Keweenaw Mineral Days 2025 - Annual Surplus Sale

Keweenaw Mineral Days: Restructured Surplus Mineral Sale
All are welcome! For details on the sale please read below, especially for returning attendees as this year is structured differently:

- The sale will be from 10am to 4pm
- There will be about 10 six-foot long tables with mineral flats. We will keep putting flats out throughout the sale.
- There will be 3 pricing tiers: tier one priced as marked, tier two 20% off, and tier three 40% off.

The sale will be held at the A.E. Seaman Mineral Museum back entrance on the cemented sidewalk area.

This year’s Keweenaw Mineral Days events do not require registration, though for planning purposes we are asking anyone planning to attend either event to RSVP through this quick online registration form.

All events are free and open to the public.
