Examples of fluorapatite, fluorite and apatite in drill core from the northern part of the Hecla-Kilmer complex, and associated with REE mineralization with gold shown in Figure 5. Upper photo: open-space vein with clear, euhedral fluorapatite with intercrystalline apatite and calcite; Middle photo: purple fluorite vein cutting carbonatite dyke and related spacially to 0.5g/t gold sample; Lower photo: fluorescent fluorapatite as disseminated grains and veinlets with carbonate in sodic altered nepheline syenite host rock
