Frequently Asked Questions

Below are some frequently asked questions about the AMMNRE Museum. We want your input! If your question is not answered here, feel free to contact us.

Is the museum open? When is the opening date?

The museum is not currently open. At this moment, we do not have an official opening date. We are still in the development phase, focusing on building renovations and building our research and industry partnerships. We will keep the blog updated as we make progress.

What is the difference between this museum and the UA Gem and Mineral Museum in Tucson?

While both museums are in development under the University of Arizona, they are different institutions. The AMMNRE Museum was established as a natural resources museum that will showcase UA research and innovation in the mining, mineral, timber, livestock and agricultural industries. Our mineral collection serves as the state’s repository for minerals and mining artifacts, and is separate from that of the UA Gem and Mineral Museum.

Does the University of Arizona own the building?

Yes! In 2017, Senate Bill 1415 transferred ownership of the building and mineral collection fully from the State of Arizona to the University of Arizona. Read more about legislative history here.

Where is the mineral collection?

As of October 2019, the mineral collection is fully intact and safely back in storage at the museum. See this blog post for details about the move!

What happened to the ADMMR mine files?

When the Mining and Mineral Museum closed in 2011, the Department of Mines and Mineral Resources' mining files were transferred to the Arizona Geological Survey. Most were digitized and are available to search online at The AMMNRE Museum does not have access to the files.

What will happen to the outdoor mining equipment?

The outdoor mining exhibits are intact and regularly serviced thanks to Charlie Connell and the millmen. There are no plans to remove them. In fact, we plan to continue using the outdoor exhibit area to host public events and stamp mill demonstrations, with help from the Monday Crew volunteers. Check our blog for upcoming events!

What kinds of activities do volunteers do?

The AMMNRE Museum volunteers come from many different backgrounds and have different skills. We usually hold general volunteer days where we invite all volunteers to attend and then break into groups to complete different tasks, which can include working on the outdoor mining equipment, organizing parts of the mineral collection, sorting books, or helping with event logistics. While heavy lifting is sometimes involved, it is never required.

I have a rock/mineral/specimen that needs identification. Can you help?

Sure! While many specimens require in-person identification, we can do our best to help via email. Send a photo and additional info (location found, etc.) to Museum Curator Catie Sandoval at At this time, we do not offer appraisals.

Can you tell me how much my specimen is worth? Do you offer appraisals?

The museum does not offer appraisals and cannot determine the value of a specimen.
