Why it applies: no cutoff_grade was stated

JORC Compliantpositive

Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.

Why it applies: reporting_standards includes jorc

No Contained Metalnegative

Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained_metal was not reported

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: no Qualified or Competent Person is named anywhere in the release

Stale Estimatenegative

Context: 2.0

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 Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff_grade was stated

JORC Compliantpositive

Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.

Why it applies: reporting_standards includes jorc

No Contained Metalnegative

Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained_metal was not reported

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: no Qualified or Competent Person is named anywhere in the release

Stale Estimatenegative

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

Why it applies: effective date is 2.2 years before this release

Context: 3.5

Tags used in scoring

Inferred Resourcenegative

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

Why it applies: category is "inferred"

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff_grade was stated

JORC Compliantpositive

Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.

Why it applies: reporting_standards includes jorc

No Contained Metalnegative

Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained_metal was not reported

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: no Qualified or Competent Person is named anywhere in the release

Stale Estimatenegative

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

Why it applies: effective date is 2.2 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.
