GOLD AND SILVER IN 1911

The geld production in Arizona in 1911 increased slightly and the silver output considerably over the yield of 1910, according to V. c. Heikes, of the United States Geological Survey. The greater production of gold was attribu- table to the mining of siliceous lead ores, and copper-lead ores, as the total gold output from copper ores remained about the same as in 1910. The princi- pal producers of siliceous gold ores were the Tom Reed, Gold Road, North Star, Tiger, Congress, and Vulture mines, in Mohave, Yuma. Yavapai, and Maricopa counties. There is promise of an incre ased output from the dry placers near Quartzsite, in Yuma Coun- ty, and from the vicinity otGreaterville, in Cochise County. Placer mining was revived on Frisco River, in the Clifton Morenci district of Greenlee County. The dredges of Yavapai County, on Lynx Creek and near Kirkland, were not successfully operated Two dredging plants of the suction type were erected on Colorado River, one in Arizona and the other near Pahreah, Utah. Both plants are said to be operating and pro- ducing.
 The increased output of silver de- pends mainly on the increased produc- tion of copper and lead ores. All the 4ll of Picha Clifton Globe, and Jerome maintained an out put weich combined made narly the same yield of ore as in 1910. The mines of the nsolidated-Arizona and the Ray, largely made up for the idleness of the Inn erial and the curtailed out put of several other properties. How ever, there was large increase in lead output and somewhat larger zinc pro- duction, due to the greateryi yie16 of lead ore in the Warren district of COchise County and the zinc and lead ores of Mohave County. The largest silver pro- ducers of recent years have been the Commonwealth and Tombstone mines. The output of both diminished in 1911. The Commonwealth is in the hands of new owners and the Tombstone is work ed by lessees,
 Near Paradise 100-ton concentra- tion mill was started in November. The 20-stamp amalgamation and cyanida- ton mill built in 1910 at Vulture mine, in Maricopa County, has been in suc- cessful operation. New mill equipment was ordered for the Big Blue mine and the Monarch mine, the latter having been idle three years. The Tom Reed and Gold Road mines, in Mohave Coun- ty, produce gold-bearing ore, which is treated in cyanide plants. The former averaged nearly $65,0O0 in gold per month from the operation of its 2O- stamp mill in 1911, and the latter, with a better grade of ore than formerly, averaged nearly the same amount from the treatment of about 300 tons daily. In the Union Pass district the Frisco mill, recently built, provides for fine grinding and cyanidotion.
 Two other gold mills the told Grown and Ruth, were opened. In Todd Basin the Orc Planta mill is under construc- tion. The new owners of the Sothern Belle mine, in Pinal County, have ord cred l00-ton mill. The Huebabi mine, on Santa Cruz River, in Santa Cruz County, recently equipped with tube mill and cyanide plant. Large bodies of low grade ore are reported to exist in this mine. The Congress mine and mill, in Yavapai County, were closed after being operated the first three months of 1911. At the Monico and Rim con gold mines preparations were made to Operate. The Tiger mine a mill, near Crown King, were operated steady, producing gold bullion anc lead concentrates. Grading was com menced for the cyanide mill on ths Venezia mine, in Crook Canyon. II Yuma County the Stafford Lane mill near Vicksburg, was in regular opera tion. and also the North Star, at Kofa
 According to preliminary f1gure prepared by the Districtor of the Mint which do not include statistics of ex ports, the production of gold in Ariz ona in 1911 was valued at $2, 2,954, 7eo ant that of silver was 1,594, 428 fine ounces valued at $s76;93s. Final figures fo 1910 gave for Arizona s, ,413, 200 wortl of gold and 2,655.70O fine ounces c
