To the same district belong the Moose Mountain 

 Iron Mines, where the process of treatment, which is 

 most interesting, may be seen. The ore is taken 

 and reduced to an inch product by crushing, after 

 which the waste rock is separated by a magnetic 

 process. The ore is then placed in crushers and 

 reduced to a uniform size of less than an inch. It is 

 then conveyed to the magnetic concentrators by 

 means of an inclined belt. Next it is shot into 

 bins which discharge their contents into magnetic 

 separators, and finally conveyed into the cars of the 

 Canadian Northern Railway to be shipped. About 

 800 tons per hour can be loaded. 



Extensive iron deposits have been discovered 

 at Grand Rapids and Blairton, and marble and 

 graphite at Bancroft and Wilberforce, in the Hastings 

 district. 



Four of the iron mines produced during 1909, ore 

 to the extent of 119,207 tons, and the Helen mine at 

 the Sault yielded 112,246 tons. The returns from 

 eight blast furnaces were estimated at ;^ 1,395,483 

 worth of pig iron, and ;^i, 571,081 worth of steel. 



Cobalt is another centre of great mining impor- 

 tance. Its chief output is silver, which from 1904 

 has been a rapidly growing industry. The official 

 returns since that year are given at 93,977,833 oz. of 

 silver, valued at ;^9,665,456. 



The chief Cobalt mines and their output are as
