Minestarters Atlas analysis

Summary

Kintavar Exploration Inc. issued a clarification regarding the Roger Project, noting that previously disclosed resource figures are historical estimates under NI 43-101 standards. The company emphasized that these figures have not been verified as current resources and requires additional drilling and studies to upgrade them.

Reasoning: The document is a clarification reissuing historical resource data for the Roger Project to ensure NI 43-101 compliance. While it provides specific tonnage and grade figures, the company explicitly states these are historical, unverified, and not treated as current resources.

Positive factors

  • Historical resource base established

Negative factors

  • Historical estimate status
  • Lack of current verification
  • Reliability unconfirmed

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 6

Classification and evidence

Historical Estimate Onlynegative

Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.

Why it applies: The company clarifies that the Roger Project estimates are historical and not current mineral resources.

Evidence · text

“the estimates provided... did not contain a current mineral resource estimate and such information is provided as a "historical estimate"”

No QP/CP Disclosurenegative

No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.

Why it applies: The company states a qualified person has not done sufficient work to classify these as current resources.

Evidence · text

“A qualified person has not done sufficient work to classify the historical estimates referenced herein as current mineral resources or mineral reserves”

Reasoning: Indicated resource component of a historical estimate.

Negative factors

  • Historical status

Evidence · text

“an Indicated Resource was estimated to be 10,900,000* metric tonnes at a grade of 0.85 g/t of gold”

Tags used in scoring

Indicated Resourcepositive

Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

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

Stale Estimatenegative

Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: effective date is 6.8 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.
