Description of Business
PolyMet's primary mineral property and principal focus is the commercial development of its NorthMet Project ("NorthMet" or "Project"), a polymetallic project in northeastern Minnesota, United States of America, which hosts copper, nickel, cobalt, gold, silver, and platinum group metal mineralization. The NorthMet ore body is at the western end of a series of known copper-nickel-precious metals deposits in the Duluth Complex. An updated technical report and feasibility study published in March 2018 confirmed the technical and economic viability, positioning NorthMet as the most advanced of the four main deposits in the Duluth Complex: namely, from west to east, NorthMet, Mesaba, Serpentine and Maturi.
