The Bingo occurrence is located about 828 metres northwest of the AL (Thesis II/III) past producer (094E 091), approximately 297 kilometres north of Smithers.

The showing is underlain by rocks of the Lower Jurassic Toodoggone Formation (Hazelton Group). The Adoogacho and Metsantan members of the Toodoggone Formation underlie the area. The Adoogacho Member consists of trachydacite ash-flow tuff with lenses of lapilli tuff, rare marlstone and conglomerate near the base. The Metsantan Member is composed mainly of trachyandesite (latite) flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The Metsantan Member, in part, directly overlies the basal Adoogacho Member and is also in fault contact.

The Bingo showing is comprised of two parallel zones of silicification, including a strongly defined western zone 350 metres long, and a shorter, partially “blind” eastern zone. Both zones dip northeast, more shallowly at their northwest ends and more steeply at their southeast ends. Gold, silver, and copper occur with pyrite and chalcopyrite-bearing silica-altered rock. Gold grades in trenches range up to 3.3 grams per tonne gold across 4.4 metres (Bowen, 2012). Fourteen 1988 drillholes confirmed these surface indications of large amounts of low-grade silica-hosted gold mineralization; several holes also cut a narrower structure or structures 2 to 5 metres wide with grades in the 3 to 5 grams per tonne gold range, accompanied by silver and copper values up to 179 grams per tonne and 2.4 per cent, respectively (Bowen, 2102). The entire Bingo zone is strongly anomalous in copper; some individual 0.5-metre-long core sample lengths assay up to 3.92 per cent (Bowen, 2012). The silver grades at the Bingo showing are typically higher than most other zones in the vicinity. The highest silver assay from an individual 0.5-metre-long sample interval at Bingo assayed 243.0 grams per tonne in Hole 88-11 (Bowen, 2012).

Two types of silica alteration were observed in the drillholes. A narrow band of dense, grey, cherty quartz is present in almost all drill sections, in the hangingwall of a zone of more porous baritic silica. Both types contain abundant pyrite and chalcopyrite.

In 1985 and 1988, Energex Minerals Ltd worked on the Bingo prospect.

In 2007, Christopher James Gold Corp. conducted a helicopter-borne magnetic gradiometer survey consisting of 2229 line-kilometres over all historic gold deposits and MINFILE occurrences on the property, including the Bingo area. Maps completed include coloured Total Magnetic Intensity, Measured 3-D Analytic Signal, Measured Vertical Magnetic Gradient, and colour-shaded Tilt Derivative of the Total Magnetic Intensity.

See Bonanza (094E 079) for geological and work history details of the Ranch (formerly Al) property, which presently contains the Bingo, and several other prospects.
