The Rubinca (Bouleau Lake) mine is located on the north side of Bouleau Lake, approximately 27 kilometres west of Vernon.

Regionally the area is underlain by volcanics, mudstone, siltstone, shale and fine clastic sedimentary rocks of the Devonian to Triassic Harper Ranch and(?) Nicola groups, which are intruded by Middle Jurassic granitic rocks. Volcanic rocks of the Eocene Penticton and Kamloops groups overlie the older units.

Locally, Kamloops and/or Penticton Group feldspar-porphyry andesite flows host jasper and agate (Personal Communication - R. Gay, Vernon).

In 1985, Chevron Canada Resources Ltd. prospected and soil sampled the area as the Vodd 1-8 claims. In 1988 and 1989, furthers program of rock, silt and soil sampling were completed on the area as the Beulah and Vodd claims. These programs were directed towards identifying gold-silver mineralization.

In 1995, the area to the north was prospected and sampled as the Annie Bell claims. This work identified at least six vertical seams, varying from 5 to 25 centimetres in width, of black to dark-brown opaque chalcedony and yellow-brown to milky agate along the Bouleau Forest road.
