Update on Tantalum and Niobium Exploration at Project in British Columbia

  1. 1. Commerce Resources Corp. Completes 2011 Exploration Program at Upper Fir Tantalum and Niobium Deposit, Blue River, British ColumbiaHighlights:  2011 fieldwork included approximately 8,715 metres in a 34 drill-hole definition drilling program which was targeted to improve understanding of geological and structural relationships within the Upper Fir deposit.  2010 drilling results (54 holes; 12,949 metres) are currently being compiled for inclusion in an updated three dimensional block model and resource estimate which will itself form a separate resource update anticipated by second quarter 2012.  Results of exploration to the end of 2010 will be described in a technical report currently in preparation under the direction of AMEC which will provide the next milestone in the evaluation of the Upper Fir deposit.  Assay results from the 2011 holes remain outstanding and will be compiled for inclusion into a separate resource update.November 18, 2011 - Commerce Resources Corp. (TSXv: CCE, FSE: D7H) (the "Company")is pleased to provide an update on its recently completed exploration and development activitiesfor the Company’s wholly owned Blue River Project, east-central British Columbia. The BlueRiver Property is host to the Upper Fir Tantalum and Niobium Deposit, which was discovered in2002, and which has been the principal focus of the Company’s work in British Columbia since2005.Exploration in 2011 included 8,715m of HQ-diameter diamond drilling in 34 holes largely forpurposes of infilling geological and structural information within the Upper Fir deposit.Additional field work included core logging, assaying, down-hole geophysics, specific gravitymeasurements and comprehensive re-logging of core from previous years, as well as geologicaland structural mapping to test the evolving structural model. Incoming results will be compiledfor eventual inclusion into an updated resource model.On November 3, 2011, the Company announced completion of a positive National Instrument43-101 compliant Preliminary Economic Assessment (“PEA”) for the Upper Fir Tantalum-Niobium Deposit. The PEA prepared by independent consultants, AMEC Americas Limited(AMEC), indicates that the deposit can be developed economically as an underground mine andrecommends further studies to support a pre-feasibility level assessment of the project. AMEC isa leading international consulting, engineering and project management company. A technical
  2. 2. report by AMEC entitled Preliminary Economic Assessment Blue River Tantalum-Niobiumproject dated September 29, 2011, and announced on November 3, 2011, is available athttp://www.sedar.com.The economic evaluation of the PEA is based on a mineral resource estimate with the effectivedate of September 29, 2011, which incorporates drilling and structural data developed from theproject to the end of 2010, including detailed solids modeling and preliminary metallurgical andprocess flow sheet designs, but is based only on assay data to the end of 2009 drilling totaling183 holes comprising 37,446 metres of HQ drill core.The table below summarizes drilling completed in prior years:Summary of Upper Fir Drilling 2009-2011 Year Core Metres Holes Comments Drilled Size Drilled2005 -2009 HQ 37,446 183 Basis for resource used in PEA Assays in hand: Basis for resource update 2010 HQ 12,949 54 estimated 2Q 2012 Assays pending: Basis for subsequent 2011 HQ 8,715 34 resource update (post 2Q 2012)Drilling completed in 2011 should be considered largely as infill within the Upper Fir Depositbut also explored known extensions of the deposit at its north end. The infill drilling wasdesigned to determine geological and structural relationships, and improve understanding of theresources previously announced on February 2, 2011, which considered only drilling to the endof 2009. As recommended by AMEC, the 2011 exploration was also completed in anticipationof pre-feasibility requirements.An updated block model and resource estimate with accompanying technical report under thesupervision of AMEC is currently underway using mapping and drill data from the 2010campaign.To avoid an undue delaying in completing this resource update while the assays and other datafrom 2011 are being processed, the new data from 2011 are to be included in a second andsubsequent technical report which provides a second upcoming milestone for the Blue RiverProject. Work on this technical report will begin as soon as results are received.
  3. 3. Other Work Completed and Ongoing in 2011Metallurgical test work including the engineering for pilot plant design is being coordinated byAcme Metallurgical with a view to optimizing the process design used in the PEA.Environmental baseline investigations, including water quality, hydrology and vegetationstudies, which commenced in 2006, are continuing; contributing to the ongoing environmentalassessment. Additional geotechnical engineering is also underway.The Blue River Project is wholly owned by Commerce and encompasses 105,373 hectares (about1,050 km2). Power transmission lines, rail, and paved and gravel roads are all adjacent or withinthe property boundaries. Transalta Corp.s 18 MW Bone Creek run-of-river hydroelectricityproject was recently completed near the project and began production in April 2011.The Upper Fir deposit is one of over 25 carbonatite occurrences on the project. Indicated mineralresources total 36.35 million tonnes containing 195 ppm Ta2O5 and 1,700 ppm Nb2O5 andInferred mineral resources total 6.40 million tonnes containing 199 ppm Ta2O5 and 1,890 ppmNb2O5. The mineral resource estimate is supported by a base case price assumption ofUS$317/kg Ta metal in an oxide product and $US46/kg niobium metal in an oxide product.Sufficient working capital is available to complete all of the Company’s development andexploration plans for Blue River.New Appointment to Board of DirectorsCommerce Resources is pleased to announce the appointment of Jenna Hardy to the Board ofDirectors. Jenna Hardy, M.Sc, MBA, P.Geo. has over 25 years of exploration and miningindustry experience in Canada, United States, Mexico and South America, and was involved inre-opening, greening and expansion of large-scale historic operations at Quiruvilca and HuaronMines in Peru and at the Cozamin and La Colorada Mines in Mexico. From 1996 to 2004, sheserved as the Manager of Health Safety Environment with Pan American Silver Corp.(NASDAQ: PAAS, TSX: PAA) where she was responsible for corporate oversight of health,safety and environmental issues at operating subsidiaries in Peru, Mexico and Bolivia, as well asdevelopment projects in Argentina, Canada and the USA.
