Summary
Accent Resources NL re-released metallurgical testwork results for its Magnetite Range Project, confirming the technical viability of a dry processing flowsheet. Preliminary bench-scale tests achieved high-grade magnetite concentrates (up to 68.0% Fe) with strong magnetic iron recoveries (up to 98.2%). An additional wet cleaning stage further upgraded concentrates to over 70% Fe, providing technical support for a water-efficient processing route in the ongoing Pre-Feasibility Study.
Reasoning: This amended announcement re-releases previously reported preliminary bench-scale metallurgical testwork results for the Magnetite Range Project. The dry magnetic separation achieved high magnetic iron recoveries (up to 98.2%) and high-grade concentrates (up to 68.0% Fe), supporting a water-efficient processing option for the PFS. Wet magnetic cleaning further upgraded concentrates to over 70% Fe, but also showed the presence of deleterious elements. The results are positive for project viability but are not new information.

- High Recovery
- QP/CP Signed
- JORC Compliant

Facts used in scoring: 8
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Magnetic iron recovery for three high-grade samples ranged from 97.0% to 98.2%, exceeding the exceptional threshold for iron ore.
Evidence · text
“Overall magnetic iron recovery for the four tests reached 98.21%.”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: The testwork is described as preliminary bench scale outcomes, indicating early-stage testing.
Evidence · text
“These results are preliminary bench scale outcomes and are not a final process design or production forecast.”
QP/CP Signedpositive · Story-specific tag
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: The metallurgical information is compiled by Mr Aaron Debono, a Competent Person and Fellow of the Australasian Institute of Mining and Metallurgy.
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.”
JORC Compliantpositive · Story-specific tag
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: The metallurgical information is reported in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC).
Evidence · text
“Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.”
Deleterious Elements Presentnegative · Story-specific tag
Penalty elements (arsenic, antimony, etc.) or refractory concerns noted in the release.
Why it applies: Wet magnetic separation concentrate results include levels of SiO₂, Al₂O₃, S, and P, which can be deleterious elements in iron ore concentrates.
Evidence · table
“SiO₂%”
Context: J-UBIF-01
Stale Data Re-releasenegative · Story-specific tag
Historical results re-announced with no new assays or reinterpretation — low genuine novelty.
Why it applies: This announcement is an amendment to a prior release dated 30 September 2026, re-releasing the same metallurgical results with additional context rather than new testwork.
Evidence · text
“Accent Resources NL (ASX: ACS) (Accent or the Company) provides this amended announcement to its release dated 30 September 2026, titled “Testwork Confirms Technical Viability of Dry Processing Flowsheet”.”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("concentrate")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 4 distinct composites were tested

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
