but all of a grade lower than per cent. is left on the dump and reverts to the company. Several hundred men are employed by the lessees, and 1t IS said by those in position to know that the company has been making big money by this arrangement. In all about 1900 people are in the Santa Rita camp. The property is under the charge of B. B. Thayer, as manager. Mr. Thayer has had much experience a. manager of large properties, and Is most highly spoken of by all who have business with his com pany.
 THE CLIFTON COPPER co.
 of which a large amount of stock is held in Clifton. has ten claims adjoin- ing the patented property of the Santa Rita Co. on the west. This property was purchased from the original own CTS last fail, and work at once com menced by the new company. The old shaft has reached d depth of l60 feet, at the bottom of which a drift has been uu -Vp lCCN. all III OiN- -AAi oi ShS Der workings are in ore. 4 new double compartment working shaft is now be- ing put down. and has reached a depth of 130 feet, the last 30 feet being in ore. It was expected that ore would be reached atl15 feet, but it was struck at 100 feet. which was most agreeable surprise to the management. The ore when first struck in the main shaft had been leached, but its value is grad fly increasing as depth is attained, and is now being milled. When the ERA representative visited the property, nearly two weeks ago, he found the mill just starting up. The mill is ar ranged for four concentrating tables, with daily capacity of D tons each, but at that time only two NewStandard concentrators were running. twill be remembered by readers of the ERA that the tops of the other two tables were washed away in a flood several weeks ago, and although every effort i had been made by the management to secure them, they had not been re- placed at that time, but were on the way, and are now doubtless in opera tion. The mill is arranged for econom- | ical handling of the ores. The ore is mine, conveyed 70 feet to the mill in cars. dumped over grizzleys and into the ore crushers, thence through rolls and on into two Huntington mills, from whence it is conveyed in pulp to the concentrating tables. The values of the ore are in the form of sulphides, and the ore itself is so soft that it is l thought the two Huntingtons will be able to supply six concentrating tables, with capacity Of about 150 tons daily. ! Floor room has been left for another Huntington, which will be put in place | in a short time. The new steam hoist 1 ing rig is good for depth of 700 feet. It derives its power from its own en- zine and boiler. The motive power for the plant is supplied from an SO-horse- power engine and 120-horsepower boilers, which is ample to largely in- crease the mill capacity. The water is conveyed through a pipe line a guar; 1 ter UT mile to 50,00O-gallOn steel tank located on hill above the hoist ing plant. The water supply is ample. l The mill itself is we'll constructed, and although as stated, had just been start ed up, was working we'll and produc- ing p per cent concentrate. A dynamo and electric light plant is on the ground, and the plant and mine will soon be lighted with electricity, without extra cost. Good wood deliv- cred at the mine costs & per cord, but the management expects to reduce that somewhat in the future. The concen- trates are hauled over first-class wagon road distance of a quarter of mile to the railroad, for D cents per ton, and from the station to the shelter at Silver City for S1. p per ton The ERA was not informed as to tie per cent of copper the ore carries.
 THE IvANHOE
 located originally by J. P. Risque, who was killed by Indians in Gold Gulch, near Morenci, in the spring of 'S2, is one of the oldtime producing mines of the camp, and is still owned by the Risque estate. It is now being work ed under bond and lease by J. w. Bible. who has asslsted materially in the up-building of the district. A shelter was erected on the mine in the sos by John R. Magruder, and the property worked for time, but the ore contained so much zinc that it could not be worked at a profit. Mir. Bible, however, has gone through the zinc belt, and now has large bodies of ore carrying copper, silver and lead. A steam hoisting plant has just been placed on the property which is now out-putting about 10 cars of ore per month, which will be largely increased in the near future. The development of the Ivanhoe under Mr. Bibles man. agement is considered of much im- portance to the district, as it has demonstrated the fact that good ore exists under the zinc capping, which covers many Of the mines of the dis trict.
 THE SAN JOSE.
 another of the most promising mines Of the district, was also located by J.
