A former Ag mine.
A post office known as Einstein Silver Mine was established in 1886 and maintained under that name until 1893, since when it has been Silver Mine or Silvermine. Its discovery of silver was made by Hiram N. Tong while following a set of turkey tracks. Hiram N. Tong bought the land and put a crew of men to work in 1862; the results of which were encouraging enough to interest a capitalist named William Einstein. In 1877 William Einstein bought out Hiram N. Tong and organized the Silver Mountain Mining Company and began operations. He planned to use the power of the river for his operations and built a dam across the St. Francois River. The remains of that dam can still be seen today and are in some of the photos shown here.
This mine is situated on the right bank of the St. Francois river, in section 12, township 38 N, 6 E. The deposit is unique and of special interest in that it consists of a well-defined vein of silver-bearing galena traversing Archean granite. No such deposit occurs elsewhere in Missouri or in the Mississippi valley.
Various accounts exist, some of them doubtless mythical, of the early discovery of this deposit nearly 70 years ago. It appears that some work was done here about 1855, and, later, the property passed into the hands of Messrs. Knox and Einstein. The first systematic operations appear to have been started about 1875, in the interests of these gentlemen. Aboat 1879, a stock company was formed and operations were greatly extended. A substantial dam was built across the river for water power, which still remains. A tunnel was driven about 20 feet long and an incline sunk to a depth of 180 ft., and between 200 and 300 men were given employment. Furnace, dressing works, boiler and shaft-houses, offices and other buildings were erected, and large sums of money must have been spent. This condition was maintained for a few years, when work was suspended, and the company seems to have collapsed. Everything is in ruin at the mine at present.
The deposit consists of a true vein traversing the granite in a direction somewhat S. of W., dipping from 45 to 60Β° to the S. The gangue is principally quartz, the metalliferous mineral argentiferous galena, though with this are associated iron and copper pyrite, and, as identified by Haworth [ 98, p. 20), fluorite, lepidolite, wolframite, and probably other minerals. In the wall rock, which is considerably altered at the contact, he recognized mica, leucoxene, small zircon crystals, and varying proportions of fluorite and topaz. The contents of the vein do not appear, so far as one can judge from the dump-piles, to have been arranged in layers, but were disseminated through the gangue. The thickness appears to have varied from 2 to 6 feet. The silver contents of the galens was doubtless in many cases high. The results of 58 assays show a range of from 1 to 148 ozs. to the ton; the average of 50 assays was 46 ozs. to the ton. A prospectus of the company states that, from 47 tons of the ore shipped, there was a yield of 2903 ozs. of silver. Some selected samples of ore ranged up to several hundred ounces of silver to the ton.
The conntry rock, as already stated, is granite, and this is of the common pink and highly feldspathic variety. This is traversed by vertical dikes of diabase running generally somewhat E, of N. One of them is as much as 6 ft. thick. Joint planes traverse the rock in various directions, breaking it up into prismatic blocks. One prominent system rans vertically in a N.-S. direction. Prof. Haworth reports that a number of smaller, but exactly similar velns are found on the west side of the river.
