Kinross acquired its ownership in the Chirano mine on September 17, 2010 upon completing its acquisition of Red Back Mining Inc.  Chirano is located in southwestern Ghana, approximately 100 kilometres southwest of Kumasi, Ghana's second largest city.  Chirano achieved its first gold pour in October 2005, and consists of 11 deposits: Akwaaba, Suraw, Akoti South, Akoti North, Akoti Extended, Paboase, Tano, Obra South, Obra, Sariehu and Mamnao.

The mine is within the Bibiani gold belt and the mining plan at the time of Kinross' acquisition of Red Back calls for the exploitation of 11 gold deposits spread along a strike length of approximately10 kilometres by both open pit and underground mining methods. The second underground mine at Paboase is now in production and Kinross plans to continue underground development in 2013.

Open pit and underground ore are processed at the Chirano plant. The capacity of the mill is approximately 3.5 million tonnes per annum. Processing involves crushing, ball mill grinding, leaching, and CIL. Gold is recovered by an elution circuit.
