ARIZONA LOSES
 PRODUCING LEAD

Arizona, during the past year, tenn
 porarlly lost it's lead among the cop
 per producing states, being crowded
 out of first place by Montana But
 in spite of the low price of the metal
 the great producers of eopper-gold
 ores, such as the Copper Queen and
 Calumet and Arizona continued their
 profitable operations on a large scale,
 with satisfactory dividend. to the
 stockholders and maintained the pol
 icy of increasing the efficiency of
 their equipment and reducing the best
 of production.
 Hitherto copper mining in Arizona
 mas been limited to the great ore bod
 ies of copper gold-silver, which occur
 as replacements in lime or schist, and
 which will continue to maintain an
 increased production from both the present producing mines and many
 others in process of development But the past year witnessed - a change in this condition. by the in
 vestment by the public of several millions of dollars for the develop ment and equipment of the vast area of low grade deposits which exist in many parts of the Territory. These deposits are not limited to the Globe section of Gila county or the Ray Kelvin districts of Pinal county. They have also been found near Mineral Park in Mohave county, be- tween Hillside and Seligman in Yava- pal county, and at Ajo and south of Silver Bell in Pima county, all of which properties are in course of de- velopment. While none of these vast deposits have yet added to the pro duction of the Territory, they guar antee an enormous increase in the output of Arizona copper in the near future, and serve also to demonstrate that copper is not limited in it's oe- currence to a few sections, but is generally distributed throughout the entire Territory. The development of tonnage at the leading properties of this description has. in the past twelve months, been truly remark able.
 The Ray Consolidated, which, at the end of 1908, only claimed the developed ore tonnage of about g. 100000 tons, has now nearly 42 .0O0,- 900 tons proved by churn drills, and is rapidly opening up this ore, and converting what may be regarded as an estimate, into a possible tonnage, and it is believed that there will be fully 1O0,OOO,OOo tons eventually developed in the mine.
 Other properties. such as the Ray Central, Hercules and Gila, in the | same district. have demonstrated in their respective properties, 100000, 100000 and 12,OOOOOO tons.
 The Miami, near Globe, increased | its ore tonnage from about 4,500,0O0 to over 15.OOO,OOO tons, actually proved to be available for treat ment, with unknown possibilities of largely augmented tonnage. In the Inspiration, Live Oak, Cordova and other properties in close proximity to the Miami, there have also been opened up immense bodies of dissem- mated copper porphyry ores of pay able grade.
 The year also witnessed a distinct and most substantial revival in gold mining, the industry, which in the early days, was first responsible for attracting attention to the mineral re- sources of the Territory. The great gold belt of Arizona commences in the northeast part of Mohave eoun- ty, and runs in a southeasterly di- rection along its western boundary, through Monave, Yavapai and Yuma counties, with important branches in Maricopa, Coehise and Gila counties. This revival has not been limited to one district alone, but has been dis cernable in the San Francisco dis triet of Mohave county, of which Gold Road is the chief camp, the old Weaver district of Yavapai eoun- ty. of which the Congress camp is the best known; the Vulture district of Maricopa county. tine Kofa and Polaris sections of Yuma county, and the Tombstone district of Coehise county. All of these exhibit marked activity and the companies oper- ating them are demonstrating that low grade, free milling ore can be proftably mined. For many years past the gold of Arizona has been principally produced as a by-product of its great copper mines, but the
