For those not attending in person, we will continue to offer the presentations for free online viewing in our Video Library in the weeks following the event. This approach allows us to share the full program more broadly and ensure everyone can enjoy the content at their convenience.
Our annual Symposium Benefit Auction will be featured here when launched and live!
Check mineralauctions.com, complete with dozens of minerals, mineralia, and mineral collecting field trips.
The 2026 DMCS benefit auction will begin at least a week prior to the symposium and will end at 6:00 PM CDT on Saturday, August 22, 2026. You do not need to be present at the symposium to participate in the auction.
Big thank you to all our donors and bidders for helping make a difference in the mineral community year after year!
