The Ant occurrence is located at the southern end of a ridge, 7.5 kilometres south-southeast of Tuff Peak and 4.2 kilometres east-northeast of the Mets prospect (094E 093), approximately 305 kilometres north of Smithers. The showing lies within the Omineca-Cassiar mountains in the west-central portion of the Toodoggone Gold Camp.

The 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. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite 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 Ant showing is underlain by volcanics of the Attycelley Member of the Toodoggone Formation. At this showing these consist of varieties of feldspar, hornblende, and biotite porphyries of andesite to dacite composition; crystal-lithic tuffs and lapilli tuffs, massive flows, chaotic breccias and lahar of rhyolitic composition, and conglomerate, sandstone, mudstone and dikes (Assessment Report 15257). The showing lies between two of four north-northwest trending faults transecting the area around the Ant showing.

At the Ant showing, a stockwork consisting of numerous quartz and calcite veinlets, often brecciated and cemented with quartz and calcite, occurs in porphyritic dacite. No sulphides are reported from this alteration zone. Rock chip samples taken from this zone in 1982 did not yield any anomalous values. Sample 5023C analyzed 0.005 gram per tonne gold and 0.9 gram per tonne silver (Assessment Report 10473). Subsequent resampling from this zone (sample 85PS79R) in 1985 did, however, analyze 0.200 gram per tonne gold and 26.6 grams per tonne silver (Assessment Report 15257).

The area was prospected and sampled by Tom Richards for Mandusa Resources Ltd. in 1985 and for Alpine Exploration Corporation in 1995. The area was sampled by Henry Marsden for Paget Resources Corporation in 2006.
