Mr. Sandy McVey reports


West Vault Mining Inc. has released the results of an independent National Instrument 43-101 prefeasibility study prepared by U.S.-based engineering firm Respec Company LLC for West Vault’s 100-per-cent-owned Hasbrouck gold project located near Tonopah, Nev. West Vault intends to file the Technical Report on SEDAR (www.sedar.com) within 45 days of this news release.

The Technical Report updates a September 2016 Pre-feasibility Study (“2016 PFS”), necessary because of the possible effect of increased capital costs, operating costs, and metal prices on project economics, and their combined effects on Mineral Resource and Mineral Reserve. After completion of the Technical Report, it has been determined that the mine plan, mineral processing, and Mineral Resource and Mineral Reserve Statements are substantially unchanged from the 2016 PFS. Exploration and expansion potential on the fully permitted project is highlighted.

The Technical Report was prepared by largely the same team that prepared the 2016 PFS, headed by RESPEC (formerly Mine Development Associates) of Rapid City, South Dakota, with contributions from Kappes, Cassidy & Associates, Reno (“KCA”), NewFields Mining Design & Technical Services (“NewFields”), Jorgensen Engineering & Technical Services (“JE&TS”), and Westland Engineering & Environmental Services (formerly EM Strategies).

The Hasbrouck Gold Project consists of the Three Hills and Hasbrouck Deposits plus a large land package, located near Tonopah, Nevada. All dollar values presented in this news release are in U.S. dollars.

Sandy McVey, West Vault’s CEO, commented, “We are very pleased with the results of the Technical Report. Not only does it confirm that the project is strong economically, but more importantly it demonstrates how leveraged it is to the price of gold, going from 43% IRR in 2016 to 51% IRR now. This validates our thesis that our shareholders should benefit through their ownership of a high-quality project in an excellent jurisdiction and knowing that we will hold to our strategy of patiently letting the gold cycle do the work of increasing value, avoiding the risk of going to construction too early.”

Regarding expansion potential, there are a number of significant gold intercepts located proximal to current Mineral Resources, on strike from and below the proposed open pits that are not incorporated into the Technical Report Mineral Resource model. These intercepts show the potential to increase and extend the known Mineral Resource on West Vault’s property.

The Technical Report estimates a modest initial capital of US$66M for the Phase 1 Three Hills Mine. The Phase 2 Hasbrouck Mine is estimated to cost US$123M, and this money is planned to come from free cash flow generated at the Three Hills Mine. The Technical Report does not include mineralized material at the Company’s Hill of Gold property located between Three Hills Mine and Hasbrouck Mine.


West Vault is committed to maximizing shareholder value through its low-risk gold-in-ground strategy, which involves acquiring, advancing, and holding high-quality development gold projects in the best jurisdictions.
