Preliminary rock chip sampling yielded high-grade values including up to 1.2 kg/t Ag and 3.97 wt% Cu, suggesting a large integrated epithermal-skarn system. Reasoning: Discovery of a new polymetallic skarn zone with high-grade silver and copper intercepts in a large-scale system. - Positive factor: New discovery of polymetallic skarn - Positive factor: High grade silver and copper intercepts - Positive factor: Large scale potential \(1km outcrop\) - Positive factor: Structural continuity across caldera - Negative factor: Sampling is only rock chips \(grab samples\) - Negative factor: Full extent of complex undetermined Facts used in scoring: 2 ## Classification and evidence **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 mentions ALS Labs and QP sign-off by Robert Johansing. Evidence · text > n = 20 -- ALS Labs **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The discovery is positioned as a 'mirror image' to the existing Las Minas area. Evidence · text > These two mineralized skarn zones appear to be ‘mirror images' ## Extracted facts Stored fact records: 2.

Why it applies: no cutoff\_grade was stated #### Rejected tags **Step-Out Extension** — Rejected; excluded from scoring Polarity: positive Definition: Mineralization extended beyond the previously known limit. Reason: Discovery of a new skarn zone west of the previously known epithermal trend. Evidence · text > new area of skarn-hornfels alteration and mineralization was identified ## 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.
