About Yellowhead Mining Inc. and the Harper Creek Project

The Harper Creek Project is a copper-gold-silver volcanogenic sulphide deposit with a measured and indicated resource of 563.2 million tonnes grading 0.31% Cu (3.6 billion pounds of copper) plus 0.032 g/t gold and 1.08 g/t silver, plus an Inferred Resource of 117 million tonnes grading 0.29% Cu (0.7 billion pounds of copper). The Harper Creek Project is located in south-central British Columbia, approximately 150 kilometers by highway north of Kamloops.

Yellowhead has a 100% interest in the Harper Creek development project*. A Preliminary Economic Assessment Report (``PEA``), which demonstrated the technical and economic viability of the Harper Creek Project, was completed at the end of March and filed on SEDAR on April 1, 2011 and can be viewed on www.sedar.com. The PEA demonstrated a 22 year project life at a milling rate of 70,000 tonnes per day, a planned production of 149 million lbs. copper in concentrate per annum for years one to eight, (132Mlb/y LOM), a life-of-mine stripping ratio 0.88:1, an IRR of 19.8% with a base case copper price of US$2.66/lb., an NPV8 of US$598 million and a capital cost of C$759 million in Q4 2010 dollars, including contingency with a 4 year payback. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

* (Subject to the payment of a 3% NSR royalty capped at $2.5 million, adjusted for inflation and an additional 2.5% NSR royalty on an estimated 3.3 million tonnes of ore which is expected to be mined beginning in year nine within the NI 43-101 resource.)
