## Minestarters Atlas summary

West Vault Mining announced an updated Pre-Feasibility Study \(PFS\) for its Hasbrouck Gold Project in Nevada, reporting a robust 51% after-tax IRR and a $206 million NPV at a 5% discount rate. The study highlights a fast 2.9-year payback and an All-in Sustaining Cost of $877 per gold ounce, with the project being permitted and construction-ready. While the economic parameters show significant improvement over the 2016 PFS, the underlying Mineral Resource and Reserve estimates are noted as substantially unchanged.

Reasoning: West Vault Mining has released a highly positive updated Pre-Feasibility Study for its Hasbrouck Gold Project, showing a robust 51% after-tax IRR and a $206 million NPV, representing a significant improvement over the prior 2016 PFS. The project is permitted and construction-ready, indicating advanced de-risking. However, the lack of explicit price sensitivity disclosure reduces transparency.

- Positive factor: High IRR

- Positive factor: Fast Payback

- Positive factor: Significant NPV Increase

- Positive factor: Permitted Project

- Positive factor: Low Strip Ratio

- Positive factor: NI 43-101 Compliant

- Negative factor: No Price Sensitivity Disclosure

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.
