Show rapid drapl d development of rochester nevada BY FRED ay iy MINER rochester nev april 6 mining affairs are moving along rapidly throughout this district and students of the situation are

applied to the chloride ores cyanide will probably be used in the treatment of some of the ore the mill will be located in american canyon on the east slope of nenzel hill feet from the portal of the present working tunnel on that side and feet below that level mine and mill to be connected by surface tram it is estimated that there is now practically in sight and of splendid milling ore but the ore may soon depart on its dip away from the more vertical course of the will list rochester united officials of the rochester united mines company are preparing to list that stock on the san francisco stock exchange not later than april and it is expected to become one of the very active traders because of its favorable developments and location between the rochester mines and rochester merger on the north and rochester combined on the south development work is being pushed in two tunnels three feet of ore that shows good bannings pann ings in big four lease mines rochester mines mined company is now almost ready for operation and will soon he be delivering ore to the full capacity of 0 the mill which is between and tons per day the new on the foot level is spreading in proven dimensions ranging froni from twelve to twenty feet between walls developments in other portions of the mine mille are holding up to their normal splendid showing rochester combined co mines L A friedman announces that p preliminaries are going ahead rapidly for early construction st ruction on the first ton toll unit of the proposed ton mill of the rochester com bained the equipment will consist of a big gyratory crusher from which the ore will pass to ball mills loaded with pounds of steel balls ranging down from five inches in diameter to about two inches tube mills will regrind the ore and it will ultimately pass to cyanide tanks thirty feet wide and thirty eight feet high the solutions will then pass through filters and the precipitates be turned into bullion mr states that he plans to install electric automatic machinery wherever possible to cut down mining and operating costs to a minimum the mucking in the mines will be handled automatically as far as possible and when development has advanced sufficiently to justify electric tram cars will be operated in the mines and deliver the ore to the mill u 1111 the entire equipment will be along the most modern lines available the new horsepower compressors pres sors have been ordered underground developments continue of a most favorable character the in the shepherd tunnel having been opened by crosscut for feet and drifts are stood to have averaged about 75 per ton crosscutting east and west is in progress from the tunnel on the houle home trail veins that are tile the to open the vein or source of the high grade float ore that has been found on oil this property which indicates the close proximity of a large body of good ore the veins known as the east and west veins are being sought at depth writer visits rochester combined because of the great public interest that is being manifested in reports of operations of the rochester combined mines company headed by L A friedman president of the rochester mines company I 1 have made a thorough investigation of the property since writing the above and have found the showing of ore to be one of the greatest in milling illing propositions it has ever been my pleasure to examine accompanied by superintendent wilkie and J C bray mining engineer of tile the company I 1 went through the workings and was by them given the figures I 1 shall use as to the values that have been developed pose of blocking out and proving up the ore more definitely a crosscut is soon to be driven from this drift about feet south of the present crosscut that has hag failed to develop a during its progress of feet 1 ore in main tunnel e l this ore has now been encountered in ill the main working tunnel which was driven nearly feet in less than one month and the values are about the same as on the hanging wall in the shepherd no 1 L tunnel at this place a large iron blacksmith ishop has been erected and a sullivan drill sharpener installed it is 18 planned to connect this tunnel with the shepherd no 1 workings by a series of raises and the ore will be brought to the surface here and conveyed to the mill by electric haulage in trains of mine cars the mill construction on the first ton unit of which will soon be commenced will be located on oil the sunny slope of a hill opposite tile the mouth of the working tunnel and a track will be driven along the

surveys started for the site of that companas comp anys proposed mill on oil the american canyon slope of nenzel hill mr nenzel states that work on the first unit of tons capacity I 1 will be commenced early in may and pushed 0 to completion as rapidly as possible the raise from the pitts nenzel tannei to connect with the main crown point 41 workings is now up over feet the fe on the zero vein is going down rapidly and it is believed that the connection which will be feet will be completed by may the zero vein was recently crosscut in the crown point workings in preparing to sink the and reveals thirty four feet of pay ore when the connection with the pitt nen zel tunnel is made an air pipe line will be K strung through it from the crown point ii compressor and the tunnel will be contin ii libed aed ahead through nenzel hill it is the lealan of the company to install an electric ry haulage system in this tunnel because of s the long haul required in this tunnel is now in over 1800 feet and will be nearly double that length when completed e the property is looking very good in a genii eral way and has large showings of ore le ie more about the rochester mines 16 11 over thirty feet of high grade ore much t of which shows native silver has been a 1 opened in a crosscut on the foot level A of the rochester mines company adjacent 11 to the codd or the discovery was made by crosscutting toward the hangi 4 ing in wall of the east vein to connect with P a vertical raise that is to be put up from the foot level to drop ore through for ay iy transportation to surface by way of the is 19 friedman tunnel the size and value of is this ore was a surprise to the management s e as it was not anticipated when vl ien this work was commenced the hanging wall has not yet been reached so its full extent has not been determined some fine are being opened at other points on this level as well as on the and levels that have been driven out from the the ore ranges from eight to fourteen feet in width and is maintaining a good average grade in gold and silver rew new find of ope in cutting into the in various places where ore had already been mined a new layer of ore carrying better values in gold than had heretofore been known has been opened and its extraction will in instances make it necessary to mine this ground again an interesting discovery has been made in the old four J block on the foot level where it has been ascertained that the leasers leaders worked only a small portion of the ore recent development exposing ore across a width of twenty feet this will be worked as a filled the ore being drawn off at the transportation tunnel level and mining conducted on top of the broken ore in the the north drift on the foot level is being pushed ahead in ore and other portions of the property are making a fine showing the new two mile aerial tramway has been completed from the friedman tunnel to the mill and the conveyor equipment and crusher are now being hi installed stalled at the head of the tramway with the capacity of the mill raised to approximately tons per day and the tramway in operation and delivering an uninterrupted supply of ore the output and earnings of the company will be greatly increased almost immediately |
