The Mitchell vein is located 0.4 kilometre east of the Kitsault River, 25 kilometres north of the town of Alice Arm. A soil sample survey carried out by Dolly Varden Mines led to the discovery of this silver-bearing vein in 1971.

The area is underlain by a sequence of volcanics and sediments of the Upper Triassic Stuhini Group and the Lower-Upper Jurassic Hazelton Group. The sequence is folded into the doubly plunging, north-northwest trending Kitsault River syncline. This sequence has been regionally metamorphosed to greenschist facies.

The Mitchell showing is comprised of a west-northwest trending quartz-carbonate vein that has been traced for 244 metres in propylitized andesitic tuff of the Hazelton Group. In surface exposures it varies from 0.3 to 2.3 metres in width. Its eastern extension has been segmented by a series of faults displaying dextral movement. Mineralization comprises pyrite, galena and sphalerite in a gangue of quartz and carbonate. A grab sample from the eastern extension of the vein assayed 79.5 grams per tonne silver, 11.0 per cent lead, 4.40 per cent zinc (Assessment Report 7098, page 28).

During 2010 through 2019, Dolly Silver Corporation explored the area as apart of the Dolly Varden property. A complete property exploration history can be found at the Dolly Varden (MINFILE 103P 188) occurrence.
