The Stone barite occurrence is situated in the headwaters of a small creek, 4.5 kilometres northeast of the Alaska Highway, 8.5 kilometres northwest of Summit Lake (Open File 1992-16, page 39).
No geological description is available. From its location, the occurrence is hosted in the Middle Devonian Dunedin Formation, not far from the top of the underlying Devonian Stone Formation (Geological Survey of Canada Map 1343A). This unit is composed of grey, well bedded limestone, and minor calcarenite and dolostone (Geological Survey of Canada Memoir 373). Paleozoic rocks in this region are deformed by moderate folds and northeast-verging thrusts. The Dunedin Formation hosts other barite deposits in the area, the closest being the Mile 397 Barite showing, 4 kilometres to the south-southwest.
The only known reference to the showing denotes carbonate-hosted barite with accessory fluorite (Open File 1992-16, pages 39 and 76 (Item 093)).
