygen plant equipment arrived on site and installation is

progressing. Acid Plant 5 civil work was completed with structural mechanical and piping installation in progress.

ZAMBIA POWER UPDATE

Zambia’s energy situation remained challenging through the fourth quarter. However, the Company’s proactive

strategy of securing supplementary power, primarily from Southern Africa, allowed the Company to maintain

normal operations with minimal power interruptions. The annualized impact on 2025 C1 copper cash cost! is

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

Zambia has received steady rainfall since the start of this rainy season in early November, which will continue

through to the end of March. Lake Kariba levels remain significantly lower than prior years due to the pulldown of

lake levels earlier in 2024, although a modest recharge has allowed water levels to rise 6% since the onset of rainy

season. As such, the Company is not planning for a full return to normal in-country hydroelectricity power

generation in 2025. To address the likely shortfall, the Company has put sourcing plans in place for 2025 to ensure

that reliable electricity supply is available for its operations, including the start-up of the Kansanshi S3 Expansion

project.

First Quantum will continue collaborating with the national electricity utility, ZESCO, and third-party energy

providers to maintain a secure energy supply. Longer term, the 430 MW solar and wind project with TotalEnergies

and Chariot Energy, together with new hydropower initiatives in Zambia’s Northwest and Northern Provinces,

remain on schedule for commissioning by 2028. These developments are expected to bolster both First Quantum’s

and Zambia’s overall energy security.

BOARD LEADERSHIP TRANSITION

Following over a decade as Lead Independent Director and two years as Chair of the Board, Robert Harding will

retire at the conclusion of the 2025 Annual General Meeting on May 8, 2025. At that time, Kevin McArthur, a

Director since 2021, will succeed him as Chairman.

“It has been a privilege to serve on First Quantum’s Board for the past twelve years and witness the Company’s

transformation,” said Robert Harding. “This announcement reflects the Board’s ongoing commitment to renewal,

ensuring a strong mix of experience and fresh insight over time. Having worked closely with Kevin, | am pleased

with the Board’s decision to appoint him as the next Chair. His deep industry knowledge and leadership experience

make him well suited for the role, and | have full confidence in him and the Board to guide the Company’s future.”

Kevin McArthur commented, “On behalf of the Board and the Company, | want to sincerely thank Bob for his

leadership and dedication over the years. He has helped guide First Quantum through some of its most

challenging moments, always with a steady hand and a clear vision for the future. His contributions have been

invaluable, and we wish him all the best in his retirement.”

“| wish to personally thank Bob for his guidance, support and impact both as a Board member and, in particular,

during the last two years as Chair during a period of challenge and change at First Quantum,” said Tristan Pascall,

Chief Executive Officer. “I am looking forward to working with Kevin in a much closer capacity in his new role and |

know the Company will be well served by his leadership of the Board. It is very healthy that we continue the

ongoing Board succession process to position the Company for its strategic objectives for 2025 and for the coming

years of ongoing disciplined growth.”

Q4 2024 OPERATIONAL HIGHLIGHTS

Total copper production for the fourth quarter was 111,602 tonnes, a 4% decrease from Q3 2024 as a result of

lower production at the Zambian operations. Copper C1 cash cost! was $0.11 per Ib higher quarter-over-quarter at

$1.68 per lb, reflecting lower copper production volumes. Copper sales volumes totalled 111,613 tonnes,

approximately 11 tonnes higher than production.

¢ Kansanshi reported copper production of 48,139 tonnes in Q4 2024, 1,671 tonnes lower than the previous

quarter. While feed grades remained high with the continued swap of the mixed and sulphide mills,

throughput was lower due to a planned maintenance plant shutdown in the sulphide and mixed circuits.

Gold production continued to be strong with 29,787 ounces of gold produced in the fourth quarter. Copper

C1 cash cost’ of $1.21 per Ib was $0.08 lower quarter-over-quarter as a result of the drawdown of

stockpiles. Production guidance for 2025 remains unchanged at 160,000 to 190,000 tonnes of copper and

100,000 to 110,000 ounces of gold. 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 56,560 tonnes in Q4 2024, 1,852 tonnes lower than the previous

quarter due to lower grades. Throughput levels, however, improved quarter-over-quarter with December

2024 reporting the highest monthly throughput since October 2022, benefiting from the development of

Stage 3 (Western Cut-back) that increased availability of softer material, improved availability of the

primary crushers and improved fragmentation of the ore. Stripping in Stage 4 (Final Eastern Cut-back)

commenced during the fourth quarter. In-pit crusher 1 was successfully relocated and commissioned at the

end of December, two months ahead of schedule. Copper C1 cash cost! of $2.11 per Ib was higher than

the preceding quarter as a result of lower production volumes and higher tolling and freight costs. Copper

production guidance for 2025 remains unchanged at 200,000 to 230,000 tonnes of copper. In 2025, the

focus at Sentinel will be on increasing mill throughput with various ongoing initiatives in place to optimize

blast fragmentation, maintain full stockpiles, and improve milling rates and flotation recovery. Grades are

expected to be lower than 2024, in line with the pit development sequence. Stage 3 will supply a majority

of the ore with lower volumes from Stage 1 and Stage 2 compared to prior years. The relocation of in-pit

crusher 2 has been planned for the 2025 year, including installation of an innovative rail-driven conveyor

system that is expected to result in reduced power and maintenance costs. A major overhaul is planned for

a rope shovel during the second quarter. Stripping will continue in Stage 4, with ore expected to be

available in 2026. Bringing forward production from Stages 3 and 4, along with a balanced increase in

waste stripping, is expected to de-risk future ore supply to achieve an optimal and sustainable balance of

grades and volumes during the life of the mine.

+ For the fourth quarter of 2024, Enterprise produced 3,720 tonnes of nickel at a nickel C1 cash cost’ of

$4.62 per lb. Sources of nickel sulphide ore during the quarter were impacted by weathering and alteration

in a fault line in the Southern Wall of the pit and the presence of nickel silicates. In the second week of

December, the Enterprise flotation circuit was switched to treat copper ores from the Sentinel mine while

the fault area was mined through and the altered material was stockpiled separately for blending with fresh

nickel sulphide ore. The relevant area in the Southern Wall was mined out in early January 2025 and nickel

feed to the Enterprise concentrator resumed. 2025 Production guidance is 15,000 to 25,000 contained

tonnes of nickel. The focus for 2025 at Enterprise will be on optimizing the development of the pit to supply

feed volumes to the plant. Additional reverse circulation drilling will be performed to obtain additional

geological information. Grade is expected to be lower than 2024 while recoveries will benefit from a better

understanding of the geological characteristics of the ore.

« Production at Cobre Panama has been halted since November 2023. During the quarter, the process plant

assets inspection frequency was maintained at 56 days and the equipment start-up frequency remained

unchanged at 14 days. In addition to asset preservation, a key focus continues to be on maintaining the

environmental stability for all areas of the site and compliance with the environmental and social impact

study for the project, which remains in force. Primary activities are in cleaning and maintenance works at

sediment ponds, managing surface water at the waste dump and low-grade stockpiles, and treatment of

water to manage the pH levels. Costs in the fourth quarter were approximately $13 million per month,

which included labour, maintenance spares, contractors’ services, electricity, other general expenses,

including the public outreach program across the country to enhance transparency and provide accessible

information about Cobre Panama. The Company is actively managing the maintenance costs of Cobre

Panama and will adjust the level of employment and the costs of these activities according to the

conditions on the ground in Panama. Approximately 121 thousand dry metric tonnes of copper concentrate

remain onsite following the 2023 disruptions at the Punta Rincén port. P&SM costs are expected to be

between $12 million to $13 million per month.

FINANCIAL HIGHLIGHTS

Financial results continue to be impacted by the suspension of Cobre Panama. Fourth quarter financial results,

relative to the third quarter, were impacted by lower copper and gold sales volumes along with a lower realized

copper price’.

$455 million for the same period was $65 million lower.

* Cash flows from operating activities of $583 million ($0.70 per share’) for the quarter were $323 million

higher than Q3 2024, attributable to favourable movements in working capital.

* Net debt* decreased by $61 million during the quarter to $5,530 million, with total debt at $6,342 million as

at December 31, 2024. The decline in net debt? is attributable to positive movements in EBITDA?

contribution and working capital, partially offset by interest paid and planned capital expenditure, mostly

related to the Kansanshi S3 project.

HEDGING PROGRAM

Consistent with prior quarters, the Company entered into additional 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.

The Company recognized a $13 million gain on the copper sales hedge program in Q4 2024 and a $34 million gain

for the year.

At February 11, 2025, the Company had zero cost copper collar contracts outstanding for 242,641 tonnes at

weighted average prices of $4.14 per lb to $4.81 per Ib with maturities to June 2026. Approximately half of planned

production and sales in 2025 and over 90% of the same in 2026 remain exposed to spot copper prices.
