## Minestarters Atlas summary

Hemlo Mining Corp. announced an updated Mineral Resource Estimate for its Hemlo Gold Mine in Marathon, Ontario, reporting a significant increase in gold resources. Measured &amp; Indicated resources grew by 34% to 4.8 Moz Au, and Inferred resources increased by 39% to 0.9 Moz Au. The growth is attributed to additional drilling, geological reinterpretation, and updated economic assumptions, including a higher gold price and lower cut-off grades.

Reasoning: The updated Mineral Resource Estimate for the Hemlo Gold Mine shows a significant increase in both Measured &amp; Indicated and Inferred gold resources, driven by additional drilling, geological reinterpretation, and updated economic assumptions including a higher gold price and lower cut-off grades. The identification of a new A-Zone also contributes to the growth.

- Positive factor: Tonnage Growth

- Positive factor: Contained Metal Growth

- Positive factor: Category Upgrade

- Positive factor: QP/CP Signed

- Positive factor: NI 43-101 Compliant

- Positive factor: New Zone Identified

- Negative factor: Cut-off Lowered

- Negative factor: Gold Price Increase

Low confidence — this extraction should be reviewed alongside the original source.

## Classification and evidence

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: The MRE reports a significant increase in total Measured &amp; Indicated resources to 96.9 Mt and Inferred resources to 12.1 Mt.

Evidence · text

> Measured &amp; Indicated \("M&amp;I"\) 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.

**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 MRE shows an increase of 1.2 Moz in M&amp;I gold resources \(+34%\) and 0.242 Moz in Inferred gold resources \(+39%\) compared to the prior estimate.

Evidence · text

> Measured &amp; Indicated \("M&amp;I"\) Mineral Resources \(100% basis\) of ... 4.8 million ounces \("Moz"\) of gold \("Au"\); 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 news release explicitly states that Dr. Raphael Dutaut and Mr. Brian Hartman, both P.Geo., are Qualified Persons responsible for reviewing and approving the scientific and technical information and the MRE.

Evidence · text

> 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 – Standards of Disclosure for Mineral Projects \("NI 43-101"\). Mr. Brian Hartman, P.Geo., of SLR Consulting \(Canada\) Ltd., Denver, Colorado, is an independent Qualified Person for the mineral resource estimate disclosed herein, as defined by NI 43-101, and has reviewed and approved the relevant contents of this news release.

**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, and a Qualified Person under NI 43-101 has signed off on the estimate.

Evidence · text

> Mr. Hartman is an Independent Qualified Person within the meaning of NI 43-101 \(as defined herein\). 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.

**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 document clearly states the cut-off grades used for both Open Pit \(0.28 g/t Au\) and Underground \(1.8 g/t Au\) resources.

Evidence · text

> Open Pit Mineral Resources are reported using a gold cut-off grade of 0.28 g/t. Underground Mineral Resources are reported on a diluted basis using a gold cut-off grade of 1.8 g/t.

**Cut-off Lowered**

Polarity: negative

Definition: Cut-off grade significantly reduced vs prior estimate — tonnage growth may be artificial inflation.

Why it applies: The MRE's increases are partly related to updated economic assumptions, including a higher gold price which led to lower cut-off grades \(from 0.36 g/t Au to 0.28 g/t Au for Open Pit and 2.4 g/t Au to 1.8 g/t Au for Underground\).

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 \(see Table 4 for sensitivity analysis\)

**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: A portion of the resource growth is attributed to updated economic assumptions, including a higher gold price and lower cut-off grades, which can incorporate lower-grade material into the resource.

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 \(see Table 4 for sensitivity analysis\)

**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 new drilling and revised assumptions.

Evidence · text

> Hemlo Mining Corp. Announces Increased Mineral Resource Estimate for the Hemlo Gold Mine

**Inferred Resource**

#### 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

**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: 793 against 540 previously

**Cut-off Lowered**

Polarity: negative

Definition: Cut-off grade significantly reduced vs prior estimate — tonnage growth may be artificial inflation.

Why it applies: 1.8 against 2.4 previously

**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.
