Minestarters Atlas analysis
Summary
Marimaca Copper reported significant step-out drill results at the Pampa Medina project in Chile, extending the copper-silver system by 300 metres. 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 factors
- Significant step-out extension of 300m
- High-grade copper-silver intercepts
- Thick mineralized zones (up to 216m)
- Continuity demonstrated across 3-km area
Negative factors
- True width not explicitly stated (estimated at 80% of downhole)
Facts used in scoring: 15
Classification and evidence
Step-Out Extensionpositive
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 Onlynegative
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”
