The Round Mountain mine is located approximately 90 kilometres north of Tonopah in Nye County,
Nevada.
The Round Mountain mine currently operates a conventional open pit that is approximately 11,000 feet long in the north-west, south-east direction and 8,800 feet wide. The operation uses conventional openpit mining methods and recovers gold using three independent processing operations.
The Gold Hill mine is a small deposit located near the Round Mountain mine. Gold Hill is approximately 3,000 feet long in the east-west direction and up to 2,600 feet in the north-south direction. The mine is operated as an independent operation also using conventional open-pit mining methods. The ore consists of oxide material that is placed directly on a dedicated heap leach pad. Gold Hill is currently expected to end in 2023.
The mining is conducted on 35-foot to 50-foot benches by electric or hydraulic shovels and supported by the mobile equipment. Mining is conducted on both single and double bench configurations. Bench face angles and bench width vary with rock type and pit orientation. Haul roads are designed for a maximum grade between 10 and 11 percent with widths designed at 90 to 140 feet for two-lane traffic.
All explosives are stored and used in accordance with MSHA and BATF regulations.
