Grab samples from silicified shear zones in Lower to Middle Ordovician Active Formation argillites were collected from a series of old trenches on the Aspen showing. Sulphide mineralization ranges from disseminated to massive and consists of galena, sphalerite and pyrite. Limonite staining is common. The length of the zone of mineralization is reported to be 180 metres.

Samples assayed as high as 6.7 per cent lead, 7.4 per cent zinc, 272 grams silver and 1.29 grams gold (Assessment Report 12985).
