 THAN 'l3
Estimated Value Of Silver, Gold, Lead, Copper And Other PreC- iouS Metals Is Seventeen Per- cent Less
BISBEE MINES PLAY
 BIG PART IN OUTPUT
Copper Rt Lower Price And Re- duced Amount Produced Is Chief Cause For Less Revenue During The Year Past

The value of the gold. silver, copper, lead, and zinc proudced at mines in Arizona in 1914 decreased over l69s as compared with 1913, owing princi. pally to the lower price Of copper on account of the European war accord ing to V. W. Heikes, fthe United States Geological Survey, who esti- mated the output for 1914 at S59,OOO,. 900. compared wltn S7O,s75.O27 for 1913 There was very little decrease, however, in the output of copper. lead and zinc, and considerable increases were made in gold and silver.
 The mine yield of gold in Arizona in- creased from S4.O23,9ll in 1913 to about $4,57O 900 in 1914. This Increase of nearly 14C5 was almost entirely in siliceous ores of gold and silver mines. The Tom Reed, Gold Road. Vulture, and Commonwe ealth mines produced more than half the total gold of the State, the remainder coming chiefly from copper ores. Increases were made at both the Tom Reed and Gold Road mines, and a notable quantity came from the silver ores cyanided at the Commonwealth property Several new gold mills were built one at Che Goldfeld mine in Pinal county ana several in Yavapai county
 1 A record production of silver was made in Arizona in 1914, notwithstaud- ! ing the reduced market price The out i put increased from 3,94s,O9l ozs. in 1913 to about 4,469,OO0 ozs in 1914. i The increase of over l3Gt resulted from the treatment of more siliceous . silver ore. Most of the silver came ! from copper ores, and most Of the re- mainder from siliceous ores and lead ore. At Pearce, in Cochise county. the Commonwealth mill was treating, by
 the cyanide process, about 300 tons of f silver ore a day.
 While Arizona still leads in copper production, the output decreased, on
 account of market conditions. from
 4O7. .923, ,4O2 lbs, in 1913 to about 3SS,
 GOO 900 lbs in 1914, a decrease of near lly 2OOOO,OOO lbs,. or about 5CS. Al though the production at most of the
 copper plants was less the Hayden
