Show FOOT WALLS OR SLIPS searchlight searchlight nevada A profound distrust of apparent foot or j hanging walls should be entertained by every mining man in this and neighboring districts deceptive slips are of frequent occurrence and when followed as wap walls have often led away from valuable ore bodies the case of the duplex mine in searchlight is very illustrative of this point the property was bonded by G F colton to the duplex company with a provision for absolute forfeiture of all improvements move fulfillment able or otherwise in case of non of the bond the holders of the bond proceeded to develop the mine and erect erected eda ten stamp mill besides many other improve undertaken wa ments the development W not values value all along the hanging wall the for 0 the bond was proving satisfactory the feinted and mr colton reentered re entered into possession of a fully equipped mine lie he immediately broke into the supposed wall and found excellent ore later booi 10 delving in the same direction he further f ther by running the opened up an ore body 01 mill has been busy for the past si sis amp ten months on high grade ore and there is every dl cation of the permanence of these ore bodies two further cases in m point are further noted in the news columns of this issue the mine in eldorado canyon after having yielded over was supposed to be worked out the vein had become small and values were discouraging the management decided to sink in the hope of catching another ore shoot As a preliminary step the shaft which had followed the rather changing dip of the supposed foot wall was straightened and in in the course of this work this wall was found to be but a thin casing of porphyry under which besides several feet of good milling rock was two feet of ore alering the ton while a streak of some inches sampled over A new foot wall was established and the development of the new ore body proceeded satisfactorily last week foot wall no 2 was broken through and manager gracey reports the discovery of two and a half feet more of high grade ore in place of the supposed I 1 country rock thus four and a half feet of I 1 very high grade ore and some good milling ore have recently been discovered in what was supposed to be a worked out mine an exactly parallel case is that of the silver legion this mine has been open for many years but it was only last week that the foot wall was investigated it proved to be valuable ore and the width of the new ore is not yet known other instances might be quoted to support the argument that it would seem a safe I 1 rule to call every wall a slip until proved by investigation to be the country rock underlying or overlying the vein and not a casing of porphyry separating two ore bodies |
