Klondex Enters Into Definitive Agreement With Newmont to Acquire the Midas Mine and Mill Complex and Announces Acquisition Financing

VANCOUVER, BC--(Marketwired - Dec 4, 2013) - Klondex Mines Ltd. (TSX: KDX) ("Klondex" or the "Company") is pleased to announce that it has entered into a definitive agreement to acquire the Midas mine and related ore milling facility located in the State of Nevada (collectively, "Midas") for approximately US$83 million (the "Acquisition") from a subsidiary of Newmont Mining Corporation ("Newmont").

The purchase price, which is subject to customary adjustments, is comprised of (i) approximately US$55 million in cash, and (ii) the replacement of Newmont surety arrangements with Nevada and federal regulatory authorities in the amount of approximately US$28 million. In addition, Klondex will issue to Newmont 5 million common share purchase warrants of the Company with a 15-year term, subject to acceleration in certain circumstances, and an exercise price to be specified on the closing date of the Acquisition.

Paul Huet, President and CEO of Klondex, commented, "This acquisition is transformational for Klondex, during a pivotal point in our company's development. I am confident that Klondex's management team can leverage past experience, with some of the core leadership team having previously worked at Midas, to vastly benefit from the synergies and to unlock continued value in Klondex for shareholders going forward. Our team is extremely pleased to be working alongside Newmont to bring together two excellent epithermal deposits with a high-quality central mill."

The Acquisition is anticipated to close in early 2014, subject to the fulfillment of various closing conditions, including the receipt of requisite regulatory approval and other third party consents, and entry into certain ancillary arrangements with Newmont for the provision of transition services.

In addition to acting as exclusive financial advisor with respect to the Acquisition, GMP Securities L.P. has also been engaged by the Company to coordinate the financing of the Acquisition, which is expected to consist of a combination of equity, secured notes and a secured gold loan. Further details on the financing of the Acquisition will be provided once determined.
