## Minestarters Atlas summary

Aclara Resources announced positive results from a Feasibility Study for its flagship Carina Project in Brazil, detailing robust economics with an after-tax NPV of US$1.7 billion and an IRR of 26.9%. The study establishes the first NI 43-101 compliant Mineral Reserves for an ionic clay project, forecasting an 18-year life of mine with significant annual production of rare earth oxides, including NdPr, Dy, and Tb. The company also highlights a successful pilot plant campaign and a sustainable processing method, underpinning its mine-to-magnet strategy.

Reasoning: The Feasibility Study confirms the Carina Project's strong economic viability and establishes significant rare earth Mineral Reserves, supported by a proven metallurgical process and sustainable practices, although overall recovery is low and capital costs have increased.

- Positive factor: Robust economics with after-tax NPV of US$1.7 billion and IRR of 26.9%.

- Positive factor: First NI 43-101 compliant Mineral Reserves for an ionic clay project.

- Positive factor: Successful pilot plant campaign demonstrating metallurgical process.

- Positive factor: High plant recovery of 96.1% for rare earth oxides.

- Positive factor: Sustainable Circular Mineral Harvesting process with minimal environmental impact.

- Positive factor: High purity MREC product \(97.7%\).

- Negative factor: Overall rare earth recovery of 25.4% is low due to desorption efficiency.

- Negative factor: Initial capital cost increased by US$100.4 million compared to PFS.

- Negative factor: Reliance on Argus Media price forecast which assumes an independent supply chain outside of China, with risk of Chinese market intervention.

- Negative factor: Risk of increased capital and operating costs for the separation project in Louisiana.

Low confidence — this extraction should be reviewed alongside the original source.

## 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.
