West Kirkland Mining Inc. (TSX VENTURE:WKM) report that a NI 43-101 compliant inferred mineral resource estimate has been completed for the TUG deposit located in Utah, along the Long Canyon Trend. Using a cut-off grade of 0.1 grams per tonne gold, the TUG deposit is estimated to contain an inferred mineral resource of 679,000 gold equivalent ("AuEq") ounces as detailed below. The Company expects that a NI 43-101 report will be filed on SEDAR within 45 days.

---------------------------------------------------------------------------- Grade Grade Grade(2) Quantity Au Ag AuEq Ounces Ounces Ounces(2) Area Category (tonnes)(1) g/t g/t g/t Au Ag AuEq ---------------------------------------------------------------------------- TUG Inferred 27,110,000 0.49 15.8 0.78 431,400 13,844,800 679,000 ---------------------------------------------------------------------------- (1) Reported at a cut-off grade of 0.1 g/t Au. Mineral resources that are not mineral reserves do not have demonstrated economic viability. (2)AuEq was calculated assuming 100% metal recovery using a metal price ratio between Ag and Au (Ag:Au)= 0.018 (AuEq= Au+(Ag(i)0.018))
West Kirkland has the right to earn a 60% interest at TUG as part of a regional transaction completed in December 2010 with Fronteer Development (USA) Inc. (now a subsidiary of Newmont Mining Corporation). The TUG resource is primarily a near surface oxide resource that may be amenable to open pit mining and heap leach extraction for gold and silver. Approximately 34% of the tonnes of the resource, representing 44% of the AuEq ounces, are located within 40 meters of surface, providing potential for very low stripping and mining costs as well as short project lead times.
