The McCorvie Lake occurrence is located on the western side of a logging road, approximately 420 metres west of the north end of McCorvie Lake.

The area is underlain by chlorite schist and greenstone of Lower Cambrian age and phyllite with intercalated sediments of Mississippian age, both of the Eagle Bay Formation.

Locally, mineralized quartz veins with ankerite are hosted by schists and/or calcareous sediments. Mineralization consists of pyrite, pyrrhotite, sphalerite and galena. The veins are reported to be discordant and concordant with stratigraphy.

In 1988, a rock sample (34099) assayed 0.10 per cent zinc, 3.4 grams per tonne silver and 3.3 grams per tonne gold (Assessment Report 18647).

In 1989, a sample (43076) assayed 4.48 per cent lead, 5.67 per cent zinc, 69.4 grams per tonne silver and 6.47 grams per tonne gold (Assessment Report 20019).

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. During 1983 through 1988, Placer Development completed programs of geological mapping, ground and airborne geophysical surveys and geochemical sampling 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 2010, the area was prospected as the Sunrise East claims.
