Eagle Mine Summer Tours are Back June 6, 2022

We are excited to bring back our summer public tours! This is your chance to get a behind-the-scenes look at the nation’s only primary nickel mine.

We offer free tours of our Eagle Mine and Humboldt Mill on most Fridays from July to September. You must be 13 years or older to participate and an adult must accompany those under 18.

Registration is required. BOOK NOW

Eagle Mine Tour (3.5 hours)
Dates: July 8, July 22, August 5, August 19, September 16

The Eagle Mine Tour 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 where it is 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. Click here for directions.

Humboldt Mill Tour (2 hours)
Dates: July 15, July 29, August 12, August 26, September 9, September 23

On the Humboldt Mill Tour, 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. Visitors should be prepared to spend about an hour walking on-site, including up and down stairs and over metal grating.

Transportation is not provided for the Humboldt Mill tour. Tour participants will park in the Visitor Parking Lot at the Humboldt Mill and meet inside the Administration Building. Click here for directions to the Humboldt Mill.
