The Ashanti Gold Belt is responsible for most of Ghana’s 120 million oz of production as one of the most prolific gold production areas in the world. The mine is located approximately 195 km north-west of Ghana’s capital Accra. Formerly known as the Ayanfuri gold project, the mine produced in excess of 300,000 oz of gold between 1994 and 2001.
The mine contains an estimated 18.4 Mt of proven reserves graded at 1.4 g/t Au and 37.2 Mt of probable reserves graded at 1.1 g/t Au. Measured and indicated resources total 29.9 Mt graded at 2.1 g/t Au. Inferred resources have been estimated to be 62.1 Mt at 2.2 g/t.
The deposit is hosted within the Man Shield of the Precambrian aged West African Craton. The deposit flanks the western end of the Ashanti greenstone belt along the Obuasi-Akropong gold corridor. Intensely folded and faulted birimian flysch-type metasediments of the Paleoproterozoic age overlie the entire project area.
