Vancouver, BC - February 13, 2014 - Klondex Mines Ltd. (TSX: KDX; OTCQX: KLNDF), a gold exploration and development company, today provides an update on recent underground infill and exploration drilling from its Fire Creek gold project near Elko, Nevada.  A total of seventeen drill holes were drilled to the east of the main decline from Muck Bay (MB) 6 and Diamond Drill Station (DDS) 6 and 17 ( See FIGURE 1 ).

Drilling east from MB6, designed to test the northern extension of the Vonnie vein, intersected the Vonnie structure in all five holes of the fan.  The lower two holes successfully extended mineralization at depth, from 42.7 m (140 ft) to 96 m (315 ft) below the current workings.  The location of mineralization intersected in these holes is consistent with the known geometry of mineralization along the Vonnie vein.  The upper three holes did not encounter mineralization above the cut-off grade of 5 g/t (0.15 opt) Au.

Drilling east from DDS-17 continues to demonstrate continuity of mineralization along the Joyce vein. Drill intercepts on the Joyce vein extended mineralization north by 61 m (200 ft) along strike of the current underground development, and by 27 m (90 ft) down dip and 46 m (150 ft) up dip.  FC-13-107U identified one new mineralized structure northeast of the Vonnie vein, continuing to support and demonstrate the potential for finding additional mineralization within the Fire Creek property.  Drilling encountered the Vonnie structure, but did not locate mineralization above the cut-off grades.  Klondex will continue testing the northern extensions of the veins, by extending the main decline to the northwest to establish additional drill platforms. 

Infill fan drilling from DDS 6 extended the Joyce and the Vonnie vein mineralization, slightly updip and downdip. Additional fan drilling is currently underway in DDS 6. Assays are pending.

Mike Doolin, Klondex General Manager stated, "Our drilling program continues to impress us as we have intersected several new areas of gold and silver mineralization. This continues to support our geologic model that there is a strong likelihood to encounter additional subparallel veins within the East and West zones.  Our planned infill and exploration drill programs for 2014 will be expanded in all directions in an effort to increase the current known mineral resources at Fire Creek."
