The Bearsden occurrence is located on the southern slope of Mount McClennan, at an elevation of approximately 1150 metres.

The area is underlain by Lower Paleozoic Eagle Bay metasediments consisting of chlorite-sericite-quartz schist and black graphitic schist. A northeast trending fault cuts the schist.

Locally, a schist hosts quartz veins with mariposite and galena.

An unknown sample type assayed 0.34 grams per tonne gold, 295 grams per tonne silver and 11.26 per cent lead (Old Mineral Deposit Inventory Form in Property File).

In 1977, a sample (3522) assayed 2 per cent lead and 130 grams per tonne silver (Assessment Report 6603).

In 2012, a sample (D7) of schist with quartz, mariposite and galena assayed 0.694 per cent lead, 13.99 grams per tonne silver (Assessment Report 33467).

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. In 2012, Montego Resources completed a program of rock sampling and airborne geophysical surveys on the area.
