Work History
The presence of coal float on the bars of Wind River, about 15 km downstream, was noted by the Geological Survey of Canada in 1905. This target was acquired as Coal Exploration Licence #79 in Nov/77 by Pan Ocean Oil Ltd, which carried out geological mapping and drilled 1 hole (111 m) in 1979 and 1 hole (276 m) in 1980.
The area was relicensed as #136 in Nov/80; as #368 in Nov/83; and as CYM0011 to P. Wheelton in Dec/2001.
Capsule Geology
Three coal seams are present in a Late Cretaceous (Cenomanian to Maastrichtian) section of conglomerate, sandstone and shale that forms the middle unit of the Bonnet Plume Formation. The coarse clastic rocks were laid down in wet alluvial fans and braided rivers while the associated silt, mud and coal were deposited in lacustrine, paludal and overbank flood plain environments and were preserved by rapid progradation of conglomeratic fluvial sequences.
The coal deposit occurs within a WNW-trending syncline about 5.5 km long and 3.5 km wide. The steepest dips of up to 30 or 40 degrees occur on the northeast flank. Three seams outcrop along the Wind River but only the upper two were intersected by drilling. They have been correlated with the upper 3 seams at the Illtyd deposit (Minfile Occurrence #106E 035). The upper (#1) seam averages 5.5 m thick. Shale and conglomerate form the hanging wall and shale only forms the footwall. The #2 seam lies 58 m beneath the #1 seam. It is 4.9 m thick and is interbedded with shale. Inferred in-situ reserves are 18 400 000 tonnes of high volatile, bituminous C non-coking coal.
