The estimate also includes 181,400 ounces of Measured & Indicated oxide gold \(0.37 g/t\) and 1,203,500 ounces of Inferred oxide gold \(0.32 g/t\). This MRE establishes a strategic U.S. antimony resource and provides a pathway for potential near-term antimony production from already mined surface material, with significant expansion potential identified for future drilling. Reasoning: NevGold announced its maiden Mineral Resource Estimate for the Limo Butte Project, establishing a significant gold-antimony resource in Nevada. The MRE includes substantial Measured and Indicated resources for both commodities, with a focus on strategic antimony supply and oxide gold. The estimate is NI 43-101 compliant and provides a strong foundation for future project development, including potential near-term antimony production. - Positive factor: Maiden Mineral Resource Estimate for gold and antimony - Positive factor: Defines a strategic U.S. antimony resource - Positive factor: Includes Measured, Indicated, and Inferred categories for both commodities - Positive factor: 100% oxide gold amenable to heap leaching - Positive factor: NI 43-101 compliant and signed off by a Qualified Person - Positive factor: Potential for near-term antimony production from surface material - Positive factor: Significant potential for resource expansion with ongoing drill programs - Negative factor: High proportion of Inferred resources \(87% of total gold ounces, 72% of total antimony tonnes\) - Negative factor: No prior MRE for direct comparison of growth metrics Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 73 ## 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: The document explicitly states this is NevGold's 'maiden gold-antimony Mineral Resource Estimate'.

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.
