The tests confirmed the gold is free-milling and contains coarse gold, suggesting potential for lower CAPEX and OPEX through coarse grinding and gravity pretreatment. Reasoning: The results demonstrate exceptionally high gold recoveries \(up to 100% via optimized flowsheet\) and confirm the ore is free-milling with significant gravity-recoverable gold, which is highly positive for project economics. - Positive factor: High gold recoveries \(up to 100%\) - Positive factor: Free-milling gold identified - Positive factor: Coarse gold presence allows for gravity pretreatment - Positive factor: Conventional flowsheet options \(gravity, flotation, tank leach\) demonstrated - Positive factor: Coarse grind potential reduces CAPEX/OPEX - Negative factor: Testing performed on indicative composites rather than a formal MRE Facts used in scoring: 10 ## Classification and evidence **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation.

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.
