This Bureau of Mines report compares the availability of federally owned minerals in Arizona with lands considered favorable for discovery of mineral resources to determine the extent to which federal mineral lands in such areas have been withdrawn by legal action or restricted by management practice. Of particular concern are restraints on federal lands in areas identified as highly favorable for occurrences of valuable mineral deposits. Excluding indian lands held in trust by the federal government, about 32 million acres, or 44%, of Arizona's mineral estate is federally owned. This total includes lands with partial federal mineral ownership. Approximately 16.5 million acres, or 52% of these lands, are available for location or lease. This includes 496,000 acres, or 62%, of the lands highly favorable and 2.6 million acres, or 57%, of the lands moderately favorable for locatable minerals in Arizona. All other federal mineral lands are either withdrawn or restricted and reflect a wide range of purpose, authority, and impacts on mineral exploration and development.
