The Corona showing is located 700 metres southeast of Asitka Peak and 3 kilometres east-northeast of Sustut Lake.

The Corona showing area is underlain by rock of the Upper Triassic Savage Mountain Formation (Takla Group). These stratified rocks are intruded by the Early Jurassic Asitka Peak stock about 800 metres east of the Corona occurrence. The stock consists primarily of quartz diorite. Rock types mapped by International Corona in the showing area include pyroxene porphyry, fragmental volcanic, agglomerate, dacite feldspar porphyry and basalt flows with intercalated red greywacke.

In 1991, about 700 metres southeast of Asitka Peak, International Corona collected sample 64609 which graded 0.56 per cent copper and 3.3 grams per tonne silver; sample 64606, taken 330 metres southeast of Astika Peak, graded 0.19 per cent copper (Geochemical Map (showing samples and assays), Assessment Report 22018). International Corona described sample 64609 as a maroon volcanic with stringers and blebs of chalcopyrite, chalcocite and malachite. Quartz stringers were noted in the vicinity. Sample 64606 was taken at a location consisting of epidote pods with quartz and traces of malachite and chalcocite.
