This milestone completes the federal environmental approval process, allowing the company to advance toward development planning and financing. Reasoning: The receipt of key environmental permits \(SEMARNAT\) is a major de-risking milestone for the Cordero project, clearing the final major regulatory hurdle for development. - Positive factor: Receipt of key federal environmental and land-use permits - Positive factor: Completion of federal environmental approval process - Positive factor: Large scale proven and probable reserves - Positive factor: Project becomes more financeable and strategically valuable - Negative factor: Development planning and financing still required before construction Facts used in scoring: 4 ## Classification and evidence **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: The document references a feasibility study which implies professional sign-off, though the specific name is not in this text snippet.

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.
