West Kirkland Mining Announces Positive Hasbrouck Updated
After-Tax US$120 Million NPV; 43% IRR; US$47 Million Initial Capital
VANCOUVER, BRITISH COLUMBIA, September 1, 2016 – West Kirkland Mining Inc. (WKM:TSXV) (“West Kirkland” or the “Company”) is pleased to announce the results of an independent pre-feasibility study (the “2016 PFS”) of its Hasbrouck Project. The 2016 PFS updates the July 2015 pre-feasibility study (the “2015 PFS”) with value engineering, detailed scheduling, revised contractor cost estimates, an updated gold price and various other changes. Refinements to the Life of Mine (“LOM”) plan and economic model in the 2016 PFS are positive, and the updated gold price provides additional value. Mineral Reserves and Resources are unchanged from the 2015 PFS. Exploration potential near the fully permitted Three Hills open pit is highlighted. The 2016 PFS and the 2015 PFS were both prepared by a team of Qualified Persons headed by Mine Development Associates (MDA) of Reno, Nevada.
The Hasbrouck Project consists of the Hasbrouck and the Three Hills deposits and surrounding land package, located near Tonopah, Nevada. All dollar values presented in this news release are in U.S. dollars and are presented on a 100% project basis. Highlights include:
- 594,000 recoverable gold equivalent ounces
- 74,000 gold equivalent ounces annually for eight years
- $661 Adjusted Operating Cost per ounce
- $709 All-In Sustaining Cost per ounce
- $120 million NPV (5%) and a 43% IRR, after-tax, with a 3.1 year pay-back
- $1,275/oz Au and $18.21/oz Ag metal price assumptions
- $47 million initial capital
- No change to Mineral Resources or Reserves from the 2015 PFS
- Good exploration potential proximal to the Three Hills permitted pit
- Fully permitted Three Hills Mine, shovel-ready
The Company has a 75% interest in the Hasbrouck Project with rights to the remaining 25% owned by Waterton Precious Metals Fund II Cayman, LP. Waterton’s 25% interest is fully participating and the holder must contribute to capital or be diluted.
“On a global basis the Hasbrouck Project is one of only a handful of shovel-ready, high margin gold projects. The Hasbrouck Project is very simple construction and the first phase can be commenced today”, said Sandy McVey, West Kirkland’s Chief Operating Officer. The Hasbrouck and Three Hills deposits are all-oxide with low stripping ratios, minimal pre-strip, and no adverse environmental or cultural factors. The resources and their metallurgy have been well-studied and analyzed. Good infrastructure exists nearby consisting of accommodations, grid electricity, paved highways and multiple water sources. The Phase 1 Three Hills Mine is fully permitted and permitting work for the Phase 2 Hasbrouck Mine is underway. For further information on permitting at Three Hills please refer to the Company’s November 27, 2015 news release.
The completion of the 2016 PFS confirms strong operating margins for the Hasbrouck Project.

The following information is taken from the 2016 PFS and “will” refers to the plan if a positive construction decision is made and the project financed. The 2016 PFS estimates initial capital at $47 million (2015 PFS - $54 million) which will be used to construct the Phase 1 Three Hills Mine. Capital to build the Phase 2 Hasbrouck Mine will come from free cash flow generated by Three Hills. Six million tons of ore will be processed annually to produce 74,000 gold-equivalent ounces per year for eight years. Adjusted Operating Costs are projected to be $661 per ounce of gold, with All-In Sustaining Costs of $709 per ounce of gold, both net of silver by-product credits.
The Three Hills and Hasbrouck deposits are 8 kilometers apart and located within a large land position hosting multiple near-surface gold intercepts. Known gold intercepts are located proximal to current resources; these are not included in the resource model. These intercepts present exploration targets with the potential to increase and extend known resources.
The 2016 PFS estimates Phase 1 production for two years at the Three Hills Mine followed by Phase 2 production for six years at the Hasbrouck Mine. Combined production is estimated at 594,000 gold equivalent ounces. LOM stripping ratio is estimated at 1.1:1. LOM head grade is estimated at 0.6 g/t gold (0.017 oz Au/ton) while gold recovery from heap leaching is estimated at 76%.
A Carbon-In-Columns (“CIC”) plant will be installed at the Three Hills Mine. Gold will be stripped from carbon off-site by a contractor. An Adsorption-Desorption-Recovery plant (ADR) complete with CIC will be installed at the Hasbrouck Mine to handle the greater amount of silver at Hasbrouck.

Cautionary Note to U.S. Investors Regarding the Use of Mining Terms
This press release has been prepared in accordance with the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resources and reserve estimates included in this press release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the U.S. Securities and Exchange Commission (the “SEC”) Industry Guide 7, and resource or reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, “resources” and “reserves” established under NI 43-101 standards may not qualify as “resources” and “reserves” under U.S. standards. Under U.S. standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. In addition, under U.S. standards, a “Final” or “Bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in-place tonnage and grade without reference to unit measures. Accordingly, information concerning mineral deposits set forth in this press release may not be comparable with information made public by companies that report in accordance with U.S. standards.
