The Ruby occurrence is located 33 kilometres north of the town of Alice Arm, on the east bank of the Kitsault River. A pyritic quartz vein was explored here between 1919 and 1921.

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 Ruby showing consists of a quartz vein in sheared andesitic breccia and greenstone (andesite) of the Hazelton Group. The vein is 1.2 to 2.4 metres wide and has been traced by trenching for 107 metres. The vein is concordant to the enclosing rocks, which strike northwest and dip southwest on the east limb of the Kitsault River syncline. Mineralization consists of sparse pyrite with a trace of galena.

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.

In 2017, Dolly Varden Silver Corporation announced plans for 12,000 metres of diamond drilling at the Dolly Varden silver project. The project consists of the Torbrit (103P 191), Dolly Varden (103P 188), Wolf (103P 198), and North Star (103P 189) deposits. Drilling between the Torbrit and Wolf deposits resulted in a new discovery (Central zone), with results that included 16.10 metres (13.19 metres true thickness) grading 269.0 grams per tonne silver, 0.30 per cent lead and 0.21 per cent zinc. Follow-up drilling confirmed this discovery, returning results of 7.15 metres (6.72 metres true thickness) grading 1180.7 grams per tonne silver, 1.83 per cent lead and 0.26 per cent zinc. Drilling also discovered an eastern fault offset of the Torbrit deposit (Torbrit East, 103P 190), with assays including 13.00 metres (9.96 metres true thickness) grading 244.8 grams per tonne silver, 0.14 per cent lead and 0.09 per cent zinc. Within this interval was 5.00 metres (3.83 metres true thickness) grading 481.9 grams per tonne silver, 0.21 per cent lead and 0.12 per cent zinc (Information Circular 2018-1, page 137).
