PROFITABLE WORKING OF GOLD AND SILVER PROPERTIES DRAWS
 MINING MEN TO KINGMAN FIELD

can do it.
 With the solving of the treatment problem the Dudley interestes. as they are called. erected a modern, electri- cally driven reduction plant near the collar of the C. O. D. shaft at an ap- proXimate cost of $20O,000 and equip ped the mine itself with electrically driven machinery. In addition to this comfortable quarters were built for the miners and an easy-graded road was constructed from the mine to the main highway to Kingman. All of the camp buildings are lighted by e1ec- tricity and all of the top work. such as tool sharpening and the like, is done by electric devices. The mine and mill plant is modern in every particular and is one of the most ef. ficient ever erected in the mining areas of the west.
 The mill has an ore reduction ca- pacity of 125 tons daily and went reg ularly into commission on March 15, last. It is now handling in excess of 100 tons of ore a day and is saving better than 90 per cent of the values. Forty tons of concentrates. having a value of from S2O0 to S240 a ton. are being shipped to the shelter at Mid vale. Utah. at six-day intervals. The precious metal content runs about two ounces gold and the balance sill yer. The ball type mill, with regrind- CTS, classifiers and Notation process, is used in the reduction of the ores. This mine and mill force at this time totals 65 men and is to be increased to so men not later than May 1.
 Conditions Are Good
 Conditions in the mine working are on par with those at the surface. Above the 400-foot level the value of the ore in sight is estimated at bet ter than s1,000.O00. On the 4OO-foot level the east drift Is out from the shaft distance of 450 feet and is in ore all the way. The same condition prevails in the west drift, which has a length of APO feet. Between the two heading the vein has an average breadth of four feet and an averave value of BPS ton-S22 silver and S5 gold. The vein shows true and strong from surface to a depth of 400 feet. and there is pronounced increase in values at that depth. In fact the ore in the bottom of the headings on the 4OO-foot level is the richest thus far opened in the mine This condition indicates that even richer ores will be found when the vein is entered on the fifth level.
 The shaft has been driven a depth of so feet below the 4OO-foot level. following the ,footwall of the vein. and while not in the ore shoot is vet carrying values. The 5OO-foot ob- iective will be gained in few days. There d station and pocket will be cut prer aratory to drifting east and west along the course of the vain. Prosecuting and raising attend this work for the purpose of blocking out the ore between the fifth and fourth levels. This work is expected to add largely to the ore tonnage in sight and will probably necessi'jte an in crease in the ore reduction facilities.
 Daily Tonnage Good
 An idea of now closely ore produc- tion is competing with ore reduction is gained when it is stated that all of the ore now going to mill comes from the development work only. No crosscutting is being done at this time and no raises are being driven. Yet the daily tonnage of ore is crowding the capacity of the mill
 Dudley and his associates have been operating mines in the sections 'ributrary to Kingman for the past four years. During that time they have spent more than a million dol lars for mine development and ma chinerv. Their holdings are exten- sive throughout the Cerbats' and elsewhere and have an aggregate val ue running into the millions. They have financed their mining ventures without assistance from others and have ample funds for the carving out of their future development plans. There are five men in the Dudley syndicate all customers of great wealth. and they are probably the largest individual mine operators in
