Show arizona mine output in 1918 the output of gold silver c opper copper lead and zinc from arizona mines in 1918 according to the estimate of 0 victor C heikes of the united states geological survey department part ment of the interior had a total value of about an increase of 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 lead 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 ilie smelting smelling sm elting plants were active throughout the year 1 gold the production of gold from arizona mines increased from in 1917 to about in 1918 this was an in increase of nearly in spite of the increase in the cost of supplies and the difficulties in producing men for labor A large part of the gold was obtained from the smelt ing of copper ores the tonnage of which was increased markedly during the year but nearly half of Ari zonas total gold output was due to the of gold ores in the san francisco district of mohave county known as the oatman region the united eastern remained by far the largest gold producer of the state and the tom reed continued to supply notable gold output the gold road mine was not productive and the output of the copper chief in verde district was much less silver the mine output of silver decreased slightly from ounces in 1917 to about ounces in 1918 on cn account of the increase in the price of silver the value of the output increased from to about it is probable that in quantity resulted the slight decrease in shipments of lead ore from a decrease which contains considerable silver the increase in the copper output came partly from ores which contain little or no silver such as the new cornelia at ajo copper the mine output of copper increased from pounds in 1917 to nearly in 1918 in spite of this increase of nearly pounds in quantity the value of the output decreased from in 1917 to a little over in 1918 as the average price of copper decreased from cents to about 2475 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 production were the blowing in of the new copper smelter of the united verde extension company at verde near jerome and the continuous operation of the leaching plant of the new cornelia at ajo another decided increase resulted from the international plant at miami which treats concentrates from the inspiration property in greenlee county the plants of the shannon arizona copper and detroit returned to normal outputs after the strikes of 1917 lead the mine production of lead in arizona decreased from pounds in 1917 to less than pounds in 1918 the value of the output decreased from 2018 to about one of the main reasons for the decrease in lead as well as in zinc was the idleness of the tennessee mine in mohave county As there were very few shipments of zinc ore or lead zinc ore the lead from residues was considerably sider ably less most of the lead came from the copper queen and shattuck arizona properties les in Coc cochise lilse county zinc the output of recoverable zinc decreased from pounds in 1917 to about I 1 pounds in 1918 the value decreased from over to about the golconda mine in the Wall Wal apai lapal district M mohave chave county formerly a large producer was closed and the tennessee Tennesse mine emine which produced lead zinc milling ore was practically worked out and sold to the schuylkill mining company which owns adjoining ground considerable zinc shipments came from the duquesne property in santa cruz county and from the hillside property in yavapai county dividends from arizona mining companies during the first eleven months of 1918 amounted to exclusive of those of the phelps dodge corporation which also operates mines in mexico and new mexico the total including those of phelps dodge corporation was nearly 45 the companies paying dividends were the miami arizona commercial inspiration iron cap shattuck united eastern united verde united verde extension arizona copper calumet arizona consolidated soli dated arizona smelting smelling Sm elting magma old dominion ray consolidated new cornelia and phelps dodge |
