Capsule Geology

The John showing is underlain by sediments of the Lower Jurassic Elise Formation, Rossland Group. The host rocks consist of thin- bedded limestones and argillites lying above massive limestone. The bedding strikes 153 degrees and dips 40 degrees to the southwest.

Workings, consisting of a pit and an 18-metre long adit, explore a fissure which varies from a crack to 0.45 metres in width. Pyrite is reported to be the main visible mineral. The fissure is vertical and strikes 100 degrees. In 1954, a shipment consisting of 7.2 tonnes of "development rock" was made to the Trail smelter. The ore produced 404 grams of silver, 79 kilograms of lead and 145 kilograms of zinc (Minister of Mines Annual Report 1954, page 153).
