Capsule Geology

According to the Geological Survey of Canada Summary Report 1913 the Stemwinder showing consists of a 30 centimetre band of dominantly pyrrhotite overlain by a 45 to 60 centimetre band of metamorphic silicates. The ore material occurs between limestone and finely textured andesite. The material is exposed for a distance of 3 to 5 metres along surface. No assays were reported.

The British Columbia Department of Mines Annual Report for 1911 describes the Stemwinder showing as a magnetite deposit from 2.4 to 3 metres in width. The magnetite is reported to contain values in gold and copper.
