Capsule Geology

The Dev occurrence, located between the head waters of the Nabesche and West Nabesche rivers, 12 kilometres north of Mount Burden and 110 kilometres north of the town of MacKenzie.

Regionally, the area is underlain by Paleozoic platformal carbonates of the Ancestral North America terrane, including Silurian Nonda Formation, Silurian-Devonian Muncho-McConnell Formation and Lower and Middle Devonian Stone Formation and Middle Devonian Dunedin Formation dolomites and limestones, overlain by Devonian and Carboniferous Besa Formation shale, comprise the southeast limb and south plunging nose of the Bernard anticline.

Locally, pale yellow sphalerite occurs very finely disseminated in calcite/white dolomite veins and the matrix of a Dunedin Formation limestone bed. Disseminated galena occurs in a 180- by 120-metre area.

Grab samples from the first showing assayed greater than 1 per cent zinc, while a grab sample from the northeast corner or the claims assayed 1.5 grams per tonne silver, 0.0272 per cent copper, 0.0030 per cent lead, 1 per cent zinc and 0.0760 per cent cadmium (Assessment Report 4791).

Work History

In 1973, Canadian Superior Exploration Ltd. completed a program of prospecting, geological mapping and geochemical (rock and soil) sampling on the area as the Dev group of claims.
