What to Expect at the Argo Mill Tour

Plan to be on the tour at the Argo for an hour and a half to two hours for the full experience. Each professionally guided tour of the Argo Mill and Tunnel takes approximately 1 hour and 15 minutes. A gold panning lesson and experience, which lasts about 20 minutes, is also included with every Argo Mill and Tunnel tour.

Following the tour of the Argo Mill and Tunnel, each tour guest will get a gold panning lesson using a sample with real gold ore. You keep what you find!

Learn about the history behind the tunnel, mill, and mines.

Educators can use resources from the Minerals Education Coalition’s (MEC) in partnership with the Mighty Argo to provide a rich, hands-on historical experience. Because of the historic significance and impact that the Argo Mill and Tunnel played in local and state mining history, it was placed on the National Historic Register by the Department of the Interior in 1978.
