## Minestarters Atlas summary

Gunnison Copper has launched a major district-wide drilling program consisting of up to 120 holes totaling approximately 42,000 meters. The program is designed to support Pre-Feasibility Study \(PFS\) activities, including resource expansion, metallurgical optimization via column leach testing, and resource conversion.

Reasoning: The announcement of a large-scale, fully contracted drilling and metallurgical program provides a clear roadmap for advancing the project toward a PFS and mineral reserves.

- Positive factor: Major district-wide drilling program announced

- Positive factor: Program supports PFS work and resource conversion

- Positive factor: Includes metallurgical optimization with column leach tests

- Positive factor: Significant capital commitment of US$15.0M

Facts used in scoring: 2

## Classification and evidence

**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 names a Qualified Person \(Dr. Roland Goodgood\) responsible for the technical information.

Evidence · text

> Dr. Roland Goodgood, Senior VP of Project Development of the Company is a Qualified Person as defined by NI 43-101.

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: the document describes a heap\_leach route \("heap leach"\)

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: drill\_program\_type is "mixed"

## 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.
