The update includes 1,195,000 oz Au Eq Indicated and 1,190,000 oz Au Eq Inferred, driven by expansion in the Slab and York oxide deposits and the Santa Fe deposit. Reasoning: The update shows substantial growth in total gold equivalent ounces \(435,000 oz increase\) and expands both oxide and sulfide resource domains. - Positive factor: Significant tonnage and contained metal growth \(22% increase\) - Positive factor: Expansion of shallow oxide deposits - Positive factor: Identification of high-grade sulfide mineralization - Positive factor: NI 43-101 compliant reporting - Negative factor: Significant portion of resource remains in Inferred category Facts used in scoring: 12 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 12.

Unit: g/t Au Eq - Assumptions Disclosed: Yes #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-08-17T00:00:00.000Z Reasoning: Significant inferred sulfide resource. - Positive factor: Large scale sulfide resource Evidence · text > Inferred sulfide Resources total 28.42 Mt grading 0.86 g/t Au Eq for 782,000 Au Eq ounces #### Tags used in scoring **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: cutoff\_grade is stated **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: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
