Mohave County miner and our mineral wealth., 1921-12-02
By William P. De Wolf

Mine development in the north end of the Katherine district on a scale comparable to that now being done in the south end of the district, is as surred by the purchase of the Sun beam group of claims, located in the vicinity of the Gold Chain mine, by the Silver Hills Mining Company. Confirmation of the purchase has been made officially, and states that the very substantial fund in the Silver Hills treasury is to be devoted to de- velopment of the Sunbeam property at depth. Local mining men interpret this to mean that program of deep development, similar to that now under way at the bonanza Katherine mine, will soon be in force at the Sun beam.
 Harry G. Stimler, of Tonopah, New ada, who is heavily interested in the Silver Hills company, and who was instrumental in optioning the Ingalls, mine at Tule Canon, Nevada, to the Silver Hills company, will arrive in Katherine in few days to look over the Sunbeam group and outline ten tative plan for it's development. Stimler has been identified with w. J. Loring mining interests in Nevada for several years. He was one of the first to locate claims in the camp of Goldfield, and since that time has been identified with all of the mining rushes in Nevada. Stimler is an ex- perienced prospector with an almost uncanny faculty for nosing out high grade ore.
 George Probasco, who, with his part ner Burt, interested MT. Loring in the Sunbeam group, returned here from San Francisco few days ago. He states that it is the purpose of the Silver Hills Company to equip the Sunbeam with the machinery neces- sary for driving shaft to depth, and that the plant will be on the ground by the time the site for the shaft has been selected. This shaft will prob ably be sunk at some geologicaly ad- vantageous point between the two we'll mineralized veins that cross the property. Each of these veins has a width of about 75 feet and carries gold values as high as several hundred dol lars ton. The veins are located about 400 feet apart. Superficial de- velopment of them, by means of open cuts and the like, indicate the ore to be similar in character to that opened in the Katherine mine, where between two and three million dollars worth of free milling gold ore has been blocked out.
 At the Gold Chain mine the estimat- ed value of the tonnage in sight at and above depth of 100 feet is $1 1,00O, ,O0O. The ore is replica of the Katherine ore and is reported to be increasing it's gold value as No. 8 crosscut north on the 1OO-foot level is driven fur ther into the vein. At this time the cross-cut has length of 444 feet and the hanging wall of the vein is not yet in sight. Superintendent Nourse, from measurements taken of the vein at surface and nominal depth, believ- es the ore in No. 3 crosscut will pre- vail for width of at least 60 feet. This width would be analogous to that in No. 2 crosscut north, where 56 feet of ore is showing. A plan for the development of the Gold Chain vein on a more extensive scale, both on the 100-foot level and at deeper levels, is to be considered by the company directorate in the immediate future.
 A crosscut is being driven to the south in ore at a depth of 55 feet in the Treasure Vault shaft. The shaft entered the casing of the vein on its dip at depth of 45 feet, hence it required but nominal amount of crosscutting to enter the vein proper. The ore is complete quartz replace ment of the calcite, and is identical in appearance with the ore opened nearby in the Katherine workings. M. B. Dudley, general manager of the property, is completing arrangements
