Mohave County miner., 1914-01-24
Arizona Metal Mine Production.

duction of gold, silver, copper, lead, and zinc in Arlzona, according to pre- liminary figures of V. c. Heikes, of the United States Geological Survey. The total value of the mine output was about 1000, ,O00$, an increase of nearly 6 per cent over the value of 1912, which was 67,O50, 7S4S. The copper output was valued at nearly 64,000, ,000S; the gold at about 3,94S, ,OOOS; the silver at more than 2,263, ,OOOs; the lead at 6l2,- 000S; and the zinc at 5lO,OOJS.
 The mine yield of gold in Arizona in 1913 was more than l9l, 1000 ounces, an increase of per cent over the output of 19l2, which was l8l,996.9l fine ounces. Of this total, over 42 per cent was taken from slliceous ores and most of the remainder came from copper ores. which are undou otedly the source of the increased gold output in 1913. The three largest producing gold mines were the Tom Reed, Gold Roads. and Vulture. The Tom Reed output
 
 Gold Roads had slight increase, and the Vulture a substantial increase. h Yuma county operations were, re- sumed at the La Fortuna mine.
 The mine production of silver h. creased about per cent amounting to more than 3,773,000 ounces, against B.. 49O,3S ounces in 1912 Most of the silver was derived from copper ore, but in 1913 the increase is due largely to shipments of lead ore and concsp. trates from Cochise and Mohave coun- ties. Much silver also comes from silic- eous ore. About 800 tons of ore per month was shipped from the Tomb stone property and large tonnage of old tailings was taken from the Con- monwealth dump. A $50 ton cyanide mill at this property was completed during the year.
 With mine production of about 4l4.593,O00 pounds of copper in 1913, Arizona led all other copper.produc- ing States. The output in 1913 shows an increase of more than 49,OO0.0OO pounds, or about l2 per cent over that of 1912, which was 362 ,O3S, ,649 pounds. As the price of copper was slightly tower in 1913. the value of the metal increased only about 3,500,000$ There were II active copper smelling plants ln the State, and ore and concentrate were also sent to 6 copper and lead plants h other States. Of the former, the greatest increases iu output were made at the Hayden, Calumet x Ari- zona, Copper Queen, Old Dominion. Consolidated Arizona, and Swansea plants. At the United Verde and De- troit plants there was Ii tie change froc. the figures of 1912. Those mak- ing less copper were the Shannon, Arizona Copper, and Pioneer plants. New plants were completed by the Arizona Copper and Calumet and Ari- zona cont panies, and another was in course of construction for United Verde ores. The disseminated copper mines in Gila, Pinal and Greenlse counties yielded approximately 145,- 5OO,O pounds of copper. Included in this estimate of copper produced are the outputs of the Miami, Ray, Ari- zona Cooper, and Detroit mines. The Miami product did not greatly exceed that of 1912. The 3,000.ton concentra- tion plant was active and the product went mostly to Cananea, Mexlco. The International Smelling & Refin- ing Co. will build copper plant at Miami to treat this ore and that from the Inspiration mine. Test plants using the Notation process were oper- ated at the Miami and Inspiration, as the saving by concentration alone is not sufficient. The Ray Consolidated | Copper Co. greatly increased it's out put, from nearly 36,000,O0 pounds of copper in 1912 to about 52,00O, ,OO0 pounds n 1913, treating 5000 tons of ore per day. Production from Yuma and Pima counties was not what it could have been, since the Swansea and Pioneer plants were operated only few months. At Globe greatly in- creased shipments were made from the Superior x Boston, Iron Cap, and Black Warrior mines, and in Pinal county from the Magma mine.
