Summary

Serabi Gold has announced updated Mineral Reserve and Resource estimates for its Palito Complex and Coringa Mine, effective January 31, 2026. The company reported a significant 55% increase in Proven and Probable Reserves at the Palito Complex to 228.4 koz Au. Consolidated Measured and Indicated Resources increased by 29% to 730.8 koz Au, while Consolidated Inferred Resources grew by 50% to 653.3 koz Au, primarily driven by strong growth at the Coringa Mine. The estimates were prepared in accordance with NI 43-101 standards and signed off by Qualified Persons.

Reasoning: Serabi Gold has reported a highly positive update to its Mineral Reserves and Resources, with substantial increases in both categories across its key projects, particularly driven by successful brownfield exploration at Coringa. The growth in Measured and Indicated resources significantly de-risks the projects and supports future development.

Positive factors

  • Significant increase in Proven and Probable Reserves at Palito Complex, demonstrating successful resource replenishment.
  • Substantial 29% increase in Consolidated Measured and Indicated Resources, enhancing geological confidence and project viability.
  • Large 50% increase in Consolidated Inferred Resources, indicating strong exploration potential.
  • Exceptional resource growth at Coringa Mine, a new mine with greater geological continuity.
  • All estimates are NI 43-101 compliant and signed off by Qualified Persons, ensuring high reporting standards.

Negative factors

  • São Chico Mine estimates remain unchanged since 2023, indicating no new data or updates for this specific asset.

Reasoning: The Palito Mine Inferred Resource shows tonnage growth but a decrease in grade and contained metal, suggesting some dilution or re-evaluation of lower-grade material.

Positive factors

  • Increase in Inferred Resource tonnage.

Negative factors

  • Decrease in grade and contained metal compared to prior estimate.
  • Inferred category has lower geological confidence.

Evidence · table

“6.5”

Context: 744

Inferred Resourcenegative

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

Why it applies: category is "inferred"

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.

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

Why it applies: reporting_standards includes ni_43_101

Grade Declinenegative

Average grade fell below the red-flag bound vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling.

Why it applies: 6.5 against 7.4 previously

Contained Metal Declinenegative

Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.

Why it applies: 157 against 162 previously

Dilutive Growthnegative

Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion.

Why it applies: tonnage rose while contained metal went 157 from 162

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.
