Show THE centennial EUREKA in speaking of the centennial eureka mine at eureka utah a correspondent of the new york news new letter says one of the most interesting tasks ever undertaken in mining is that soon to be tried out by the centennial eureka company the control of which is held by the united states smelting smelling Sm elting refining mining alining company this mine has produced many million dollars worth of silver lead gold ores and there are several million dollars still in ore now blocked out all this has been brought to light in the oxidized zone the management is now preparing to explore below the water level and the oxidized zone into the sulphide zone to make this possible two swiss pumps are being installed each with a capacity of gallons at a depth of 2100 feet from the collar of tha the shaft the centennial eureka has struck the water level level apex adjoining has the same conditions at the 2200 level while the gemini has the same at the 1600 level considering the difference in elevation oe 0 the three shaft collars the three have identically the same water conditions at the same vertical depth and this satisfies the management that the water level has been reached at last the fact that the company is going to such an expense for the purpose of developing the centennial eureka at deeper levels is considered proof enough of the confidence the officers repose in the mine the I holden tunnel has been driven to meet this new pump installation the tunnel driving a much more economical avenue into the mine for ingoing supplies while the fact of its connecting with the level of the shaft does away with the necessity of hoisting the ore and pumping the water a distance of feet to the surface the tunnel connects with the railroad tracks thus saving a haul of several miles arlund the mountain to gain the greater altitude |
