Summary
Gold Terra Resource Corp. announced an updated Mineral Resource Estimate for its Yellowknife Project, adding 595,000 inferred gold ounces at 3.64 g/t Au for the Zone 103N deposit. The 2026 MRE also includes updates for the Yellorex and Crestaurum deposits, resulting in a total inferred resource of 7.53 million tonnes at 3.69 g/t Au for 895,000 ounces and an indicated resource of 729,000 tonnes at 4.39 g/t Au for 103,000 ounces across all updated deposits. The estimate, prepared by SLR Consulting, is NI 43-101 compliant, with further updates planned for Q4 2026 and a PEA anticipated by year-end.
Reasoning: Gold Terra announced an updated Mineral Resource Estimate for its Yellowknife Project, adding 595,000 inferred gold ounces at Zone 103N and updating other deposits. The MRE is NI 43-101 compliant and signed off by Qualified Persons, but a significant portion remains in the inferred category, and classification criteria were more conservative.
Positive factors
- Significant increase in inferred ounces with first-time MRE for Zone 103N
- Updated resource estimates for Yellorex and Crestaurum
- NI 43-101 compliant and QP signed off
- High gold grades for several deposits
Negative factors
- High proportion of inferred resources in the updated estimate
- Conservative classification criteria reducing drill spacing for classification compared to prior MREs
- Historical nature of Zone 103N drilling limited classification to Inferred despite tight spacing
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 16
Classification and evidence
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: A current resource fact retains the disclosed cut-off grade

Reasoning: This is the first-time disclosure of an inferred resource for Zone 103N, adding significant ounces at a strong underground grade, indicating high novelty and materiality despite the inferred classification.
Positive factors
- First-time MRE for Zone 103N
- Strong gold grade for underground deposit
- Significant contained metal (595 koz)
Negative factors
- Resource is entirely in the inferred category
- Conservative classification criteria applied

Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: category is "inferred"
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
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
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: effective date is 5.2 years before this release

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.
