The Tinkirk occurrence is located east of Peavine Creek, a south flowing tributary of the North Thompson River and at an elevation of approximately 884 metres.

The area is underlain by Lower Cambrian part of the Eagle Bay metavolcanics consisting of chlorite schist and greenstone and a conformable north-west trending band of limestone.

Locally, an adit exposes a schist hosting a 4 to 10 metres wide irregular, discordant quartz vein, containing seams, about 3.8 centimetres wide, mineralized with pyrite and galena with associated calcite and ankerite. The mineralization is hosted in the footwall of a faulted package of greenstone.

A sample of one of the veins assayed 20.6 grams per tonne gold and 13.7 grams per tonne silver (Annual Report 1922).

In 1986, a sample (48640) of vein material from the dump at the adit entrance assayed 0.045 per cent copper, 0.047 per cent zinc, 0.23 per cent lead and 76.0 grams per tonne silver (Assessment Report 15817).

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 2011, the area was prospected as the Peavine property.
