The Canadian Nickel Corporation owns some large 

 deposits, such as the Whistle mine at the northeast corner of 

 the nickel basin, and has recently bought the long unworked 

 Murray mine, which has been shown by diamond drilling to 

 contain 10,000,000 tons of ore. 



None of the nickel-copper matte is refined in Canada, 

 that produced by the Canadian Copper Company going to 

 New Jersey for final treatment, and that of the Mond 

 Company being shipped to Swansea in Wales. 



In 191 1, 612,511 tons of ore were raised, more than half 

 of which came from the Creighton mine; and 17,049 tons 

 of nickel and 8,966 tons of copper were contained in the 

 matte produced. About 5,500,000 tons of ore have thus far 

 been mined and diamond drilling shows that ten times as 

 much remains in the different deposits. In 1912, the pro- 

 duction was 22,421 tons of nickel and 11,116 tons of copper. 



LITERATURE ON THE SUDBURY REGION. 



A very extensive literature has grown up in regard to 

 the Sudbury Nickel region, mostly devoted to the character 

 of the ore deposits and their relationships to the norite and 

 the country rocks. The first suggestion of the true relation- 

 ships was by Dr. T. L,. Walker in an Inaugural Thesis 

 published in the Quarterly Journal of the Geological Society 

 in 1897. The Geological Survey of Canada has naturally 

 paid much attention to it, the most important publication 

 being that of Dr. Barlow in Part H, Vol. XIV of the 

 Annual Reports. Dr. Barlow takes up the petrographical 

 features of the region in great detail. His work was pub- 

 lished in 1904 ; and in the following year the Bureau of 

 Mines of the Province of Ontario published the Sudbury 

 Nickel Field as part III of their XIV Report. In this 

 report, which was prepared bv the present writer, the nickel 

 eruptive was shown to be basin shaped and to form a con- 

 tinuous belt of norite-microoegmatite with which all the ore 

 deposits are connected. In 1913 a later report by the 

 present writer is to be published by the Mines Branch at 

 Ottawa, and the most recent map of the region was pre- 

 pared for the reoort just mentioned. The reader is 

 referred to these three reports for detailed accounts of the 

 region and for complete references to the literature.
