At the Line Creek operations, sixteen coal zones (E, D, C, B, A, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10B and 10A, from top to bottom) with a net aggregate thickness of 67.4 metres in 91.7 metres of gross aggregate coal section, occur in the Jurassic-Cretaceous Mist Mountain Formation (440 to 500 metres thick) (Kootenay Group) interbedded with sandstone, shale and siltstone.

The main seams are the 10B seam (average thickness 4.5 metres - thins north); 9 seam (two seams, average thickness 5.4 metres in a 6.4 metre zone - thins north and west); 8 seam (thickest seam - averages 11.6 metres in a 12.8 metre thick coal zone); 7 seam (averages 5.2 to 6.3 metres); 6 seam (two seams average 5.0 metres and 12.0 metres respectively - thickens southwest); 4 seam, which in the south is two seams, 5.0 and 12.5 metres respectively, and in the north is a single thick seam but with a shale split in the northeast, 11.6 and 12.0 metres respectively; 3 lower seam (single or multiple thin seams - 3.3 to 3.8 metres, disappears to the northwest); 3-Upper seam (4.0 to 6.0 metres average thickness, lower 50 to 75 per cent is a single coal seam with thin variable shale splits, upper portion consists of multiple thin coal seams with shale partings); and A seam (2 seams in the south, single thick seam in the north, average thickness is 3.0 to 4.0 metres). The remaining seams are commonly multiple, thinner (less than 3.0 metres) and tend to contain shale partings.

Ash contents range from 5 to 16 per cent (generally 7 to 8 per cent), volatile matter from 19.5 to 30.0 per cent and sulphur from 0.3 to 0.9 per cent (air dried basis). The coal is medium volatile bituminous in rank.

The main structural feature in the area is the north-northwest trending Fording or Alexander Creek syncline which plunges 10 degrees north with a nearly vertical axial plane. The limbs of the fold are symmetrical, with dips on the west limb ranging from 5 to 10 degrees near the axis, to vertical and overturned in some outcrops. Dips on the east limb are 5 degrees near the axis, and up to 60 degrees west near the east limb. The east limb is complicated by faults and drag folding associated with the Fording thrust zone, while imbricate, shallow east dipping thrust faults occur on the west limb.

Proven reserves at Line Creek Extension are 19,800,000 tonnes of run-of-mine thermal coal. Surface mineable coal reserves in the current Line Creek open pit mine are 41,336,000 tonnes of which the in-situ coal is broken down as follows; metallurgical coal - 30,756,000 tonnes, and thermal coal - 10,580,000 tonnes (Line Creek Expansion, Phase I Information Brief, September 1981, Phase II Application, May 1984).

Line Creek Resources Ltd. is building a conveyor to move coal 10 kilometres from the raw coal stockpile to the plant. The conveyor will cost about 30 million dollars and will have a capacity of 7 million tonnes per year. Currently, clean coal production is 2.2 million tonnes metallurgical coal and 0.6 million tonnes thermal coal. A new pit is being developed on Horseshoe Ridge (082GNE021) and the haul road to this area is under construction. Approximately 15,000 metres of exploration and development drilling were completed in 1995 (Information Circular 1996-1, page 9).

The Line Creek mine was acquired by Luscar Ltd. when it took over Manalta Coal Ltd. in mid-1998. Production for the year was about 3.2 million tonnes. In-pit development drilling totalled about 19,000 metres.

Reserves at January 1, 2000 are 38.1 million tonnes (Information Circular 2001-1, page 6).

As of 2015, Teck produces hard coking coal, pulverized coal injection, and thermal coal from the Burnt Ridge South, North Line Creek, and Horseshoe pits at the Line Creek Operations. Expansion plans are underway at Line Creek Phase II, which received conditional Environmental Assessment approval in 2013. This expansion will extend operation northward, to encompass the Mount Michael (MINFILE 082GNE022) and Burnt Ridge North (MINFILE082JSE001) areas. The Burnt Ridge Extension project entered pre-application of Environmental Assessment in June 2014. This extension will connect the current Phase I operations area to the Phase II area. Drilling in 2015 focused on the Burnt Ridge and North Line Creek extension areas to upgrade the geological and geotechnical models (Information Circular 2015-1, 2016-1).

At the 2015 production rate of around 3 million tonnes per year, the Line Creek Operation has an estimated 22 year mine life.
