The Ring occurrence is located 3.8 kilometres southeast of the summit of Alberts Hump, south of Abesti Creek and 900 metres southeast of the BV (094E 099), approximately 300 kilometres north of Smithers. It lies within the Omineca-Cassiar Mountains in the west-central portion of the Toodoggone Gold Camp.

The Ring showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The Adoogacho and Metsantan members of the Toodoggone Formation underlie the AL property. 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 with it. For a more detailed account of the local geology and alteration refer to the AL (Bonanza) occurrence (094E 079).

The Ring showing comprises an extensive area of argillic to siliceous alteration 600 metres long and at least 300 metres wide. The dominant alteration is silicification and silicification-argillization. There appear to be two fracture trends, southeast and north-northeast. The north-northeast trend is siliceous and is the trend of all primary features using silicified zones as indicators. Typically, the silicified zones within the AL (Ring) showing are composed of cryptocrystalline quartz with considerable limonite on fracture planes and as vug fillings. Outcrops are heavily brecciated and fractured; individual fragments show crude banding and barite is rare. The southeast trend is argillized and trenching indicates that this alteration is the most important and widespread of the two alteration types. The argillized rocks comprising the bulk of the zone are porphyritic and slightly siliceous. Local sections contain hematite and limonite is abundant.

Gold mineralization is restricted to zones of strong silicification containing little or no clay, typical of other occurrences on the AL property. A grab sample (B323) from silicified outcrop in Trench 13 assayed 1.6 grams per tonne gold (Assessment Report 14460).

A 1981 surface grab sample taken by Kidd Creek (formerly Texas Gulf) assayed 14.74 grams per tonne gold (Bowen, 2012).

Trenching by Energex Minerals Ltd. in 1985 showed that the gold values in the silicified zones are generally low, averaging about 0.25 gram per tonne; a grab sample of silicified rock taken from a trench in the southeastern part of the zone yielded 1.6 grams per tonne gold (Bowen, 2012).

In 2006, in the southernmost trench at this location at an elevation of about 1460 metres, free gold was observed in a loose sample of silica-altered andesite. Subsequent to this find, rock chip samples were collected from this location as well as several other trenches in the area. A high of 0.45 gram per tonne gold was obtained (Assessment Report 28887). However, the fact that free gold was identified indicates that only large, bulk samples from this area will provide an accurate result. It is believed that free gold had not previously been reported from this area.

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 BBX area (094E 193). 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 Ring showing, and several other prospects.
