The Locked Cycle Test results show very low levels of deleterious elements in both concentrates, which is expected to enhance marketability and improve offtake terms. These positive results de-risk the project and support a potential low-capital restart pathway for Selkirk. Reasoning: The final analytical results from the Locked Cycle Test confirm that both copper and nickel concentrates meet commercial smelter specifications with very low levels of deleterious elements, enhancing marketability and de-risking the project. While the testwork is bench-scale and based on a single composite, the positive concentrate quality is a significant milestone. - Positive factor: clean\_concentrate\_profile - Positive factor: meets\_smelter\_specifications - Positive factor: low\_deleterious\_elements - Positive factor: qp\_signed - Positive factor: accredited\_lab - Positive factor: ni\_43\_101\_compliant - Negative factor: bench\_scale\_only - Negative factor: single\_domain\_only Facts used in scoring: 52 ## Classification and evidence **QP/CP Signed** Polarity: positive Story-specific tag 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.

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.
