METAL MINING IN
 ARIZONA SUMMARIZED

The value of gold, silver, copper lead and zinc mined in Arizona in 1918 was $202, 2,134,S80, the greater part of which was for copper, accord- ing to V. c. Heikes of the United States Geological Survey, department of the interior. Arizona continued to be the largest producer of copper in the United States and will probably maintain it's position in 1919, but with a greatly reduced output during the first six months, when curtailment of production followed the reduction in the prices of metal.
 The output of gold in Arizona in 1918 was 262,919,43 ounces, valued at $, ,435, ,027, which represents consid- erable increase over that of the prev ious year. The United Eastern and other gold mines in Mohave County which contribute the largest part of the states output of gold, continued to produce heavily during the first half of 1919, the grade of ores permitting mining under the prevailing high costs. The Gold derived from copper ores, however, will undoubtedly be much less in 1919 than in 1918, for two of the large mines and smelters near Jerome were closed for three months. The copper ores of the Ray Consolidated, Miami and Inspiration contain little or no gold, but the ores of the Copper Queen, Calumet & Ari- zona, United Verde, and United Verde Extension contain much gold.
 Most of the silver produced in Ari- zona is derived from copper ores and lead ores. The total output of silver in 1918 was 6,686,152 ounces valued at $1 an ounce. Mines in Yavapai and Cochise county produced the greater part of it. In 1919 there will probably be an decrease in output correspond ing to the reduction in the output of copper. With the increase in the price of silver, some of the old mines in Yavapai county will become produc- CTS, and the new mill that treats the silver ores of the Blackberry property, in Mohave county, will probably add to the output of silver in 1919.
 The production of copper in Arizona was 764,S85,874 pounds in 1918, against 712,166,S91 pounds in 1917. The market for copper in the first part of 1919 was decidedly poor, and the price decreased from an average of 24.7O cents per pound in 1918 to about 15 cents in March 1919. Much copper in ingots was piled in nearly all the shelter yards awaiting ship ment, and only the greatly reduced current production, was sent to the eastern refiners. Several of the smelt- ing plants were closed, the Shannon in January and the Sasco, United Yer de and United Verde Extension in February, though the last two resum- ed operations in May and June. The mines were producing at the rate of about 60 per cent of their output in 1918. The monthly production of the Inspiration and Miami companies was close to that of the previous year, but the Ray Consolidated was making half of it's former output. There was general scarcity of miners and me- chanics, and even the return of the troops railed to meet the demand; but the curtailment has permitted mine development and repair and construc- tion of furnaces after period of for ced production. One of the interest ing features of the work of the first six months of the year was the con tinuation of stripping by steam shovel on Sacramento Hill at Bisbee. The United Verde began work with steam shovels to uncover large body of low grade ore and kept large force of men making extensive improvements and additions to the capacity of the new smelting plant at Clarkdale. At Ajo, the New Cornelia Copper com pany plans to construct 5O0-ton ex- perimental Notation plant for it's sul-
