The Arsenault East occurrence is located on the east flank of Mount Francis about 10 kilometres east of Swift Lake, approximately 112 kilometres east of the community of Atlin.

The showing is underlain by a moderately steeply east dipping, strongly deformed section of decimetre-thick interbeds(?) of limestone and tuff of the Paleozoic Big Salmon Complex. These are infolded with clean quartzite. Within the carbonate, near the quartzite contact, is a well developed vein replacement zone of garnet-epidote-quartz-calcite-magnetite-actinolite-chalcopyrite. The zone is 2.5 metres wide and is exposed for 10 metres along strike. Chalcopyrite is concentrated in the northern third of the zone in pods and irregular veins up to 4 centimetres wide and as much as 30 centimetres long. Mineralized chips collected across the 2.5 metre wide zone yielded 4.6 per cent copper, 0.3 per cent zinc, 9.5 grams per tonne silver, 322 parts per million cobalt, 26 parts per million cadmium and 115 parts per million bismuth (Fieldwork 1997, page 6-17).

In 1998, S. Traynor conducted a detailed program of prospecting and geochemical sampling, which included a re-examination of old trenches and available drill core, on the Arsenault showing (104O 011). Some samples were taken near the Arsenault East showing which is located about 1.7 kilometres east of the Arsenault showing.
