12 THE SUMPTER MINER Wednesday. March 4. 1903 r 9L TF You Want a Prospectus or Circular Printed in a Hurry, and for a Price Less Than You Ever Paid Before, You Will Have to Bring it to the MINER Office. We Set the Type With This Machine, and That is Why it Can be Done Cheaply and Quickly, THE SUMPTER MINER HUNTING FOR ORE BODIES. Large Sums of Money Wasted in This Vein Effort. A mining engineer of experience en torn into tlio mutter of expending largo miiiih n( money in iiiIiu'h in hunting for OrolMMlll'H, mill UXMIHtH SOIllOOf tho fill- lades of mining in tho following manner in tho Mining Kngiiicrr: It in not uncommon to woo lurgo huiiih spent in hunting oro iilong tho edgoH of some wnrkod-out oro shoot. In other eases tho Imrron voin ureas, between shoots h explored liy tho same close mid expensive network of shafts, wlnr.es uiul IovoIh tlmt would ho iihoi! within tho nreiiH of tho shoots thoimclvcs. Since shoots stand up uiul down in u vein, there in more rhiinco of striking ono hy horizontal thiin hy verticil! workings, lneideiilally the former aro much cheap er. Notwithstanding thin, the chief hopes in development work are apt to center on tho shafts and w hires, because those gain delith. Tim old and never dying delusion that mined always improve with depth, in partially reHM)iiMihle for thin. As ii mat ter of fact, mlnoH improve wlien any workings gets into mi oro hIiooI. Hut now mid then some shaft headed for the earth'H center chances to run into a shoot 011 its downward sIoh. Tho same shoot might have been found with little delay or oxHno hy a short level from tho Hhaft while it was shallow. Indeed, it may come to tho surface and a little skillful prospecting oxhho it there at the beitiuning of oiwratious. Nevorthe- proof of tho depth theory. When mining in Assuro veins, a part of tho development work is often wasted by being ""in off the vein." Tho filled and cemented fissure which constitutes a vein of this class is not often a simple, clear-cut break. Like any other frac ture in a solid mass, it lias branches, side bows and parallel crevices in every conceivable form. These may bo distrib uted through a widtli of SO to 100 feet and are more or less connected by inter lacing crevices. It ia not easy, and some times impossible at first sight, to distin guish the prinicipal ore-bearing fracture or "main vein" from the others. At ev ery split there is a chance of following the wrong clew and the sum total of such possible errors in n single mine is evident. Tho difficulties are increased by tho fact that an ore shoot frequently jumps from one crevice to another, and initio levels, therefore, pass hy it. In addition to the diillculties of identifying tho main crevice of ono vein, aro those which come, from tho existence of other veins close hy. Kvery time tho vein must he reach til anew hy a lower shaft, crosscut or tunnel, there is danger of mistake. There aro no tags on tho veins mid a large expenditure of good money on the wrong one is a familliar sight.
