The Highland showings are located on Wilauks Creek on the southwestern slope of Wilauks Mountain, about 4.75 kilometres northeast of Alice Arm. Various showings were investigated sporadically in this area from 1916 to 1966.

The region is underlain by an assemblage of volcanics and sediments comprising the Upper Triassic Stuhini Group, the Lower Jurassic Hazelton Group and the Middle Jurassic to Upper Cretaceous Bowser Lake Group. This assemblage has been folded into a north-northwest trending anticline (Mount McGuire anticline) and regionally metamorphosed to greenschist facies.

The showings are contained in a sequence of graphitic argillites and interbedded conglomerates of the Stuhini Group. These are underlain, to the east, by augite porphyritic basaltic flows which are situated on the west limb of the Mount McGuire anticline.

On the east side of Wilauks Creek, a breccia zone in conglomerate contains irregular masses of quartz, calcite, barite and sphalerite. The zone strikes northeast, varies from 1 to 6 metres wide, and has been partially traced for 120 metres by five trenches.

A fault zone of similar strike, 100 metres to the northwest on the west side of the creek, is developed in argillite. The zone contains lenticular and irregular bodies of quartz, calcite, sphalerite and minor pyrite and galena. A 3.0 metre chip sample taken across the zone assayed trace gold, 13.7 grams per tonne silver, trace lead and 2.5 per cent zinc (Minister of Mines Annual Report 1927, page 73). Farther upstream, a 1.5 to 6.1 metre wide zone in argillite is mineralized with pyrite and sphalerite.

Another mineralized zone is developed in a highly metamorphosed feldspar porphyritic rock, upstream from this showing. A selected grab sample assayed trace gold, 21 grams per tonne silver, nil lead and 8.6 per cent zinc (Minister of Mines Annual Report 1927, page 73).

In 1927, the Highland group of six claims was owned by Jones and Ingraham, of Alice Arm. Opencutting and trenching has exposed and traced mineralization.
