Summary
American Tungsten Corp. has filed a NI 43-101 Technical Report for its IMA Project in Idaho. The report details an updated Mineral Resource Estimate including 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 transparency and updates the resource/reserve status for the IMA Project.
Positive factors
- Updated NI 43-101 technical report filed
- Significant inferred resource component established
Negative factors
- High proportion of inferred resource (approx 87%)
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 43-101 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”

“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

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.
