Gold and Silver in 1911.

flHe SOlQ prOQuCllOn III Ar1ZOua III 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 at tributable to the mining of siliceous total gold output from copper ores re- mained about the same as in 1910. The principal 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 increased out put from the dry placers near Quartz site, in Yuma County, and from the vicinity of Greaterville, in Cochise County Placer mining was revived on Frisco River, in the Clifton Morenci district of Greenlee County. The dredges in Yavapai County, on Lynx Creek and near Kirkland, were not successfully operated. Two dredging plants of the suction type were erect ed on Colorado River, one in Arizona and the other near Pahreah, Utah. Both plants are said to be operating and producing.
 The increased output of silver de- pends mainly on the increased pro- , duction of copper and lead ores. All the old copper producers at Bisbee Clifton, Globe, and Jerome maintained an output which combined made near ly the same yield of ore as in 1910. The mines of the Consolidated-Ari- zona and the two new producers, the Miami and Ray, largely made up for the idleness of the Imperial and the curtailed output of several other pro- perties. However, there was large increase in lead output and some what larger zinc production, due to i the greater yield of lead ore in the Warren district of CochiSe County and the zinc and lead ores of Mohave County. The largest silver producers of recent years have been the Con- monwealth and Tombstone mines. The output of both diminished in 1911. The Comm monwea1th is in the hands of new owners and the Tombstone is worked by lessees.
 Near Paradise a 100-ton concentra- tor mill was started in November. The 20-stamp amalgamation and cy anidation mill built in 1910 at the Vul- ture mine, in Maricopa County, has been in successful 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 County, produce | gold-bearing ore, which is treated in cyanide plants. The former averaged nearly $65,000 in gold per month from the operation of it's 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 cyanidation.
 Two other gold mills, the Gold Grown and Ruth, were operated. In Todd Basin the Gro Plata mill is un- der construction. The new owners of the Southern Belle mine, in Pinal County, have ordered a 100-ton mill. The Huebabi mine, on Santa Cruz River in Santa Cruz County, was re- gently equipped with a 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 Monica and Rincon gold mines preparations were made to operate. The Tiger mine and mill, near Crown King, were operated steadily, producing gold bullion and lead concentrates. Grading was com menced for the cyanide mill on the Venezia mine, in Crook Canyon. In Yuma County, the Stafford Lane mill, near Vicksburg, was in regular opera tion, and also the North Star at Kofa.
 According to the preliminary figures prepared by the Director of the Mint which do not include statistics of eX- ports, the production of gold in Ari- zona, in 1911, was valued at $2,954,7 and that of silver was 1,594,42S fine ounces, valued at $S76,935 Final fig ures for 1910 gave for Arizona $3,413,- 200 worth of gold and 2,655, 700 fine ounces of silver, valued at $1 ABA, 100.
