Summary
West Vault Mining announced an updated Pre-Feasibility Study for its Hasbrouck Gold Project, reporting a post-tax NPV(5%) of US$206 million and an IRR of 51% at a US$1,790/oz gold price. The study outlines an initial capital cost of US$66 million and a rapid payback period of 2.9 years. The project, located in Nevada, is fully permitted and construction-ready, with updated Mineral Resource and Reserve estimates supporting the economic assessment.
Reasoning: The updated Pre-Feasibility Study for the Hasbrouck Gold Project demonstrates significantly improved economics with a 51% IRR and US$206 million NPV, driven by higher gold prices. The project is fully permitted, construction-ready, and located in a tier-1 jurisdiction, with a low initial capital cost and fast payback. While the underlying mine plan and resource/reserve remain largely consistent with the prior study, the enhanced financial metrics are a strong positive.
Positive factors
- Significant increase in post-tax IRR from 43% to 51% and NPV from US$120M to US$206M compared to the 2016 PFS, indicating improved project economics.
- Project is fully permitted and construction-ready in a favorable jurisdiction (Nevada).
- Low initial capital cost of US$66 million and a fast payback period of 2.9 years.
- All-in Sustaining Cost (AISC) of US$877/oz net of by-product credits positions the project favorably.
- Resource and reserve estimates are updated and compliant with NI 43-101, providing a solid foundation for the economic study.
Negative factors
- The mine plan, mineral processing, and Mineral Resource and Mineral Reserve Statements are substantially unchanged from the 2016 PFS, suggesting the economic improvement is primarily driven by metal price assumptions rather than significant operational or geological optimizations.
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 19
Classification and evidence
PFS Completepositive
AACE Class 3 study complete.
Why it applies: The document announces the results of an independent NI 43-101 Pre-feasibility Study ('Technical Report').
Evidence · text
“West Vault Mining Announces 51% IRR Pre-Feasibility Study Update for Hasbrouck Gold Project”
High IRRpositive
Post-tax real unlevered IRR in the strong tier or better.
Why it applies: The post-tax IRR of 51% is well above the strong tier threshold of 25%.
Evidence · table
“51%”
Context: IRR (after-tax, $1,790 gold)
Fast Paybackpositive
Payback in the strong tier or better, on the required basis.
Why it applies: The payback period of 2.9 years is within the strong tier threshold of 3 years.
Evidence · table
“2.9 years”
Context: Pay-back
Conservative Pricingpositive
Conservative on the worst of the spot, 3-year and consensus comparisons.
Why it applies: The study uses a gold price of $1,790/oz, which is stated as the three-year trailing average gold price at January 17, 2023, indicating a conservative approach.
Evidence · text
“The $1,790/oz gold price represents the three-year trailing average gold price at 17 January 2023.”
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: The Technical Report was authored by RESPEC, and technical work, analysis, and findings were completed by Thomas L. Dyer, P.E., and Jeff Bickel, C.P.G. both of RESPEC, who are Qualified Persons.
Evidence · text
“Technical work, analysis, and findings were completed by Thomas L. Dyer, P.E., and Jeff Bickel, C.P.G. both of RESPEC”
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: The resource and reserve estimates are prepared in accordance with NI 43-101 standards.
Evidence · text
“All estimates of Mineral Resource have been prepared in accordance with NI 43-101 standards.”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: A current resource fact retains the disclosed cut-off grade
Heap Leach Routeneutral
Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
Why it applies: the document describes a heap_leach route ("heap leach")

Reasoning: The reported 75% average heap-leach gold recovery is a strong result for this processing route, supporting the project's economic viability.
Positive factors
- 75% gold recovery for a heap leach operation is considered strong and economically viable.
- Extensive test programs (13) indicate thorough metallurgical understanding.
Evidence · table
“75% average heap-leach gold recovery”
Context: Metallurgy
Tags used in scoring
Heap Leach Routeneutral
Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
Why it applies: processing_route matches the heap_leach signal
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: 75% is at or above the exceptional band (75%)
Byproduct Commodityneutral
The tested commodity is a byproduct rather than the primary economic driver.
Why it applies: the release describes a byproduct credit
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.
