The JWR showing is located adjacent to Tagish Lake on its eastern shore, approximately 31 kilometres northwest of Atlin.

The area is underlain by argillite, greywacke, wacke and conglomerate turbidites of the Lower Jurassic Inklin Formation (Laberge Group).

Locally, a 2-metre-wide shear zone is exposed over 7 metres and contains a 0.04-metre-wide veinlet of massive sulphides. These consist of arsenopyrite, galena, sphalerite, chalcopyrite, and pyrite with a gangue of carbonate quartz.

In 2000, the JWR showing was discovered by D. Connolly and R. Smith of Atlin, while searching for meteorite fragments which landed on or near Tagish Lake in January 2000. The showing consists of man-made workings, of an unknown age, located 10 metres from the shore of Tagish Lake. In 2007, 10 rock samples were collected by C. Aspinall. Assays returned up to 15.28 grams per tonne gold, greater than 100 grams per tonne silver, 0.56 per cent copper, greater than 1 per cent lead, greater than 1 per cent zinc and greater than 0.2 per cent antimony (Assessment Report 29480). The showing consists of a small veinlet of massive sulphide, 5 metres of which are in a trench and 2 metres of which are in a shaft. Scarcity of outcrop in the area suggested potential for more such veins below till cover.
