## Minestarters Atlas summary

Revival Gold has released interim results from its 2026 Mercur Project column leach testing program. The testing, conducted by KCA, evaluates the impact of crush size and cement agglomeration on gold and silver leachability for both oxide and refractory materials in support of a Prefeasibility Study.

Reasoning: Interim column leach results show strong gold recovery for oxide ores but highlight significant metallurgical complexity in refractory domains.

- Positive factor: amenability to conventional crushed ore heap leaching

- Positive factor: high gold recovery in oxide domains \(up to 94%\)

- Negative factor: low gold recovery in some refractory domains \(1%\)

- Negative factor: refractory material shows lower leachability

Facts used in scoring: 4

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The testing is described as column leach testing in support of a PFS, which is a standard component of heap leach/mill flowsheet studies.

Evidence · text

> metallurgical column leach testing

**Refractory Ore**

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: The document explicitly mentions testing refractory \(sulfidic and carbonaceous\) materials.

Evidence · text

> assessing the leachability of refractory \(sulfidic and carbonaceous\) materials

**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 \("heap leaching"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested
