Indicated resources grew by 90% to 40.2 million AgEq ounces at 454 g/t AgEq. Reasoning: The company released an updated PEA for Tonopah West, showing a massive 90% increase in Indicated resources and strong economic metrics. - Positive factor: Significant increase in Indicated resources - Positive factor: Strong PEA economics \(28% IRR, US$437M NPV5%\) - Positive factor: High-grade silver-equivalent grades Facts used in scoring: 2 ## Classification and evidence **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Indicated resources increased 90% from previous estimate where all ounces were inferred. Evidence · text > Today we are presenting a high-confidence project underpinned by a substantial indicated resource base of 40.2 million silver equivalent ounces, nearly double what we reported in our previous resource estimate **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: Indicated resources increased by 90% compared to the previous estimate. Evidence · text > Indicated resources increased 90% to 40.2 million AgEq ounces ## Extracted facts Stored fact records: 2.

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.
