The FFE95-27-7 occurrence is located in the southern headwaters of Matulka Creek, 7.5 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 FFE95-27-7 is represented by galena-bearing quartz in highly fractured slate and siltstone of the Middle Devonian to Lower Mississippian Earn Group or Cambrian Kechika Group. Baritic limestone occurs nearby and 700 metres to the northeast are 1- to 5-centimetre thick beds of baritic limestone and occurrences of barite crystals and pyrite within slate and siltstone. A sample of the galena-bearing quartz vein assayed 3.14 per cent lead, 0.14 per cent zinc and 15.7 grams per tonne silver (Geoscience Map 1998-9).

Cominco notes mineralization sporadically distributed over an area of 10 by 8 metres. Galena and sphalerite in quartz calcite veins and disseminations occur in fractured, silicified siltstone and slate, interbedded with grey baritic limestones. A rock sample (WR96-55) assayed 6.9 per cent zinc, 0.021 per cent lead and 4.5 grams per tonne silver (Assessment Report 24978; Bulletin 107, page 111).

Work History

In 1980, Esso Minerals Canada completed a soil sampling program on the area immediately northeast as the Mat claims. The results of the geochemical survey indicate a scattering of low lead anomalies, and areas of zinc-copper anomalies.

In 1997, Cominco Ltd. completed a program of geological mapping, and geochemical (rock, silt and soil) sampling on the area as the Net 1-30 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. A float sample (P421123) of limestone with quartz veining hosting pyrite, sphalerite and galena, located on a ridge approximately 5 kilometres northwest of the occurrence, yielded 0.49 per cent lead and 1.06 per cent zinc, whereas an undescribed float sample (P421133), located downslope to the southeast of the previous sample, assayed 0.41 per cent zinc and 9.9 grams per tonne silver (Assessment Report 33582).
