 PRESCOTT. AriZ.. Aug. 19.-Miner- al conditions throughout Yavapai county continue to improve as new properties are developed and old mines are opened at greater depth. The one showing at present is better and more general than ever before and assures a larger output Of pre- cious metal the current year than has attached to this county since the palmy days of silver. Copper. the king of metals in Yavapai county. is being mined on an eyer-increasins scale. For the siX-mOnth period end ing June 90. last the output of the red metal was the greatest in the his tory Of this section; and that output. judging by the record established dur ing July and to date in August. will be largely exceeded by the output during the latter half of 1916. The output of gold the current year will exceed somewhat that of past years. while the output of silver, it's sister metal. will be greater than in a num- Der of years. The outputs of tung- sten. lead and zinc will also be greater this year than ever before.
 Among the properties which bid fair to add to the output of copper from the Jerome field-now so gener- ously sustained by the United Verde. United Verde Extension and Copper Chief mines the Pittsburg Jerome. In early August dispatches from here announcement was made of a strike of copper ore in that mine. Recent in formation disclOseS the fact that the vein. while narrow a, the present point of development. is widening as the drift is extended The discovery was made in a drift from the west crOsscut on the 50G-ioOt level about 70 feet from the shaft. The first sam pies taken gave returns of II per cent copper and some gold. Samples talk en after drifting on the vein a short distance gave returns of 22 2S per cent copper and values in gold. The vein pitches away from the shaft and gives ind cations of becoming an ore body of considerable size. A winze has been started in the vein and to it's present somewhat nominal depth has carrying high pay values in copper and some gold.
 Will Sink Deep Shaft.
 The directorate of the Venture Hill company. owner of valuable acreage in the Jerome copper belt. has author ized the purchase of mine machinery and the sinking of a 3-cOmpartment shaft to a depth of 500 feet This ac- rfva ,r-fFh [ h.a ma Tf ff tions of John s Riley. the engineer who has been in charge of develop ment since reorganization of the com pany was perfected about three months ago. Pending the installation of machinery. work will be continued in the tunel The face of the latter continues to show favorable mineral indications Assays taken on ore mined in an old shaft on the property gave returns of S27 copper and Sl44 silver per ton The tunnel is being driven in the dike from which these values were obtained and through it's medium determinations for the deep shaft will be made.
 Gold values Of SS3 51 and silver values of S7OS per ton are being Ob- lalueu at nOuilndi utptu ih tue HtN shaft being sunk at the mouth of the tunnel on the Fairview group Of claims in the Crown King country. Sulphide ore is also exposed therein. The objection of the shaft is a depth of 200 feet. where the ore body will be crosscut and developed. Montana mining men are backing the venture They express themselves as being well satisfied with the showing and with the property's future prospects. The Crown King field has for years been notable for its output of high grade gold silver Ore-values in considerable tonnage running from S250 to a high as S1 .OOO per ton.
