Panama approved limited restart at Cobre Panam through $250mn stockpile plan

Panama has approved a US$250 million program by First Quantum Minerals to process stockpiled copper ore at the Cobre Panam mine, in a move aimed at mitigating environmental risks while generating revenue without resuming fresh mining activity. The decision marks a calibrated attempt to manage the economic and environmental fallout following the mines closure in 2023.

Cobre Panam and its global significance

Cobre Panam was among the largest copper mines globally, producing nearly 0.4 mnt of copper and accounting for around 1.7% of global supply. Its scale made it a critical contributor to the global copper market, particularly at a time when demand is rising due to electrification and energy transition trends. Domestically, the mine played a central role in Panamas economy, contributing significantly to exports and government revenues.

However, operations were halted in late 2023 after widespread nationwide protests and a Supreme Court ruling that declared its mining contract unconstitutional. Public opposition was driven by environmental concerns and dissatisfaction with the contractual framework. The ruling forced an abrupt shutdown, disrupting both domestic economic activity and global copper supply chains.

The closure had an immediate tightening effect on the global copper market, exacerbating supply-side constraints and increasing uncertainty. For First Quantum Minerals, the impact was particularly severe, with nearly 40% of its total revenue wiped out. Downstream industries reliant on copper, including construction, power, and electric vehicles, also faced heightened price volatility and procurement challenges as supply tightened.

Government allows limited processing of stockpile

The approval focuses solely on processing already extracted ore, rather than restarting mining operations. The plan allows for the treatment of approximately 38 million tonnes of stored ore, containing about 70,000 tonnes of recoverable copper, using existing infrastructure. No new mining activity is permitted, underscoring that this is a limited and temporary measure rather than a full operational restart.

The primary driver of the decision is environmental risk mitigation, as prolonged ore storage can lead to acid rock drainage, potentially contaminating soil and water. Processing the material helps reduce these risks while enabling limited economic activity without reopening the mine. At the same time, the program is expected to generate over 1,000 direct jobs, support the export sector, add incremental copper supply, and create immediate government revenues through royalties. While volumes remain modest, it offers short-term relief to both local and global supply chains.

From a policy perspective, the government has adopted a no-cost, revenue-sharing model, with the entire US$250 million investment borne by the company, while the state benefits from royalty income, making it a value-capture approach during the closure phase.

While the approval represents an interim solution that balances environmental responsibility, economic recovery, and political considerations, it does not resolve the mines long-term future. Any potential return to full-scale mining operations will require a new legal framework and broader public support for the project.
