Yellowhead Mining Inc. (TSX VENTURE:YMI) has reported the results from the first drill hole of an ongoing 4,000 meter (8 hole) diamond drilling program designed to expand the current open pit resources, which is expected to be completed mid-January 2011.
This program is being managed by CME Consultants Inc. ("CME").
Drill hole HC10-76 is part of a three-drill-hole fence through the western part of the deposit designed to test depths below the historical drill holes of the early 1970's. The drill hole location is shown on the attached plan map. The drill hole intersected numerous intervals of significant copper mineralization which can be grouped into four principal copper horizons.
The top horizon in-filled and proved the continuity of the mineralization within the current proposed pit outline. The horizon includes multiple copper zones including 0.49% Cu over 27.20m, and 0.35% Cu over 33.13m. Numerous high grade intervals over shorter intervals will add to the overall resource at a 0.15% Cu cutoff.
The remaining three copper horizons extend mineralization below the current pit limits in excess of 125 meters. These zones include broad intervals such as 0.44% Cu over 24.08m and narrower, higher grade material of 1.42% over 7.00m (or approximately 0.66%Cu over a 15m bench height).
Harper Creek is a copper-gold-silver volcanogenic sulphide deposit with an indicated resource of 4,000,000,000 pounds of copper and inferred resource of 500,000,000 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 volcanic and sedimentary rocks.
Ian Smith, Chief Executive Officer, stated "The results for hole HC10-76 demonstrate the potential to increase the resource within the established resource surface outline, by drilling deeper than the historical drilling from the 1960's and 1970's."
