Hawsons Iron completes dry comminution testwork supporting fully dry processing circuit
Independent consultants engaged to support reserve definition and PFS update
Project optimisation focuses on mine design, logistics, and sustainable waste solutions
Hawsons Iron Ltd (ASX:HIO), listed under the materials sector on the ASX 200 index, is progressing toward a revised Prefeasibility Study (PFS) for its Hawsons Iron Project near Broken Hill in New South Wales. This follows recent technical developments including the completion of dry comminution testwork and a comprehensive variability study.
The outcomes of the testwork have validated the viability of a fully dry processing circuit for the project. Hawsons has indicated that this circuit simplifies operations and offers a more environmentally aligned alternative to traditional wet processing routes. This approach also aligns with the company’s sustainable waste management initiatives, including the co-disposal of mine and dry processing waste.
Engineering consultants engaged to deliver project report
To support the next phase of development, Hawsons Iron has engaged Stantec, an independent engineering firm, to prepare a detailed project report. This document will serve as the technical foundation for defining a maiden ore reserve and progressing toward an updated PFS.
The report also provides insights into the viability of extracting secondary products such as hematite and silica sands, reinforcing a broader scope for resource utilisation. These findings feed into the ongoing optimisation of mine design, material processing, and logistics strategies.
Focus on cost efficiency and design finalisation
According to the company, the past half-year has been focused on understanding the technical behavior of the deposit and validating the effectiveness of dry processing methodologies. This body of work is regarded as essential for making informed, cost-efficient decisions on plant design and material handling systems.
The streamlined process configuration is expected to reduce operational complexity and environmental impact. Additionally, these advancements lay the groundwork for upcoming stages of development, including piloting activities to be conducted at GEBR Pfeiffer’s test facility in Germany.
Next steps in process design and feasibility
The piloting program is positioned as a key component in finalising the project’s process design criteria. These efforts are integral to preparing for a Definitive Feasibility Study that will build on the updated PFS and reserve definition.
Hawsons Iron has confirmed that all technical programs to date have been executed on schedule and within allocated budgets, marking consistent progress toward final design milestones for its namesake project.
The Hawsons Iron Project hosts one of the world’s largest undeveloped magnetite resources and is located in proximity to major infrastructure, enabling efficient transport and export planning as development advances.
