Klondex Announces New Discovery at True North

Klondex Mines Ltd. ( TSX: KDX) (NYSE MKT: KLDX) (“Klondex” or the “Company”) is pleased to provide an update on underground drilling at its True North Gold Mine (“True North”) in Manitoba, Canada. The following drill results are not included in the mineral reserve and mineral resource estimates released on September 12, 2016. The Company expects to provide an updated mineral reserve and mineral resource update for True North in the second quarter of 2017.

True North Gold Mine Drilling Summary: (FIGURE 1)
Assay results have been received for 18 underground drill holes totaling 16,660 ft (5,078 m). These holes targeted a significant down dip extension of the 007 zone, the down dip extension of the 710 zone at the 32 Level, the up and down dip extensions of the 711 zone at the 24 Level and the down dip extension of Cohiba.
007: (FIGURES 2 and 3)
Four exploration holes were drilled from the 26 Level targeting the down dip extension of the 007 zone into the historic San Antonio Mine (SAM) unit. The SAM unit produced approximately 1.5 million ounces of gold throughout its history. This target was generated by projecting the 007 structure so that it extended out of the Shoreline Basalt into the historically most productive SAM unit. The first drill hole, 26-16-001 successfully intersected the down dip extension of the 007 structure approximately 1,775 ft (541 m) east of the current 26 Level workings and 2,135 ft (651 m) below the 007 decline. Assays from the remaining three holes are pending.
Down Dip Extension of 710:
Assay results were received for the first six holes testing the down dip extension of the 710 vein on the 32 Level. All six holes successfully intersected the mineralized structure in the targeted area confirming continuity of the 710 zone over 600 ft (183 m) down dip, which remains open at depth. Additionally, drill hole 32-16-006 intersected a new mineralized structure in the hanging wall. Drilling is ongoing and subsequent assays are pending.
Up and Down Dip Extension of 711:
Assay results were received for the final two holes of the 711 down dip exploration program as well as the first six holes from the 711 up dip exploration program. Results from both programs suggest that the mineralization of the 711 zone extends both up and down dip and remains open in both directions.
Cohiba:
The Company is reporting the final three holes of the 2016 Cohiba down dip extension drill program. All three holes intersected mineralized material in the Cohiba structure suggesting the Cohiba zone remains open at depth and along strike.
Mr. Brian Morris, Vice President, Exploration said, “These results from True North’s exploration drilling program are extremely important; the team’s exploration model and understanding of local vein systems have already lead Klondex to a significant new discovery which has the potential to add substantial resource growth at True North. This new discovery continues to suggest that the True North district remains under explored and has the potential to be much larger than what we understand today.” Mr. Morris continued, “Moreover, not only are we continuing to extend the mineralization up and down dip in the 710 and 711 zones, we are consistently identifying new targets in close proximity to existing infrastructure.”
Assays were performed by TSL Laboratories, an ISO 17025 accredited independent laboratory, and samples were collected and shipped under the supervision of Klondex staff.

Cautionary Note Regarding Forward-looking Information
This news release contains certain information that may constitute forward-looking information or forward-looking statements under applicable Canadian and United States securities legislation (collectively, “forward-looking information”), including but not limited to the exploration potential at the True North Gold Mine, the timing of an updated mineral reserve and mineral resource update for True North and future exploration and production plans of Klondex. This forward-looking information entails various risks and uncertainties that are based on current expectations, and actual results may differ materially from those contained in such information. These uncertainties and risks include, but are not limited to, the strength of the global economy; the price of gold; operational, funding and liquidity risks; the degree to which mineral resource estimates are reflective of actual mineral resources; the degree to which mineral reserve estimates are reflective of actual mineral reserves; the degree to which factors which would make a mineral deposit commercially viable are present; the risks and hazards associated with underground operations; and the ability of Klondex to fund its substantial capital requirements and operations. Risks and uncertainties about the Company’s business are more fully discussed in the Company’s disclosure materials filed with the securities regulatory authorities in Canada and United States available at www.sedar.com and www.sec.gov, respectively.

Cautionary Note to U.S. Investors Regarding the Use of Mining Terms
This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. All resource and reserve estimates included or referred to in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101″). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the mineral reserve disclosure requirements of the U.S. Securities and Exchange Commission (the SEC”) set out in Industry Guide 7. Consequently, reserve and resource information contained in this news release is not comparable to similar information that would generally be disclosed by U.S. companies in accordance with the rules of the SEC.
