Traditionally, the club sponsors an annual live auction of mineral specimens and mineral-related materials. The Covid pandemic inspired the club to sponsor several small online auctions as well.

The next auction is June 17, 2023! While we prepare the information for the next auction, see the BMC 2022 Live Auction page!
