Trading Symbol: TSX-MTB Frankfurt-M9U.F OTC-MBYMF STEWART, BC, March 3 /PRNewswire-FirstCall/ -- Mountain Boy Minerals Ltd. announces that it has received all the results for the drilling on the MB silver property. A total of 27 holes tested 4 different targets on the property. Highlights of the 2007 program include 2390 g/t silver over 2.44 meters in DDH-HG-19 and 818 g/t silver over 3.05 meters in DDH-HG-17. Assays greater than 100 g/t for this drilling are as follows: ------------------------------------------------------------------------- DDH No From To Width Ag Cu Pb Zn (m) (m) (m) g/t % % % ------------------------------------------------------------------------- 2007-6 0.61 1.83 1.22 256.8 0.053 0.06 0.14 ------------------------------------------------------------------------- ------------------------------------------------------------------------- 2007-7 132.63 139.63 7.01 281.7 0.03 0.28 0.52 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-3 12.20 14.33 2.13 234.5 0.222 2.57 5.51 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-4 11.89 14.33 2.44 328.0 0.30 1.09 3.18 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-13 3.66 6.71 3.05 408.8 0.08 0.33 0.35 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-17 2.13 5.18 3.05 818.0 0.141 0.46 0.44 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-18 2.13 8.23 6.1 315.0 0.06 0.065 0.14 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-19 3.09 8.54 5.49 1617.2 0.28 0.38 0.30 ------------------------------------------------------------------------- including 6.10 8.54 2.44 2390 0.307 0.55 0.26 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HG-20 4.33 6.71 2.38 308.07 0.09 0.11 0.17 ------------------------------------------------------------------------- DDH-2007-7 tested the Mann vein, DDH-2007-6 was designed to test the North vein and the HG drill holes were deigned to test the High Grade vein. The HG holes were drilled off a pad blasted out of a steep hillside, 15 meters north of the 2006 drilling. The 2006 drilling intersected 5.18 meters of 5258 g/t silver, 0.66 % copper, 0.05 % lead and 0.05 % zinc in DDH-2006-10 and 8.53 meters of 2260 g/t silver, 0.404 % copper, 0.48 % lead and 0.56 % zinc in DDH-2006-19. The 2007 drilling indicated that the High Grade vein trended up hill away and up dip from the drill site. The intersection on the Mann vein in DDH-2007-7 is 150 meters south of underground workings and indicates an extension into an area that has been untested in the past. Drilling in 2008 will further test the High Grade, Mann and Demann vein to add resources. One area to be tested will be the sulphide zone in the Cameron tunnel on the Mann vein that gave 3.4 meters of 398.8 g/t silver, 0.151 % copper, 0. 80 % lead and 2.16 % zinc. Sampling on surface 30 meters above this zone gave 3.65 meters of 1200 g/t silver, 0.129 % copper, 2.5% lead and 0.18 % zinc. Replacement type mineralization on the property consists of at least seven main and four minor replacement zones tested with trenches, previous open cuts, limited diamond drilling and/or adits in the past. The mineralization occurs along wide bodies that are up to 15 meters thick consisting of mainly barite, quartz, jasper, carbonates and sulfides with local native silver. Acanthite (silver sulphide) and stromeyerite (silver-copper sulphide) occur as veinlets, stringers and lenses in the High Grade and No 3 vein, giving rise to bonanza style grades. Between 1929 and 1938, the MB property produced 60 tons of hand cobbed material that yielded an average 546.8 oz/ton silver, 3.2 % copper and 3.15 % lead per ton of ore. In 1940, mining extracted 3.08 tons grading an average 0.09 oz/to gold, 248 oz/ton silver, 2.2 % copper, 4.9 % lead and 5.8 % zinc. In 1999, Mountain Boy Minerals extracted a 13.6 tonne (15 ton) sample from the High Grade vein with results from the smelter indicating a value of 18,854-grams/tonne silver (550 oz/ton), 1.1 % zinc and 2.5 % lead for this shipment. In drilling during 2006, a total of 5.18 meters assaying 5258.0 g/tonne silver was intersected in DDH-2006-10. Based on the surface and underground sampling and drilling, an indicated resource totaling 105, 555 tonnes grading 0.064 % copper, 0.69 % lead, 2.01 % zinc, 208.9 g/t silver and 13.59 % barite has been outlined in a very small portion of three different veins. A complete report is filed on Sedar dated June 20, 2003. The potential exists for several million tonnes of mineralization as exploration has been in a small limited area on several vein structures.
