Show BETTER ORE Sill Oil COLUMBUS EX, Stringers Improve in Raise on Toledo Fissure as Contact Is Neared. Tlie me showing In the roof of the raise that Is being driven on the Toledo fissure in the Columbus Extension property, prop-erty, located In the L,lttle Cottonwood district, dis-trict, continues to improve as the contact con-tact is approached, according to a telephone tele-phone report made to the local offices yesterday by Superintendent Henry Barney. Bar-ney. A softer formation of limestone lias been encountered and the stringers of ore are becoming larger. The main breast of t he southwest drift on the same fissure is also showing Improvement. The raise was started in the southwest drift at about 275 feet from the main tunnel. The drift was driven on the Toledo To-ledo fissure for the purpose of getting underneath the mineralized area of the old Toledo workings and It is now out about 350 feet from the main tunnel. This work was started after tlie management manage-ment had encountered a stringer of high-grade high-grade lead-sllver-copper ore at the point where the contact between the quartzite and the limestone, known in the district as the Cardiff contact, wag intersected by the Toledo fissure. Due to the dip of the contact it was practically Impossible to handle the rock broken in an economical manner while following the stringer of ore. The management therefore started the drift to the southwest and later on began raising to the contact. Where the raise was started there was a thin seam of mineral showing and the fissure was very tight. Tlie raise is now up a distance of seventy feet and in that distance there has been a steady improvement im-provement In the ore showing as the contact con-tact was neared. .Due to the formation becoming softer an excellent rate of progress prog-ress is being made In the raise, the miners min-ers breaking about six feet of rock per day. Two shifts are employed. There has been a steady improvement also In the main breast of the southwest drift. The breast is heavily mineralized and tlie limestone Is filled with vug holes that contain mineral, Work is also to be continued in the near future on the Blue Bird raise to reach the quartzite-limestone contact where it is Intersected by the Blue Bird fissure. The encountering of a heavy flow of water at that point caused the management to abandon that work until that territory had drained. As soon as the raise has sufficiently drained the territory above the work In that section sec-tion of the property will be resumed. |
