The Sit 6 occurrence is located on a west-flowing creek 800 metres west of Asitka Peak. The showing was located in 1991 by International Corona on their Sit 6 claim (Assessment Report 22018).

Locally the area is underlain by the Upper Triassic Savage Mountain Formation (Takla Group). This formation consists of greenish to red-brown intermediate porphyritic flows, augite porphyry basalt flow, chloritic tuffs and agglomerates, and minor intercalated epiclastic sediments. These stratified rocks are intruded by the Early Jurassic Asitka Peak stock. The stock ranges from hornblende and/or biotite granodiorite to quartz diorite. These rocks are cut by mafic dykes, generally less than 3 metres thick, which are finely feldspar porphyritic.

Geological mapping and prospecting were performed in 1991 by International Corona Corporation on their Sit 1 to Sit 7 claims. Corona re-examined previously discovered mineral occurrences, mostly from the 1974 work of Nomad Mines on their lapsed Asitka claim block (Assessment Report 22018). A large area between Asitka Lake, on the south, and Johanson Lake, on the north, was prospected by Corona, resulting in the discovery several new occurrences. Work included 25 man-days in the field, with 100 rock and 24 moss mat samples collected. Corona collected 1 sample from the Sit 6 showing. Sample 64514 was described as a 0.5-metre grab sample taken from a fracture zone with quartz and quartz-carbonate containing epidote, malachite. and native copper; the sample graded 0.3 per cent copper (Assessment Report 22018).
