The Bullhead Mountain coal occurrence is located about 7 kilometres north of the W.A.C. Bennett Dam, approximately 11 kilometres northwest of the community of Hudson's Hope.
The Peace River Coalfield extends nearly 400 kilometres along the Northern Rocky Mountain inner foothills from the Alberta border, 180 kilometres east of Prince George, to 130 kilometres north of Hudson’s Hope at Pink Mountain. Medium to low volatile bituminous coal seams of economic thickness and continuity are hosted by the Lower Cretaceous Gething (up to 1036 metres thick) and Gates (up to 280 metres thick) sedimentary formations of the Bullhead and Fort St. John groups, respectively. The Gething Formation represents the dominant coal-bearing strata north of the Sukunka-Bullmoose area (093P 001, 14) west of Tumbler Ridge.
Coal occurs in the Gething Formation interbedded with sandstone, siltstone, shale, and minor conglomerate. Several old mines occur on the property including the "SW", "NE", and King Gething (093O 030). The Gully seam and King seam are present along with other coal outcrops. Very little is known of coal extent, thickness or quality.
The structure consists of a series of northwest-trending folds, the West Crest Butler Ridge anticline, the Bullhead Mountain syncline and the Bullhead Mountain anticline. The latter two folds plunge to the north. The folds are cut, mainly at the south end of the property, by northwest trending, southwest dipping thrust faults such as the East Portage Mountain thrust fault. West of the property boundary to the north is the Butler Ridge thrust zone.
In December 2010, the Government of British Columbia committed to develop a plan to manage the seven northern ecotype caribou in the South Peace River area. One project undertaken to assist development of the Peace Northern Caribou Plan was a modelling exercise to develop alternate development scenarios. This project integrated the available scientific information and expert opinion to predict the future abundance of caribou. It predicted future caribou numbers based on projections of industrial build-out by the coal, forestry, wind and oil and gas sectors. The report from this project, entitled" South Peace Northern Caribou Management Model", was completed and available at http://www.env.gov.bc.ca/wld/speciesconservation/nc/.
In 1971, reconnaissance geological mapping was conducted in the Portage Mountain-Butler Ridge area on behalf of Nickel Hills Mines Ltd.
