Updated Mineral Reserves And Resources For Fire Creek

VANCOUVER, BC - Klondex Mines Ltd. reported Mineral Reserve and Mineral Resource update for the Fire Creek mine located in northern Nevada. An updated technical report titled “Technical Report for the Fire Creek Project, Lander County, Nevada” dated February 5, 2018 with an effective date of November 30, 2017, has been filed on SEDAR. The Technical Report also will be filed on EDGAR and will be available on the Company’s website. Practical Mining LLC authored the report.

Fire Creek Mineral Reserve and Resource Highlights include an increase in total Measured, Indicated and Inferred Mineral Resource driven by the addition of the open pit (Mars Pit) resource (previously disclosed on December 21, 2017); Increase in total (underground and open pit) Measured and Indicated (“M&I”) Mineral Resource to 1.6M AuEq oz from 505k AuEq; A increase in total (underground and open pit) Inferred Mineral Resource to 1.6M AuEq oz from 507k AuEq; and underground Mineral Proven and Probable (“P&P”) Mineral Reserves of 229k AuEq oz.

Brian Morris, Senior Vice President, Exploration, said, “We had great success with our drill programs at Fire Creek in 2017. Results included significant growth of our indicated and inferred resource, driven by the addition of the Mars Pit. Furthermore, our underground resource is expanding to the northwest of existing mine workings. This area now contains approximately 30% of the total underground resource ounces. The Zeus target, discovered in 2016, now provides 100k gold ounces to our inferred resource estimate alone.” Morris continued, “With ongoing district-wide exploration and the 9-haulage development to the northwest in 2018, which will provide access for infill drilling, I fully expect to see continued growth of our underground and open pit resource at Fire Creek.”
