Cobre Panama restart and 1,000 new jobs: production and stockpile outlook for mine planners
Reviewed by Tom Sullivan

First reported on MINING.com
30 Second Briefing
First Quantum Minerals is ramping up its Cobre Panama restart, commissioning the first of three milling circuits and producing 3,216 tonnes of copper concentrate from 2.1 million tonnes of stockpiled ore in Q2, while adding about 1,000 jobs to lift direct site employment to roughly 3,000. The mine’s 38‑million‑tonne stockpile holds an estimated 70,000 tonnes of recoverable copper, supporting 2026 guidance of 30,000–40,000 tonnes from stockpile processing and roughly 12 months of throughput at current rates. Formal negotiations with Panama are nearing, with options including a joint venture with a state-owned miner, a 60–65% First Quantum stake, or a lease-back model.
Technical Brief
- First Quantum suspended a US$20 billion arbitration claim against Panama while restart negotiations advance.
- Cobre Panama has been idle since late 2023 following Panama’s Supreme Court ruling the 20‑year contract unconstitutional.
- The shutdown removed more than 1% of global copper supply and ~40% of First Quantum’s revenue.
- Panama’s government is assessing JV options including a 60–65% First Quantum stake with the state holding the balance.
- An alternative structure under review is a lease‑back model where the state owns the asset and receives royalties and taxes.
- Environmental audit results show 87.7% compliance with existing environmental commitments at the operation.
- President José Raúl Mulino’s administration has already authorised sales of stockpiled concentrate and restarted the site power plant.
- Site workforce rose from ~2,350 in early April to ~3,000 by end‑June, supported by the Suma tu Talento campaign.
- Over half of new hires are from local communities, with women representing 17% of recent recruitment.
- The shutdown was estimated to erase about 4.5% of Panama’s GDP, underlining sovereign‑scale exposure to single‑asset disruptions.
Our Take
The 87.7% environmental compliance figure at Cobre Panama aligns with the environment ministry’s ~88% compliance assessment reported on 19 June 2026, suggesting the restart and hiring push are being sequenced to demonstrate regulatory progress ahead of any political decisions on long-term copper operations in Panama.
The arbitration claim of up to US$20 billion against Panama, combined with a potential 60–65% stake in any new partnership structure at Cobre Panama, gives First Quantum significant leverage but also raises the likelihood that any restart terms will be closely tied to demonstrable environmental performance and local employment outcomes under programmes like Suma tu Talento.
