About Klondex Mines Ltd. (www.klondexmines.com)
Klondex is focused on the exploration, development and production of its two high quality gold and silver projects in the mining-friendly jurisdiction of north central Nevada. The 1200 tpd milling facility is processing mineralized materials from the Midas Mine and the Fire Creek Project. Midas is fully-permitted and has been in operations since 1998. Fire Creek is located ~100 miles south of Midas and is operating an ongoing bulk sampling program that began in 2013. All major infrastructure is in place at Fire Creek.

Cautionary Language Regarding Technical Information
A production decision at the Fire Creek Project has not been made by Klondex, as it is still in the bulk sampling phase. Although a production decision at the Fire Creek Project has not been made, the mineralized material extracted from the Fire Creek Project under the bulk sample permit is processed through the Midas mill.
A production decision at the Midas mine was made by previous operators of the mine prior to the completion of the acquisition of the Midas project by Klondex and Klondex made a decision to continue production subsequent to the acquisition. This decision by Klondex to continue production and, to the knowledge of Klondex, the production decision made by the previous operator were not based on a feasibility study of mineral reserves demonstrating economic and technical viability prepared in accordance with National Instrument 43-101. Readers are cautioned that there is increased uncertainty and higher risk of economic and technical failure associated with such production decisions.
