GAO-22-105438 1 (2021-11-16)

handle is hein.gao/gaomkb0001 and id is 1 raw text is: Context and Federal Role
Hardrock mining operations consist of four primary
stages. These stages are mineral exploration, mine
development, mineral production, and reclamation (generally
removing mine structures and restoring disturbed lands).
Some stages can take place simultaneously. GAO-16-165
Mining is managed on federal lands using two systems.
Two federal agencies-the Department of the Interior's
Bureau of Land Management (BLM) and the Department of
Agriculture's Forest Service-are responsible for managing
hardrock mining activities on federal lands. The agencies
use two systems to do so, depending on the type of lands:
- The location system is generally used on public domain
lands, which account for 90 percent of federal lands.
- The leasing system is generally used on acquired lands,
which account for 10 percent of federal lands. GAO-21-
299, GAO-20-461 R
Most mining operations on federal lands are managed
under the location system. As of 2018, 97 percent of

hardrock mining operations were authorized under the
location system, and 3 percent were authorized under the
leasing system. GAO-21-299, GAO-20-461R
There were differences in views about the systems
among a broad range of stakeholders GAO interviewed
in 2020. For example, the following are characteristics that
these stakeholders generally described as advantages of
each system:
- Location system. Industry stakeholders' comments
reflected a general emphasis on certainty and assurance
that federal lands will be open and available for
exploration, that operators will be able to develop the
deposits they find, and that they will have ample time to
accommodate the mine development process.
- Leasing system. Tribal government and public interest
stakeholders' comments reflected a general emphasis on
equitably balancing mining with other land uses, the public
having the opportunity to participate in land-use decisions,
and mining not precluding other future uses of the land.
GAO-21-299

Mining systems differ primarily in the first three stages: mineral exploration, mine development, and mineral production
