This growth is attributed to additional drilling, geological reinterpretation, and updated economic assumptions, including a higher gold price and lower cut-off grades. The company is undertaking a 130,000-meter drill program to further expand and convert resources, with a comprehensive update targeted for late 2027. Reasoning: Hemlo Mining Corp. announced a substantial increase in both M&I and Inferred gold resources at its Hemlo Gold Mine, driven by additional drilling, geological reinterpretation, and updated economic assumptions. The M&I resource now stands at 4.8 Moz Au, representing a 34% increase, while Inferred resources grew by 39% to 0.9 Moz Au. The update highlights the project's significant growth potential and is supported by ongoing exploration and conversion drilling, although some growth is attributed to higher gold price assumptions and lower cut-off grades. - Positive factor: Significant increase in Measured & Indicated \(M&I\) contained gold ounces \(+34%\) - Positive factor: Significant increase in Inferred contained gold ounces \(+39%\) - Positive factor: High confidence in M&I resource \(96.9 Mt at 1.55 g/t Au for 4.8 Moz Au\) - Positive factor: Resource estimate prepared to NI 43-101 standards and signed off by Qualified Persons - Positive factor: Ongoing 130,000-meter drill program targeting resource conversion and expansion - Positive factor: Identification of new mineralized zones \(A-Zone\) and extensions \(E-Zone, B-Zone Deep, South Rim Zone\) - Negative factor: Increase in resource partially driven by higher gold price assumption \($2,500/oz vs $1,900/oz previously\) - Negative factor: Increase in resource partially driven by application of lower cut-off grades - Negative factor: Open Pit Inferred contained metal decreased by 17% compared to the prior estimate Facts used in scoring: 14 ## Classification and evidence **Measured Resource** Polarity: positive Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves. Why it applies: The resource estimate includes a Measured category, which is the highest confidence category for mineral resources. Evidence · text > Measured & Indicated \("M&I"\) Mineral Resources \(100% basis\) of 96.9 million tonnes \("Mt"\) at 1.55 grams per tonne \("g/t"\) Au for 4.8 million ounces \("Moz"\) of gold \("Au"\) **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The resource estimate includes a significant Indicated category, which provides reasonable geological confidence. Evidence · text > Measured & Indicated \("M&I"\) Mineral Resources \(100% basis\) of 96.9 million tonnes \("Mt"\) at 1.55 grams per tonne \("g/t"\) Au for 4.8 million ounces \("Moz"\) of gold \("Au"\) **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 Measured & Indicated contained gold ounces increased by 34% \(1.2 Moz\) and Inferred contained gold ounces increased by 39% \(0.24 Moz\) compared to the 2025 Report. Evidence · text > represents an increase of 1.2 Moz, or +34%, compared to the 2025 Report. **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 mineral resource estimate was prepared under the supervision of Mr. Brian Hartman \(P. Geo.\) and reviewed by Dr. Raphael Dutaut, both Qualified Persons as defined by NI 43-101. Evidence · text > The qualified person \("QP"\) responsible for this Mineral Resource Estimate is Mr. Brian Hartman \(P. Geo.\) of SLR Consulting \(Canada\) Ltd. **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 was prepared in accordance with NI 43-101 standards. Evidence · text > The MRE was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum \("CIM"\) Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The estimate includes a significant Inferred resource component, which is a speculative category with lower geological confidence. Evidence · text > Inferred Mineral Resources \(100% basis\) of 12.1 Mt at 2.22 g/t Au for 0.9 Moz Au **Cut-off Lowered** Polarity: negative Definition: Cut-off grade reduced beyond the suspicious bound vs prior estimate — tonnage growth may be artificial inflation. Why it applies: The resource increase is partly due to the application of lower cut-off grades, which can inflate tonnage at the expense of grade. Evidence · text > application of lower cut-off grades, which have defined larger, more continuous mining areas. **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: This document announces an updated Mineral Resource Estimate for an existing mine. Evidence · text > Hemlo Mining Corp. Announces Increased Mineral Resource Estimate for the Hemlo Gold Mine **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The MRE is a milestone towards a comprehensive MRMR update and Technical Report targeted for the second half of 2027, which typically supports feasibility studies. Evidence · text > The MRE represents an important milestone toward a comprehensive MRMR update and Technical Report targeted for the second half of 2027. ## Extracted facts Stored fact records: 14.

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.
