The Horseshoe Ridge occurrence is located approximately 28 kilometres northeast of Sparwood, British Columbia, adjacent to the Line Creek coal mine (MINFILE 082GNE020).

At least ten seams, with an aggregate thickness of 45 metres, occur in the Jurassic-Cretaceous Mist Mountain Formation (Kootenay Group) which is 245 to 400 metres thick and consists of interbedded sandstone, shale and siltstone. Seam 10 (stratigraphically lowest) varies from 6 metres thick in the south to 2 metres in the north. Seam 9 averages 2 metres thick. Seam 8 which is divided into upper and lower units, contains 17 metres of coal across 25 metres of section. Seam 7 is divided into an upper seam (6 metres thick) and a lower seam (3 metres thick). Seam 6 averages 4 metres in thickness. Above seam 6, four seams greater than 1 metre thick have been documented.

The coal is medium volatile bituminous metallurgical grade with average ash, volatile matter, fixed carbon and sulphur contents of 6.82 per cent, 24.61 per cent, 68.03 per cent and less than 0.5 per cent respectively (air dried basis). Free Swelling Index is on average 6.5.

The Horseshoe Ridge property forms part of the east limb of the Fording River or Alexander Creek north trending syncline. Local structure consists of an asymmetric syncline whose west limb is almost vertical while the east limb dips 25 to 70 degrees west. North-northwest trending high angle thrust faults occur on the east limb while the west limb is truncated and severely disturbed by the Fording River thrust zone. Reserve potential of the west limb is extremely limited.

Detailed exploration was completed between 1987 through 1995 when a pit at Horseshoe Ridge was developed as an extension of the Line Creek coal mine (MINFILE 082GNE020). Mining at Horseshoe Ridge began around 1997 and production has been recorded with operations at Line Creek.
