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

Klondex Mines Ltd. has begun initial drifting on Fire Creek's fourth identified vein, the Hui Wu vein. The vein is located 30.5 metres (100 feet) west of the main ramp and 15.2 m (50 feet) east of the Karen vein. The structure was identified as a target during the 2013 drill program (see press release dated Jan. 21, 2014), but was not included in the 2013 mineral resource estimate or subsequent preliminary economic assessment, with respect to the Fire Creek project (see press release dated April 29, 2014).

Based on current drilling, the known strike length of the Hui Wu vein is 243.8 m (800 feet) and the known vertical dip extent is 76.2 m (250 feet), remaining open both north and south along strike, and up and downdip.

To date, 11 m (37 feet) of exploration development has been completed along strike of the Hui Wu vein. Face samples range from 31.6 grams per tonne (g/t) (0.9 ounce per ton) gold (Au) to 395.9 g/t (11.5 ounces per ton) Au. The weighted average grade of samples taken from the Hui Wu vein is 126.9 g/t (3.7 ounces per ton) Au over an average vein width of 1.1 m (3.5 feet). The fully diluted mined grade averaged 60.8 g/t (1.8 ounces per ton) Au over an average mining width of 2.2 m (7.4 feet). Assay results from samples from the Hui Wu vein are summarized and detailed in the associated table.

Brent Kristof, Klondex Mines chief operating officer, commented: "The Fire Creek team has done an exceptional job continuing the drilling, sampling and mapping program to identify yet another mineralized area. The Hui Wu vein represents another growth opportunity to be targeted during our 2014 and 2015 exploration and development programs."

Channel assays were analyzed by SGS Minerals Services (Elko, Nev.) and Dave Francisco Lab (Fallon, Nev.), and drill assays were analyzed by ALS Chemex (Reno, Nev.) and American Assay Labs (Sparks, Nev.) 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-inch-by-17-inch sample bags from the footwall, vein and hangingwall. Individual samples are defined by geology and do not exceed three feet 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 (quality assurance/quality control) 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.
