## Minestarters Atlas summary

Abasca Resources Inc. announced positive results from a Preliminary Economic Assessment \(PEA\) for its Loki Flake Graphite Deposit, projecting an after-tax NPV of US$130 million and an IRR of 16.7%. The study outlines a 19-year open-pit operation producing 66,500 tonnes of 95% Cg concentrate annually, based on an updated mineral resource estimate. The company plans to advance the project towards a Feasibility Study and secure necessary permits.

Reasoning: Abasca announced positive results from a Preliminary Economic Assessment \(PEA\) for its Loki Flake Graphite Deposit, showing an after-tax NPV of US$130 million and an IRR of 16.7%. The study projects a 19-year mine life with strong metallurgical recovery and is based on an updated mineral resource estimate. While the economics are positive, the PEA nature and reliance on a significant inferred resource component introduce inherent uncertainty. The company plans to advance towards a Feasibility Study.

- Positive factor: Positive after-tax NPV and IRR for the PEA, indicating economic viability.

- Positive factor: Long mine life of 19 years, providing exposure to multiple price cycles.

- Positive factor: High metallurgical recovery of 92.3% to concentrate, achieved with conventional flotation.

- Positive factor: Updated Mineral Resource Estimate forms the basis of the study, with a significant indicated component.

- Positive factor: Project benefits from existing infrastructure and proximity to power and road access.

- Negative factor: The study is a Preliminary Economic Assessment \(PEA\), which is conceptual in nature and includes inferred resources, carrying higher uncertainty.

- Negative factor: IRR of 16.7% is moderate, suggesting sensitivity to price fluctuations or cost increases.

- Negative factor: Payback period of 4.7 years is moderate, indicating a longer capital return time.

- Negative factor: The PEA is based on an updated MRE, but the MRE itself includes a substantial inferred component \(15.83 Mt Inferred vs 6.99 Mt Indicated\).

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