The company also announced an accelerated timeline for its maiden mineral resource estimate, now targeted for September 2026. Reasoning: The metallurgical results show exceptionally high recoveries \(95% Au, 92% Ag, 85% Cu\) using standard methods, significantly de-risking the project's processing economics. - Positive factor: High recovery rates across multiple commodities - Positive factor: Strong gravity response for gold - Positive factor: High-purity tungsten concentrate potential - Positive factor: Use of conventional processing methods - Positive factor: QA/QC disclosed with accredited lab Facts used in scoring: 5 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Gold recovery of 95% and 96% exceeds the exceptional band. Evidence · text > 95% Gold **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: Release mentions ALS laboratory, ISO/IEC 17025 accreditation, and QP sign-off. Evidence · text > conforms to the requirements of ISO/IEC 17025 **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Uses conventional gravity, flotation, and cyanidation. Evidence · text > conventional gravity concentration, flotation and cyanidation methods ## Extracted facts Stored fact records: 5.

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.
