Includes two distinct ultramafic-dominated intrusions, the BTI and DEI, which host a number of major chromite deposits (e.g., Black Thor, Black Label, Big Daddy, Black Horse, Blackbird and Black Creek) providing geological resources totalling approximately 343 Mt at 32% Cr2O3 for the entire area. The BTI and the DEI are interpreted to have been fed by distinct magmatic conduits. Both intrusions are composed predominantly of a thick lower ultramafic series and thinner mafic upper series. The ultramafic series consist of dunite, peridotite (harzburgite), pyroxenite and chromite metamorphosed to lower greenschist facies.
