The Alpeer showing is located on the upper northern slope of Cats Ears Creek.

The area is underlain by intermediate and mafic volcanics of the Upper Triassic Karmutsen Formation (Vancouver Group) of are intruded by granitic to dioritic stocks of the Middle to Upper Jurassic Island Plutonic Suite. At the Alpeer occurrence, andesites and rhyodacites are in fault contact with granodiorite to diorite rocks.

The volcanics host seams and fracture fillings containing quartz, epidote, limonite, pyrite and minor arsenopyrite, sphalerite, galena and chalcopyrite. The volcanics also contain abundant disseminated pyrite and are silicified and intensely chloritized.

In 1987, a 2 metre chip sample of intensely sheared rhyodacite with abundant pyrite and limonite assayed 45.7 grams per tonne gold (Assessment Report 16252). The gold which is associated with the pyrite is fairly coarse-grained. In 1997, sampling reported 2101 parts per billion gold, (Assessment Report 25322). In 2009, grab samples of altered basalt hosting sulphide veins assayed up to 12.7 grams per tonne gold (Assessment Report 31247).

A sample of a quartz vein, located 200 metres southwest of the anomalous gold sample, contained 0.7 per cent copper and 1.05 grams per tonne gold (Assessment Report 16252). The vein, 5 to 10 centimetres wide, contains abundant pyrite and minor arsenopyrite, chalcopyrite and sphalerite.

In 1971 and 1972, Mount Washington Copper Company and Phelps Dodge completed programs of soil geochemical surveys which outlined several copper anomalies. The property was re-staked in 1982 and optioned to Placer Development Limited in 1984. In 1985, a limited program of geophysical and geochemical surveys identified five zones of anomalous gold content in soils. In 1987, the property was optioned by Acquest Enterprises and an exploration program of rock chip sampling was completed. Between 1994 and 1997, the property was prospected by R. McGreevy and resulted in the discovery of the VER and VER PMC showings to the east. In 2009 through 2011, Electrum Resources completed program of geochemical sampling and geological mapping on the area as the Lucky 18 claim, apart of Lucky property.
