## Minestarters Atlas summary

Hemlo Mining Corp. announced an updated Mineral Resource Estimate for its Hemlo Gold Mine in Marathon, Ontario, showing a significant increase in both Measured & Indicated \(M&I\) and Inferred gold resources. M&I resources grew by 34% to 4.8 million ounces, and Inferred resources increased by 39% to 0.9 million ounces. The update incorporates additional drilling, geological reinterpretation, and higher gold price assumptions, with a new A-Zone contributing to the Inferred category.

Reasoning: Hemlo Mining Corp. announced a substantial increase in its M&I and Inferred gold resources at the Hemlo Gold Mine, driven by new drilling, geological reinterpretation, and updated economic assumptions. The MRE is NI 43-101 compliant and signed off by Qualified Persons, indicating high confidence. While lower cut-off grades contributed to the increase, the overall growth and identification of new zones are positive for the project's future.

- Positive factor: Significant increase in Measured & Indicated \(M&I\) and Inferred Mineral Resources

- Positive factor: QP/CP signed off on the estimate, ensuring compliance with NI 43-101 standards

- Positive factor: Identification of new mineralized zones \(A-Zone\) and extensions to existing ones

- Positive factor: Ongoing 130,000-meter drill program aimed at further resource growth and conversion

- Negative factor: Tonnage growth partially attributed to lower cut-off grades and higher gold price assumptions

- Negative factor: Open Pit Inferred resources decreased by 17% compared to the prior estimate

Facts used in scoring: 21

## Classification and evidence

**Tonnage Growth**

Polarity: positive

Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

Why it applies: The Measured & Indicated Mineral Resources increased by 34% and Inferred Mineral Resources increased by 39% compared to the 2025 Report.

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 \("Au"\); represents an increase of 1.2 Moz, or +34%, compared to the 2025 Report. ... Inferred Mineral Resources \(100% basis\) of 12.1 Mt at 2.22 g/t Au for 0.9 Moz Au; represents an increase of 242,000 oz, or +39%, compared to the 2025 Report.

**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 increased by 1.2 Moz \(+34%\) and Inferred contained gold increased by 0.242 Moz \(+39%\) 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 has been reviewed and approved by Mr. Brian Hartman \(P. Geo.\) of SLR Consulting \(Canada\) Ltd. and Dr. Raphael Dutaut, Ph.D., P.Geo., Vice President, Exploration of Hemlo Mining Corp., both Qualified Persons.

Evidence · text

> The qualified person \("QP"\) responsible for this Mineral Resource Estimate is Mr. Brian Hartman \(P. Geo.\) of SLR Consulting \(Canada\) Ltd. ... The scientific and technical information in this news release has been reviewed and approved by Dr. Raphael Dutaut, Ph.D., P.Geo., Vice President, Exploration of Hemlo Mining Corp., who is a "Qualified Person" as defined by National Instrument 43-101

**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 the Canadian Institute of Mining, Metallurgy and Petroleum \("CIM"\) Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended, and is compliant with NI 43-101.

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.

**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 for the Hemlo Gold Mine, incorporating additional drilling and updated assumptions since the last estimate.

Evidence · text

> Hemlo Mining Corp. is pleased to announce an updated Mineral Resource Estimate \("MRE"\) for the Hemlo Gold Mine

**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 increase in resources is partly attributed to the application of lower cut-off grades, driven by an increased long-term gold price assumption from US$1,900/oz to US$2,500/oz, which resulted in lower cut-offs \(e.g., Open Pit from 0.36 g/t Au to 0.28 g/t Au, Underground from 2.4 g/t Au to 1.8 g/t Au\).

Evidence · text

> The increases are mostly related to \(i\) the updated economic assumptions, including an increase in the long-term gold price from US$1,900/oz in the 2025 Report to US$2,500/oz in the MRE

**Dilutive Growth**

Polarity: negative

Definition: Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion.

Why it applies: The overall tonnage and contained metal increased, but this was partly due to the application of lower cut-off grades, which can incorporate lower-grade material and dilute the overall resource grade.

Evidence · text

> The increases are mostly related to \(i\) the updated economic assumptions, including an increase in the long-term gold price from US$1,900/oz in the 2025 Report to US$2,500/oz in the MRE

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The document reports a significant portion of the resource in the Inferred category, including 12.1 Mt at 2.22 g/t Au for 0.9 Moz Au.

Evidence · text

> Inferred Mineral Resources \(100% basis\) of 12.1 Mt at 2.22 g/t Au for 0.9 Moz Au

Reasoning: The Total Underground Indicated resource shows good confidence and a good grade for underground operations. The lower cut-off grade, however, suggests some dilutive growth.

- Positive factor: Indicated category provides reasonable geological confidence

- Positive factor: Good grade for underground mining

- Negative factor: Lower cut-off grade \(1.8 g/t Au vs 2.4 g/t Au\) contributed to tonnage increase

Reasoning: The Underground \(ex. Interlake\) Inferred resource offers good exploration potential and a solid grade for underground operations. The lower cut-off grade, however, suggests some dilutive growth.

- Positive factor: Inferred resource provides future exploration potential

- Positive factor: Good grade for underground mining

- Negative factor: Lower cut-off grade \(1.8 g/t Au vs 2.4 g/t Au\) contributed to tonnage increase

#### 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.

**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

**Cut-off Lowered**

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: the release compares against a previous estimate

## 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.
