Bisbee daily review., 1917-11-04

tered carry disseminated pyrlte, ana solid punches of both pyri.e and mag netite have been found. In a number of places, both in the northwest workings and near the Columbia shaft, traces of copper have been found in both oxidized and sulphide form, but the only place in which commercial ore is now exposed is in the raise from the 300 level in the southern end of your Maintop claim. The exposure at the foot of this raise is about 20 feet in length and II feet in width and averages to 10 per cent copper. This raise has been driven upward 5S feet during the last two weeks, and the face now shows per cent copper ore g feet wide. About 40 tons of ore of similar grade have been shipped to smelter, but settlement assays have not yet been received on these ship ments. Work is being continued in this raise and additional shipments are anticipated, but exposures are not yet sufficient to estimate any definite quan- ti.y of ore ahead of production.
 Diamond Drill.
 During last April 13 inches of rich copper ore in the form of core was produced by the diamond drill runners and reported by them to your superin- tendent as coming from two feet of the hole then being drilled. It. was i'm mediately ascertained that these drill runners had delayed their report to your superintendent until after inform ing others in Jerome, and they were discharged at once. A crosscut, sub sequently driven to the place where the ore was reported, showed the com plete absence of ore. It is evident, therefore, tha. the drill runners not only dishonesty delayed their report, but misrepresented the facts.
 During the past year the Columbia
 shaft has been equipped suitably for hoisting and pumping from the HOO level and a compressor of 900 cubic feet capacity which was installed when operations were resumed on the prop cry early in 1916.
 Development work during the com ing year should progress more rapidly than during the past year. After the Columbia shaft reached the depth plan ned, about April 1st. considerable time was consumed in the installation of permanent shaft equipment and in the preparation of the HOO station with pumping equipment. Subsequently, until the middle of July. there were but two working faces from the Co lumbia shaft. therefore there has been opportunity for but a few months drift ing and crosscutting at capacity in he Columbia shaft workings. During the whole year the amount of work in the northwest portion of your property was limited by the terms of your contract with the United Verde Extension Min ing Company. Delays were also caus- ed by I. w. w. activities and by the abnormal difficulties in securing deliv- cries on equipment and supplies.
 "The working faces are now sufici- ently advanced from the shaft in sev- eral directions so that a number of drifts and cross cuts can be kept in Continuous operation on important ex- plora ion work. We have sufficient supply of compressed air for all devel- opment planned with two compressors, so that work can be continued in the most important places when compress sor repairs become necessary. It is anticipated that federal action with regard to L w. W. activities will .end saongly toward a more settled la DOT condition in Arizona.
 During the coming year We are planning to continue the scheme of exploration of the property previously announced. Since the capping which overlies the ore-bearing formations on nearly the whole area of the property prevents determination by surface in- ;pection as to which portions of the property are most mineralized, we pro pose to extend drifts and crosscuts as rapidly as possible to the more distant parts of the property. and from these workings run diamond drill holes across the formation in such d way as v dS bhC ter and extent, throughout the whole property, of the various rock forma- ions and areas of mineralzation. Sim lltaneously with this preliminary ex- ploration, we shall explore in detail the most favorable indications for ore thal have been encountered.
 Within few weeks we shall make connection with our crosscut east from the United Verde Extension workings on the Verde claim. This will greatly benefit the ventilation of the Columbia Shaft workings and increase the safe ty of operations by giving two outlets to the mine.
 We are planning to continue drift ing north after making this connection aud by the late spring of 1918 we hope to be able to connect with the end of our crosscut on the Compass claim, af- ter which we will be able to extend the development work on the north western part of your property without being dependent on working arrange ment through the ground of any other company.
