The Brin 370 occurrence is located at an elevation of approximately 1600 metres along a northeast-flowing tributary of Horn Creek and approximately 10 kilometres southeast of Lady Laurier Lake.

Regionally, the area is underlain by dolomitic carbonate rocks of the lower Silurian Nonda Formation, upper Silurian to Middle Devonian Muncho-McConnell Formation, upper Silurian to Middle Devonian Stone Formation and Dunedin Formation, overlain by shales of the Upper Devonian to Mississippian Besa River Formation. These units lie on the northeast flank and core of the Bernard anticline, a prominent north-trending structure. The north end of the Bernard anticline terminates in a small dome overlain by upper Silurian and Lower Devonian strata.

Locally, the style and type of mineralization is not reported but is likely similar to other occurrences in the area and comprises stratabound lead-zinc mineralization in carbonate rocks.

In 1972, an outcrop sample (3567R) assayed 0.26 per cent lead and 2.5 grams per tonne silver (Assessment Report 3976).

Work History

During 1972 through 1974, British Newfoundland Exploration Ltd. completed programs of prospecting, geological mapping and geochemical (rock, silt and soil) sampling on the area as the Brin and West claim groups of the Westoll, Lake, Horn and Reef properties.
