Not illustrated. 1910 Excerpt: ... carried on in the early eighties, when the camp is said to have produced over $100,000 in silver. The principal mines are the Buckeye and Ohio, the Snyder, and the Page & Kelley. All these mines were inaccessible in 1908 except the Buckeye and Ohio, which was under water above the adit level. The deposits are in the main sheeted zones in rhyolite flow breccia, but altered andesite is exposed atfseveral places and it is probably the country rock for some of the ore deposits. The leaching of the country rock is extensive near some of the deposits, but is not so general as at Cornucopia. Pyritizatipn is, however, more pronounced in the wall rock and the ore at Good Hope contains a much greater amount of the sulphides. The Buckeye and Ohio mine is on Fourmile Creek near its junction with Atlantic Cable Gulch. The mine was operated from 1882 to 1884, and the ore was run through a 5-stamp mill 11 miles below the mine. This mill was equipped with roaster, pans, and settlers and employed the Reese River process. A small concentrator was built in 1903, but the treatment employed was presumably unsuccessful, as only a small amount of ore was put through it. On the surface above the adit level obsidian and other varieties of glassy lavas outcrop at several places. In the mine the rhyolite is a light-colored flow breccia, which is locally altered to a white claylike mass. Along a zone of movement it has been converted to gouge. The lode is composed of veinlets of quartz and sulphides, which include masses of the country rock highly altered and partly silicified. A tunnel driven on the vein for 300 feet southwestward gives a depth below the surface of about 65 feet. At some places stopes are carried to the grass roots and several winzes are sunk upon the vein. The ...
