The oxide mineralization shows high acid solubility \(91%\) and is expected to be evaluated for a new resource estimate and potential economic viability via surface mining. Reasoning: The drill program successfully identified a significant copper oxide cap above the main sulfide deposit, which management believes can be economically extracted via surface mining, potentially improving project economics. - Positive factor: Identification of a near-surface copper oxide cap - Positive factor: High acid soluble copper \(91% of total\) - Positive factor: Potential for low-cost surface mining - Positive factor: Existing NI 43-101 resource and PEA in place - Negative factor: Oxide cap is relatively small compared to the sulfide deposit Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling identified a near-surface oxide cap that was previously considered waste, potentially expanding the economic footprint. Evidence · text > Results confirmed a small oxide cap covers the large Moonlight sulfide deposit. This cap had been considered waste rock by previous operators **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 details specific QA/QC protocols including standards, duplicates, and blanks. Evidence · text > The QAQC elements consist of certified standards, duplicate analyses and certified coarse blanks **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The document references an existing NI 43-101 Technical Report and PEA. Evidence · text > This resource estimate is contained in the NI 43-101 Technical Report and Preliminary Economic Assessment \("PEA"\) ## Extracted facts Stored fact records: 6.
