## Minestarters Atlas summary

Lahontan Gold has announced an updated Mineral Resource Estimate for the Santa Fe Mine in Nevada, reporting a 22% increase in total gold equivalent ounces. The update includes 1,195,000 oz Au Eq Indicated and 1,190,000 oz Au Eq Inferred, with significant growth noted in the shallow oxide deposits.

Reasoning: The update shows a substantial 22% increase in total gold equivalent ounces, driven by both project-wide growth and specific expansion in the oxide deposits.

- Positive factor: Significant tonnage and contained metal growth \(22% increase\)

- Positive factor: Expansion of shallow oxide resources \(>37%\)

- Positive factor: High-grade sulfide component identified

- Positive factor: QP/CP sign-off provided

- Negative factor: Large portion of resource remains in Inferred category

Facts used in scoring: 12

## Classification and evidence

**Tonnage Growth**

Polarity: positive

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

Why it applies: Total resource ounces increased by 435,000 ounces or 22% over the 2024 MRE.

Evidence · text

> a total increase of 435,000 ounces or 22% over the 2024 MRE

**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: Michael S. Lindholm, C.P.G. and Thomas Dyer, PE are named as independent Qualified Persons.

Evidence · text

> The independent Qualified Persons responsible for the MRE disclosure... are Michael S. Lindholm, C.P.G., and Thomas Dyer, PE

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: Cut-off grades of 0.10 g/t Au Eq for oxide/transitional and 0.30 g/t Au Eq for sulfide are stated.

Evidence · text

> Mineral resources are reported using a cut-off grade of 0.10 g/t Au Eq for oxide and transitional resources... and 0.30 g/t Au Eq for sulfide resources.

**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 is classified in accordance with CIM Standards and a technical report will be filed per NI 43-101.

Evidence · text

> The MRE’s were classified in accordance with the 2014 CIM Definition Standards.

## 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.
