Klondex to Begin Drilling the West Zone

RENO, NV and VANCOUVER, BC--(Marketwired - Oct 31, 2013) - Klondex Mines Ltd. (TSX: KDX) (OTCQX: KLNDF), a Nevada gold exploration and development company, is pleased to announce a second underground diamond drill rig designated for exploration drilling will be at the Fire Creek gold project in the first week of November to follow up on previously identified exploration targets. The ongoing infill drilling program is currently drilling the northern extensions of the Joyce and Vonnie veins.

A three-phase exploration drilling program will initially target the West Zone mineralization approximately 105m (345 ft) west of the ramp, accessed from different points on the ramp. The West Zone was discovered while drilling for the recently completed secondary egress (see press release dated January 21, 2013). Klondex also drilled five holes west of the ramp from MB 5400, and 97.5m (320 ft) south from the secondary egress (see press release dated May 30, 2013).

Phase 1 drilling will take place from MB 5 to test the northern extension of mineralization, 29.2m (96 ft) north of the secondary egress drift (Figure 1). Twenty holes, totaling 5,212m (17,100 ft), are planned in this phase of drilling. Phases 2 and 3 of the drilling program, estimated at a total of 5,000m (16,422 ft), are intended to test the southern extension and tenor of the mineralization identified in earlier drilling from MB 5400.

The current infill program is designed to confirm the continuity of the Joyce and Vonnie veins to the north and to test a parallel mineralized structure east of the Vonnie vein. Five drill holes have been completed from MB 6; logging is in progress and assays are pending. An additional 13 holes are planned, totaling 2,472m (8,110 ft), to test for up-dip and down-dip continuity, as well as to better define the Joyce and Vonnie veins to the south (Figure 2).

Steve McMillin, Klondex Chief Geologist, commented, "This exploration program is designed to continue building our current mineral resource base, by drilling to the West, North and the Southern Main Zone, where we have identified high-priority drill targets. We believe these new targets will continue to demonstrate the high-grade nature of the deposit within close proximity to the current underground development."
