The Blue Creek nephrite jade showing is 7.5 kilometres west- northwest of the confluence of Blue Creek and the Yalakom River. The showing is an irregular mass of nephrite up to 8 metres wide associated with a calc-silicate alteration zone within serpentinite melange of the Permian and older Shulaps Ultramafic Complex. The nephrite occurs as small pods with botryoidal morphology, together with minor clinoamphibole and vesuvianite. Contacts are not exposed and the extent of the mineralization is not known.
