The Richter showing is located 2 kilometres east of Richter pass and 3.0 kilometres north of Blue Lake near Richter Pass. Osoyoos is 8 kilometres to the southeast. The showing is covered by the Richter claims, owned and operated in 1984 by P. Peto.

The Richter occurrence lies within granodiorite and diorite of the Middle Jurassic Similkameen intrusions which have intruded quartzite, schist and greenstone rocks of the Carboniferous to Permian Kobau Group. To the north and east, the Kobau rocks are exposed. To the south, syenitic rocks of the Jurassic Kruger pluton occur. Fissuring, shearing and fracturing of andesite and other volcanic rocks on the property is extensive and is possibly related to the northwest trending Blue Lake fault.

During property exploration in 1984, rock samples were taken from silicified outcrops within a rusty shear zone in altered granite. The best sample, 51261, yielded 1.4 grams per tonne silver, 0.30 gram per tonne gold and 0.03 per cent copper (Assessment Report 13217).
