Show BIG PORPHYRIES COJNC CFLENOIBLY. Colonel D. C Jackllng, general manager man-ager of Utah Copper, Kay Consolidated Consolidat-ed and Chlno Copper, returned yesterday yester-day from a regular Inspection of the big southern porphyries The Ray mill is now treating an average ot nearly 4,000 tons of ore dally By August Au-gust It Is expected to Increase llils fully 1,000 tons, and continue until the mammoth plant has reached Its ultimate ulti-mate capacity. The colonel says the grade of ore has come up a little better bet-ter lately, and as depth Is Increased ll should soon average two per cent, The recoveries are now averaging around Ecventy-ono per cent, which 16 considered very, satisfactory with the present grade of ores. A small tonnage Is now coming from the newly new-ly acquired Ray Centro-l territory. The expectation is to bring the other three sections of tho mill Into requisition as required to handle the output from the mine. At Chlno, Mr. Jackllng says that the production will be up to 2,000 tons dally before the first of July, this being be-ing the amount of the mill. The fourth , section will be ready tho forepart of i July.jvhlle the fifth .vM be ready in i August. Thon the total tonnage under treatment will acrage around 5,000 tons a day. It is found that as depth is reached on the ores, and the values increase, that the rate of recovery a the mill gradually Increases also. The stripping Is keeping well ahead of the extraction, and the heavilj oxidized ores are giving place to the better GradeH shaping up at greater depth The colonel says that conditions at the Ray Consolidated are continuing as satlsfactoiy as ever. As a result of recent extensive development work the grade of ore is running a little lower but the tonnage Is heavy. The stripping strip-ping of new territory Is advancing rapidly. About July 3 Colonel Jackling expects ex-pects to go to Montana to make an Inspection of tho Butte and Superior, where the mill Is reported to bo making mak-ing a saving ot better than 1)0 per ceul. The 110.000 volt transmission lino that was recently put Into operation In tho fltntc of Michigan markH another anoth-er step forward In the utilization 'of high voltngc Tor the transmission of electric energy. In transmitting at 140,000 volts, the. builders have effected ef-fected a saving in copper of almost 50 per cent, as com pn red with tho quantities used In the hlgheBt voltage lines previously vonstructed. i |
