The A. E. Seaman Mineral Museum’s holdings include:

  • An extensive worldwide collection of minerals owned by Michigan Tech,
  • University of Michigan Mineral Collection jointly owned by Michigan Tech and the University of Michigan under the Michigan Mineral Alliance, and the
  • Guinness World Record 19-ton native copper slab on permanent loan from the State of Michigan, Department of Natural Resources.

There are about 4,000 specimens on exhibit. These change as new specimens are acquired, loaned to the museum from private collectors, and cycled from our extensive holdings.

The museum exhibits consist of the Thomas D. Shaffner Exhibit Hall, the Phyllis and John Seaman Garden, and the Copper Pavilion. To learn more about our exhibits go to Museum

Many people spend at least two hours for a visit even though it takes much more time to truly see everything offered in the exhibits.
