The property features a large oxide gold stock-work system with historic high-grade trench intercepts, targeting an open-pit, heap-leachable deposit. Reasoning: Orestone has secured an option to a significant oxide gold system with high-grade historic surface expression, though current technical confidence is limited by the reliance on historical, non-compliant summary data. - Positive factor: Option to earn up to 85% interest in a 7 sq km property - Positive factor: High-grade historic trench intercepts up to 109 g/t gold - Positive factor: Targeting bulk tonnage oxide gold amenable to heap leach - Positive factor: Nearology play with proximity to large-scale regional projects - Negative factor: Data is historical and non-NI 43-101 compliant - Negative factor: Previous drilling was poorly oriented and did not adequately test target - Negative factor: Significant capital commitment required for option \($4.2M\) Facts used in scoring: 4 ## Classification and evidence **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The property is located in Salta, a region with numerous large-scale copper, gold and lithium projects. Evidence · text > Salta is a region of good infrastructure where numerous large-scale copper, gold and lithium projects are being developed. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: Historic trenching data is reported with widths but lacks drill orientation or true width verification. Evidence · text > High grade intervals of gold are noted in historic summary reports and on trench maps over widths of 3 to 14 metres with grades from 1 to 109 g/t gold. **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: A Qualified Person \(P.Geo\) has reviewed and approved the technical information. Evidence · text > Gary Nordin, P.Geo, a Director of the Company, is a qualified person as defined by National Instrument 43-101. Mr. Nordin has reviewed and approved the technical information in this press release. ## Extracted facts Stored fact records: 4.

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.
