A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining.
Geology - Gold Mines Desert Mining History 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 explained

One of the difficulties in dry crushing is the production and loss of dust, which is generally richer than the bulk of the ore, for the reason that the sulphides are more brittle than the gangue. This difficulty is partly met by surrounding the crushing machine with an outer casing, and drawing off the escaping dust with air suction. Nevertheless, some dust escapes, involving a loss of values and also some injury to the machinery and to the health of the workmen.
Dry crushing by stamps is largely used in the treatment of silver ores by pan-amalgamation or by hyposulphite thiosulphate leaching. It was introduced on a large scale in 1894 for crushing the oxidised quartzose ores from the upper levels of the Waihi and other Ohinemuri Upper Thames Mines, New Zealand, and was finally abandoned in favour of wet crushing in 1904, partly owing to the fact that the character of the ore had changed with the working-out of the upper levels.
The photograph, probably taken by Martin M. Hazeltine of Baker City in the late 1880s, shows a stamp mill used to process gold-bearing ore near Cornucopia.
The mines at Cornucopia were developed beginning in 1885. Like many gold mining operations, the activity fluctuated widely, influenced by the quality of the ore, operating costs, the national economy, and gold prices. Cornucopiarsquos most prosperous years came long after the initial discoveries, during the 1920s and 1930s. The post office closed in 1942 after mining ceased.
