Maine Minerals

Explore world-renowned geology and mineralogy in Western Maine.

Oxford County Maine is truly unique in its pegmatite formations, incredible variety of precious and semi-precious minerals. Our area has a centuries-long history as a prized mineral source for industrial applications, collectors, and academics.


You'll have a chance to dig and find minerals previously excavated from the mines. You won't leave empty handed, but remember, mining historically has demanded lots of time and patience to yield results!
