Photograph of drill core at 173m with 2.8% TREO in drill hole HK22-013. The pink area to left is high temperature, potassic alteration which displays elongate, quenched magnetite and biotite crystals in a pink matrix of apatite. The green area of calc-potassic alteration is quenched less, and includes amphibole together with euhedral magnetite and biotite crystals set in a green, apatite-rich matrix with carbonate and fluorite. Protolith alkaline igneous rocks including shonkonite and nepheline syenite porphyry dykes are completely overprinted and/or replaced.
