Klondex Mines Begins Drifting on New Hui Wu Vein at Fire Creek; Weighted Average of 126.9 g/t (3.7 opt) Gold Over a 1.1 Meter (3.5 ft) Vein Width and 11 Meters (37 ft) Along Strike - Seite 2

Channel assays were analyzed by SGS Minerals Services (Elko, Nevada) and Dave Francisco Lab (Fallon, Nevada), and drill assays were analyzed by ALS Chemex (Reno, Nevada) and American Assay Labs (Sparks, Nevada) under Klondex staff supervision. These are all independent laboratories. Sampling a given face is conducted after the face location has been washed, measured, mapped in detail and photographed. Continuous rock-chip channel samples are then collected by Klondex staff directly into 11" x 17" sample bags from the footwall, vein, and hanging wall. Individual samples are defined by geology and do not exceed 3' in length in order to better define the location of grade. Salient features including sample number, channel length, location on face, rock type, and alteration are documented. Blank samples are inserted into the sample stream to help monitor QA/QC of the labs. Channel samples and respective assays are loaded into an Access database, and ultimately visualized in Vulcan where they are correctly located in space and utilized in resource estimation.

About Klondex Mines Ltd. (www.klondexmines.com)

Klondex Mines 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 producing gold and silver since 1998. Fire Creek is located ~100 miles south of Midas and is operating an ongoing bulk sampling program that began in 2013 and is in the process of obtaining the full mining permit. All major infrastructure is in place at Fire Creek.

Cautionary Note Regarding Technical Information and Forward-looking Information

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.
