Drill core photo and QEMSCAN imagery from drill hole HK20-002, showing fine grain sodic alteration of primary biotite to Na-amphibole and Na-clinopyroxene with inclusions of Bastnaesite ((La,Ce,Y)CO3F), Burbankite ((Na,Ca)3(Sr,Ba,Ce)3(CO3)5), and Synchysite (Ca(LREE)(CO3)2F) in an apatite matrix. Magnetite grains are variably digested and found with disseminated pyrite and pyrochlore.
