Discrete phoscorite carbonatite vein 1.7% TREO at 366.8 m in drill hole HK22-013. The vein is cored by pink apatite, and cuts fenitized ijolite porphyry host rock, with large books of hydrothermal biotite and sulfide with trace amounts of chalcopyrite. Within the apatite vein are mm-scale crystals of monazite and parasite which contribute to the 1.7% TREO grade within this 1m sample. At top of frame is a grey-green phoscorite with smaller biotite crystals; there are no observed differences in grade or mineralogy between the two styles of REE mineralization.
