Maiden Sampling Identifies District-Scale Critical Minerals System at Blue

Dalaroo Metals Ltd (ASX: DAL, “Dalaroo” or “Company”) is pleased to announce the results of its 2025 exploration program completed at the Company’s 100%-owned Blue Lagoon Project in Greenland (Figure 1).

Highlights

• Maiden sampling program at the Blue Lagoon Project (Blue Lagoon) unlocks new Zirconium (Zr) and Rare Earth Elements (REE) potential district in Greenland.
• First sampling program at Blue Lagoon since 1979 has successfully returned elevated Zr + REE mineralisation. All 113 samples returned anomalous values, across a ~2.7km strike – indicating a highly prospective new critical metals district in Greenland.

Zirconium & Hafnium

• Exceptional high-grade Zirconium Oxide (ZrO₂) and Hafnium Oxide (HfO₂) surface samples include:
  • 4.42% ZrO₂ & 98ppm HfO₂ (Sediment Sample 26818D)
  • 4.09% ZrO₂ & 99ppm HfO₂ (Sediment Sample 26817D)
  • 3.82% ZrO₂ & 82ppm HfO₂ (Sediment Sample 26808D)
  • 3.58% ZrO₂ & 61ppm HfO₂ (Sediment Sample 26820D)
  • 3.13% ZrO₂ & 62ppm HfO₂ (Sediment Sample 26803D)
  • 2.85% ZrO₂ & 73ppm HfO₂ (Sediment Sample 26806D)
• 2% ZrO₂ and 40ppm HfO₂ encountered in auger holes and sediment samples across the entire ~2.7km strike, indicating a large-scale, broad and well mineralised target area.
• Hafnium is a critical semiconductor metal, which has become vital for supercharging the next-generation microchips and semiconductors, due to its high-K constant (dielectric constant) allowing Hafnium to store significantly more electrical charge than traditional SiO2 based semiconductors.
• HfO₂ has a K-constant approximately ~6x higher than SiO2, with one of the highest melting points of any compound, resulting in 1000x reduction in electron leakage through transistors versus SiO2 – underpinning the next generation of high-performing semiconductors¹.
• HfO₂ (High Purity) indicative sale price currently at AU $16,297/kg, reflecting its advanced chemical properties, increasing demand in high‑tech applications, and the scarcity of hafnium‑bearing minerals².
  • Blue Lagoon sampling has confirmed a ~2.7km strike with 2% ZrO₂ and 40ppm HfO₂ at surface, with potential for Hafnium grades to concentrate further at depth, subject to drilling confirmation.

Rare Earths

• The Blue Lagoon Project has returned high-grade REE results with consistent elevated Magnet Rare Earth Oxides (MREO)13 encountered at surface, with Total Rare Earth Oxide (TREO)13,16 grades highlighted by:
  • 8,079 ppm TREO with 29% MREO (Sediment Sample 26824D)
  • 6,491 ppm TREO with 27% MREO (Sediment Sample 26801D)
  • 5,668 ppm TREO with 27% MREO (Sediment Sample 26824C)
  • 5,654 ppm TREO with 27% MREO (Sediment Sample 26823D)
  • 5,519 ppm TREO with 25% MREO (Sediment Sample 26818D)
• Blue Lagoon has shown exceptional Heavy Rare Earth Oxides (HREO)14,15 enriched in Dysprosium (Dy2O3) and Terbium (Tb4O7) grades encountered at surface, unlocking a new completely untapped district in Greenland:
  • 886ppm HREO (Sediment Sample 26824D)
  • 752ppm HREO (Sediment Sample 26801D)
  • 742ppm HREO (Sediment Sample 26823D)
  • 682ppm HREO (Sediment Sample…
