 Yellowhead Mining is a private Canadian company with a 100% interest in the Harper Creek copper-gold-silver advanced exploration project in south-central British Columbia, approximately 90 kilometres from Kamloops. Harper Creek offers exceptional potential as the largest, most advanced green-field volcanogenic sulphide project in British Columbia and one of the largest copper pre-development projects in Canada.
HARPER CREEK PROJECT HIGHLIGHTS
- NI 43-101 Indicated resource of 538.4 million tonnes grading 0.32% copper and Inferred resource of 64.7 million tonnes grading 0.34% copper, containing 3.8 billion pounds and 0.5 billion pounds of copper respectively, at a 0.2% copper cut-off.
- Pit-optimized resource of 420 million tonnes grading 0.30% copper, with 2.77 billion pounds contained copper plus unquantified gold and silver, based on a 0.2% copper cut-off with stockpiled and blended 0.15 -- 0.2% copper.
- Based on 50,000 tonnes/day milling, this represents a 23 mine life.
- Stripping ratio 1.0:1 life of mine; 0.62:1 for the first 3 years.
- At a copper price of $3.00 per pound, the investment would be paid back in less than two years
- A Preliminary Economic Assessment completed in April 2008 shows cash mine-site operating cost of $1.02/lb copper for the first 3 years, and $1.38/lb over the life of mine at 50,000 tonnes/day
- Harper Creek is located adjacent to rail, highway, power, water and town-sites.
- Ongoing metallurgical testing of samples resulted in a cleaner-stage concentrates grading 28.8% - 30.9% copper with recoveries ranging from 86.8% to 88%, plus gold and silver in concentrate ranging from 1.6 -- 4.8 g/t gold and 91.5 -- 106.9 g/t silver. The tests were run on material with head grades of 0.35% copper and 0.75% copper. Deleterious elements in ore and concentrates are well below levels that would attract penalties.
- Drilling data over 54,000 metres, including 29,701 metres on the deposit by Noranda and US Steel in the 1960's and 1970's and a junior exploration company in 1996, and over 25,000 metres by Yellowhead in 2006 - 2008.
- Mineralized envelope greater than 2.0 km along strike, over 2.0 km down dip, in a 1 kilometre thickness of volcano-sedimentary stratigraphy, and open in all dimensions
- A feasibility study is planned for 2008.
- Numerous exploration targets outside the known deposit envelope have been identified through airborne geophysics and soil geochemistry.
- Yellowhead Mining owns or controls mineral tenures of 38,902 hectares.
