Show THE PILOT KNOB MINE do silver and gold mines turn into copper this is a question that can be answered in the affirmative in a great many cases the highland boy and other kindred properties in bingham were worked for many years for the pr precious decious metal product and it is only of a recent date that we have been able to chronicle the very satisfactory output of that mine in copper bars possibly the largest property having a like outcrop and which has been worked for many years is the well known pilot knob property situate about two and a half miles from ely nevada no one ever expected to see a copper smelter built on the old relies relics of that silver mine but still capitalists have recently taken it up and the developments show astounding results the formation there is a carboniferous lime and quartz porphyry with gabbro dykes cutting through the formation these dykes stand nearly vertical the vein system is a contact lying between the lime hanging wall and porphyry foot wall the width of this porphyry is from to feet As an outcrop there were large masses of iron hematite chiefly showing small stains of carbonate of copper through the mass which runs several dollars in gold and silver per ton the area of this property at present consists of forty five claims comprising in all over acres the property has been gathered up by a promoter and is now owned and developed by kimberley bireau of the united verdi and associates they have at present five wor working kino shafts three of them equipped with engines and two with patent whims the main shaft at present is down feet with two cross cuts at the foot level one 92 feet long and one 75 feet the character of the ore at feet was native copper in the hematite the sulphides sulp hides were first struck at feet and to all appearances a very large body is being opened up no walls at present have ben been encountered A second shaft feet has been sunk the shaft haft is all in ore A third shaft feet is in ore and a fourth shaft 86 feet deep is in hematite iron mixed with ore and a fifth shaft is all in ore feet feel deep these shafts are scattered along the iron outcrop and representing a distance of at least 2500 feet in length the general average of the ore so far taken out from all the shafts is about 71 per cent but the ore from the bottom of the shafts represent a much higher value cross cuts are being driven in to the solid sulphides sulp hides A railroad of over miles is projected parties are upon the ground now carefully looking over the proposition and planning out future developments on a large scale truly it looks favorable for a second rush to the old mines of nevada as this instance named is not the only district in nevada where the old silver mines have been recently started up and large copper deposits found |
