The principal area of mineralization on the project is the Yellowhead Copper Deposit (the Deposit). The northeast trending Harper Creek Fault separates the deposit into a west domain and an east domain. In the west domain, chalcopyrite mineralization is primarily in three copper bearing horizons. The upper horizon ranges from 60 m to 170 m in width and is continuous along an east-west strike for some 1,300 m, dipping approximately 30º north. Mineralization within this horizon occurs within felsic and mafic volcanics and volcaniclastic rock units. The middle horizon is not as well developed and is often fragmented. It primarily exists within a graphitic and variably silicified package of rocks that range from 30 m to 40 m in width at the western extent, increasing up to 90 m locally eastward, gradually appearing to blend into the upper horizon. Of the three horizons, this contains strong to intense silicification and localized tension fractures filled with mineralization. The lowest or third horizon has less definition mainly due to a lack of drill intersections. Commonly hosted within mafic to intermediate volcaniclastics and fragmental rocks, it can range from 30 m to 90 m in width although typical intersections are in the 30 m range. These horizons host within felsic and mafic metavolcanics and metavolcaniclastics and generally contain foliation-parallel wisps and bands as the dominant style of sulphide mineralization.

Location and Infrastructure
The Yellowhead project is located approximately 150 km northeast of Kamloops and consists of 131 mineral claims covering 42,500 hectares.

The Yellowhead Development Plan 1 envisions an open pit mine utilizing conventional truck and shovel mining techniques. The equipment utilized in this operation would be typical of that found in today’s large open pit operations. Open pit operations are planned to supply a conventional copper concentrator with 90,000 tpd of ore at a cutoff grade of 0.17% copper. Ore would be delivered to a primary crusher located at the southwestern rim of the ultimate pit. An ore stockpile would be built during the first five years of operation to maximize ore grade delivered to the mill during that period and provide an operating contingency. Potentially acid generating (PAG) waste rock would be stockpiled inside the tailings storage facility while non-acid generating (NAG) waste and overburden would be stockpiled in conventional waste storage locations proximal to the open pit.

The pit design is based on the selected Lerchs-Grossmann pit shell. A single-bench configuration of 15 m high benches is used based on the scale of mining equipment selected. Steeper inter-ramp slopes up to 150 m high are used with enlarged berms or haul roads breaking up larger slopes to honor overall slope requirements. Haul roads are designed 40 m wide to allow for double-lane hauling including allowances for berms and dit ........

The proposed process plant for the Yellowhead ore is a conventional sulphide concentrator utilizing three stages of comminution, three stages of flotation and concentrate dewatering. The concentrator has been designed for simplicity of operations and maintenance and to meet the project metallurgical targets.

Flotation and Regrinding Circuits
The ground ore from both grinding lines would be combined and processed in the flotation and regrind circuits to recover the valuable minerals. The recovery process would consist of rougher flotation, concentrate regrind, and two stages of cleaner flotation.

The rougher flotation circuit is designed with a single bank of forced air flotation tank cells fed the cyclone overflow product from both primary grinding lines. The rougher flotation circuit would produce a concentrate which would be pumped to the regrind circuit and a tailing stream which would gravity flow to the TSF. Flotation reagents added to the rougher flotat ........
