Alphamin Resources Ltd said it expects to produce between 18,000 and 18,500 tons of tin in 2025 at its Bisie mine in the Democratic Republic of Congo (DRC). The company raised its April forecast of 17,500 tons, according to an operational update published on October 8.

The operator initially planned to produce 20,000 tons in 2025. However, Alphamin cut its target earlier this year after halting operations in March because of rebel activity in eastern Congo.

The company reported a cumulative output of 13,566 tons in the first nine months of 2025. It expects to add around 5,000 tons in the fourth quarter, which would bring annual production to the new range of 18,000–18,500 tons.

“The Company expects to produce approximately 5,000 tons of contained tin during the final quarter of the financial year which, together with its year-to-date production of 13,566 tons, increases tin production guidance for FY2025 to between 18,000 and 18,500 tons (17,500 tons previously),” the company said in its update.

The Bisie mine produced 5,190 tons of tin in the third quarter, a 26% increase from the second quarter, which had been impacted by the temporary shutdown. The company attributed the rebound to “processing facilities continuing to deliver good results.”

Alphamin reported annual output of 17,324 tons in 2024. The company said final fourth-quarter results will determine whether the revised 2025 target is fully achieved.
