There are basically two types of claims that you will run into:
Patented mining claim:
is a mining claim on federal land for which the United States has issued a patent, transferring ownership of the claimed land—and, depending on the patent, its mineral rights—to the claimant.

In practical terms, patenting converts an unpatented mining claim into privately owned land. The owner may generally have rights to:

Possess and use the property, subject to existing restrictions.
Develop or sell the mineral rights.
Fence or control access, subject to easements and other legal limits.
Transfer the property like other private real estate.

Unpatented mining claim:
An unpatented mining claim is different: it does not transfer ownership of the federal land. It gives the claimant possessory rights connected to the discovery, development, and extraction of a valuable locatable mineral deposit, while the United States retains ownership of the land.

The federal government has generally not accepted new mining-patent applications for many years because congressional funding restrictions have prevented the Department of the Interior from processing them. Existing patented claims still exist, but they are relatively uncommon. A parcel’s patent status should be confirmed through the BLM, county land records, and the relevant land survey or title documents.

With all of the discussion here and in previous posts, lets do some questions and answers.

(Q) Can I make a claim just to go rockhounding on?
(A) No. You generally cannot validly file a mining claim merely to obtain a private rockhounding area.

A mining claim must be based on a valuable locatable mineral deposit and must be used for purposes connected with prospecting, developing, or extracting that mineral. Filing a claim simply to collect ordinary rocks, keep other rockhounds out, or reserve a favorite collecting spot could be challenged as an invalid claim.

(Q) How are some mines able to fence off the mining claim and post private property signs?
(A) A mine may fence an area and post “No Trespassing” signs when it has a legally recognized basis to control access, such as:

An active mining operation: An unpatented mining claim can give the claimant possessory rights to the area needed to prospect, develop, and extract a valid mineral deposit. The operator may restrict entry where people could interfere with operations or face hazards.
An approved operating plan: The BLM or Forest Service may authorize fences, gates, signs, roads, blasting zones, and temporary closures as part of an approved plan of operations.
Safety requirements: Open pits, unstable highwalls, blasting, explosives, and heavy equipment may justify fencing or agency-ordered access restrictions.
Private or patented land: A patented mining claim or privately owned mineral or surface estate may allow broader private-property access controls.
A lease or permit: State, federal, or private mineral leases may grant operational control and impose access restrictions.
However, an unpatented mining claim does not automatically make all federal land private. It generally does not let a claimant fence off land merely for recreation, prevent all public access, or use “No Trespassing” signs to expand the claim beyond its legal boundaries. The restrictions should relate to legitimate mineral activity, safety, or authorized facilities.
