eoNcENTRATOR AT MORENcI TO
 HAVE CAPACITY DOUBLED.
Arizona ooper Company Adds New Conserter-Makes a Record Break CT For the Carnp-Larger Amount of Home Capital Going Into the De velopment Of Properties.

shut-down of the D. c. concentrator spon installation of the last of the new equipment for doubling the capa- <Ity of the plant Superintendent Hunt stated this week that it would probably be six months before oc- <asion arose for such action, if then. il is possible that the new machinery can be added without interfering with the operation of the cid plant.
 The A.-C. company recently added q new converter to their plant, mak- Sng three in all, which greatly in- ereases the output of copper. For some time past 1t has been averaging from 75 to 50 tons per day of copper, which is mere than 99 per cent, fine, and is said 10 be the finest quality of copper made in America. This month she A. c. will output more than 2,OOO cons of copper, which is a record breaker for the plant. and is perhaps the equal of any plant outside of Montana
 Clifton sets a splendid example for the camp in the matter of investment sn and encouragement of the nl'n'ng industry in the home field. In the East few months the business and min fng men of the town have pu- s.oi -nany thousand dollars into the devel- epment Of home proper.iAs. That Gheir faith in the district i5 justified none can find good ground to dispute. That they have put their money up along with their confidence is a fact Sorth dollars and cents 10 every prop erty in the camp. No better evi- dence could be summoned of our faith fn our own. Capital asks no better recommendation of property than Nome investment in it.
 General manager James Colquhoun, of theArizona Copper company, gives in the annual report of the governor cf Arizona to the department of the properties, production and operation CT the proper lies, production and 'op- eration of the reduction works of his company in this camp.
 The mines of this company are Known throughout the mining wOrle and are among the richest and most profitable copper producing proper ties in the United States. The growth of the mines being presented in ad ditiOnal equipment and the spreading cut Of the camp borders.
 The mines of the Arizona Copper 1ompany are situated in the Copper mountain and Greenlee mining dis syicts, near the town of Clifton.
 Tn the earlier years only oxidized iIes were treated. these being founc sn contact with the limestoneS which flank the mineral belt.
 Later. as the oxide belt was becom- ing exhausted, the adjacent porphy-y vas prospected, and this, especially on its contact with lime shale, very large veins of sulphide ores were le- seloped
 These have been developed to depth not exceeding 800 feet, and for a length of nearly 1,500 feet in the strike of the veins. The veins are aice and very continuous, frequently exceeding 100 feet in width.
 The ore is very low-grade sul- pnluc ore. SO per CSHt Ol Hu4Nu -o concentrating material.
 The reserves in sight above the 50O-foot level are sufficient to insure One company of many years of active existence. About 70 per cent of the output of the company is obtained from this source.
 The Metcalf group, distant seven miles from Clifton, is largely worked by the open-cut system. The prin- cipal ore is an oxidized ore occurring fn porphyry. From this ore the metal is extracted mainly by the Teaching process
 About 40 per cent of the output of tue company is obtained from Me-- calf. The ore is lean. but it is ob- fained in abundance and can he c1eapiy mined.
 The Coronado group, distant nine miles from Clifton. is in process of development. The work done during the past year has greatly improved the prospects of this property, which uill soon become a producer.
 The metallurgical works are situ- ated at Clifton. and they are connect e1 with the mines by three-foot gauge railroad. which Is admirably equipped for heavy work.
 The smelling plant consists of six water jacketed furnaces, each of 300- fons capacity. The Bessemer plant Is euuipped with seven-ton converters, zn electric crane and many up-to-date appliances. The plant has a capaci- ty equal to the Bessemerizing of 20,- on0 tons of copper per annum. The concentrating plants number four in sn. They have a gross capacity of Tsn0 tons per day. The teaching slant treats 25o tons per day. It is
