The Fisher Creek coal occurrence is located on the north side of Pine River, 43 kilometres west of Chetwynd. The Fisher Creek prospect is on the Willow Creek mine lease (093O 008).
In the Fisher Creek area, two main coal seams occur in the Lower Cretaceous Gething Formation (Bullhead Group), interbedded with sandstone, siltstone, claystone, carbonaceous claystone and minor coal seams. Seams are of medium-volatile bituminous coal and vary from a few centimetres to 1.96 metres and are generally 0.5 to 1 metre thick. The main seam zones, lower and upper, are 0.6 to 6.7 metres and 0.3 to 3 metres thick, respectively. From three trench samples, ash, moisture, volatile matter, fixed carbon and sulphur were found to vary as follows: 11.2 to 24.7 per cent; 2.8 to 8.3 per cent; 21.8 to 25.7 per cent; 48.0 to 60.3 per cent; and 0.68 to 0.78 per cent, respectively.
The structure is controlled by the northwest trending Fisher Creek anticline to the north and west, and by the Willow Creek anticline to the south and east. These structures have not been followed as distinct elements on the property, which contains a number of northwest trending lesser folds cut by minor high-angle reverse faults, and a northwest trending, southwest dipping thrust fault.
In 1979, Gulf Canada Resources Inc. conducted a limited geologic investigation on their Fisher Creek licences which also included three hand trenches across the coal seams.
Coal resources at Fisher Creek total 21.3 million tonnes at a strip ratio (BCM tonne coal) of 7.6:1 (BCM is bank cubic metre of waste rock). The coal resource calculation was prepared by Gulf Canada from work in the 1980s and does not conform to National Instrument (NI) 43-101 (Press Release - Pine Valley Mining Corp., April 27, 2004).
