How to Stake a Mining Claim in Colorado
Colorado has 13,092 active mining claims on BLM land, targeting Gold, Silver, Molybdenum, Uranium. Staking a new claim requires following federal procedure under the General Mining Law of 1872 plus state-specific filing requirements.
The Staking Process
Verify land status
Use the BLM Mineral & Land Records System to confirm the land is open for mineral entry. Check for withdrawals, existing claims, and overlapping jurisdictions.
BLM MLRS Portal →Determine claim type
Choose one of four claim types based on the mineral deposit and your intended use:
- Lode claim — vein or rock in place deposits (e.g., gold in quartz)
- Placer claim — loose deposits (e.g., stream gold)
- Mill site — up to 5 acres for processing facilities
- Tunnel site — for tunnel-based exploration
Physically stake the land
Place legally recognized boundary monuments at the corners of your claim. GPS coordinates are now standard practice.
Colorado-specific: Colorado mining claim location and recording are governed by CRS Title 34, Article 43 (Location of Mining Claims). Federal requirements under 43 CFR 3832 apply on BLM-administered lands. [source]
File Notice of Location
File a Certificate of Location with both the county recorder's office and the BLM state office within 90 days of staking. [source]
Pay required fees
Initial filing costs approximately $274 per claim:
- $25 processing fee
- $49 location fee
- $200 annual maintenance fee
Source: 43 CFR 3833. [source]
Annual renewal
Pay the $200 maintenance fee before September 1 each year, or file a Small Miner Waiver if you hold 10 or fewer claims and perform $100 of assessment work.
Missing the September 1 deadline results in automatic forfeiture with no grace period.
