Ghana's mining sector has established itself as a vital contributor to the nation's economy, accounting for over half of foreign direct investment and generating more than a third of its export revenue. The country's abundant reserves of gold, diamonds, and other critical minerals have made it a significant mining hub in Africa.

Gold remains Ghana's most lucrative mineral, contributing approximately 90% to the country's total mineral output. A nearly $500 million redevelopment project at the Obuasi gold mine, spearheaded by global mining giant AngloGold Ashanti, revived operations in January 2024 after the site had been placed on care and maintenance in 2017 due to heavy losses. Additionally, Chinese mining company Zijin Mining Group finalized an agreement to acquire Newmont's Ahafo gold mine for up to $1 billion in cash last month.

Ghana's diamond industry, predominantly located in the Birim Valley, yields around 500,000 carats annually. Since small-scale and artisanal mining commenced in 1919, the Birim River basins have produced over 100 million carats of diamonds. In 2022, Ghana recorded $4.85 billion in diamond export revenue, cementing the industry as a crucial economic pillar.

Manganese is another essential mineral in Ghana, with the country ranking as the fourth-largest global producer of manganese ore in 2023, exporting an estimated 4 million tonnes. The Minerals Commission unveiled plans for a $450 million refinery project to increase revenue from this essential mineral, developed through a strategic partnership between the Ghanaian government and a leading Chinese manganese company.

Bauxite reserves in Ghana are estimated to be around 900 million tonnes, with the government securing a $10 billion Memorandum of Understanding (MoU) with China to facilitate industry growth. This partnership includes the construction of a 4,000-km railway network and a state-of-the-art processing facility.

Ghana aims to process between 50,000 and 100,000 tonnes of iron ore locally for steel production by 2027, positioning itself as a major iron ore producer. The country possesses significant iron ore deposits near Shieni, Pudo, and Opon-Mansi, with an estimated 147 million tonnes of reserves.

Other minerals, such as copper, chrome, nickel, limestone, and quartz, also hold significant investment potential for mining firms. Ghana's copper exports contributed roughly $48.87 million to the economy in 2023, with an estimated 1.32 million tonnes of measured and indicated copper reserves, along with 1.47 million tonnes of inferred reserves.

The country is actively working to expand its chrome industry, with deposits of chromite mineralization identified in Sapoua, Wantéou, and Kantchkohoun. Ghana's nickel mining sector is largely artisanal and small-scale, with exports primarily destined for Ivory Coast and Senegal. The government is urging international investors and technology providers to introduce advanced mining techniques that will enhance production and efficiency.

Limestone deposits in Ghana are primarily found in the northern regions, with an estimated 230 million tonnes of limestone, having an average 48% calcium-oxide grade, making it a valuable resource for the industrial sector. Quartz reserves are located mainly in the Damang, Tarkwa, Ashanti, and Bibiani Shear Zones, with significant promise despite a decline in output in recent years.

In conclusion, Ghana's mining industry is poised for significant growth, driven by its diverse mineral reserves and ongoing investments in gold, diamonds, manganese, bauxite, and iron ore, as well as efforts to develop copper, chrome, nickel, limestone, and quartz. As the country seeks to modernize and expand its mining industry, there is a clear opportunity for investors and stakeholders to contribute to Ghana's economic transformation.
