The Ant occurrence is located approximately 2.5 kilometres south of Wade Lake, about 75 kilometres east-southeast of the community of Dease Lake.

The Ant showing area is underlain by banded limestone of the Upper Triassic Sinwa Formation which strikes 037 degrees and dips 50 degrees southeast. Volcanic rocks in the area are a mixture of flows and ejecta mainly of andesitic composition. Some of the rocks are altered to chloritized and serpentinized schists. These rocks may belong to the upper Permian to Lower Triassic Kutcho assemblage. The Sinwa Formation has recently been reassigned to the Stuhini Group (Stikine Terrane). See Kutcho Creek deposit (104I 060) for details on the new age date for the Kutcho assemblage.

Trenches expose veins of quartz and calcite with chalcopyrite and minor amounts of pyrite. The mineralized zone is conformable with bedding and the "horizontal exposure" is reported to be 3 metres at one locality but narrowing along strike (Assessment Report 437). It is traceable through three trenches for a length of 24 metres. The veins are reported to be associated with schist but limestone appears to be the main host lithology. Minor amounts of sphalerite and pyrrhotite are also found in limestone nearby.

Julian Mining Co. Ltd. explored the Ant group (Ant and TNA claims) in 1962 and 1965. Geological mapping was carried out in both years and a geochemical survey was made in 1965. The 1965 work was not published.
