Independent dry magnetic separation tests produced high-grade magnetite concentrates ranging from 66.3% to 68.0% Fe, with overall magnetic iron recoveries up to 98.21%. These results confirm the technical viability of a water-efficient dry processing flowsheet, which will be further evaluated in the project's Pre-Feasibility Study. Reasoning: Accent Resources has reported positive bench-scale metallurgical testwork confirming the technical viability of a dry processing route for its Magnetite Range Project. The tests achieved high-grade iron concentrates \(up to 70.3% Fe\) with excellent recoveries, providing a water-efficient option for the ongoing PFS. While the results are preliminary and require further validation at a larger scale, they represent a significant technical milestone for the project. - Positive factor: High concentrate grades achieved \(up to 70.3% Fe\) which are exceptional for iron ore, meeting or exceeding typical Blast Furnace Pellet feed specifications. - Positive factor: High overall magnetic iron recovery \(up to 98.2%\) and total iron recovery \(up to 91.2%\) demonstrated across multiple samples. - Positive factor: Technical viability of a dry processing flowsheet confirmed, providing a credible water-efficient option for the project's Pre-Feasibility Study \(PFS\). - Positive factor: Testwork conducted on four representative samples from different deposits \(Julia and Robb\), indicating some variability assessment. - Positive factor: Metallurgical results are signed off by a Competent Person \(CP\) under JORC 2012 standards. - Negative factor: The testwork is preliminary in nature and conducted at bench scale, not yet representing final process design or production forecast. - Negative factor: Further testwork and engineering studies are required to define an optimal flowsheet, assess commercial application, and evaluate energy use, equipment sizing, material handling, dust control, concentrate moisture, and operating costs. - Negative factor: Pelletisation performance and marketing requirements for the concentrates have not yet been assessed. - Negative factor: Deleterious elements \(SiO2, Al2O3, S, P\) are present in the concentrates, which may incur penalties or require further treatment. Facts used in scoring: 8 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: The testwork demonstrated overall magnetic iron recovery for the four tests reached 98.21% and total iron recovery up to 91.2%, which is strong to exceptional for iron ore. Evidence · text > Overall magnetic iron recovery for the four tests reached 98.21%. **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The testwork is described as 'bench scale outcomes' and 'preliminary in nature', indicating it is not yet at a larger, more representative scale. Evidence · text > These results are preliminary bench scale outcomes and are not a final process design or production forecast. **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: The testwork was conducted on 'four representative samples from Julia and Robb deposits', indicating testing across different ore domains.

Evidence · text > The information in this report that relates to Metallurgy is based on, and fairly reflects, information compiled by Mr Aaron Debono, a Competent Person, who is a full-time employee of NeoMet Engineering Pty Ltd and a Fellow of the Australasian Institute of Mining and Metallurgy. **PFS-Supporting** Polarity: neutral Story-specific tag Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The results provide 'technical support for including a dry processing route in PFS trade-off studies' for the Magnetite Range Project. Evidence · text > The results provide technical support for including a dry processing route in PFS trade-off studies. **Deleterious Elements Present** Polarity: negative Story-specific tag Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: The wet magnetic separation results table \(Table 3\) lists SiO₂, Al₂O₃, S, and P in the final concentrate, which are common penalty elements for iron ore. Evidence · table > SiO₂% Al₂O₃% S% P% Context: Table 3: Wet magnetic separation results **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).
