Capsule Geology

The JN95-10-10 occurrence is located on or near a mountain peak, north of Matulka Creek and approximately 6 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 JN95-10-10 comprises a calcareous barite bed, 1.5 metres thick, with small black chert nodules, within chert and siltstone of the Middle Devonian to Lower Mississippian Earn Group (Geoscience Map 1998-9).

Work History

In 1996, Cominco Ltd. completed a program of soil, silt and rock sampling on the area as the Phrase and Term claims. A sample (WR96-41) assayed 6.67 per cent barium and 0.336 per cent zinc (Assessment Report 24977).

In 1997, Hunter Exploration Group completed a minor program of prospecting and geochemical (rock, silt and soil) sampling on the area as the Mat claims.

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.
