HIGHLIGHTS
Historical drill data
The campaign conducted in 2014 comprised 55 holes for 7,000m of drilling (Figure 1).
This information builds on shallow historical drilling undertaken by Japanese International Cooperation Agency (JICA) in 1988 (up to a max depth of 50m), which included 41m @ 3.7% TREO, from 8m (JMT- 22) (refer DY6 ASX announcement dated 11/12/23). DY6 continues to compile an extensive exploration database at Tundulu and Nathace Hill comprising geological, geochemical, and geophysical data along with detailed geological mapping and surface sampling which identifies a large REE and apatite-hosted mineralised system.
Tundulu is formed of several hills in a ring around a central vent called Nathace Hill where the majority of the historic surface sampling and drilling was undertaken. The predominate geology at Nathace Hill is REE apatite, REE carbonatites and feldspathic breccia, and comprises a large inner agglomerate vent. Mineral rich carbonatite also occurs at Tundulu Hill east of Nathace and Makhanga Hill west of Nathace and is previously unexplored and prospective for REEs (Figures 2 and 3).
