I couldnt find a comprehensive written account of the Union Hill Mining Company. Gold was discovered at Union Hill in 1854, the first recorded claim was in 1866 as Union Hill Gold Quartz Mine, and I have seen various Mining Stock Certificates for Union Hill Mining Company from the 1860s. The mine was worked as early as 1854. In the 1940s the mine was controlled by the Idaho-Maryland Mines Co. And at some point was owned by Empire Star Mines Co. Here are relevant articles from 1914 and 1915 Mining And Engineering World that relate to this historic Union Hill Mining Company Ledger: December 12, 1914, page 1104: Grass Valley: Reports from the Union Hill Mine state that high grade ore was cut in two places last week and that the company will soon be in position to start up the 20 stamp mill. Quartz showing free gold has been struck in the shaft at a depth of 710 ft. And in the east drift on the Georgia vein on the 300 ft level.
The strike in the shaft is regarded as very important and it is the opinion of Superintendent Cox that this is the Union Hill vein from which a heavy production was made on the upper levels. When first cut in the shaft the quartz was only a stringer but quickly widened out to 2 ft. The Union Hill has been one of the famous producers of Grass Valley.
The mine is well equipped with hoisting machinery, air drills, and a 20 stamp mill. The mine was acquired last summer by a group of San Francisco and Pasadena capitalists who organized a corporation known as Union Hill Mines to operate the property. Was put in charge and since Sept. 1 has had a large force employed sinking the main shaft. This shaft was started Oct.5 from the 600 ft. Level and the shaft is now down 710 ft.
A crosscut also was started on the 300 ft. Level to intercept the Georgia vein which yielded a big tonnage of good ore near the surface.
Johnson of San Francisco is president and general manager of Union Hill Mines and associated with him are E. Fluke, Tom Reed, and John MacDonald, all prominent capitalists and mining men residing in Pasadena.
June 5, 1915, page 886: NEVADA COUNTY (Special Correspondence) - Rich ore was found on May 25 in the Union Hill mine at Grass Valley, in a rise 25 ft. West of the main shaft. Bunches of rich ore were cut in the west drift after passing a reverse dipping vein containing no gold.
The rise was started where the ore was richest. At a height of 25 ft. The rise cut a slip extending horizontally into the foot wall. Of specimen ore was disclosed.After picking down as much of the quartz as could be loosened, a light charge was blasted. The hole made showed free gold on all sides, with 36 in. Of rich quartz in the back, following the regular dip of the vein. This part of the mine has never been prospected below the 300 ft. Level, although it produced a great deal of high grade ore in the old workings near the surface. The mine, which is a consolidation of the Union Hill Lucky and Cambridge mines, is bonded to a San Francisco company named Union Hill Mines, of which G. Johnson is president and manager. The company is operating 15 of its 20 stamps on ore from this development, and a shoot which was opened 200 ft.
East of the shaft, and 130 ft. San Francisco May 25, 1915. The item "Original SIERRA Nevada GOLD MINE LEDGER 1914 UNION HILL MINING Grass Valley RARE" is in sale since Sunday, August 25, 2019. This item is in the category "Books\Antiquarian & Collectible".
