Klondex Mines Ltd. Clarifies Technical Disclosure, to Prepare Fire Creek Report

Klondex Mines Ltd. (TSX: KDX) ('Klondex? or the 'Company?) announced
today that as a result of a review by the British Columbia Securities
Commission (BCSC) Klondex is issuing the following news release to
clarify its disclosures regarding its Fire Creek property located near
Elko, Nevada. National Instrument 43-101 ('NI 43-101?) compliance issues
occur in the March 30, 2009 technical report 'Updated Report on the Fire
Creek Gold Property, Lander Co., Nevada? on SEDAR, (the '2009 Report?)
and were also present on the Company′s previous website, in corporate
presentations, and in investor relations materials.

New technical report being prepared

The Company′s annual information form of March 31, 2011 disclosed
material exploration activity since the 2009 Report and thereby
triggered the requirement under NI 43-101 to file a new technical report
concurrent with the AIF. Klondex intends to prepare and file the report
within 30 days.

Klondex clarifies that mineral resource estimates and information about
an underground bulk-sampling project, disclosed in the 2009 Report and
elsewhere, are unsupported by a compliant NI 43-101 technical report,
contrary to NI 43-101. Klondex cautions that the resource estimates, and
expected positive results of the bulk processing, should not be relied
upon until they have been independently verified and supported by an
updated independent technical report. If, because of the new report,
there are material changes in resource estimates, or other material
changes, the Company will promptly announce the results.

The Company′s 2011 PDAC presentation illustrated new models of veins
done by SRK Consulting. However, Klondex clarifies it has not received
new resource estimates, as defined by NI 43-101, since the 2009 report.

Retraction of economic analyses

On its website, in interviews or presentations available via its website
and incorporated by reference in the Company′s press release of November
5, 2010, the Company referred to results of preliminary economic
analysis of bulk sampling. The analysis included gold production
estimates, cash flow from bulk sampling, net operating cash flow,
operating margins, and economic analysis in terms of $/share based on
discounted gold metal value. The Company′s 2011 PDAC presentation and an
investor presentation on its website disclosed economic analysis
exceeding that of the initial bulk sampling program, including increases
in annual gold production in 2012 and 2013, and cash flow for a
longer-term mine plan based on a $1300 gold price. Klondex hereby
retracts all the referenced economic analyses. When the Company receives
an initial preliminary assessment as defined by NI 43-101, it will
promptly disclose the results and file a technical report as required by
NI 43-101.

Correction of noncompliant disclosure of mineral resources

Non-compliance issues on the Company′s prior website included one
instance where the inferred resource was termed an 'Inferred Mineral
Reserve?, and more frequent reference to mineral resources as ?ore? or
an 'ore body.? The use of reserve and 'ore? was inappropriate because
the Company has not completed a prefeasibility study, which is the
minimum requirement to demonstrate the economic viability implied by
such terms. The previous website and a corporate presentation disclosed
total resources by combining inferred resources with other classes,
contrary to NI 43-101. The Company has corrected its website resource
disclosure to comply with NI 43-101.

In those instances where the Company has retracted, revised, clarified
or updated previous disclosure, the Company advises readers not to rely
on such statements as they may continue to be found in the public domain.

Klondex is committed to bringing its technical and other disclosure into
compliance as quickly as possible and continues to dedicate significant
internal resources to prepare and verify the information contained in
its public disclosures.

Richard Kern, M.Sc. P. Geo, a Director of Klondex, is the Qualified
Person responsible for the accuracy of this news release in compliance
with NI 43-101.
