The Ridge showing is located at about 1855 metres, 2.75 kilometres north of Mount Kobau. The showing was located during exploration of the Richter claim group by Minnova Inc. in 1990.

Regionally, the Ridge showing is hosted by polydeformed regionally metamorphosed sedimentary and volcanic rocks of the Carboniferous to Permian Kobau Group. The aerial distribution of Kobau Group rocks is restricted by the Similkameen River to the west and the Okanagan fault to the east. These rocks have been affected by regional metamorphism reaching greenschist grade, thought to have been attained during the first phase of regional deformation. The Similkameen plutonic complex is located 1.5 kilometres to the southwest. Granodiorite plugs of the Jurassic to Cretaceous Fairview intrusion occur in the area.

The Kobau Group rocks have been subdivided into up to three main units; generally consisting of quartzite, phyllite and calcareous phyllite. The Kobau Group rocks have a northwest trending schistosity as well as a major northwest trending fold axis.

The Ridge showing consists of a gossan along the contact of Kobau Group rocks with a plug of Fairview granodiorite. Silicification is intense and quartz veins are common along this contact. The quartz veins are 1 to 5 centimetres wide, lack visible sulphides and form a stockwork. Alteration and quartz veining are generally related to fault structures. Sample RG138 from a quartz vein in the gossan yielded 2.2 grams per tonne gold and 0.4 gram per tonne silver (Assessment Report 19284).
