Yellowhead Mining Inc.: Harper Creek Drill Hole HC10-80 Confirms Mineralization Beyond Eastern Limit of Drill Holes in 2010 Resource Model

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 22, 2011) -

NOT FOR DISSEMINATION IN THE UNITED STATES OF AMERICA

Yellowhead Mining Inc. (TSX VENTURE:YMI) is pleased to report the results from the fifth and sixth drill holes of the on-going winter drill program. These holes, HC10-80 and HC10-81 are part of a four-hole fence (including HC10-79 reported on February 2, 2011) near the eastern limit of the resource on Section 305620E. Drilling on this fence was designed to test the eastern limit of the resource model (North and South zones) and continuity of the mineralization along strike to the east, as well as up-and-down dip extensions. Section 305620E ranges from 40 to 120 metres east of the most easterly drill holes (69-H-26, J-11, 96-1 and 96-7) that were used in the resource calculation.

Hole HC10-80 tested the down dip extension of the North zone mineralization intersected in hole HC10-79. The drill hole was collared approximately 300 metres to the north of drill hole HC10-79 and drilled to a depth of 480.67 metres. Hole HC10-81 tested the eastern extension of the South zone to a depth of 325.22 metres.

The significant intersection from Hole HC10-80 is presented in the table below.

Significant intersection - 0.2% Cu

No significant intersections were returned from Hole HC10-81.

The results of drill hole HC10-80 demonstrates the potential to extend the North zone both down dip and along strike to the east. Current drilling (holes 82 to 85) has targeted the down dip extension of the North zone. Hole HC11-85 (in progress) has been collared approximately 500 metres to the north of hole HC10-80. Future drilling is planned to test both the up-dip and eastern strike potential of holes HC10-79 and –80.

Laboratory assays lag the drilling and logging by approximately six weeks. The program is being managed by CME Consultants Inc. ("CME").

Ian Smith, Chief Executive Officer, stated "The results for hole HC10-80 confirms continuity of mineralization within the 2010 NI43-101 Resource pit at the eastern limits of that resource and demonstrates the potential to increase the resource along strike to the east and down-dip to the north. This is strongly supported by the results of extensive aeromagnetic and geochemical surveys and surface mapping and sampling of outcropping sulphides which identify drill targets extending some 3.0km to the east of the current eastern pit limit.

Harper Creek is a copper-gold-silver volcanogenic sulphide deposit with an indicated resource of 569 million tonnes grading 0.32% Cu (4,010,000,000 pounds of copper), plus an inferred resource of 62.7 million tonnes grading 0.33% Cu (460,000,000 pounds of copper) plus as yet an unquantified resource of gold and silver. Mineralization occurs as a series of tabular bodies hosted within the Eagle Bay Assemblage met-volcanic and met-sedimentary rocks.

QUALIFIED PERSON
Christopher O. Naas, P.Geo. B.Sc., Project Manager for Yellowhead's Harper Creek Project, is a qualified person as defined by National Instrument 43-101 and prepared or reviewed the preparation of the scientific and technical information in this press release with respect to the assay results from the Harper Creek drill program.

SAMPLE COLLECTION, ANALYSES, AND QA-QC
All core processing was undertaken by CME personnel. Core was cut by electric motorized rock saw with half core shipped to Eco Tech Laboratory Limited, part of the Stewart Group (Eco Tech), in Kamloops, BC for sample preparation and analysis. Drill core samples were analyzed for gold by fire assay with an AA finish and multi-elements by total digestion ICP-ES. Core samples returning greater than 2,000 ppm copper in the ICP-ES process were then assayed for copper. In addition to control samples inserted by CME, the analytical laboratory routinely inserted their own control samples, which consisted of standards, blanks and sample repeats.

ABOUT YELLOWHEAD MINING INC.
Yellowhead has a 100% interest in the Harper Creek Project subject to the payment of a royalty capped at $2.5 million, adjusted for inflation, on claims within the NI 43-101 resource. The Harper Creek Project is a large copper-gold-silver project located in south-central British Colombia, approximately 150 kilometers by highway from Kamloops.
