Most of the land is within the Custer Gallatin National Forest, but the underground minerals are overseen by the Interior Department.

Zinke also is asking his staff to expand the agency's review to include other minerals such as oil and gas, coal, and phosphate.

Mining companies, ranchers and officials in some Western states said the Obama-era plan would impede oil and gas drilling.

Zinke signed an order Thursday requiring federal oil and gas lease sales be held in each state at least quarterly.
