copper mine about six miles northeast of this place for over two years, the ore being a chalc0pyrite copper with small amount of silver. An oil flota- tion mill has been used to treat the ore, which has an average capacity of about 150 tons per day The report shows that about g0,0o0 tons of ore have been millcd and 922 tons of high grade have been sent to the shelter which shows a total production of close to 5000000 pounds of copper representing recovery of nearly , per cent It has been profitable to treat ore as low grade as 214 per cent.
 There are in reserve. according to Mr. Winchel about l00,0Q0 tons of 3 Der cent ore and about 150001 tons of lower grade, all above the 600-fOoi level. The mine has been developed on the strike of the ore about HOO feet. On the strength of this en- ! sineer's report, work is in progress on a new three compartment shaft which will reach the I50 0-foOt level about the first Of June. This will give the mine an increased tonnage so that new mill of 350 tons or more will be war ranted. The flow sheet win probably be the same as in the present mill for the oil flota ton process has proven 10 { be especially well adapted to this class of ore.
 The success of the diamond drill method of exploring new levels of a i mine in search of ore bodies has been i proven in this mine The Cannon Brothers have drilled about so holes in the past seven months. The holes are run as CrOsscuts every 100 to 150 feet apart from drifts which follow the formation in a northerly and southerly direction. One lense of ore was struck only two feet in from the drift by the drill and another large ore body was found .5 feet away from the drift which had been passed by in old work ] ings. This method of prospecting has been found to be much cheaper and ;nOre effective.
 The WincheH report is of especial interest 10 mine owners of the Jerome to Phoenix belt, for it wds made in ! a developed, producing mine where the ore lenses. faults and general forma l ton could be followed. A portion oi the report states: The oxidized zony extends to a depth of about 60 feet Beneath this, there is a very shallow ] zone of secondary enrichment and be- low that the ore is primary. The geo . logical character and probable genesis of these ores is such as to indicate in- definite downward extension and there is every reason to believe that future developments to great depth will dis close the existence of even larger orc bodies than those now being worked.
 The developments prove the pres | ence of a valuable series of ore lense. and indicate the existence of a perma- nent mine. The extent of mineraliza
 tion and quantity of ore which may be developed in the future are prob lematical, but it is certain that the mine is not yet developed to it's ful producing capacity and it's possibilitie. are attractive"
 Word has been received from tn, office of the Copper Queen company in Texas, to the effect that an oil flo
 tation mill will be arranged for at tn. coming annual meeting. This mine i, east and adjoining the Binghamton The Big Bug company is sinking shaft on a very promising vein abou

 w. D. Mahoney, general manager 0
 the Western Copper company, is ex
 pecting to have work started on large scale at the Patton property, als, south of the Binghamton mine. Ex. cellent ore of shipping grade is bein: developed in the Little Egypt mine near Mayer.
