## Minestarters Atlas summary

EDM Resources Inc. announced successful initial Heavy Liquid Separation \(HLS\) test results on high-grade zinc and lead composite samples from its Scotia Mine. The bench-scale tests, simulating Dense Media Separation \(DMS\), showed exceptional recoveries of up to 99.4% for lead and 97.6% for zinc, alongside significant grade increases for both metals. These results suggest a strong potential to reduce mineral processing costs and access previously uneconomic areas of the deposit.

Reasoning: Initial HLS test work on high-grade zinc and lead samples from the Scotia Mine demonstrated excellent recoveries \(97.3-99.4%\) and significant grade increases \(up to 35% for zinc, 26% for lead\) at an optimal SG of 3.00, indicating a strong potential for cost reduction and improved economics through pre-concentration via DMS.

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: Zinc recoveries of 97.3-97.6% and lead recoveries of 99.4% are exceptionally high for the DMS process, indicating excellent metal separation.

Evidence · text

> retaining 97.3% of the Zinc and 99.4% of the Lead

**Bench Scale Only**

Polarity: negative

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

Why it applies: The tests are Heavy Liquid Separation \(HLS\), which is a bench-scale process simulating DMS, not a pilot plant, indicating early-stage test work.

Evidence · text

> initial Heavy Liquid Separation \("HLS"\) test results

**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: Mr. Curtis Mohns, P.Eng., a Qualified Person, approved the technical information related to the HLS test work.

Evidence · text

> Mr. Curtis Mohns, P.Eng., Senior Metallurgist for SGS Laboratories and a Qualified Person as defined under NI43-101, has approved the technical information contained in this news release related to the HLS test work.

**Free Milling**

Polarity: positive

Definition: Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The Dense Media Separation process is described as a 'relatively simple, environmentally friendly and cost-efficient metallurgical process'.

Evidence · text

> As a relatively simple, environmentally friendly and cost-efficient metallurgical process

**Single Domain Only**

Polarity: negative

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

Why it applies: The tests were performed on two 10-kilogram samples collected from 'high-grade mineralized zones', suggesting limited variability testing across different ore domains.

Evidence · text

> performed on material from two 10-kilogram samples that were collected from the high-grade mineralized zones of the Scotia Mine

## 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.
