The program included resource definition and extension drilling, with results up to 0.95% Rb2O, strengthening confidence in the project's scale and continuity. All data is now available for the preparation of a maiden JORC Mineral Resource Estimate, which will provide the first quantitative assessment of the rubidium system. Reasoning: The final assay results from the Mt Edon RC drilling program confirm broad and high-grade rubidium mineralisation, including exceptional intercepts, and demonstrate continuity and extension potential. This complete dataset is now being used for a maiden JORC Mineral Resource Estimate, which is a significant de-risking step for the project, supported by disclosed QA/QC and a Competent Person sign-off. - Positive factor: Broad and high-grade rubidium intercepts, including a peak of 0.95% Rb2O, confirm continuity and scale potential. - Positive factor: All assay results received for the 2026 drilling program, providing a complete dataset for maiden JORC MRE preparation. - Positive factor: Resource definition drilling confirms continuity within the core Sophie resource area, de-risking the project. - Positive factor: Extension drilling successfully identified southern continuation of mineralisation, indicating growth potential. - Positive factor: QA/QC procedures are disclosed, including certified lab and Competent Person sign-off, enhancing data credibility. - Positive factor: Lithium is identified as an associated byproduct opportunity, adding potential value. - Negative factor: True width of mineralisation is not known, which may overstate apparent intercept lengths. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 44 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release includes detailed QA/QC disclosure in JORC Table 1, mentioning certified lab \(ALS Global\), Competent Person sign-off \(Mr Henry Thomas\), and methods like duplicates, standards, and blanks. Evidence · text > Assay samples were dispatched to ALS Global in Perth, a certified laboratory. ... 13 Sample duplicates, 10 samples of Certified Reference Material \(CRM\), and 5 blanks were inserted into the sample sequence for QA/QC purposes. ... Mr Henry Thomas, who is a Member of the Australasian Institute of Mining and Metallurgy and is the Exploration Manager employed by Morella Corporation... qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Mineral Resources’. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The document explicitly states that 'Resource definition drilling confirms continuity of mineralisation within the core Sophie resource area', indicating infill drilling to raise resource confidence. Evidence · text > Resource definition drilling confirms continuity of mineralisation within the core Sophie resource area **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The release mentions 'extension drilling testing the southern continuation of the mineralised pegmatite system', indicating an effort to expand mineralisation beyond known limits. Evidence · text > extension drilling testing the southern continuation of the mineralised pegmatite system **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The JORC Table 1 commentary explicitly states that 'The true width of the mineralisation is not known, only down hole length is reported', indicating that only downhole lengths are provided without true width estimates. Evidence · text > The true width of the mineralisation is not known, only down hole length is reported. **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The company is progressing towards a 'maiden JORC Mineral Resource Estimate', which will be the first formal MRE for the project. Evidence · text > Complete drilling dataset now available for maiden JORC Mineral Resource Estimate preparation **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The document explicitly states that the maiden Mineral Resource Estimate will be JORC compliant, and the exploration results are reported under JORC Code, 2012 Edition. Evidence · text > maiden JORC Mineral Resource Estimate preparation **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Hole MER046 returned a peak interval of 2m @ 0.95% Rb2O, which is an exceptionally high grade for rubidium. Evidence · table > 0.95 Context: 2 **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The report clearly states the cut-off grades used for calculating intercepts: '0.05% Rb2O low-cutoff with an allowance for 2m of internal dilution' for main intercepts and '0.5% Rb2O low-cutoff with no internal dilution' for higher-grade intervals. Evidence · text > The calculated intercepts are generated using a 0.05% Rb2O low-cutoff with an allowance for 2m of internal dilution. ... Higher grade intervals are calculated with upto a 0.5% Rb2O low-cutoff with no internal dilution. ## Extracted facts Stored fact records: 44.

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.
