IDM Mining Commences Underground Resource Expansion and Infill Drilling Program at Red Mountain Gold Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 11, 2016) - IDM Mining Ltd. (TSX VENTURE:IDM) ("IDM" or the "Company") is pleased to announce that ongoing rehabilitation of the underground equipment and workings at the Red Mountain gold project and the timely receipt of provincial permits has enabled the commencement of drilling. This work is another step in the steady advancement of the Red Mountain Project towards a Bankable Feasibility Study (BFS) and ultimate Final Investment Decision (FID) planned for 2017.

"We are fortunate to have access to the Red Mountain deposit with an existing production-sized underground decline, plus a fleet of mining and support equipment," said Rob McLeod, President and CEO of IDM Mining. "The excellent ground conditions have enabled a straightforward dewatering and rehabilitation program to provide access for drilling."

The Phase I drilling program utilizing two underground rigs includes 36 planned core holes for a minimum 5,000 meters targeting gold and silver mineralization in the Marc, AV and JW zones. This drilling will target inferred resources, primarily within the JW zone with the objective of upgrading to measured and indicated categories. Step out holes are also planned along strike and down-dip from the current resource. Additionally, multiple metallurgical holes are planned throughout the mineralizing system for detailed metal recovery, geotechnical and hydrological studies.

"The geologic, engineering and environmental baseline information collected during the 2016 program will be used for IDM's planned feasibility study, to be completed in early 2017," said Michael McPhie, Executive Chairman. "Additionally, our exploration work will further demonstrate the significant upside at Red Mountain."

IDM has also initiated a comprehensive surface program of mapping and sampling, including targeting new areas of the 17,000 hectare property that have recently been exposed by rapid glacial melt. Assays from initial surface work on the Property are currently pending. The objective of this surface exploration work is to identify new drill targets within the widespread alteration and mineralizing system at Red Mountain.

Additionally, the Company is continuing with ongoing surface engineering work and environmental baseline studies in the project study area. This includes detailed surveys for the tailings management facility, mill, and ore stockpile at the proposed Bromley Humps location as well as the access road and proposed power line right-of-way, and planning for surface facilities. Ongoing hydrological and environmental studies are being performed in support of the environmental assessment process currently underway for the project by BC and Canada.

About Red Mountain

The 17,125 hectare Red Mountain Gold Project is located in northwestern BC, 15km northeast of the town of Stewart. Discovered in 1989, the property was explored extensively until 1996 by Lac Minerals Ltd. and Royal Oak Mines Inc., with 466 diamond drill holes and over 2,000 meters of underground development completed, along with extensive engineering and environmental baseline work. Additional studies were completed over the past 12 years by Seabridge Gold Inc., North American Metals Corp. and Banks Island Gold Ltd.

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 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.

QA/QC AND QUALIFIED PERSON

Samples for the 2016 program are collected by experienced geologists and technicians, placed in sealed bags and shipped to ALS Labs Ltd in Terrace, BC for sample preparation, with pulps subsequently shipped to Vancouver, BC for gold and multi-element ICP analysis. A Quality Control/Quality Assurance program including the insertion of Standards and Blanks has been implemented. The 2016 Exploration Program is performed under the supervision of Rob McLeod, P.Geo, President and CEO of IDM Mining Ltd and a 'Qualified Person' under NI 43-10. Mr. McLeod has reviewed and approved the technical content of this release.
