</ HIDDEN 100FT AWAY FROM THE CHIMMINEY AS NOT TO GET MUGGLED OR HAVE ANYONE DAMAGE THE RUINS Welcome to Guymard Lead Mine. This mine was discovered in 1858 when workers building the new Erie Rail Road hit a large vain of lead. This mine was operated by the Erie Lead Mining Company. A 400 foot shaft was sunk into the earth with 2 adit levels to mine the ore and operated for about 20 years. At the time this was the largest vien of lead the world has ever seen. A smelting operation was built on site to process the ore. Today, all that remains of the operation is some building foundations a 100 ft chiminey, and a couple impressions in the earth that used to be the mine shafts. This mine has been sealed. Below is a news article From the New-York Tribune. Published: April 9, 1863 When the Erie Railroad was being built through the hills near Port Jervis, the workmen cut across a metallic vein, little suspecting that they had uncovered the richest lead-bearing lode ever discovered in this country, and perhaps any other. Recently, some New-York capitalists have bought the location, organized a company for working it, under the title of the Erie Lead Mining Company, and are now delivering large amounts of lead with as much regularity as the best-developed mines of Europe. Mr. THOMAS PETHERICK, the well-known mining engineer, has visited this mine within a few days, and writes to a friend as follows: "The vein varies in size from about two feet to over nine feet width, and is nearly perpendicular. It is a true vein, making its way through the hard sandstone rock of the country, which, to use a familiar mining expression, 'it masters.' Its appearance, composition and characteristics are such, in my estimation, as to justify great confidence in the successful and important results of extended operations. The shaft is about 32 feet deep, and has been sunk in rich lead ore from the very surface. In the bottom of the shaft the vein is over 9 feet wide. On its south wall there is a very rich "leader" of ore, with scarcely any admixture, (and the little there is of the matrix in it is of a very favorable nature as a symptom,) varying from 20 inches to 2 feet in width. The other part of the vein has also a very favorable appearance, the greatest part of it containing a considerable proportion of galena, and its frequent accompaniment in productive mines, "blende," or sulphuret of zinc. With suitable machinery for reduction and separation, this part of the vein can be worked with great advantage. The walls of the vein are well defined and regular, and on the north wall there is a good-looking "flookan," or clayey course, very important in regard to the facility of mining, and still more so as a favorable characteristic. Altogether, the appearance of the vein in this, the deepest opening, is, in my opinion, most satisfactory, both as to present productiveness and the future prospect. Nearly 85 feet from the shaft, there is a drift (about three feet higher than the top of the shaft,) which has been extended easterly about 64 feet beyond the open cut. In the west part of, and outside the close drift, very little below the surface, there is a course of galena about 50 feet in length; in the greatest part of which it was 3 to 4 feet wide, and at one point about 5 feet. I anticipate important results from the extension of a level at a proper depth. In extending the drift easterly, for some yards, the vein, though of a promising appearance, had not been productive. When I first saw it, it was small, about 20 inches wide at the face of the drift, of a favorable character, but with little, if any, ore; but on examining it subsequently, I found the vein considerably larger, being 2 feet 9 inches wide, of very promising appearance, and containing some galena and blende -- the latter a good indication of further improvement. There is also a trial pit, stated to be 12 feet deep, in which I am informed there is a good size, promising vein, but it was not accessible for my examination. Beside the ore already sent to market, and on the ground ready, or being prepared for it, there are considerable quantities of second-class and of inferior ore lying on the surface; but from there being a great deal of snow on the ground, I could not, well ascertain the quantity of ultimately available ore thus far mined. I apprehend, however, that it is from 100 to 110 tons of the first-class description, and that including the ore remaining on the ground to be reduced and prepared by machinery, the whole quantity mined to this time will exceed 160 tons, the value of which, at the present market price of lead, I estimate at about $20,000, at the mines. I am not aware what the actual costs have been, nor is that material, because the commencement of mining proceedings generally is attended with extraordinary expenses, much beyond the ordinary expense of a settled, regular management. I consider that under such management the proportion of profit on its production would very soon be unusually large for the most prosperous mines, say over 80 per cent. I wish to guard against any misapprehension arising from this observation, by remarking that this great rate of profit cannot be expected to be long maintained, notwithstanding that a great increase of aggregate profit may be reasonably expected to progress for along time; for, as the mine openings extend in different directions, it may be expected that in addition to such rich courses of ore as those reached by the present openings, large additional quantities of less rich vein stuff, mixed with the gangue, will, by the application of suitable machinery for their reduction and separation, be very profitably operated on, and lagrely increase the aggregate amount of profit."
