Klondex Enters Into Toll Milling Agreement With French Gulch

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 23, 2014) - Klondex Mines Ltd. (TSX:KDX)(OTCQX:KLNDF) announces that its subsidiary, Klondex Midas Operations, today entered into a toll milling agreement with French Gulch Nevada Mining Corp. to process gravity concentrates produced from the Washington Mine at Klondex's Midas mill.

Mike Doolin, Klondex VP Corporate Development stated, "This is a mutually beneficial agreement for both parties. Processing third party material makes excellent use of the excess capacity at the Midas Mill. Toll milling provides the Company with additional revenue, which will increase the cash flow from the operations."

The toll milling agreement with French Gulch Nevada Mining Corp has a one year term beginning April 17, 2014, and is subject to be renewed annually. Under the terms of the agreement, gravity concentrates from the Washington Mine, located in French Gulch, California, will be delivered to the Midas Mill for processing. The toll milling agreement is structured so that all dore produced from the concentrate will become the property of Klondex, and Klondex will pay French Gulch the value of the recovered gold minus all toll mill charges.

Klondex is presently evaluating other toll milling opportunities to determine which materials are best suited to being processed at the Company's Midas Mill.

Cautionary Note Regarding Technical Information and Forward-looking Information

A production decision at the Midas mine was made by prior owners of the mine, prior to the completion of the acquisition of the Midas mine by Klondex. To the knowledge of Klondex, this production decision was not based on a feasibility study of mineral reserves demonstrating economic and technical viability prepared in accordance with NI 43-101 but was based on internal studies conducted by the prior owner of the mine. Klondex has no reason to believe that the data on which such studies were based or that the results of such studies are unreliable. However, readers are cautioned that there is increased uncertainty and higher risk of economic and technical failure associated with such production decisions.
