# PLS: Pilgangoora Ore Reserve increases 31% in contained lithium Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pls-pilgangoora-ore-reserve-increases-31-in-contained-lithium--19e42341-1398-445c-aa4a-c8dbb3516339 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03153064 Publisher: asx Original announcement: 2026-10-15T21:17:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-15T22:36:57.041Z Atlas analysis updated: 2026-10-15T22:36:57.041Z - Company: PLS Group Limited - Ticker: PLS - Exchange: ASX - Region: Unavailable - Primary commodity: Lithium - Secondary commodities: Tantalum, Iron ore - Document categories: Resource update, Drill results - Extracted: 2026-10-15 22:36:57 UTC Narrative sentiment: 0.90 · Bullish ## Minestarters Atlas summary PLS Group Limited announced a significant 31% increase in contained lithium in its Pilgangoora Ore Reserve, now totaling 249.2 Mt at 1.24% Li2O, following the completion of the P2000 Feasibility Study and a maiden Underground Ore Reserve of 46.5 Mt at 1.50% Li2O. The updated Mineral Resource stands at 403 Mt at 1.33% Li2O, with an 8% reduction in tonnage due to a revised economic extraction assessment but a higher average grade. These updates reinforce the project's long-term production base and support the P2000 expansion. Reasoning: PLS Group Limited announced a substantial 31% increase in contained lithium in its Pilgangoora Ore Reserve, including a maiden underground reserve, and an updated Mineral Resource with a higher average grade. These updates strengthen the project's long-term production outlook and support the P2000 expansion plans, despite a slight reduction in overall Mineral Resource tonnage due to revised economic extraction parameters. - Positive factor: Significant increase in contained lithium in Ore Reserve \(31%\) - Positive factor: Maiden Underground Ore Reserve \(46.5Mt at 1.50% Li2O\) - Positive factor: Expanded Ore Reserve supports ~20-year operating horizon - Positive factor: Updated Mineral Resource with higher average grade - Positive factor: JORC 2012 compliant estimates - Positive factor: P2000 Feasibility Study and FID completed, supporting expansion - Positive factor: Improved metallurgical understanding and processing capability - Positive factor: Exploration results confirm continuity and potential for further expansion - Negative factor: Mineral Resource tonnage decreased \(8%\) due to RPEEE reassessment - Negative factor: Fe2O3 is a deleterious element requiring adjustment - Negative factor: Some approvals for expanded operations are still pending Facts used in scoring: 108 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 108.

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.
