The Benboe occurrence is located west of Tommy Creek, approximately 4.5 kilometres south- south west of the creek mouth on Carpenter Lake.

The area is underlain by Mississippian to Jurassic Bridge River Group cherty sediments and basaltic greenstones that strike north east, dip steeply north west and are intruded by a stock of Cretaceous to Tertiary Bendor pluton granodiorite. Tertiary (?) porphyry dikes and a mafic dike also cut the metasediments.

The Benboe vein occurs along a sheared volcanic-sediment contact. The volcanics are silicified and oxidized. The quartz-carbonate vein varies from 0.3 to 1.8 metres in width and has been traced for 225 metres along strike. The vein strikes north 15 degrees and dips 45 to 55 degrees west. The vein is brecciated and vuggy, hosting minor stibnite-pyrite and trace arsenopyrite as disseminations and bands.

In 1937, a report gave assays of 12.34 grams gold per tonne and 17.14 grams silver per tonne (Minister of Mines Annual Report 1937, page F12). In 1985, sampling of four old trenches yielded values up to 16.4 grams per tonne gold over 0.95 metre true width (Assessment Report 15304).

Another area of quartz veining and/or rusty shearing hosting gold values is reported approximately 450 metres to the north. In 1985, a chip sample assayed 3.35 grams per tonne gold over 1.0 metre (Assessment Report 15304).

The area was first staked around 1933 by Benboe Deep Mines Syndicate and by 1936 a 14.6 metre adit was completed. In 1986, Fairchild Resources completed a program of rock and soil sampling, trenching, geological mapping and ground geophysical surveys on the area.
