# AIS: MATERIAL INCREASE TO GOLDEN PLATEAU MINERAL RESOURCE Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/ais-material-increase-to-golden-plateau-mineral-resource--d3fa15c0-349d-46b3-a1fb-a08393fdfb12 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03155673 Publisher: asx Original announcement: 2026-10-21T22:59:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-21T23:06:16.961Z Atlas analysis updated: 2026-10-21T23:06:16.961Z - Company: Aeris Resources Limited - Ticker: AIS - Exchange: ASX - Region: Queensland - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Resource update - Extracted: 2026-10-21 23:06:17 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Aeris Resources Limited announced a material increase to the Mineral Resource estimate for its Golden Plateau deposit, with contained gold increasing by 220% and contained silver by 200%. The update significantly boosts Measured and Indicated resources, enhancing confidence and extending potential mine life. While overall contained metal grew substantially, the average gold grade decreased, and the underground cut-off grade was lowered, contributing to the tonnage increase. Reasoning: The updated Mineral Resource estimate for Golden Plateau shows a substantial increase in contained gold and silver, with a significant upgrade in resource confidence, indicating a positive outlook for the project's future. However, the average gold grade has decreased, and the underground cut-off grade was lowered, which partially contributes to the tonnage increase. Some uncertainties remain regarding historical data and stope depletion. - Positive factor: Significant increase in contained gold \(220%\) and silver \(200%\) metal. - Positive factor: Substantial increase in Measured and Indicated Mineral Resources, improving confidence. - Positive factor: MRE is JORC 2012 compliant and signed off by a Competent Person. - Positive factor: Incorporates extensive new drilling and geological review. - Positive factor: Provides significant potential to extend the Cracow mine life. - Negative factor: Average gold grade decreased in both open pit and underground components compared to the prior MRE. - Negative factor: Underground cut-off grade was lowered from 1.5 g/t Au to 1.0 g/t Au, contributing to tonnage increase. - Negative factor: Some Inferred resources extend beyond drill data, relying on geological interpretation. - Negative factor: Risk of more or less stope depletion than modelled due to historical mining voids. Facts used in scoring: 44 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Total Mineral Resource tonnage increased from 0.64Mt to 3.0Mt \(370%\) compared to the previous MRE. Evidence · text > Total Mineral Resource tonnage increased from 0.64Mt to 3.0Mt \(370%\) **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: Contained gold increased from 63koz to 200koz \(220%\) and contained silver increased by 200% compared to the previous MRE. Evidence · text > contained gold increased from 63koz to 200koz \(220%\) compared with the previous MRE1 **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Measured and Indicated Mineral Resource have increased substantially and now accounts for 50% of the contained gold, materially improving confidence in the resource base. Evidence · text > Measured and Indicated Mineral Resource have increased substantially and now accounts for 50% of the contained gold, materially improving confidence in the resource base. **QP/CP Signed** Polarity: positive 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: Nicholas Spanswick is named as the Competent Person for the report and confirms he has read and understood the JORC Code \(2012\) requirements. Evidence · text > The information in this report that relates to Exploration Targets, Exploration Results or Mineral Resources is based on information compiled by Nicholas Spanswick. Mr Spanswick confirms that he is the Competent Person for all Exploration Results, summarised in this Report and he has read and understood the requirements of the 2012 Edition of the Australasian Code for Reporting of Exploration Targets, Exploration Results, Mineral Resources and Ore Reserves \(JORC Code, 2012 Edition\). **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The MRE is reported in accordance with the JORC Code \(2012\). Evidence · text > The MRE is reported in accordance with the JORC Code \(2012\) **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document announces an 'updated Mineral Resource estimate \(MRE\)' for the Golden Plateau deposit. Evidence · text > updated Mineral Resource estimate \(MRE\) for the Golden Plateau deposit **Grade Decline** Polarity: negative Definition: Average grade dropped >5% vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling. Why it applies: The open pit average gold grade decreased from 2.9g/t Au to 1.9g/t Au, and the underground average gold grade decreased from 3.2g/t Au to 2.9g/t Au. Evidence · text > reducing the average grade from 2.9g/t Au to 1.9g/t Au. **Cut-off Lowered** Polarity: negative Definition: Cut-off grade significantly reduced vs prior estimate — tonnage growth may be artificial inflation. Why it applies: The underground MRE is now reported at a 1.0g/t Au cut-off grade, whereas previously it was reported at 1.5g/t Au. Evidence · text > Previously, the underground MRE at Golden Plateau was reported on a block-by-block basis at 1.5g/t Au. **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: A significant portion of the resource, 1.7Mt at 1.9g/t Au \(100koz Au\), is classified as Inferred. Evidence · text > 1.7Mt at 1.9g/t Au \(100koz Au\) as Inferred. ## 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.
