The D'ARCY NEPHRITE occurrence is located approximately 1.5 kilometres north-northwest of the village of D'Arcy at the south end of Anderson Lake.
Nephrite is found in small lenses along the deformed contact between sheared gabbroic and dioritic intrusive rocks and underlying undeformed dunite. The area is underlain by sediments and volcanics of the Upper Triassic Hurley Formation, Cadwallader Group and Mississippian to Jurassic sediments and volcanics of the Bridge River Complex (Group). The serpentinite may be related to the Permian Bralorne-East-Liza Ultramafic Complex (Chism Creek Schist) or the Shulaps Ultramafic Complex.
The widest band is 50 centimetres in a zone trending northwest for 150 metres. The grade is not high; it is termed "semi-nephrite" and contains much shredded tremolite. Fractured chromite grains within the nephrite are partly replaced by chlorite, giving the soapstone a spotted green appearance. Clinozoisite is present in the alteration zone and minor amounts of prismatic tremolite and diopside are present.
The property has been explored for carving stone since 1974, but no exploration has been recorded. The property is referred to in the 1983 X-Calibre Resources Ltd.'s report on the gold potential of the area (Assessment Report 11749). In 2019, D. Bridge conducted magnetic susceptibility and resistivity measurements on the host rocks in an attempt to target the more sought-after green-spotted soapstone (Assessment Report 38596).
