In the early 1900's, work consisted of drifts and shafts (one up to 14 metres) on several claims. In 1929, pyrite and chalcopyrite in quartz was noticed in volcancis. A 0.6-metre sample assayed 2.4 per cent copper and 28 grams per tonne silver.

In 1969 Granby Mining Company Limited conducted magnetmetre survey over the claims.

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Attwood area of the Greenwood property.
