At the Chuchi Tungsten showing, disseminated mineralization occurs in a fracture zone within andesite of the Middle Triassic to Lower Jurassic Takla Group at the contact of a small granitic stock. Scheelite, powellite, molybdenite and chalcopyrite is disseminated throughout the fracture zone, at least 3.65 metres in width, in silicified andesite. Two grab samples averaged 0.075 per cent WO3, 0.015 per cent MoS2, trace gold, and 24 grams per tonne silver (GSC Paper 45-9, page 15 and 19).

In 2008, Newstrike Resources Ltd. completed a diamond drilling program on the property containing the occurrence. The drilling was completed on the nearby Jean (Minfile 093N  079) occurrence.
