## Minestarters Atlas summary

NorthWest Copper Corp. reported successful 2025 metallurgical test results at the Kwanika project, demonstrating that a refined flowsheet including flotation and tails leaching significantly improves recoveries. Total gold recoveries reached 94.6%-96.3% and silver reached 96.3%, representing material improvements over previous test work.

Reasoning: The metallurgical program successfully demonstrated material improvements in overall gold \(34%\) and silver \(37%\) recoveries by adding a leaching stage to flotation tails, significantly enhancing the project's economic potential.

- Positive factor: Significant improvement in gold and silver recoveries via optimized flowsheet

- Positive factor: Demonstrated ability to recover precious metals from flotation tails

- Positive factor: High concentrate grades for copper, gold, silver, and palladium

- Positive factor: Use of conventional processing methods \(ball milling, flotation, leaching\)

Facts used in scoring: 6

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Gold total recovery of 94.6%-96.3% is in the exceptional band for a mill route.

Evidence · text

> Gold recoveries ranging from ~94.6% to 96.3%

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The process involves ball mill grinding, flotation, and leaching.

Evidence · text

> conventional processing methods, including ball mill grinding, flotation and tails leaching

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: Technical aspects reviewed and approved by Qualified Persons \(Geoff Chinn, P.Geo and Stacy Freudigmann, P.Eng\).

Evidence · text

> Technical aspects of this news release have been reviewed, verified, and approved by Geoff Chinn, P.Geo... and Stacy Freudigmann P.Eng.
