Throughout the year we are involved in an expanding set of events to highlight the worlds of mineralogy and geology.

Here are the events we currently have planned.

NEMA is calling for volunteers for this event! As a benefit to those that volunteer for FOUR or more hours, we’ll invite you to the private Volunteer Dine & Dig to be held on a date to be determined. Photos from a recent ‘Dine & Dig’ can be found below. If you’d like to volunteer for this or other NEMA events, please contact Jan at

Annual Fall Tailgate – September 14, 2024

“But I can’t make it to this one….” “I can’t vend this one…” or “I want more mineral tailgate fun!” Don’t worry – we’ve got you covered as usual with NEMA’s Annual Fall Tailgate taking place on Saturday, September 14, 2024, same times and activities planned! In the event of inclement weather, the fall tailgate will be moved to the next day, Sunday, September 15. Volunteers and dealers also wanted – get in touch!


If you’d like to participate as a vendor at either of the 2024 tailgates, please contact Jeff at, or by calling him at 207.232.4973 to learn more. (You must sign up with Jeff to vend at this event!)

SCAM ALERT! SCAM ALERT! SCAM ALERT! If a ‘Kim Allen’ (or anyone other than Jeff or Jan) posts that “we are still accepting vendors and to send all your info to her”, know that she/he/they/it is a scammer and/or a bot. This entity will try to get you to send them a check or other form of payment. It is also likely this scammer(s) will pop up in another persona – it’s a frequent problem with mineral shows. The ONLY way to vend at NEMA events (conference, tailgates, etc) is to contact Jeff directly. Do not be fooled! Email or call Jeff or Jan ASAP, or find us at in person if you have seen this scam in action. Click here for more about this issue on the NEMA FaceBook page.

NEMC Education Day: (Next event – TBD)

Each year in May (typically) students in grades 3-12 attend a fee-free day of fun and education. Between 50-100 volunteers help staff 20-30 different education stations where students engage in learning. Some are hands-on, such as sluicing for minerals and breaking rocks. Each year we have world class mineral specimens from the various areas of Maine and New England where most of the participants live. These specimens are on display with knowledgeable volunteers to explain what they are viewing. We have a large meteorite that is available not only to see, but to touch.

The Micromounters of New England bring their microscopes and small mineral specimens for students to look at. We have a large display case of fluorescent (rocks that glow under ultraviolet light) minerals which students love. We have had scientists showing a flame test to help identify minerals, a gem cutter teaching how “rough” is faceted into gemstones and many more stations. For more information on participating in Education Day, please click here.  To add your name to our growing group of volunteers, please contact us here.

Student Poster Contest: (Next event – TBD)

Along with Education Day we hold a research poster contest with the best posters on display at the New England Mineral Conference. The highest scoring submitted posters receive prizes, such as a week at a geology camp or a day of mining with one of the local miners. For more information on the Poster Contest, please click here.

Teacher’s Workshop: (Next event – TBD)

Our second day of mineral education with teachers was held in March of 2018 and it was very successful. Contact hours are offered, along with a great meal. Teachers are provided with authentic ways to bring education about New England minerals directly into their classrooms so the information is relevant to students and applicable to their lives. We plan to have multiple opportunities in this and future years. If you are interested, please contact Roland Charles here.

Oxford Fair: (Next event – TBD)

Over 1000 students come to the Oxford, Maine Fair every year in August for an education day event, and for several years, in great part to the provision of space in a building rented by Maine Mineral Adventures, we have participated by providing an informational table. As there is ample space for others to join us, anyone that would like to obtain selling space at the Oxford Fair, please contact Jody Matolcsy at 207.890.9753. To volunteer to help NEMA at the Fairs, please contact Jan Morrison here.

Traveling Rock Show: (Next event – TBD)

At Kid’s Day in September, around 1000 students, parents, and community members come and see some of the different activities and events that are available to them both through the school and in the larger community of Farwell Elementary School in Lewiston. 2017 was our inaugural year at this fun event. We provided a sifting pool where kids could take a bag of tailing materials and look for mineral specimens, and, in conjunction with Maine Mineralogical and Gem Society filled several tables with rock, mineral and gem displays (rock properties, showcase of gems, fluorescing minerals). If your school holds such an event, please contact us here to bring the traveling rock show to your event.

Maine Earth Science Day at the Maine State Museum in Augusta: (Next event – TBD)

For several years we have been participating in the Maine Earth Science Day at the Maine State Museum in Augusta. We provide a display and staff an informational table for the day. In 2017 there were over 1300 visitors including eleven school student bodies, countless homeschooling groups, and families from all over the state.

NEMA Goes Wild: (Next event – TBD)

On a wild Friday in the summertime, NEMA volunteers pack up and head to the Maine Wildlife Park in Grey and bring a condensed version of Education Day to the park. Kids are able to wash minerals and take home their finds. Even more come and ask questions at the various exhibits and games we set up, and we see several of them at the Conference in the spring.


  • We also send excited families toward membership at the various clubs throughout their states. We’ve had Californians, Virginians, Floridians, and many from across New England. We appreciate Maine Wildlife for inviting us; they are great folks, and we love working with them! If you’d like to volunteer to help with this event, please contact Jan here.

NEMA Rocks Lost Valley: (Next event – TBD)

One more time to play with rocks before the snow flies! Come to Lost Valley Ski Area in Auburn, Maine to join in the day’s worth of activities and food at Family Fun Day during Lost Valley’s Fall Festival. NEMA brings our mini education day where you can learn about geology and mineralogy, and kids 18 and under can wash local mine tailings to look for mineral specimens. All NEMA activities at Lost Valley are free of charge. Find us on Facebook or get on our mailing list to get updates.
