STEWART, BC, Jan. 30 /CNW/ - Mountain Boy Minerals Ltd. announce that a drilling program on Mountain Boy's 100% owned MB property confirmed bonanza style silver mineralization. The MB property is located about 22 kilometres north of Stewart and is road accessible along the American Creek valley.
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 a13.6 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.
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.
Due to the steep nature of the terrain, a drill station was blasted out below the High Grade vein and 14 holes drilled from this station using an underground drill to fan a series of holes from this location. In the course of stripping of the High Grade vein using a small excavator in order to build the drill station, massive acanthite (argentite) stringers up to 15 cm wide were exposed along several meters of length in a fault zone that intersects the vein. The full length of the mineralization was not exposed due to the deep overburden on either end of the exposure. This orientation of veining has never been seen in the past and may represent feeders to high grade mineralization found in the High Grade and No 3 veins. Grab sampling of these stringers has yielded over 15,000 g/t silver.

It should be noted that the High Grade vein has only been tested along a 100 meter section in the southern portion of the Mountain Boy claim. Based on newspaper accounts, bonanza style silver mineralization apparently occurs several hundred feet (60 meters) south of the area of drilling. In addition the No 3 vein located 100 meters topographically above the High Grade vein has reported grades that contain 0.91 meters of 12,917 g/T, 0.46 meters of 18,361 g/T, 0.91 meters of 13,569 g/t and 1.22 of 6,361 g/T silver over a strike length of 100 meters along this vein.. The High Grade vein has been traced over a length of 457 meters and the No 3 vein has been traced over a strike length of 550 meters. The No 3 vein appears to strike into the former Silver Mask claim (present Stromeyerite claim owned by Mountain Boy) which appears to have similar high grade mineralization. On the Silver Mask claim, an article in the June 28, 1929 edition of the Stewart News indicates that a vein 1.83 meters (6 feet) wide was located on this claim. The article describes the vein as similar to the High Grade vein on the Mountain Boy property approximately 500 meters away with "copper sulphides mixed with bunches and stringers of native silver. Four additional veins have been located, some of them with similar high grade ore and some carrying galena in massive form".
Future work will try to locate all previously reported mineralization on the High Grade and Mo 3 vein as well the showings on the former Silver Mask claim and extend the known strike length of the cross-cutting massive argentite found during stripping for the drill station..
