The Vein is located 30.5 m (100 ft) west of the main ramp and 15.2 m (50 ft) east of the Karen Vein. The structure was identified as a target during the 2013 drill program, but was not included in the 2013 mineral resource estimate or subsequent Preliminary Economic Assessment, with respect to the Fire Creek project.

Based on current drilling, the known strike length of the Hui Wu Vein is 243.8 m (800 ft) and the known vertical dip extent is 76.2 m (250 ft), remaining open both north and south along strike, and up and down dip.

To date, 11 m (37 ft) of exploration development has been completed along strike of the Hui Wu Vein. Face samples range from 31.6 g/t (0.9 opt) Au to 395.9 g/t (11.5 opt) Au. The weighted average grade of samples taken from the Hui Wu Vein is 126.9 g/t (3.7 opt) Au over an average vein width of 1.1 m (3.5 ft). The fully diluted mined grade averaged 60.8 g/t (1.8 opt) Au over an average mining width of 2.2 m (7.4 ft). Assay results from samples from the Hui Wu Vein are summarized and detailed in Table 1, below.

Brent Kristof, Klondex Mines COO, commented, "The Fire Creek team has done an exceptional job continuing the drilling, sampling, and mapping program to identify yet another mineralized area. The Hui Wu Vein represents another growth opportunity to be targeted during our 2014 and 2015 exploration and development programs."

Channel assays were analyzed by SGS Minerals Services (Elko, Nevada) and Dave Francisco Lab (Fallon, Nevada), and drill assays were analyzed by ALS Chemex (Reno, Nevada) and American Assay Labs (Sparks, Nevada) under Klondex staff supervision. These are all independent laboratories. Sampling a given face is conducted after the face location has been washed, measured, mapped in detail and photographed. Continuous rock-chip channel samples are then collected by Klondex staff directly into 11" x 17" sample bags from the footwall, vein, and hanging wall. Individual samples are defined by geology and do not exceed 3′ in length in order to better define the location of grade. Salient features including sample number, channel length, location on face, rock type, and alteration are documented. Blank samples are inserted into the sample stream to help monitor QA/QC of the labs. Channel samples and respective assays are loaded into an Access database, and ultimately visualized in Vulcan where they are correctly located in space and utilized in resource estimation.
