## Minestarters Atlas summary

EDM Resources Inc. has announced positive results from its Dense Media Separation \(DMS\) pilot plant study at the Scotia Mine. The study demonstrated that DMS can pre-concentrate ore, increasing zinc and lead feed grades by 18.4% and 33.5% respectively, while maintaining high recoveries.

Reasoning: The DMS pilot plant successfully demonstrated significant grade upgrades \(18.4% Zn, 33.5% Pb\) and high recoveries \(88.4% Zn, 99.7% Pb\), which directly supports project economics through cost reduction and increased throughput.

- Positive factor: Significant grade increase for both primary and secondary metals

- Positive factor: High recoveries achieved via DMS pre-concentration

- Positive factor: Potential for significant reduction in processing costs and waste

- Positive factor: Pilot plant results validate bench-scale HLS tests

Facts used in scoring: 4

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Zinc and lead recoveries in the DMS pilot plant \(88.4% and 99.7%\) are very high for a pre-concentration step.

Evidence · text

> The lead and zinc recoveries were 99.7% and 88.4%, respectively.

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves DMS followed by a grinding and flotation circuit.

Evidence · text

> A DMS plant could be added prior to the Flotation Circuit in the existing processing building.

## 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.
