Analysis by Minestarters Atlas

Minestarters Atlas analysis

Summary

Vanstar has filed a technical report for the Nelligan Project in Quebec, providing an updated Mineral Resource Estimate as of February 10, 2023. The update, prepared by SRK Consulting, reflects amendments to mining costs and payable metal percentages, resulting in increased tonnage and contained gold for both Indicated and Inferred categories despite slight grade decreases.

Reasoning: The update shows tonnage and contained metal growth due to parameter amendments, though average grades for both Indicated and Inferred categories have slightly declined compared to the January 12, 2023 estimate.

Positive factors

  • Contained metal growth
  • Tonnage growth
  • NI 43-101 compliant
  • QP/CP signed

Negative factors

  • Grade decline

Facts used in scoring: 2

Classification and evidence

NI 43-101 Compliantpositive

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

Why it applies: The report was prepared by SRK Consulting in accordance with NI 43-101 standards.

Evidence · text

“prepared by SRK Consulting (Canada) Inc. ("SRK") in accordance with National Instrument 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: Multiple Qualified Persons (QPs) are named and have reviewed/approved the technical information.

Evidence · text

“Mr. Prakash is an independent "qualified person", as defined by NI 43-101 (a "QP")”

Tonnage Growthpositive

Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

Why it applies: Indicated tonnage increased from 72.2 Mt to 73.5 Mt and Inferred from 114.1 Mt to 129.5 Mt.

Evidence · text

“The changes resulted to a 21,000 ounce increase in estimated Indicated Mineral Resources and 362,000 ounce increase to Inferred Mineral Resources.”

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: Indicated grade decreased from 0.85 to 0.84 g/t Au and Inferred from 0.88 to 0.87 g/t Au.

Evidence · table

“0.84”

Why it applies: category is "indicated"

Cut-off Disclosedpositive

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: cutoff_grade is 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

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.
