The project features proven and probable reserves of 7.13 million tonnes and is targeting commissioning in July 2027. Reasoning: The document provides a detailed update on the construction progress and economic parameters of the El Domo project, highlighting a significant carried interest for Salazar. - Positive factor: Strong reserve economics with 45% IRR - Positive factor: Carried interest structure de-risks capital expenditure - Positive factor: Construction is fully funded - Positive factor: Improved metallurgical recoveries reported - Negative factor: Salazar is not the operator and lacks control over construction/budget - Negative factor: Jurisdictional risk in Ecuador - Negative factor: Pre-revenue status Facts used in scoring: 6 ## 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 mentions the NI 43-101 technical report underpinning the project figures. Evidence · text > The NI 43-101 technical report underpinning the project figures is available on the Company's website **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: Qualified Persons Yanfang Zhao and Falong Hu are named as responsible for the resource and reserve estimates. Evidence · text > Ms. Yanfang Zhao \(MAIG\) was responsible for the mineral resource estimate and Mr. Falong Hu \(FAusIMM\) was responsible for the mineral reserve estimate. ## 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.
