The Ecila occurrence is located in the southern head waters of Waukwaas Creek, approximately 7 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 area (Geological Survey of Canada Map 4-1974).

The occurrence consists of finely disseminated magnetite and chalcopyrite, and fracture coatings of pyrite and pyrrhotite, in amygdaloidal basalt and quartz latite of the Karmutsen Formation.

In 1964, diamond drilling intersected 0.6 metres of 0.98 per cent copper in siliceous, slightly brecciated basalt. Iron content was reported as 10 per cent over 3 metres (Property File - McDougall, J.J., 1964, page 3).

In 1964, Coast Iron Explrotions completed a program of geological mapping, drilling and an airborne magnetometer survey. In 1968, Alpha Mines completed a program of soil sampling and prospecting on the area as the Blue claims.
