The federal mineral record holds 8,120 entries for New Mexico — 3,197 mines that shipped ore, 1,007 prospects that never became mines, 1,057 recorded occurrences. Below it: 2 places where you can legally collect.
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.

NM
lepidolitespodumeneberyl
State-designated locality · Free with permit · Open year-round in daylight, weather and road conditions permitting. The mine sits at elevation in the Picuris Mountains, so winter snow and mud can close the access road. The turn is poorly marked: a right just past mile marker 8 on NM 75 toward Penasco and Picuris Pueblo. On-site access is handled by the Griego caretakers, who may ask to see your signed form at any time.

thundereggsgeodesjasper
State park dig · Fee · Year-round, daylight hours. Spring and fall are kindest; the Little Florida Mountains bake in July. The separate Spring Canyon unit is described by the park as a hiking and picnicking area, not the collecting ground.

Yes — at places that allow it. This page lists 2 in New Mexico: 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 New Mexico'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.
