Exhibit 99

Press release issued February 20, 2007 in which the Registrant announced that a National Instrument 43-101 compliant study of its Mitchell gold-copper discovery has confirmed a major new resource which may have significant expansion potential. The study by Resource Modeling Inc. (“RMI”) of Tucson, Arizona will be filed on SEDAR within 45 days. The Mitchell porphyry is located on the Registrant’s 100% owned Kerr-Sulphurets project near Stewart, British Columbia. At Mitchell, RMI estimates an Inferred Mineral Resource of 564 million tonnes grading 0.72 grams per tonne gold (13.1 million ounces) and 0.18% copper (2.23 billion pounds) at an equivalent gold cut-off grade of 0.50 grams per tonne gold. Equivalent grades were determined using a gold price of US$475 per ounce and a copper price of US$1.50 per pound. The deposit is currently defined by diamond core holes that were drilled on approximately 200-meter centers. The estimate of Mineral Resources is based on 9,530 meters of core drilling, including 23 holes (7,476 meters) drilled by the Registrant at Mitchell during 2006.
