The program aims to complete a mineral resource estimate \(MRE\) with the option to proceed to a Preliminary Economic Assessment \(PEA\). Reasoning: The agreement allows for the first unconstrained evaluation of the integrated Coimolache/AntaKori project, providing a clear path to a PEA and potentially unlocking significant value through resource integration. - Positive factor: Strategic collaboration to evaluate integrated project - Positive factor: Pathway to PEA established - Positive factor: Access to adjacent Coimolache sulphides resource Facts used in scoring: 14 ## Classification and evidence **Nearology Play** Polarity: neutral Story-specific tag Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The AntaKori project is described as immediately adjacent to and interfingered with Coimolache concessions. Evidence · text > The AntaKori project is immediately adjacent to and interfingered with mineral concessions owned by Coimolache **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: AntaKori resource data is cited from a NI 43-101 technical report. Evidence · text > NI 43-101 Technical Report , dated February 22, 2019 **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: Dr. Kevin B. Heather is named as the Qualified Person for the AntaKori data. Evidence · text > reviewed and approved by Dr. Kevin B. Heather, Chief Geological Officer, FAusIMM, who serves as the qualified person \(QP\) ## Extracted facts Stored fact records: 14.

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.
