WebChromitite seams are typically a few millimeters to several centimeters thick and therefore uneconomic for chromium. Instead, the chromitite in the Merensky Reef (Bushveld Complex) is mined as one of the largest PGE deposits on Earth, highlighting the important association between chromitite and PGE mineralization in LMI.
