The project is underpinned by 99.2% Measured and Indicated resources, with an estimated initial capital cost of US$191.2 million. Reasoning: Supplementary information for the Tiros PEA providing key economic and metallurgical parameters. The high proportion of M&I resources \(99.2%\) provides strong geological confidence for the production target, though the study remains at a preliminary scoping stage. - Positive factor: High M&I confidence \(99.2%\) - Positive factor: Long mine life \(20 years\) - Positive factor: Clear production target \(500 ktpa\) - Negative factor: PEA/Scoping stage uncertainty - Negative factor: Bench-scale metallurgical basis Facts used in scoring: 5 ## Classification and evidence **PEA Only** Polarity: neutral Definition: Only Class 4 / Initial Assessment economics available. Not bankable. Why it applies: The document describes the announcement as a Preliminary Economic Assessment \(PEA\) equivalent to a Scoping Study. Evidence · text > The PEA remains preliminary in nature and is equivalent to a Scoping Study under the JORC Code \(2012\). **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The production target includes a small 0.8% component from Inferred resources. Evidence · text > 0.8% by Inferred Mineral Resources **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Metallurgical recovery assumptions are based on bench-scale testwork. Evidence · text > based on bench-scale testwork **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## 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.
