## Minestarters Atlas summary

Marimaca Copper is advancing the Pampa Medina project with simultaneous delineation of a central high-grade zone and scout drilling for extensions. While northern scout holes failed to reach target sediments due to depth, step-out drilling successfully extended the mineralized horizon 300m to the south and west.

Reasoning: Strong step-out results to the south and west extend the system, though northern/northwestern extensions are currently constrained by depth and drilling method \(RC limits\).

- Positive factor: Step-Out Extension

- Positive factor: delineation of central zone

- Negative factor: scout holes failed to reach target depth

- Negative factor: drilling method constraints

#### Tags used in scoring

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: qaqc\_disclosed is not true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "The first fills in a defined area of interest measuring 3 kilometers \(km\) by 1.5km in Chile's Antofagasta Region, about "

## 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.
