Last week the William Lawrence Saunders gold medal for distinguished service in mining* was awarded to James MacNaughton, president and general manager of Calumet & Hecla Consolidated Copper Co. of Michigan. Presentation was made by President Cornelius Francis Kelley of huge Anaconda Copper (no corporate kin to Calumet & Hecla) at the annual dinner of the American Institute of Mining & Metallurgical Engineers, convened in Manhattan to discuss mines, metals, men & methods...
...MacNaughton's achievement was to mine at a profit 3,000,000 tons annually of low-grade ore, averaging less than 1% copper, from the deepest mine in North America, the famed Conglomerate shaft which has passed a vertical depth of 5,000 ft. Such lean ore had never before been mined so far down. In open-pit mining, which means simply shoveling away a hill of exposed ore (as at Bingham, Utah), lodes down to 8/10 of 1% can be handled profitably. Deep-vein mining entails the cost of tunneling, drilling, blasting, hoisting, ventilating. Mining engineers consider...
...Conglomerate Mine is the only one now operated by C. & H., and in two or three years it too will be abandoned because the vein is running out. However, the company has other lodes which can be worked if copper prices improve...
When Phelps Dodge Corp. set out with cash in its pockets to woo and master rich, independent United Verde Copper Co. of Arizona (TIME, Feb. 18), most people thought it was the only suitor. Last week it was learned that there was another. American Smelting & Refining, which Simon Guggenheim took over from his brother Daniel in 1919 and built into one of the world's biggest non-ferrous metal smelters & refiners, had bought a big block of stock in United Verde earlier than Phelps Dodge. Last week in Manhattan the two suitors rushed to a meeting of United Verde...
...stockholders reassembled, four Phelps Dodge directors were elected directors of United Verde, and Louis Shattuck Gates, president of Phelps Dodge, became president of United Verde. With United Verde's annual production capacity of 68,000 tons to add to its own 168,000, Phelps Dodge will outrank Anaconda Copper in size, become second biggest U. S. copper company.
