Capsule Geology

The Eagle Mountain occurrence is located approximately 25 kilometres north-northeast of Elkford, British Columbia, and has been mined as part of the Fording River mine (MINFILE 082JSE012).

Up to 13 seams (greater than 1 metre thick) which are medium to high volatile bituminous in rank, occur in the Jurassic-Cretaceous Mist Mountain Formation (Kootenay Group) interbedded with sandstone, siltstone and shale. The main seams outcropping from north to south, include seams 15 (stratigraphically highest) 13, 12, 11, 9 and 7. The main seam in the north is the 15 seam with the stratigraphically older seams being more important towards the south.

The Eagle Mountain area straddles the north-northwest trending Alexander Creek syncline with the bulk of the area lying on the east limb, striking north-northwest and dipping 20 to 30 degrees west-southwest. The fold axis plunges north in the north of the area, and south towards the south of the area. Two main north- northwest trending, west dipping thrust faults occur on the east limb of the syncline. The 15 seam was mined by underground methods in the north of the Eagle Mountain area.

The Eagle 6 Pit (central and eastern regions of Eagle Mountain) is a mine area of 60 different seam splits including 15 splits from main seams. These seams are part of the east limb of the Alexander Creek syncline, and are from the lower two thrust blocks, below the Ewin Pass and Brownie Ridge Thrust Faults. Bedding dip angles range from 45 degrees to horizontal.

The Eagle Main 4 Pit South (southwestern portion of Eagle Mountain) is a mine area containing seams from the uppermost fault block above the Ewin Pass Thrust. Seams are mined from the western limb of the Alexander Creek Syncline. The seams dips range from 25 degrees to horizontal (Jensen, E., Knight, A., Mills, D., Musil, B. (2011-12-31): NI 43-101 Technical Report on Coal Resources and Reserves of the Fording River Operations).

In 2011, Teck Coal Ltd. estimated 92,000,000 tonnes of measured coal resources, 116,000,000 tonnes of indicated coal resources, and 70,000,000 tonnes inferred (Jensen, E., Knight, A., Mills, D., Musil, B. (2011-12-31): NI 43-101 Technical Report on Coal Resources and Reserves of the Fording River Operations).
