The EC 60 occurrences are located about 800 metres north of Long Island Lake (which is known locally and on some old maps as Janice Lake), which is about 15 kilometres northwest of Little Fort. The mineralization consists of small sulphide lenses in a 15 to 18 metre wide zone of skarny alteration that parallels the bedding in the enclosing dark grey calcareous shale and siltstone of the Upper Triassic Nicola Group. Bedding dips steeply to the west-southwest and is intruded by a 10 metre wide sill of sericitized and weakly mineralized quartz-feldspar porphyry directly east of the mineralized zone. The sulphides include pyrrhotite, pyrite and galena, locally accompanied by minor amounts of chalcopyrite and sphalerite (Fieldwork 2000). Another occurrence about two kilometres east-southeast consists of disseminated and fracture fillings of pyrite and chalcopyrite in sediments and volcanic rocks. In some reports this is treated as a separate occurrence called the Jan or the Janice Lake showing (Assessment Report 26223; Minister of Mines Annual Report 1967).

In 1967, Royal Canadian Ventures Limited conducted assessment work on the EC property, most of which existed south of the Long Island Lake property, which included 739 heavy mineral samples, 323 silt samples and 592 soil samples. Royal Canadian reported that some trenching and diamond drilling had been done on this showing prior to 1967 by different owners. A follow-up induced polarization survey was done by Royal Canadian on the EC claims in 1968. Teck Exploration conducted assessment work on the Haida property, (including the EC 60 showing on the Vit 4 claim) in 1989 and 1990. The area was included in the Deer Lake property by Electrum Resource Corporation when they conducted geochemical and geological work in 1999.
