 KING or ARIZONA. The gold bearing property, known fer tine aS the GieGson. has been transferred to the King Arizona Mining and Milling Company, a cor porgtion organized nndcr the laws Of the Terri tory of Arizona, wlth a capital lzauon or ouOOUo0 sbares of a par value Of Sl each. This company owns four full claims she Homestake the lNlIS of Arizona, the Last Hope and the Aucho Bueuo. This district lies about thlrUy uFc miles due east of thd Castle Dome Land- ing on the Culoredo River. IL is north of the Gila River aud about 4e miles rom Mohawk Summit on the Southern Pacific Reiiroad. This is the nearest station on me railway There are several other locations besides those conveyed 10 the King e Arizona.
 The BoIuesialIe location covers the chiet workings up 10 this date. There is on this claim a strong Ysin of gold-ecarlng quartz This lode vein has three well-Inarked divisions CT layers. On the hanging wall there is a soft layer from to 3l9 inches wide, W hich averages about & 800 per ton in value. Next below this there is 6 middle layer or body oI quartz about @O inches thick, which will average about Ss0 to SlOG per ton in value. The remainder Of the vein. so far as it is exposed by the shaft, aver ages about S2i per ton. Test holes have been
 
 in ore. The shaft by which the exposure of the nature Of the vein has been made is POO feet deep and follows the dip C. the hanging wall a distance of 4u feet e2Stcrly and 30 feet westerly. These show continuity Of vein. having the same characters and values develop ed by the shaft. The hill rises rapidly both east and west of the shaft so that the height of backs on the lode above the drifts is greater than a, the shaft. At point about 30 feet west Of the shaft and on a level Hith the collar of the shaft the vein has been croSScut from wall to wall, showing it IS feet wide at that point. The ore in the crosScut is of about the same grade as that in the shaft. The croppingS of the vein may be followed for some 701 feet of the Home stake shaft to a second opening. known as The King of Arizona Shaft" This shaft is about 50 feet deep, and by means of drill holes the vein is shown to he II feet in width and has an aver age value of Sl0 per ton. At point 300 feet east Ot the HoineStake shaft Q tunnel has been made which crOSScuJs tine vein l60 feet below the sur face. Al this point the hanging wall vein is IS inches wide and has an average value Of $50 per ton. The tunnel then passes through 30 feet of vein matter running about B per ton, thence through feet Of ore carrying SIS per ton to the foot wall. The total distance from hanging wall to foot wall along this tunnel is 20 feet. A drift has been run along the foot wall to the Home stake shaft at diStaIsce of 800 feet. aEd tine average value Of the ore exposed is sl4 per ton.
