VANCOUVER, Dec. 5 /CNW/ - Pinnacle Mines Ltd. and Mountain Boy Minerals Ltd. announce gold-silver assays from drill holes testing the south extension of the Main Breccia Zone on the Silver Coin property near Stewart, BC. The most recent results from drill holes DDH-2005-65 through 79 continue to extend the mineralization of the Main Breccia Zone. All reported drill holes DDH-2005-65, DDH-2005-66 and DDH-2005-72 to 79 are within the Kansas claim located along the south end of the known Main Breccia Zone.

<< Results for the drilling are shown below:

DDH-2005-65 (azimuth 083 degrees and -60 degree dip) and 66 (azimuth 083 degrees and -60 degree dip) were drilled 96 meters north of previously reported DDH - 2005-69 and 70. Drill holes DDH-2005-71 to 74 were drilled off the same set-up, 41 meters north of DDH-2005-69 and 70. DDH-2005-74 was drilled at an azimuth of 263 degrees and a dip of -45 degrees. DDH-2005-71 (-70 degrees), DDH-2005-72 (-80 degree dip) and DDH-2005-73 (- 60 degree dip) were drilled at an azimuth of 083 degrees. DDH-2005-75 to 79 were drilled off the same set-up, 63 meters north of DDH-2005-69-70. DDH-2005-75 (-60 degree dip) and DDH-2005-76 (-70 degree dip) were drilled at an azimuth of 083 degrees. DDH-2005-77 (-50 degree dip), DDH-2005-78 (-60 degree dip) and DDH-2005-79 were drilled at an azimuth of 263 degrees. Based on the 2005 exploration program, the overall strike length of the mineralization as indicated by trenching and drilling is defined along 2000 meters, a vertical height of 700 meters and widths varying from 10 to 100 meters. The Main Breccia Zone mineralization is typified by an early stage of pervasive sericite-pyrite-quartz alteration; a main stage of quartz stockworks, breccias and silicification carrying gold associated with disseminated pyrite, sphalerite, galena and chalcopyrite; and a late stage of semi-massive sulphide pods carrying significant base metal values. Mineralization at Silver Coin is consistent with the two main types of mineralization at the nearby, former producing Silbak-Premier mine which produced 4.7 million tons that yielded approximately 1.8 million ounces gold, 41 million ounces silver, 4.2 million pounds copper, 62 million pounds lead and 20 million pounds zinc. The Silver Coin property is strategically situated 24 kilometers north of Stewart on the Granduc road. The infrastructure in the area is excellent with good roads, power and water. Assay results from drill holes are released when received from Assayers Canada and the assay data has been through internal validation of quality assurance and quality control. Pinnacle Mines has established a sampling and assay control program with blind insertion of assay standards; noting that there is also an internal quality control and quality assurance program in place at Assayers Canada that includes blanks, duplicates and standards. E. Kruchkowski, P. Geo., a qualified person under National Instrument 43-101, is in charge of the exploration programs on behalf of the Companies. Drill core and trench samples are assayed by Assayers Canada of Vancouver, BC. Pursuant to an option and joint venture agreement, Pinnacle and partner Mountain Boy Minerals can earn up to a 60% interest of Tenajon's 100% owned Kansas property by spending $1.0 million on exploration and development over a 4 year period. In addition, the partnership has the right to earn an additional 10% in Kansas by bringing it through a positive feasibility study within 4 years of earning its 60% interest. The Kansas property is a crown grant claim, 19.5 hectares in size, and is surrounded by the Company's Silver Coin land holdings.

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, porphyry molybdenum in the Stewart and McKenzie areas and copper-nickel-platinum group metals in the McKenzie area.
