First Quantum Minerals Finalizes Draft Concession Agreement With Government of Panamá on Future of Cobre Panamá

(In United States dollars, except where noted otherwise)

First Quantum Minerals Ltd. ("First Quantum" or the "Company"), today announced that its Panamanian subsidiary, Minera Panamá, S.A. ("MPSA"), has agreed and finalized the draft of a concession contract (the "Proposed Concession Contract") with the Government of Panamá (the "Government") for the Cobre Panamá mine.

The Proposed Concession Contract meets the objectives outlined by the Government in January 2022 related to government revenues, environmental protections and labour standards. It also provides legal protections necessary to both parties to ensure durability and stability. The Proposed Concession Contract is subject to a 30-day public consultation process and approvals by the Panamanian Cabinet, Comptroller General of the Republic and the National Assembly. The Proposed Concession Contract will have an initial 20-year term, with a 20-year extension option and additional extensions for the life of mine.

Additionally, the Panamá Maritime Authority has confirmed that it will issue a resolution today for MPSA to resume concentrate loading operations at the Punta Rincón port. Ore processing is expected to resume and restore the mine to full production levels over the next several days.

Tristan Pascall, Chief Executive Officer, said, "After a lengthy and arduous negotiation process, the finalized Proposed Concession Contract outlines the basis for the future of Cobre Panamá for all stakeholders, including the Government, our investors and the country of Panamá. I am pleased that we now have a pathway to continuing our ongoing substantial investments in the country. I wish to thank our Panamanian and international employees and their families and our suppliers for their patience and resilience during this time. We now await formal approval of the Proposed Concession Contract and look forward to a long and constructive partnership with the Government of Panamá for many years to come."
