The Blue Flame mine is located on Lot 194, south of the Extension No. 8 mine (092GSW042). Prospecting by the Timberlands Colliery workers, resulted in the discovery of an outcrop of the Wellington seam south of the No. 8 mine. The seam ranges from 0.6 to 0.9 metres in thickness and is overlain by a bed of mudstone ranging from 25 to 76 centimetres in thickness. In places as much as 25 centimetres of excellent quality coal lies above the mudstone. The main roof comprises massive conglomerate. The coal-bearing formation dips 45 degrees to the northeast.
The coal is part of the Wellington seam of the Early Campanian Northfield Member which is part of the Upper Cretaceous Nanaimo Group, Extension Formation. Refer to the Bebans mine (092GSW026) for clarification on the Wellington seam in the Nanaimo Coalfield. About 1583 tonnes of high volatile bituminous rank coal was mined between 1952 and 1956. The mine was abandoned in January, 1958 due to persistent shaly coal.
