Gold and Silver in 1911.

1910, according to V. c. Heikes, of the United States Geological Survey. The greater production of gold was at- trilu,able to the mining of siliceous lead ores, and copper lead ores, as the total gold output from copper ores re- mained about the same as in 1910. The principal producers of silceous gold ores were the Tom Reed, Gold Road, North Star, Tiger, Congress, and Vuture mines, in Mohave, Yuma, Yavapai, and Marcopa counties. There is promise of an increased out pu: 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 Yavapa County, on Lynx Creek and near Kirkland, were not successfully operated. Two dredging plants of the suction type were erect ed on the Colorado River, one in Ari- zona and the other near Pahreah, Utah Both plants are said to be operating and producing,
 The increased output of silver de- bends mainly on the increased produc- lion of copper and lead ores. All the old copper producers at Bisbee, Clifton, Globe, and Jerome maintain ed an output which com bined made nearly the same yield of ore as in 1910. The mines of the Consolidated ri- 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 prop critics. However, there was large increase in lead output and a some- what larger zlnc production, due to greater yield of lead ore in the War ren district of Cochise County and the zinc and lead ores of Mohave County. The largest silver producers of recent years nave been the Comm )n wealth and Tombstone mines. The output of silver diminished in 1911. The Common wealth is in the hands of new owners and the Tom bstone is worked by les. sees.
 Near Paradise 10 ,-ton coucentra. tion mill was started in November. The 2O.stamo am malgam ,tion 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 bea ring ore, which is treated in cyanide plants. The former averaged nearly 65,OOOS in gold per month from the operation of it's 2O.stamp mill in 1911, and the latter, with 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 grind ing and cyanidation.
 Two other gold mills, the Gold Crown and Ruth, were operated. In Todd Basin the Orc Plata mill is un- der construction. The new owners of the Southern Belle mine, in Pinal County, have ordered lO0-ton mill. | The Huebabi mine, on Santa Cruz River, in Santa Cruz County, was re. gently 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 Monica and Ripcon gold mines preparations were made to operate. The Tiger mine and mill, near Grown King, were operated steadily, producing gold bullion and lead concentrates. Grading was con- 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, 1908 and that of silver was l,594,4 4,42S fine ounces, valued at S46,935S. Final fig- upaS for 1Q10 pa fop n;,o~o
