The Bear vein occurs in an area of 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 Inhini 9-12, DD1 and JJ1 claims and collected 13 heavy mineral, 13 silt and 43 rock samples (Assessment Reports 19150 and 19971). In 1990, Link Resources Inc. carried out a 700-kilometre airborne magnetic and EM survey over the entire Inhini Property (Assessment Report 20972).

The Bear showing on the Inhini 12 claim of Corona Corp consists of a 1-3 metre wide quartz vein that pinches out over 30 metres. It is locally well mineralized, containing a pod (0.5 by 1.0 metre) of massive galena and sphalerite. A sample (55004) taken of the massive sulfide mineralization ran only 90 parts per billion gold. A second sample (55066) on the same vein yielded the highest gold value of 0.6 gram per tonne. This vein occupies the contact between a limestone unit and a large pluton of granodiorite and, although locally well mineralized, overall the vein is poorly mineralized. One sample assayed 0.33 gram per tonne gold, 646.29 grams per tonne silver greater than 2 per cent zinc and 2 per cent lead (Figures 4b and 5b, Assessment Report 19971).
