## Minestarters Atlas summary

Myriad Uranium Corp. announced encouraging initial results from high-pressure slurry ablation \(HPSA\) testing on samples from its Copper Mountain Uranium Project. The batch-scale tests demonstrated significant uranium recovery into a fines concentrate \(up to 90.6%\) and substantial mass reduction \(up to 87.9%\), alongside successful reduction in radionuclide activity.

Reasoning: Initial HPSA technology testing shows strong potential for uranium pre-concentration and mass reduction, though results are limited to batch-scale laboratory testing.

- Positive factor: High uranium recovery in fines concentrate \(up to 90.6%\)

- Positive factor: Significant mass reduction \(up to 87.9%\)

- Positive factor: Successful radionuclide reduction \(Ra-226 and Th-230\)

- Positive factor: Third-party lab \(Energy Labs\) and QP \(George van der Walt\) sign-off

- Negative factor: Batch-scale testing only \(not pilot or continuous\)

- Negative factor: Small sample size \(50 kg\)

Facts used in scoring: 3

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Uranium recovery in fines concentrate reached 90.6% in the second time interval sample.

Evidence · table

> 90.6%

Context: 67.5%

**Bench Scale Only**

Polarity: negative

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

Why it applies: Testing was conducted in a batch-style HPSA unit using 50 kg of sample material.

Evidence · text

> subjected to initial material characterization... followed by HPSA testing in a batch-style HPSA unit

**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: Release mentions third-party laboratory \(Energy Labs\) and QP sign-off by George van der Walt.

Evidence · text

> performed by a third-party laboratory \(Energy Labs\)

**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: George van der Walt, MSc., Pr.Sci.Nat., FGSSA, is named as the Qualified Person.

Evidence · text

> reviewed and approved by George van der Walt, MSc., Pr.Sci.Nat., FGSSA, a "Qualified Person"

**Mill Route**

Polarity: neutral

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

Why it applies: the document describes a flotation route \("concentrate"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested

## 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.
