Notable intercepts include 216 metres at 0.96% Cu and 7.2 g/t Ag in hole SPRD-15. Reasoning: Strong step-out drilling results at Pampa Medina extending the copper-silver system and demonstrating high-grade continuity. - Positive factor: Significant step-out extension of 300m - Positive factor: High-grade copper-silver intercepts - Positive factor: Thick mineralized zones \(up to 216m\) - Positive factor: Continuity demonstrated across 3-km area - Negative factor: True width not explicitly stated \(estimated at 80% of downhole\) Facts used in scoring: 15 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Step-out drilling pushed the copper-silver system 300 metres beyond earlier holes. Evidence · text > step-out drilling pushed the copper-silver system 300 metres beyond earlier holes **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: The company estimates true widths at about 80% of reported downhole lengths, meaning reported widths are apparent. Evidence · text > Marimaca estimates true widths at about 80% of reported downhole lengths ## Extracted facts Stored fact records: 15. Some facts used in scoring do not have a stored record. ## Drill Results (15) ### SPRD-15 [Link to this fact](https://atlas-staging.minestarters.com/news/marimaca-hits-thick-copper-silver-zone-at-pampa-medina-in-chile--3c28ab2d-36e8-4f55-9c26-fd8482b589b1#fact-drill-facts-0) Pampa Medina · copper #### Identity - Hole ID: SPRD-15 - Project: Pampa Medina - Commodity: copper - Region: chile - Reported Region: chile - Ticker: MARI #### Geometry - Grade: 0.96 - Grade Unit: % - Intercept: 216 m - From: 466 m - To: 682 m - Intercept Depth: 466 m #### Classification - Sample Type: drill - Group ID: SPRD-15:466-682 #### QA/QC - QA/QC Disclosed: Yes - QA/QC Methods: standards, blanks #### Review - Needs Review: No - Interp.
