The Elnora occurrence is located on Piggott Creek, approximately 7 kilometres south of its junction with the Oyster River and at an elevation of about 640 metres.

The area is underlain by block faulted Upper Triassic Karmutsen Formation volcanics (Vancouver Group) which are unconformably overlain by Upper Cretaceous Comox Formation sediments (Nanaimo Group). The Karmutsen rocks consist of very gently dipping thick amygdaloidal basaltic flows with interbedded pillow lavas, pillow breccias and very minor intercalated tuffaceous beds. The Comox rocks are composed of fairly flat lying conglomerates and sandstones with interbedded siltstone and shale. Tertiary intrusions disrupt the strata to the east of the occurrence area.

The Elnora vein conforms to bedding, is sheared and overlain by gently flexed Karmutsen volcanics. The showing is a siliceous (drusy quartz), carbonatized (ankeritic) breccia at least 0.6 metres thick. It is mineralized with 1 to 2 centimetre wide pods of galena and sphalerite, with lesser amounts of chalcopyrite, anglesite and tetrahedrite, along with traces of tennantite, argentite, covellite and native silver.

In 1984, sample (8309-1) of well mineralized quartz yielded 1667 grams per tonne silver and 4.84 grams per tonne gold. Other samples yielded up to 0.96 per cent copper, 4.85 per cent lead, 3.65 per cent zinc and 0.975 per cent molybdenum (Assessment Report 13598). In 1985, a grab sample of silicified vein assayed 110.06 grams per tonne silver, 0.41 grams per tonne gold, 0.53 per cent lead and 0.16 per cent zinc. (Assessment Report 14684). Drilling results were generally low and lacked sulphide mineralization.

In 1984 and 1985, Iron River Resources completed programs of geological mapping, geochemical sampling, prospecting and three diamond drill holes, totalling 35.1 metres. During 1986 through 1988, Noranda Exploration Company completed programs of airborne and ground geophysical surveys, geochemical surveys, geological mapping and two diamond drill holes, totalling 98.78 metres.
