Cobre Panama Stockpiled Ore Approval Gives First Quantum Limited Copper Recovery Path

First Quantum

Cobre Panama stockpiled ore processing has been approved by Panama’s government, giving First Quantum Minerals a limited route to recover copper from material mined before the project was shut down. The approval allows removal, processing and export of stockpiled ore from the closed copper mine.

The site will process about 38mn t of stockpiled ore containing roughly 70,000t of recoverable copper. First Quantum said the work will use existing crushers, conveyors and flotation circuits, with initial processing running at about one-third of nameplate capacity.

Cobre Panama stockpiled ore processing does not restart mining. The company said the work will not involve new mining, drilling or blasting, making the approval a controlled processing decision rather than a full mine reopening.

Stockpile Treatment Reduces Environmental and Economic Pressure

The approval gives Panama and First Quantum a practical way to manage material already sitting at the site. Processing the stockpiled ore could reduce environmental risks linked to long-term storage while generating royalties and other payments for Panama.

First Quantum plans to spend about $250mn on preparation, mainly to rebuild inventories and supply chains. The company is also rehiring about 1,000 workers, raising the site workforce to around 3,000 across processing, maintenance, environmental work and logistics.

The move follows earlier permits to ship stranded copper concentrate and restart a 300MW coal plant at the site. Panama linked these steps to easing the economic impact of the mine’s closure.

Copper Supply Impact Remains Limited Without Mine Restart

Cobre Panama was a major global copper asset before its closure in 2023. The mine produced 331,000t of copper in its final year, equal to about 1.5% of global supply, before protests and a supreme court ruling forced the shutdown.

The closure removed close to 40% of First Quantum’s revenue, increasing the company’s dependence on copper operations in Zambia and smaller nickel and gold output. Processing Cobre Panama stockpiled ore will provide some near-term value, but it cannot replace the output of a fully operating mine.

First Quantum dropped a $20bn arbitration claim last year to allow talks with Panama’s government to resume. However, Panama has made clear that stockpile treatment does not resolve the mine’s long-term future. Any return to mining would require a new political and legal settlement.

The Metalnomist Commentary

Panama’s decision is a compromise between environmental management, economic recovery and political caution. Cobre Panama stockpiled ore processing may release some copper, but the real supply question remains whether one of the world’s major copper mines can ever return under a new legal framework.
