Mining Operations in Yava- pal County Are Soon to Be Advanced by the Construc- ton of Underground Work.
PLANS ARE NOW COM
 PLETE FOR START
Great Things Are Expected of Tunnel Which Will Pen- citrate Mountains a Matter of 12,000 Feet.
(By William P. De Wolf.)

! PRESCOTT, March Is. Mining operations in the Bradshaw mountains are soon to be furthered by a tunnel project of similar magnitude to the extensive development. drainage and transportation tunnel enterprises of the Cripple Creek district of Colorado. Plans to that end are well advanced, that they will soon reach the construc- tive stage. Preliminary surveys have been made, typographical and geolo. gical reports have been submitted and the necessary capital has been sub scribed.
 The Bradshaw mountains are rich in gold. silver, copper, lead, tungsten and zinc ores. The mines of that sec tion have for many years added gen
 erously to the mineral wealth of Yavapai county and have prominent place in the mining history of Arizona. The proposed tunnel is to be utilized as means for opening these mines at depth considerably in excess of their present lowest levels. Dr. r. A.
 Wheeler, of Chicago, is the dominat- ing factor of the tunnel enterprise Associated with him are capitalists of that and other cities of the Middle west. pr. Wheeler was a very sue cessful mine and lease operator in Goldfield some years ago. and a num- Der of the men who are associated with him in the tunnel project shared in his mining successes at Goldfield and elsewhere in Nevada.
 For some time past. until recently, engineers and others in the employ of the men behind the tunnel enterprise had been making an extensive but un- ostentatious examination of the topo- graphical, geological and mineralogi- cal characteristics of the Bradshow mountains. These reports were from time to time forwarded to headquart- CTS in Chicago, and were, about three weeks ago, supplemented by the per sonal report of Dr. Wheeler. The lat ter came here for the purpose of checking the reports of his subordin- ates. Upon his return to Chicago the financial end of the enterprise was definitely arranged.
 Before leaving Prescott pr. Wheeler outlined his plans to me and stated they would be in operation by early summer. In this country of short winters and abbreviated springs. the statement is construed to mean that actual construction work will start not later than May 1st. By that time the last. vestige of snow has disap- peared from the timbered slopes of the Bradshaws and they are again ac- cessible for ten-month period. In speaking of the tunnel project Dr. Wheeler expressed himself as being thoroughly satisfied with the ore yielding possibilities of that section. and voiced the opinion that at greater depth. larger and more generally min eralized ore bodies than those at pres ent under development, would be en- countered.
 As outlined, the Wheeler tunnel will penetrate the Bradshaws for an ap- proximate length Of 12.000 feet and to a maximum depth of 1900 feet. Its course will be from east to west. starting at a site about one mile be- low the camp of Crown King and ter minating on the Wild Flower group of claims on the opposite slope. lt is the purpose to utilize the bore for transportation. for exploration anl for drainage. That is to say, the tunnel will conform in general usage to the Roosevelt and the other service tunnels of the Cripple Creek district. 1
 Through medium of the latter the mines of the Cripple Creek district are being drained and explored at grest depth and the ore bodies on their lower levels developed. In addi- ton the tunnels are utilized for tran sportation purposes at an expense much less than that entailed by moy-
