Klondex Intercepts 767.0 g/t (22.4 opt) Gold Over 0.6m

ELKO, NV and VANCOUVER, BC--(Marketwired - Jun 18, 2013) - Klondex Mines Ltd. ( TSX : KDX ) ( OTCQX : KLNDF ), a Nevada gold exploration and development company, today reported the results of seven drill holes from drill station 9 (Table 1) at its Fire Creek gold project in Nevada. A new mineralized structure was identified running parallel and to the west of the Joyce Vein (Figure 1) and (Figure 2) that included an intercept 869.0 g/t (25.3 opt) gold over 0.12m (0.4ft) in drill hole FC-13-069U.

Klondex Mines' Fire Creek project General Manager, Mike Doolin, stated, "Today's announcement further supports our belief that Fire Creek is an under-explored asset. We continue to further demonstrate continuity as the drill program moves forward. We have decided to delay our updated mineral resource estimate in order to incorporate recent underground drilling results. We anticipate that this will push out the completion of the updated mineral resource estimate by approximately one month, from late June to the end of July, but will allow us to develop a more current resource model."

Infill Drilling from Station 9 (Figure 1) and (Figure 2) A drill fan totaling nine holes has been drilled to the east from drill station 9 to test the continuity, height and width of the Joyce and Vonnie Vein structures from the 5400 cross cut. The drill holes encountered mineralization consistent with the Joyce and Vonnie Veins. Drilling of these structures has demonstrated an average thickness of 1.0-1.5m (3.3-4.9ft) over a strike length of 115m (377.3ft) and a possible vertical extent of 167.6m (550ft). Both veins remain open along strike and at depth, restricted only by the amount of drilling data.

Two drill holes intercepted a mineralized structure -- between the drill ramp and the Joyce Vein -- which bears similar mineralization but was not apparent in the 5400 cross cut. FC-13-062U intercepted 1.5m (5.0ft) of 70.6 g/t (2.1 opt) gold and was 12-13m (38-43ft) away from the drill station, and FC-13-069U intercepted 869.0 g/t (25.4 opt) gold over 0.12m (0.4ft) and was located 7.9m (25.8ft) from the drill station.

2013 Underground Infill Drill Program Overview (Figure 3) Klondex's 2013 infill drill program has now completed 27 underground drill holes for a total of 3,523 m (11,558 ft) at the Fire Creek project.

Drill station 9: The planned 14 drill holes are complete; five holes to the west and nine holes to the east. All drill holes to the west encountered mineralization that may connect to the vent raise mineralization along northwest trending structures. The drill holes are located 50.3m (165 feet) west of the vent raise, suggesting a potential new zone strike length of at least 98m (320ft) south from the vent raise access, located approximately 105m (345ft) west of the ramp (see May 30, 2013 news release) .

Drill station 1 (Figure 3) : Seven east-directed holes have been completed, and logging is in progress with assays pending. Drilling from station 1 east of the ramp is testing the extension and continuity of mineralization of the Vonnie and Joyce Veins in the 5400 cross cut to the north, and in drill hole FC12-029U, 16.6 g/t (0.48 opt) Au over 13.0m (42.8ft) to the southwest (see April 9, 2013 news release) .

Drill station 2 (Figure 3) : Klondex is now drilling from station 2, where six of nine planned holes have been completed.

Samples cited in this news release were obtained from in-fill drilling by independent contractor American Drilling of Spokane, Washington under the direction of Klondex staff. Assays were determined by ALS Minerals of Reno, Nevada, an independent analytical laboratory. Sample preparation is conducted in Elko, Winnemucca, or Reno facilities, and fire-assay analytical work is conducted in Reno. Standard fire assays with a 30g charge are performed on all samples up to 10 g/t, and then gravimetric assays are conducted on samples with 10g over-limit assays. Select metallic-screen assays are then conducted by re-sampling the coarse reject using criteria such as clustering of assays, proximity to veins, and mineralized veins. Multi-element ICP samples are collected on 20ft composites and on individual samples in mineralized rock. For QA/QC monitoring, standards and blanks are inserted approximately every 20 samples using accredited reference material. Duplicates are generated by ALS by splitting the sample immediately in advance of the duplicate and assaying one split. Standard sample performance is frequently monitored using statistical spreadsheets provided by Micon International.
