IMC Rare Earths reports high-grade, near-surface terbium zone discovery at Itarantim Block H outside 1.1-billion-tonne resource

• IMC Rare Earths reported a new near-surface, high-grade terbium-rich ionic clay zone at Block H in Brazil’s Itarantim project.
• First drilling hit 7 meters at 5,695 ppm TREO from 2 meters depth, including 3 meters at 7,841 ppm TREO.
• Terbium averaged 38 ppm Tb4O7 across the interval, rising to 52 ppm in the higher-grade section; dysprosium reached 258 ppm Dy2O3.
• Initial ammonium sulphate leach tests recovered 64%-83% of terbium from the upper 3 meters of the enriched zone.
• Block H sits outside the existing 1.1 billion-tonne Mineral Resource; infill step-outs planned, with diamond drilling also set for Block D.
