Summary:
The Property contains “Sedex-Type” stratabound zinc-lead mineralization hosted by calcsilicate rocks, which have been intruded by pegmatite dykes and sills. The main deposit, which has been the historical focus of exploration on the Property is known as the E Zone.
Mineralization at Ruddock Creek consists of a conformable planar massive sulphide horizon, exposed intermittently for over 5 kilometres along strike. The Ruddock Creek Sulphide Horizon consists dominantly of calc-silicate rocks, pegmatites and lesser biotite schist. Lenses of massive sulphide, composed of sphalerite, pyrrhotite and galena in order of abundance are hosted by the calc-silicate portions of the package. The Ruddock Creek Sulphide Horizon varies from less than 5 m to over 50 m in true thickness. Massive sulphide lenses consist of sphalerite, pyrrhotite, galena, pyrite and minor chalcopyrite, and are generally medium grained.

The Ruddock Creek Sulphide Horizon varies from less than 5 m to over 50 m in true thickness. Massive sulphide lenses consist of sphalerite, pyrrhotite, galena, pyrite and minor chalcopyrite, and are generally medium grained. The coarser grain size is thought to be a result of recrystallization during the metamorphic event. They are often complexly folded within themselves on axes that plunge to the west. The folds within the sulphide layers are usually irregular in form. Galena and sphalerite also occur as scattered grains in marble and calcareous quartzite occasionally associated with fluorite.
Multiple individual massive sulphide lenses are present within the horizon, ranging from less than 1m to greater than 5m in true thickness, separated by variable thicknesses of non mineralized pegmatite, calc-silicate or biotite schist. Locally these stacked lenses of massive sulphide and host rock, attain true thicknesses of over 30 m of ore grade material.
There have been nine zones of mineralization identified on the Property to date: E, F, G (including the Upper and Lower G), M, T (including the Upper and Lower T and Creek Zone) in the eastern half, and the U, V, R, and Q which occur as contorted layers and lenses forming the western half. The mineralization at the E Zone has been the main focus of most previous exploration programs as it is the best exposed and contains the most continuous ore horizons known to date.
