# PNN: Maiden Exploration Target defined at Morro do Ferro Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pnn-maiden-exploration-target-defined-at-morro-do-ferro--c915103b-10ee-48e2-b521-2da42857eb58 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03142103 Publisher: asx Original announcement: 2026-09-21T23:55:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-22T00:29:36.349Z Atlas analysis updated: 2026-09-22T00:29:36.349Z - Company: Power Minerals Limited - Ticker: PNN - Exchange: ASX - Region: Minas Gerais, Brazil - Primary commodity: Rare earths - Secondary commodities: Magnet rare earth oxides, Gallium, Niobium, Thorium - Document categories: Drill results, Other - Extracted: 2026-09-22 00:29:37 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Power Minerals Limited has announced a maiden Exploration Target at its Morro do Ferro Rare Earth Project in Brazil, estimating 9.2 to 10.7 million tonnes at 7.8% to 9.2% TREO, including 1.3% to 1.6% MREO. This conceptual target is supported by extensive historical and current drilling, with plans for further work to advance towards a maiden JORC Mineral Resource estimate. The company acknowledges that unassayed drill holes and calculated density assumptions introduce some uncertainty to the estimate. Reasoning: The company has announced a substantial maiden Exploration Target for rare earths, providing a strong conceptual basis for future resource definition, despite some inherent uncertainties typical of this stage. - Positive factor: Maiden Exploration Target defined with significant tonnage and grade ranges. - Positive factor: Extensive historical and current drill data supports the model. - Positive factor: Verification sampling and twin holes confirm historical assay reliability. - Positive factor: Strong geophysical correlation with mineralization. - Positive factor: Project has priority status with the Minas Gerais Government. - Positive factor: Clear pathway outlined for a potential maiden JORC Mineral Resource estimate. - Positive factor: QA/QC procedures are disclosed and appear robust. - Negative factor: Exploration Target is conceptual and not a Mineral Resource, with inherent uncertainty. - Negative factor: Nine current drill holes remain unassayed, potentially affecting the estimate. - Negative factor: Bulk density for high-grade material is calculated, not directly measured. - Negative factor: Variography does not fully validate the southern projection. - Negative factor: Historical core recovery issues in saprolite not fully analyzed for grade bias. - Negative factor: No external audit of sampling techniques or data has been completed. - Negative factor: Gallium assay coverage is sparse due to analytical limitations. Low confidence — this extraction should be reviewed alongside the original source.

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.
