## Minestarters Atlas summary

Canadian North Resources reported successful second-set bioleaching test results for the Ferguson Lake Project, achieving up to 99% nickel, 98% cobalt, and 90.6% copper extraction. The tests demonstrated a self-sustaining process at low temperatures \(52-65°C\) and showed promising cyanide leach recoveries for gold and PGMs from the bioleaching residues.

Reasoning: The second set of bioleaching tests confirmed exceptionally high extraction rates for nickel \(up to 99.4%\) and cobalt \(up to 99.3%\) at low temperatures, with a self-sustaining mechanism that could significantly reduce OPEX.

- Positive factor: High extraction rates for Ni, Co, and Cu

- Positive factor: Self-sustaining bioleaching process \(low energy/acid requirement\)

- Positive factor: High PGM and gold recoveries from residues

- Negative factor: Bench-scale testing only

Facts used in scoring: 9

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Nickel, cobalt, and copper recoveries reached up to 99%, 99%, and 90% respectively.

Evidence · text

> High metal extractions with 99% Ni, 98% Co and 90.6% Cu confirmed

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The release describes the results as 'bench-scale tests'.

Evidence · text

> confirmed in the second set of bioleaching lab-scale tests

**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: Dr. Trevor Boyd, P.Geo. is named as the Qualified Person who reviewed and approved the release.
