## Minestarters Atlas summary

Cantex has announced successful preliminary flotation testwork at its North Rackla project in the Yukon. The tests produced premium-grade lead and zinc concentrates from high-grade, low-grade, and oxide composites, with significant silver credits reported in the lead concentrates.

Reasoning: Preliminary flotation testwork successfully produced premium-grade lead and zinc concentrates with significant silver credits across multiple ore domains.

- Positive factor: High-grade concentrates achieved \(>50% Pb and >60% Zn\)

- Positive factor: Strong silver credits in lead concentrates

- Positive factor: Successful recovery from both high-grade and low-grade sulphide and oxide domains

- Positive factor: Use of conventional, industry-standard flotation techniques

- Negative factor: Zinc recovery in oxide mineralization was noted as poor

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: Lead and zinc recoveries in sulphide composites reached 85.1% and 80.6% respectively, which are strong for these commodities.

Evidence · text

> High-Grade \(HG\) sulphide composites achieved 85.1% lead recovery \(at 53.6% Pb grade\) and 80.6% zinc recovery \(at a 61.8% Zn grade\).

**Mill Route**

Polarity: neutral

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

Why it applies: The results are based on conventional flotation techniques.

Evidence · text

> successfully demonstrated that conventional, industry standard sulphide flotation techniques can effectively separate

**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: The release names Shane Tad Crowie, P. Eng. of JDS Energy & Mining Inc. as the Qualified Person.

Evidence · text

## 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.
