The Chief occurrence is located in an east-facing creek valley, approximately 12 kilometres northeast of Terminus Mountain.

Regionally, the area lies immediately east of the Northern Rocky Mountain Trench, which here coincides with the Kechika River valley, in a broad belt of Paleozoic basinal-facies sedimentary strata known as the Kechika Trough, part of Ancestral North America (Map 38; Exploration and Mining Geology, Volume 1; Geological Survey of Canada Map 1713A). The area is underlain by a generally northwest-trending and southwest-dipping belt consisting dominantly of quartz arenite sedimentary rocks the Cambrian Gog Group, a strongly deformed sequence of grey to brown dolostone, shale, siltstone and chert of the Silurian to Devonian Road River Group and a varied unit composed mostly of chert-pebble conglomerate and quartz sandstone, and blue-black siliceous shale and siltstone of the Devonian and Mississippian Earn Group (Geological Survey of Canada Map 42-1962, 1712A; Geoscience Map 1998-9). All rock units have been deformed into tight, northeast-overturned folds and imbricated by thrust faults.

Sample FFE95-46-11 comprised a massive to flaggy, 2-metre-thick bed of crystalline calcareous barite within argillites of the Middle Devonian to Lower Mississippian Earn Group (Geoscience Map 1998-9). In 1996, a 2.3-metre chip sample assayed 36.9 per cent barite (Assessment Report 25012).

Nearby, a 3-metre-wide breccia zone, crosscutting the argillite, comprises a matrix of calcite, barite, limonite, quartz and minor sphalerite. A grab sample of the breccia assayed 0.58 per cent zinc and 1.43 per cent barium (Assessment Report 25012).

Approximately 200 metres to the northwest is the Brave zone, where a 30-metre long by 5-metre-wide talus/kill zone exposes blocks of massive barite.

Work History

The occurrence was discovered in 1995, Cominco Ltd. subsequently staked the area as the Chief claims in 1996 and completed a program of prospecting, geological mapping and geochemical (rock, silt and soil) sampling.

In 2011 and 2012, BCarlin Resources Ltd. completed regionally extensive programs of geochemical (rock, silt and soil) sampling on the area as the Netson Lake property.
