Epithermal Deposits

High sulfidation epithermal deposit at Thor (Great Northern Zone). This piece of core contains visible tetrahedrite, sphalerite and quartz.

Epithermal Deposits

The Thor epithermal deposit is actually composed of a number of high-sulfidation epithermal veins that contain sphalerite, tetrahedrite, chalcopyrite and galena within quartz-carbonate veins.

The epithermal deposits crosscut the host rocks of the Broadview, Jowett and Sharon Creek Formations and are related to a much younger event than the folding that produced the Silver Cup Anticline. Epithermal deposits occur along the west edge of the prominent aeromagnetic feature, demonstrating it is related to a much younger north-northwest trending event that introduced the valuable metals into the epithermal deposit.
