The BETH showing is located on the OUTBACK property in the Granby River valley, approximately 25.5 kilometres west-southwest of the village of Edgewood.
The general area is underlain by gneiss of the Proterozoic Monashee Complex. Within the Granby River valley there is a north trending, easterly dipping normal fault, along which andesite of the Eocene Marron Formation (Penticton Group) is preserved. Co-magmatic with the Marron Formation are Eocene Coryell Intrusions which form small isolated intrusions throughout the area. The Coryell Intrusions are largely syenitic in composition, although a quartz-feldspar porphyry found 500 metres to the northwest may be a calc-alkaline variation. A quartz monzonite intrusion, which hosts the BETH showing, may be an unnamed Middle Jurassic intrusion.
Mineralization in the BETH showing consists of a stockwork of hairline to centimetre sized, milky-white, sugary chalcedonic quartz veinlets in a propylitic and argillically altered quartz monzonite. Silica deposition has most commonly occurred as open-space fracture fillings leaving vuggy, drusy quartz veins. Vein centres often display narrow cavities with fine aggregates of hexagonal quartz and bladed calcite. Epithermal-style colloform, crustiform, vuggy cavities and finely banded textures suggest multiple phases of veining. Vein selvages are distinctly banded and composed of fine sericite, chlorite, minor pyrite and pinkish, grey, potassic feldspar.
The OUTBACK property, which includes the BETH showing, was staked in 1988-89 by the Canadian Nickel Company Limited (INCO). INCO carried out several field programs of stream sediment sampling, follow-up prospecting, soil sampling and geological mapping in 1989. The gold potential of this area was identified through the use of heavy mineral stream sediment techniques.
In 1990, INCO carried out detailed soil sampling, prospecting, geological mapping and extensive rock sampling on a number of gold- silver occurrences in this area, including the nearby CLIFF (082ENE067), LEAH (082ENE069), JANE (082ENE070), and TARA (082ENE071) occurrences. A 0.4-metre channel sample of a quartz-adularia stockwork from the BETH showing assayed 0.515 gram per tonne gold and 13.8 grams per tonne silver (Assessment Report 21032).
In 1991, INCO carried out a 6-hole, 807.1-metre diamond-drill program on the CLIFF (082ENE067) prospect 500 metres to the northwest. A number of drill intersections assayed greater than 0.5 grams per tonne gold (Assessment Report 21916). The drill program resulted in the re-interpretation of the CLIFF prospect as a porphyry-gold deposit type, partly because of the association between gold-silver bearing quartz stockworks and a quartz-feldspar porphyry intrusion. It is not recorded if this intrusion has been identified at the BETH showing.
