Gold accounted for some 80% of mining activity in the mid-2000s, while there remain considerable proven reserves of other minerals not currently exploited. Gold has become Mali's largest export, after cotton—historically the basis of Mali's export industry—and livestock. The emergence of gold as Mali's leading export product since 1999 has helped mitigate some of the negative impacts caused by fluctuations in world cotton markets and loss of trade from the Ivorian Civil War to the south. Large private investments in gold mining include Anglogold-Ashanti ($250 million) in Sadiola and Yatela, and Randgold Resources ($140 million) in Morila – both multinational South African companies located respectively in the north-western and southern parts of the country.
