Deposit Type

  • Vein / narrow vein
  • Volcanic hosted
  • Epithermal


Summary:

The Round Mountain Gold deposit is a very large, epithermal, low-sulfidation, volcanic-hosted, hot-springs type, precious metal deposit, interpreted to be located along the margin of a buried volcanic caldera. The deposit genesis is intimately associated with the Tertiary volcanism and caldera formation. Intracaldera collapse features and sympathetic faulting in the metasedimentary rocks provided the major structural conduits for gold-bearing hydrothermal fluids. In the volcanic units, these ascending fluids deposited gold along a broad westnorthwest trend.

Gold mineralization within the Round Mountain deposit occurs as electrum in association with quartz, adularia, pyrite and iron oxides. Shear zone fractures, veins and disseminations within the more permeable units (typically open pumice sites) host the mineralization. Primary sulfide mineralization consists of electrum associated with or internal to pyrite grains. In oxidized zones, gold occurs as electrum associated with iron oxides, or as disseminations along fractures.

Alteration of the volcanic units within the Round Mountain deposit can be characterized as a continuum from fresh rock progressing through chlorite, clay, sericitic+quartz, adularia+quartz+sericite, and quartz+adularia alteration assemblages. The alteration is zoned outward from potassic at the center to propylitic on the margin. There is a reasonable correlation between increasing gold grades and increasing degrees of alteration. ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

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.

Waste material is hauled to existing waste rock dumps, or placed in the proposed optional in-pit waste rock dump. Ore material is either ........
