Kinross acquired its 50% ownership interest in the Round Mountain gold mine and became the operator on January 31, 2003, upon completion of the merger with Echo Bay. An affiliate of Barrick Gold Corporation owns the remaining 50% interest in the joint venture, known as the Smoky Valley Common Operation.

Round Mountain is an open pit mining operation located in Nye County, Nevada. Most of the people who work at the mine live in the nearby communities of Hadley and Carvers.

Gold production in the Round Mountain district dates back to 1906. A hundred years later, Round Mountain mine reached the significant milestone of 10 million ounces poured, achieved over a 20-year period.

Round Mountain uses conventional open-pit mining methods and recovers gold using four independent processing operations. These include crushed ore leaching (reusable pad), run-of-mine ore leaching (dedicated pad), milling and the gravity concentration circuit. Most of the ore is heap leached, with higher grade oxidized ores crushed and placed on the reusable pad. Lower grade ore, ore removed from the reusable leach pad, and stockpiled ore that was previously leached are placed on the dedicated pad.
