## Minestarters Atlas summary

EDM Resources Inc. has announced successful final results from its Dense Media Separation \(DMS\) pilot plant study at the Scotia Mine. The study demonstrated that DMS pre-concentration can increase zinc feed grades by 18.4% and lead feed grades by 33.5%, with high recoveries of 88.4% for zinc and 99.7% for lead, potentially reducing overall processing costs and improving project NPV.

Reasoning: The DMS pilot plant results demonstrate successful pre-concentration, significantly increasing feed grades and maintaining high recoveries, which directly supports project economics.

- Positive factor: Significant grade increase for both zinc and lead via DMS

- Positive factor: High recoveries achieved in pilot plant \(88.4% Zn, 99.7% Pb\)

- Positive factor: Potential for reduced processing costs and improved project NPV

- Positive factor: QA/QC supported by SGS Canada P.Eng/QP sign-off

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 recovery of 88.4% and lead recovery of 99.7% are strong for the reported DMS/flotation route.

Evidence · text

> Recoveries of 88.4% of zinc and 99.7% of lead.

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves DMS pre-concentration followed by a flotation circuit.

Evidence · text

> prior to flotation

**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: Curtis Mohns, P.Eng. from SGS Canada Inc. is named as the Qualified Person.

Evidence · text

> Mr. Curtis Mohns, P.Eng., Senior Metallurgist for SGS Canada Inc. and a Qualified Person as defined under NI43-101, has approved the technical information

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

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

**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.
