The Blue occurrence is located in the southern head waters of Waukwaas Creek, approximately 6.5 kilometres south east of Sarah Lake.

The area is underlain by the Upper Triassic Vancouver Group, Karmutsen Formation which is comprised mainly of a thick sequence of tholeiitic basalts. Regional north and northeast trending faults crosscut the volcanics (Geological Survey of Canada Map 4-1974).

Disseminated chalcopyrite and bornite mineralization are reported to occur in andesite and basalt of the Karmutsen Formation. The mineralization is localized in the southeast corner of the Blue 3 claim and about 1.0 kilometre to the east, on the far east side of the Blue 2 claim (Assessment Report 1662).

In 1968, Alpha Mines completed a program of soil sampling and prospecting on the area as the Blue claims.
