The Mohawk mill crushed rock from the Mohawk mine to separate copper from waste rock. The stamp mills of the Keweenaw peninsula used enormous amounts of water to separate metal and ore from waste rock. The water from this process was pulled directly from Lake Superior and the finely crushed waste rock was then dumped back into the lake. In 1888, the Elkhorn Mining Company increased its stamp mills to 25 and was working the mine some 800 feet below ground, bringing out about $30,000 in ore each month. The next year, the company sold out to a London syndicate for $500,000, which retained the name of the mine, remodeled the mill, and began aggressive development.

Placer Gulch and the Sound Democrat Mill

It was a 20 stamp mill built in 1889 to process ore from the Sunnyside Extension Mine. The mill was run by steam power. A tram was built in 1893 to carry ore from the upper mine levels in the basin above the mill. The remains of the brick foundation for the mill's steam boiler can still be seen. A number of other structure remains are evident.

The stamp mill was rebuilt in 1917 and after failed attempts to sell, the mine was abandoned. A mining boom in the early 1900s motivated a group of Chicago investors to capitalize a new mining operation, the Golden Reef Mine. A new ten-stamp mill was purchased for operation on Continental Mountain.

Here's the Standard mill, which processed ore from the Standard Mine. (The mine was originally named the Bunker Hill mine when it was first registered in 1861.) Most of the inner workings are still in tact. During the summer months Park Aides conduct a history talk and guided tour (for a fee) where you can see some of the interior of the mill.

The largest and most famous mine was the Camp Mine, the second largest gold mine in Colorado, established by Thomas Walsh in 1896. Two of the original claims, the Una and the Gertrude, had been worked for lead-copper-zinc ore, but when re-sampled by Walsh and Andy Richardson, showed a vein of quartz that assayed as high as $3000/ton in gold.

The stamp mill belonged to the Puritan (Union) mine located on the south side of Mint canyon, 18 miles east of Saugus and 4 miles northwest of Acton. The Puritan was a small scale producer during the Cedar Mining District (1870s-1900s) in the Acton area. Taken from LA County Office of the Assessor's site. The stamp mill is located on lot 4.

In 1938, his son William Donovan, Jr purchased twenty stamps from the Rock Point Mill (Nevada Mining, Reduction, and Power Company) in Dayton. He added these four 5-stamp batteries on the Donovan Family's third expansion of the mill, which completed an impressive bank of thirty of these industrial pistons, designed to pound ore into powder.

A marker at the base of the mill reads: Three Stamp Mill from the Red Ledge Mine. This three stamp mill was donated to the City of Grass Valley by Mrs. Stella Tracy, owner of the famous Red Ledge Mine near Washington, Nevada County, where this mill crushed tons of gold bearing ore for many years.

To begin with, this is a replica of what a stamp mill looks like at the mines, when the quartz comes from the shaft house it's brought on a trolley and it's dumped onto what they call a picking board and if there's any size of quartz that's too big or not appropriate to come down through the system, it's taken off of the picking board.

The next year he found a steam-powered, ten-stamp mill somewhere near the Colorado River and had it dismantled and hauled to the mine site. To provide steam for the mill, Ryan ran a two-inch pipeline 3.5 miles, from wells at his ranch to an earth and stone reservoir near the mill. Steam engines fueled by trees from nearby mountains were used to

Visible from the 14 Freeway in Acton, this 5-stamp mill was used to crush gold-bearing quartz that was extracted from the Puritan Mine more than a century ago. All closed up now, the Puritan was one of several gold mines owned by an investment consortium that included California Governor Henry Tifft Gage (1899-1903).

The stamp mill was rebuilt in 1917 and after failed attempts to sell, the mine was abandoned.
