The museum building houses antique mining equipment and steam engines. Some of the pneumatic machines are connected to compressed air so that they can be viewed in actual operation. The museum also includes a recreation of an old assay office and scale models of mines and mills.
Outdoor exhibits include live burros, a steam shovel, and an operating stamp mill for gold ore.
The museum maintains a research library on mining topics, available by appointment.
Other activities at the museum include lectures, rotating exhibits, and a twice-weekly farmers’ market.
