Northern Minerals Limited reported promising drill results from its Browns Range heavy rare earth deposit. The program unveiled new mineral targets and refined the geological model, boosting confidence in additional resource upgrades and supporting a long-term strategy for increased heavy rare earth potential.

Northern Minerals Limited has completed an advanced diamond drill program under the Exploration Incentive Scheme at its high‐grade Dazzler heavy rare earth element deposit in the Browns Range Project, Western Australia. The program, consisting of five holes totaling 1,346 metres, was designed to test deeper geological targets beneath the previously defined mineral resource. The drill campaign has revealed multiple styles of hydrothermal mineralisation, including xenotime–florencite veins and breccias, along with a newly identified volcanic unit composed of andesitic flows, tuffs, and sub‐volcanic sills. These results have enhanced the geological understanding of the deposit’s litho-structural framework, including the recognition of critical fault zones that potentially control mineralising fluid pathways. Key technical data indicate several significant intercepts with total rare earth oxide (TREO) grades typically measured above a cut-off of 0.15%. For example, one intercept reported 4 metres at 0.16% TREO with notable concentrations of dysprosium and other heavy rare earth oxides, while another hole returned intervals with TREO grades up to 0.52%. The program’s findings support an updated 3D geological model and will underpin a potential revision to the existing Dazzler Mineral Resource estimate, which already stands at an inferred tonnage of roughly 0.214 million tonnes at 2.33% TREO. The company's technical team has also identified new exploration targets along the unconformity between the Browns Range Metamorphics and overlying Gardiner Sandstone. Looking ahead, Northern Minerals plans to extend geochemical soil sampling over a 3-kilometre stretch and has secured additional co-funding to drill at the nearby Ripcord prospect. These efforts are aimed at expanding the understanding of potential heavy rare earth enrichment across the region. Market sentiment regarding this news tends to be positive. Bullish indicators include the successful illumination of deeper structural corridors, refined geological models promising additional high-grade targets, and the strategic co-funding arrangements which reduce the financial burden of further drilling. In contrast, cautious investors may point out that while technical results are encouraging, the exploration is still in its developmental phase, and further work is needed to fully delineate the extent and economic viability of the new targets. Overall, the drilling program has significantly bolstered confidence in the resource potential of the Browns Range Project, aligning well with the growing demand for critical heavy rare earth elements in clean energy and high technology sectors.
