Keweenaw Mineral Days joins the Copper Country Rock and Mineral Club's (CCRMC) Keweenaw Week and the Quincy Mine Hoist Association (QMHA) for a week of Keweenaw mineral-related fun (please see their websites for additional details). 

This year the Museum will hold its annual Mineral Surplus Sale and a talk by author, speaker, collector, and dealer Phil Persson of Persson Rare Minerals. Additionally, if you spend $100 in the Museum's gift shop and/or at the Surplus Sale you will receive 10% off your purchases at the museum during the week long event.
