## Minestarters Atlas summary

Marimaca Copper announced exceptional high-grade copper and silver drill results from its Pampa Medina project, including 6m at 6.11% Cu and 24.0 g/t Ag. The drilling successfully extended the high-grade bornite zone 300m south and intersected mineralization in basement metasediments for the first time, indicating significant depth extension potential. These results are well above the project's historical average and peer comparisons, confirming the geological model and expanding the prospective area.

Reasoning: Marimaca Copper reported exceptional high-grade copper and strong silver intercepts from step-out drilling at Pampa Medina, extending the bornite zone and discovering new mineralization in basement metasediments, which significantly enhances the project's potential and geological understanding.

- Positive factor: Exceptional copper grades significantly above peer average and prior results

- Positive factor: Extension of high-grade bornite zone 300m south of previous drilling

- Positive factor: First intersection of mineralization in basement metasediments, expanding prospective stratigraphy

- Positive factor: Strong silver grades correlating with copper mineralization

- Positive factor: Long intercepts demonstrating continuity of mineralization

Facts used in scoring: 66

## Classification and evidence

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states that true widths are estimated at approximately 80% of reported intervals.

Evidence · text

> True widths are estimated at approximately 80% of reported intervals.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling program is explicitly described as 'ongoing step-out drilling' and extended the high-grade bornite zone 300m south and intersected mineralization in basement metasediments for the first time.

Evidence · text

> ongoing step-out drilling at the Pampa Medina deposit

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release mentions a full QA/QC program involving blanks, standards, and duplicates, and a Qualified Person sign-off.

Evidence · text

> A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

**JORC Compliant**

Polarity: positive

Story-specific tag

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: The technical information is stated to be reported under both JORC and NI43-101 standards.

Evidence · text

> information can be reported under both JORC and NI43-101 standards

**NI 43-101 Compliant**

Polarity: positive

Story-specific tag

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The technical information is stated to be reported under both JORC and NI43-101 standards, with a Qualified Person responsible for NI 43-101.

Evidence · text

> is the Qualified Person for the purposes of NI 43-101

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Sergio Rivera, VP Exploration, is named as the Qualified Person for NI 43-101 and Competent Person for JORC.

Evidence · text

> Sergio Rivera, Vice President of Exploration, Marimaca Copper Corp... is the Qualified Person for the purposes of NI 43-101 responsible for the design and execution of the drilling program.

**Cut-off Undisclosed**

Polarity: negative

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

Why it applies: The document explicitly states that no specific cut-off grade was used during grade width calculations.

Evidence · text

> No specific grade cap or cut-off was used during grade width calculations.

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.

Why it applies: The document states that no metal equivalents have been reported, meaning no assumptions for such calculations are disclosed.

Evidence · text

> No metal equivalents have been reported.

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: true\_width\_m is 6.4

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: qaqc\_disclosed is true

## 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.
