## Minestarters Atlas summary

CMC Metals announced positive preliminary metallurgical results from North Bay Resources' testing of Mt. Vernon Gold Mine ore. The gravity recovery tests produced high-grade gold, platinum, and silver concentrates, marking the first known discovery of platinum at the site.

Reasoning: The testing revealed a first-known discovery of platinum at the Mt. Vernon mine with high-grade gold and platinum concentrates, significantly increasing the potential per-ton value of the ore.

- Positive factor: Discovery of platinum at Mt. Vernon

- Positive factor: High-grade concentrate results

- Positive factor: Successful gravity recovery circuit

- Negative factor: Preliminary/brevity testing scale

Facts used in scoring: 6

## Classification and evidence

**Free Milling**

Polarity: positive

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

Why it applies: The ore was successfully processed using a basic grind and gravity recovery circuit.

Evidence · text

> viability of extraction of gold, platinum, and silver using a basic grind and gravity recovery circuit

**Bench Scale Only**

Polarity: negative

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

Why it applies: The testing is described as preliminary brevity recovery testing on run-of-mine ore.

Evidence · text

> preliminary metallurgical/brevity recovery testing

**Mill Route**

Polarity: neutral

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

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

**Gravity Route**

Polarity: neutral

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

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

**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.
