IDM Mining (TSXV:IDM) (“IDM” or the “Company”) is pleased to announce assays from an additional 10 underground core holes completed at the Red Mountain gold project (“Red Mountain” or the “Project”), located 15 km east of Stewart, BC. These results are from the ongoing Phase I drilling program.
Highlights from the recent underground drill results (capped) include:
  • U16-1194: 23.13 meters true width at 5.81 g/t Au and 16.11 g/t Ag; AV zone infill and metallurgical hole
  • U16-1200: 7.44 meters true width at 12.18 g/t Au and 19.04 g/t Ag; JW zone infill
  • U16-1202: 17.81 meters true width at 6.45 g/t Au and 60.70 g/t Ag; JW zone infill and metallurgical hole
  • U16-1204: 15.43 meters true width at 10.97 g/t Au and 9.18 g/t Ag; Marc Zone infill and metallurgical hole
  • U16-1205: 8.00 meters true width at 20.29 g/t Au and 68.74 g/t Ag; Marc Zone infill and metallurgical hole

This batch of drill results are primarily infill holes to gather data for ongoing Feasibility Study work, including metallurgical, geotechnical and hydrological data, as well as to potentially upgrade inferred and indicated resources to higher categories.
These results confirm the substantial widths and robust grades at Red Mountain,” said Robert McLeod, President and CEO of IDM Mining. “Our underground drill crews at Red Mountain are currently wrapping up the final resource expansion holes from the 2016 program, with additional assay results to be announced through the remainder of the year, including surface drilling from Lost Valley, 141 and Brad Zones.
Drill holes U16-1194, and 1196 tested a thick portion of the AV zone, infilling a 50 meter gap between historic holes. Material was also collected for metallurgical testwork and for geotechnical and groundwater hydrology. U16-1194 intersected 23.13 meters true width averaging 5.81 g/t Au and 16.11 g/t Ag, with U16-1196 intersecting 22.0 meters true width averaging 3.05 g/t Au. These holes correlate well with estimated grade and thickness of the AV zone in this area of the deposit. Drill hole U16-1195 tested a gap in the narrower, down dip tail to the AV Zone.
The primary purposes of drill holes U16-1197, 1198 and 1199 were for geotechnical and groundwater hydrology studies; in particular, to confirm the location of a post-mineralization strike-slip fault that separates the AV and JW zones and to assess overall host rock competency.
On section 1550N, drill holes U16-1200 and 1202 targeted inferred resources of the JW zone and to collect material for metallurgical testwork. U16-1200 intersected 7.44 meters true width averaging 12.18 g/t Au and 19.04 g/t Ag including 2.49 meters true width averaging 26.63 g/t Au and 23.48 g/t Ag. Drill hole U16-1202 intersected 17.81 g/t Au averaging 6.45 g/t Au and 60.70 g/t Ag including 3.48 meters true width averaging 12.98 g/t Au and 181.15 g/t Ag. High grade silver was encountered in this intercept, which extends the JW zone further updip from historic intercepts.
Drill holes U16-1204 and 1205 were infill and metallurgical holes targeted the north end of the Marc Zone, adjacent to the fault that offsets mineralization to the AV zone further north. U16-1204 intersected 15.43 meters true width averaging 10.97 g/t Au (capped) and 9.18 g/t Ag; this included 0.80 meters averaging 99.50 g/t Au and 72.30 g/t Ag as well as 1.00 meters averaging 101.50 g/t Au and 24.40 g/t Ag. These high grade gold values were capped to 55.00 g/t Au.

About Red Mountain
The 17,125 hectare Red Mountain gold project is located in northwestern BC, 15 km northeast of the town of Stewart. IDM is advancing a Feasibility Study for a high-grade underground gold mine, which envisions primarily bulk underground mining methods. Additionally, the Project is advancing through the Provincial and Federal Environmental Assessment Process, with ongoing consultation with the Nisga’a First Nations government.
On April 4, 2016, the Company announced an updated mineral resource estimate reported at 3.0 g/t Au cut-off for the Red Mountain gold project.

Red Mountain is a porphyry-related hydrothermal gold system, located in the Stikine terrain. Gold mineralization is associated with, and partially hosted within an early to mid-Jurassic multi-phase intrusive complex, with associated volcanic and volcaniclastic rocks and sediments. Many gold mineralized zones occur on the property, including five mineralized zones with established resource estimates. The five mineralized zones (Marc, AV, JW, 141 and 132) have been folded, and are often separated by dip-slip fault zones. The mineralized zones vary in orientation from shallow to steeply dipping and are generally tabular. The Marc, AV and JW Zones vary in widths from one to forty meters, averaging about fifteen meters in thickness. Gold and silver mineralization is associated with stockworks, disseminations and patches of coarse grained pyrite, surrounded by a pyrrhotite/sphalerite halo. Alteration facies includes strong quartz-sericite alteration.
