The JRG showing is 220 metres northeast of Allison Creek and 2.5 kilometres northwest of the creek's confluence with Summers Creek.

A zone of skarn alteration occurs in a stock of monzonite and granodiorite of the Middle to Late Cretaceous Allison Creek stocks. The zone is developed over an area 36 metres long and up to 27 metres wide. The skarn contains epidote, quartz, magnetite, pyrite, malachite and minor chalcopyrite. A grab sample assayed 0.01 gram per tonne gold, 7.7 grams per tonne silver and 0.322 per cent copper (Assessment Report 11859, assay certificate, sample JRG-016).

An area of mineralized calcite veinlets occurs in augite plagioclase andesite of the Upper Triassic Nicola Group, 400 metres to the north. A sample of a calcite veinlet with malachite and minor pyrite assayed 0.01 gram per tonne gold, 11.4 grams per tonne silver and 1.779 per cent copper (Assessment Report 11859, assay certificate, sample JRG-018).

A third area of mineralization occurs 300 metres southeast of the skarn zone. Here, a roadcut in lithic and crystal tuff contains pyrite and chalcopyrite.

The showing was mapped and sampled by Laurie Resources Inc. in 1983.
