visited this high and lonely solitude that although within fifty miles of salt lake lahe city the big horns or mountain sheep still rind find a home there and the mountain ea eales eagles les have hitherto nested in its aeries adries as the last one spot where mans foot was never to tread the formation of this mountain near its base is granite or syenite and gneiss also porphyry midway toward the summit lies a belt of cambrian or weber quartzite 1800 feet in thickness on the upper contact of which rests a measure of clay slate and capping that about feet of carboniferous lime stone above this a measure of schist and still above this a third measure of the latter quartz ites the ores existing in this mountain are gold silver copper lead zinc antimony iron nickel cobalt and uranium the chief ore bodies so far discovered are in very prominent gold bearing fissures in the gneiss measures and silver bearing lead ores in the carboniferous limestone and clay slate near the summit of the mountain for thirty years the precious metals were known to exist here but it was only in 1897 that vigorous t steps were taken to develop the mineral veins that rise there to the surface in 1897 the first work of opening the hinr king solomon vein was begun and the following year the eldorado vein was worked upon this eldorado vein is a gold and silver bearing in lead vein lying between clay slate and blue lime and in places sending sendina immense bodies of ore into tha blue lime above the lead existing here runs from 20 per cent to 85 per cent silver to the value of f thirty ounces and from two to six six dats gold this vein where it is now being worked in the eldorado is from five et to seventeen feet in thickness and lies post ost like a blanket vein dipping into the buntain at a pitch of about fourteen degrees ad d rising ising with the country from N W to ill ea almost four miles the entire length of which shows values sufficiently high to make it pay for working the eldorado mine is situated on the west side of sierra madre mountain about feet below the summit suin mit known as eldorado peak the king solomon fissure breaks up through the quartzite into the slate and lime at this point and andi seems to unite with the eldorado flat vein at this point there seems to be a sort of funeral axis from which radiate forth the strong lines of either vein and at the point where work began on the eldorado clear bodies of silver bearing lead ore that runs 70 per cent lead to the t ton on comes clearly to the th surface continuing in strength and richness as work goes down until at a depth detthof of feet from the mouth of the incline the the vein presents one of the strongest and most beautiful ore bodies ever opened in any mine within the last twelve months

defined ore bodies may be traced along alono the mineral zone the most discouraging feature of these mines mines was the conditions existing when work of development first began for a distance of more than feet the surface of the country and approaches presented a succession succession of steep clift cliffs s and precipices points hundreds of feet apart had to be united by building up masses of masonry and by hanging bridges and at other points immense bodies of quartzite had to be blasted away and all this to construct train a good pack trail for a donkey in the spring of 1900 work on the
