Summary:

Coal-measures in the Bingay Main area are hosted by the Mist Mountain Formation of the Kootenay Group, of latest Jurassic to earliest Cretaceous age. The Mist Mountain Formation is underlain by Jurassic rocks of the Morrissey and Fernie formations. At the crest of the Greenhills Range, east of the Bingay Main property, the Mist Mountain Formation is overlain by the younger coal-measures of the Elk Formation, also of Cretaceous age. Although younger coals are known from the overlying Elk Formation in the Greenhills Range, the Elk coals appear to have been stripped away by erosion within the Bingay Main property. At least 32 coal beds, whose true thickness ranges from 0.3 to 16.2 metres are present. Of these coals, 24 typically are at least 1 metre thick, inclusive of contained bands of rock. Cumulative thickness of these coals is 62.6 metres, within an overall coal-bearing rock thickness of 460 metres; coal thus forms about 13.6% of the coal-bearing rocks at Bingay Main. Bedrock in the proposed mine area consists primarily of siltstone, mudstone and sandstone with interbedded coal seams, which are exposed in the central Bingay Hill and along the east side of the proposed open pit adjacent to the Elk River. The mudstone, siltstone and coal layers appear relatively soft, however coal-bearing erosion resistant sandstone layers form prominent bedrock ridges in the southwestern part of the proposed mining area and along Bingay Creek.

Overburden, generally consisting of coarse sand and gravel is present on the west and north sides of the proposed pit area, and thick silt and clay is located on the north side of the proposed pit area. Thin deposits of silty sand and gravel overlying bedrock are present on the proposed pit’s south and east sides.
