Mining Claims and Sites

Mining Claims and Sites

The Mining Law of 1872 makes public lands that are open to mineral-entry available for development and extraction of metallic and nonmetallic locatable minerals. The law also encourages mining companies to initiate exploration and development of such minerals.

A mining claim on Federal land gives a mining company exclusive rights to develop the minerals under the claim beginning on the date the mining claim was located. Within a mining claim, the surface lands remain open to the public for other multiple uses.

Miners may locate mining claims/sites to obtain exclusive rights, beginning on the date the valid claim was located, to develop the minerals under the claim.  Within a mining claim, the surface lands remain open to the public for other multiple uses.

A mining claim is located in order to acquire the right to develop the mineral values in a specified area.  Locating a mining claim requires a discovery of a valuable mineral. The claim is to have a substantial monument on each corner and at the discovery point within the mining claim boundaries. A certificate of location and map, along with the proper fees must be filed with the BLM Colorado State Office. 

There are additional requirements to maintain ownership of a mining claim/site.

If you are considering filing a mining claim, or are currently a mining claimant, important announcements and additional information regarding the Mining Law is available on this website by using the right navigation at the top of this page.

Patenting a Mining Claim

Since October 1, 1994, the BLM has been prohibited from accepting new mineral patent applications by a congressional moratorium.  The moratorium has been renewed annually through the various Interior Appropriations Acts.  The requirements for filing mineral patent applications may be found at 43 CFR 3860.


Surface Management Provisions for Hard Rock Mining

The term “3809 regulations” refer to the Federal requirements in place for locatable mineral mines and prospecting operations.

Before a claimant can engage in any surface disturbing activity, mechanized exploration, mining, residency, or site occupation, the party with the claim must file a plan of operations or notice of intent with BLM to conduct the appropriate review and permitting outlined by the regulations. The BLM requires an approved plan of operations for mining activity that disturbs more than five acres of public land or that could result in commercial mining. 

In addition to state of Colorado requirements, the Federal regulations identify 3-tiers of use on a mining claim based on surface disturbance and commercial use (sales). 

 CASUAL USE

Casual use prospecting includes those activities which cause very little or no surface disturbance. For example: collection of geochemical, rock, soil, or mineral specimens using hand tools; hand panning; or non-motorized sluicing. It also generally includes use of metal detectors, gold spears and other battery-operated devices for sensing the presence of minerals, and hand and battery-operated dry washers. Operators may use motorized vehicles for casual use activities only if the use is consistent with the regulations governing such use (43 CFR 8340) including following off-road vehicle use designations and temporary closures ordered by BLM. Casual use operations do not require notification of the BLM; except where specific land use or recreation area plans call for a recreational mining permit. You must reclaim any casual-use disturbance that you create.

NOTICE LEVEL

A person must file a Notice of Intent to Conduct Prospecting Operations (NOI) with the appropriate BLM field office, as defined in 43 CFR 3809 regulations. Notice level prospecting means any prospecting operation that is motorized, mechanized, uses explosives, or is reasonably expected to result in greater land disturbance other than is caused by the ordinary, lawful use of the land by persons not prospecting. The operator will be required to provide a financial guarantee warranty for reclamation costs of the prospecting operations which is filed and held by Colorado Division of Reclamation, Mining and Safety (CDRMS) in the form of a cash bond, or a corporate or insurance instrument. Surface disturbance is limited to 5 acres.

 PLAN OF OPERATION LEVEL

An approved Plan of Operations (mine plan) is required for exploration activities disturbing in excess of 5 acres, bulk sampling of 1,000 tons or more, and all proposed mining or milling operations (regardless of the acreage disturbed). A mine plan is required for any operation causing surface disturbance greater than Casual Use in special status areas as defined in 43 CFR 3809.11. Financial warranty must be supplied for all plan level operations.
