About Klondex Mines Ltd. (www.klondexmines.com)
We are a well-capitalized, junior-tier gold and silver mining company focused on exploration, development, and production in a safe, environmentally responsible, and cost-effective manner. We have 100% interests in two producing mineral properties: the Fire Creek project and the Midas mine and ore milling facility, both of which are located in the State of Nevada, USA. Our milling and processing facilities, which are located at Midas, process mineralized material from both Midas and Fire Creek. Fire Creek is located approximately 100 miles south of Midas.

Cautionary Language to Forward-Looking Statements

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.
