Show THE UNION HILL MINE transcript NEVADA CITY CALA so quietly and unostentatiously las has the work been done that few people including those who live in the direct vicinity have any conception of the magnitude of the developments that have been accomplished at the union hill mine A prominent mining engineer who recently visited the property spending some time there stated that there is not a similar area that contains as many ore bodies and as much mineral as that of the union hill lucky vein intersected it has just come to light that the foot crosscut cross cut driven to intersect the old lucky vein on the foot level of the union hill was completed a few days ago nothing was said at the time of the achievement by superintendent graham for the reason that he wanted to demonstrate the value of the intersection before making it public the lucky vein had been intersected at the foot level some months previous the intersection being at a point of feet on the lucky vein the collar of the lucky shaft being feet higher than that of the union hill value of the diamond drill about the time of the intersection of the lucky vein at the level of the union hill the company arranged to have a diamond drill installed for prospecting purposes the diamond drill was used to good effect its efficiency as an aid to intelligent and scientific mining was demonstrated when it was discovered that the lucky vein continued east of the old works at the point of intersection for a distance of more than feet this was the motive for the starting of the crosscut cross cut at the level which has just been completed with the intersection ter section of the lucky vein the diamond drill proved that not only did the vein continue east for an indefinite distance but that it also carried values that were more than satisfactory to the management results are gratifying considerable work has been done on the vein under the direction of the superintendent and the result is exceedingly gratifying it has been proved that in each direction the values continue in the most satisfactory manner the company has feet of backs in virgin ground and the distance is fully 1000 feet from the point of intersection to the old lucky works the vein averages a width of tour four feet and some of the ore taken out shows gold gold freely there is also a liberal quantity of those minerals characteristic act of the veins and the district in which they were located drifting and up raising on the vein will be continued until it has been thoroughly opened up for purposes new mine Is developed the intersection intersect an of the lucky vein at a point 1000 feet east of the old workings and feet from the surface practically makes a new mine out of the union mill hill with such backs and a vein averaging a width of four feet according to the basi best computations it does not take much imagination to perceive that this old property which was paying dividends fifty years ago when the quartz mining was in ill an condition in this state has a roseate future there is now enough ore in sight to keep the present 20 stamp mill going for several years other veins intersected but the intersection of the lucky vein i is s not the only gratifying feature in connection with the development work at the union hill other veins of the system have been encountered proving that the property is one of the biggest in california today the greek vein parallel with the lucky and one of the most productive in the early history of quartz mining in grass valley was intersected by the crosscut cross cut driven on the level to tap the lucky the greek vein is susceptible to extensive development and is one of the valuable assets of the company another vein that has been intersected through the aid of the diamond drill is the georgia this vein lies in the of the union hill shaft and had been worked in the early days to a shallow depth only some time ago the diamond drill was put to work and a distance of feet from the shaft the georgia was discovered altis it is five feet in width and the ore taken out by means of the drill assayed nearly 8 to the ton A crosscut cross cut to open it up tip will soon be started increased milling capacity one of the possibilities of the near future at the union hill is an all increased milling capacity at the present time there is a 20 stamp mill which is one of the best in the state of its size there is ore enough already blocked out to keep this mill busy for a long time the major portion of the present supply comes from the 0 level now that the lucky greek and georgia veins have been intersected at the level and their development for purposes is only a matter of a short while it is evident that the crying need is for more stamps it is within the probabilities that twenty and possibly forty stamps will be added to the mill making it one of the biggest and most effective in the county it is the ambition of the company to have eventually stamps grinding away on oil the ore and it is believed enough ore has already been intersected to keep keel a mill going several years highly pleased at results president doe of the union hill company is highly pleased with the result of the extensive development work th that athas has been carried on since he assumed control of the property a few years ago he is delighted with the work vork of the diamond claiming that in the course of mine development such a device pays for itself many times over in the mistakes it helps the management to avoid especially when such work has to be executed through the means of long and costly cross cuts tungsten Is discovered another significant thing in connection with the development at the union hill is the presence of liberal quantities in the lucky vein of tungsten ore this is a rare and valuable metal that is not often found associated with gold ore mr doe was told by experts that if tungsten to the quantity of 2 per cent was found the discovery would be one of value an analysis made by one of the best chemists in san francisco proved that the vein carries tungsten to the value of 10 per cent in this connection it is interesting to know that the first tungsten ever found in california was discovered in the union hill in the by the late state mineralogist henry hanks may soon start sinking people of grass valley and the whole of nevada county will be pleased to learn of the valuable developments at the union hill they presage the opening up of one of the biggest mines in california and will be the means of adding greatly to the working force of the district and also to its output it is announced that sinking of the shaft may soon be resumed and that it will be continued to an all indefinite depth as an indication of the elaborate plans the coni company pany has in view 0 |
