Taseko Announces a 170% Resource Increase and Upgrade at Aley18:02 EDT Wednesday, March 28, 2012VANCOUVER, March 28, 2012 /CNW/ - Taseko (TSX: TKO; NYSE Amex: TGB) (the "Company") reports that the Aley Project resource has been upgraded to a Measured and Indicated Resource. At a 0.2% Nb2O5 cutoff, the Measured and Indicated Resource is 286 million tonnes with an average grade of 0.37% Nb2O5 plus 144 million tonnes of Inferred Resource with an average grade of 0.32% Nb2O5. This represents a total resource tonnage increase of 170% from the NI43-101 compliant Inferred Resource released in the September 2011 technical report.The combined Measured and Indicated Resource contains 739 million kilograms of Niobium. An additional 323 million kilograms of Niobium are contained in the Inferred Resource.The new resource estimate is based on drill data gathered from Taseko's 2011 drilling program, along with historical drill data.Russell Hallbauer, President and CEO of Taseko, commented, "Confirming a Measured and Indicated Resource provides additional confidence that the deposit will support a long life, low cost mine. The contained kilograms of niobium make Aley the largest undeveloped niobium project in the world, and we anticipate completing our metallurgical work and finalizing the feasibility study to allow for an early 2013 investment decision."The in-pit measured and indicated resource for the Central Zone of the Aley deposit is summarized in the table below:COG% Nb2O5Measured Indicated Measured & IndicatedTonnes(000's)% Nb2O5Tonnes(000's)% Nb2O5Tonnes(000's)% Nb2O50.10137,3730.36215,1450.31352,5180.330.15126,7690.38197,7670.33324,5360.350.20112,6510.41173,1690.35285,8200.370.2596,1830.44131,9990.39228,1820.410.3081,3770.47102,9660.42184,3430.45The 0.20% Nb2O5 cut-off assumes a niobium price of US$50/kilogram and a 50% process recovery rate. G & A, processing and ore mining costs were assumed to be US$30/tonne milled plus waste mining costs of US$2.00/tonne. A 45° pit wall slope was generated to constrain the resource within the block model.The Resource Estimate was prepared by GeoSim Services Inc. of Vancouver, Canada, utilizing analytical results from the 96 core holes drilled on the Central Zone to date. Assays were composited in 6 metre downhole intervals. Grades were not capped as there was no significant outlier population identified. Block grades were estimated by ordinary Kriging in three passes and constrained by geologic and structural domains.  Blocks were classified as 'Measured' if there were two composites from at least two drill holes within 50 m of the block centroid based on the anisotropic search parameters.  Blocks not meeting the criteria for 'Measured' were classified as 'Indicated' if there were two composites from at least two drill holes within 100m of the block centroid.  All other estimated blocks were classified as 'Inferred'.The resource estimate was prepared by Ronald G. Simpson, P.Geo., with GeoSim Services Inc., a Qualified Person independent of Taseko. The qualified person reviewed and approved the contents of this news release. The Company expects to file the 2012 Technical Report on SEDAR (www.sedar.com) within 10 days.Russell HallbauerPresident and CEONo regulatory authority has approved or disapproved of the information contained in this news release.CAUTION REGARDING FORWARD-LOOKING INFORMATION This document contains "forward-looking statements" that were based on Taseko's expectations, estimates and projections as of the dates as of which those statements were made.
