LOCAL MINES SHOW IMPROVEMENT IN
 GENERAL
INDUSTRIOUS INCREASE IN ORE DEPOSITS IN SIGHT AT
 MIAMI MINES.
NEAR FOURTEEN MILLION TONS
OTHER PROPERTIES IN DISTRICT REVIEWED, ALL SHOWING FIX
 CELLENT CONDITION.

The local mining situation continues highly satisfactory. The operating |companies are all busy and there is growing confidence in the future of the district. The building of the railroad from Globe to Miami is having an excel. lent effect, is it is realized that rail. roads are not built unless there is as- surance of enough business to yield reasonable revenue on the investment; and there is no one who has any know. ledge of the Miami section, of it's enor- nous copper deposits and the efforts being put forth by strong companies to develop them, who does not look for ward to unexampled activity and in crease in population in that part of Globe district. There are mining men who predict that the Miami section in 8 very few years will bncome one of the greatest low grade copper districts in the United States.
 Miami Sulphide Deposit
 The Miami Copper company, which a year ago had 2,50O,000 tons of ore in sight, now has l3,5OO,000 tons blocked out, with the probability of q much larger tonnage being developed. With in year the Miami company expects to be treating 2,000 tons of ore daily, from which recovery of 45 pounds of cop per per ton would insure 32,000,000 pounds per annum. The ore already placed in sight is sufficient from which to supply 2,G00 tons daily for more than eighteen years. In view of this and the possibilities following further developments, it ssems highly probable that the company will ultimately make provision for the treatment of 1000 tons of ore daily. The railroad should be completed to Miami by July I, at which date active construction of the Miami company's coneentrator will be- gin.
 The Inspiration is another property which gives promise of developing into a great mine rivaling the Miami, which it adjoins on the west. The ores of the Miami and Inspiration are of the same character, being mainly sulphide in the form of chalcocite disseminated through schist, and carrying from 2 per cent to 3 per cent copper. As re- gently stated in an eastern financial paper, fivc years ago mining men would scarcely look at & copper mining prop osition the ore of which contained less than 3 per cent copper, the Lake district alone excepted; now several of the large producing copper mines in the west are quite low grade, such as the Utah Copper, Boston Consolidated, Ohio Copper, Nevada Consolidated and Cum berland- Ely The'ores of the Utah Cop per company average less than per cent copper, and in fact the ores of all the properties mentioned run less in copper than the Miami and Inspiration ore. The Ray Consolidated is another Arizona property the ore of which is similar to that of the Miami, although not carrying so much copper
 Developing Big Ore
 The Inspiration, which was taken over three months ago by the Gum Thompson interest, is being developed under the direction of Geo. E. Gum as general manager, and Henry Krumb as consulting engineer. The surface show ing on the Inspiration is far better than on the Miami, and the develop ment work done by the former owners placed l,50O,oOO tons of low grade sui- phide in sight and there is reason to believe that a tremendous tonnage will be revealed by the work to be done within the next year.
 The Keystone is another property in that immediate section that is proving up well, sulphides having been devel- oped by churn drill tests and in shaft that is being sunk. The Keystone is under bond to the General Development company, controlled by the Lewisohns. Live Oak and Eureka
 Adjoining tho Keystone is the Live Oak, regarded by many as being one of
