Northern Minerals identifies new HREE target zone at Dazzler.

Updated geological model boosts resource confidence.

Strategic step toward exploring Browns Range potential.

Northern Minerals (ASX:NTU) has released promising updates from its recently concluded diamond drilling program at the Dazzler Heavy Rare Earth Element (HREE) deposit, located within the Browns Range project in northern Australia. The five-hole, 1,346-metre program was co-funded through the Exploration Incentive Scheme (EIS), targeting enhancements in geological understanding and mineral resource confidence.

The Browns Range project is already known for its rich endowment in dysprosium and other critical heavy rare earths—materials essential to permanent magnets used in electric vehicles and wind turbines. The new drilling campaign at the Dazzler deposit has unveiled valuable geological insights, including the identification of multiple hydrothermal xenotime–florencite mineralisation styles. Additionally, a previously unrecognized volcanic unit was discovered within the Browns Range Metamorphics (BRM), marking a notable development in the region’s geological framework.

This newly identified unit indicates that the BRM sequence may represent an evolving volcanic arc system. Such a finding could reshape existing petro-tectonic models and open the door to expanded rare earth exploration. The program also delineated a new HREE target zone where andesitic and metasedimentary units converge—an area now characterized by intense alteration, quartz veining, and faulting, all of which are encouraging indicators for rare earth mineralisation.

Northern Minerals (NTU) has used this data to develop an updated litho-structural model that bolsters geological confidence and will support an upcoming update to the Inferred Mineral Resource estimate for the Dazzler deposit. This improved model also lays the groundwork for broader exploration along the key unconformity between the BRM and the Gardiner Sandstone.

In the words of Managing Director and CEO Shane Hartwig, the exploration has significantly advanced geological comprehension of the Dazzler system and its potential extensions, reinforcing the broader vision of discovering new rare earth deposits in the Browns Range region.

As the company remains a part of the ASX300 index, this development places it firmly within a group of companies actively shaping Australia's resource sector landscape. For those monitoring resource-driven opportunities among ASX dividend stocks, Northern Minerals' strategic advances highlight how ongoing exploration can contribute to the long-term growth story of the ASX300 cohort.
