Rock & Mineral Collecting

Private Ore Piles

After commercial mining ceased, thousands of tons of broken ore remained inside the mine. Our experienced staff bring the ore to the surface and stay on hand to help you make some exciting finds.

Family-Size Ore Pile

3-4 adults  | 4 hours  |  $200

This large, 3 cubic yard pile is perfect for the whole family! In this type of pile, our main focus is finding copper specimens. If you have access to one, we recommend bringing a metal detector. Other specimens like quartz, calcite, feldspar and epidote can be found. Whereas silver and datolite are a little harder to spot! Our staff will be on hand to help you identify anything you find.

Children and seniors are welcome but must be specified. Please call the office for accommodations.
· Up to 2 additional children and 2 seniors

Single-Person Ore Pile

1-2 adults  |  2-4 hours  |  $100

The Single Ore Pile is built for 1-2 adults who are looking for an adventure without taking on an immense workload. The pile is 1.5 cubic yards (half the size of our family pile). In this type of pile, our main focus is finding copper specimens. If you have access to one, we recommend bringing a metal detector. Other specimens like quartz, calcite, feldspar and epidote can be found. Whereas silver and datolite are a little harder to identify!

Depending on the circumstance, and total number, children and seniors can be added to the pile for an additional cost. Please call the office for accommodations.

Tools provided: Finhoe, hammer, hand rake, bucket and running water. We recommend bringing a metal detector.

Tailings

1 adult  |  2-4 hours  |  $50  

On site at the Caledonia Mine is a tailings pile- often described as mining by-product or “leftovers”. This large area is a mixture of rock from the mining days and from used piles. Here you are able to bring your own tools and dig through the rock at your own leisure. We do not provide tools or guided assistance. It is considered an independent activity and offered only to adults. The area is turned over a few times a season, please call the office for details.

No children or seniors. Please bring your own tools.

Datolite Pile 

1-2 adults  |  1.5 cubic yards  |  2-4 hours  |  $200

We are pleased to continue to offer Datolite piles for the second season in a row! The nodule form, often described as “cauliflower-shape” can only be found in the Upper Peninsula and some parts of northern WI. This beautiful specimen is ordinary on the outside but absolutely stunning on the inside. Here at the Caledonia the most common colors are red, pink and white but more exotic colors are blue, yellow and green! The rock in this pile is much finer with a gravel-like consistency and is hand shoveled from nearly 1.5 miles inside the mine.

We provide you with a screen and shovel to meticulously sort through it. Our experienced staff will help you get the hang of identifying the challenging datolite. In addition to our staff helping you identify the rocks, we now have the ability to cut and polish your datolite on hand! This is a cash only service and is dependent on the staff present.

Tools provided: Shovel, screen, bucket and running water.

About The Caledonia Mine

A Proud Family Business

The Caledonia Mine is an underground, walk-in, copper mine, nearly a mile and half in length. The mine was opened in 1863, but only commercially operated until the mill burnt down in 1870. It changed hands privately over the years, with many attempts at mining. In 2013, Evergreen Explorations purchased the mine and currently offers the mine pile experience that you see today. This is a family-run business, started by the late Emmanuel Manos. His 7 children carry on his dream by removing the ore, running piles and educational programs, and cutting and polishing the rock found inside the mine.

THANK YOU for your interest in the Caledonia Mine, we cannot wait to provide you a unique, rock-collecting experience!
