The Humphrey occurrence is located northwest of Humphrey Lake, approximately 20 kilometres northeast of Takla Landing.
A major structural feature, the Vital fault, strikes north-northwest and dips east through the area, dividing metasediments and greenstone of the Carboniferous to Jurassic Cache Creek Complex to the east and serpentinite and ultramafic rocks (peridotite and harzburgite) formerly assigned to the Middle Permian to Late Triassic Trembleur intrusions and now termed Mississippian to Triassic Oceanic Ultramafites, to the west. The ultramafics are variably serpentinized and have locally undergone quartz-carbonate alteration, resulting in generally lenticular zones of quartz- ankerite-mariposite. The alteration zones are cream to light brown, weather orange-brown and are most prominent adjacent to the main fault (Assessment Report 14554).
Serpentinite in the area is described as massive, widely sheared and hosts talc and chrysotile veinlets together with coarsely crystalline actinolite and tremolite (Assessment Report 12548, page 4).
In 1983, Golden Porphyrite Ltd. completed an exploration program on the property containing the occurrence. Geochemical surveys outlined significant gold anomalous zones from rock chip and soil samples. Anomalous silver was observed in two areas of the property.
In 1985, Beauty Geological Ltd. completed geological and geochemical surveys on the property containing the occurrence. Anomalous gold and silver was observed in results.
In 1987, Eric Shaede and Lorne Warren completed a prospecting program on the Gold claim group approximately 1200 metres southeast of the occurrence. Soil and rock sampling yielded maximum values of 38.2 grams per tonne gold in sampling lines and a maximum value of 59.1 grams per tonne gold in tailings sampling (Assessment Report 17298).
In 2015, Jedway Enterprises Ltd. completed a prospecting program on the Den property containing the occurrence. Rocks with nephrite potential in four locations on the property were described and reported. Follow-up prospecting for jade potential was recommended.
