Mining Stock News - West Vault Mining (TSXV: WVM) (OTCQX: WVMDF) Announces 51% IRR Pre-Feasibility Study Update For Hasbrouck Gold Project

(MENAFN- Investor Ideas)

West Vault Mining Inc. (TSXV: WVM) (OTCQX: WVMDF) ('West Vault' or the 'Company') is pleased to announce the results of an independent NI 43-101 Pre-feasibility Study ('Technical Report') prepared by USA-based engineering firm RESPEC Company LLC ('RESPEC') for West Vault's 100% owned Hasbrouck Gold Project located near Tonopah, Nevada. West Vault intends to file the Technical Report on SEDAR ( 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.

Non-IFRS Reporting Measures

'Cash Costs', 'All-in Sustaining Costs' and 'All-in Costs' are not Performance Measures reported in accordance with International Financial Reporting Standards ('IFRS'). These performance measures are included because these statistics are key performance measures that management uses to monitor performance. Management uses these statistics to assess how the Project ranks against its peer projects and to assess the overall effectiveness and efficiency of the contemplated mining operations. These performance measures do not have a meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Note to US Investors

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms 'Mineral Resource', 'Indicated Mineral Resource' and 'Inferred Mineral Resource' are defined in and required to be disclosed by NI 43-101. However, these terms are not defined terms under SEC S-K 1300 and are normally not permitted to be used in reports and registration statements filed with the SEC. In addition, the terms 'Mineral Reserve', 'Probable Mineral Reserve' and 'Proven Mineral Reserve' are also defined in NI43-101 and not S-K 1300. Investors are cautioned not to assume that all or any part of an 'Indicated Mineral Resource' or 'Inferred Mineral Resource' will ever be upgraded to a higher category or converted into Mineral Reserves in accordance with S-K 1300. 'Inferred Mineral Resources' have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable. Disclosure of 'contained ounces' in a Mineral Resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute 'Reserves' by SEC S-K 1300 standards as in-place tonnage and grade without reference to unit measures. Accordingly, information contained in this News Release contains descriptions of the Company's mineral deposits that may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
