Trading Symbol: (TSX: MTB) (OTC Other: MBYMF) (Frankfurt: M9U.F) STEWART, BC, May 15 /PRNewswire-FirstCall/ -- Mountain Boy Minerals Ltd. announces that a 100 % interest has been acquired in the Red Cliff property from Thundermin Resources Inc. The Red Cliff property is a former producing copper and gold property dating back to 1908 located about 20 kilometers north of Stewart, British Columbia in the Skeena Mining Division. It consists of 8 Crown Granted claims along Lydden Creek. The property is accessible by road approximately 1.5 kilometers from paved highway 37A and is underlain by lithologies of the middle Jurassic Hazelton Group. These rocks host significant precious and base metal deposits in the Stewart Camp including the Silbak Premier, Silver Coin, Sulphurets, Red Mountain and Eskay Creek deposits. Seven zones of copper-gold and/or gold mineralization occur on the property, which appear to align in a north - south direction. Highlights from historical work for the three main zones include: 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. During 1973 the lowest (700 foot) level of the mine was rehabilitated, sampled and partially open stoped. Here several parallel lenses of copper - gold mineralization were identified and sampled, the best lens in a north drift measured 16.46 meters long, 1.71 meters wide and averaged 6.5% Cu and 5.17 grams per tonne gold. This lens was probably an extension of a zone located in a south drift that yielded 1.31 % Cu and 0.3 gram per tonne gold over a width of 2.13 meters and a length of 14.63 meters. The zone was open to the south and north along strike. Twenty meters to the west, a parallel zone contained up to 2.02 % Cu and 0.7 gram/tonne gold over 1.37 meters and it too was open along strike. Drilling in 1988 and 1990 indicated that the zones extended to depth with the best intervals yielding 4.00% Cu and 2.06 grams/tonne Au over 1.59 meters. In addition, high grade gold zones are present in the area of the copper-gold zones with a drill hole in 1990 intersecting 1.10% Cu and 61.03 grams/tonne Au over 0.39 meters. Montrose Zone: this zone occurs approximately 1000 meters to the north of the Red Cliff zones and consists of silicified andesite associated with shearing with strong pyrite, chalcopyrite, galena and sphalerite mineralization. This zone has been developed along several short adits in a very steep part of the property. Initial sampling above the portal area to one of the adits gave 198 g/tonne Au across 2.59 meters. During 1939-41 a total of 59 tonnes mined averaged 84.4 grams/tonne Au, 101 g/tonne Ag, 0.91% Cu, 3.5% Pb and 4.41 % Zn. In 1979 surface sampling gave 19.3 grams/tonne Au across 2.43 meters while 1987 surface sampling returned 7.93 grams/tonne Au across 3.81 meters. Recent drill intercepts include 9.3 grams/tonne Au across 1.71 meters. Waterpump Zone: this zone was a discovery in 1989 and initial results yielded 11.4 grams/tonne Au across 9.48 meters. Recent drill intercepts gave 3.01 grams/tonne Au across 13.07 meters with several higher grade sections including 14.1 grams/tonne Au and 0.22% Cu over 1.01meters and 21.74 grams/tonne Au and 4.6% Zn over 0.70 meters. A second intersection yielded 4.82 grams/tonne Au over 2.38 meters. To date, all zones have had very few drill holes completed and exploration potential is excellent. Once the company has received all necessary government permitting, drilling will commence on the property. Terms of the acquisition include issuing 250,000 common shares of Mountain Boy Minerals Ltd as well as a 2 % NSR to Thundermin for 100 % of the property. A 1 % NSR interest can be purchased for $1,000,000.00. This agreement is subject to TSX approval. E. Kruchkowski, P.
