Loulo-Gounkoto Gold Mine Complex; Loulo Mining District; Loulo gold project


A gold mine complex in western Mali, 220 km south of Kayes.
Operated by Randgold Resources Ltd (2017)

The 17+ Moz Loulo Au mining district in the Kédougou- Kéniéba inlier in western Mali and eastern Senegal is one of the most richly endowed orogenic Au districts in the West Africa craton (Fig. 1). It hosts three major, multimillion-ounce deposits, including Gara, Yalea, and Gounkoto, and numerous satellite deposits that typically contain <1 Moz Au (e.g., Baboto, Faraba, Loulo 3, Loulo 2, P64, and P129).
