Klondex Update on Rice Lake Development Activities

VANCOUVER, BC--(Marketwired - April 14, 2016) - Klondex Mines Ltd. (TSX: KDX) (NYSE MKT: KLDX) ("Klondex" or the "Company") is pleased to provide an update on the Company's exploration and development activities at its Rice Lake Mine in Manitoba, Canada. The drill results summarized below were conducted by a prior owner of the Rice Lake Project. The Company intends to follow-up on the 15 hole drill program later this year.  A summary of the results of this prior drill program is set out below.  

Rice Lake Drilling Highlights from Q4 2014:

• 644-14-009: 0.15 opt Au over 14 ft, or 5.1 g/t over 4.3 m (Hanging Wall)
• • Including 0.30 opt Au over 5.3 ft, or 10.3 g/t over 1.6 m
• 644-14-011: 0.59 opt Au over 2.3 ft, or 20.4 g/t over 0.7 m (Hanging Wall)
• 644-14-016: 0.70 opt Au over 4.2 ft, or 24.1 g/t over 1.3 m (Foot Wall),
  and 0.53 opt Au over 7.3 ft, or 18.1 g/t over 2.2 m (91 Vein)
• 644-14-017: 0.42 opt Au over 10.0 ft, or 14.3 g/t over 3.0 m (Foot Wall)
• • Including 0.76 opt Au over 4.3 ft, or 26.0 g/t over 1.3 m
• 644-14-018: 0.43 opt Au over 22.2 ft, or 14.8 g/t over 6.8 m (Foot Wall)
  • Including 0.57 opt Au over 16.4 ft, or 19.6 g/t over 5.0 m
• 644-14-019: 0.54 opt Au over 17.3 ft, or 18.4 g/t over 5.3 m (Foot Wall)
• 644-14-021: 1.89 opt Au over 14.0 ft, or 64.7 g/t over 4.3 m (Foot Wall),
  and 0.53 opt Au over 3.3 ft, or 18.1 g/t over 1.0 m (91 Vein)

A total of 15 holes totaling 6,485 ft (1,977 m) were drilled during the fourth quarter of 2014 by San Gold Corp. from the 6440 drill station.  These holes were targeting the down-dip extension of the 91 vein. This drilling identified the potential for a new vein in the footwall of the 91 vein adjacent to the 24 level incline.  Moreover, an additional mineralized structure was intersected in the hanging wall of the 91 vein.  This mineralization occurred where northeast and northwest structures intercept the San Antonio Mining unit (SAM) which is the host rock to much of the historic mining at the Rice Lake Mine.  Drilling is planned for later this year to follow up these high grade intercepts.

Project development activities continue to advance and are on schedule and within budget.  

Project Development Highlights:

• Rice Lake Project has completed 83 days without a Loss Time Incident.
• The notice to recommence mining and milling operations was approved by the Director of Manitoba Mineral Resources in March, 2016.
• Shaft Project Complete - 100% of the guides have been replaced.
• Track Repair Ongoing - Approximately 1,500 of track has been ditched and repaired at the 2600 level; project is ~55% complete.
• Initiated testing of narrow vein long hole design to reduce dilution.
• New underground shop and new gear storage cut-outs are 80% complete.
• Initial metallurgical testing on existing tailings indicate the tailings can be processed through the existing mill flow sheet.

Mr. Paul Huet, President and CEO commented, "Our progress at the Rice Lake Mine has proceeded better than expected. The results of the Q4 2014 drill program noted above are very encouraging and suggest the opportunity for new high grade discoveries at Rice Lake." Mr. Huet continued, "Our progress in refurbishing the track and the shaft is on budget and on schedule and we are excited about the successful testing of long hole stoping at the mine.  We continue to expect to be in a position to announce a production decision in the second half of this year, and we remain grateful to be part of such an exceptional and supportive mining community in Bissett."

Underground drill core samples were assayed on site in the then owner's assay lab using the fire assay method with an AA and gravimetric finish.  The quality control and assurance program included the insertion of standards, the retention of pulps and rejects, and spot checks utilizing independent labs including TSL Laboratories in Saskatoon, Saskatchewan and Accurassay Laboratories in Thunder Bay, Ontario.  The core lengths are actual lengths as drilled and were not adjusted for the true width of the mineralized zones.
