Show RIO GRANDE SHAFT CUTS FOURTH VEIN Entire Bottom in Ore That Resembles Sulphide of Silver. The entire bottom of the two-compartment shaft on the Rio Grande Grubstake property, located twenty-five miles east of Mason Valley. Nev.. has broken into sulphide ore at a depth of 305 feet from the surface, according to a letter received bv the local officials from Managing Director Di-rector W. P. fHiilth. The letter states that the .hl. kness or extent of the bouj hud not been determined when the ct-ter ct-ter was written, but that the shaft had penetrated the ore for a distance of three feet The ore resembles sulphide ot silver sil-ver and samples have bean sent to Reno for assay. , , The shaft has been passing through a heavily mineralized formation for twenty-five twenty-five r'eet above the 300-foot point and just prior to the strike the hard granite was left and a soft blue limestone was encountered which carries quarts and is heavily mineralized. Four veins have been cut in the shaft. One nt the eighty-two-foot point was eight feet In thickness. One at the 2-.i-ro'ot point was twelve feet In thickness and one at the 267-foot point was seven feet In thickness, but neither the extent nor thickness of the last one has been determined. Inasmuch as the veins carry values, the management has decided to prospect them and a station has been cut on the 300-foot level, from which point cross-cutting cross-cutting and drifting will be started as well as raising on the various veins. The principal values showing on the surface in the various veins cut have been In copper, though there is also some gold and silver values. The property has been thoroughly equipped with a compressor and oil engine and the necessary power drills and hoisting machinery. A campaign cam-paign of development work has been outlined out-lined that is being pushed ahead as rapidly rapid-ly as possible. |
