Ghana Manganese Company (GMC) has announced plans to invest US$450million in a manganese refinery at Nsuta near Tarkwa, Western Region, in a major step for the country’s drive to add value to its mineral resources.
The proposed refinery is expected to boost industrial processing, create thousands of jobs and strengthen the country’s push to move beyond the export of raw minerals.
The project was unveilled by GMC’s Deputy Managing Director, Sun Yuanwei, during the inauguration and welcome ceremony of MV CSB Years – the largest bulk carrier ever to berth at Port Takoradi.

Mr. Sun said the refinery forms a central pillar of GMC’s long-term growth strategy, signalling a deliberate shift from exporting unprocessed manganese ore to developing a fully integrated processing value chain in Ghana.
“Our objective is to move beyond mining into industrial processing,” he said. “This refinery will create employment, deepen local content and deliver sustained socio-economic benefits to host communities and the national economy.”
He explained that the Nsuta enclave was selected because of its proximity to GMC’s mining operations, existing infrastructure and access to port facilities – factors expected to reduce logistics costs and improve operational efficiency.
The Director of Port Takoradi, Captain James Richmond Quayson, described the refinery as a strategic complement to recent investments in port infrastructure and capacity expansion.
He noted that downstream mineral processing projects are essential to sustaining port growth and enhancing Takoradi’s role as an industrial logistics hub.
“The refinery will significantly increase cargo throughput and reinforce the port’s importance in supporting large-scale mineral exports,” he said, adding that such projects justify continued investment in port facilities.
President of the Western Regional House of Chiefs, Nana Kobina Nketsia V, said the proposed refinery will be a game-changer for both the region and Ghana’s broader industrialisation agenda.
“This is one of the most significant investment signals the region has received in a long time,” he said, urging GMC and its partners to prioritise strong local participation, skills development and environmental responsibility.
