Size-fraction analysis by ALS \(Perth\) indicates that scandium preferentially concentrates in the fine fraction, while iron is reduced, suggesting a potential for a simpler and more economic processing pathway. Further testwork, including magnetic and gravity separation, is underway to optimize scandium upgrade and manage deleterious elements like iron and alumina. Reasoning: Initial beneficiation testwork for scandium at Salazar shows promising results for concentrating scandium and reducing iron in the fine fraction, which could improve project economics, but these are preliminary findings from a single composite, and alumina is also concentrated. - Positive factor: Initial beneficiation results show preferential concentration of scandium in the fine fraction. - Positive factor: Beneficiation reduces iron content in the scandium-rich fine fraction, which is a deleterious element. - Positive factor: Testwork is focused on high-impact front-end beneficiation, potentially leading to a simpler processing pathway. - Positive factor: Testwork is being conducted by a reputable laboratory \(ALS\). - Negative factor: Results are preliminary and from a single composite sample, limiting representativeness. - Negative factor: Alumina, another deleterious element, is also concentrated in the fine fraction. - Negative factor: No final recovery figures or full flowsheet has been demonstrated yet. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 6 ## Classification and evidence **Recovery Improving** Polarity: positive Definition: Recovery improved versus a like-for-like prior test program on the same domain and route. Why it applies: Initial size-fraction analysis shows 61% of scandium concentrated in 51% of the sample mass, while iron is reduced, indicating an upgrade. Evidence · text > The fine fraction contains 61% of the scandium in just over half the sample mass, while carrying only one-third of the iron. This is encouraging because upgrading scandium and reducing iron ahead of leaching could improve the feed sent to extraction and purification. **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 a 'testwork program underway' using an 'indicative composite sample' and providing 'initial insight', not a pilot or continuous operation. Evidence · text > Substantial testwork program underway at ALS aimed at high impact front end beneficiation **Refractory Ore** Polarity: negative Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk. Why it applies: Iron and alumina are identified as deleterious components that affect downstream purification of scandium ore, implying processing complexity. Evidence · text > Iron and alumina are two of the deleterious components that affect downstream purification of scandium ore, therefore removing them prior to leach extraction will have positive impacts on the purification stages. **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: The testwork is based on a 'representative composite sample', indicating a single composite rather than multiple ore domains. Evidence · text > ALS \(Perth\) is testing an indicative Salazar composite sample to identify physical separation methods that may upgrade scandium before leaching. **QP/CP Signed** Polarity: positive Story-specific tag Definition: 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: Mr Aaron Debono, a Fellow of the Australasian Institute of Mining and Metallurgy, is named as the Competent Person for the metallurgical information. Evidence · text > The information contained in this announcement that relates to the metallurgical information at the Salazar Critical Minerals Project is based, and fairly reflects, information compiled by Mr Aaron Debono, who is a full-time employee of NeoMet Engineering acting for West Cobar Metals Limited and a Fellow of the Australasian Institute of Mining and Metallurgy. **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("heap leach"\) **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were tested ## Extracted facts Stored fact records: 6.
