The ELK 7 showing is located on the east shore of the southernmost of the Arlington Lakes, across from Lakevale.

This area was intensively explored in the early part of this century, especially during the period 1910-13 when the Kettle Valley Railway was built. In 1970, Durocop Mines Ltd. prospected the general area around the ELK 7 showing. In 1971, Hudson's Bay Oil and Gas Ltd. carried out a magnetometer survey of the area to the south. And in 1973, K.F. Brunning funded a soil geochemical survey and geological mapping of the area.

The showing consists of several lake-shore outcrops of hornblendite and pyroxenite which contain disseminated chalcopyrite and pyrite. Magnetite is evident throughout the rock, in finely disseminated grains and bunches, in fracture fillings and in thin bands. The rocks appear to be a mafic intrusion within the Carboniferous-Permian Anarchist Group rocks, which are in contact with the Cretaceous Okanagan Batholith to the north.

The LAKEVALE (082ENW040) past producer is located on the west side of Arlington Lakes, roughly across from the ELK 7 showing.
