VANCOUVER, BC--(Marketwired - November 20, 2017) - Klondex Mines Ltd. (TSX: KDX) (NYSE American: KLDX) ("Klondex" or the "Company") is pleased to provide the initial results from the 2017 surface exploration drill program at the Hatter Graben zone near its Hollister Mine ("Hollister") and report on progress made at the Midas mill regarding recovery of Hollister ore. Both Hollister and the Company's Midas mill are located in northern Nevada, USA.
Hatter Graben Surface Drilling Highlights: (see TABLE 1 for complete results)
Assays were received for the first five surface core holes at Hatter Graben. These are the first assays from an 11 hole drill program which was designed to infill drilling completed during 2008. The intent of this drill program is to develop an initial inferred resource at Hatter Graben. (Figure 1)
Drilling intersected several zones of multiple sub parallel veins similar to features encountered in 2008. Moreover, the results have extended the vein system down dip approximately 200 ft from the known mineralization. We now have a total of approximately 1,400 ft of vertical height of mineralized veins and the ongoing drilling is intended to further extend mineralization east along strike. Mineralization at Hatter Graben remains open in all directions. Drilling continues and is scheduled to be completed in early December. After which, the Company expects to receive final assays from the remaining six core holes by year end and publish an initial resource during the first quarter of 2018. (Figure 2)
Additionally, drill results have demonstrated that Hatter Graben is comprised of more competent rock compared to the Hollister mine. The host rock in the Hollister mine is clay rich and contains marginal ground conditions. The preferable ground conditions at Hatter Graben should allow for better vein development, superior dilution control and makes the more efficient long-hole stoping mining method a viable option.
Mr. Brian Morris, Senior Vice President, Exploration, said, "I am extremely encouraged by the initial results from our first five holes at Hatter Graben. At the onset, we had permitting delays which required us to drill our first three holes from the least optimal locations. We also experienced deviations on some of the initial holes which resulted in intercepting the vein system much deeper than the targeted elevations. Even with all of those challenges, we still encountered multiple veins similar to historical findings." Mr. Morris continued, "The most optimal drill sites are now fully permitted and drilling is ongoing from these locations. We are infilling and stepping to the east in the most desirable elevations where we fully expect robust results."
Midas Mill CIL Modification Update:
During the fourth quarter, the Company made a number of modifications to the new CIL circuit at the Midas mill in order to improve gold recoveries from Hollister ore. A plant trial, in which residual cyanide concentrations were reduced, has shown significant promise to improve gold recoveries and is being optimized. Longer term, the Company expects the gold recoveries from Hollister ore to average between 80% and 90%. In addition, the Company has gained efficiencies in the carbon handling circuit, which has reduced the time required to transition from CIL to Merrill Crowe, optimizing mill throughput.
Assays were performed by American Assay Laboratories of Sparks, Nevada, as directed under the supervision of Klondex staff. This organization is an ISO 17025 accredited independent laboratory.
