Bisie, comprising the Mpama North and Mpama South operations, is the largest tin mine in the Democratic Republic of the Congo (DRC). In 2023, the mine delivered 12,568 tonnes, representing 4.5% of the world’s production.

Alphamin Resources, the Mauritius-based company that owns the Bisie project, recently published its Q2 2024 results. The company produced 4,027 tonnes of tin over the period, thus totaling 7,169 tonnes in H1 2024.

This is 13% more than in H1 2023, a surge spurred by the Mpama South treatment plant, commissioned last May. 

The company is targeting between 17,000 and 18,000 tonnes of tin this year, compared to 12,568 tonnes in 2023. With Mpama North in operation for several years now, Mpama South is one of Bisie's two operations. With this mine alone, the DRC supplied 4.5% of the world's tin mine production last year, according to the International Tin Association.

According to official statistics, Congolese production of cassiterite (ore containing tin) reached 33,558 tonnes in 2023.
