Frequently Asked Questions
How many mining claims are there in Colorado?
Colorado has 14,560 active federal mining claims on record with the BLM — 11,835 lode claims (hard-rock minerals) and 2,279 placer claims (loose deposits like stream gold). Counts sync weekly from BLM MLRS.
Can I stake a mining claim in Colorado?
Yes — any US citizen (or company) can locate a claim on open federal land: stake the corners on the ground, file a location notice with the county, and file with the BLM. Annual maintenance fees apply. The ground must not already be claimed or withdrawn, which is why checking existing claims first matters.
Can I collect rocks on a mining claim in Colorado?
An active claim doesn't close the land — you can usually still hike and explore — but the claimed minerals belong to the claimant. Collecting them is taking someone else's property. Check whether a spot is claimed before you dig.
