ARIZONA'S METAL
 PRODUCTION IN 1912

WASHINGTON, Jan. S-Arizona experienced in 1912 an exceptionally good year in mining, especially in the mining of copper ore, and the preliminary total value of all metals is estimated at more than $o5,OOO,- 900, an increase of more than $zO,- 100000, or 4o per cent, above the production for 1911. Of this total value, the copper output represented over SsS,0O0,0OO, gold $3,s0o,0oo, and silver, $2,OOoOo.
 The production of gold increased only about per cent, giving an output of over 10000 ounces. The two main sources were copper ore and ores amalgamat-i or cyanided. Precious mental bullion came prin- cipally form Mohave County, where great increases were made in out put by the operators of the Tom Reed and Gold Road mines, particu- larly the latter.
 Silver came mainly from copper ores and production increased to about 3,300,00o ounces in 1912, or about 2 per cent. Lead ores from Cochise and Mohave counties also contained a considerable percentage of silver. The ore of the new cop per producers, Miami and Ray, con tains so little gold and silver that it is not a relatively important source for precious metals.
 Arizona led all other states in the production of copper. The output has grown from 1oo,000.00O pounds in 1904 to about 359,OOO.00o pounds in 1912, an increase of Y per cent over the 1911 record. The value of the product was increased by over $13,000000 on account of the price of copper being higher by about 375 cents a pound in 1912. The greatest increases were made at the Ray, Miami. and Copper Queen mines, while substantial increases were made by the Arizona Copper, Detroit, Shannon, and Old Domin ion companies. In production there was little change at the Calumet and Arizona, where construction was progressing on the new smelling plant equipped with roasters to re- duce sulphide ores now found on the property. A new plant was also in course of construction at the Ari- zona Copper Company's property at Clifton, and the American Smoking & Refining Company's plant at Hayden was completed and working in June on Ray concentrates. The output was much less from the Con solidated Arizona smelter at Hum boldt, and the plant at Swansea was active only part of the year The Pioneer Smelling Company in Pima County, operated a small mating plant for a time, and the United Verde Copper Company made ar engagements for the building of large new plant near Jerome. In Santa Cruz County the R. R. R. mine developed into an important producer of copper ore.
 The lead output for 1912 was about 100000 pounds, a decrease of B per cent from that of 1911. It was, however, much larger than the production of any of the last eight years except 1911, which was un- usually high. No lead smelters were operated in the State. Lead ore from the Copper Queen and Shat tuck Arizona mines and lead concen- trates and ore from Mohave County were shipped to Fl Paso, Texas, and Needles, California
 Shelter production increased about So per cent over that of 1911 and was about S,50O0OO pounds in 1912. From the Golconda mine at Union Basin zinc and concentrate were shipped continuously, in Seotember at the rate of l,200 tons a day. Ores from Mohave County were concen- trated at Needles and shipped east.
