Dec. 13, 2010 (Business Wire) -- Klondex Mines Ltd. (TSX: KDX), announced that to date its 2010 exploration drilling program has identified six previously unknown gold vein structures and intercepted several new gold bearing shears at its Fire Creek property in North Central Nevada. Today’s results are based on assays received from 11 of 15 completed holes as surface drilling continues. Klondex has completed 9,573 feet/2,198 meters of core and 12,710 feet/3,874 meters of RC drilling. Six of 11 holes are step out drilling to test known IP anomalies while five holes were in-fill, testing known mineralization. Results are reviewed below and on a drill plan map on the KDX website.

Klondex’s 2010 surface drilling program has identified a new vein between the Main and Far North Zones (FC1007RC), two new veins within the Far North Zone (FC1003B), strong veining near the north end of the New North Zone (FC1004) and extended the Main Zone vein system 100 meters to the south (FC1012RC, FC1013RC, FC1016). Follow-up drilling of the new veins and vein shears will be required to further demonstrate their significance. Results from this year’s program, as well as last year’s productive 15-hole program (totaling 20,221 feet/6,163 meters) are not yet included in KDX’s 43-101 resource, last updated in March 2009.

Blane Wilson, President and COO, commented: “Surface drilling at Fire Creek continues to be very productive, delivering new veins and intercepts while also growing the geographical scope of the Fire Creek resource. We continue to balance our exploration efforts with in-fill core drilling of known mineralized areas with the testing of IP targets through RC drilling. Given the onset of winter weather at Fire Creek, we expect to suspend further RC drilling in the near term but plan to continue our core drilling into late January or beyond.

“We expect to initiate underground operations in 2011, though surface exploration will remain a priority for the Company. Our current surface exploration program covers four square miles, and we are confident it can lead the way to expanding our resource and additional underground development.”

DRILL HOLE DESCRIPTIONS:

FC1001 Drilled above and 200 feet west of FC0914RC intercept (two intercepts of +9.0 g/t Au). Crossed shear zone 1260-1350 feet with gold up to 0.9 g/t.

FC1002B Tested east and 200 feet below FC0914 intercept. Shear zone 1190-1360 feet with gold high of 2.6 g/t.

FC1003B Drilled untested western portion of Far North vein system. A single vein hit to the north became 3 strong veins in this hole within a 230 feet thick zone running 1.6-1.8 g/t gold.

FC1004 Drilled near the northern end of the New North Vein system. A strong vein was intersected 6.5 meters true width averaging 9.95 g/t gold or 1.1 meters assaying 33.00 g/t gold.

FC1005B Drilled to target northern Main. The hole intersected gold-bearing shears at 800-900 feet (in Latite tuff), 1150-1200, 1310-1350 and 1430-1460 feet. The gold high is 3.1 g/t.

FC1006RC This hole targeted an IP anomaly 1300 feet (400 meters) north of Main. A shear zone with anomalous gold up to 0.7 g/t was intersected from 670 to 710 feet.

FC1007RC This hole targeted an IP anomaly over northern Main west of where FC1006RC tested. This hole discovered a new vein and 3 gold bearing shears located between northern Main and Far North (950-1020, 1070-1110, 1320-1370 feet). The vein runs 5.14 g/t gold over a true width of 1.1 meters.

FC1010RC This hole was drilled to test an IP anomaly over east Main. It intersected a mineralized shear bordering a basalt dike from 1320-1460 feet with a high of 1.4 g/t gold.

FC1012RC Drilled as part of a two hole fence testing the south extension of Main and an IP anomaly to the east, this hole intersected a wide gold bearing shear zone from 400-580 feet. High gold for the interval is 0.8 g/t.

FC1013RC The second of the 2 hole fence with FC1012 this hole was drilled from further west. The hole intersected one vein (1.1 meters true width of 4.79 g/t gold) within a gold bearing shear from 560-660 feet. This extends the Main vein system a further 50 meters south from FC1016.

FC1016 Drilled at 45 degrees the hole intersected 28 meters true width of 1.88 g/t gold from 360 to 490 feet depth. Within this is an intercept of 4.3 meters true width of 4.99 g/t gold. This hole extends the Main vein zone 50 meters south.

After giving effect to the private placement, as of November 10, 2010 Klondex Mines had 36,544,089 shares issued and outstanding, 41,319,089 shares on a fully diluted basis, and approximately CDN $9 million in cash.
