NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN
THE UNITED STATES


As a result of a review by the British Columbia Securities Commission, Klondex
Mines Ltd. (TSX:KDX)(OTCQX:KLNDF) ("Klondex" or the "Company") is issuing the
following news release to clarify its disclosure with respect to the Company's
Fire Creek project (the "Fire Creek Project") and its Midas mine and mill (the
"Midas Project"). The Company advises that the clarified disclosure is being
made in connection with its previously announced filing of a preliminary short
form prospectus.


All non-compliant technical disclosure has been removed from the Company's
website and social media pages controlled by the Company in respect of the Fire
Creek Project and the Midas Project in accordance with National Instrument
43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Specifically,
the Company has removed from its website and from social media pages controlled
by the Company a webcast presentation dated May 8, 2014 from the Denver Gold
European Gold Forum (the "Webcast"). 


Midas Project

In the Webcast, the Company made certain statements regarding the "reserves
remaining" at the Midas Project. These statements related to historical
reserves, as disclosed in the technical report titled "Technical Report for the
Midas Mine and Mill, Elko County, Nevada", dated March 31, 2014 (effective
January 31, 2014), as amended, prepared by Mark Odell, P.E. and Adam Knight,
P.E. of Practical Mining LLC, Michele White, C.P.G. of All One River, LLC and
Karl Swanson, M.Eng., SME, AusIMM, Independent Mining & Geological Consultant
(the "Midas Report"). Readers are advised that the reserves the Webcast referred
to comprise a historical estimate and that a qualified person has not done
sufficient work to classify such historical estimate as current mineral
reserves. The Company is not treating the historical estimate as current mineral
reserves. Further, statements made in the Webcast regarding operations underway
at a "new high-grade ore pod" at the Midas Project represent management
objectives and the Company hereby retracts the statement with respect to the
economic viability of additional veins for which mineral resources have not been
established in accordance with NI 43-101.


The Company notes that a production decision at the Midas mine was made by
previous operators of the mine, prior to the completion of the acquisition of
the Midas Project by Klondex and Klondex made a decision to continue production
subsequent to the acquisition. This decision by Klondex to continue production
and, to the knowledge of Klondex, this production decision made by the previous
operator were not based on a feasibility study of mineral reserves demonstrating
economic and technical viability prepared in accordance with NI 43-101. Readers
are cautioned that there is increased uncertainty and higher risk of economic
and technical failure associated with such production decisions."Readers are
advised to refer to the full text of the Midas Report, which is available for
review under the Company's profile on SEDAR at www.sedar.com. 


Fire Creek Project

Certain oral statements contained in the Webcast regarding the "robustness" of
the preliminary economic assessment in respect of the Fire Creek Project (the
"Fire Creek PEA") represented the opinion of management and were not intended to
suggest that there is certainty that the Fire Creek PEA will be realized. The
Company hereby retracts the oral statements made in its Webcast presentation
regarding the "de-risking" of the Fire Creek Project and reminds readers that
the Fire Creek PEA is preliminary in nature and includes inferred mineral
resources that are considered too speculative geologically to have the economic
considerations applied to them that would enable them to be categorized as
mineral reserves. There is no certainty that the Fire Creek PEA will be
realized. Mineral resources that are not mineral reserves do not have
demonstrated economic viability. 


The Company is in the process of updating the slide presentation relating to the
Webcast to comply with the requirements of NI 43-101, including the requirements
to (i) disclose categories of mineral resources at the Fire Creek Project
separately, (ii) disclose the quantity and grade or quality of each category of
mineral resources, and (iii) include a statement that mineral resources that are
not mineral reserves do not have demonstrated economic viability. For detailed
information regarding mineral resources at the Fire Creek Project, readers are
advised to refer to the full text of the Fire Creek PEA contained in the
technical report titled "Preliminary Economic Assessment of the Fire Creek
Project, Lander County, Nevada", dated June 13, 2014 (effective date of January
31, 2014), as amended, prepared by Mark Odell, P.E., Laura Symmes, SME and Sarah
Bull, P.E. of Practical Mining LLC and Karl Swanson, M.Eng., SME, AusIMM,
Independent Mining & Geological Consultant, which report is available for review
under the Company's profile on SEDAR.


Readers are advised not to rely on retracted information, including information
contained in the Webcast, to the extent that such information continues to be
available in the public domain.
