## Minestarters Atlas summary

Probe Mines provided a metallurgical progress update for the Borden Gold project in Ontario, highlighting trade-off studies between two process routes. The results indicate that a whole ore leach \(WOL\) option may be superior and shows improved gold recovery curves compared to previous results.

Reasoning: The update provides progress on metallurgical trade-off studies, showing improved recovery curves compared to 2013 results, though specific recovery percentages are contained in an image rather than text.

- Positive factor: improvement over previous recovery curve

- Positive factor: encouraging results

- Positive factor: potential upside at higher grades

- Negative factor: results are subject to further analysis and PEA

Facts used in scoring: 2

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The metallurgical program focuses on whole ore leach and flotation/regrind circuits.

Evidence · text

> gravity + whole ore leach \("WOL"\)

**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.
