Summary
West Vault Mining announced an updated Pre-Feasibility Study for its Hasbrouck Gold Project, confirming robust economics with a 51% after-tax IRR and a NPV(5%) of US$206 million. The project, located in Nevada, is construction-ready and features proven and probable reserves totaling 44.0 million tons containing 753,000 ounces of gold and 10.5 million ounces of silver. Metallurgical test work indicates a 75% average heap-leach gold recovery.
Reasoning: The updated Pre-Feasibility Study confirms robust project economics with a high IRR of 51% and a NPV(5%) of US$206 million, building on a construction-ready project with significant gold and silver reserves. While the underlying resource and reserve estimates are largely unchanged from the 2016 PFS, the updated economic parameters provide a positive re-evaluation.
Positive factors
- High IRR
- Construction-ready
- NI 43-101 Compliant
- QP/CP Signed
- Good gold recovery
- Significant contained metal
Negative factors
- Resource/reserve estimates largely unchanged from 2016
Facts used in scoring: 25
Classification and evidence
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 prepared by Qualified Persons and Expert Relied Upon under NI 43-101, including Thomas L. Dyer, Jeff Bickel, Mark Jorgensen, Ryan Baker, and Carl Defilippi, who reviewed and approved the information.
Evidence · text
“Each person is either a "Qualified Person" or an "Expert Relied Upon" under NI 43-101 and has reviewed and approved the information in this news release relevant to the portion of the Technical Report for which they are responsible.”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The Technical Report was prepared in conformance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects.
Evidence · text
“The Technical Report was authored by RESPEC and was prepared in conformance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (" NI 43-101 ").”
PFS-Supportingneutral
Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.
Why it applies: The document announces the results of an updated Pre-Feasibility Study for the Hasbrouck Gold Project.
Evidence · text
“West Vault Mining Announces 51% IRR Pre-Feasibility Study Update for Hasbrouck Gold Project”
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: The Technical Report updates a September 2016 Pre-feasibility Study, including updated Mineral Resource and Mineral Reserve Statements.
Evidence · text
“The Technical Report updates a September 2016 Pre-feasibility Study (" 2016 PFS ")”
Proven Reservepositive
Measured Resource with demonstrated economic viability after applying modifying factors.
Why it applies: The document reports Proven Mineral Reserves for both the Hasbrouck Mine and the total project.
Evidence · table
“Proven”
Context: 6,130
Probable Reservepositive
Indicated Resource with demonstrated economic viability after applying modifying factors.
Why it applies: The document reports Probable Mineral Reserves for the Three Hills Mine, Hasbrouck Mine, and the total project.
Evidence · table
“Probable”
Context: 9,653
Measured Resourcepositive
Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.
Why it applies: The Hasbrouck Deposit Mineral Resources include a Measured category.
Evidence · table
“Measured”
Context: 6,987
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: Both Hasbrouck and Three Hills Deposits report Indicated Mineral Resources.
Evidence · table
“Indicated”
Context: 35,041
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: Both Hasbrouck and Three Hills Deposits include Inferred Mineral Resources, which are considered speculative.
Evidence · table
“Inferred”
Context: 5,161
Heap Leach Routeneutral
Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
Why it applies: The metallurgical section explicitly states '75% average heap-leach gold recovery'.
Evidence · table
“75% average heap-leach gold recovery”
Context: Metallurgy
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: An average heap-leach gold recovery of 75% is considered strong for this processing route.
Evidence · table
“75% average heap-leach gold recovery”
Context: Metallurgy
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: The project's geology is described as 'well-understood' with '+600 boreholes' and '13 test programs', implying comprehensive domain coverage.
Evidence · table
“well-understood, +600 boreholes, all-oxide”
Context: Geology
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: Cut-off grades are disclosed for both mineral resources (e.g., 0.007oz AuEq/ton) and reserves (e.g., 0.005 oz Au/ton or $5.17/ton GMV).
Evidence · text
“0.007oz AuEq/ton Cutoff”

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.
