The Ranger (Ben d’Or) occurrence is located on the southeast- facing slope of an unnamed peak located 7 kilometres east-southeast of the community of Gold Bridge in the Bendor Range.

The area is underlain by Mississippian to Jurassic Bridge River Complex (Group) siliceous cherty sediments, argillites, limestones and volcanics. This package is intruded by granodiorite plugs of the Cretaceous to Tertiary Bendor pluton and also contains masses of serpentinite. Porphyritic dykes, probably Tertiary, also cut these rocks.

Locally, a number of zones host mineralized quartz and calcite veins occurring in northwest- trending shears and fractures in silicified and pyritic chert.

The "Ben d’Or" (Adit zone) vein is approximately 30 centimetres wide and contains massive tetrahedrite and arsenopyrite and minor amounts of galena, sphalerite, stibnite, chalcopyrite and pyrite. Alteration minerals include limonite, stibiconite, sericite and ankerite.

It is reported that, in 1944, sulphide-rich (arsenopyrite and pyrite) portions of the vein assayed up to 153.4 grams per tonne gold and 258.0 grams per tonne silver over 0.3 metre, while a 0.66 metre section of adjacent wall rock yielded 13.8 grams per tonne gold and 58.5 grams per tonne silver (Assessment Report 12416). In 1983, a dump sample (No. 00910) assayed 0.452 per cent lead, 0.262 per cent cobalt, 0.112 per cent antimony, 0.139 per cent bismuth, 53.5 grams per tonne gold and 50.0 grams per tonne silver (Assessment Report 12416). In 1984, a chip sample (No. 4702), taken across 0.3 metre, yielded 0.395 per cent lead, 0.130 per cent antimony, 124.0 grams per tonne silver and 61.1 grams per tonne gold (Assessment Report 14225).

The Saddle (Moore cut) zone, consisting of several pits and located 200 metres northwest of the Adit (Ben d’Or) zone, has narrow veinlets with similar mineralization to the main vein (tetrahedrite, arsenopyrite and stibnite) and is also hosted in fractured cherts containing tourmaline. In 1984, a grab sample assayed 1.63 grams per tonne gold and 18.8 grams per tonne silver (Assessment Report 14225).

The South zone, located few hundred metres to the south of the adit, consists of basalts hosting an arsenopyrite vein. In 1983, a chip sample (00959) yielded 0.675 gram per tonne gold, 30.0 grams per tonne silver and 1.00 per cent copper over 2.5 metres (Assessment Report 12416).

The East Ridge zone, located 1000 metres north east of the adit, has anomalous gold, silver, zinc and arsenic soil geochemistry. The area is underlain by silicified cherts, andesites and a thin (2 metre) quartz-carbonate horizon. Several old trenches are noted in the area.

Also reported on the property are limestones, which are skarn-altered and contain chlorite, actinolite, pyrite, pyrrhotite and limonite, as well as quartz-carbonate-mariposite (listwanite) assemblages representing altered ultramafics.

The area was originally staked in 1944 as the Ben d‘Or claim. The same year, Bralorne Mines optioned the property and explored the main (Ben d’Or) vein with an adit for a distance of approximately 8 to 12 metres. The following year, three diamond drill holes, totalling 62 metres, were completed. In 1975, a program of rock sampling, trenching and a ground magnetometer survey were completed on the area as the Bee claims. In 1981, a program of airborne geophysical surveys was completed on the area. In 1983 and 1984, Newmont completed programs of rock, silt and soil sampling and geological mapping on the area as the Ranger 1-4 claims. During 1985 through 1988, Levon Resources completed programs of trenching, rock and soil sampling and airborne geophysical surveys on the area.
