VANCOUVER, March 28 /CNW/ - Pinnacle Mines Ltd. and Mountain Boy Minerals Ltd. announce that the 2006 Silver Coin exploration program is scheduled to begin in May and will include geological mapping, trenching, geochemical surveys and drilling. The main objective of the program will be to add additional resources to those announced on March 15, 2006. The total inferred resource already contains an estimated 500,000 ounces of gold, and 2.11 million ounces of silver. The resource consists of 11.3 million tonnes grading 1.60 g/t Au, 6.64 g/t Ag, 0.06% Cu, 0.19% Pb, and 0.41% Zn and has been calculated in accordance with CIMM (2000) standards, at a zero cutoff by Minefill Services, Inc. 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 program is designed to expand the known surface limits of the Main Breccia mineralization both to the north and south along strike, test the Main Breccia at depth and test the Perseverance zone through drilling. The program which will total at least 15,000 meters of drilling will utilize at least 2 drills through the field program. Initially one drill will test the south extension of the Dan zone both along strike and at depth. A second drill that is capable of coring to a depth of at least 1000 meters, has been contracted from Britten Brothers Drilling of Smithers, BC and will commence drilling in early June. It will test the potential at depth along the Main Breccia zone, primarily to the south. 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.

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.
