Downhole graphic log of REE assemblages TREO and MHREO, along with critical metals Nb2O5 and Ta2O5, in top 400m of drill hole HK21-005 collared within the 3.5 mGal gravity anomaly at H-K. The highest grade REE mineralization occurs on the outer margins of a core of elevated Nb-Ta mineralization that is centred on a porphyry syenite dyke emplaced along a major structure evident in magnetic data. The same mineralogical relationship is shown in drill core in Figure 3 below.
