Miami to Use Big Shelter.


 International Smelling and Refining Company's custom shelter at Miami, Arizona-planned and erected to treat Inspiration ores-the Miami company's smelt Miami concentrates will be transferred to the local International plant. Inspiration. International Smel. ting X Refining and Greene Cananea are all controlled by the same inter- ssts, and no difficulty is contemplated in the transfer of Miami's present smelling contract with Greene Cana hea, or at least the "sub. letting'' of the contract to the new plant at Miami
 As was announced in the Mining being broken and the site prepared for the big International smeltery at Miami. McArthur Bros, the con- tractors who did much of the prehmi- nary construction for Inspiration, are preparing the ground. Actual con. struction of the shelter will begin about Jan. 1, 1911, by Redpath & Me. Gregor, the firm of constructing en- gineers which has been engaged upon all the big copper mills in Arizona. The shelter will be completed in the fall of 1911. but will probably not go on permanently producing basis be- fore January, 1915. It will handle in, spiration, Miami and local ores, and will have to import pyrltes or sul- phide ores for tluxing.
 The smelling of Miami concentrates at Miami instead of at Cananea. Mex- co. will effect d saving of IS per ton in transportation charges, or between l75,0JOS and 200, ,0OOS per annum, based on present Miami shipments (about 4S,000 tons per annum) With the in- crease in Miami's nilllng capacity, as announced in the Mining Age two weeks ago, from 5000 to 4,00O tons daily, proportionate increase in say. ing would, of course, be effected. At present the freight charges from Miami to Cananea, Mexico. is 4.50$ per ton. It is estimated that Miami new shelter at Miami at a cost of 50 cents per ton or less.
 Miami shareholders must not, how every jump at the conclusion that the saving of 4S per ton will rebound ep. tlrely to Miami As matter of fact this item of saving has already been discounted, and Miami will have been enjoying the fruits of the saving for Is months in advance of the actual com. pletsOn of the new smelter. When Miami and Greene. Cananea abrogated their old smelling contract, and enter ed upon new agreement, beginning in July, 1913, and lasting little over 10 years, it was with the understand ing that Greene-Cananea might ulti. mately transfer the contract, or at least the actual smelling of the ores, to the new International smeltery at
 
 smeltery was planned and constructed not so much for Inspiration ores alone, but on the understanding that Miami ores and other ores of the district would also be handled. It was only upon such an understanding that the profitable construction and operation of the new International shelter could be at all possible.
 When Miami signed it's new smet- ing contract with Greene Cananea it was given reduction, taking effect immediately, of one-half cent per pound Tn the smelting-transportati charges, and as Miami concentrates run 700 pounds of copper per ton, this amounts to a reduction of 3.50S per ton from previous prevailing rates Miami has thus been granted reduc- tion of 3,5OS per ton, taking effect in July, 1913, instead of having to wait Is months for a possible-though not certain-4 OOs reduction. Were Miami to have made its contract directly the International Smelling x Refining Company it might have saved IS per ton in transportation charges-pro- vided, of course, it received the same smeltlng rate as granted by Cananea- but this saving would not have be-
