Step-out drilling successfully extended the mineralized sedimentary horizon by 300m to the south and west. Reasoning: Significant step-out success and high-grade intercepts in a central sulfide zone confirm expansion of the Pampa Medina system. - Positive factor: Thick high-grade copper-silver intercepts - Positive factor: Step-out drilling extends mineralized horizon by 300m - Positive factor: Strong lateral and vertical continuity demonstrated - Positive factor: High-grade sulfide zone confirmed - Negative factor: Apparent widths reported without specific true widths \(estimated at 80%\) - Negative factor: Scout RC holes failed to reach target horizon in some areas Facts used in scoring: 10 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Step-out holes extended the mineralized sedimentary horizon 300 m to the south and west. Evidence · text > Step-out holes extended the mineralized sedimentary horizon 300 m to the south and west of the central corridor. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Intercepts of 3.05% Cu and 3.25% Cu are exceptionally high grade. Evidence · text > 14 m of 3.05% copper and 26.7 g/t silver from 606 m depth **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: All intervals are reported as downhole lengths, with true widths only estimated at 80%. Evidence · text > All intervals are reported as downhole lengths, and true widths are estimated at approximately 80% of the reported figures. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIP"\) ## Extracted facts Stored fact records: 10.
