Qualitative assessment of selected areas of the world for undiscovered sediment-hosted stratabound copper deposits

For each area in which this type of deposit may occur, we provide the main characteristics of the area, classification of known deposits by subtype, and a rank indicating the potential of the area to contain undiscovered resources.

Info
Platinum-Group Elements

The platinum-group elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial applications.
