The company has expanded its claim group from 5,600 to 39,000 hectares and plans a follow-up 10,000-20,000 metre drill program to test regional targets. Reasoning: The release reports strong high-grade step-out intercepts that extend the known mineralized system and define new regional targets, supported by a significant increase in claim area. - Positive factor: High-grade gold and silver intercepts - Positive factor: Step-out drilling extends mineralization in multiple directions - Positive factor: Mineralization remains open - Positive factor: Expansion of claim group significantly increases project footprint - Negative factor: Deeper drilling has returned poor vein widths due to host lithology Facts used in scoring: 5 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The release reports 50m and 200m step-out intercepts at the Basalto Zone and Manchuria Hill Eastern Zone.
