GOVERNMENT OF PANAMA APPROVES PROCESSING OF STOCKPILED ORE AT
COBRE PANAMÁ
(In United States dollars, except where noted otherwise)
Toronto, Ontario ( April 7, 2026) - First Quantum Minerals Ltd. (“ First Quantum” or the “ Company”) (TSX: FM)
announces that the Government of Panama (“GOP”) has formally approved the removal, processing and export of
stockpiled ore at Cobre Panamá (“Processing Program”) that was extracted prior to the suspension of operations.
The processing of stockpiled ore is intended to mitigate environmental and operational risks associated with
prolonged on‑site storage, including the potential for acid rock drainage, while also providing important feed material
to the tailings management facility. This activity does not constitute a reopening of the mine and will not involve any
new drilling, blasting, or reactivation of mining operations.
“We welcome the formal approval to proceed with the removal and processing of stockpiled ore, which represents
an important step in the responsible environmental management of Cobre Panamá, particularly with respect to water
and tailings stewardship. The Processing Program is expected to create more than 1,000 direct jobs and generate
meaningful economic contributions through royalties and local economic activity .” said Tristan Pascall, Chief
Executive Officer of First Quantum.
The total stockpile is estimated at approximately 38 million tonnes of mineralized ore at varying grades, containing
approximately 70,000 tonnes of recoverable copper. The Company is focused on the safe and responsible execution
of preparation works ahead of the commencement of stockpile processing:
• Rebuilding the workforce : Cobre Panamá has initiated the hiring and training of approximately 1,000
additional employees to expand the current workforce to 3,000 employees . Employment is expected to be
generated across maintenance, processing, environmental management, logistics, and support services.
First Quantum intends, where possible, to prioritize the re‑ employment of local community members and
former Cobre Panamá workers. In addition, the Processing Program is expected to support further
employment through contractors and indirect jobs across equipment supply, transportation, logistics, food
services, and other local industries.
• Re‑establishing critical supply chains and inventory replenishment: Cobre Panamá has begun
re‑establishing critical supply chains, including with local Panamanian suppliers , for the replenishment of
consumables, spare parts, reagents, fuel, and other essential materials required for safe and efficient
processing activities.
• Site readiness and facilities preparation: The Processing Program will utilize the existing in‑pit crushers,
conveyors, process plant, and flotation circuit. Inspections conducted to date indicate that minor repairs are
required, primarily related to the flotation and concentrate handling circuit s. While the Processing Program
will allow for testing of all three milling circuits, it is expected that facilities will initially operate at approximately
one‑third of nameplate capacity in order to ensure the highest quality operations as is practically achievable
after a long period of shutdown.
The Company expects these preparation and pre- commissioning works to require up to three months until the
commencement of stockpile processing. The required capital is estimated at approximately $250 million, primarily
comprised of working capital to replenish inventories. The processing of stockpiled ore will be carried out in close
coordination with the GOP and in strict compliance with the approved Preservation and Safe Management plan.
