The mining industry of Mali is dominated by gold extraction. Mali is ranked the third-largest gold producer in Africa, with 13 international mining companies operating in the country. Gold, followed by cotton, is the top export item making a large contribution to the economy of the country.
Apart from gold, diamond is also extracted from the Kéniéba region and many more prospected kimberlite pipes with diamondiferous are yet to be put into the production stage. Phosphate is mined from the Tilemsi Valley, but to a limited extent. Other established mineral resources are Bauxite reserves of 1.1 billion tons from three locations between Kéniéba and Bamako; iron ore reserves of 146 million tons of 50% Fe grade, mostly from Ble; and manganese reserve of 10 million tons at Asongo.
Semi-precious stones extracted are amethyst, epidote, garnet, prehnite, and quartz. Some amount of diamond is also extracted as a byproduct during gold extraction.
