First Quantum Copper Output Falls But Cobre Panama Stockpile Lifts 2026 Guidance

First Quantum

First Quantum copper output declined in the first quarter as lower production from the company’s Zambian mines offset a sharp increase in nickel output. The Canadian miner produced 96,469t of copper in January-March, down 3.2% from a year earlier.

First Quantum copper output was weaker at both Kansanshi and Sentinel, the company’s two main operating copper assets in Zambia. Copper sales also fell by 11.7% to 90,049t because of shipment timing and inventory replenishment at Kansanshi after stronger sales in the previous quarter.

First Quantum copper output guidance for 2026 was raised despite the weaker first-quarter result. The company increased its full-year copper production outlook to 405,000-475,000t after Panama approved the processing and export of stockpiled ore at the closed Cobre Panama mine.

The approval changes the near-term production picture, but it does not reopen Cobre Panama. The mine remains closed after protests and a court ruling in 2023 found its operating contract unconstitutional.

Zambian Mines Weaken as Grades and Recoveries Pressure Output

Kansanshi produced 45,345t of copper in the first quarter, down 2.6% from a year earlier. The decline reflects the challenge of maintaining output from mature large-scale copper operations.

Sentinel produced 45,252t of copper, down 2.4% on the year. Lower feed grades and weaker recoveries reduced output at the mine.

These results show how copper supply can weaken even when operating assets remain active. Mine grades, recovery rates, mill performance and shipment timing all influence quarterly supply.

The weaker sales figure also matters. First Quantum sold 90,049t of copper in the quarter, below production, because of shipment timing and the need to rebuild Kansanshi inventories.

For copper markets, Zambia remains important because it is one of Africa’s key producing regions. Stable output from Kansanshi and Sentinel supports global supply at a time when buyers are increasingly focused on secure copper sources outside more politically sensitive routes.

First Quantum’s nickel production moved in the opposite direction. Output rose by 165.4% on the year to 12,340t, supported by higher grades and recoveries.

The nickel increase improves the company’s diversified metals profile. But copper remains the strategic core of First Quantum’s business and the main driver of market attention.

Cobre Panama Stockpile Approval Adds Near-Term Copper Supply

First Quantum raised its 2026 copper production guidance after Panama approved the removal, processing and export of stockpiled ore at Cobre Panama. The site will process around 38mn t of stockpiled ore containing about 70,000t of recoverable copper.

This approval gives First Quantum a short-term supply and cash-flow opportunity from material already mined before the shutdown. It does not involve new mining, drilling or blasting.

Cobre Panama was one of the largest copper mines in the Americas before its closure. It produced 331,000t of copper in its final year, equal to about 1.5% of global supply.

The mine’s shutdown removed a major source of copper supply and had a severe impact on First Quantum’s revenue base. The stockpile processing approval partly eases that impact, but only for material already on site.

The long-term future of Cobre Panama remains unresolved. Any return to mining would require a new political and legal settlement with Panama.

This distinction is important for copper markets. Stockpile processing can add near-term units, but it does not restore the full mine or solve the broader supply loss from the 2023 closure.

First Quantum kept its 2026 nickel production guidance unchanged at 30,000-40,000t. That suggests the main guidance change is tied directly to Cobre Panama’s approved stockpile treatment.

For investors and copper buyers, the company’s outlook now depends on two tracks. Zambia must stabilise operating performance, while Panama determines how much value can be recovered from Cobre Panama without reopening the mine.

The Metalnomist Commentary

First Quantum’s guidance increase is a stockpile story, not a full Cobre Panama recovery story. The approval adds useful copper units, but the real strategic question remains whether Panama and First Quantum can ever rebuild a legal framework for long-term mining.
