TINTIC CENTRAL . WILL SINK Vffi FfiOM 1025 LEVEL It has been .decided by the management manage-ment of Tintie Central that the nature which waa cut in that property east of She shaft and which has been found to be mineralized can best be prospected by sinking a winze from the lOi.Vfoot level within the mineralized territory. The theory upon which the company has bean operating is that the porphyry lying ly-ing to the south is a flow and the lime under that flow ran as reasonably be expected tobe ore bearing aa the limestone lime-stone in th district which is not coveted cov-eted by igneous rock, the ore bearing solution having been brought up in the Assures and spread out into the lime. On the IMS-foot level of the Tintie Central a crosscut was driven east in ths limestone area. The country rock near the shaft on that level appears to he rather tight, although it is cut by small norffi and eonth Assures which earrv some mineral. These fissures are, however, so small that they- are practically prac-tically negligible. About 20O feet east A the shaft the crosvut struck a fissure ihout thirty feet wide en, filled with rein material. This vein filling is thr typical iron manganese and other ma terial which is found in close proximitv m ore bodies in the eastern part of Tintie, and which is always associated with ores, although their presence does not necessarily indicate that values will he found. But it in by following just this kind of leads that ore is usually 'lif-covered. The peculiar feature of this PMing within the fissure is that the material is so leached that it has bul little weight. The ground is soft and caves readilv, so that the drift which S'es run a few feet within the fissure is about filled Vith the soft dirt which has come downAfrom the roof and the sides. With the opening of, thie fissure apd the finding of the 'above conditinna it, wns thought by the management that the values within the vein had been Uached and carried to greater depths. A close examination of that filling .fnows some leaching aetion. but as to what extent that process has been continued con-tinued is difficult to estimate. A station sta-tion is being cut alongside the fissure, and a winze will be etarted immediate )v. This wins will be sunk down until it is thought that the impoverished tone is passed, at which time " in all probability a short crosscut will be sent'out to the vein to ascertain the conditions there. It bad been contended by the management man-agement of Tintie Central that the limestone underlaid the porphvry and that the limestone was fissured by north snd south fissure, and further that these fissures were ore bearing. In the first two contentions khe work at the mine has demonstrated that tho theories the-ories have been proven. As to the value of thoa fissure, future work will alone determine, but the showing at the mine is one far better than is supposedly a great number of those who have never actually visited the property.
