The maiden resource comprises 6.5 million tonnes of Inferred material grading 2.9% Zn, 1.2% Pb, 0.6% Cu, and 35 g/t Ag. Reasoning: The announcement of a maiden MRE for the Sesmarias project provides a significant baseline for the asset, though the high proportion of Inferred resources and limited metallurgical data represent technical risks. - Positive factor: Maiden Mineral Resource Estimate established - Positive factor: NI 43-101 compliant - Positive factor: Clear exploration targets identified to expand resource - Negative factor: 100% Inferred category limits economic confidence - Negative factor: Metallurgical testing is only at a basic/preliminary stage Facts used in scoring: 5 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: This is the first formal MRE for the Sesmarias project. Evidence · text > completion of its NI 43-101-compliant, initial Mineral Resource Estimate \(“MRE”\) **All Inferred** Polarity: negative Definition: M&I share below the weak bound — very early stage, no engineering confidence. Why it applies: The entire reported resource consists of the Inferred category. Evidence · text > Total Inferred Mineral Resource Estimate of 6.5 million tonnes **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Frank Browning \(SLR Consulting\) and Paul W. Kuhn are named as responsible persons. Evidence · text > Frank Browning, who is a Qualified Person as defined by NI 43-101... compiled the Sesmarias MRE. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The release explicitly states the MRE is NI 43-101 compliant. Evidence · text > completion of its NI 43-101-compliant, initial Mineral Resource Estimate **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: While a ZnEq cutoff is mentioned, the specific technical/economic parameters used for the calculation are described as being at a preliminary stage. Evidence · text > Technical and economic parameters used in the MRE cut-off grade calculation are at a preliminary stage of evaluation **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: A current resource fact retains the disclosed cut-off grade ## Extracted facts Stored fact records: 5.

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.
