Encounter Resources Limited (ASX: ENR) reports air-core step-outs that extend high-grade niobium more than 1 km east of the Green resource footprint at the Aileron Nb-REE Project (Figure 1), while a shallow REE corridor is emerging along the southern carbonatite margin. The program is transitioning to 200 × 80 m infill at Green East and diamond drilling for metallurgy to define resource-ready domains.
