The 100% Kinross-owned Kettle River-Buckhorn properties are located in Ferry County in the State of Washington. The properties cover approximately 3,075 hectares through patented and unpatented mining claims and fee lands. Kinross acquired Kettle River through its acquisition of Echo Bay on January 31, 2003. At the time, the mine was undergoing care and maintenance. Kinross resumed operations on the Emanuel Creek deposit in December 2003, which was completed in November 2005.

The Buckhorn Mountain Project

In August 2006, Kinross acquired the Buckhorn gold deposit, located approximately 76 kilometres by road from Kinross' Kettle River gold milling facility. Originally conceived as an open pit mine, Buckhorn was redesigned and developed as an underground mine, and the Kettle River mill was refurbished to process the ore.

The primary mining method employed is cut and fill, with a target production rate of 900 tonnes per day. The Buckhorn mine ore is trucked 75 kilometers to the Kettle River Mill, which has a 1,800 tonne per day capacity.
