BLM Federal Mining Claims — Alaska
Active and closed federal mining claims managed by the Bureau of Land Management (BLM) for Alaska.
Why this data matters
- Active claims show where mineral rights are currently held — critical for staking and conflict checks.
- Closed claims indicate historic activity and often high prospectivity for re-staking.
- BLM is the authoritative source for federal mining claims in Alaska (LMaR).
