MI TAI OUTPUT
 OF THIS STATE
 FUR YEAR 1913

The output of gold, silver copper, lead and zinc from Arizona mines in 1918, according to the estimate of Vic tor C. Hoikes, of the United States Geological Survey, Department of the Interior, had a total value of about $205,5J0,000 an increase of $3,S0000U. There were decided increases in both the copper and the gold of Arizona during the year. The silver output Was very close to the production of 1917, but the load was only half as much, and the zinc fell to a very small production. Arizona was fortunate in being practically free from strikes, and all the smelting plants were ac- tive throughout the year.
 The production Of gold from Arizona mines increased from Sj06S 193 in 1917 tu about Spool, ,000 in 1918. This was am increase of nearly S500O00 in spite of tSe increase in thecost of supplies and the difficulties in procuring men for labor. A large part of the gold was obtained from the smelting of copper ores, the tonnage of which was increased markedly during the year, 2 but nearly half of Arizona's total gold output was due to the cyanidation of q, of MOlaVe county, known as the Oat- man region. The United Eastern re- mdIned by far the largest gold pro- ducer of the state, and the Tom Reed continued to supply notable gold out put. The Gold Road mine was not productive and the output of the Cop per Chief in Verde district was much less.
 The mine output of silver decreased slightly, from 69S3913 ounces in 1917 to about 6,7S7,O0 ounces in 1918. On account of the increase in the price of silver, the value of the output in- creased from S5,754,74 to about S6,- 569,000. It is probable that the slight decrease in quantity resulted from a decrease in shipments of lead ore, which contains considerable silver The increase in the copper output came partly from ores which contain little or no silver, such as the New Cornolia at Ajo.
 The mine output of eopper increased from 7l2,l66,S91 pounds in 1917 to nearly 717000,000 in 1918. In spite ot this increase of nearly 65000, 00C pounds in quantity, the value of the output decreased from $194,421.561 in 1917 to little over S192, 000,000 Fl 1918, as the average price of copper decreased from 273 cents to about 2f.l5 cents a pound. Aside from the steady operation of the copper plants of Arizona, two of the main features which contributed to the larger copper productions were the blowing in of the new copper smelter of the United Verde Extension Go. at Verde. neal Jerome and the continuous operation of the teaching plant of the New Cor nclia at Ajo. Another decided increase resulted from the International plant at Miami, which treats concentrates rom the Inspiration property. IT treenlee county the plants of tho shannon Arizona Copper and Detroi returned to normal outputs after tho strikes of 1917.
 The mine production of lead in Ari- zona decreased from 23,465,445 pounds in 1917, 10 less than 13,000, 090 pounds Tn 1918. The value of the output de cr sed from $2,01S,02S to about S9S5, o9H one of the main reasons for tho decrease in lead as well as in zinc Was the idleness of the Tennesset mine, in Mohave county As there We're very few shipments of zinc ort OF lead-zinc ore, the lead from residue. was considerably less. Most of the leaC came from the Copper Queen anC Shattucll Arizona properties in Co thise county
 The output of recoverable zinc de creased from 2O,s94, ,S6O pounds in ls1' 10 about 1,S00,00O pounds in 1918. Tn, value decreased from over s2,000, ,00l to about $151,00O. The Golconda mine in the Wallapai district, Mohave coun ty, formerly large producer, wa closed and the Tennessee mine, whicI produced lead-zinc milling ore. wa practically worked out and sold to tn SchuylIill Mining Co.,, which owns ad joining ground. Considerable zin shipments came from the Dequesn property, in Santa Cruz county, an,
