Photograph of drill core at 150 m in drill hole HK22-014. Nearly complete replacement of alkaline shonkinite host rock by potassic, fenite alteration consisting of magnetite-biotite-calcite-amphibole which is most intense around phoscorite (carbonatite) veins with semi-massive magnetite-apatite. Hydrothermal-magmatic shatter breccia and quench textures are evident. Similar hydrothermal vein, breccia, replacement and alteration textures, together with fluorite, are evident in intervals from tens to hundreds of metres long in all eight drill holes completed in the third drill program at Hecla-Kilmer in April-May 2022.
