Coal Resources have not been re-estimated since 2015.

On December 21, 2022, after careful deliberation, the Government of Canada determined the significant adverse environmental effects of the proposed Sukunka Coal Mine Project, an open-pit metallurgical coal mine located near Tumbler Ridge, British Columbia, could not be mitigated. The project therefore cannot proceed.

Deposit Type

  • Sedimentary


Summary:

The Sukunka Project lies within the elongate, disturbed Foothills sedimentary belt of northeastern British Columbia. The coal licenses are underlain by the transgressive/regressive Lower Cretaceous Bullhead and Fort St. John Groups that consist of fluviodeltaic and marine terrigenous clastic sediments that have a maximum composite thickness, excluding those of the Minnes Group, of 1,100 m. The oldest lithologies exposed within the property belong to the Minnes Group. That unit is overlain by the Cadomin, Gething, Moosebar, Gates, Hulcross and Boulder Creek Formations.

In the southern half of the Peace River Coal District the coal beds within the Gates Formation constitute the primary exploration target. Recent mine developments and coal exploration activities have focused on these coals. The Gates Formation is an 80 to 280 m thick interstratified sequence of mainly non-marine sandstone, conglomerate, coal, shale and mudstone. It is separated from the underlying Gething Formation by interstratified fine grained marine deposits assigned to the Moosebar Formation. Within the formation, eleven coal beds that have a maximum thickness of about 10 m and an aggregate thickness of up to 46 m have been reported. Four or five laterally extensive seams, ranging in thickness from 5 to 10 m, are common between Kakwa and Sukunka rivers. The Peace River Arch apparently controlled the northern extent of alluvial-deltaic environments where the major coal beds originated.


Mining Methods

  • Truck & Shovel / Loader
  • Longwall


Summary:

The Sukunka deposit outcrops around many parts of the tenure which makes it suitable for contour mining. Excavation will be carried out using conventional open pit mining equipment. Mining will be conducted in two discrete areas, the Nose and Window pit area in the northern part of the property and the Saddle Creek area in the south east. The amount of waste rock to be removed over the life of the open pit operation will be approximately 725 MBCM with the maximum annual extraction rate being around 40 MBCM. Extraction rates for the open pit are based on a 12.4:1 ROM strip ratio. This strip ratio is based on current knowledge, and will be updated with the results of on-going exploration. ROM coal production will initially be in the range of 2 to 3 Mt/y, increasing to approximately 7.5 Mt/y when underground mining commences.

The proposed underground mining will be accessed from around the Chamberlain Creek area from the highwall of the open cut. A series of longwall coal panels will be developed extending northeast to the Nose area and southwest towards the Saddle Creek open pit.

The overall plan for the Sukunka Project is to:
- Excavate raw coal and waste rock from three open pits within the property boundary using conventional open pit mining methods and equipment
- Excavate raw coal and waste rock from an underground longwall mining operation within the property boundary using conventional underground mining methods and equipment
