Bisbee daily review., 1916-02-27

of it's property upon an extensive and thorough scale. It has installed at its new vertical double-compartment shaft on vein No. l a 25 horsepower gasO- line hoist 320 cubic foot compressor and 52 horsepower gasoline engine. Three shifts of miners are being em- ployed and the shaft has already gain ed a depth of 75 feet. While it is the plan of the management to sink to depth of 800 feet, a crosscut to com pletely intersert the vein will be run at the 300-foot point when it is reached.
 After this has been accomplished the shaft will be immediately continued to tended at that depth and also on the 4OO-foot level. The vein stands al most vertical, dipping but slightly to the northeast, and trends east and west.
 Carter.
 The management of the Carter con- tinues to give its attention to straight ening and repairing the main incline shaft from the collar to the bottom or 250-foot level in preparation for it's continuation to the 5O0-foot point. It is expected that sinking operations will be resumed within the next few days Exploratory work in the vein on the 25O-foot level has been tempo rarily suspended.
 WaIlapai District.
 | G. s. Holmes of Salt Lake City and associates are employing 15 mines, di ! vided into two shifts, in the operation , of the midnight property near the town of Chloride. in the Wallapaid district, whic hthey recently took over from
 Kean and John St. Charles of King
 man. They are at present devoting
 their energies to extending a west
 crosscut on the 200-foot or bottom level to a ledge which on the 100-foot level shows width of 57 feet and give average assays of so per ten in
 zinc, gold and copper. As soon as the
 ore body is proven up on the 20O-foot ] level, the shaft will be continued to
 a depth of 300 feet Following a re-
 cent visit to the property, MT. Holmes
 announced that as soon as work al present outlined is completed he will
 install a new equipment of machinery
 and erect a large concentrating mill on
 the ground.
 Golconda Extension.
 Drifting north continues nthe 40U

 mine, for the last 40 feet, the drift
 which has a total length of 95 feet has been advanced on full face
 of quartz carrying milling values. Tho
 management plans to place the 30
 ton concentrating mill on the proper
 ty in operation within the next sixty days.
 CopperfieId.
 Exploration of the property on the Copperfield Porphyry Copper Company
 at Cross Springs by drilling operation.
 is going steadily ahead, attended b, highly satisfactory results Drill hcl No. 3, after passing through 35 feet ct
 over-burden, penetrated material as saying ore one per cent copper. Ter | struck and at a depth of 59 feet tho |. drill is cutting ore that is steadily i'm proving in copper content. Drill holC No. which was put down 6 feet, ha. has proven up 5 feet of ore carryin. from l to per cent copper, while hol, . No. l, put down a distance of 5 feet showed 21 feet of ore averaging ? l.. per cent before the drill became wedg ed in nest of exceedingly hard quart, woulders which necessitated the aban
 donment of operations at that particu
 lar point on the property. The eas
 crosscut tunnel, which is being al vanced into the deposit at shalloy - depth depth has exposed approximate 1, " 150 feet of ore of good grade. IT ? management estimates that the devel , oPment work thus far performed Ina - proven up 2,00O,000 tons of 3 per cen !, copper ore.
