MINE REVIEW
 FOR YEAR 1912
Was a Twelvemonth of Con- Stantly Accelerated Min ing Avtivity in Every
 Arizona District
sM WONDERFUL PROGRESS

IT
 For Arizona 1912 was twelve month Of constantly accelerating i mining activity, and the vast improve fments begun by the mining eompan les of the state during that period have lent an impetus to the industry that will make the present year q memorable one in the mining annals Of the southwest Arizona, already the leading copper producer. is re spending to the stimulus of high. priced copper in a manner that makes the red metal the most. interesting integer in the new states history i The so-called disseminated porphy ries," because of their enormous ton mage and the immense concentrating plants required to handle their mil I lions of tons of ere, just now are ] attracting most, attention; and among l these the Inspiration Consolidated Copper company, because of it's prog. ress of colossal construction, includ | ing a 1000 ton mill and two years of concomitant work, is making Miami 1 the present center of interest of Ari- zona's mining operations
 During the past year the Inspira- l tion Copper company and the Live Oak Development company merged ! their interests under the name of h. spiration Consolidated Copper com. pany. From the viewpoint of econo- my this coalition was deemed nee essary. The Miami Copper company s production for 1912 was about 33,- 100000 pounds of copper Its former estimate of 1S,000,oOO tons of devel- oped 2.5S per cent ore has been ma terially increased by recent drillings.
 Ray District.
 The Ray Consolidated Copper com pany produced about s, ,O0O. 900 pounds of copper during 1912 and expects to increase its production to a 7O.0aO .000 basis by 1914. Its 5000 GOO tons of developed 2.2 per cent ore incude the former Ray Central and Hercules properties, absorbed by the Ray Con. solidated last year.
 Among the low-grade Arizona cop per properties now in the develop ment stage the most promising are the Bagdad Copper company's ground in the Eureka mining district of Yav- apai county. the Southwestern Miami
  formerly comprised in the Copper Kings holding at Bisbee.
 Big Producers.
 Among the older copper properties the Gopher Queen, Calumet & Arizo- na Arizona Copper, Old Dominion, De troit Copper, shannon and the United Verde properties are the great pro- ducers,, and they have been turning out copper at a steadily increasing rate during the past twelve months and are enlarging their reduction plants that they may reduce stll! more ore in the near future. The Copper Queen at Bisbee produced about SZ,000,0 900 pounds last year; the Calumet & Arizona, also in the Warren district. came second with an output of 5S.000, 900 pounds; The Arizona Copper compsny's eight mines at Morenci, Metcalf. Longfei- low. Garfield and Coronda; turned out more than 36.O00,0OO pounds; the Old Dominion at Globe yielded 27.n00,- COG pounds: the Detroit Copper at Moranci shipped 2&00O, ,000 pounds. a1d the Shannon's contribution from that district was 1 yj00, ,000 pounds The gross earnings of the United Verde at Jerome during me past year approximated 5000 900, although the 1912 dividends were but S6 per share as compared with sS.25 for 1911. This decrease. however, was due to the increased expense of building rail road to the site Of the 5000 ton smelter now in course of construction. the driving of the Verde tunnel to. tan the ore at the depth of the smelt. CT site in the Verde Valley. and ac- companying expenses. The Calumet & Arizona company also is en.arging it's smelling plant at Douglas and will handle the Shattuck-Arizona ore, under a flve-year contract The latter company has about ] 1000. 900 tons of high grade ore blocked out, and when the C. A. snelters has been in July the present daily of 250 tons from that mine will be doubled.
 The Allis-Chalmers converters to be 7 used at the Calumet & Arizona and Arizona Copper compsnys plants G at the former and two at the A. O ] are of the vertical type nineteen feet I high and twelve feet in diameter. The shannon company blew in it's furnace in April
 The Old Dominion will continue en- larging it's reduction plant as during the past year. At the Copper queen smelter at Douglas the first of the new Great Falls type of converters, which replace two of the old barrel type. were blown October IS. Four more of these will be installed The i new. pioneer shelter ftbe Pioneer Smelling company was blown about the middle of 1912 It Is situated in Pima county on the Twin Buttes rail- road spur 21 miles south of Tucscn. I It came into being as a result of the dsTsand for smelting facilities of the Twin. Buttes, Mineral Hill, Helsetia. ! Tip Top and many smaller mines in that. district rhe SsaBsea Conscii.
