Additionally, surface mapping and grab sampling at the Tavares Norte target suggest a significant extension of the sericite alteration zone and the presence of high-grade gold, copper, and molybdenum. Reasoning: The completion of the first deep hole at Maria Bonita and the extension of the alteration zone at Tavares Norte are significant exploration milestones, though the primary drill results are still pending. - Positive factor: significant lithological thickness - Positive factor: extension of alteration zone - Positive factor: high-grade surface samples - Negative factor: assay results pending for deep hole - Negative factor: grab samples are not representative Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The sericite alteration zone at Tavares Norte extends 1.5km further east than previously known. Evidence · text > suggests that the sericite alteration zone extends 1.5km further east than previously known **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The Tavares Norte target is positioned 1.5km north-west of the Cajueiro Central resource. Evidence · text > located 1.5km north-west of the Cajueiro Central resource ## Extracted facts Stored fact records: 6.

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.
