The FFE95-23-7 occurrence is located on a southwest-flowing tributary of Matulka Creek, approximately 10 kilometres north of Gataga 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 FFE95-23-7 is represented by several horizons, 3 to 10 centimetres thick, with barite rosettes and crystals, and disseminated pyrite in siltstone and slate of the Middle Devonian to Lower Mississippian Earn Group.
One kilometre to the northwest are small chips of baritic mudstone in black, bedded radiolarian chert. A sample of the barite assayed 1.05 per cent barium (Geoscience Map 1998-9).
Work History
In 1980, Esso Minerals Canada completed a soil sampling program on the area as the Mat claims. The results of the geochemical survey indicate a scattering of low lead anomalies, and areas of zinc-copper anomalies.
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.
