ARIZONA MINING
 ACTIVE IN 1910
V. c. Heikes, of the U. 2. Geological Survey, Has
 Issued Years Resume.
GREENLEE COUNTY AT TOP
The Three Big Companies Averaged 6, 1000, GOO Lbs.
 Copper Per Month.

Averaged 6,O0O, 900 Lbs.
 Copper Per Month.
 Statistics compiled by V. c. Heikes of the United States Geological Sur vey, indicate that mining in Arizona was decidedly active in :19lO. The copper output of the State, which greatly exceeded that of Montana, fell below that of 1909. but was near ly 297, 100000 pounds, which shows that the large smelters were doing steady work. The copper ore mined Tn Arizona supplies about one-third of the States usual gold output and two-thirds of it's average production There were marked changes m the gold output of the State, which were due almost entirely to activity at the Gold Road and Tom Reed mines, in Mohave County. The final figures will probably show a larger prOduc- ton of gold than for any year since 1906, when the total was I43,0O0 ounces. The silver production was over 2,5OO, 900 ounces, or more than the output of 19O9 The lead output was probably less than that of the preceding year, when it was slightly over 5000, GOO pounds. The output of zinc, which in 1909 was equivalent to a recovery of nearly 6,OOO,OOO pounds of speIter, may have reached 100000 pounds in 1910.
 CoCHISE COUNTY.
 In Cochise county the Copper Queen plant was producing at the rate of B. 100000 pounds of copper month in January, exclusive of that derived from Mexican ore. In the later part of the year this record was not up- held, and in December work was started on two new reverberatOry furnaces and McDougall roAsters. At the Calumet and Arizona smelter more than 4,OOO,OOO pounds a month was being turned out, although the plant was not run at full capacity. During the period of curtailment in the latter part of the year the blast furnaces were enlarged to a total capacity of 5000 tons day. Ship ments from the Shattuck mine in creased from three to five cars of 17 per cent ore being sent daily to the Copper Queen smelter. The 2OO-tOn mill at the Commonwealth mine at Pearce was destroyed by fire in April, but in November another cyanide and teaching plant of 126 tons capacity was in operation. The fight against water continued at the Tombstone Consolidated property, where pump ing was carried on at the rate of G., 5O0,OOO gallons day. From ths To- cality the Royal Guards Mines Co. was said to have done some shipping.
 CHA COUNTY
 In Gila county the old Dominion smelter turned out more than 2,225,- 900 pounds of copper a month, which is somewhat less than it's full capa- city. The Arizona Commercial oper- ated its mating plant for four months treating POO tons or more day. In May the plant was closed and devel- opment continued at the mine. The operators of the Warrior mines ship ped at the rate of 100 tons day to Fl Paso and Globe, and the Superior and Boston was shipping 50 tons of 9 per cent copper ore a day An un- usual amount of work was done by churn drill as well as by drifting on arge low grade copper deposits.
 GRAHAM COUNTY
 In Graham county the Shannon, Arizona Copper and Detroit plants were collectively averaging 6,0OO,00O pounds of copper a month.
 MARICoPA COUNTY
 At the Vulture gold mine, in Mari copa county, the old mill was run ,alf the year, and the first unit of the new stamp mill, with cyanide plant, was in operation in August.
 MoHAvE COUNTY
 Great progress was made in Mo have county in production and mill building From the GOlconda mine rich zinc ore was being shipped at the rate of about 800 tons month and a concentration was being con structed The bullion from the 200 ton mill at the Gold road mine amounted to $50 ,OOO or more a month. In November the mill had been en- larged to treat 300 tons. The iO stamp mill as the Tom Reed was treating 8 tons of $40 gold ore day. With the addition of new tube mill the tonnage treated was increased in the last months of the year. The Banner and Tennessee mines were again brought to a shipping basis by the United States Smelling x Refin- ing Co.,, which has constructed con centration plant at the Needles smell ter for the separation of lead-zinc ore New mills were completed or in course of construction by the Frisco M. & P. Co, Arizona Gold Mining Co and the Expansion, Gold Crown and
