Work History
Acquired as Coal Exploration Licence #78 in Nov/77 by Pan Ocean Oil Ltd, which staked the mineral rights in Jun/78 as Illtyd cl (YA30809) and carried out geological mapping and drilled 2 holes (555 m) in 1980. The area was relicensed as #135 in Nov/80; and as CYM0012 by P. Wheelton in Dec/2001.
Capsule Geology
Three coal seams are present in a Late Cretaceous section of conglomerate, sandstone and shale in the lower part of the Bonnet Plume Formation. This deposit is a structural continuation of the Illtyd deposit. At its south edge, it is separated from the Pole (Wernecke) deposit by a ridge of Cambrian carbonate rocks. Structurally, the West Illtyd deposit is composed two east-plunging synclines, a broad northern fold and a tight southern fold, which are separated by a tight, probably faulted anticline around a Cambrian carbonate high.
One hole was drilled in each structure. Hole 80-16 tested the north syncline and intersected seams # 4 and # 5. Hole 80-19 in the south syncline intersected seams # 3, 4 and 5. Inferred in-situ reserves are 47 560 000 tonnes of high volatile bituminous C non-coking coal.
