Greenland Resources Reassays for Magnesium and Finds Critical Minerals Including Rare Earth Elements

Executive Summary

• Greenland Resources reassayed 233 core samples from the Malmbjerg molybdenum orebody, detecting rare‑earth oxide (TREO) concentrations up to 579.5 ppm.
• The company will conduct petrographic studies on magnesium‑ and rare‑earth‑bearing minerals to evaluate potential recovery and its impact on project economics.
• CEO Dr. Ruben Shiffman highlighted the strategic opportunity to co‑produce rare earths alongside molybdenum, leveraging existing 35,000 t/d processing capacity and long‑term offtake agreements.

Key Details

• Sample set: 233 reasonably distributed core samples selected from five archived diamond drill holes with Mo grades above the NI 43‑101 feasibility cut‑off.
• Assay scope: 56 elements (including Mo, Mg, REEs) analyzed by SGS S.A., Vancouver.
• Rare Earth Results (ppm TREO):
• Lanthanum 4–92 (Avg 18.43)
• Cerium 16–194 (Avg 50.67)
• Praseodymium 2.8–22 (Avg 7.19)
• Neodymium 13–78 (Avg 30.05)
• Samarium 4.5–14 (Avg 7.89)
• Europium 0.06–1.37 (Avg 0.17)
• Gadolinium 3.6–12.5 (Avg 7.15)
• Terbium 0.48–2.25 (Avg 1.22)
• Dysprosium 2.5–14.1 (Avg 7.66)
• Holmium 0.48–2.88 (Avg 1.55)
• Erbium 1.33–9.08 (Avg 4.74)
• Thulium 0.19–1.44 (Avg 0.74)
• Ytterbium 1.30–10.2 (Avg 5.20)
• Lutetium 0.20–1.46 (Avg 0.75)
• Gallium (critical mineral): Avg 19.1 ppm.
• Next steps: Petrographic analysis of selected samples to identify host minerals for Mg and REEs; results will guide a larger assessment program for potential rare‑earth concentrate grades and recovery pathways.
• Qualified Person: Jim Steel, P.Geo., M.B.A., reviewed and approved the release per NI 43‑101 standards.
• Sampling & QA/QC (Nov 2025): 593.58 kg of material collected from secure government storage; field duplicates, blind certified reference materials, and blanks inserted every 20 samples; chain‑of‑custody maintained throughout.

Notable Quotes

“We have 20 years of profitable processing of molybdenum ore at a nominal throughput of 35,000 t/d with long‑term offtake agreements… we are encouraged to further investigate potential rare earth recoveries and capex and opex synergies with our molybdenum operation.” – Dr. Ruben Shiffman, CEO
