The Horn 5 occurrence is located the west side of a north-south–trending ridge, approximately 13 kilometres north 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 CRE95-44-3 is a baritic limestone lens, 0.5 to 1 metre thick, with barite clasts and rosettes within siltstone and black, sooty slate of the Ordovician to Lower Silurian Road River Group (Geoscience Map 1998-9).
Work History
In 1980, Noranda Exploration Company, Limited completed a soil sampling program on the area as the Smoke claims.
Cominco Ltd. staked the area in 1996 as the Horn claims and completed a program of geological mapping and minor rock sampling. A grab sample (WR96-27) assayed 19.4 per cent barium (Assessment Report 25013).
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.
