The Fin occurrence is located on the western flank of Mount Finlay, between the Finlay River and Cutoff Creek, about 222 kilometres northwest of the community of Germansen Landing. The Urn showing (094E 220) is located approximately 480 metres to the northwest.
The showing area is underlain by a sequence of Lower Cambrian Atan Group sediments comprising a thick sequence of phyllitic limestone, shale, shaley limestone, dolomite, siltstone, sandstone, phyllites, and pure and impure quartzite. Feldspar porphyry dikes follow late normal faulting in the area.
Locally, quartz veins surrounded by discrete gossan envelopes host malachite, tetrahedrite, and chalcopyrite with minor specular hematite.
The first recorded activity in the area of the Fin claims was a program of soil sampling and rock geochemistry in 1981 by UMEX Inc. This program outlined a significant coincident lead-zinc-copper soil anomaly over a one kilometre strike. No further work is recorded after this date.The Fin claims were staked in March 1992 by Major General Resources Inc. under agreement with Kennecott Canada Inc. In 1992, a program of prospecting and rock chip sampling was completed on the Fin claim. One rock sample (FKG-002) of mineralized quartz vein material yielded greater than 1 per cent copper; rock sample FKG-001 assayed 0.41 per cent copper and 5.8 grams per tonne silver (Assessment Report 22768).
