The Minerals toolbox is a ‘work in progress’ and represents information available to date on this subject. Toolboxes are comprehensively reviewed and updated approximately every three years, with intermittent small updates and additions in the interim. To suggest new materials for inclusion, email Lisa Ronald at firstname.lastname@example.org. Date of last update: 10/17/2018.
This toolbox contains materials pertaining to the management of mineral resources within wilderness areas, as found in Sections 4(d)(2) and 4(d)(3) of the Wilderness Act of 1964. With a few exceptions, it does NOT include access to minerals. Those are covered in the Inholdings and Rights of Way Toolbox.
NOTE: Though the Arthur Carhart National Wilderness Training Center has made every effort to provide materials that are legally accurate, the laws affecting mineral resources in wilderness and their implications for management are extremely difficult to understand clearly. It is critical that you contact your solicitor or general counsel if minerals are an issue in your wilderness.
Definitions (with wilderness sideboards)
Locatable Minerals: Sometimes referred to as "hard-rock" minerals, "valuable" minerals, "lode or placer" minerals, or "rare or precious metals." It includes both base and precious metals, precious or semi-precious gemstones, uranium and other fissionable source materials, and other valuable industrial minerals. Locatable minerals on the federal mineral estate are usually removed from a claim without royalty or other payment to the federal government. Some high-value building stone types have been classified as locatable minerals.
Leasable Minerals: Those minerals for which a royalty is charged for their extraction from the federal mineral estate. This group includes oil; gas; coal; oil shale and other asphaltic materials; potash and other mineral salts; sodium; and sulphur. Geothermal resources are also managed under mineral leasing laws.
Saleable Minerals: Sometimes referred to as "common" minerals or "materials," this group includes sand, gravel, stone, pumice, and cinder. These are sold from the federal mineral estate. Small amounts of otherwise saleable minerals may be offered for "free use" to members of the public. There have been several arguments in court as to whether high-quality forms of these common materials should be classified as "saleable" or "locatable." This toolbox does not address that controversy.
Disposal: Disposal refers to the removal of mineral materials under sale or permit. Individuals, companies, organizations, or governmental entities cannot remove minerals without obtaining sale or permits. Disposal of minerals is regulated by 43 CFR 3600.
What kinds of minerals can be disposed?
Locatable Minerals: No! This includes gemstones, uranium and other fissionable source materials, and other valuable industrial minerals.
Leasable Minerals: No! This includes oil; gas; coal; oil shale and other asphaltic materials; potash and other mineral salts; sodium; and sulphur
Salable Minerals: Yes! This includes sand, gravel, stone, pumice, petrified wood, and cinder
Patented Mineral Claim: Surface and mineral rights of a valid claim of locatable minerals conveyed from the federal government to a person, persons, or corporation - essentially, private property. In a wilderness area, in order for both the surface and mineral estates to be conveyed, the patenting claim must be filed prior to the Wilderness Act of 1964 or the date of enactment of your specific wilderness. Claims filed after that date and before January 1, 1984 can be patented, but the surface will remain in the federal estate and "no use of the surface of the claim or the resources therefrom not reasonably required for carrying on mining or prospecting shall be allowed." Unlike patented claims outside wilderness, or within the wilderness but patented prior to designation, wilderness mineral claims patented after designation (but before January 1, 1984) must be "held and used solely for mining or processing operations and uses reasonably incident thereto" (Wilderness Act, Sec.4(d)(3)), which include "actions or expenditures of labor and resources by a person of ordinary prudence to prospect, explore...[or] develop...a valuable mineral deposit, using methods, structures, and equipment appropriate to the geological terrain, mineral deposit, and stage of development and reasonably related activities" (43 CFR 3715.0-5). In order to be patented, a valid wilderness mineral claim must have been located prior to December 31, 1983 or prior to the date the area was designated as wilderness, whichever came later.
Unpatented Mineral Claim: If not patented, a valid claim holds the right to extract locatable minerals from the federal mineral estate, but has no right to the surface other than "prospecting, mining or processing operations and uses reasonably incident thereto" (43 CFR 3712.1(a). Owners of unpatented mineral claims may be required to perform annual work on their claim to satisfy ongoing assessment or to otherwise hold the claim. In order for an unpatented claim to be recognized, it must be deemed to be valid and must have been located prior to December 31, 1983 or prior to the date the area was designated as wilderness, whichever came later.
Valid Mineral Claim: The requirement of a claim, either proposed to be patented or unpatented, to have a locatable mineral deposit of sufficient quality and quantity to justify a reasonably prudent person in the further expenditure of labor and money with a reasonable prospect of success in developing a paying mine. Not only must the deposit be of sufficient quality and quantity, the mineral must be able to be extracted, processed, and marketed at a profit. Validity exams for both the Forest Service and BLM are conducted by the BLM. In a wilderness, the claim must deemed both to be "valid" at both the time of the application by the claimant, and also to have been valid at the date of designation or December 31, 1983, whichever came later.
Split Estate (BLM Manual Rel. 8-68 7/13/98): Split estates refer to lands where title to the surface and mineral estate has been severed. Titles in this situation are usually held by different parties. In many instances the surface estate is not owned by the Federal Government but the mineral estate.

Relevant Information From Other Laws
Mining and water laws often reference each other. Mining can significantly deteriorate water quality for wildlife and people who live down-stream. States have their own laws concerning minerals and water that can be instructive for wilderness managers. Learn about mine safety and health and water.

Determination of Access
In order for any mineral to be extracted from the wilderness, the level of access to the valid right must be decided. In general, "reasonable" access must be given and it follows the same basic principles as access to inholdings.
Reasonable access to wilderness areas is typically defined as "means which have been or are being customarily enjoyed with respect to other such areas similarly situated." Access must also be the "minimum necessary." This means if supplies can be transported by horse but the right holder wants to use a truck, the supplies would need to be transported by horse.
The Wilderness Act does not create a private right of action regarding access to private property within a wilderness area. However, Section 5(b) indicated that when valid mining claims or other valid occupancies are wholly within a wilderness, ingress and egress is permitted so long as it is consistent with eh preservation of the area as wilderness.
Ingress & Egress
Since ingress and egress must preserve wilderness character, mechanical transport and motorized equipment can only be used if they are the minimum necessary. Indeed, "the use of mechanized transport ... or motorized equipment" need not be permitted unless it is "essential" to mining activities.
If access is granted, federal authorization must describe all access, functions, work, facilities, and activities related to prospecting, development, extraction, processing of mineral deposits, and reclamation of the mining operation.
