Additionally, rock chip sampling at White Spar returned silver grades up to 432 g/t, potentially adding a silver stream to their processing plans. Reasoning: Drilling at Antimony Canyon confirmed high-grade stibnite pods, and surface sampling at White Spar returned significant silver grades, supporting a mine-to-metal strategy. - Positive factor: High-grade antimony intercepts confirmed - Positive factor: Discovery of a second discrete high-grade pod - Positive factor: Silver sampling shows significant potential Facts used in scoring: 5 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The 68.1% antimony sub-interval is exceptionally high grade. Evidence · text > 0.36m at 68.1% **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling confirmed a second discrete high-grade pod, extending the known mineralized system.

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.
