## Minestarters Atlas summary

American Tungsten Corp. announced a maiden NI 43-101 compliant Mineral Resource Estimate for its IMA Mine in Idaho, U.S., with an effective date of July 15, 2026. The MRE defines 316,000 tonnes of Indicated Resources at 0.55% WO₃ and 2,178,000 tonnes of Inferred Resources at 0.55% WO₃, along with significant silver, molybdenum, copper, and lead byproducts. An additional 267,000 tonnes of Indicated Resources at 0.155% WO₃ are contained in historical surface tailings, providing a potential lower-capital pathway to production.

Reasoning: American Tungsten announced a maiden NI 43-101 compliant Mineral Resource Estimate for its IMA Mine, defining high-grade tungsten and silver resources with significant growth potential. While the estimate is a key milestone and supports future economic studies, a large portion of the resource is in the Inferred category, and the extralateral rights supporting part of the resource are subject to challenge.

- Positive factor: high\_grade\_resource

- Positive factor: ni\_43\_101\_compliant

- Positive factor: qp\_signed

- Positive factor: growth\_potential

- Positive factor: critical\_mineral\_focus

- Positive factor: existing\_infrastructure

- Positive factor: pea\_supporting

- Negative factor: large\_inferred\_component

- Negative factor: extralateral\_rights\_risk

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

- Rubric flag: M&I \(Measured + Indicated\) confidence tiers — The M&I percentage for the IMA Tungsten Vein System \(12.67%\) is weak \(<25% M&I\), indicating a high proportion of inferred resources.

- Rubric flag: Contained metal scale by commodity — The total contained tungsten \(13,680 tonnes WO₃\) and silver \(2.25 Moz Ag\) are below the weak thresholds for comparable commodities, indicating a relatively small scale.

Facts used in scoring: 24

## Classification and evidence

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The Mineral Resource Estimate was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects.

Evidence · text

> The MRE has an effective date of July 15, 2026 and was prepared by Minetech, LLC, in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects\("NI 43-101"\)

**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 estimates were prepared by Karl Swanson, SME-RM and AusIMM, an independent Qualified Person, and reviewed and approved by Austin Zinsser, P.G., SME-RM, a Qualified Person.

Evidence · text

> The Mineral Resource estimates were prepared by Karl Swanson, SME-RM and AusIMM, of Minetech, LLC,an independent Qualified Person for the purposes of NI 43-101. Technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in NI 43-101. Austin Zinsser, P.G., SME-RM, Vice President, Exploration for the Company, and a Qualified Person as defined by NI 43-101, has reviewed and approved the scientific and technical information in this news release.

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: This announcement defines the first Mineral Resource Estimate for the IMA Mine by American Tungsten.

Evidence · text

> American Tungsten Defines High-Grade Tungsten Mineral Resource in the United States at IMA Mine

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The MRE provides the technical foundation for advancing future resource and economic studies, including a Preliminary Economic Assessment.

Evidence · text

> The MRE provides the technical foundation for advancing future resource and economic studies, including a Preliminary Economic Assessment \("PEA"\).

**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 cut-off grades for both the tungsten vein system \(0.20% WO₃\) and historical tailings \(0.0% WO₃ reported, 0.07% WO₃ effective\) are clearly stated.

Evidence · text

> The underground tungsten vein system is reported at a cut-off grade of 0.20% WO₃... The effective cut-off grade for the IMA Historical Tailings is estimated at 0.07% WO₃... Tailings mineral resources are reported at 0.0% cut-off.

**Inferred Resource**

Polarity: negative

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

Why it applies: A significant portion of the resource, 2,178,000 tonnes, is classified as Inferred Mineral Resources.

Evidence · text

> 2,178,000 tonnes of Inferred Mineral Resources grading 0.55% WO₃

**Extralateral Rights Risk**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The Mineral Resource Estimate includes vein systems that rely on extralateral rights, which have not been adjudicated and may be subject to challenge.

Evidence · text

> While the Company believes its position of extralateral rights is well-supported by both the US mining law and the project geology and mineralization, such rights have not been adjudicated and may be subject to challenge by adjacent claim holders.

## 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.
