The Jarr occurrence is located is located in the head waters of Head Creek, at an elevation of approximately 350 metres.
The area lies within the Insular Belt and is underlain mainly by volcanic and crystalline rocks and minor sediments. Andesitic to rhyodacitic lava, tuff and breccia of the Lower Jurassic Bonanza Group overlie an assemblage of Paleozoic Sicker Group sediments and basalts and Upper Triassic Vancouver Group minor carbonate and clastic sediments. The Bonanza Group volcanics are coeval with, or genetically related to granodiorite stocks of the Jurassic Island Intrusions, which intrude all rocks in the area.
The occurrence is underlain by calcareous sediments of the Parson Bay Formation (Vancouver Group) and volcanic rocks of the Bonanza Group which are complexly folded and faulted and intruded by dikes. Locally, chalcopyrite occurs as low-grade disseminations and in skarn, associated with pyrite, pyrrhotite and magnetite, at or near an east trending fault.
Work History
