The East Mount Gething coal occurrence is located 21 kilometres west of Hudson’s Hope, in the Liard Mining Division. The property is largely confined by Williston Lake on the north and east, Mount Gething on the west and Gaylard Creek on the south.
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 (MINFILE 093P 001, 093P 014) west of Tumbler Ridge.
More than 80 coal seams, varying from 1 centimetre to 3.8 metres thick, including splits, occur in the greater than 610-metre thick Lower Cretaceous Gething Formation (Bullhead Group), interbedded with sandstone, shale and siltstone. The strata were deposited in an aggrading flood plain environment, with the coals forming in abandoned river channels, river floodplains and more deltaic settings.
The structure consists of a broad north-trending, south-plunging syncline that lies towards the eastern boundary of the property. The central part of the property is underlain by relatively flat-lying Gething Formation rock and is flanked by asymmetric anticlines to the west and east, which are probably related to north-trending, west-dipping thrust faults at depth.
Three seams are laterally continuous and considered to be of economic interest. The Milligan seam averages 0.91 metre thick and varies from 0.45 to 31.3 metres thick; the Louise seam averages 1.08 metres thick and varies from 0.55 to 1.65 metres thick and the Riverside seam averages 1.78 metres thick and varies from 0.6 to 3.15 metres thick.
The Milligan seam is medium volatile bituminous thermal grade coal with a sulphur content varying from 0.76 to 1.30 per cent (averaging 0.94 per cent) and an ash content varying from 3.65 to 17.94 per cent (averaging 10.25 per cent). Thickness decreases away from drillhole 77-10 and sulphur increases away from drillholes 72-2, 75-5 and 75-6. Ash content trend is similar to the latter and may be related to a more marine influenced depositional environment (Coal Assessment Report 520).
The Louise seam is medium to high volatile bituminous coal, thinning from drillhole 72-1 to the southeast. Sulphur content is low, varying from 0.54 to 0.84 per cent (averaging 0.68 per cent) and ash content varies from 5.31 to 29.43 per cent (averaging 18.46 per cent).
The Riverside seam is medium to low volatile bituminous with sulphur values ranging from 0.36 to 0.80 per cent averaging 0.56 per cent and ash content ranging from 6.70 to 29.28 per cent (averaging 16.02 per cent). Thickness decreases away from drillhole 77-7. This seam contains numerous splits.
In 1970, Trend Exploration Ltd. conducted geological mapping on the property. In 1971, Utah Mines Ltd. became owner and operator of the East Mount Gething property under an agreement with Trend Exploration Ltd. Since this acquisition, Utah Mines conducted exploration in 1972 and 1973, 1975, 1977 and 1981. Geological mapping and diamond and rotary drilling were undertaken; 3508 metres of diamond drilling and 811 metres of rotary drilling were completed during the five programs. In 1982, Utah Mines completed extensive detailed geological mapping and rotary drilling (four holes totalling 766.8 metres).
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 in 2012 and is available at https://www.env.gov.bc.ca/wld/speciesconservation/nc/documents/Final_Wilson%20%202012%20%20PNCP%20management%20model.pdf.
