The Y 46 showing is located 5.5 kilometres east of the Similkameen River and 18.5 kilometres south-southeast of Princeton.

The area is underlain by the eastern facies of the Upper Triassic Nicola Group consisting of mafic augite and hornblende porphyritic pyroclastics and flows.

Mineralized outcrops of Nicola Group volcanics are exposed at the headwaters of Wolfe Creek. The volcanics exhibit chloritic and "feldspathic" (potassic?) alteration and contain 1 to 2 per cent pyrite, with traces of chalcopyrite. Similarly mineralized and altered outcrops occur 1 kilometre west-southwest of this showing at grid coordinates 70 South, 16 East (Assessment Report 3188).

In 1971, Coin Canyon Mines completed a program of soil sampling and ground magnetometer and induced polarization surveys on the area as the Y claims. During 1991 through 1994, G.F. Crooker completed programs of silt sampling, geological mapping and ground geophysical surveys on the area as the Tas 1-2 claims. In 1996, Moreleigh Minerals completed a program of geological mapping, soil and rock sampling and ground electromagnetic and magnetic surveys. In 2009 through 2011, Supreme Resources completed programs of geochemical sampling and a 19.5 kilometre induced polarization survey.
