Klondex Initiates Step-Out and Infill Drilling of High Grade Gold Targets in Nevada

Klondex Mines Ltd. (TSX: KDX), is very pleased to announce details on
its summer drill program. Blane Wilson commented, 'We are incredibly
excited to initiate drilling on some of the most prospective targets
identified by last year′s exploration program. Our Multi-Method
Geophysical Survey completed last summer indicated several new targets
that may offer the possibility of an increase to our 43-101 compliant
resource. We look forward to reviewing the data generated with this
summer′s program.?

Drilling will commence under the direction of Richard Kern and will
focus on step-out drilling through the use of RC and Core. This program
will enable KDX to begin the process of including the southern extension
in our underground development plans and also work towards adding gold
ounces to the already impressive 1.6 million indicated ounces and 0.5
million inferred ounces. In an effort to complement our underground
plans we also plan to initiate some strategic infill drilling. This will
allow us to show vein continuity and generate further metallurgical
testing as we prepare for underground mine development later this year
and initial bulk sampling in 2011. We anticipate the first rig will
arrive on site June 28^th and commence work shortly thereafter.

A map showing the planned holes is available at www.klondexmines.com/s/News.asp.
