## Minestarters Atlas summary

Probe Mines provided a metallurgical progress update for the Borden Gold project, highlighting an improved gold recovery curve for the Whole Ore Leach \(WOL\) option compared to 2013 results. The program includes extensive comminution and metallurgical testing to support an upcoming Preliminary Economic Assessment \(PEA\).

Reasoning: The update shows improving metallurgical recovery curves compared to previous years and provides a clear path toward a PEA, though results are still in the preliminary stage.

- Positive factor: improvement over 2013 results

- Positive factor: QP sign-off provided

- Positive factor: multiple labs used

- Positive factor: comprehensive comminution testing

- Negative factor: results are preliminary/PEA-supporting

- Negative factor: trade-off studies still subject to further analysis

Facts used in scoring: 1

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The program evaluates whole ore leach and flotation/leach routes involving regrinding.

Evidence · text

> compare the two main process options: 1\) gravity + whole ore leach \("WOL"\); and 2\) gravity + flotation + leach

**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: The release states the contents were approved by Mr. Jacques McMullen, P.Eng, Qualified Person of BBA Inc.

#### Identity

- Commodity: gold
- Ticker: PRB

#### Test Work

- Program Status: preliminary
- Test Type: whole ore leach
- Processing Route: gravity + whole ore leach \(WOL\)
- Sample: WOL option at 75 μm
- Grind P80: 75 µm

#### Recovery

- Recovery Basis: unspecified

#### Lab

- Laboratory: SGS Mineral Services \(Lakefield\)
- Consultant: BBA Inc.

#### Review

- Needs Review: No
- Historical: No

#### Dates

- Event date: 2014-06-10T00:00:00.000Z

Reasoning: The company identified an optimum grind size and noted improvements in the recovery curve over previous data.

- Positive factor: optimum grind identified

- Positive factor: improvement over 2013 curve

Evidence · text

> The resulting metallurgical recovery curve \(WOL at 75 μm\) is presented in Figure 1. This updated grade recovery curve shows an overall improvement over the curve released in April 2013 .

## 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.
