The hole intersected a high-grade silver intercept of 121.3 g/t Ag and 0.37 g/t Au over 1.5m, including a 20cm sub-interval at 870 ppm Ag. Reasoning: Hole PSE-18-03 confirmed anomalous silver and gold values in a new structure \(Aguayutla\) north of previous holes, validating the epithermal vein system concept. - Positive factor: Step-Out Extension - Positive factor: Bonanza Intercept - Positive factor: True Width Disclosed - Positive factor: QA/QC Disclosed Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole 3 tested the Aguayutla structure to the north of holes 1 and 2. Evidence · text > Hole 3 tested the east-west striking Aguayutla structure to the north of holes 1 and 2 **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 870 ppm Ag over 20cm is exceptionally high grade for this epithermal system. Evidence · table > 870.0 Context: 0.20 **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 Tawn Albinson as a Qualified Person \(QP\) under NI 43-101. Evidence · text > Tawn Albinson, M.Sc., President of the Company, is a Qualified Person, as defined in NI 43-101 ## Extracted facts Stored fact records: 8.

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.
