# Mount Ridley pushes high-grade scandium beyond Grass Patch resources Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/mount-ridley-pushes-high-grade-scandium-beyond-grass-patch-resources--a4ab8ec9-ae9f-4e7c-905f-9bd37aed1651 Original source: https://stockhead.com.au/resources/mount-ridley-pushes-high-grade-scandium-beyond-grass-patch-resources/ Publisher: stockhead Original announcement: 2026-09-23T02:45:10.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Mount Ridley Mines - Ticker: MRD - Exchange: Unavailable - Region: Unavailable - Primary commodity: Scandium - Secondary commodities: Gallium, Rare earths - Document categories: Drill results, Resource update, Metallurgy - Extracted: 2026-09-23 03:02:46 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Mount Ridley Mines has reported high-grade scandium re-assay results that extend the mineralised footprint by up to 8km beyond the current Grass Patch resource boundaries. The company also highlighted successful laboratory-scale metallurgical testwork showing 91.8% scandium recovery using its proprietary Selectro process. Reasoning: The announcement reports significant step-out drill results that extend the scandium footprint well beyond the current resource, alongside strong laboratory-scale metallurgical recovery results. - Positive factor: High-grade scandium intercepts extending 8km beyond current resource boundaries - Positive factor: New intercepts exceed existing Block 1 and Block 2 resource grades - Positive factor: Strong metallurgical recovery results \(91.8%\) reported from proprietary Selectro testwork - Positive factor: Significant resource scale \(946Mt\) provides a large base for expansion Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Phase 2 re-assays define mineralisation up to 8km outside current Block 1 and 2 boundaries. Evidence · text > Phase 2 re-assays extend high-grade scandium 8km beyond current resources **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The August resource upgrade is stated to be entirely in the inferred category. Evidence · text > all in the inferred category **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Proprietary Selectro testwork reported 91.8% scandium recovery. Evidence · text > reported 91.8% scandium recovery **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 6.

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.
