Klondex Samples 22,396 gpt (653 opt) Gold Over 0.15m (0.5ft) on the Vonnie Structure at Fire Creek in Nevada

ELKO, NV and VANCOUVER, BC--(Marketwired - Jun 27, 2013) - Klondex Mines Ltd. (TSX: KDX) (OTCQX: KLNDF) ("Klondex" or the "Company") is pleased to announce the results of additional exploration drifting and metallurgical sampling on the Vonnie vein at its Fire Creek gold project in Nevada. Highlights of the channel sampling results (Figures 1 and 2) include assays of 20,231 g/t (590 ounces per ton) Au, 15,891 g/t (463 opt) Au, and 22,396 g/t (653 opt) Au, 63ft, 69ft and 74ft north of the 5400 cross cut, respectively. The complete set of results of channel sample assays is set out in Table 1 below.

The high-grade gold mineralization was encountered while following up on a surface drill intercept from FC-12-11S that returned 2,910 g/t Au (85 opt Au) over 1.5m (4.8ft) as announced on September 24, 2012. As a part of the exploration and sampling program, Klondex is assaying the Vonnie vein after each exploration round.

Paul Huet, Klondex President and CEO, commented, "We are very encouraged by these results. With our team's substantial expertise in narrow vein systems, we expect to be able to minimize dilution while maximizing grade. We anticipate that these grades will allow us to be more selective in our mining process."

Steve McMillin, Klondex Chief Geologist, stated, "Sampling improves our understanding of structures, provides a much better geological understanding of the deposit and identifies targets for follow-up drilling. Current drilling continues to confirm the continuity of mineralization as we move south on 75 foot centers along the ramp."

The potential quantities and grades of the mineralization reported above are conceptual in nature and there has been insufficient work to date to define a mineral resource in the Vonnie Vein structure. Furthermore, it is uncertain if further exploration will result in discovery of a mineral resource in this area of the Fire Creek project.

Sampling a given face is conducted after the face location has been measured, photographed, and mapped in detail. Continuous rock-chip channel samples are then collected by Klondex staff in 11" x 17" sample bags from the footwall, vein, and hanging wall. Salient features including sample number, channel length, location on face, rock type, and alteration are documented. Samples are sent to SGS Mineral Services Division lab in Elko, Nevada, an independent laboratory, for gravimetric fire assay analysis with blanks and standards.
