Summary
Thunder Mountain Gold, Inc. has announced an updated NI 43-101 Mineral Resource Estimate for its South Mountain Project in Idaho, effective October 16, 2023. The update shows a 7.7% increase in Measured & Indicated tonnage and a 15.1% increase in Inferred tonnage, incorporating new drilling results from 2021. The resource maintains high-grade mineralization across multiple commodities, with detailed assumptions for metallurgical recoveries and an underground mining cut-off grade.
Reasoning: Thunder Mountain Gold has reported a significant update to its South Mountain Mineral Resource Estimate, showing a 7.7% increase in Measured & Indicated tonnage and a 15.1% increase in Inferred tonnage, with corresponding increases in contained metal for zinc, silver, gold, and copper. The estimate is NI 43-101 compliant and includes detailed metallurgical and economic assumptions.

Facts used in scoring: 54
Classification and evidence
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The updated 43-101 MRE was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects.
Evidence · text
“prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI-43-101")”
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: Mr. Richard A. Schwering, SME-RM, P.G., of Hard Rock Consulting, LLC. is identified as the Qualified Person for the estimate.
Evidence · text
“The QP for the estimate Mr. Richard A. Schwering, SME-RM, P.G., of Hard Rock Consulting, LLC. is independent of South Mountain Mining, LLC.”
Category Upgradepositive
Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.
Why it applies: The Measured & Indicated tonnage increased by 7.7% from the previous estimate.
Evidence · text
“7.7% increase to the Measured & Indicated tonnage”
Tonnage Growthpositive
Significant tonnage increase (≥15%) vs prior estimate with grade maintained or improved.
Why it applies: The Inferred tonnage increased by 15.1% from the previous estimate.
Evidence · text
“15.1% increase in the Inferred tonnage”
Contained Metal Growthpositive
True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.
Why it applies: The update includes a significant increase in contained zinc, silver, gold, and copper.
Evidence · text
“significant increase in zinc, silver, gold, and copper.”
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: The document reports an 'Updated 43-101 Mineral Resource Estimate'.
Evidence · text
“Updated 43-101 Mineral Resource Estimate”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: The mineral resource is reported at an underground mining cut-off of $97.50 U.S. Net Smelter Return ('NSR').
Evidence · text
“The mineral resource is reported at an underground mining cut-off of $97.50 U.S. Net Smelter Return ("NSR")”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: A substantial portion of the resource, 959,000 tons, is classified as Inferred.

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.
