The program identified several high-grade intercepts, including 20 ft at 0.70% TCu in Trench 1, with mineralization appearing to be open in multiple directions. Reasoning: Positive surface trenching results at a new prospect \(Mason Pass\) showing ore-grade copper oxide mineralization, supported by robust QA/QC disclosure. - Positive factor: At-surface ore-grade copper oxide mineralization encountered - Positive factor: Mineralization remains open and untested in most directions - Positive factor: QA/QC protocols \(standards, blanks, chain of custody\) clearly disclosed - Positive factor: QP sign-off provided Facts used in scoring: 8 ## 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 includes details on standards, blanks, and chain of custody. Evidence · text > Commercially prepared standards and blanks were inserted by the Company at 50-ft intervals **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: New mineralization identified at Mason Pass prospect near existing MacArthur pit. Evidence · text > The Mason Pass prospect is an at-surface copper oxide target located approximately 1.5 miles south-southwest of the MacArthur pit ## Extracted facts Stored fact records: 8.

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.
