The first company to work the present White Caps ground was organized in 1906, and the first production was made in 1911. A cyanide mill was operated in 1913-14, and treated 19,909 tons containing $381,053.49 in gold. At about 150 feet below surface the oxidized ore changed to a base sulphide, high in antimony and arsenic, and the mill could no longer be used, The company was reorganized in 1915, and development work actively carried on. A new mill of 100 tons daily capacity was started in September 1917, in which the are was roasted before cyanidation. This mill was operated until January1920, treating 59,056 tons of ore averaging $12.17 per ton, or $718,723 gross content. During 1920 and 1921 development work was continued in the mine, reaching the 800’ Level. In 1922. after further tests of the ore, the mill was again started and ran until early in 1924. Since early in 1924 no ore has been milled. A reorganization and. refinancing was effected in 1925. Development of the mine was continued, reaching the 1300’ level. Little was done on this level, due to bad ground and the company’s poor financial position. At the end of 1931 company, work was stopped and the mine was operated by leasers. -REPORT ON WHITE CAPSGOLD MINING COMPANY by JOHN L. DYNAN - February 6, 1934
WHITE CAPS OF MANHATTAN IN ORE
ORE SHOOT GETS RICHER
Getting the roasting furnace in place was a laborious process-- both building it and transporting it.
LESLIE H. WEBB, secretary of the Wedge Mechanical Furnace company of Philadelphia, left this morning for the east. This company is the maker of the roaster used by the White Caps, which is now on the ground at Manhattan.
GOES TO INSTALL THE BIG ROASTER
TUBE MILL FOR WHITE CAPS TO BE FINISHED IN THE NEXT THREE WEEKS
George Fresia, an Italian miner, was crushed to death by a rock slide in the White Caps Mine, after having spent the greater part of his life underground. He was sent up in a chute to loosen a body of ore which had become blocked so as to impede its descent, and while digging away at the mass the slide started, which overwhelmed him. Death was due to a blow on the temple, where a jagged rock struck him. [He was buried in] Manhattan, where he spent the past eight years, and for a long time was engaged in placering along the lower gulch.

This little jewel is hidden away in the hills east of Manhattan, NV. It's notable for its many buildings still standing, and it's giant furnace dominating the landscape. One of the buildings is losing its fight with gravity, and it's only a matter of time before it falls over. Beware the giant open shaft covered with logs near the roasting furnace; some say it goes all the way down to the 1500' level. You'd probably starve to death before you hit bottom. There is also the remains of a house perched on on the hill overlooking the site. Buildings are empty, but there is a lot to see.
And in case you're wondering about this roasting furnace, it's a "wedge furnace," described thus:
The Evans-Klepetko modification of the McDougall Roasting Furnace is the furnace employed at the Washoe and Great Falls Works of the Anaconda Company, and at many other important smelters. It consists of a cylindrical vertical shell of f-inch steel, lined with 8 or 9-inch bricks, with six hearths provided with openings alternately at the center and periphery, through which the ore is rabbled from hearth to hearth, and finally discharged. A vertical hollow shaft to which six arms, which are also hollow, carrying the ploughs are attached, passes through the center of the furnace. The ploughs are so set that they stir and push the ore towards the opening near the middle of the first hearth to the six openings at the periphery of the next, and so on alternately to the bottom, where the ore falls through a hopper into a truck or a bin below. The shaft arms are cooled by water circulating through them.
In the Herreshoff furnace the shaft and arms are cooled by air under pressure (see figure 15), otherwise it is similar in construction to the Evans-Klepetko.
The Wedge Furnace resembles generally the two furnaces just described, but the revolving central shaft is 4 feet in diameter. This shaft is protected from the heat by an external covering of brick, which revolves with it, and is said never to be too hot inside for workmen to enter and unbolt any of the arms. The shaft with its arms is entirely supported by six heavy roller bearings beneath the furnace, and is revolved by means of bevel gearing. It and the arms are cooled by air forced in by a fan or other means.
