Ni-Co Laterite Deposits of the World—Database and Grade and Tonnage Models

Ni-Co Laterite Deposits of the World—Database and Grade and Tonnage Models

By Vladimir I. Berger, Donald A. Singer, James D. Bliss, and Barry C. Moring

Open-File Report 2011-1058 U.S. Department of the Interior U.S. Geological Survey


Ni-Co laterite deposits provide one of two major natural sources of nickel and cobalt. The economic importance of this deposit type expands in direct relation with industrialization of developing countries.

Mineral-deposit models are important in exploration planning and quantitative resource assessments for two reasons: (1) grades and tonnages among deposit types vary significantly, and (2) deposits of different types are present in distinct geologic settings that can be identified from geologic maps.

The latest geologic data and newly developed grade and tonnage models for Ni-Co laterite deposits in digital form are presented. Included are computer files with information about deposits from around the world. Text files allow locations of all deposits to be plotted in geographic information system (GIS) programs.
