The Ruby showing is situated on the north bank of the Similkameen River, 1.2 kilometres northwest of Hedley.
Various small stocks, dykes and sills of hornblende diorite and gabbro of the Early Jurassic Hedley Intrusions intrude thin-bedded siltstone, argillite and limestone of the Upper Triassic Stemwinder Mountain Formation (Nicola Group). Limestone beds are weakly to moderately altered to fine-grained garnet diopside skarn adjacent to the Hedley Intrusions.
The skarn zones are mineralized with disseminated pyrite, pyrrhotite and arsenopyrite. A sample of such skarn taken near a collapsed adit assayed 2.3 grams per tonne gold (Assessment Report 17785, page 4, sample 5424).
