Klondex Mines Intercepts New Areas of Gold Mineralization at Its Fire Creek Project

RENO, NEVADA and VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 19, 2013) - Klondex Mines Ltd. (TSX:KDX)(OTCQX:KLNDF), a Nevada gold exploration and development company, today reports gold assays at its Fire Creek gold Project in Nevada, from surface drilling. The drilling suggests possible extensions of the current mineral resource model.

Four reverse circulation (RC) holes were drilled as part of the Fire Creek hydrology study (see FIGURE 1). RC chips were logged, and samples collected on 5 ft intervals for assaying. Three of the four holes intercepted mineralization outside of the current mineral resource model that are in line with the underground workings. Grades from the surface drilling range from 16.3 g/t (0.47 opt) Au to 5.1 g/t (0.15 opt) Au. See Tables 2 and 3 below, for detailed sample results. Table 1 details significant assays and locations in relation to the mineral resource model at Fire Creek.

Mike Doolin, Klondex General Manager stated, "These intercepts continue to support our view that the Fire Creek project is significantly underexplored. The 2014 drill program is designed to follow up on new discoveries as well as extend the strike length and vertical extent of the current known mineralization, as we continue to unlock value at Fire Creek. Based on my personal experience, in these styles of mineral deposits, RC drill holes dilute and underestimate the grades. We expect that additional core drilling in these areas will clarify grades and widths."

The technical information contained in this press release has been reviewed and approved by Steven L. McMillin, CPG-11031 (American Inst. of Prof. Geol.), Chief Geologist for Klondex Mines Ltd., as a non-independent Qualified Person for the purposes of National Instrument 43-101.

RC sample size was monitored during drilling and kept to approximately 10-15kg. Reference chips were collected in standard chip trays for logging. Assays were performed by ALS Minerals in Reno, Nevada (an independent laboratory), under the supervision of Klondex staff. Fire Creek QA/QC protocols include insertion of standards, blanks, and duplicates approximately every 20 samples. Standard and blank samples use accredited reference material. Gold analyses were obtained via industry standard fire assay with atomic absorption finish. For samples returning greater than 10.00 g/t Au, a follow-up fire assay analysis with a gravimetric finish was performed.
