## Minestarters Atlas summary

Lahontan Gold Corp. provided an update on the Santa Fe Mine Project, highlighting the upcoming completion of an updated Mineral Resource Estimate and a revised PEA. The company reported new exploration progress at the Slab West discovery and is conducting drilling to evaluate the reprocessing of historic heap leach pads. Permitting activities for groundwater and waste rock characterization are also advancing toward a planned 2027 construction.

Reasoning: The company is advancing multiple workstreams including a new discovery, upcoming resource/economic updates, and permitting, though technical delays are noted.

- Positive factor: New Slab West discovery remains open

- Positive factor: Updated MRE and PEA expected shortly

- Positive factor: Permitting progress on groundwater and waste rock

- Positive factor: Brownfields restart potential via heap leach reprocessing

- Negative factor: Modest delays in MRE completion due to consultant demand

- Negative factor: Assay results for some RVC holes are delayed

Facts used in scoring: 6

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: New Slab West discovery is described as a previously unrecognized zone west of the Slab resource.

Evidence · text

> discovery of a new, previously unrecognized zone of gold mineralization west of the Slab resource \(“ Slab West “\)

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release names a Qualified Person \(Brian J. Maher\) who has verified the sampling, analytical, and test data.

Evidence · text

> Qualified Person Brian J. Maher... has verified the data disclosed in this news release, including the sampling, ‎‎analytical and test data underlying the disclosure.

**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 an Inferred Mineral Resource component.

Evidence · text

> an Inferred Mineral Resource of 411,000 oz Au Eq

**Indicated Resource**

Polarity: positive

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

Why it applies: The document reports an Indicated Mineral Resource component.

Evidence · text

> an NI 43-101 compliant Indicated Mineral Resource of 1,539,000 oz Au Eq

**Cut-off Disclosed**

Polarity: positive

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

Why it applies: A current resource fact retains the disclosed cut-off grade

## 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.
