The project contains a significant historical NI 43-101 resource, though Ridgestone notes these estimates are historical and should not be relied upon for current operations. Reasoning: Ridgestone has signed an option agreement to acquire a 100% interest in the Guadalupe y Calvo project, which contains significant historical gold-silver resources. - Positive factor: Acquisition of an advanced-stage project - Positive factor: Significant historical high-grade resource - Positive factor: Expansion potential along strike and at depth - Negative factor: Historical resource estimates are not current and should not be relied upon - Negative factor: Acquisition subject to TSX Venture Exchange approval Facts used in scoring: 3 ## Classification and evidence **Nearology Play** Polarity: neutral Story-specific tag Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The project is described as complementing Ridgestone's existing Rebeico Project. Evidence · text > This project compliments our Rebeico Project **Historical Estimate Only** Polarity: negative Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling. Why it applies: The resource estimate was prepared by Endeavour Silver Corp. in 2012 and is considered historical by Ridgestone. Evidence · text > For Ridgestone's purposes, the estimate for GyC are considered to be historical estimates ## 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.
