r:n h source is unknown. All other nickel used for domestic 

 consumption comes from Sudbury, Ontario. 



In the Sudbury district nickel mining was active during 1912 

 and the production, the largest on record, approximately 21,000 

 tons. The Canadian Copper Company by a series of testing 

 in tin- I'rood mine is said to have proven in this mine alone the 

 existence of 10,000,000 tons of ore. 



The Mond Nickel Company carried on development work on 

 an extension of the Frood ore body. The Alexo mine in Dun- 

 donald township shipped several thousand tons of good ore during 

 the latter part of 1912 to the Mond Nickel Company's smeltery 

 at Victoria Mines. 



The Dominion Nickel-Copper Company by a similar series of 

 drill testings has proven the existence of about 6,000,000 tons of 

 ore about one-fourth mile west of the old Murray mine. 



The imports of nickel average about $4,000,000 while the 

 exports of nickel, nickel oxide, and matte surpass $8,000,000. 



MANGANESE 



The managanese industry in the United States depends 

 largely upon the activities in the pig iron and steel industries. 

 With the increased production of pig iron during the last two 

 years there has been a greater demand for managnese ores. 

 The production, however, has been small, averaging about 

 2,500 tons per year valued approximately at $25,000. Virginia 

 and California are the principal producers. The value of the 

 imports of managnese ores for domestic consumption exceeds 

 $1,000,000. 



The annual domestic production of manganiferous ores exceeds 

 500,000 long tons. The Lake Superior region produced over 

 91 per cent, of the tonnage. The ore averages less than 6 per 

 cent, of manganese and is used a source of high-manganese 

 pig iron. The manganese ores of Colorado, which is the second 

 state in rank in this industry, are used for fluxing. These ores 

 are also argentiferous. The manganiferous ores of Batesville, 

 Arkansas, are utilized in the manufacture of high-manganese 

 pig iron in the blast furnaces at St. Louis, Missouri. 



The production of manganese- zinc residuum from New Jersey 

 zinc ores has averaged more than 100,000 long tons per annum. 

 These ores consist of franklinite, zincite, and willemite. In
