(46) Operational Stamp Mills in the USA (update 9/2016)

Existing Operable Stamp Mills (update 9/2016)

16th Operable stamp mill in the USA, as of September 23, 2016
I have put together a listing of operable stamp mills that I have physically seen or viewed videos of each mill in operation at various locations in the United States. There are some stamp mills that claim that their stamp mill is operable and runs, but it seems that is a relative term. They may only have one stamp engaged and manually pull the drive belt and the stamp drops. I do not consider that an “Operable or Running” stamp mill.

I have set some guidelines to determine if the stamp mill actually operates. The following are the requirements that I see that separates the static non-operating mills from operable mills:
Driver The stamp mill must be driven by some type of drive mechanism. There is not required speed, but it must make the stamps drop and reset through the action of the cams. You may only operate the mill at 10 rpm, but as long as the stamps move this is the important result.
Mortar Box Feed The mill can be fed manually or by some sort of mechanized feeder. Originally none of the stamp mills had automated feeders.
Material Processing There needs to be a mechanism to get the material out of the mortar box. This is generally water, but there were some dry processes where the material is driven out of the mortar box. This process should separate the concentrates through a sluice, shaker or mechanical panning.
Some mills that I have observed partially demonstrate attributes, but they don’t make the mark. Even though they do not make the mark it should be recognized that the owners of those mills spent a lot of time and effort to get as far as they did with the restoration. There may be just a few actions for these mills to get into the category of operable. I will continue to search for mills that show the above characteristics. 

The following (16) stamp mills, I feel, make the mark with operability:




ARIZONA STAMP MILLS






Castle Dome 3-Stamp Mill
The stamp mill is located at the Castle Dome Mines Museum in Castle Dome, Arizona. The 3-mill mill was recently restored back to operation. The mill came from the Yuma area. Most of the artifacts on display in Castle Dome Mines Museum were pulled from the surrounding 300 mine shafts that were gouged into the landscape. The mines were originally a silver mines and during World War II they produced large amounts of lead for the war effort.
Other Equipment on Site Allen and Stephanie Armstrong bought remnants of a town in the mid-1990s, moved it to a remote spot northeast of the Yuma Proving Grounds, then restored/created replicas of 23 buildings and loaded them with artifacts from the region's mining days.
Dates of Operation Call for hours of operation and let them know you want to see the stamp mill run.

Cossack Millsite 20-Stamp Mill

The stamp mill is located at the Superstition Mountain Museum in Apache Junction. The mill has an interesting history, in that, it has been moved from its original location in Bland, New Mexico to Goldfield, Arizona and then to its present location at the Superstition Mountain Museum. This was quite a job to disassemble and move and reassemble the twenty stamps and four mortar boxes. One of the four batteries are operational on this mill. The other three are static displays. The stamp mill is fed by a jaw crusher that supplies a skip that takes the ore and dumps it into the feeder that feeds it into the mortar box.
Other Equipment on Site that Runs There are a number of displays to see at the museum including some original movie set buildings with significant historical value and many other mining artifacts.
Dates of Operation The stamp mill will be run once a month for visitors at the museum. You can contact the museum at 480-983-4888 for the specific run times.
Contact Information  For hours and directions, call 480-983-4888 visit on the Web at http://www.superstitionmountainmuseum.org or Email  smhsmuseum@aol.com

The mill is run by a 4 cylinder gasoline engine and has automatic feeders that delivers the material to the mortar box. It has sluice tables to separate the gold from the concentrates and a shaker table that further separates the gold from the concentrates. This process uses gold bearing ores.

Swallow Mine 5-Stamp Mill
The stamp mill is located at the Arizona Mining & Mineral Museum, 1502 W. Washington, in Phoenix, Arizona. This mill demonstrates all of the attributes of an operable stamp mill.  This mill was restored back to operation in late 2003 and has been running until the museum was closed on April 30, 2011. The mill is run by a 15 Hp electric motor through a jackshaft that reduces the rotational speed from 1730 RPM down to about 60 RPM. The mill has an automatic feeder that is fed by an ore bin. It has a water fed sluice table that collects the concentrates that are further classified by a 1940’s Goldwheel. Concentrates can also be reduced in a small Wifley table. This process uses gold bearing ores.
Other Equipment on Site that Runs The outside exhibits include an operable jaw crusher, Gardner Denver Mucker, a Goldwheel, a small Wilfey table and an incline with an incline or cart.

Contact Information MUSEUM PRESENTLY CLOSED There is presently no outside contact information for this museum. The museum has been closed since and there is not schedule for reopening the museum. The equipment is being maintained by volunteers that periodically exercise the outside running equipment. The mill is being maintained operable even though the museum is closed.
Location The museum is located on 1502 W Washington Avenue, Phoenix, Arizona.






Taylor Mountain Millsite 2 & 3-Stamp Mills
The stamp mills are located at Taylor Mountain north of Dolan Springs, Arizona. This is a private millsite and is operated by Bob Taylor, a very seasoned miner. There are two operational stamp mills that crush ore down to the consistency of sand and then passed on to shaker tables to extract the gold from the ore. The site was established in the 1990’s and continues to operate. A lot of his equipment is “homemade”, just like the old miners did it. He is definitely from the “old school” of mining.  An example is a shaker table that he designed and fabricated that has a Plexiglas deck. This is not standard, but he wanted to see his concentrates separation and the light shining under the table shows the separation of the black sand, the pink barite and the stringers of gold.
Other Equipment on Site There is a tremendous amount of mining equipment, many items made right on the millsite, including Murphy Spirals, jaw crushers, plunge drilling equipment and single cylinder engines that operate.
Dates of Operation N/A
Contact Information N/A
Location The millsite is in the Taylor Mountains north of Dolan Springs.

  1. There's a 5 stamp mill that was being restored in Winthrop, WA. The last time I saw it, probably 10 years ago, it looked like it was operable or close to it.

    I did some investigation and found that the stamp mill in Winthrop, WA is at the Shafer Museum. They periodically run a 2-Stamp, home made mill, but they do not process ore. You would not consider it "operational" mill.
    They have a number of other stamp mills including 3-Stamp Joshua Hendy triple discharge mill, a 5-Samp mill, a 10-Stamp Straub Mfg Co. circular mill and a Chilean mill on site. This is an excellent place to visit just to look at the various types of mills they have on display.

    Thanks you for the leads

  6. Charlie,

    June 24, 2017 we will have the unveiling of the Royal Stamp Mill in Philipsburg, Montana. This stamp mill was originally a 10-stamp mill from the Royal Mine in the 1880s, but due to its degradation the restored stamp mill now is just five stamps strong. Parts were scavenged from the two to make the one.

    We have some footage of it hooked up to a tractor for use, but it now powered by a very old gas engine that will make the mechanism go. The plan is to do the final tweaking on it and get it running on June 24, 2017 as part of the Philipsburg Sesquicentennial celebration.

    Our CEO at QSPNLive.com has a ton of footage of the stamp mill as it was being restored and of it running with the tractor. We'd love to have you out in June if you're able to make it.

    1. I would like to visit your mill when it is running. We should be able to add your mill to the operable stamp mills the USA.
