The Granodiorite zone is located south of the Blackwater River, approximately 80 kilometres northwest of Quesnel.

The area is underlain by Cache Creek Group sedimentary and volcanic rock in contact with granodiorite and ultramafic intrusives.

Locally, sediments are intruded by the Topley intrusion as evident by the sediments generally occurring as inclusions in the granodiorite. The sedimentary inclusions carry disseminated sulphides, pyrite and pyrrhotite.

Between 2006 and 2010, a program of prospecting, geological mapping and rock geochemical sampling was completed. Previous work in the area was performed by Rio Tinto, during 1967 to 1970, and included three drill holes, totalling 469.5 metres, and various geophysical surveys. Drill hole A-8, by Rio Tinto, was uniformly mineralized with chalcopyrite, molybdenite and pyrite between 28.8 to 150 metres and returned up to 0.25 per cent copper and 0.38 per cent molybdenite (Assessment Report 28536).
