The Star occurrence is located about 72 kilometres southeast of the community of Dease Lake.
The area of the showing is underlain by Upper Triassic-Lower Jurassic dacitic and andesitic volcanic rocks which are intruded in the west by a small tongue of fine grained, pink syenite, probably related to the Early Jurassic McBride River pluton.
Chalcocite and malachite occur along probable shear zones and in nearby andesite dikes. The shear zones vary in strike from north to 030 degrees and dip steeply to the west. In 1969, samples assayed up to 4.5 per cent copper (Assessment Report 2154). Showing No. 1, which is the largest, is about 60 metres long by 7.6 metres wide.
In 1969, the Star claim was worked by Great Plains Development Company of Canada where they conducted a geological survey and an unspecified amount of trenching. No other work is documented.
