limestone, and are on the axis or an overturned 

 and broken anticline, the contact of the lime- 

 stone and the Kootenay being a faulted one with 

 easterly downthrow, with the result that the 

 lower beds of the Kootenay and all of the Fernie 

 shales are cut off, and do not reach the surface. 

 The Canadian Coal' Consolidated is operating 

 two mines at Frank ; the first is opened by a drift 

 parallel to the face of Turtle mountain and 

 driven in a southerly direction. Three seams 

 have been proved but one only, the highest, is 

 being worked; this seam is from 12 to 15 feet 

 (3-6 to 4-5 m.) thick. The coal is hauled along 

 the main level and to the tipple by means of 

 gasoline locomotives. The daily output (July, 

 1912) amounts to about 300 tons. 



No. 2 mine is situated about one-half mile 

 north of No. i and is being operated by means 

 of a shaft 330 feet (100-5 rn-) in depth. The 

 main level, driven from the bottom of the shaft, 

 runs in a northerly direction towards Bluff 

 mountain. From this mine the daily output 

 is about 450 tons. 



LILLE COAL MINE. 



From Frank, the Frank and Grassy Mountain 

 railway branches off to the north and follows 

 the valley of Gold creek for about 7 miles. 

 About 5 miles up this line the town of Lille 

 is situated where the West Canadian Collieries 

 are operating their Lille mine. A coal seam 

 4 to 5 feet (i -2 to 1-5 m.) in thickness has been 

 worked here quite extensively. The mine is 

 operated on the pillar and stall system with 

 compressed air haulage on the main levels, 

 the tipple capacity being about 1,200 tons in 

 two shifts. The company has also a coking 

 plant at this point consisting of a washery for 

 treating the slack coal and a battery of 50 

 Belgian ovens of the Bernard type.
