 mined for a considerable distance. The site of the shaft on the adjoining Katherine Extension property was de- termined by an underground survey of the Katherine workings. At a depth of 100 feet the Extension shaft passed out of the overburden of wash into solid formation and at depth ot zOO-feet entered what appears to be the casing of the Katherine vein. The shaft will be deepened an additional 50 feet, which, allowing for the topog- raphy of the country, will give it a depth corresponding to the 200 level in the Katherine mine, and there a crosscut will be driven to the north east continuation of the Katherine vein. Stringers of quartz in the shaftIprobably feeders from the vein yield gold values as high as $10 a ton.
 The high grade character of the ore exposed on all the levels in the Katherine mine, and more especially the recent discovery of high grade ore on the 4OO-foot level, has served to quicken mining effort at a number of properties, other than the Katherine Extension, which are reasonably cer- tain to carry the northeast continual t;on of the Katherine vein. At the Gold Chain property, located approxl- mately three miles from the Rather inc mine, the shaft is nearing cross ledge, on it's dip, which appears to in tersect the Katherine vein. Air drills are expediting the work of shaft sink ing. The Gold Chain cross-vein out crops a height of 200 feet and is es- timated to carry 100000 tons of brec, ciated quartz of an average value ol $6 gold ton.
 At the Sunbeam, (W. J. Loring) property, adjoining the Gold Chain on the north, a number of cross-ledges are being tested as a preliminary to the installing of machinery and the sinking of a deep shaft. At surface and shallow depth the ledges on the Sunbeam carry gold values as hlgh as s1OO a ton. Nearby the Sunbeam property a plant of machinery is be- inc erected on the Adams group. Up on completion of this work new shaft will be sunk to develop the big vein showing at surface. The cross cut run at a depth of 30 feet Tn a prospect shaft on the Adams group opened 40 feet of ore ranging m Va'1e from s3 to $7O gold a ton. A. H' Cushman, and associates, operating as the Union Pass Mining Company are preparing to develop the Big Four am Cushman Fraction groups ad1oihins inc Gold Chain property on the south' Plans are also being made to develop the Iris group adjoining the Snnoea.h nroperty. The Iris was recently "p toned to E. M. Mcdonald and was IT. nanced by him in New York.
 Two shifts of miners are eXtenains :. dr;ft to the south along the root wall of the big vein in the k'aaslae mine. This work is being done on ',.e 10O-foot level and is preliminary ~ extended development of the mlne at dantb when the lower workings nave heen unwatered. In former years thc Roadside % is said to have produced a considerable tonnage of high grace gold ore from surface to aepIh Il zoo feet-the present lowest level' The property is located about f"ar miles east of the Katherine mine ana is being worked under bond by the Arizona Rand company. Where open ed on the 1OO-foot level the vein is credited with a breadth of s5 feet and is said to carry milling grade ore Nearby the Katherine mine, work mas as been started on the Treasure Vault group of claims. The acreage carrles several well-defined ledges.
