Bisie, the Democratic Republic of Congo’s largest tin mine, produced 4,106 tons of tin in the second quarter of 2025. This fell 21% short of its initial 5,000-ton target for the period. The figure, released by operator Alphamin on Thursday, July 3, reflects the impact of a temporary shutdown in mid-March due to advancing rebel groups in the eastern region of the country.

Despite a "gradual restart from April 15" and what the company described as strong operational performance in May and June, Bisie’s output for the quarter dropped 4% compared to the 4,270 tons recorded in the first quarter of 2025.

According to calculations by Ecofin Agency, the mine produced a total of 8,376 tons of tin in the first half of the year. This represents 47% of Alphamin’s revised annual production target of 17,500 tons. While the company aims to continue operations at the site, that ambition largely depends on a lasting improvement in regional security.

On Friday, June 27, the DRC and Rwanda signed an agreement in Washington to halt clashes involving their armed forces. Talks are now expected to resume between Congolese authorities and M23 rebels in Qatar.
