The program targets the undrilled Cambaya 1 corridor, aiming to test high-grade mineralization identified through previous surface channel sampling. Reasoning: The company is commencing a new drilling phase targeting high-grade silver-gold mineralization identified via surface sampling. While no new drill assays are provided, the program targets high-potential undrilled areas. - Positive factor: Commencement of Phase 2 drilling targeting high-grade zones - Positive factor: Targeting undrilled high-level portion of the epithermal system - Positive factor: High-grade historical channel samples provide strong targets - Negative factor: No new assay results from current drilling yet Facts used in scoring: 18 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Phase 2 targets the Cambaya 1 corridor, an undrilled portion of the system 250m above Phase 1 areas. Evidence · text > The Phase 2 program will focus on the Cambaya 1 corridor, an undrilled, high-level portion of the epithermal system located more than 250 metres above the areas tested in Phase 1. **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release details QA/QC protocols including standards, blanks, and duplicates for both channel and drill samples. Evidence · text > QA/QC programs for channel samples using internal standard and blank samples; field and lab duplicates indicate good overall accuracy and precision. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: True widths are explicitly stated as unknown due to orientation uncertainty. Evidence · text > True widths of mineralization are unknown due to the unknown mineralized zones orientation. ## Extracted facts Stored fact records: 18.

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.
