Metamorphic carbonate-type manganese deposit, discovered in 1914 and mined from an open pit since 1917. The deposit consists of a manganese oxide zone, which is now mined out, and an underlying manganese carbonate zone which was discovered in 1968.
Owned by the African Manganese Co. from 1923, then owned by Ghana National Manganese Corp. Produced 267,996 tons of ore (1984).
Located about 20 km SE of Tarkwa.
