The Dore 162 occurrence is located in the north eastern head waters of Hemmingsen Creek, approximately 3.5 kilometres west of Harris Creek.

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. Plutonic rock of the Paleozoic and or Mesozoic Westcoast Complex is mapped in the area.

Scattered showings of chalcopyrite, specular hematite and massive sulphides occur in Karmutsen andesite, at one location in quartz stringers. A sample of the quartz stringers assayed 3.25 per cent copper (Sketch Map, Property File). A body of quartz monzonite intrudes the andesite to the south east and at one location chalcopyrite is reported in fractures along or near the contact.

In 2006 through 2010, the area was prospected as the Bruno 1-2 claims by Le Baron Prospecting. Sampling, in 2010, assayed up to 6.4 grams per tonne silver and 4.93 per cent copper (Assessment Report 33124).
