Klondex Discovers a New “West Zone” with Significant Visible Gold Mineralization and 123.9 Grams/Tonne (3.6 oz/ton) Gold Over 1.5 Meters (5 feet)

Klondex Mines Ltd. (TSX: KDX or OTCQX: KLNDF), a Northern Nevada gold exploration and development company, announces the discovery of new gold mineralization at its flagship Fire Creek project. The discovery (Figure 1 click here) is approximately 165 meters (540 feet) west of the A-Vein mineralization, which forms part of the Main Zone, and represents a new unexplored zone. Klondex intersected 123.9 grams/tonne gold (3.6 oz/ton) over 1.5 Meters (5 feet) while completing a geotechnical drill hole for the design of the planned vent raise. Klondex also encountered visible gold mineralization in three locations in the area: on the left rib of the nearby drift (Figure 2), in a drill hole at the base of the access ramp 5370-RM (Figure 3), and in the geotechnical hole, approximately 6 meters (20 feet) above the access ramp (Figure 4) Click here for Figures 2, 3 & 4.

Paul Huet, CEO of Klondex, commented, “We are very excited by this new discovery at Fire Creek.. A discovery of this nature demonstrates that Fire Creek remains under-explored and that ongoing exploration could lead to other zones providing potential growth for Klondex.

“We have designed our underground in-fill drilling program to tighten the drill spacing in the Main Zone to include 16 easterly drill fans of three to four drill holes each, totaling 9,754 meters (32,000 feet). This will refine our resource model with additional data and hopefully identify new areas of mineralization. As a result of the new gold mineralization found in the vent raise access we will be expanding our program to the west as part of Phase 2”.

Steve McMillin, Chief Geologist for Fire Creek, added, “This new discovery is very exciting for Klondex as it occurs in an area with very little previous drill information. The find was unexpected and has the team discussing expanded and more comprehensive future drilling at Fire Creek. It occurs within a very large area of alteration, at least 27 meters wide (90 feet) and also has a higher silver content than we have seen elsewhere at Fire Creek.”

Sample results cited in this news release were obtained through rib samples performed by Klondex geologists and via a geotechnical hole drilled by independent contractor American Drilling under the direction of Klondex staff. Assays were determined by ALS Minerals of Reno, Nevada and Inspectorate America Corporation of Sparks, Nevada, both independent analytical laboratories. Klondex is not yet able to determine true widths.
