The Snow prospect is located on Mount McClennan, approximately 750 metres west- south west of the summit.
The Lower Cambrian part of the Eagle Bay Formation on Mount McCleannan comprises metasediments and metavolcanics, which are deformed into a shallow plunging east trending antiform. The rocks, which occupy the north limb of the structure, include quartzite, chlorite-muscovite-quartz schist, quartz-sericite schist, limestone, calc-silicate schist and skarn. Stratiform lenses of massive, semi- massive and disseminated pyrite and pyrrhotite with lesser galena, sphalerite and chalcopyrite occur in pyritiferous, siliceous and recrystallized units.
The occurrence consists of four "semi-conformable", 0.3 to 1.2 metre wide bands of massive sulphide within a 12.2 metre thick, flat-lying unit of carbonate bearing quartz-sericite schist. Zinc rich bands grade upward into copper rich bands and chalcopyrite is partially mobilized into north trending tension fractures.
In 1962, a 0.6 metre sample assayed 1.70 per cent copper, 8.25 per cent lead and 2.57 per cent zinc (Assessment Report 436). In 1983, chips from several mineralized blocks assayed 1.18 per cent copper, 0.80 per cent zinc, 2.10 per cent lead, 140 grams per tonne silver and 0.12 grams per tonne gold (Sample 48704A; Assessment Report 12080). In 1988, rock samples from the adit area yielded up to 0.15 per cent copper, 0.18 per cent zinc, 2.95 per cent lead and 43 grams per tonne silver (Assessment Report 18647).
In 1988, diamond drill hole 88DD03, located on the west side of a small pond approximately 120 metres west of the adits, intercepted 1.12 metres yielding 0.78 per cent lead. Three rock samples (34040 through 34042) from the area of the drill hole assayed from 0.101 to 2.7 per cent copper, 0.135 to 2.53 per cent zinc, 0.91 to 5.85 per cent lead, 33 to 270 grams per tonne silver and 0.02 to 0.27 grams per tonne gold (Assessment Report 18647).
In 2005, a 0.4 metre sample (12A) assayed 0.57 grams per tonne gold, greater than 30 grams per tonne silver, 0.27 per cent lead, greater than 0.1 per cent cadmium and greater than 1.0 per cent zinc. Another 0.4 metre sample (13A) yielded 0.17 grams per tonne gold, greater than 30 grams per tonne silver, 0.979 per cent copper and greater than 1.0 per cent lead and zinc, respectively (Assessment Report 28345).
The area was originally staked in the 1920’s as the Last Chance (MINFILE 082M 032), Sunrise Group or Naomi (MINFILE 082M 046), the Snow Group and the Red Top Group (MINFILE 082M 044). In 1962, Herslev & Humphrey completed a program of geological mapping, sampling and a dip needle survey on the area as the Sinbad and Roc claims. In 1966, Crowpat Minerals optioned the property and completed three diamond drill holes, totalling 451.5 metres. During 1969 through 1971, Calby Mining completed five diamond drill holes, totalling 365.4 metres, and trenching. In 1975 and 1976, Kerr-Dawson Associates completed a program of geological mapping and soil sampling on the area as the Nimsic claims. In 1977, Canadian Nickel completed a program of geological mapping, soil sampling and ground electromagnetic and magnetic surveys. In 1978, Craigmont Mines completed a program of geophysical surveys and five diamond drill holes, totalling 382.9 metres. During 1983 through 1988, Placer Development completed programs of geological mapping, ground and airborne geophysical surveys, geochemical sampling and 4 diamond drill holes, totalling 952.3 metres, on the area as the Noble 1-6 claims. In 1989, Placer Dome and Denison Mines completed a program of geological mapping, rock and soil sampling and ground geophysical surveys. In 2005, a rock sampling program was completed by Hunter Dickson Inc. In 2012, Montego Resources completed a program of rock sampling and airborne geophysical surveys on the area.
