KLDX Klondex Mines Ltd. (delisted)

Klondex Mines Ltd. (TSX: KDX and OTCQX: KLNDF), a Nevada gold exploration company, today reported several intercepts of gold mineralization for the recently completed surface drilling program at its Fire Creek gold project in Lander County, Nevada. A total of 2,465 meters (8,086 feet) of core were drilled to extend ten holes that had been pre-collared with reverse circulation (RC) drilling; the results are summarized in Table 1.

Highlights:

All ten core holes encountered gold mineralization, with the best results including:

• 2,910 g/t (85 oz/ton) gold over 1.5 meters (4.8 feet) in hole FC12-11S (the same intercept also contained 5,960 g/t (174 oz/ton) silver).
• 97.9 g/t (2.9 oz/ton) gold over 0.4 meters (1.7 feet) in hole FC12-13S.
• 57.7 g/t (1.7 oz/ton) gold over 1.1 meters (3.7 feet) in hole FC12-21S.

Preliminary modeling indicates that the gold mineralization in FC12-11S occurs in a zone that is traceable and supports continuity for 152 meters (500 feet) along strike (Figure 1 - click here), the entire north-south extent of this core drilling program.

Paul Huet, Klondex’s newly appointed President & CEO commented, “This year’s exploration drilling at our Fire Creek gold project continued to identify gold mineralization, with FC12-11S returning grades that confirm the need for continued active exploration. We are currently developing an enhanced geologic model and updated resource estimate for Fire Creek and remain focused on unlocking the value of this deposit in the heart of Nevada gold country.”

Drilling Overview

The drilling program was designed to delineate gold mineralization in the Main Zone. Reverse circulation (RC) pre-collar holes were drilled from the surface to approximately 183 meters (600 feet) in depth and then extended by core drilling. Nine core extensions were completed to planned depths, and one was terminated early because of fluid infiltration between the hole and the underground workings. The program consisted of drill hole fans, as shown in Figure 1 (click here), with drill hole depths, azimuths and dips summarized in Table 2.

Geology and Mineralization

The highest assays from this program occur within the lower basalt rock package of the Tertiary volcanic sequence at Fire Creek and are associated with alteration envelopes of quartz-calcite-pyrite. The highest-grade intercepts reported here are associated with strongly silicified breccia cemented by quartz ± calcite ± sulfides.

Underground Development Program

As of September 21, 2012, Klondex’s underground development has totaled 1,253 meters (4,111 feet) of workings, with 949 meters (3,112 feet) of advance in the main decline. The decline was initiated in 2011 to enable underground exploration and in-fill drilling of the Main Zone mineralization. Klondex plans to continue development of the decline and workings parallel to strike, providing it access for exploration drilling in the near term, and future access for bulk sampling or full-scale mining activity. Klondex’s plans for the next 12 months are focused on the continuation of surface and underground exploration aimed at expanding both the scope of the resource as well as the understanding of the deposit’s geologic structure and profile. With this expanded knowledge, the Company feels it will be in a strong position to make development decisions for the project.
