The results confirm mineralization within the pile, with a best sub-interval of 2.34 g/t Au and 68 g/t Ag, and will support upcoming metallurgical testing. Reasoning: The aircore program successfully characterized the waste rock pile, confirming mineralization and providing material for upcoming metallurgical testing. - Positive factor: Confirms mineralization in historic waste rock pile - Positive factor: QA/QC disclosed with certified lab and QP sign-off - Positive factor: High-grade sub-interval reported \(2.34 g/t Au, 68 g/t Ag\) - Negative factor: Finite project scale \(waste rock pile is a limited resource\) Facts used in scoring: 6 ## 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 insertion of blanks, duplicates, and certified reference materials, and names an independent certified laboratory. Evidence · text > QA/QC procedures included the insertion of blanks, duplicates, and certified reference materials. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The 2.34 g/t Au sub-interval in PM25-001S is significantly higher than the program average. Evidence · text > A best assay of 2.34 g/t Au, 68 g/t Ag was reported in hole PM25-001S from 0-5ft **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("column leach"\) ## Extracted facts Stored fact records: 6.

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.
