Reasoning: Historical inferred resource restatement.
Evidence · text
“Inferred mineral resource of 20.5 million ounces of silver equivalent (“AgEq”) (19.0 million ounces of silver (“Ag”) and 19.2 thousand ounces of gold (“Au”)) from 3.41 million tonnes at 187 g/t Ag Eq (173 g/t Ag and 0.18 g/t Au)”
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
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: effective date is 2.6 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.
