All claims are filed at the Colorado State Office. For information regarding filing a mining claim or annual maintenance fees, see the links below.
Mining in the Royal Gorge Field Office Area
Anyone intending to develop mineral resources on the public lands must prevent unnecessary or undue degradation of the land and reclaim disturbed areas. Surface Management of public lands for operations authorized by the mining laws are regulated under 43 CFR 3809.
Casual Use Activities
Casual Use means activities ordinarily resulting in no or negligible disturbance of the public lands or resources. Casual use generally includes the collection of geochemical, rock, soil or mineral specimens using hand tools; hand panning; or non-motorized sluicing. It may also include use of battery-operated devices for sensing the presence of minerals. Casual use does not include use of mechanized earth-moving equipment. See below for requirements specific to suction dredge operations.
Notification to the BLM is not required for casual use activities on public lands.
Notice Level Operations
Notice level operations typically include exploration activities. Exploration means creating surface disturbance greater than casual use and involves efforts to determine the extent, quantity, or quality of mineral values present, i.e. exploring for a mineral deposit. Exploration does not include activities where material is extracted for commercial use or sale.
These operations cannot cause greater than 5-acres of surface disturbance of public lands or involve bulk sampling in which 1,000 tons or more of presume ore is removed for testing.
A notice of your operations must be submitted to Royal Gorge Field Office 15 calendar days before you commence exploration. The notice needs to include the following information at a minimum:
43 CFR 3809.301 (b) – outlines the information your notice must include to be considered complete:
BLM may require you to provide additional information. You must notify BLM in writing within 30 calendar days of any change of operator, or associated mailing address, or corporate point of contact. BLM does not require that the notice be on a particular form. However, a voluntary form encompassing the required information is provided for your convenience. The form can be filled out electronically or printed and handwritten. Completed forms should be delivered to Stephanie Carter at the Royal Gorge Field Office (by hand, email or US mail).
Plan Level Operations
You must submit a plan of operations and obtain BLM’s approval before beginning operations greater than casual use, except as described under Notice Level Operations above. Any mine development proposal that is determined to fall under the definition of mining or operations proposed within an Area of Critical Environmental Concern are typically defined as Plan Level Operations under the regulations and subject to those parts of the regulations pertaining to a Plan of Operations, as opposed to a notice.
A Plan of Operations must be submitted to the Royal Gorge Field Office, who will then review the Plan of Operations within 30 calendar days of receipt. 43 CFR 3809.401 (b) outlines the information your Plan of Operations must include to be considered complete. BLM does not require that the plan be on a particular form; however, a voluntary form is provided below. This form coincides with exhibits required in CDRMS permits.
* * * NOTE – If your proposed operations involve the use of a suction dredge, prior coordination with the Royal Gorge Field Office is needed before beginning such use to determine whether you need to submit a notice or a plan to BLM, or whether your activities constitute casual use. Proposed operations involving the use of a suction dredge along the Arkansas River are typically classified as greater then casual use. Please contact the BLM Royal Gorge Field Office (RGFO) with the necessary information required for either notice- or plan-level operations (see above). * * *

Recreational Placer Mining in the RGFO and along the Arkansas River corridor
Recreational mining falls under recreational regulations (43CFR 8365.1-5), not surface operations under the mining law (these activities and regulations are described above; 43CFR 3809).
Per 43CFR 8365.1-5: Except on developed recreation sites and areas (or where otherwise prohibited and posted) it is permissible to collect from the public lands reasonable amounts of rock and mineral specimens for noncommercial purposes. Motorized or mechanical devices, except metal detectors, may not be used to aid in the collection of rock and mineral specimens.
Over the Counter Notification : For notice level operations at the Point Bar Placer Area, the following thresholds apply:
