February 17, 2010 Mustang Minerals Corp. Makwa Nickel Project Update TORONTO, ONTARIO--(Marketwire - Feb. 17, 2010) - The Board of Directors of Mustang Minerals Corp. (TSX VENTURE:MUM)(FRANKFURT:NJF) is pleased to announce the results of an updated Mineral Reserve estimate for the Makwa Nickel Project located in southeast Manitoba. The reserve update was completed by Micon International Limited (Micon). Highlights of the updated Mineral Reserve include increased project tonnage and contained metal. An updated project economics model estimates Nickel cash costs at US$3.91 per pound and US$2.70 including by-product credits. Mustang also is reviewing the potential to significantly increase metal production from the Makwa Project by including feed from its Mayville Cu-Ni Resource. The updated reserve is based on the October 14, 2009 resource model and estimate completed by Micon and announced in the press release of October 26, 2009. Recently completed geotechnical studies provided optimum pit slope design and an open pit mine design with production schedule was completed by Micon as an update to the mine design contained in the 2008 Prefeasibility Study ( see Mustang Press Release dated May 8, 2008). Whittle software was used to develop the economic open pit outline, based on cost and economic parameters developed in the Prefeasibility Study and metal prices stated below. The Updated Mineral Reserve Estimate as of February 05, 2010 is as follows: ------------------------------------------------------------------------ Reserve Tonnes Nickel Copper Platinum Palladium Contained Contained category (000) % % g/t g/t Nickel oz Platinum (tonnes) + Palladium ------------------------------------------------------------------------ Proven - - - - - - - ------------------------------------------------------------------------ Probable 9,855 0.541 0.113 0.094 0.339 53,276 137,194 ------------------------------------------------------------------------ Total 9,855 0.541 0.113 0.094 0.339 53,276 137,194 ------------------------------------------------------------------------ g/t equals gram/tonne 1. Metal prices ($US) used for the mine design were- Nickel $8.00/lb, Copper $2.20/lb, Cobalt $20.00/lb, Platinum $1500.00/oz and Palladium $350.00/oz, and a $CAD:$US exchange rate of 0.90. 2. Unit operating costs were as developed in the Prefeasibility Study. 3. Metal recoveries to concentrate and concentrate grade values were updated from the values used in the Prefeasibility Study as a result of 2009 metallurgical testing. 4. The average Net Smelter Return value of the reserve material is calculated as CAD$60.21 of which nickel contributes 87%, copper 7%, cobalt 2%, platinum 1% and palladium 3%. 5. The reserve estimated above includes allowances for dilution and mining losses. Economic viability of the mineralization was demonstrated by a discounted cash flow model, developed by Micon for the project, with a production rate of 1 million tonnes per year, a project operating life of 9.8 years and with preproduction capital costs and operating costs as developed in the Prefeasibility Study. Metal prices and exchange rate were as noted above in point 1 above except for copper for which a price of $US 3.00/lb was used. Sustaining capital costs were adjusted from the Prefeasibility Study values to account for the longer projected mine life. The cash flow model indicates a positive net present value after tax at a discount rate of 7% and Micon concluded that this demonstrates the reserve designation of the mineralization. Increased Metal and PGM from Previous Mineral Reserve Compared with the 2008 Reserve estimate, this December 31, 2009 estimate represents an increase in contained metals of over 17Mlb (17%) nickel, 4Mlb (21%) copper and 29,000 oz (28%) of platinum plus palladium. The approximate equivalent percentage increases are shown in parentheses. From the cash flow model, the life-of-mine cash cost of nickel production is $US 3.81 and with by-product credits is $US 2.70. Project Upside with Mayville Resource The Company sees significant upside to the Makwa project through the addition of additional resource to further amortize capital costs associated with the project. Mustang is currently evaluating the potential of sourcing additional mill feed from Mustangs Mayville Cu-Ni Property which is located approximately 35 km by road from Makwa. The Company is evaluating the potential for a higher grade core to the current estimated resource at Mayville (stated below) which would positively impact and provide significant upside to the overall project economics. Mayville Property M2 Zone Mineral Resource Estimate- January 2007- Scott Wilson RPA ------------------------------------------------------------------ Category Tonnage Nickel Copper Nickel Copper Tonnes % % pounds pounds ------------------------------------------------------------------ Indicated 21,947,000 0.20 0.48 94,261,000 232,023,000 ------------------------------------------------------------------ Inferred 1,851,000 0.20 0.43 8,109,000 17,584,000 ------------------------------------------------------------------ Resources that are not reserves do not have demonstrated economic viability.
