The BEN showing is on a south-facing alpine ridge side above Connel Creek, a southeast flowing stream into Anderson Lake. The location is in the Bendor Range, 14 kilometres west of the hamlet of Seton Portage.

Foliated greenstone of the Upper Triassic Pioneer Formation Cadwallader Group is faulted against metasediments consisting of meta-argillite and quartzite of the Mississippian to Jurassic Bridge River Complex (Group). Trending north along the faulted contact lies a sinuous body of Permian and older serpentinized peridotite of the President Ultramafics, and diorite and granodiorite of the Cretaceous to Tertiary Bendor pluton.

Narrow, 2 to 20 centimetre wide, vuggy quartz veins trend north-northeast and crosscut all rock types. Disseminated pyrite is common and forms intense gossans in the granodiorite. All veins carry minor amounts of pyrrhotite and molybdenite. Along the north side of the periodotite-serpentinite intrusion, quartz veins carry mariposite and carbonate-talc alteration is observed. The broad and intermediate regional lineament analyses show that the property is located proximal to major regional structures and that smaller, conjugate linears are observed to branch off the major features (Assessment Report 39079).

In 1980 and 1981, Dupont of Canada Exploration Ltd. conducted programs of prospecting, geological mapping, rock, soil and stream sediment sampling. Soil values up to 0.9 grams per tonne gold and stream sediment values up to 2 grams per tonne gold were obtained (Assessment Reports 9259, 9926). In 1987, two heavy mineral stream sediment samples collected by British Lion Mines Ltd., produced values of 1.0 and 7.0 grams per tonne gold in coarse fractions (Assessment Report 17240).

In 2020, S. Boughey conducted a structural photo interpretation of the Ben showing area.
