Photograph of drill core at 289 metres in drill hole HK22-011. Top row shows nearly 100% complete replacement of alkaline ijolite host rock evident in the lower row by potassic, fenite alteration consisting of massive, fine-grained, inter-crystalline magnetite, biotite, apatite and calcite. This core is within the 13 metre interval grading 0.94% TREO, with up to up to 2.3% TREO and 20% MH-TREO by ratio (middle and heavy Rare Earth Oxide), and containing up to 39.1% Fe2O3, 11.2% P2O5 over one metre intervals. The orange spots are resorbed potassium feldspar phenocrysts, the only remaining mineral of the ijolite host rock.
