 Bureau Gives Interesting Facts.

The Boston News Bureau has re
 ceived the following report on the
 Greene-Cananea property from .

 Cananea and who is in a position tC I learn the "inside facts"
 The company is overhauling its ma
 chinery plants, completing the
 changes in its shelter, revising its
 concentration scheme, renewing ma,
 teria1 and evidently arranging to
 make copper cheaper and on a larger
 scale when operations are resumed.
 The cost of copper during the past few months has been exceptionally
 high, but, contrary to former prac-
 tice, all costs of reconstruction, etc.,
 have been put into current costs. This period has witnessed the com plete rehabilitation and reconstruc- tion of the smelting works, every one of the former furnaces, except Nos. 2 and 8, having been torn out and re- built larger and uniformly, before the shutdown, and these two have been nearly completed since then. Formerly the furnaces were of various sizes, poorly arranged, crowd ed, and several of them were still of the Mitchell hot blast type, an un- suitable installation, put i'll by Geo. Mitchell, when manager, some years ago.
 In connection with cost at the Greene it must be remembered that metal sayings from the concentrators have never averaged better than 72 to 75 per cent. of the assay values of the concentrating ore, varying with the amount of aluminiferous material in the gangue. The great tailings dam, therefore, carries probably bet ter than 1.20 per cent. copper, a tre- mendous loss. Also that the metal savings in the smelting and Bessemer processes returned a saving of about 90 to 92 per cent. of the mineral, as near as could be ascertained from the that was possible, close being difficult from the fact that there was hever, until quite re- gently, any chance for mixing and storing. In other words. an ore run ming per cent. copper would go to the shelter as 2.25 per cent, there to be mixed with one-half it's weight of an ore running, say, per cent, giv- ing a mixture worth, gross, 63.2 pounds copper to the ton. This when smelted, showed reduction to about 4.88 pounds to the ton, or, at 12-cent copper, value per ton of S6.82, aside from any gold or silver.
 There is no mechanical, metallurgi- cal or economic reason why Greene should not produce its ore for that price, but it may be doubted if it has yet done so.
 The concentrating ores of the Can- and Cananea Central, now parts of the Greene, carry no souch high aluminium content at the Oversight, from which nearly all the low concentrating ore has been mined in the past; therefore the use of low grades from either of these properties should increase say lngs. Those properties probably con- tain enormous low grade deposits with some precious metal values. Despite what may be said by uniform ed individuals, the Cananea-Duluth and Cananea Central are perhaps the AE Aa possesses. The former can be made to show a vast tonnage of ore excellent for concentration and carrying several ounces of silver to the ton.
 The Elenita Development company. owning the Bonanza de Cobre proper ties lying alongside of the old Greene has called $3 payment on its stock and is at work. It is capitalized for 20, 900 shares, par SlO. of which 6,OOO| are in the hands Of Lindsay and Tal- bot, original locators, the same amount in the hands of L. w. Powell for himself and many associates, and the remainder held by Messrs. T. F. Cole, c. A. Congdon and associates in Duluth and the east. The property is looked on as ot excellent promise and will be developed at once.
 At present the Calumet & Sonora is the most active mine in Cananea, and it is operating at Catalina group, Bonanza de Cobre and the Greene mills. It is making shipments of silver-lead ore. running to about $50 a ton in value, to the Luna smelter at Deming. One or two cars of this ore will be shipped in the course of a month or so.
 The government of Sonora has ap- proved the action of the big company in shutting down its works, and has remitted 50 per cent. of the state taxes to all merchants in Cananea and surroundings, indefinitely.
 It is said that l4,00O persons, men, women and children, have left Can anea and district in the past forty days.
