The Syd occurrence is located north of the head of Refuge Cove, near the western shore of Sidney Inlet.

The area is underlain by a multi-phased, 2 by 17 kilometre Eocene Catface Intrusion that consists of a leucocratic quartz- diorite phase and a biotite-hornblende diorite phase. The latter phase contains kaolinite-altered plagioclase, and less than 10 per cent quartz.

Mineralization is associated with a series of joints trending 330 degrees and dipping 70 degrees east. Secondary biotite and hornblende are concentrated along the joints. Disseminated chalcopyrite, bornite and molybdenite occur near the fractures but decrease rapidly away from them. Surface showings are reported to extend for over 200 metres. In 1972, a hole drilled 300 metres to the north on a possible extension of the same zone intercepted 30 metres of 0.25 per cent copper (Assessment Report 4402).

In 1970, Cerro Mining Co. of Canada Ltd. completed a program of soil and silt sampling. In 1972, an unknown amount of diamond drilling was completed. In 1973, Western Mines completed an induced polarization survey on the area.
