Show TH THE E OSBORNE LOOKING WE WELL LL statesman boise idaho developments of very great importance have been obtained from recent cevelo development p work by the idaho mines development company on the osborne group a at t horseshoe bend in the pearl mining dis brict three veins that merge into one exceedingly cee strong lode have been opened up at numerous places proving the continuity of a mineral bearing zone the full length of three claims feet A number of assays essays have been lately taken from different points at depths of from grass roots to feet returning values ranging from to in gold and silver the general average is 1876 in gold and 2010 in silver the ore is of the same general character a heavy quartz sulphide carrying iron and lead in addition to the two precious metals one of the important features in connection with the development of the property is the fact that values materially increase with depth another fact of great importance is that the width of the ledges increases as depth is attained the ledge in the bottom of the foot shaft showing wider than the shaft while the outcrop ping east of the junction of the three veins indicates a width of from thirty to fifty feet in five assays essays taken last week the one from the foot level returned gold and silver at this point there is eight elicit feet of ore showing without either wall being disclosed this is the main working working shaft an incline that will be continued to a depth of feet from which point crosscuts cross cuts will be run to open up the parallel Piral lel leads the north vein has been opened up by a shaft to a depth of only eighteen feet at grass roots the values were around 10 per ton in the bottom of the shaft there lids has been disclosed a streak of ore a foot wide along the foot wall from which as says of have been obtained the ledge has widened out from a narrow seam to fully three feet the remainder of the vein is good milling ore A crosscut tunnel ts is being run from the bottom of the incline that will cut this lead at a depth of feet there remains about forty feet of crosscutting to reach the ledge A grab sample taken from the dump of the eldorado claim with a view to determining the average value of the ore extracted thus far in development work returned values of 2298 the lowest sample taken was from a point 1500 feet east of the incline the return being this assay was from grass roots A sample taken from the same ledge at a depth of fifteen feet showed a value of 2444 A complete new plant of machinery has been installed including a hoist capable of a 1000 foot lift gift and a large pump that will ha handle n idi ail afi of bf the water ater the mine Is now taking development work is being vigorously prosecuted with view to extensively opening up the mine during the year a reduction plant with a daily capacity of 0 fifty tons will be installed when this I 1 ig done the mine will become a regular pro ducer that will materially add to the output of 0 the district in speaking of the osborne manager richardson said he is sanguine it will develop into one of the greatest mines in this section prominent mining men who have been identified with the development of the largest properties in pearl have recently visited the property he stated and have pronounced the showing the best thus far made in that locality with the opening up of the north vein beyond the junction an ore reserve will have been established that will insure regular shipments for several years |
