Copper Mountain Mine:
The Copper Mountain Mine has an 18,000 acre land package with multiple prospective targets. In 2008, the company succeeded in finishing one of the largest drill programs in British Columbia (106,000 meters) and increased the resource estimate by 45% to 5 billion pounds of copper. The goal of the program was achieved when the results of drilling confirmed continuity of mineralization between the pits which allowed for the development concept of a new merged pit, known as the 'Super Pit'. This new Super Pit is still open to the north, southeast and northwest, as well at depth.

The aim of future exploration program is to define additional resources from numerous untested targets previously identified by a deep penetration Titan 24 survey that was conducted in late 2007. Interpretation of the geophysical properties is consistent with the geological model of hydrothermal alteration and mineralized zones within an alkali porphyry setting.

Summary of 2011 Exploration Program
The current years' exploration program has been limited due to funding constraints. The Company's primary development plan from the beginning was to get the property into production as quick as possible and then have operation cash flow fund for future exploration programs. After the mine has achieved its designed capacity on a consistent basis, the Company plans to implement a multi– year exploration program to further understand the potential of the deposit.
The current exploration program is focused on testing some peripheral titan 24 anomalies outside the current mine plan including Oriole, Virgina, and Voigt zones.
Review of 2010 Exploration Program
The 2010 Exploration program was designed to further enhance the mine plan economics by defining additional resources in the Oriole, Pit 3 deeps, Pit 2 and Saddle zone areas. Mineralization was encountered in all areas with encouraging results specifically below Pit 2. Further drilling i being proposed to follow up on successes from the 2010 program.
Geology & Mineralization
Copper Mountain is host to a large, structurally complex alkalic porphyry copper–gold–silver system that is part of a northerly trending Mesozoic tectonostratigraphic terrane termed Quesnellia. The terrane is composed of a volcanic arc with overlying sedimentary sequences, all of which were built on top of a deformed, oceanic sedimentary–volcanic complex. The principle rock formation of Quesnellia is the Late Triassic Nicola Group, a predominately subaqueous island–arc assemblage composed of volcanic and lesser sedimentary rocks. The Nicola Group rocks have a stratigraphic thickness of approximately 7.5 km and form a 25 km wide band that extends from the Canada‚Ä;ìU.S. border north to beyond Kamloops Lake. The Copper Mountain alkalic porphyry copper–gold camp occurs in the 'eastern volcanic belt' of the Nicola Group.
A stratigraphic sequence of volcanic and sedimentary rocks has not been defined for the Nicola Group within the Copper Mountain area, however, the Group includes:
- massive and rarely pillowed mafic and intermediate flows and flow breccia;
- coarse volcanic breccia with rounded clasts (agglomerate), sometimes containing hornblende–phyric monzodiorite clasts;
- felsic and intermediate water–lain tuff (greywacke) and lapilli–tuff;
- volcanic siltstone, sandstone, conglomerate and minor limestone.
These rocks are exposed in a north–westerly trending belt, approximately 1,100 m wide and 4,300 m long, sandwiched between various intrusive phases.
The majority of the copper–gold mineralization at Copper Mountain is in the form of veins, fracture fillings, and disseminations within volcanic rocks of the Nicola Group (Upper Triassic) and within intrusive rocks of the Lost Horse Suite (Lower Jurassic). Mineralization has strong continuity, in the vertical direction and dominant vein and fracture orientations vary with location.
As a broad simplification, mineralization at Copper Mountain consists of structurally controlled, multidirectional veins and vein stockworks. Mineralization has been subdivided into 4 types:
- disseminated and stockwork chalcopyrite, bornite, chalcocite and pyrite in altered Nicola LHIC rocks;
- hematite–magnetite–chalcopyrite replacements and/or veins;
- bornite–chalcocite– chalcopyrite associated with pegmatite type veins; and
- magnetite breccias
Each mineralization type can be found in all pit areas, but each pit is unique with respect to the relative quantities and character of mineralization type. The alteration that is associated with each mineralization type has some degree of variation as well. Each pit area also has distinctive Cu:Ag:Au ratios.
The figure below represents a schematic cross section model of mineralization at Copper Mountain, showing the relationships of the intrusions, structures and possible flow paths for hydrothermal fluids. A large variety of alternation types, commonly overlapping, occur throughout the Copper Mountain Camp.
