Show NIK Oil li m Two Shifts Equipped With Machine Drills Are Making Mak-ing Good Progress. I'ho work of driving the raise on the Tar Baby property, located in the Big Cottonwood district, for the contact between be-tween the ''black rock" formation and the white soluble limestone is being rushed ahead as rapidly as possible, according ac-cording to Charles H. Greene, president and general manager, who has returned from the property. The new plant of inac hiiHtry is K'vi'-K tfood results and two i-bitts ot miners are employed. The rai.se was started from near the end of the tunnel, which is in a distance of approximately lijoU feet from the portal. This was definitely determined when an engineer surveyed the workings work-ings recently. Before that it was believed be-lieved that the tunnel had reached the L!U00-foot point, that figure being arrived at by counting tho number of rails that had been laid from the portal to the breast. The raise is now- up a distance ot approximately fifty feet, and the contact, con-tact, according to the survey that has been made, should be reached by the miners with any round of shots. Kecently the miners have encountered a change in the formation, the roof of the raise being highly mineralized. Inasmuch In-asmuch as the contact along the surface shows copper ore with silver and lead valuos the management is pushing the work in tho raise with all possible speed. The miners are now breaking about five feet of ground per shift, and it is expected that this rate of progress will be increased in the near future. As soon as the contact is readied drifts will be started along it to explore ex-plore it on each side of the tunnel. The course of the tunnel is practically parallel to a porphyry dike that traverses trav-erses the property and that intersects the contact. This is believed to be responsible for the ore found along the contact on the surface, and considerable work will be done in the vicinity of where the dike intersects the contact. |
