Klondex Receives Nevada State Approval for Fire Creek High-Grade Gold Underground Program

Klondex Mines Ltd. (TSX: KDX) announced today that it has been approved
for a Water Pollution Control Permit for its high-grade Fire Creek gold
deposit in North Central Nevada. The permit, which authorizes the
construction and operation of 'approved mining facilities in Lander
County,? will be issued by the Nevada Division of Environmental
Protection (NDEP) with an effective date of March 1, 2011.

Blane Wilson, President and COO of Klondex, commented, 'This is an
exciting and enormous milestone in the history of Klondex, as the NDEP
permit enables us to commence our underground operations next month. The
receipt of the permit would not have been possible without the
tremendous efforts of our Nevada staff and our permitting and
engineering consultants, Enviroscientists and Knight Piesold, as well as
the ongoing cooperation of the NDEP team.

'With the permit confirmed, we are full speed ahead in mobilizing our
mining contractor and Nevada team to commence our underground program,
which centers around an over 4,000 foot decline to reach the Main Zone
ore body. We look forward to reporting on progress of the decline in the
coming weeks.?

As of December 31, 2010 Klondex Mines had 36,544,089 shares issued and
outstanding, 41,319,089 shares on a fully diluted basis, and
