Klondex Enters Into Toll Milling Agreement With LKA Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 3, 2014) - Klondex Mines Ltd. (TSX:KDX)(OTCQX:KLNDF) ("Klondex" or the "Company") announces that its subsidiary, Klondex Midas Operations, has entered into a toll milling agreement with LKA Gold, Inc. (OTCQB:LKAI) to process high grade ore produced from the Golden Wonder Mine at Klondex's Midas mill.

The toll milling agreement with LKA has a one year term beginning December 1, 2014, and is subject to renewal annually. Under the terms of the agreement, high grade ore, greater than 51.4 g/t (1.5 opt) Au from the Golden Wonder Mine, located near Lake City, Colorado, will be delivered to the Midas Mill for processing. Pursuant to the toll milling agreement, all dore produced will become the property of Klondex, and Klondex will pay LKA the value of the recovered gold minus all toll mill charges.

Mike Doolin, Klondex VP Business Development and Technical Services stated, "This agreement marks the second toll milling agreement put in place since we bought Midas in February. Processing third party material makes good use of the mill, while still leaving us with ample capacity as we continue to develop the Midas and Fire Creek mines. We look forward to working with the LKA team on the Golden Wonder project."

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.
