Description:

Abstract:

Location, type, mineralogy, name, tonnage and grade, and geological setting for 120 deposits of this type. The US has no active nickel mines or nickel reserves.

Purpose:

This report helps to update a prior Ni laterite mineral deposit model by Singer (1986) for use in quantitative assessments of mineral resources at national and global scales.
