In response to the growing demand for information on the global mineral-resource base, the U.S. Geological Survey (USGS) completed assessments for undiscovered resources of porphyry and sediment-hosted copper, platinum-group elements, and potash.
Understanding the global distribution of nonfuel mineral resources
The USGS conducts national and global assessments of renewable and nonrenewable resources to support decision making. Mineral resource assessments provide a synthesis of available information about where mineral deposits are known and suspected in the Earth's crust, what commodities may be present, and amounts of undiscovered resources.
After completing the first quantitative national mineral resource assessment in the 1990s, the USGS conducted a feasibility study to determine whether a global assessment was possible with current knowledge and technology. That study demonstrated that the work would be possible, if conducted in partnership with geological surveys and other interested organizations worldwide. The Global Mineral Resource Assessment Project started in 2002 as a cooperative international effort to assess the world's undiscovered nonfuel mineral resources.
The purposes of the study were to provide
- the first globally consistent and comprehensive analysis of selected types of undiscovered nonfuel mineral resources, and
- all nations with a regional and global context for evaluating their mineral resources, planning for new mineral exploration and anticipating the economic, environmental, and social impacts of mineral development, and making land use decisions.
The results of this global project are reported in the form of
- maps showing regions in which it is likely that there are undiscovered resources of copper, platinum-group elements (PGE), and potash,
- compilations of known deposits of these important commodities,
- descriptions of the characteristics of the known deposits, and
- estimates of the probable amounts of undiscovered copper, PGEs, and potash to depths of 1 to 3 kilometers below the Earth's surface.
The products of this assessment can be used as the foundation for
- potential mineral supply/sustainable mineral supply and development,
- environmental planning/anticipate potential impacts,
- land use planning/biodiversity, land-use conflicts, and
- economic planning/jobs, poverty reduction, economic development.

Global mineral resource assessment
Introduction
In response to the growing demand for information on the global mineral-resource base, the U.S. Geological Survey (USGS) is conducting the Quantitative Global Mineral Resource Assessment Project (GMRAP), a cooperative international project, begun in 2002, to assess the world's undiscovered nonfuel mineral resources.
Primary Objectives
The USGS conducts national and global assessments

Geology and undiscovered resource assessment of the potash-bearing, Middle Devonian (Givetian), Prairie Evaporite, Elk Point Basin, Canada and United States
The U.S. Geological Survey (USGS) assessed undiscovered potash resources in the Elk Point Basin in Canada and the United States as part of a global mineral resource assessment. The Elk Point Basin is a large, Middle Devonian (Givetian) intracratonic evaporite basin covering approximately 1,200,000 square kilometers (km2) and filled mainly with marine evaporite and minor clastic sedimentary rocks t

Assessment of undiscovered copper resources of the world, 2015
The U.S. Geological Survey completed the first-ever global assessment of undiscovered copper resources for the two most significant sources of global copper supply: porphyry copper deposits and sediment-hosted stratabound copper deposits. The geology-based study identified 236 areas for undiscovered copper in 11 regions of the world. Estimated amounts of undiscovered copper resources are reported

Qualitative assessment of selected areas of the world for undiscovered sediment-hosted stratabound copper deposits: Chapter Y in Global mineral resource assessment
A qualitative mineral resource assessment of sediment-hosted stratabound copper mineralized areas for undiscovered copper deposits was performed for 10 selected areas of the world. The areas, in alphabetical order, are (1) Belt-Purcell Basin, United States and Canada; (2) Benguela and Cuanza Basins, Angola; (3) Chuxiong Basin, China; (4) Dongchuan Group rocks, China; (5) Egypt–Israel–Jordan Rift,
