Summary

American Tungsten has filed a NI 43-101 Technical Report for the IMA Project in Idaho, detailing updated mineral resource and reserve estimates. The project includes 316,000 tonnes of Indicated and 2,178,000 tonnes of Inferred tungsten resources, alongside a surface tailings resource.

Reasoning: The filing of a formal NI 43-101 technical report provides regulatory de-risking and formalizes the existing resource estimate for the IMA Project.

Positive factors

  • Significant inferred resource tonnage
  • Clear phased development strategy (tailings then underground)
  • NI 43-101 compliant technical report filed

Negative factors

  • Large portion of resource is Inferred
  • Tailings resource grade is significantly lower than main body

Facts used in scoring: 3

Classification and evidence

NI 43-101 Compliantpositive

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

Why it applies: The company filed a National Instrument 43-10 Technical Report.

Evidence · text

“announced today the Company has filed a National Instrument 43-10 Technical Report”

Inferred Resourcenegative

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

Why it applies: A significant portion of the resource is in the Inferred category.

Evidence · text

“2,178,000 tonnes of Inferred Mineral Resources”

Reasoning: Standard indicated resource component of the updated estimate.

Positive factors

  • Indicated category provides reasonable geological confidence

Evidence · text

“316,000 tonnes of Indicated Mineral Resources grading 0.55% WO3, containing 1,747 tonnes of WO3”

Tags used in scoring

Indicated Resourcepositive

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

Why it applies: category is "indicated"

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff_grade was stated

QP/CP Signedpositive

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 Compliantpositive

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

Why it applies: reporting_standards includes ni_43_101

PEA-Supportingneutral

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

Why it applies: the release names the study this estimate supports

Reasoning: Large volume of resource but limited geological confidence.

Positive factors

  • Large tonnage scale

Negative factors

  • Inferred category is speculative

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.
