COMPANY HAS RECEIVED GOVERNMENT PERMITTING FOR A WORK PROGRAM ON THE RED CLIFF PROPERTY AND DRILLING HAS COMMENCED USING 2 DRILL RIGS
Mountain Boy Minerals Ltd. has mobilized two drills on to the Red Cliff property using old roads created in the 1980s. The drills will test the historic copper-gold and gold zones on this property.
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:
This zone contains 2,300 metres of underground development on five levels from four portals over a height of several hundred metres with limited Cu-Au production reported in 1910 to 1912 and 1973. From 1910-to-1912 production from the Redcliff zone amounted to approximately 1,136 tonnes estimated to average 5 per cent Cu. In 1972, approximately 3,776 tonnes of ore were 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 per cent 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 metres long, 1.71 metres wide, and averaged 6.5 per cent 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 per cent Cu and 0.3 gram per tonne gold over a width of 2.13 metres and a length of 14.63 metres. The zone was open to the south and north along strike. Twenty metres to the west, a parallel zone contained up to 2.02 per cent Cu and 0.7 gram per tonne gold over 1.37 metres 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 per cent Cu and 2.06 grams per tonne Au over 1.59 metres. In addition, high-grade gold zones are present in the area of the copper-gold zones with a drill hole in 1990 intersecting 1.1 per cent Cu and 61.03 grams per tonne Au over 0.39 metre.
This zone occurs approximately 1,000 metres 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 grams per tonne (g/t) Au across 2.59 metres. During 1939 to 1941, a total of 59 tonnes mined averaged 84.4 grams per tonne Au, 101 g/t Ag, 0.91 per cent Cu, 3.5 per cent Pb and 4.41 per cent Zn. In 1979, surface sampling gave 19.3 grams per tonne Au across 2.43 metres, while 1987 surface sampling returned 7.93 grams per tonne Au across 3.81 metres. Recent drill intercepts include 9.3 grams per tonne Au across 1.71 metres.
This zone was a discovery in 1989 and initial results yielded 11.4 grams per tonne Au across 9.48 metres. Recent drill intercepts gave 3.01 grams per tonne Au across 13.07 metres with several higher-grade sections, including 14.1 grams per tonne Au and 0.22 per cent Cu over 1.01 metres and 21.74 grams per tonne Au and 4.6 per cent Zn over 0.7 metre. A second intersection yielded 4.82 grams per tonne Au over 2.38 metres.
To date, all zones have had very few drill holes completed and exploration potential is excellent.
