The Ridge developed prospect is a distinct northeast trending silicified spine structure, located 4.4 kilometres east from the summit of Alberts Hump, south of Abesti Creek, and 650 metres east from the Bonanza occurrence (094E 079). It lies within the Omineca-Cassiar Mountains in the west-central portion of the Toodoggone Gold Camp. Smithers is approximately 300 kilometres to the south.

The occurrence 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.

The Ridge prospect is a distinct northeast trending silicified spine structure which has been traced for over 700 metres. The structure is 5.4 metres wide, 106.6 metres long and extends 213.3 metres downdip. Hostrocks are predominantly andesitic flows, tuffs, and affiliated breccias. A dacitic ash flow is locally present. Crosscutting and longitudinal faults displace the Ridge structure both vertically and horizontally. The structure appears to pinch out in the northeast; however, a fault may have offset this segment. In the southernmost exposures, a segment of the probable Ridge structure is displaced 100 metres to the southeast.

The silica/clay alteration assemblage of rocks hosting the gold-silver mineralization appears in single or multiple and branching bands. Minor late barite-hematite veinlets are present but are non-metalliferous. Alteration widths of intense argillization and silicification vary from 5 to 30 metres. The mineralized zones, which contain pyrite (and galena), appear to be roughly lensoidal and very discontinuous (Bulletin 86). The multiphased silicified and hematized structure has a highly erratic distribution of gold and silver. The average gold grade is lower and silver grades are generally higher than those typically found in the Thesis III (094E 091), BV (094E 099) and Bonanza occurrences.

Drillholes A87-101 and 102, part of a widely spaced drill and trench program, indicate that the structure contains ore shoots (Assessment Report 17655). Assay results from these drillholes are as follows: drillhole A87-101 yielded a weighted average of 4.3 grams per tonne gold over the 5.0-metre interval from 79.35 to 84.35 metres and 24.0 grams per tonne gold over the 11.0-metre interval from 87.35 to 98.35 metres (Assessment Report 17655); drillhole A87-102 yielded a weighted average of 9.1 grams per tonne gold over the 1.5-metre interval from 159.25 to 160.75 metres, and 6.2 grams per tonne gold over the 4.72-metre interval from 176.25 to 181.66 metres (Assessment Report 17655).

The Ridge structure may be truncated by a fault at its northeast end, beyond where it has been tested by trenching and drilling. At its southwest end, fault offset segments 50 metres to the northwest (the Shark zone) and 170 metres to the southeast (the South Ridge zone) have been identified by trenching. Trench TA86-109 across the South Ridge zone exposed a mineralized interval grading 2.10 grams per tonne gold across 16.2 metres (Bowen, 2012). It is reported that this zone appears to have not been drill tested.

By 2012, it was reported that at the Ridge, 2203.8 metres were drilled in 16 holes.

Micromine's 2007 resource estimate for the Ridge zone, using "uncut" gold assays and a cut-off grade of 3.5 grams per tonne gold, is 52,480 tonnes grading 4.12 grams per tonne gold (Bowen, 2012). There are no other comparative historical resource estimates available that might validate this estimate, which is not National Instrument (NI) 43-101 compliant.

See Bonanza (094E 079) for details of the Ranch (Al) property which presently contains the Ridge prospect and discusses the work done on it.
