and ninety (l90) feet, at which point it intersectcd the Buckeye fault, where the tunnel was turned, and drifting west along the course of the vein has now progressed three hundred seventy seven and fve-tenths feet (377.5) feet, with most gratifying results. At the point where the vein was cross-cut it was found to be twenty seven (27) feet wide, with well defined foot and hanging walls, and as far as developed on our ground it has proven to be thor, oughly mineralized. On July 10th commercial ore was encountered in the drift, and continued for a distance of one hundred and seventy-fve (l75\ feet, with occasional punches of ore in evidence, as drifting has progressed A stope one hundred (100) feet in length has been timbered, and every thing is in readiness to begin mining
 samples taken from day to day have the ore at this point. Assays from
 varied between four per cent and if
 teen per cent copper, in association with from sixty per cent to seventy per cent iron oxide, and carrying not to exceed thirty per cent silica thus mak ing the ore desirable smelting ore The vein outcrops on the apex of the Black Oxide hill four hundred eighty
 (4S0) feet above the roof of the tun- nel level, where, by means of trenches and open cuts, it is found to be sim ilarly we'll mineralized and well charged with copper contents; so that, at and above our tunnel level we already have
 something real and tangible in the shape of an ore reserve. On this same vein, at a distance of only fifty (50) feet from the end line of our Ida claim, the Buckeye shaft of the Old Dominion has attained depth of about three hundred and fifty (350) feet. and is still in the oxidized zone. The opinion of mining men experienced in the dis trict is. that this shaft, or drifts there from, will encounter sulphide ore with
 in the next three hundred (3O0) feet The proximity of this work to Superior and Boston territory, and the results accomplished by it, will serve to de. termine for our company, in advance the character and value of this vein at lower levels. On the True Blue claim. owned by the Old Dominion, which i'm. mediatcly adpoins our Black Oxide claim, and about fifty (50) feet from our line, prospeetors operating under lease, have sunk shaft one hundred (lOO) feet deep, and have taken out very good grade of ore. Reference to operations on the lands owned by adjoining companies is made, as evi- dencing the persistency of the veins which traverse Superior and Boston ter. ritory, and the occurrences of ore there in.
 single compartment vertical shaft has been sunk to a depth of three hun. dred and forty (340) feet on the Lime. stone claim, stations cut, and five hun. dred and seventeen GID feet of cross. cuts and levels opened. The vein was first encountered in the shaft at a depth of about seventy (70) feet, and was less than two t2l feet wide, but was well charged with copper, averaging about seven per cent. Conforming to the l characteristics of other veins in this 1 district, it has continued to widen with | depth, and at the second level two hun. | dred and twenty (22O) feet down, il has varying width of from three (3) | to seven @ feet. Very little work was done at the first level, the desire being to determine what might be ex. pected of this vein with depth, and it is safe to say that the showing made at | the second level has exceeded out ex. pectations On this level good ore was encountered in the vein, distance of | thirty-five (35) feet from the shaft | where it was cross-eut, and the drift | has been extended one hundred and for. ty-two (l42) feet in ore, which will average six per cent copper, carrying an excess of iron, as is the case of the Black Oxide ores.
 Drifting at the third level is now in progress, and the results accomplished will determine whether it will be ad. visable to sink the present shaft deep CT, or tap this vein at greater depth by cross-cuts from tbe proposed three. shaft to be sunk on the Red Oxide claim, to open the Iron King, Black Oxide, and other veins
