The company is also preparing a Preliminary Economic Assessment \(PEA\) for completion in September 2026 and remains fully funded into 2027. Reasoning: The company is advancing multiple workstreams including an imminent MRE update and PEA, supported by a strong cash position and proactive permitting efforts. - Positive factor: Advanced MRE modeling in progress - Positive factor: Upcoming PEA expected in September - Positive factor: Fully funded into 2027 - Positive factor: Proactive environmental baseline studies Facts used in scoring: 4 ## Classification and evidence **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The document explicitly states the Indicated Mineral Resource is NI 43-101 compliant. Evidence · text > The Santa Fe Mine has a Canadian National Instrument 43-101 compliant Indicated Mineral Resource **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The company is currently modeling an updated MRE to be announced in the coming weeks. Evidence · text > An updated MRE is expected to be announced in the weeks ahead. **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 grades for oxide and non-oxide resources are clearly stated. Evidence · text > Mineral resources are reported using a cut-off grade of 0.15 g/t AuEq for oxide resources and 0.60 g/t AuEq for non-oxide resources. ## 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.
