Deposit Type

  • Epithermal
  • Vein / narrow vein


Summary:

The mineralization was divided into the following domains, separated by north-northwest fault, for the purpose of resource modelling.

Bear Creek Hanging-Wall Vein System/Domain, bounded by Ripper Fault to south and Cabin Fault to north. The Hanging-Wall vein is comprised predominantly of massive white sulphide poor silica with typical low- sulfidation epithermal textures, including recrystallization, coliform and crustiform banding, adularia bands, amethyst, etc.

Bear Creek Footwall Vein System/Domain, bounded by Cabin Fault to south and Talapoosa (South) Fault to the north. The Footwall vein is more sulphide rich, associated with a number of gangue phases including, red hematitic silica, chlorite and minor white to clear silica.

Main Zone Vein System/Domain bounded by Talapoosa (South) Fault to the south and Opal/Dyke Fault to the north.

The mineralization at both Dyke Adit and East Hill shows similarities in appearance and texture to that of the Hanging-Wall Zone at Bear Creek.

The modelling of veins and their bounding faults indicates that the general trend of all mineralization is around 115°, with two prominent dip angles:

- Steeply-dipping veins at approximately 70° south, for the Hanging-Wall and Footwall Zones at Bear Creek and for the eastern-most portion of the Main Zone.

- Shallowly-dipping veins, at approximately 20 to 40° south for the Dyke Adit, northwest part of the Main Zone (north) ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mine design consists of three mining areas: the Main Pit, Dyke Adit, and the East Hill Pit. Under the current analysis, the Main Pit and Dyke Adit combine into one open pit instead of two separate pits. Approximately 90% of production is from the Main Pit area, with 7% from the Dyke Adit area, and the remaining 3% from the East Hill area.

The overall strip ratio is 1.47 units of waste to each unit of mineralized material production.

Waste rock storage areas will be located toward the northeast and southwest sides of the pit areas in as close proximity as possible to the mining areas so as to minimize waste haulage distances. These areas were sized to store a combined 90Mt of waste rock.

Industry standard surface mining techniques formed the basis of mine production. This Base Case Scenario used CAT 992 – 16.5 yd3 wheel loaders and CAT 777 100st trucks as production prime movers.
