The occurrence is situated at the contact between andesite, dacite, tuff and breccia of the Lower Jurassic Hazelton Group and Late Cretaceous to Eocene intrusive rocks. Rocks along the contact zone contain calcite, potassium feldspar and quartz as alteration products. Mineralization consisting of chalcopyrite, bornite, tetrahedrite, pyrite, magnetite, with minor sphalerite and galena occurs as disseminations in the granitic/dioritic intrusive and as fracture fillings in the contact zone.

In 1969, the occurrence was explored by Telkwa Mountain Mines Limited as the Starr Creek property. Twenty-two rock chip samples were assayed and returned values ranging from a trace to 2.15 per cent copper over 3 metres. Other significant chip samples assayed included 0.37 per cent copper over 45 metres, 1.31 per cent copper over 9 metres and 1.62 per cent copper over 7.5 metres (Property File Cyprus Anvil T. Kikuchi, 1969).
