IDM Mining Expands Underground Drilling Program at Red Mountain Gold Project; Adds Third Drill

IDM Mining (TSXV:IDM, OTCQB:IDMMF) (“IDM” or the “Company”)  announces that the ongoing underground drilling program at the advanced-stage Red Mountain Underground Gold Project (“Red Mountain” or the “Project”), located east of Stewart, BC has been expanded with a third drill rig added.  With efficient and encouraging drilling to-date, an additional 5,400 meters have been added; 13,000 meters in over 54 holes are now planned.  The Company has staged the drilling program from a winterized camp and shop facility located adjacent to the underground workings.

Exploration drilling during the 2018 program has been testing multiple extensions to various zones at Red Mountain, including: a near-surface synform between the Marc and 141 Zones; the northern and western extensions to the Smit and JW Zones; a projected high-grade connection between the Smit and 141 Zones; and the northern and eastern extensions to the SF Zone antiform.  Additionally, drilling has been targeting the conversion of inferred resource to measured and indicated classification, primarily within the Smit and SF Zones.  Multiple exploration holes are also planned to test previously undrilled areas located to the south and east of the resource area.

“Our new geological interpretation, that has connected zones previously thought to be separate mineralized structures through large-scale folding, is being validated.  Coupled with safe and efficient drilling by IDM’s site team and our contractors including: Morecore Drilling, Matrix Camp Services, Yellowhead Helicopters and Adapt Mountain Safety Services, our program has been significantly under budget and ahead of schedule,” said Robert McLeod, President and CEO of IDM Mining.  “With increased confidence in the continuity of the extensions of the mineralized horizon at Red Mountain, we are looking forward to exploring new, undrilled targets in addition to expanding known zones.”

It is expected that the underground drill program will be completed by mid-December 2018.

QA/QC and Qualified Person

Samples for the 2018 exploration program are cut in-half with a diamond saw after logging by experienced geologists and technicians, placed in sealed bags and shipped to MS Analytical Labs in Terrace, BC for sample preparation, with pulps subsequently shipped to Langley, BC for gold and multi-element ICP analysis. A Quality Control/Quality Assurance program including the insertion of Standards and Blanks has been implemented, as well as rigorous chain of custody documentation.  The 2018 Exploration Program is performed under the supervision of Andrew Hamilton, P.Geo, Senior Geologist for IDM Mining Ltd. and Robert McLeod, P.Geo, President and CEO of IDM Mining Ltd; both are ‘Qualified Persons’ under NI 43-101.  Mr. McLeod has reviewed and approved the technical content of this release.
