Overview
Mission
The Minnesota mineral club is a non-profit organization devoted to the study of mineralogy, geology, paleontology and the lapidary arts. We are a social group that promotes rock, mineral and fossil education. Our mission is to encourage interest and education in geology, mineralogy, lapidary and earth sciences.
What it reported doing in 2025
2-day gem, mineral and lapidary show with vendor displays, educational exhibits, children's activities and lapidary demonstrations.
Operating model
- Revenue model
- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- Distribution model
- Direct operator. The filing allocates 98% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
SUPPORTED - The filed numbers largely add up and a large share of available resources goes toward mission work. Some filing-based governance responses are negative or unanswered and expenses are high relative to revenue.
