Type <strong>of</strong> Report & Period CoveredStaff from the U.S. Bureau <strong>of</strong> <strong>Mines</strong> (USBM) have completed a forest-wide mineral resource assessmentfor both metallic <strong>and</strong> non-metallic mineral commodities <strong>and</strong> an inventory <strong>of</strong> more than 1,100 mine <strong>and</strong> prospectgroups in Coronado National Forest, southeastern <strong>Arizona</strong>. Field investigations, which included mapping <strong>of</strong> minesites <strong>and</strong> collection <strong>of</strong> about 4,500 rock-chip geochemical samples from mineralized zones, were undertakenbetween the fall <strong>of</strong> 1988 <strong>and</strong> the spring <strong>of</strong> 1992. Assessment <strong>of</strong> the field data <strong>and</strong> publishing <strong>of</strong> the resultant14 resource assessment/mine inventory reports (one for each Management Unit <strong>of</strong> the Forest <strong>and</strong> one forest-widereport addressing industrial minerals} were completed between the fall <strong>of</strong> 1991 <strong>and</strong> the summer <strong>of</strong> 19<strong>94</strong>. Thisreport is a synopsis <strong>of</strong> all that work, <strong>and</strong> focuses on sites <strong>and</strong> commodities in the National Forest that are mostlikely to be targets <strong>of</strong> future mineral exploration <strong>and</strong> development. Much detailed economic analysis, historicalbackground, <strong>and</strong> all mine maps <strong>and</strong> assay data are omitted from this executive summary. For sites at which moredetail is desired, the individual mineral resource assessment/mine inventory report can be acquired from USBM,lntermountain Field Operations Center, P.O.
