Eagle Mine Tour

Eagle Mine Tour

The Eagle Mine tour (3.5 hours) is primarily a driving surface tour of the mine site with a walking tour through the water treatment plant. The mine tour does not go underground. You will see where the ore is brought up from underground and stored and loaded into the haul trucks. Other surface facilities include the storage area for development (or waste) rock, the backfill plant, the truck repair shop, and the water treatment plant. 


Participants meet at the Eagle Mine Information Center at 153 A West Washington Street in downtown Marquette, and bus transportation for the tour is provided.

Humboldt Tour

Humboldt Tour

On the Humboldt Mill tour (2 hours), you will see what happens to the ore after it leaves the mine site. The mill tour is a walking tour, beginning at the administrative office. The tour follows the circuit of crushing, grinding, and flotation processes, taking the ore from haul truck to rail car. Participants should be prepared to spend about an hour walking on-site, including up and down several flights of stairs and over metal grating. 


Transportation is not provided for the Humboldt Mill tour. Driving and parking directions are given at the time of registration.
