Trading Symbol: TSX-MTB Frankfurt-M9U.F OTC-MBYMF STEWART, BC, Sept. 6 /PRNewswire-FirstCall/ -- Mountain Boy Minerals Ltd. announces that drilling is proceeding on three different properties; namely the BA, Red Cliff and MB. BA Property: A drill has been mobilized to the BA property and a system of close spaced holes 15 meters on a grid pattern apart will be completed in order to provide the data for a resource calculation. An excavator has been flown into the property in order to build trails along the grid, build drill pad locations and move the drill between set ups. The BA property hosts a zone representing a portion of a Kuroko-type VMS system composed of an exhalite horizon with related zinc-lead-silver mineralization in felsic rocks. Drilling is concentrating on the southwest portion of this system where drilling in 2006 indicated 10.31 meters of 152.19 g/t silver 4.67 % lead and 4.05 % zinc. The main exhalite horizon is 40 to 50 meters wide and can be traced for over 1 kilometer of width. Geological Survey of Canada Open File 2931 indicates that the favorable horizon occurs within a syncline that is up to 3 kilometers across. At present, this mineralized horizon is being drill tested on the west limb of the above syncline. Redcliff Zone: this zone contains 2,300 m of underground development on 5 levels from 4 portals over a height of several hundred meters with limited Cu-Au production reported in 1910-12 and 1973. From 1910 - 12 production from the Redcliff zone amounted to approximately 1,136 tonnes estimated to average 5% Cu. In 1972 some 3,776 tonnes of ore was sent to a local mill. The only reserve estimate reported for the Redcliff Zone was in 1912 showing a total of 18,900 tonnes averaging 3.19% Cu and 2.86 grams per tonne gold. This estimate was only for broken mineralized material within a stope on one of the levels in the mine. This estimate is historical and is not 43-101 compliant and is used for reference purposes only. Drilling during 2007 has extended the earlier defined zones well below the lowest working from the previous work as well as indicating that 4 separate zones of copper -gold mineralization are present. Phase II drilling is concentrating to the west and at depth to the early underground work as well as Phase I drilling (see September 4, 2007 press release) MB Property: 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. Drilling in 2006 yielded 5.18 meters of 5258.0 g/tonne silver in DDH-2006-10. E. Kruchkowski, P.
