The Anzus showing area is underlain mainly by volcanic rocks of the Lower to Middle Jurassic Hazelton Group. Other units nearby consist of volcanic rock of the Eocene to Oligocene Nechako Plateau Group (Endako and Ootsa Lake formations) and andesitic rock of the Late Cretaceous Kasalka Group. Quartz monzonite of the Late Cretaceous Cabin Lake pluton intrudes the stratigraphy.

Work History

In 1981, Dome Exploration (Canada) Ltd. completed an exploration program on the property containing the occurrence. Anomalous zinc, silver and gold were observed in soil samples.

In 2011, Kootenay Gold Inc (three prospectors) spent one day following up "Graham Creek", a north-northeast trending draw that was thought to be the location of historically reported high-grade float silver mineralization. Mineralization appears to be related to carbonate veins/breccias hosted by a sequence of intermediate volcanic and sedimentary rocks including some mudstone units. Galena and sphalerite occur as grains and masses in carbonate veins/gangue. Locally intense propylitic and sericitic alteration occurs. The veining/brecciation appears to be controlled by a north-northeast trending fault that is occupied by the creek. Mineralization and alteration is found across a length in excess of one kilometre.

Of the 16 samples collected only one contained appreciable silver, sample SK11-90 at 48 grams per tonne silver (Assessment Report 32526). A number of samples were anomalous in lead and zinc. Sample SK11-90 was a piece of carbonate breccia float with abundant galena and sphalerite. Sample SK11-87 was taken near or at a narrow shear in altered dacite with carbonate veins containing pyrite and galena.

In 2012, Kootenay Silver Inc. conducted a geochemical survey on the property containing the occurrence. No significant precious or base metal anomalies were found.
