    Gold plays an important role in the economy of Ghana, with up to 1500 tons of gold produced throughout its history. Ghana has five major types of gold deposits. Native gold in steeply dipping quartz veins in shear zones at the margins of Birimian basins, arsenopyrite in sulfur bodies, disseminated mineralization in basin granitoid rocks and alluvial placer gold in river deposits in gravel are major sources of gold.

    Gold plays an important role in the economy of Ghana, with up to 1500 tons of gold produced throughout its history. Ghana has five major types of gold deposits. Native gold in steeply dipping quartz veins in shear zones at the margins of Birimian basins, arsenopyrite in sulfur bodies, disseminated mineralization in basin granitoid rocks and alluvial placer gold in river deposits in gravel are major sources of gold. In some cases, ancient placer gold has mineralized and reconstituted along wit other minerals such magnetite and hematite in the quartz-pebble conglomerates of the Tarkwaian Group. From the late 15th century until the mid 19th century, two-thirds of Africa's gold production was estimated to have originated from the Gold Coast. Annual production in the early 1980s was 12,000-15,000 kg. The major primary gold lodes are found in the shear zone between the Lower Birimian phyllites and Upper Birimian greenstones, and consist of quartz veins and lenticular reefs. The gold is usually accompanied with arsenopyrite. Mines along the west side of the Tarkwa syncline include the Obuasi Gold Mine, and those located at Prestea and Konongo. Sedimentary gold is found in the Banket conglomerate near the base of the Tarkwaian. This includes the Iduapriem Gold Mine, Teberebie Mine, and those located at Tarkwa, and Abosso, located along the eastern margin of the Tarkwa syncline. Accompanying minerals include rutile, zircon, and detrital hematite, all within gravel horizons. Placer gold is mainly dredge mined along the Ofin River at Dunkwa-on-Offin. Additionally, eluvium, beach sands, terraces, and Pleistocene stream sediments contain alluvial gold. Significant diamond deposits are found in river gravels in the central and eastern part of Ghana, although the country does not have kimberlite pipes where diamonds formed in the geologic past.
