These deposits represent a relatively new style of gold mineralization in the Ghanaian Birimian. The mineralization consists of quartz veins/stockworks and pervasive alteration zones within the granitoids in brittle structures. The ore mineral assemblage is mainly composed of pyrite and arsenopyrite, with minor chalcopyrite, sphalerite, and rutile.
Under present tropical conditions, other elements associated with Birimian gold mineralization, notably copper and arsenic, are highly mobile to remain in residual soils. However, manganese, like iron, remains in residual soils as oxides and could be a useful pathfinder element in the search for gold in tropical lateritic soils derived from Precambrian greenstones.
The illegal gold mine is hidden just past a thick grove of cocoa trees, a little ways off the twolane road through Sagyimase, Ghana, a rural town a couple hours drive north of the West African
The Ashanti belt of Ghana is the key district of gold mineralization in the Paleoproterozoic terrane of West Africa. The area considered in southwest Ghana is covered by lithologies of the volcanicsedimentary Birimian Supergroup and the overlying clastic sedimentary Tarkwaian Group which were jointly folded and metamorphosed under greenschist facies conditions during the Eburnean

The Oppon Manso iron ore reserves were discovered by the Ghana Geological Survey in 1963 located on 15 hills over 24km strike .
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008.
