Summary

Thesis Gold has filed its 2025 Pre-Feasibility Study (PFS) for the Lawyers-Ranch gold-silver project in British Columbia. The study reports a maiden mineral reserve of 76.16 million tonnes at 0.97 g/t Au and 28 g/t Ag, featuring strong economics with a 54.4% after-tax IRR and an NPV5% of $2.37 billion.

Reasoning: The filing of a Pre-Feasibility Study (PFS) that establishes a maiden mineral reserve with robust economics is a major project de-risking milestone.

Positive factors

  • Strong economics with 54.4% after-tax IRR
  • Maiden Mineral Reserve statement established
  • Low AISC of US$1,185 per AuEq ounce
  • Significant silver revenue contribution (23%)

Facts used in scoring: 2

Classification and evidence

Probable Reservepositive

Indicated Resource with demonstrated economic viability after applying modifying factors.

Why it applies: The document reports a maiden mineral reserve statement.

Evidence · text

“Mineral Reserve: Maiden Mineral Reserve statement with 76.16 million tonnes”

Maiden Resourceneutral

First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable.

Why it applies: The report establishes the first formal mineral reserve for the project.

Evidence · text

“Maiden Mineral Reserve statement”

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: Michael Dufresne, P.Geo., is named as the Qualified Person who reviewed and approved the content.

Evidence · text

“reviewed and approved by Michael Dufresne, M.Sc, P.Geol., P.Geo., a non-independent Qualified Person”

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.
