Ghana Manganese Company Ltd (GMC) is the only manganese producer and exporter in Ghana.  The company is a privately-owned mining company (consolidated Minerals Africa Limited -90% and Government of Ghana-10% free carried) that holds a mining concession for manganese ore over an area of 170 square kilometers in and around Nsuta in the Western Region of Ghana, less than 3% of which has been mined to date.

Nsuta is known for its unique high-grade carbonate ore, which is considered to have one of the highest manganese-to-iron ratio ores in the market (Mn: Fe ~31) and is low in phosphorous, alumina, and other heavy metal impurities, making it well-suited for both alloy and manganese metal production.

As an experienced owner-operator with a strong focus on operational excellence and innovation, the company targets to be at the bottom of the cost curve of global manganese producers. It has 3 existing pits in total (Pits A, B, and C) with operations currently active in Pit C.

To maintain its position as an important market leader in mining and exporting manganese ore.
To be an internationally successful operating mining company, undertaking safe mining practices combined with cost-effective production methods. To achieve this, we recruit, retain, and develop skilled employees.
