## Minestarters Atlas summary

Hemlo Mining Corp. announced an updated Mineral Resource Estimate for its Hemlo Gold Mine, reporting a significant 34% increase in Measured & Indicated gold resources to 4.8 million ounces and a 39% increase in Inferred resources to 0.9 million ounces. 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 plans further drilling to support a comprehensive resource and reserve update in late 2027.

Reasoning: The updated Mineral Resource Estimate for the Hemlo Gold Mine demonstrates substantial growth in both Measured & Indicated and Inferred gold ounces, reflecting successful drilling, geological reinterpretation, and the identification of new mineralized zones. While some growth is attributed to updated economic assumptions and lower cut-off grades, the overall increase and high confidence in the M&I category are positive indicators for the mine's future.

- Positive factor: Significant increase in M&I and Inferred gold ounces \(1.2 Moz M&I, 0.24 Moz Inferred\).

- Positive factor: Incorporation of additional drilling data and geological reinterpretation.

- Positive factor: Identification of new A-Zone with exploration potential.

- Positive factor: High M&I percentage \(88.9%\) indicates strong geological confidence.

- Positive factor: NI 43-101 compliant and QP signed off.

- Positive factor: Cut-off grades and economic assumptions are clearly disclosed.

- Negative factor: Resource growth partially driven by higher gold price assumption \(US$2,500/oz vs US$1,900/oz previously\) and lower cut-off grades.

Facts used in scoring: 27

## Classification and evidence

**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: M&I Mineral Resources increased by 1.2 Moz, or +34%, compared to the 2025 Report, and Inferred Mineral Resources increased by 242,000 oz, or +39%.

Evidence · text

> represents an increase of 1.2 Moz, or +34%, compared to the 2025 Report. Underground: 24.9 Mt at 3.53 g/t Au for 2.8 Moz \(+40% vs. 2025 Report\) Open Pit: 71.9 Mt at 0.87 g/t Au for 2.0 Moz \(+25% vs. 2025 Report\) 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.

**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: Mr. Brian Hartman \(P. Geo.\) of SLR Consulting \(Canada\) Ltd. is named as the Qualified Person responsible for the Mineral Resource Estimate.

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 CIM Standards and Mr. Hartman is an Independent Qualified Person within the meaning of 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. The MRE was prepared under supervision of Brian Hartman, M.Sc., P.Geo., Principal Resource Geologist at SLR Consulting \(Canada\) Ltd. Mr. Hartman is an Independent Qualified Person within the meaning of NI 43-101 \(as defined herein\).

**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 explicitly states the gold cut-off grades for both Open Pit \(0.28 g/t\) and Underground \(1.8 g/t\) 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.

**Resource Update**

Polarity: neutral

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

Why it applies: The announcement explicitly states it is an 'updated Mineral Resource Estimate' for the Hemlo Gold Mine.

Evidence · text

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

**Cut-off Lowered**

Polarity: negative

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

Why it applies: The resource growth is partly attributed to the 'application of lower cut-off grades' and the sensitivity table shows lower cut-offs for the current $2500/oz gold price compared to the previous $1900/oz gold price.

Evidence · text

> These results reflect the success of recent drilling, enhanced geological reinterpretation, and the application of lower cut-off grades, which have defined larger, more continuous mining areas.

**Inferred Resource**

Polarity: negative

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

Why it applies: The MRE includes a significant Inferred Mineral Resource component of 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

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: The MRE is intended to 'extend mine life, optimize mining operations, and enhance long-term shareholder value' and will form the foundation of a comprehensive update targeted for the second half of 2027, supporting 'future mine planning'.

Evidence · text

> The MRE advances the Company's multi-year strategy to expand Mineral Resources and Mineral Reserves \("MRMR"\), extend mine life, optimize mining operations, and enhance long-term shareholder value.

**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 MRE includes a Measured Mineral Resource component, with 7.18 Mt at 3.60 g/t Au for 832 koz Au \(Total Measured\).

Evidence · table

> 7,180

Context: Total Underground

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: The MRE includes a significant Indicated Mineral Resource component, with 89.686 Mt at 1.39 g/t Au for 4,009 koz Au \(Total Indicated\).

## 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.
