Klondex Begins Construction of Midas Tailings Expansion

VANCOUVER, BC--(Marketwired - July 14, 2015) - Klondex Mines Ltd. (TSX: KDX) (OTCQX: KLNDF) ("Klondex" or the "Company") today reports the required permits for the tailings expansion at the Company's Midas project have been issued and construction of the expansion has kicked off.

The Nevada Division of Environmental Protection, Division of Water Resources, has granted the final permit for expansion of the Midas tailings impoundment. This permit acquisition allows Klondex to construct the Phase VI raise to the tailings impoundment, to a maximum elevation of 5,680 feet above mean sea level, adding approximately 400,000 tons of tailings capacity.

Klondex has contracted NewFields Engineering and Remington Construction to complete the raise. The raise is an engineered reinforced concrete wall, that when coupled with the existing tailings, will provide Klondex with approximately 900,000 tons of tailings capacity at Midas. Construction is expected to be completed in the fourth quarter of this year.

Brent Kristof, Klondex COO commented, "The tailings expansion permit is an important milestone in our long-term planning for Midas and Fire Creek. The expansion will provide Klondex with a timeline to be able to build a second tails dam at the Midas property. Studies to design, permit and construct a new, long term tailings facility have been initiated. Also, I'd like to thank the environmental team, for delivering the second major permit to Klondex within a month. The Water Pollution Control Permit at Fire Creek, and Tailings Expansion permit at Midas are key to supporting our long-term growth plan."

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.
