Stamp Mill A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The process .

Since the mine owners maintained a five-stamp mill with two concentrators in operation full time during 1912, and a ten-stamp mill with two concentrators in 1913, it is unlikely that they chose to ship any of their ore to the copper smelter, although they had the option to do so if that process was favored.
When stamp mills are used for dry crushing, double discharge mortars are provided (see Fig. 50), and the screens are put low down, giving a small depth of discharge. These arrangements are necessitated by the difficulty of discharging the crushed ore from the mortar, the only means of doing this being the dashing of the dry ore against the screens, due to the fall of the stamps. Expediting the .
Modern USGS Topo Maps refer to the Mine as the Monte De Oro as well as the larger operation of the same name a few miles west. We visited the stamp mill to find it in a collapsing state with much equipment still in place. From the amalgamation table, to the stamps, and up to crushing equipment it .

Stamp Mills are necessarily built on the sides of hills as it is necessary to tier them on a downhill slope, each part of the process taking place on a lower level. Stamp mills are so called because of the "Stamps" that are used to pulverize the ore stone into powder in order to extricate the silver.

However, one of the mills was ordered for Dewey's operation didn't even get shipped to the mines as by this time it was determined that the current 10-stamp mill was sufficient to process the ore that was being mined. Ore values continued to decline at the Thunder Mountain mines until all of the large mines were closed by 1908.
The Joshua Hendy Stamp Mill, is enclosed in a stamp mill building and provides a full explanation of the gold extraction process from the ore. The mill, on its original site, is easily viewed from various points in the building. A working scale model graphically demonstrates the ore reduction process.
