Capsule Geology

The Dore 97 occurrence is located on a south flowing un-named tributary of Hemmingsen Creek, approximately 1.7 kilometres south west of the summit of Mount Bolduc.

The area is underlain by a series of basaltic flows and related pyroclastics of the Karmutsen Formation and is overlain by, or interbedded with, limestone of the Quatsino Formation; both units belong to the Upper Triassic Vancouver Group. Andesite to rhyolite tuffs and breccias, with minor intercalated greywacke and argillite, of the Lower Jurassic Bonanza Group overlie the Upper Triassic rocks. Intruding this stratigraphic assemblage is the Early to Middle Jurassic Island Plutonic Suite of monzonite to diorite composition.

Locally, chalcopyrite occurs on a slip in limestone. A contact with a stock of the Early to Middle Jurassic Island Plutonic Suite diorite to quartz monzonite occurs within a few hundred metres to the west of the showing. Chalcopyrite is also reported to occur as disseminations within the intrusive, about 300 metres to the north west.

In 2007 through 2009, Le Baron Prospecting completed a program of prospecting on the area as the Hemmingsen Creek project (claim 535954).
