Mineral history, not an invitation. This mineral history comes from a federal record of historic mines, prospects, and occurrences. It is not a list of places to collect. Historic mine sites are usually on private land, under active mining claims, or unsafe to enter — and often all three. The places you can actually collect are in the legal-access directory below.

Yes — at places that allow it. This page lists 2 in Florida: fee digs, designated collecting areas, and official localities, each checked against its source. Everywhere else, legality depends on who owns the land and what rules apply. Before any trip: check land ownership and current mining claims, get permission, respect closures, and never enter old mine workings.
Treat Florida's historic mines as history, not destinations. Most sit on private land or active mining claims, and old workings are dangerous even to walk. The mineral record on this page tells you what the ground holds — the directory tells you where you are welcome to look for it.
