Revolutionary dry processing methods promise cost savings and environmental benefits for major NSW magnetite operation

Hawsons Iron Limited has achieved a significant milestone in sustainable mining technology, with recent test work confirming the viability of a revolutionary 100 per cent dry processing circuit at their flagship iron ore project.

The breakthrough findings, completed in partnership with engineering firm Stantec Australia, represent a major advancement in reducing both operational costs and environmental impact in the iron ore sector.

The Braemar Magnetite Province: A Geological Treasure

The Hawsons Iron Project sits within the globally significant Braemar Magnetite Province, a vast geological formation that extends across the border regions of South Australia and New South Wales.

Located approximately 70 kilometres southwest of the historic mining town of Broken Hill, the project occupies a strategic position at the eastern extremity of this remarkable iron ore belt.

This ancient geological formation represents one of Australia's most substantial magnetite deposits, with the Hawsons project alone hosting an impressive 4.4 billion tons of soft magnetite ore.

The Braemar Iron Formation extends northward into South Australia, where additional magnetite resources have been identified, making it a province of national significance for Australia's mining future.

The region's iron ore deposits formed over geological time scales, with the magnetite-rich formations representing some of the most accessible and high-grade iron ore resources in eastern Australia.

The proximity to existing infrastructure, including rail connections to Port Pirie in South Australia, positions the project advantageously for future export operations.

Technical Innovation: Dry Comminution Processing

The recent breakthrough centers on the successful testing of dry comminution technology, a process that eliminates the need for water in the critical size reduction phase of mineral processing.

Comminution, the mechanical process of breaking down ore into smaller particles to separate valuable minerals from waste rock, traditionally requires significant water resources and creates environmental challenges through tailings management.

Hawsons' comprehensive test work program and mineral resource variability study have demonstrated that their magnetite ore can be effectively processed using entirely dry methods.

This technological advancement addresses two critical challenges facing modern mining operations: water scarcity and environmental impact.

The mineral resource variability study revealed encouraging consistency across the deposit, with low variation in mineralogical composition, power requirements, and geochemical properties.

These findings suggest that the dry processing approach will remain viable throughout the projected mining life, providing operational certainty for long-term planning.

Environmental and Economic Advantages

The implementation of dry processing technology offers substantial benefits across multiple dimensions. From an environmental perspective, the elimination of water from the comminution process dramatically reduces the project's water footprint, a critical consideration in Australia's often water-stressed regions.

Additionally, dry processing eliminates the need for traditional tailings dams, removing a significant environmental risk and reducing the project's overall land disturbance footprint.

Economically, the dry processing circuit promises significant cost reductions through simplified infrastructure requirements, reduced ongoing operational expenses, and elimination of water treatment and tailings management costs.

These savings are expected to enhance the project's competitiveness in global iron ore markets while supporting more sustainable mining practices.

Strategic Position in Australia's Mining Landscape

Hawsons Iron Limited, formerly known as Carpentaria Exploration Limited, has transformed from a junior exploration company into a significant player in Australia's magnetite sector.

The company maintains majority ownership of the Hawsons Iron Project while holding additional magnetite interests throughout the broader Braemar Iron Province.

The project's location near Broken Hill, a town with over 130 years of mining heritage, provides access to skilled mining professionals and established supply chains.

The region's mining infrastructure, developed over more than a century of continuous operations, offers significant advantages for new developments.

Future Development Timeline

With the successful completion of the dry processing test work, Hawsons Iron is now advancing toward a maiden ore reserve declaration and an updated Pre-Feasibility Study.

The next phase will involve pilot-scale testing to validate the dry processing approach at larger scales before proceeding to final feasibility studies.

The company has indicated that discussions with potential strategic partners and off-take customers are progressing, supported by the enhanced project economics delivered through the dry processing breakthrough.

The timing appears favorable, with global steel producers increasingly seeking high-grade iron ore products that can reduce emissions in steel production.

Industry Implications

The successful development of dry processing technology at Hawsons could have broader implications for the global iron ore industry, particularly for projects in water-scarce regions or those facing strict environmental regulations.

As mining companies worldwide seek to reduce their environmental footprint while maintaining economic viability, the Hawsons approach offers a potential template for sustainable mineral processing.

The project's advancement comes at a time when the iron ore sector is under increasing pressure to demonstrate environmental responsibility while meeting growing global demand for steel.

The combination of high-grade magnetite ore and innovative processing technology positions Hawsons Iron as a potential leader in the next generation of sustainable mining operations.

As the project moves through its development phases, the success of the dry processing circuit will be closely watched by industry participants, regulators, and environmental groups alike, potentially influencing the future direction of mineral processing technology across the sector.
