Capsule Geology

The area of the Erie occurrence is underlain by siltstone and conglomerate of the Archibald Formation and argillite and siltstone of the Hall Formation, both of the Lower Jurassic, Rossland Group. The northwest trending Erie Creek fault forms the boundary of the two formations east of Erie Lake with the Hall Formation on the east. A small mass of granitic rock of the Middle to Late Jurassic Nelson Intrusions disrupts the strata to the immediate north. The location of two adits are marked on Map 1145A just east of the Erie Creek fault in Hall Formation rocks.

A small vein, up to 25 centimetres wide, containing galena, sphalerite and chalcopyrite in a siliceous gangue, occurs in schistose rocks. In 1928, the vein was drifted on for 53 metres with two winzes developed for an additional 9 and 12 metres respectively. A grab sample from a pile of sorted ore assayed 229.72 grams per tonne silver, 21.8 per cent lead, 2.26 per cent copper and 4.3 per cent zinc (Minister of Mines Annual Report 1928, page 338). A sample from a wide iron-capping exposed in an opencut near the adit assayed 0.69 grams per tonne gold, 20.57 grams per tonne silver, 0.5 per cent lead and 0.6 per cent zinc (Minister of Mines Annual Report 1928, page 338).
