The North Tsowwin occurrence is located on the east side of North Tsowwin Creek, at an elevation of 365 metres. The occurrence has been explored in conjunction with the nearby Vivian (MINFILE 092E 006) occurrence.

The area is underlain by Upper Triassic Vancouver Group volcanics and sediments comprised of Karmutsen Formation basalts and carbonates and clastics of the Quatsino and Parson Bay formations. Granodiorite of the Early to Middle Jurassic Island Plutonic Suite and Eocene Catface or Mount Washington Intrusions has intruded the Vancouver Group rocks.

Locally, an auriferous, shear-hosted, 10 centimetre wide, quartz vein strikes 150 degrees and dips 80 degrees to the northwest. The vein is described as being similar to the Vivian vein and is located 680 metres along strike from the adits on the Tsowwin River. In 1992, a grab sample (509156) assayed 1.41 grams per tonne gold and greater than 10,000 parts per million arsenic (Assessment Report 22335).

In 2012, Canadian Dehua International Mines Group Inc. completed air photo interpretation on their Head Bay Property, covering the Glengarry and Elaine past producers, the Rob Roy, Head Bay and Vivian prospects, and the Mohawk, Middle Quarry, Upper Quarry and North Tsowwin showings. Active exploration continued throughout 2014 and 2015 on the Head Bay property.

During 1979 through 1981, Pan Ocean Oil completed programs of geological mapping and geochemical sampling on the area as the Tah 1-19 claims. In 1983, Aberford Resources continued the previous mapping and sampling programs. In 1984, Homestake Canada completed a program of geological mapping and rock sampling. In 1987, the Vig 6 property was staked to cover the occurrences and a program of rock and soil sampling was completed. In 1992, a program of geological mapping, prospecting and geochemical sampling was completed. In 2007 and 2008, Silverlake Capital completed programs of geochemical sampling and geological mapping on the area. During 2009 through 2013, Homegold Resources completed programs of prospecting, historical literature reviews and air photo interpretations on the area as part of the Head Bay property.

In 2019, the North Tsowwin showing was part of the Vivian property where rock chip sampling was conducted over a new road cut by geologist A. Kikauka. One sample analysed had elevated gold values of 0.07 gram per tonne and 1.5 parts per million tellurium.
