Mohave County miner and our mineral wealth., 1922-03-17
(By William P. DeWolf)

Oatman and Katherine, the two big gold camps of Mohave County, are growing favor in the investment cen ters of the country, according to state ments made by mining men from out side points who are arriving here in increasing numbers looking for pro- perties. The visitors assert that mon ey for mine work at Oatman and Kath- erine is becoming easier to obtain and predict that each of the camps will soon experience a mining excitement of proportions.
 At Oatman the vanguard of the pre- dicted rush has already arrived and includes men who have followed the mining trails from South Africa to the Arctic Circle. Many old-time Me- vadans are among those present at Oatman, and notably men who were prominent ad successful miners at To- nopah, Goldfield and other desert camps of a dozen or more years ago.
 The same conditions, in lesser de- gree, apply to the camp of Katherine, located about 15 miles north of Oat- man in the same range of mountains, and bearing the same character of ore as that at Oatman. At Katherine mining work is underway over rad jus of 5x9 miles, extending from the bonanza Katherine mine to the million dollar Gold Chain mine, and from the Adams mine, where free gold ore has just been opened east of the shaft on the 200-foot level, to Thumb Butte mine, where the management has de- ,velopment fund of $100, 0,00O:
 Diamond drills will soon be working at Oatman from the Oatman United property to the Casey-Jones group of the Oatman Apex Gold Mine, Inc, longitudinal distance of more than 3 miles. In the Katherine district the use of like prospecting mediums are being considered by the management of the Treasure Vault, the Gold Chain, the Adams, the Gold Chain Annex, the Katherine Extension and Revenue pro- perties.
 At the Katherine Treasure Vault the foundations for the machinery are be- ing laid and the plant will be erected and in commission before the close of March. This will be followed by shaft sinking to a depth of 300 feet, and there the management may decide to test the big Treasure Vault ledge for values at greater depth by means of the diamond drill. The shaft, dou- Accompaniment affair, will, however be sunk with a view to crosscuttlng and drifting on the vein at intervals of 100 feet. At the Gold Chain property the work of sinking is progressing satls- factorily with depth of 300 feet as the objective. There the well miner alized Gold Chain vein will be crosscut and developed both to the east and west of the shaft. A station will be cut in the shaft at a depth of 200 feet and after the width and value ot the vein has been determined at depth of 300 feet, it is probable that level vii be run and lateral development be done on the 2OO-foot level. The work to the east of the shaft on the lO0- foot level has served to block out ap- proximately $1,000,00O worth of ore and has demonstrated the vein to be 46 feet wide.
 A two-compartment shaft is being sunk on the Big Four property locat- ed near the townsite of Katherine. At a depth of 70 feet the bottom of the shaft is in a heavily ovidized dyke material, which at times shows cal cite and quartz replacement, thereon. The property is equipped with a plant of machinery and is being developed under the supervision of w. w. Wish- on, a mining engineer of national standing. Wishon is convinced that the Katherine district will prove to be one of the great gold camps of the country. As he has been associated at various times with some of the largest copper and precious metal mining ventures in the United States, MT. Wishon's op-
