Deposit Type

  • Breccia pipe / Stockwork
  • Vein / narrow vein
  • Epithermal


Summary:

The Bell Mountain property is located within the Fairview Peak caldera, a small Miocene (~19.2 Ma) volcanic center comprised of a thick sequence of rhyolite-dacite flows, flow domes, and pyroclastic rocks. Epithermal low-sulfidation gold-silver mineralization is hosted by calcite and quartz-calcite veins and stockwork associated with pervasive silicification. Veins and hydrothermal alteration are controlled by east northeast trending near-vertical structures and west-northwest cross structures. The precious metal-bearing minerals are electrum, argentite/acanthite, and native silver. To date, four main bodies of gold-silver mineralization (Varga, Spurr, Sphinx and East Ridge) have been defined by drilling. The larger Spurr and Varga zones are situated along the principal NE structural trend (Varga-Spurr fault), the Sphinx zone is controlled by a WNW cross structure (Sphinx fault). The East Ridge zone is controlled by a NE striking structure. The East Ridge Deposit consists of a single east-northeast trending quartz-calcite vein which dips steeply to the south.

At the Bell Mountain deposit gold-silver mineralization is strongly structurally controlled. The primary control is an east-northeast trending (~070o) zone of faulting, named the Varga-Spurr fault, which can be traced for more than 6000 feet (1.8 km). The Varga-Spurr fault dips steeply to the south and has experienced normal and dextral displacement. It is offset slightly in a right lateral sense by a set of n ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mining operation is assumed to be a conventional open pit mine, with drill and blast rock breakage and truck and loader materials handling.

The mine production schedule was based on an average of 5,000 tons / day delivered to the crusher and then placed on the heap leach pad as crushed mineralized material. The pits will be mined sequentially beginning at the Spurr pit near the crusher and progressing easterly to the Varga, Sphinx and East Ridge pits. The production schedule was constrained to produce a constant feed of mineralized material to the crusher and conveyor (or truck) loading onto the heap leach pad. Some stockpiling of higher grade material may be required to balance the crusher feed rate.

Pit haulage ramps are designed to optimize fleet schedules and minimize waste mining. Haulage ramp design parameters:
- Ramp Width - Two Way Traffic - 70 ft;
- Ramp Grade - Two Way Traffic - 12 percent;
- Ramp Width - Single Lane Traffic - 30 ft;
- Ramp Grade - Single Lane Traffic - 12 to 14 percent.

Mining Schedule
A mining schedule was generated based on resources within the conceptual designed pit phases using the following parameters and guidelines:
• Contract mining operations, 5 days per week, one shift per day;
• Crushing operations 5 days per week, two shifts per day; one weekend maintenance shift
• Average total annual mineralized material production of approximately 1.5 million tons. Hydra ........
