Additional Historical Drilling Results Confirms Tundulu REE Potential

DY6 Metals Ltd (ASX: DY6) (“DY6”, “the Company”), a strategic metals explorer targeting Heavy Rare Earths (HREE) and Niobium (Nb) in southern Malawi, is pleased to report the results of historical drilling that confirm the potential for the Tundulu Project to host significant rare earth elements mineralisation.

HIGHLIGHTS

• Additional data includes 7,000m of drilling (55 holes) undertaken at the Tundulu Project, southern Malawi
• Results confirm Tundulu’s potential as a significant REE project enriched in REE- mineralised carbonatites
• Exceptional high-grade intercepts include:¹
  • 101m @ 1.02% TREO, 3.6% P₂O₅ from surface (TU030)
  • 91m @ 1.09% TREO, 7.6% P₂O₅ from 46m (TU026)
  • 85m @ 1.04% TREO, 2.0% P₂O₅ from 22m (TU025)
  • 109m @ 1.06% TREO, 3.7% P₂O₅ from 53m (TU035)
  • 100m @ 1.09% TREO, 12.6% P₂O₅ from 30m (TU042)
  • 97m @ 1.35% TREO, 14.4% P₂O₅ from surface (TU050)
  • 125m @ 0.82% TREO, 2.3% P₂O₅ from 54m (TU078)
  • 95m @ 1.21% TREO, 0.92% P₂O₅ from 25m (TU110)
  • 87m @ 1.19% TREO, 0.43% P₂O₅ from 5m (TU071), including 15m @ 3.46% TREO from 73m
  • 74m @ 1.55% TREO, 4.4% P₂O₅ from 72m (TU043), including 11m @ 2.56% TREO from 84m
  • 31m @ 2.27% TREO, 0.64% P₂O₅ from 41m (TU048)
  • 30m @ 4.03% TREO, 0.35% P₂O₅ from surface (TU014)
• Drilling averaged 127m drill depth, with multiple holes ending in mineralisation (TU105B, TU110, TU094, TU087, TU073)
• REE mineralisation remains open towards southern and western directions of Nathace Hill and potentially extends beyond the boundaries of the previously established mineralised area over Tundulu Hill
• Results of recent reconnaissance sampling program align with historical data with visual observation of multiple carbonatite outcrops across the Tundulu project area
• Mineralogy and metallurgical assessment of recent comprehensive reports are underway using experienced REE and phosphate processing consultants in Perth with the aim to commence beneficiation test work in Q3
• Grant of Tundulu licence expected imminently

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).
