Porter GeoConsultancy - Ore Deposit Description

The disseminated ore was the first to be developed in the trough zones towards the base of the differentiated flow. It is hosted by serpentinites, is defined by a 0.60% Ni natural cut-off, and has an average 15 to 25 wt% total sulphides comprising 65% pyrrhotite, 30% pentlandite and 5% chalcopyrite, accompanied by around 15% magnetite.

Banded ore that contains both fluorite and aegirine gangue minerals is the most abundant and widespread type of banded ore at the Main and East Orebodies of Bayan Obo. Because this ore type does not occur as a mappable unit, it is incorporated in banded ore types 2a (FH) and 2b (AeM) shown in figure 8.
