The CU 17-20 occurrence is located southeast of a small lake in the southern Highland Valley, approximately 1.5 kilometres east-southeast of Gnawed Mountain.

The area is in the central core of the Lower Jurassic Guichon Creek Batholith. The area is underlain primarily by Skeena variety granodiorite and quartz diorite, which has textures and compositions intermediate between those of the older Bethlehem phase rock to the north and east and those of the younger Bethsaida phase rocks to the southwest. The Skeena rocks are intruded by north trending Bethsaida porphyritic granodiorite dikes. Fine-grained aplite dikes are common.

Locally, drilling has identified molybdenite and minor bornite mineralization in a Bethlehem quartz diorite. Alteration minerals included sericite, epidote, potassium feldspar and chlorite.

In 1972, a drill hole (S-72-7) yielded 0.127 and 0.241 per cent molybdenum over 15 metres, respectively (Property File - Doug [1973-01-08]: Re: Sheba Drill Holes).

Work History

In 1958, Sheba Copper Mines completed a program of geochemical sampling and an induced polarization survey on the area as the Sheba property.

In 1965, Anaconda American Brass completed six drill holes on the Jay 101 area. In 1967, Sheba completed a 67.2 line-kilometre induced polarization survey, while Sumitomo Metal was reported to have completed 15 diamond drill holes, totalling 1970.7 metres, and 21 percussion drill holes, totalling 1574 metres on the property. In 1969, Anaconda is reported to have completed seven diamond drill holes, totalling 1564.2 metres, on the property.

During 1971 through 1974, Dowa is reported to have completed 36 diamond drill holes, totalling 7830.6 metres, on the property. In 1974, Sheba completed three diamond drill holes, totalling 636.0 metres, on the Lynn 7, J 4 and J 6 claims. In 1976, Western Mines Ltd. completed 61 percussion drill holes, totalling 3518.0 metres, on the property. In 1977, Bethlehem Copper Corp. completed four diamond drill holes, totalling 953.1 metres, on the Sheba East area.

In 1984, Cominco Ltd. completed an induced polarization survey on the area.

During 2018 through 2020, Mascot Capital Inc. completed programs of prospecting, geochemical (rock and soil) sampling, 3D compilations of historic magnetic data and an 8.0 line-kilometre seismic survey on the area as the Gnawed Mountain property.
