Kinross acquired its 100% interest in the Tasiast gold mine on September 17, 2010 upon completing its acquisition of Red Back Mining Inc. The Tasiast mine is an open pit operation located in north-western Mauritania and is approximately 300 kilometres north of the capital Nouakchott.

Tasiast is located within an extensive gold system that is largely underexplored. The deposit is open along strike and at depth. Gold mineralization occurs in two parallel trends: the Piment Zone, which is continuous over a 4.5 kilometre strike length, and the Greenschist Zone (West Branch), with a strike length of approximately 1.5 kilometres.

Tasiast began commercial operations in 2008. Current mining operations consist of conventional open pit mining methods. High grade ore processing is based on three stage crushing, ball milling, and a carbon-in-leach circuit. Lower grade oxide ore is processed in a run-of-mine heap leach facility. In 2011, Kinross completed the construction of the West Branch dump leach and ADR (Adsorption, Desorption and Refining) facilities, the initial phase of the project expansion at Tasiast.

On March 31, 2014 Kinross announced results of its feasibility study for the Tasiast expansion project. The study, based on an optimal mill size of 38,000 tonnes per day, produced promising results that indicate the potential to significantly increase cash flow per share, enhance the Company's production profile, and lower costs.
