of the two main coal horizons of Jura - Cretac- 

 eous age, i.e. they occur near the top of the 

 Laberge series and are consequently several 

 hundred feet below the measures at Tantalus 

 and Tantalus butte. 



Some years ago, a slope was sunk about 

 350 feet (106 m.) on the best seam so far 

 found in these measures, and a number of rooms 

 were driven off this entry. The seam dips 

 to the east at an angle of 16 , and in the lower 

 rooms, is 3^2 to 4 feet (i-o to 1-2 m.) thick. 

 A considerable amount of coal was mined and 

 sold, chiefly in Dawson, but the workings have 

 now been closed for several years. 



The top of this old slope is situated in the 

 steep clay and sand bank of the river, and is 

 therefore unstable; consequently when work 

 was resumed under new management in 1906, 

 the entrance was shifted to safer ground, 

 some distance to the south. The new slope 

 was sunk 783 feet, (238 m.) on a seam which 

 also dips at 16 to the east, and is higher in 

 the measures than the seam in the old workings. 

 This upper seam, through in places not more 

 than 6 inches ( • 15 m.) thick, shows at the bottom 

 of the slope 22 inches (-55 m.) of good clean 

 coal, and 24 inches (-6 m.) of coal and shale. 



During 1907 and 1908, very little work was 

 done on the property. In the former year 

 a 26 ft. (7-9 m.) winze was sunk at a point 

 450 feet (136 m.) down the new slope, to a coal 

 seam 4 ft. 6 in. (1 -3 m.) thick, which is appar- 

 ently the same seam as that in the old workings. 

 Since 1908 the mine has been closed . 



The following samples were taken by the 

 writer: — Sample A is an average of the 22 inches 

 (■55 m.) of good coal in the bottom of the 

 783 ft. (238 m.) slope; and B an average of the 

 bottom of the 26 ft. (7-9 m.) winze. Assayed
