The project, which is construction-ready with its primary environmental permit secured, is expected to be acquired by Camino in early April 2025. The PFS highlights a 14.2-year mine life, low initial capital of US$141.9 million, and an AISC of US$2.00 per pound of copper. Reasoning: Camino Minerals has filed a Pre-Feasibility Study \(PFS\) technical report for the Puquios Copper Project, highlighting robust economics with a post-tax NPV of US$118 million and an IRR of 23.4%. The project benefits from low initial capital and has received its primary environmental permit, positioning it as construction-ready. The acquisition of this project is a significant step towards the company becoming a copper producer, despite the resource and reserve estimates having effective dates from 2021. - Positive factor: Robust project economics with strong post-tax NPV and IRR - Positive factor: Low initial capital expenditure for a copper project - Positive factor: Primary environmental permit received, advancing project towards production - Positive factor: Acquisition of a construction-ready project, accelerating company's growth strategy - Positive factor: Significant Measured and Indicated resource base supporting a long mine life - Negative factor: Mineral Resource effective date is over 3 years old, potentially impacting currency - Negative factor: Mineral Reserve effective date is over 3 years old, potentially impacting currency Facts used in scoring: 37 ## Classification and evidence **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.
