The mineral tenure of the Coal Reserves is 100% held by CST Coal.
The coal resources and coal reserves reported herein are located in the western foothills of Alberta where a stratigraphic sequence of approximately 150 m of Lower Cretaceous non-marine clastic sediments contain seven coal seams ranging in thickness from 7 metres to 1.5 metres. The Company coal leases are within a larger area of economic coal measures known as the Smoky River Coalfield.The deposit is extensively deformed by the compressive tectonics of the Laramide Orogeny, with thrust faulting and folding creating thickened coal zones up to 5 times the stratigraphic thickness of the seams. Fault throw is up to 2000 m, and fold amplitudes are up to 1500 m. Dips range from flat to vertical, with the limbs of major folds being generally deformed by smaller scale parasitic folding and imbricate small scale thrust faulting.Surface resources areas are found within the most severely structured zones, where thickening of the coal seams under compressive tectonic forces is extensive. Underground resource areas are found is less structured areas where flat bottomed synclines, or gentle anticlines with limb dips of less than 25 degrees, lie between the more structured zones. These zones of gently dipping coal measures can be up to 2 km in width and in general do not show extensive structural thickening of the coal seams. Coal quality of the various coal resource areas is well understood from an extensive database of exploration core sampling, exploration adits, and by sampling of processing operations during previous mining. Coal rank ranges from semi-anthracite to the boundary between medium and low volatile bituminous coals. The majority of the coal resources are within a mean maximum reflectance range of 1.50 to 1.65%. In-seam ash varies between 11% and 35%; in-seam sulphur varies between 0.30 and 0.70%.
