This expands the total RC Gold Project resource to 1.29 million ounces indicated and 3.83 million ounces inferred. Reasoning: The announcement of a maiden 2.25 Moz resource at Rhosgobel and the expansion of the total project resource to over 5 Moz represents significant exploration success and project scale growth. - Positive factor: Maiden resource estimate for Rhosgobel deposit - Positive factor: Significant expansion of total project resource - Positive factor: High-grade core identified at Rhosgobel - Positive factor: Non-refractory metallurgical results - Positive factor: Strong growth trajectory from 2023 maiden resource - Negative factor: Tungsten mineralization presence noted as unproven economically Facts used in scoring: 4 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: First formal MRE defined for the Rhosgobel Gold Deposit.

Geo., of GeoSim Services Inc. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: Cut-off grade of 0.30 g/t gold is explicitly stated for the estimates.

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.
