The Glengarry occurrence is located southwest of the Sucwoa River, approximately 1.5 kilometres north west of the river mouth on Head Bay.

The area is underlain by Upper Triassic Vancouver Group volcanics and sediments comprised of Karmutsen Formation basalts and the Quatsino and Parson Bay formations carbonates and clastics. Granodiorite of the Early to Middle Jurassic Island Plutonic Suite and Eocene Catface Intrusions has intruded the Vancouver Group rocks. Contact metamorphism in Karmutsen basalts has given rise to amphibolite and hornfels zones up to several thousand metres in thickness. Contact metamorphism grades into regional zeolite facies metamorphism.

Locally, at the Glengarry magnetite occurrence, the northwest striking Quatsino limestone dips about 45 degrees to the southwest. Intruding the limestones to the south and east is a large granodiorite body and associated diorite dikes. The limestone strata have been recrystallized or altered to garnetite and many of the crosscutting dikes predate the skarn event.

Mineralization outcrops over an area of 567 by 403 metres as 11 or more pods of magnetite within garnet skarn. The pods range from 2 to 12 metres wide and are parallel to bedding, following roughly the margin of the intrusive contact in a northwest direction. Chalcopyrite and pyrite are present only in small quantities. A sample of the magnetite assayed 56.8 per cent iron, 0.1 per cent sulphur, trace phosphorous and 1.6 per cent silica (Minister of Mines Annual Report 1916, page K293).

Drill indicated reserves, in eleven distinct localities, total 327,000 tonnes averaging 42.7 per cent iron (Minister of Mines Annual Report 1956, page 133). The deposit is similar and adjacent to the Rob Roy deposit (092E 015).

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 on the previous mapping and sampling programs. In 1984, Homestake Canada completed a program of geological mapping and rock sampling. In 1987, Great Keppel Resources completed a program of geological mapping, geochemical sampling, hand trenching and a ground magnetic survey. In 1988, Centaur Resources completed a program of geological mapping and geochemical sampling. 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 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. In 2014 Pioneer Exploration Corp. on behalf of Canadian Dehua completed GPS grid-based geological mapping, soil and stream moss mat geochemistry and ground magnetics covering the Glengarry past producer, and the Rob Roy and Head Bay prospects; and limited prospecting and stream moss mat geochemistry near the Vivian prospect. In the Glengarry West Grid area, stream moss mat samples yielded up to 0.61 ppm gold and 462 ppm zinc; soil samples yielded up to 0.306 ppm gold, 3.97 ppm silver, 287 ppm arsenic, 3.01 ppm bismuth, 21.6 ppm cadmium, 171 ppm cobalt, 845 ppm copper, 12.6 ppm molybdenum, 294 ppm lead, 1.22 ppm tellurium and 3020 ppm zinc; rock samples yielded up to 2.72 ppm gold, 4.03 ppm silver, 342 ppm arsenic, 28.4 ppm bismuth, 132 ppm cobalt, 2960 ppm copper, 552 ppm zinc and 89.8% magnetite; and ground magnetic established 9 Fe/Cu/Zn Skarn target areas in 5 clusters.
