 County
FORTY MILLION POUNDS
 OF COPPER LAST YEAR
Completion of Customs SmeIt- CT at Humboldt Marked the
 Most Important Event in
 Mining Industry for the Year

The mines of Yavapai county, Ari- zona, produced in round numbers s9,000,000 in precious metals in the past year. In this list of values, cop per heads the list with a production Of 40,000,0G0 pounds; gold amounting to S1,750,000, was produced from the lodges and placers; silver 500,000 ounces; and lead and other metals amounting to s200,000.
 The completion of the custom smelting plant of the Arizona Smelt- ing company. at Humboldt, sixteen miles east of Prescott, writes a Pres colt correspondent, marked the most important event to the mining indus try for the year. This plant is erected on the site of the Val Verde shelter that was destroyed by fire in the year 1904. The location is an ideal one from every standpoint, being on a branch line of the Santa Fe railroad and centrally located in regard to the producing mines of the country.
 The plant consists of two reverba- tories of 90 tons daily capacity; sixty ton electric crane; six converters; three sets of Edwards roasters, two
 
 pattern: two sets of Sterling boilers and two large centrifugal pumps
 A concentrator of 600 tons daily, ca pacity, using thirty-two concentrating tables, four crushers and three sets of rolls; the sampling mill is equip ped with two 30-ton crushers, two 3OO- ton rolls and 300-ton finishers; three automatic samjlers and mixers, one ha1 bins to crushers, 100 feet long and eighteen inches wide. The receiving and storage bins have capacity for 5000 tons of ore. The oil tank for holding oil for fuel has a capacity for 100000 gallons. In addition to ali this the company has installed three large electric generations for trans hitting power for the operation of the Blue Bell and De Sota mines, several miles distant.
 The Santa Fe railroad has made liberal rates on ores from all points on its line in Arizona to this plant, thus iusuring bountiful supply of ore to keep the plant running steadily
 While the completion of this great smelting plant means wonderful in crease in the development of the min ing resource of Yavapai county, the fact must not be overlooked that other reduction works for the treatment of ucstom ores were also completed dur ing the past year that are of vast i'm portance to the further development of the mines-the Rigby Reduction Works-at Mayer, this county. This plant has capacity for the treatment of 200 tons every twenty-four hours. The votilization process is used to extract the values from the ores. Agents of this company are now in the field making contracts with the min CTS for their product
 The United Verde mine produced about 36,000,000 pounds of copper and enoguh gold and silver besides to fur nish a kings ransom This old standby of Yavapai county has pro, duced millions of dollars in the past in copper, gold and silver and will continue to do so for many years to come. -.-... /. % ..--
 The Congress mine, the property of the Congress Gold company. has been working to its full capacity. This mine has produced large amount of bullion. The holdings consist of a great many full mining claims and ss the vein is known to continue to great depths. work bids fair to re- main active for many years to come. The deep shaft on the Congress vein some 1000 feet, demonstrated to the people of the mining world beyond any question of doubt that the mineral caring veins In Arizona reached great depths ana carried the values in gold silver and copper.
 The Octave mine has been under going repairs and carrying on a sys- tematic line of development work In the past. the Octave has produced a very large amount of gold bullion, and as its ore reserves can hardly be said to be more than touched, 1t may be looked for in the near future to re- sume it's old time activity as a pro duceT of the yellow metal
 The Antelope Gold company is at present reconstructing the pipe line on the Yarnell mine. Large bodies of ore are known 10 exist in this mine and when the proper repairs are com plete this property will again come to the front as producer of bullion.
