High-Grade Gold Veins Discovered East Of Main Zone In Klondex's 2009 Exploration Program

VANCOUVER (Business Wire) -- Klondex Mines Ltd. (TSX: KDX) (“Klondex” or “KDX”) today announced final results from its 2009 drilling campaign. The 2009 program included RC drilling of two IP anomalies, one of which yielded the discovery of two new veins. The IP anomaly targets were developed in a geophysical survey also conducted in 2009. KDX completed 15 holes totaling 20,221 feet (6,163 meters) within the Fire Creek project in 2009. The results are reported in the table below, and the drill plan showing all 2009 drill holes is posted at www.klondexmines.com. The bulk of the results for holes FC0901 through FC0905 were previously released.

2009 Geophysical Survey Identifies 15 Drilling Targets

In the summer of 2009 a new detailed, multi-method geophysical survey was run at Fire Creek (FC). The survey identified 15 untested anomalies that are drilling targets. Using a reverse circulation (RC) drill rig Klondex tested two of the anomalies. Drill holes FC0912RC through FC0915RC tested two anomalies located east of the Main vein zone. Holes FC0912RC and FC0913RC intersected two high-angle dikes with weakly anomalous gold values near the margins of the dikes below the first anomaly drilled.

RC Program Identifies Two New Veins

Hole FC0914RC intersected a broad zone of +0.03 oz/ton gold occurring between 925 and 1360 feet.Within this anomaly are two veins consisting of 3.5 feet (1.1 meter) true width of 0.26 oz/ton (9.1 g/t) gold and 0.76 oz/ton (25.9 g/t) silver and 3.5 feet (1.1 meter) true width of 0.26 oz/ton (9.1 g/t) gold and 0.18 oz/ton (6.3 g/t) silver.This new discovery is approximately 300 feet (91 meters) east of the nearest vein. FC0915RC was lost before reaching the mineralized horizon. Core drilling of the new discovery is planned in the spring of 2010.

Robert Sibthorpe, KDX's Technical Director, commented, “Our 2009 drilling program continued to expand the scope of mineralization at Fire Creek, an effort we will recommence in the spring. Drilling in 2009 extended Main zone mineralization further south and extended New North zone mineralization to the north, while also establishing a new vein system in the Eastern side of the Main zone. We also initiated an RC drilling program to more cost effectively test 15 anomalies identified in our 2009 geophysical program. Given our substantial property position and the success we have achieved, we are very optimistic about the potential to further extend the scope of the Fire Creek resource in 2010 and in the future.”

Main Zone Definition Drilling Yields 1.45 oz/ton Intercept

Holes FC0901 through FC0905 were targeted within the Main vein zone and were used to further define areas suitable for bulk sampling once underground work is initiated. These results included several +0.25 oz/ton gold valuesincluding 8.8 feet (2.7 meters) true width of 1.45 oz/ton (49.9 g/t) gold and 0.88 oz/ton (30.1 g/t) silver in hole FC0903.

Main and New North Zone Extension Drilling

Six of the remaining holes were targeted on possible extensions of the Main zone to the north and south and the north extension of the New North vein zone. FC0906 is the first hole to test the southernmost extension of Main, and it found two sub-grade veins worthy of further testing. FC0907 through FC0909 tested the northern extension of the Main zone. FC0907 and FC0908 both hit sub-grade veinswith FC0908 intersecting 29.8 feet (9.1 meters) true width of 0.08 oz/ton (2.6 g/t) gold.Located on the northernmost discovery at Main, this major fault zone will be tested further. FC0909 did not intersect any significant veining.

Drill holes FC0910 and FC0911 tested the northern extension of the New North zone. FC0910 was a 100-meter step-out and the first hole to explore this far north. The sub-grade vein intersected indicates the mineralized structure is still present, and a fence of holes are planned to further test this area. FC0911 was drilled to test directly west of a previous vein intercept and intercepted two sub-grade veins.

Klondex will continue testing additional geophysical anomalies in 2010 using an RC rig to identify vein zones and then following up with core drilling.
