With extensive geological and mineral resource information here, we estimated a mean of 25 undiscovered deposits of this type in this area, with a mean estimate of 95 million metric tons of copper.

Prospect- and mine-related features on USGS topographic maps

Symbols indicating mining-related features digitized from historical USGS topographic maps in the western part of the conterminous US. Includes prospect pits, mine shafts and adits, quarries, open-pit mines, tailings piles and ponds, gravel and borrow pit

Regional mapping of hydrothermally altered igneous rocks along the Urumieh-Dokhtar, Chagai, and Alborz Belts of western Asia using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data and Interactive Data Language (IDL) logical oper

Regional maps of phyllic and argillic hydrothermal alteration are presented on 10 separate plates available in either low or high resolution. A GIS package includes points features for potential porphyry copper sites also provided in tabular form.

Sandstone copper assessment of the Chu-Sarysu Basin, Central Kazakhstan

This study delineated permissive areas for undiscovered sandstone copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.

Sandstone copper assessment of the Teniz Basin, Kazakhstan
