Abstract
The U.S. Bureau of Mines inventoried federal mineral lands in Idaho and classified them in detail, section by section, according to their availability for mineral exploration and development as affected by legal restrictions and agencies' management practices. The Bureau also identified known mineral deposit areas (KMDA's) and areas conducive to oil, gas, and geothermal resources. This information is shown on maps (developed in part by geographic information system, technology) that spatially compare the availability for mineral entry of federal land with these KMDA's to demonstrate the extent and severity of restrictions on mineral entry. Idaho contains 53.1 million acres, 35.7 million (67 pct) of which is federal mineral land. About 7 million acres of this land is within KMDA's that host medium- to high-value locatable mineral deposits; 36 pct of this land is available, 27 pct is slightly to moderately restricted, and 37 pct is severely restricted or unavailable. For the leasable minerals, about 1.8 million acres are within KMDA's that host medium- to high-value phosphate deposits, about 5.4 million acres are favorable for oil and gas resources, and 3.9 million acres for geothermal resources. The percentages of land availability are 30, 45, and 25 pct for the phosphate acreage, 38, 34, and 28 pct for the oil and gas acreage, and 43, 30, and 27 pct for the geothermal acreage.
