## Minestarters Atlas summary

Myriad Uranium Corp. has announced encouraging initial results from high-pressure slurry ablation \(HPSA\) testing conducted by DISA Uranium. The tests demonstrated that the technology can reduce rock mass by approximately 70% while achieving uranium recoveries in the fines concentrate of up to 90.6%.

Reasoning: Initial HPSA technology testing shows strong ability to concentrate uranium into a small mass fraction with high recovery and cleaner waste.

- Positive factor: Significant mass reduction \(70%\)

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

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

- Positive factor: Effective pre-concentration potential

- Negative factor: Batch-scale testing only

- Negative factor: Requires scale-up to confirm commercial viability

Facts used in scoring: 2

## 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%, which is strong for initial pre-concentration testing.

Evidence · text

> calculated recoveries of uranium in the fines concentrate were 83.9%... and 90.6%

**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, which is a preliminary scale.

Evidence · text

> subjected to initial HPSA testing in a batch-style HPSA unit

**Mill Route**

Polarity: neutral

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

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

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was 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.
