The company has expanded its claim area significantly and plans a 10,000-20,000 metre follow-up program to test regional targets within a larger epithermal system. Reasoning: The release reports successful step-out drilling that extends known high-grade mineralization and defines a larger regional epithermal system, supported by a significant land expansion and strong cash position. - Positive factor: Step-out drilling successfully extended mineralization at Basalto Zone and Manchuria Hill Eastern Zone - Positive factor: High-grade intercepts reported in step-out holes - Positive factor: Mineralization remains open in multiple directions - Positive factor: Significant expansion of claim area \(5,600 to 39,000 hectares\) - Positive factor: Strong treasury of C$12.5M to fund upcoming 10,000-20,000m program - Negative factor: Deeper drilling has not returned favorable vein widths due to poor host lithology Facts used in scoring: 4 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling in the Basalto Zone and Manchuria Hill Eastern Zone are described as 50m and 200m step-outs respectively. Evidence · text > 3 metres grading 4.34 g/t gold and 363.7 g/t silver in a 50 metre step-out at the new Basalto Zone **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: The release discloses the use of 152 blanks and 152 standards and names the laboratory. Evidence · text > A total of 152 Blanks and 152 standards \(2 different Au and Ag grade ranges\) were used as QAQC ## Extracted facts Stored fact records: 4.

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.
