Mohave County miner., 1912-01-06

The Globe Miami district produced about 40,000,00O pounds, compared with 27,6O0,O00 pounds in 1910. The large increase is due to the production from the Miami area. The first unit of the Miami mill started in March and successive units later, five of the six being in operation at the close of the year. Large additions were made to the ore reserves of the district, es- pecially by the Inspiration and Live Oak companies, and important devel. opment work was carried on by other com panies. Development was also active in the Globe end of the district. In the Jerome district the output of the United Verde mine will show slight decrease from the 3S.660,00 pounds produced in 1910. The de. crease was due to difficulties with the old shelter. The United Verde Co. has new smelling plant under con. struction.
 The Humbo shelter of inc Con. >olidated Arizona Copper Co. was operated till November and then clos ed.
 The Mineral Creek district entered the list of active producers during the year.

The de. celopment and blocking out of ore was continued, especially by the Ray Con. ,olidated and Ray Central companies.
 MONTANA.
 The copper production in Montana will probably fall lO,OO,,O) to l2,OOO, 100 pounds short of the output of 295,- 900, ,OO0 pounds in 1910. This decrease 8 due to the policy of curtailment adopted by the companies in the Butte district
 Extensive development was carried m in the Butte district and especial attention was given to improving the mine equipment of the units compos ing the Anaconda Copper Co. This included the extension of the use of 'lectric and cOmpressed-air power. i'm prOvement in ventilation. etc. These improvements are expected to mater ally reduce the cost of producing copper.
 MICHIGAN.
 The production from Michigan. 'anking third among the copper-pro lucing States. ill probably show a decrease of about 5,O0O,OOO pounds rom the production of PLACE. .O00 pounds in 1910. This decrease can he attributed to the relatively low price ,f copper, which caused some com oanies either to suspend operations 0, 70 produce below their maximum ca oacity. No unusual development, l year, though several mines that havt been under development made small productions
