The company is preparing for underground delineation drilling in early 2026 and continues to optimize metallurgical processes. Reasoning: The company reported high-grade surface and underground sampling results and strong preliminary gold recoveries \(avg 95%\), though silver recovery remains variable and unoptimized. - Positive factor: high-grade epithermal system confirmed - Positive factor: strong gold recoveries in preliminary metallurgy - Positive factor: QA/QC protocols and QP sign-off disclosed - Negative factor: variable and lower silver recoveries - Negative factor: preliminary/unoptimized metallurgical testwork Facts used in scoring: 16 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions NI 43-101 compliance, use of certified reference materials, blanks, and an ISO 17025 accredited lab \(SGS\). Evidence · text > The lab is accredited to ISO/IEC 17025:2017. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Underground channel samples grading up to 50.3 g/t Au and 269 g/t Ag. Evidence · table > 50.3 Context: 1.7 **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Metallurgical results are from preliminary bottle roll and gravity tests without optimization. Evidence · text > Given that these were preliminary tests, there was no optimization ## Extracted facts Stored fact records: 16.

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.
