The Redtop prospect is located on Mount McClennan, approximately 2.3 kilometres west- north west of the summit.
The Lower Cambrian part of the Eagle Bay Formation on Mount McClennan 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.
Locally, a 300 metre thick section of rusty, pyritic, quartz-sericite schist with intercalated meta-argillite and limestone. The strata strikes 110 degrees and dips 30 to 50 degrees northeast.
In 1962, a 1.5 metre chip sample assayed 0.17 grams per tonne gold, 18.9 grams per tonne silver, 0.08 per cent copper, 2.75 per cent lead and 3.15 per cent zinc (Assessment Report 436).
1983, a 2.0 metre thick chip sample (73513) of the pyritic unit, close to the base of the limestone assayed 3.4 grams per tonne silver, 0.015 per cent copper, 0.047 per cent zinc and 0.08 per cent lead (Assessment Report 12080).
In 1988, diamond drilling yielded:

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 (MINFILE 082M 045) and the Red Top Group. 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.
