Show activity act I 1 v ity at liming lun ing nevada BY AL ai H MARTIN luning liming nev oct 8 the past year has witnessed the rapid advance of the luning liming district to the position of second most important copper field of nevada more than a dozen properties have become producing mines and a number of others are on the eve of becoming profitable shippers high copper prices have naturally stimulated development and many deposits known for years are now for the first time undergoing comprehensive exploration unlike most other districts luning has never been widely exploited in the press and the operators have shown a disposition to discourage anything savoring of a boom preferring to establish the merits of the field by substantial and conservative development work principally copper ore of the district ranges from 2 to over 21 per cent copper with some of the mines showing considerable silver and some gold on the lavada calavaza Ca group formerly known as the giroux the ore zone has been opened to a depth of 1000 feet and a deposit of red oxide and gray copper ore was recently intersected at this depth about feet from the shaft some of this ore averages better than 30 per der cent copper from the wall street and st patrick properties considerable high grade ore has been shipped and on the luning idaho rich ledges running high in silver have been opened in conjunction with the main copper bearing veins on the property of the R B T mining company adjoining the luning idaho gold silver shipping ore has been opened at several points many other properties show silver and gold but in most cases copper predominates largely pilot copper building mill the chief factor hitherto militating against luning developments has been lack of adequate reduction facilities this is now being overcome by the construction of a ton leaching plant by the pilot copper company known formerly as the nevada champion and the assurance that the second furnace of the mason valley smelter at thompson will be blown in within forty days and will operate largely on luning ores the pilot copper people plan to eventually increase capacity of their plant to 1000 tons daily and other companies intend to install reduction plants as soon as conditions justify in this way the principal obstacle to heavy production is being eliminated luning idaho development the luning idaho Coni company pany owning one of the largest and most thoroughly developed groups in the field h has as completed arrangements range ments for heavy shipments to the thompson smelter drawing the earlier ship ments from the mcdavitt shaft and conte sections of the mine large areas of productive territory have been opened by the hahn erickson bradley and other tunnels and comprehensive developments have been carried out in the form of open cuts crosscuts cross cuts and numerous laterals literals late rals sufficient oxidized ore is already exposed to insure years of profitable production and latt late developments in the sulphide zone have been even more encouraging recently a deposit carrying exceedingly high values in silver was uncovered on the sophie claim and a tunnel is advancing to open this vein to depth A site has been selected for a main working shaft and work on this outlet is about to start R B T ready to ship after years of persistent effort the R B T gold silver group is ready for a heavy output and will start shipments within thirty days connections have been made between the edith shaft and meyer tunnel facilitating handling of all the ore through the tunnel ore bins at its mouth will load directly into the shipping cars the older workings of this mine contain an immense tonnage of silver ore formerly too low grade to profitably produce but now forming a high grade shipping product the edith shaft has been sunk on the ledge carrying important gold values and much of the richer ore will be sent out from this the newly opened section of the property the district is connected with well built roads with the town of luning on the ha zen goldfield branch of the southern pacific and climatic conditions are ideal for all year activity most of the mines have been well equipped and are controlled by strong ly financed companies new york nevada and utah people are principally interested |
