STEWART, BC, Oct. 15 /PRNewswire-FirstCall/ - Mountain Boy Minerals Ltd and Pinnacle Mines Ltd announce that further assays have been received from the 2008 drill program on the Silver Coin project. A total of approximately 12,600 meters of drilling was completed in 79 holes on the Kansas and Big Missouri claims. Drilling tested in areas with little or no drilling in order to provide data for an updated resource calculation. Two different zones were tested with the drilling including the BM massive sulphide zone as well as the Main Breccia zone. The BM zone has had limited drilling completed on it to date. Results of the drilling indicate that the Main Breccia zone extends northwest across the Big Missouri claim as well as trending south across the Kansas claim on to the Idaho claim. Strike length of this breccia zone appears to be in excess of 1.5 kilometers. DDH-282 tested the Main Breccia zone while DDH-301A tested extensions of the BM mineralization consisting of strong sulphide mineralization including sphalerite, galena and chalcopyrite Assays received for DDH-282 and DDH-301A are listed in the table below. ------------------------------------------------------------------------- From To Width Au Ag Cu Pb Zn DDH (m) (m) (m) g/t g/t % % % CLAIM TESTED ------------------------------------------------------------------------- ------------------------------------------------------------------------- 2008-282 135.64 181.86 45.72 8.86 70.81 0.025 0.14 0.35 Kansas ------------------------------------------------------------------------- including 142.95 144.78 1.83 58.66 278.1 0.165 1.17 3.25 Kansas ------------------------------------------------------------------------- and 160.02 166.12 6.10 31.51 391.70 0.02 0.21 0.46 Kansas ------------------------------------------------------------------------- ------------------------------------------------------------------------- 2008-301A 14.33 90.53 76.2 1.15 51.18 0.41 0.14 3.89 Big Missouri ------------------------------------------------------------------------- including 24.99 64.62 39.62 1.34 66.11 0.58 0.21 5.31 Big Missouri ------------------------------------------------------------------------- including 69.19 78.33 9.14 1.16 84.85 0.56 0.11 6.58 Big Missouri ------------------------------------------------------------------------- The Silver Coin is a gold-silver-base metal property located about 24 kilometers north of Stewart, British Columbia in the Skeena Mining Division. The Silver Coin project and associated minerals claims is a 51-49% joint venture between Pinnacle Mines and Mountain Boy Minerals except for the Kansas claim which is 29 % mountain Boy and 71 % Pinnacle. A NI 43-101 report dated May 1, 2007 indicates that the property has 488,202 gold equivalent (Au-Ag) ounces in the measured and indicated category as well as 1,000,499 gold equivalent ounces in the inferred category. The 2008 drill program is designed to add precious metal resources and to improve the resource categories already established in the 43-101 compliant resource calculation and technical report. Studies being completed during 2008 include metallurgical work to establish possible recoveries as well as acid generation. Alex Walus P. Geo. is the qualified person looking after the drill program on behalf of the companies. Drill core samples are assayed by Assayers Canada of Vancouver, BC. Mountain Boy Minerals Ltd is a Canadian based mineral exploration company whose activities are in the Stewart and McKenzie area of BC. It is actively exploring for gold-silver-base metals on the Silver Coin project, silver-base metals on their American Creek properties, copper-gold in the Stewart area, porphyry molybdenum in the Stewart and McKenzie areas and copper-nickel-platinum group metals in the McKenzie area.
