The Sunrise prospect is located on Mount McClennan, approximately 750 metres south east of the summit.

Lower Cambrian Eagle Bay Formation rocks on Mount McClennan are comprised of 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 massive sulphide horizons, up to 1.2 metre thick and over a 150 metre length, within flat-lying quartz sericite schist and close to the nose of the antiform.

In 1970, a select high grade sample of dump material assayed 3.43 grams per tonne gold, 106.3 grams per tonne silver, 0.14 per cent copper, 2.15 per cent lead, 28.3 per cent zinc and 0.18 per cent cadmium (Assessment Report 5813).

In 1983, a 2.0 metre chip sample (SF4) from the main showing assayed 1.73 grams per tonne gold, 225 grams per tonne silver, 2.62 per cent lead, 18.3 per cent zinc and 0.13 per cent copper (Assessment Report 12080).

In 1988, diamond drill hole 88DD04, located immediately east of the adits, intercepted 0.73 metre yielding 0.13 per cent copper, 0.56 per cent lead, 0.39 per cent zinc and 8 grams per tonne silver. Fifteen rock samples (34023 through 34038) from the adit area yielded values from 0.016 to 0.193 per cent copper, 0.045 to 3.4 per cent zinc, 0.009 to 3.98 per cent lead, 0.3 to 167.0 grams per tonne silver and 0.025 to 0.535 grams per tonne silver (Assessment Report 18647).

In 2005, a 1.5 metre sample (S-10) from a massive sulphide layer assayed 0.11 grams per tonne gold, greater than 30 grams per tonne silver 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, the Snow Group (MINFILE 082M 045) 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.
