The Ray occurrence is located on a south-southwest–facing slope of a moderate sized hill, approximately 1.2 kilometres north-northeast of the east end of Naltesby Lake.

The region is underlain to the west by the Mississippian to Triassic Cache Creek terrane and to the east by the Quesnellia Terrane and the Omineca Belt. Younger volcanic and sedimentary rocks of Middle Jurassic and Tertiary age overlie the Cache Creek Group. The boundary between the Quesnellia Terrane and the Cache Creek Terrane is probably the southern extension of the Pinchi fault system.

Tectonically emplaced within the Cache Creek Group are ultra- mafic rocks of ophiolitic affinity which are now variably deformed and metamorphosed.

The Ray showing is underlain by one of these ultramafic bodies which, here, is composed of dark green, variably serpentinized peridotite. Small occurrences of cross fibre asbestos with fibres up to 1.3 centimetres long are found in widely spaced veinlets. These veinlets also have associated nickel silicate mineralization.

Work History

During 1967 through 1970, Enbrook Mines Ltd. completed program of soil sampling, trenching, five diamond drill holes and a 22.4 line-kilometre ground magnetic survey on the area as the Ray claims. Drilling is reported to have yielded up to 0.38 per cent nickel in a silicate form (Assessment Report 2557).

In 1982, Campbell Resources Inc. completed a program of soil and heavy mineral sampling on the area as the Bobtail claim. Heavy mineral concentrate samples yielded up to 5.28 grams per tonne gold (Assessment Report 10828).

In 1986, Mascot Gold Mines Ltd. completed a program of geological mapping and geochemical (rock, soil and heavy mineral) sampling on the area. Heavy mineral concentrate samples yielded up to 6.55 grams per tonne gold (Assessment Report 15160).

In 2010 and 2011, Porpoise Bay Minerals Ltd. completed programs of geological mapping and geochemical (rock, silt and soil) sampling on the area as the BT 1-17 claims of the Bobtail property. Rock samples were reported to have yielded from 0.115 to 0.320 per cent nickel and up to 0.314 per cent chromium with an average of 0.205 per cent nickel from 53 samples (Assessment Report 32797).

During 2014 through 2017, Porpoise Bay Minerals Ltd. completed programs of test pitting, trenching and geochemical (rock, silt and soil) sampling on the property. This work identified an outcrop of granitic intrusive hosting quartz veins and stringers with pyrite and chalcopyrite located approximately 15 kilometres to the north of the Ray occurrence.
