# BM1: Mt Ida Gold Resource increases 56% to 1.84 Moz Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/bm1-mt-ida-gold-resource-increases-56-to-1-84-moz--1314abba-a245-409a-8eeb-f8e70786a1e1 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03142486 Publisher: asx Original announcement: 2026-09-22T22:17:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-22T23:13:33.438Z Atlas analysis updated: 2026-09-22T23:13:33.438Z - Company: Ballard Mining - Ticker: BM1 - Exchange: ASX - Region: Western Australia - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Resource update - Extracted: 2026-09-22 23:13:34 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Ballard Mining has reported a significant 56% increase in the global Mineral Resource Estimate for its Mt Ida Gold Project in Western Australia, now totaling 1.84 Moz at 2.8 g/t gold. This update incorporates 125 km of new drilling and includes maiden resources for several regional deposits, achieved at a low discovery cost of A$36 per ounce. The expanded resource strengthens the foundation for a planned Feasibility Study, though a substantial portion remains in the Inferred category. Reasoning: Ballard Mining announced a substantial 56% increase in its Mt Ida Gold Project's global MRE to 1.84 Moz, driven by new drilling and maiden estimates for several deposits, at a low discovery cost. This significantly de-risks the project and strengthens the basis for a Feasibility Study, despite a large portion of the resource remaining in the Inferred category. - Positive factor: Significant increase in global Mineral Resource Estimate \(MRE\) by 56% to 1.84 Moz gold. - Positive factor: Cornerstone Baldock deposit resource increased by 35% to 1.36 Moz gold, maintaining high-grade tenor. - Positive factor: Maiden MREs established for Neptune, Pluto, and Astro-Quasar deposits, indicating new growth areas. - Positive factor: Low discovery cost of A$36 per ounce for the MRE increase. - Positive factor: The MRE update strengthens the technical foundation for the planned Feasibility Study. - Positive factor: JORC 2012 compliant estimate with sign-off from multiple Qualified Persons. - Negative factor: A high proportion of the total resource \(15.2 Mt or 75%\) remains in the Inferred category, which has lower geological confidence. - Negative factor: Some historical drilling data with limited QA/QC was retained for Inferred classification, potentially impacting confidence in those specific areas. - Negative factor: Estimates for Kestrel, Bombay, and historical tailings are unchanged and historical, not reflecting new work. Low confidence — this extraction should be reviewed alongside the original source. 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: The global MRE increased by 56% to 20.4 Mt, representing a significant increase in tonnage. Evidence · text > Global Mineral Resource Estimate \(MRE\) increases by 658 koz \(56%\) to: o 20.4 Mt @ 2.8 g/t for 1.84 Moz gold **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: The global MRE increased by 56% or 658 koz to 1.84 Moz gold, indicating a substantial increase in contained metal. Evidence · text > Global Mineral Resource Estimate \(MRE\) increases by 658 koz \(56%\) to: o 20.4 Mt @ 2.8 g/t for 1.84 Moz gold **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: Maiden MREs were reported for Neptune, Pluto, and Astro-Quasar deposits, establishing new resource bases. Evidence · text > Maiden MRE for Neptune, Pluto and Astro-Quasar deposits **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document reports an updated JORC 2012 Mineral Resource Estimate for the Mt Ida Gold Project. Evidence · text > Ballard Mining \(ASX:BM1\) \(“Ballard” or “the Company”\) is pleased to report an updated JORC 2012 Mineral Resource Estimate \("MRE"\) for its Mt Ida Gold Project **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The resource estimate is explicitly stated to be a JORC 2012 Mineral Resource Estimate. Evidence · text > JORC 2012 Mineral Resource Estimate **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: The MRE was completed by Michael Andrew and Susan Havlin from Snowden Optiro, and Todd Hibberd from Ballard Mining, all identified as Competent Persons. Evidence · text > The updated MRE was completed by Michael Andrew and Susan Havlin from independent consulting Group Snowden Optiro in September 2026. **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 total MRE, 15.2 Mt for 1.189 Moz, is classified as Inferred, indicating lower confidence. Evidence · table > 1,189 Context: 15,238 **Historical Estimate Only** Polarity: negative Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling. Why it applies: The Kestrel, Bombay, and historical tailings estimates are explicitly stated to be unchanged since the February 2026 update, indicating they are historical data. Evidence · text > Previously reported MREs at Kestrel and Bombay have not changed since the February 2026 update **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The expanded MRE strengthens the technical foundation for the planned Feasibility Study, which is a more advanced economic study than a PEA.

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.
