## Minestarters Atlas summary

Camino Minerals and Nittetsu have commenced proprietary leaching studies in Tokyo to assess scale-up opportunities for the Puquios Copper Project in Chile. The project is planned as a conventional sulphide leaching operation using SX-EW technology, with construction anticipated in the first half of 2026.

Reasoning: The announcement marks a transition from exploration/permitting to metallurgical optimization and construction preparation for the Puquios project.

- Positive factor: Commencement of proprietary leaching studies for scale-up

- Positive factor: Permits for construction are already in place

- Positive factor: Strategic partnership with Nittetsu for metallurgical R&D

- Positive factor: Path towards production in 1H 2026

- Negative factor: Studies are at the R&D/proprietary stage, not yet commercial scale

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 project is planned as a conventional sulphide leaching operation utilizing SXEW technology.

Evidence · text

> utilizing solvent extraction and electro winning \(" SXEW "\) technology

**Bench Scale Only**

Polarity: negative

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

Why it applies: Studies are being conducted at a research and development facility in Tokyo rather than at a pilot or commercial scale.

Evidence · text

> initiate leaching studies at Nittetsu's metallurgical and chemical facility in Tokyo

## 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.
