Bisie
Bisie is a tin deposit in the Walikale territory, province of North Kivu, in the Democratic Republic of the Congo (DRC), although the name has also been used to include the nearby village of Manoire. It used to be an illegal source of an estimated 15,000 tons of tin, or 4% of global production. At the present time, artisanal activity has been suspended, and Alphamin Resources Corp., a Mauritius-based exploration company, is leading an exploration program on the site.
