Mine Life2030
In 2023, the Round Mountain exploration program will focus on supporting Phase X Underground development, geological modeling, and drilling.

Construction of the exploration decline at Phase X started in the first quarter and underground development is progressing to start definition drilling in early 2024. The Company is also advancing studies and permitting for a potential underground mine at Phase X in parallel with the underground development to advance our path to production.

The Company is continuing to mine Phase W (W1 and W2) while progressing underground opportunities. The open pit expansion opportunities at Phase W3 and Phase S remain in reserves and will continue to be optimized and evaluated for potential exploitation with sustained macroeconomic improvements.

Deposit Type

  • Vein / narrow vein
  • Volcanic hosted
  • Epithermal


Summary:

The mine operates two open pits in two distinct areas; the Round Mountain Pit (RMP) and the Gold Hill Pit (GHP). Round Mountain deposit 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 o ........


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 hau ........
