The results, conducted by Alfred H Knight, confirm that the mineralization responds well to a conventional gravity-cyanidation flowsheet. Reasoning: The testwork demonstrates strong gold recoveries \(89.6-90.8%\) using a conventional gravity-cyanidation circuit, supporting the project's PEA advancement. - Positive factor: High overall gold recoveries \(90% range\) - Positive factor: Fast leach kinetics - Positive factor: Conventional flowsheet compatibility - Positive factor: QA/QC disclosed with accredited lab - Negative factor: Interim results only - Negative factor: Requires further optimization for reagent consumption Facts used in scoring: 6 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The testwork involves milling to 80% passing 75 microns and cyanide leaching. Evidence · text > A 20-kilogram sample was milled to 80% passing 75 microns **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: The flowsheet includes a Falcon L40 centrifugal gravity concentrator. Evidence · text > processed through a Falcon L40 centrifugal gravity concentrator **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release mentions ISO 17025 accreditation for the assay lab and digital sample tracking. Evidence · text > SAEL Assay Laboratory, which is ISO 17025 accredited **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

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.
