Surface Drilling at Klondex′s Fire Creek Gold Property in North Central Nevada Produces Positive Results

Klondex Mines Ltd. (TSX: KDX) today reported that its active 2011
surface drilling program continues to find new gold veins and to expand
the scope of the resource at its Fire Creek property in North Central
Nevada. Klondex has completed 16,947 feet of core and 18,040 feet of
reverse circulation (RC) drilling (see accompanying map). Twenty holes
have been completed to date, with assays received for 12 holes that are
reported below. The 2011 surface program is estimated to comprise 30-35
holes and approximately 56,000 feet of exploration drilling.

Highlights:

• 
  Fire Creek′s north Main Zone mineralization was extended by drill hole FC1104
  which intersected the strongest gold values yet encountered in this
  area. The intercepts included 0.298 oz/t gold over a true width of
  53.6 feet.
  
• FC1107RC intersected new veins between the Main and Far North
  Zones, including true widths of 4.2 feet averaging 0.389 oz/t gold and
  2.1 feet averaging 0.544 oz/t gold. Further testing of these new vein
  zones is planned for later this year.
  
• 
  New North Zone infill hole FC1112 intersected two gold veins of
  0.30 oz/t or more, including 4.1 feet averaging 1.41 oz/ton gold.
  

Klondex CEO, Blane Wilson, commented, 'Despite initial delays, our
surface exploration program is proceeding very well, with excellent
productivity and solid assays from the first set of holes that we are
reporting today. In these twelve holes, seven had values over 0.03
oz/ton gold and our team encountered nine gold intercepts greater than
0.29 oz/ton.

'We have already completed more surface drilling this year than in all
of 2010 or 2009, with two core rigs, two RC rigs and a directional core
rig currently on site. The directional rig is attempting to test feeder
faults crossing basement rocks well below identified mineralization.
This is the first time we have attempted to test the resource at depth.
It has been difficult but is now progressing well, and we should be in
position to test the targets later this month.?

Results

Gold and silver results, thickness, depth and target areas are shown in
the summary geochemistry table below. The accompanying map on the Klondex
website shows the new veins (+0.15 oz/t gold) in magenta and
gold bearing shear zones (0.03 to 0.15 oz/t gold) identified to
date in 2011, in gold.

2011 Exploration Program

Klondex′s 2011 drilling program, which began July 1^st, was
designed to test induced polarization (IP) anomalies as well as targets
associated with the known resource. The program has been revised and
expanded twice this year to include follow-up testing of new veins
discovered in 2010 as well as additional IP targets. IP anomalies remain
the best targeting tool for initial drilling, with several Fire Creek
anomalies remaining untested. Klondex is increasingly using more cost
effective RC drilling to initially test IP targets.

Approximately 30 currently permitted or nearly permitted holes are shown
on the accompanying map on the Klondex
website and represent future exploration targets for the 2011 and
2012 programs. In addition, approximately 30 more drill sites were
submitted for permitting in October, in an effort to provide a good
pipeline for future exploration expansion.

DRILL HOLE DESCRIPTIONS:

FC1101, drilled at the north end of Main Zone, intersected 85
feet of strong mineralization including 5 feet of 0.321 oz/t gold in a
new extension.

FC1102RC tested an IP anomaly northeast of the Main Zone, finding
no significant gold values.

FC1103 tested the north Main Zone west of the FC1104 test and
intersected two gold-bearing shears (810-885′ and 1220-1260′).

FC1104 extended north Main Zone veins to the north. The best vein
intercepts in this area are within a major gold-bearing shear over 100
feet wide (1230-1350′). A second strongly mineralized shear was
encountered near the bottom of the hole (1595-1636′).

FC1105RC tested an IP anomaly northeast of the Main Zone,
encountering no significant gold values.

FC1106RC tested the area between the north Main Zone and the Far
North Zone and an IP anomaly. The hole intersected two gold-bearing
shears within a wide structure with anomalous gold (1030-1120′).

FC1107RC also tested the area between the north Main Zone and the
Far North Zone and an IP anomaly, and intersected three +0.15 oz/t gold
veins in a new area.

FC1112, an infill hole drilled in the New North Zone, intersected
three +0.15 oz/t gold veins, two of which are +0.29 oz/t gold.

FC1113, an extension hole drilled in New North Zone, extended one
vein and two gold-bearing shears 50 meters at south end of resource.

FC1116RC, FC1117RC and 1118RC tested IP anomalies that may
represent deeper mineralization 1,000 meters north of the north Main
Zone. No significant gold values were encountered, but opal filled
structures indicate deeper drilling is needed.

About Klondex Mines Ltd. (www.klondexmines.com):

Klondex Mines is focused on the exploration and development of its 100%
owned Fire Creek gold deposit in North Central Nevada. Fire Creek is a
compelling gold mining prospect that is located near power,
transportation, mining infrastructure and several milling facilities.
Fire Creek′s updated mineral resource is reviewed in the table below.
For more information on the mineral resource estimates, please refer to
Klondex′s disclosure available at the SEDAR
website and here.

In addition to an active surface exploration program at Fire Creek, in
April 2011 Klondex initiated an underground exploration and development
program being pursued via an underground decline. The program is
designed to enable more cost effective in-fill drilling of its existing
resource from underground stations as well as to enable bulk sampling
for metallurgical testing of up to 120,000 short tons of material
(limited to 36,500 short tons per year). Bulk sampling is targeted to
begin in Q1 2012.

As of November 9, 2011, Klondex had 37.0 million shares issued and
outstanding and 43.8 million shares on a diluted basis.

Richard Kern (P.Geo), of Reno, Nevada, a qualified person as defined

technical information contained in this press release. All sample
preparation, including crushing, grinding and preparation of the assay
pulps, as well as sample analysis, was performed by ALS/Chemex in their
Nevada facilities.
