proof of this in the last six months of high metal production in the face of a vafiety of discouragements. Wher+ ever outside interference has been | tabooed in the state, efficiency and eonfidence are higher and stronger in the mines, mills and smelters than ev- CT before. For full proof of which the production figures of the last three months provide indisputable evidence.
 Local Output curtailed
 Production in the Warren district 1 fell little behind in June. The Verde and Clifton-Morenci districts were also below the record made in May. Much the same reasons prevailed in all of the districts. These were the carrying ahead of more development, necessi- tated by inroads upon reserves in the previous two high pressure months. and the opening of the summer season with exceptional heat, the latter caus- | ing material increase in temporary lay-offs among working forces. Old Dominion and Iron Cap in the Globe district were exceptions, exceeding May output
 Making New Mine
 | Denn Arizona showed in the Warren district column with substantial m crease over its production in May. This ore is coming from the 1400 and 1900 | levels and is mainly won from pursuit of the development campaign the mine is under. On the 1900 level there has been found what gives promise of making a considerable body of com paratively medium grade ore. ayerag- ing between and 6G6 and correspond ing with Junction sulphides in appear ance and manner of occurrence. This ore was entered soon after the drift left the 1900 station and has not been explored far enough to provide line on it's probable extent.
 Rich Ore Expected The development is yet to reach a point where they are likel to pick up the rich ore opened on the 1400 and 1500 levels. They are going out that way with satisfactory conditions thus far attendant. The water is being handled readily with the equipment now installed and unless there should be an unexpected and material in- crease of water there will be no inter- ference with progress from this cause. Whether the real ore body Denn IS ex- pected to develop, and for which the upper levels show the way, will be ma terialized on the 1900, remains of course to be determined There has been much confidence that the level will more than prove up the best that has been anticipated, but at the same time it will not be cause for discour- agement if it shall be found necessary to go still deeper to reach the ultimate determination which is sought.
 New Mill to Start
 The Shattuck Arizona mill for the handling of the low grade lead-silver ores of the Shattuck mine. exceeding a million tons as thus far demonstrat- ed. is expected to be in operation this week. All equipment is in and it mere ly remains to turn on the power. This particular merely, however, IS a bit oversize. Arrangements for power have been broken into by al crippled independent plant, which is being de layed in securing additional equipment it requires. Arrangements of temper ary character have been made, how
 
 that power that company is able to spare will be turned over to the mill in a few days.
 More Lead; Less Copper
 It is probable that for time the operation of the mill will have effect of curtaining Shattuck copper produc- ton rather than increasing it. The lead output of Shattuck, however, will jump up smartly. Meantime the cop per output of Denn is growing and promises to offset the decrease in the total copper output of the district that Shattuck's change would otherwise bring. Last months combined copper from Shattuck and Denn made total of more than 100000 pounds. Shat tuck has but a single shaft and if 1t hoists enough of its lead-silver ore to keen, the mill going will have to cut down some on it's copper ore output. The latter course, however, will ena- ble more exploration and development in the copper ere area of the property of which there is need.
 Mill Construction
 Shattuck's mill has cost more than S300, ,O0O. A test plant trial of the pro cess the mill will cary out was sue cessful and it is expected that the new structure will turn over and go ahead with its work with even better results than the preliminary tests indicated as probable This remains to be seen, however, and the first month of oper- ation will be watched with much inter- est Capacity will call for 400 tons of ore the day.
 Cochise Shaft
 The Cochise shaft is now below the 1400 level and making rapidly to the 1900. It is as yet clear of ore and thus far has been through rock of very desirable character for working shaft purposes. Water to extent sufficient to supply the new Copper Queen con- centrator has not been found but it Is not despaired of. It is thought proba- ble, however. that they will have to go below the 1900 to get it. The work in the shaft is being done in a way that will allow of extensive operations from its levels whenever it may be under .aken.
