DEVELOPMENT IS RAPID AT HE
 KAY PROPERTY
COPP ER MINE, THIRTY MILES SOUTH OF MAYER. IS BEING WHIPPED INTO SHAPE AS QUICKLY AS MONEY CAN DO IT.
(By F. w. Bower.)

MAYER, Ariz., Nov. 25.-The most interesting thing in the mining game is the development of the first bodies of ore, when the prospect is passing into the state Of a mine, when the dimensions of depth, length and width, each day, multiplied into cubic feet, means tonnage. Some prospects develop into mines quick ly: others take months and some times years for their growth while many others die before they are born.
 The writer has just returned from another trip of inspection to the Kay mine. which IS located in the south ern portion O. the Black Canyon dis. trict, about thirty miles south of Mayer. Probably, no other copper mine on the Jerome to Phoenix" mineralized belt has developed so rapidly into a big mine as the Kay. While the mine has been a producer in a small way for a number of years, it was nothing beyond the ordinary until two months ago when the new
 management under George w. Long struck the new ore bodies on the 500- foot level
 The new work on the 500 consists of the main drift south from the shaft about 2lO feet Dense sulphide ore was first encountered in the drift 5 feet from the shaft and the breast of the drift is still in high grade COD per ore. At 75 feet from the shaft, crosscut into the footwall exposes l6 feet of solid sulphide ore averag- ing over percent copper and 6 feet of lower grade ore. South Of the shaft. g feet, a crosscut has been run 5 feet easterly which nearly cuts the formation. This is being run to test the width of the main ore channel which, in all probability, is at least 300 feet wide, as shown by the surface indications. The 5 feet of crosscut shows ore all the way which will average a little over 4 per cent copper and some gold and silver Sev- eral short cuts have beeen made on each side of the drift showing widths of ore from l3 to 20 feet assaying q to l3 per sent copper. The estimated tonnage of ore in sight south of the shaft between the $50 and the 500- foot levels is over S2,000,000.
 North of the shaft, so feet. a cross cut was run eastward 40 feet where sulphide ore was first encountered. foe all in ore with an average of nearly per cent copper and a small value in gold and silver The sample near the breast of the crosscut assayed s per cent copper The tonnage in the north workings is nearly equal to that of the south workings at the present time, with lesser amount of development work accomplished.
 All prospecting work on the 800 has been stopped for the present and sinking has been resumed to the 650 | foot level where extensive explora- tory work will be resumed No one | who has watched the development 1 of this remarkable mine will doubt ! for moment that the large bodies of | ore which have steadily increased in i width and value from a 3-inch string CT at the surface to the present large commercial bodies, will be found to ] be still larger and Of better grade on the next lower lever.
 There arc SIX or seven other promising outcrops on this Kay property which have been more or less prospected About 1000 feet north of the main shaft, is the Buck eye shaft, sunk lS0 feet. A cross cut at the 4O-foot level shows 10 feet Of carbonate schist and quartz, ore feet of which will average 46 per cent copper A complete hoist equip ment has been purchased and syste
 natic development of another ore body will soon be in progress with the possibility of opening up another big mine.
 The company plans to ship none of the ore but will make a mine first Il and then install a mill of the requir- ed process and capacity. It will un- doubtedly be an oil Notation plant for the ore IS for the most part a sul- phide that will concentrate 8 to 10 into l.
 The development of the large bod i' ies of ore in the Kay mine proves up another portion of the long belt of Yavapai schist which commences at the mines in Jerome and continues southward to the Kay, distance of about $ miles. Between the two extremes are other well known mines producing a daily tonnage from , depths of 200 to 1900 feet. The mineralized belt extends about 10 miles south of the Kay where it has , been exposed in several prospecting works.
 The three dimensions, depth, length and width of ore bodies, necessary to make mines seem to be making good , all along this great mineralized belt. Mining men will watch with great in- terest the new dimension" work at
