Work History
Discovered during geological mapping and prospecting carried out by Resoursex Ltd in 1975, on its Coal Exploration Licence #35, which was issued in Jan/75. This area was previously held under Licence #13, issued to N.H. Ursel & Assoc. Ltd in Sep/70.
In Oct/92, Cash Resources Ltd aquired coal exploration rights to the area surrounding the occurrence under various Coal Exploration Licences (#479,# 480,# 486,# 487) that also encompass the Division Mountain coal deposit (Minfile Occurrence #115H 013), 6 km to the southeast. In 1997, Cash carried out hand trenching in an area containing numerous patches of coal float, 3 km southwest of the occurrence. In Nov/98 Usibelli Coal Mine Inc optioned the exploration area from Cash and in Mar/99 carried out reverse circulation drilling of an area 2 km north of the occurrence. Usibelli subsequently dropped its option, due to low world prices for thermal coal.
In May/2001, Cash Resources Ltd was renamed Cash Minerals Ltd.
Capsule Geology
Coal float was found in gopher holes in an area underlain by Upper Jurassic to Lower Cretaceous Tantalus Formation clastic rocks and Upper Jurrasic Tanglefoot Formation of the Laberge Group. The upper member of the Tanglefoot Formation consists of sandstone, siltstone, carbonaceous shales and coal seams, which occur approximately 210 to 240 m stratigraphically below the base of the overlying Tantalus Formation (Long, 1986).
Trenching on the south side of Cub Mountain, exposed Tanglefoot formation lithologies but apparently did not reach bedrock. Drilling north of Cub Mountain targeted a southeast plunging anticline, four holes were drilled across the crest of the anticline and three holes were drilled into the northeast limb. Two of the three holes drilled on the northeast limb intersected narrow coal seams interbedded with sandstones and carbonaceous shales.
