## Minestarters Atlas summary

Big Ridge Gold Corp. reported positive results from its 2026 metallurgical program at the Hope Brook Gold Project, achieving 90.3% copper recovery and 88% overall gold recovery. The program utilized a locked-cycle flotation and cleaner-tail leaching flowsheet, producing a high-grade concentrate containing 24% copper, 300 g/t gold, and 93 g/t silver.

Reasoning: The metallurgical program achieved high recoveries for both copper and gold, with the overall gold recovery \(88%\) outperforming historical milling results at similar feed grades.

- Positive factor: Strong copper and gold recoveries

- Positive factor: High-grade concentrate produced

- Positive factor: Overall gold recovery exceeds historical production levels

- Positive factor: Successful locked-cycle flotation testing

Facts used in scoring: 6

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The program uses a conventional flotation and leaching flowsheet.

Evidence · text

> Simplified conventional processing flowsheet consisting of primary grinding, copper flotation, concentrate cleaning and leaching of cleaner tailings.

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Achieved 90% copper and 88% gold recovery.

Evidence · text

> 2026 Metallurgical Program Achieves 90% Copper Recovery And 88% Gold Recovery

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: the document describes a heap\_leach route \("heap leach"\)

**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: 3 distinct composites were tested
