Additionally, the company will not proceed with the remaining closings of its previously announced non-brokered private placement. Reasoning: The company is halting drilling and a capital raise to undergo a strategic review, which is a significant corporate pivot that introduces uncertainty despite the underlying asset quality. - Positive factor: strategic review aims to maximize shareholder value - Positive factor: Ayawilca project has strong economics per 2024 PEA - Negative factor: planned drilling activities deferred - Negative factor: previously announced private placement will not proceed - Negative factor: strategic review introduces uncertainty regarding future transactions Facts used in scoring: 13 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document provides a summary of the existing Ayawilca mineral resource components. Evidence · text > The Zinc Zone at Ayawilca has an estimated Indicated Mineral Resource of 28.3 Mt grading 5.82% zinc ## Extracted facts Stored fact records: 13.

Evidence · text > Inferred Mineral Resource of 12.7 Mt grading 0.76% tin #### Tags used in scoring **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **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: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 **No Contained Metal** Polarity: negative Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting. Why it applies: contained\_metal was not reported **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: the release names the study this estimate supports ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
