TWIN PEAKS CO. NEW FACILITIES
 MEAN MUCH IN ENCOURAGEMENT

Of tremendous importance 10 all the gold mining interests of this sec ton Of Arizona and New Mexico is the purchase al Fl Paso this week. by the Twin Peaks Mining and Milling company, and it's installation within few weeks at the site of the mines of a cyanide nill of large capacity, says the Clifton Copper Era For years the interests of the mining world has been directed 10 the gold bearing ores of the Twin Peaks sec tion. as these are large bodies of ore that are of percentage that would seem to promise untold production. should the proper methods of econom- fcal concentration be solved. In this section are the famous Carlye mines, the Apache Box mines. and number less claims that are of the same geo logical formation. and all carrying gold imprsgnated ores. At various times rich veins have been developed. with great profit, notably that era of successful operation that some twen- ty yeara since came to the Carlyle properties when millions of gold was produced, but crude methods of re- duction have resulted in discontinu- Rnce of operations.
 Only recently a min employing methods of analgsmation was in stalled at Twin Peaks. and with this mill ore has been treated at a hand some profit. but is learned that much of the gold. about oue-half of the con tents of the ores. was not secured. the causing thiH portion to escaDe with the haser composition. and this per ccntage of waste determined the nRnaserent of the mines uDon the installation of cyanide plant that would properly reduce the ores. as 1t was apparent that the ores treated at the amalGsmation mill would of neo- eassitv fin later years ha treated Q spoond time. thus rausinV unnacea- sarv expense. It was decided that cyanide Dlont would be the meet ar- ceptahle method of economical anl complete reduction. and accordinolv Nessrs. Fraser.

This is ? method of concentration at present employed. as if is estimated that nearly one-halt of or about ten doIlore of gold, is left intact in the treated ores.
 The opinion of mining men well aeuusinted with these and surround. ing properties is that this installation of modern cyanide plant is all that is necessary for a camnaign of de. velopment that will at last realize the
 most optimistic hopes of it's discov. erers and stockholders. after wears oi pstnent development and efforts to by all conversant with Twin Peabs that enormous bodies of ore can be finally bring Twin Peaks to a stage n' profitable production. It is admitted secured there, and that all that was lacking was a reduction method of sufficient economy to make the net result of profit
 The mill will be used in connec. tion with the mill at present in serv- ice. The crushing machinery, con. centrating plant, and power plant will be retained. The shines in the con centrates demanded that a method
 of cyanidation be employed. as muc
