tMrltteE in cananea, by Geo. l.. Walker, of the Boston CommercialJ
 Greene-Cananea is developing into a low cost producer of copper. The statement of Dr. l.. D. Rieketts, gen eral manager, in the annual report. that if the average yield can be raised to 50 pounds of copper per ton of ore the cost after June. this year, will be nine cents or less. will be fully verified. The actual cost last year was only about 963 cents; but this was raised 10 1l.51 cents by including s6S4.000 of construction and better ments, 1.S5 cents per pound of cop per, as a direct operating cost.
 At present the company is produc- ing its copper for well under nine cents a pound. Its construction and reconstruction work Is completed, aft CT the expenditure of nearly S4,000,oe0 practically all from operating profits. It is now producing between 4S,00e,0o and 50, 00o. GOO pounds of copper, and when curtailment is no longer neces- sary its output can be increased to 65.000.0o0 pounds annually with it's present equipment.
 Dividends Expected Soon.
 ne I4ldU1EtUICMl Ao dAA4LAAAAAo N0 get the company in position to re- sume dividends, and there is no doubt of it's ability to accomplish this in the coming year or two. Producing 50,0o0, 900 pounds of copper at a cost Of nine cents, Greene-Cananea must now be earning 20 cents share on its outstanding 2,500 shares of stock. With an output of 65,000.000 pounds annually and a 15-cent copper market the company will be able to show earn ings of s1.e0 a share.
 The company's equipment has been thoroughly reconstructed and re- newed. and is doing very economical and effective work. Most decided inn proyements have been made in every department of it's operations. The very great expense of these improve ments was due to the fact that the whole plant with the exception of one concentrator, and the ore bedding shipment. was in extremely bad con dition when the present management came into control Even the ground under the engines in the power plant had to be excavated and new founda- tions built. All of the eight furnaces in the shelter and one reyerberatory are new.
 Simpler System.
 The system of handling the ore, from the mines to the plant, has been simplined, the smelting ore mixture improved, fiue dust and concentrating losses decreased, power costsN greatly reduced and the conduct of every de- partment put upon a systematic bas- is
 Among the most important works ae- complished by the present manage ment is that of extensive mine devel- opment. More than 10 miles of new openings were made last year and the work is still going forward at the same rate. The company has at least f1ve and nerhans ten years snnnlv of ore in sight: but tonnage figures are never given out by the management.
 Development has now advanced suf- fieiently far to make possible an in telligent statement as to the character of the Cananea ore deposits Begin ming at the east end and going west, Greene-Cananea's mines occupy the following positions, Cananea Duluth, America, Cobre. Grande, Kirke, Veta Grande, Oversight. Capote. Indiana Sonora, Elisa, Henrietta and Puerte- citos. These mines make up an al most continuously mineralized area approximately six miles long
 Broadly considered the mines are of only two classes, porphyries and re- placements in the limestones. All of the mines, with the exception of the Kirke, Elisa and Puertecitos. are typ ical porphyries, blanket, secondary en- riehment, deposits of concentrating ore, though it is better to smelt some of the material than to mill it. The kfrke is small limestone mine oi good grade, the Puerteeitos one oi very low grade, and the Elisa a great big rich mine.
 Combination Tunnel
 Included in the Elisa workings is a considerable portion of the Indiana Sonora ground formerly owned by Phelps, Dodge & Go. The Greene Cananea management arranged. two years ago, to run the Combination tunnel half mile through Indiana Sonora ground, the expense to be borne equally and the tunnel to be used jointly with Phelps. Dodge & Co. This was done; but before the workings penetrated the Elisa, Greene Cananea purchased the Indiana So nora ground.
 In this portion of the Cananea's 's mineral zone there is very large limestone area. about two miles long and half mile wide The Elisa work ings had opened some very good ore in this and a little had been devel oped by Phelps, Dodge & Co. During the past IS months this area has beer opened very extensively and with splendid results.
 The Elisa deposit is in many re spects similar to that of the Granby except that it is much higher grade This ore averages about 3-4 per cent copper, three ounces of silver and 8; cents in gold to the ton. Apparent ly it will make a big mine. The cop per occurs as ehalcopyrite, accompan fed by iron, making it valuable as g fiux for silicioas ores.
 Of its porphyry mines the largest and best is the Oversight. This de posit is about 5000 feet long, from 50 to 530 feet wide and probably 200 to 300 feet thick It averages 2.5 tc 3 per cent copper, and some of ths ,r< fo an rich that fl oooe directly fr
