The area of the Dick Pass showing is underlain by Devonian to Permian Stikine Assemblage rock overlain by Upper Triassic rock of the Stuhini Group. The stratigraphy is intruded by Triassic to Tertiary stocks of the Coast Plutonic Complex.
In 1989, Corona Corporation prospected the Lisa 1, 2, 5, DD2 and JJ2 claims (of the Inhini property) and collected 31 heavy mineral, 25 silt and 141 rock samples (Assessment Reports 19972). In 1990, Link Resources Inc. carried out a 700-kilometre airborne magnetic and EM survey over the entire Inhini Property (Assessment Report 20972).
Numerous mineralized talus boulders located on the west side of Dick Pass were traced upslope to an elevation of 1600 metres where a 10 metre wide grey, feldspar porphyry dike, strikes 055 degrees and cuts black-grey argillaceous sediments. Although exposure in the area is poor, the broken rock on surface is subcrop derived. Along the apparent margins of this dike, quartz vein boulders (up to 0.5 cubic metres) are exposed containing minor disseminated specular hematite, galena, tetrahedrite, azurite and malachite. In places, the vein is a vuggy quartz breccia vein containing fragments of argillite. Subcrop exposure of this vein can be traced over 55 metres into talus.
The upper, subcrop, vein material assayed 11.52 grams per tonne gold, 17,139.57 grams per tonne silver, 2.91 per cent copper, 0.54 per cent zinc and 0.05 per cent lead (Sample 89049, Maps 5d and 6d, Assessment Report 19972).
