LIMS concentrates containing 92-98% Fe2O3 have been produced. These concentrates may be saleable as a by-product as an iron ore concentrate. The WHIMS non-magnetic product contains ~83-88% of the ZrO2 from the original mineral samples. This result is consistent with the Silver Fox testing reported in a News Release dated January 12, 2021.
