## Minestarters Atlas summary

Marimaca Copper Corp. announced new assay results from its 2026 step-out exploration drilling program at the Pampa Medina copper-silver project in Chile. The program continues to demonstrate exceptional grade and continuity of the sediment-hosted manto-type mineralization, with multiple broad, high-grade copper and silver intercepts. Key results include 424m at 0.38% Cu and 2.2 g/t Ag in SPRD-06, and 166m at 0.50% Cu and 3.9 g/t Ag in SPRD-02, with several higher-grade sub-intervals. The company reports that the drilling validates the consistency of mineralization and expands the mineralized sedimentary horizon.

Reasoning: The new assay results from the ongoing step-out drilling program at Pampa Medina demonstrate exceptional high-grade copper and silver mineralization over significant widths, successfully expanding the known deposit and confirming geological continuity. The presence of multiple stacked mantos and robust QA/QC procedures further de-risk the project, indicating strong potential for a large-scale, high-quality copper-silver system.

- Positive factor: Exceptional copper grades, with several intercepts exceeding 2% Cu, including 4.60% Cu over 4m and 4.14% Cu over 2m.

- Positive factor: Significant intercept lengths, including 424m, 166m, and 146m, demonstrating broad mineralization.

- Positive factor: Step-out drilling successfully expanded the known mineralized footprint, confirming continuity over significant distances.

- Positive factor: Multiple high-grade stacked mantos identified, indicating a robust and extensive mineralized system.

- Positive factor: Comprehensive QA/QC program disclosed, including blanks, standards, and duplicates, with sign-off by a Qualified/Competent Person under NI 43-101 and JORC standards.

- Negative factor: Some intercepts were affected by pre and post mineral dyking, which can complicate continuity.

- Negative factor: True width is estimated as 80-90% of downhole intersection, but not explicitly calculated for each intercept, requiring some interpretation.

Low confidence — this extraction should be reviewed alongside the original source.

Reasoning: This intercept demonstrates significant width and a strong copper grade, contributing positively to the understanding of the deposit's scale and continuity in a step-out context.

- Positive factor: Significant intercept length of 146m, indicating broad mineralization.

- Positive factor: Copper grade of 0.41% is strong for an open-pit deposit.

- Positive factor: Part of a step-out drilling program, contributing to resource expansion.

## 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.
