The estimate, which is entirely in the Inferred category, highlights the project's high-grade profile and significant resource base, with potential for expansion along strike and down-dip. The company plans additional drilling in Q4/2026 to test these expansion areas. Reasoning: The updated Mineral Resource Estimate for Ogama-Rockland reports a substantial Inferred gold resource of 712,000 ounces at a high grade of 6.68 g/t, indicating significant potential for the project with planned drilling to expand the resource, despite the lower confidence associated with the Inferred category. - Positive factor: High-grade - Positive factor: Significant contained metal - Positive factor: Potential for resource expansion - Positive factor: QP sign-off - Positive factor: CIM compliant - Positive factor: Detailed cut-off grade assumptions - Positive factor: Underground mining method implied - Negative factor: Entirely Inferred resource - Negative factor: Uncertainty inherent in Inferred classification Facts used in scoring: 1 ## Classification and evidence **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The entire resource is classified as Inferred, which is the lowest confidence category. Evidence · table > Inferred Resources Context: 3,314,000 **All Inferred** Polarity: negative Definition: 100% of resource is Inferred category — very early stage, no engineering confidence. Why it applies: The resource estimate is comprised solely of Inferred Mineral Resources, indicating a lower level of geological confidence. Evidence · text > The 2026 MRE consists of Inferred Mineral Resources **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 and approved by Tim Maunula, P.Geo., an Independent Qualified Person under NI 43-101 standards. Evidence · text > The 2026 MRE was completed by Tim Maunula, P.Geo. of T. Maunula & Associates Consulting Inc., Chatham, Ontario, Canada, who is an Independent Qualified Person \("QP"\) under NI 43-101 standards. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The cut-off grade of 2.50 g/t Au used for the resource estimate is clearly stated along with its economic assumptions. Evidence · table > 2.50 g/t Au Context: The 2026 MRE uses a cut-off grade of 2.50 g/t Au based on assumptions of a gold price of US$2,500/oz, an exchange rate of US$/C$ 0.72, mining operating costs of C$175.00/t, processing costs of C$38.00/t processed, haulage costs of $15.20/t mined, G&A of C$37.00/t processed and average gold recoverability of 94%. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The MRE follows the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines, which are consistent with NI 43-101 standards. Evidence · table > The 2026 MRE follows the November 29, 2019, CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines. Context: The effective date of the 2026 MRE is August 6, 2026, and is based upon all exploration data available up to April 20, 2026. **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 Mineral Resource Estimate for the project. Evidence · text > 1911 Gold Announces Mineral Resource Estimate Update for the Ogama-Rockland Gold Project **High Recovery** Polarity: positive Story-specific tag Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: The average gold recoverability of 94% used in the economic assumptions for the cut-off grade is high. Evidence · table > average gold recoverability of 94% Context: The 2026 MRE uses a cut-off grade of 2.50 g/t Au based on assumptions of a gold price of US$2,500/oz, an exchange rate of US$/C$ 0.72, mining operating costs of C$175.00/t, processing costs of C$38.00/t processed, haulage costs of $15.20/t mined, G&A of C$37.00/t processed and average gold recoverability of 94%. **High Grade** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: The Inferred resource grade of 6.68 g/t Au is strong for an underground gold project, exceeding the 4 g/t threshold for strong underground gold grades.

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.
