Caledonia Copper Mine

Panning isn’t Just for Gold Anymore

Our experienced and knowledgeable staff will be on hand to help with collection techniques and specimen identification. This is truly a hands-on, educational experience, with the potential of bringing home a collector’s piece! Caledonia Mine is set in the side of a mountain overlooking the beautiful valley of the Flint Steel River. The mine is conveniently located 20 minutes from Ontonagon and 40 minutes from Houghton. The area is full of other fun things to do near by, from hiking the Porcupine Mountains to relaxing on the beautiful sandy beaches of Lake Superior.






Rock & Mineral Collecting

The mine is open from mid-May through early September with a limited number of dates available. Rock piles are built from the original ore left from mining days. Collecting is by advance reservation only. In addition, we offer rock and mineral collecting adventures for groups at other nearby mines.

















Private Ore Piles

After commercial mining ceased, thousands of tons of broken ore remained at the Caledonia Mine. We will build you a private ore pile and our staff will be there to help you make some exciting finds.
