IDM Mining Sampling of Historic Drill Core Yields 139 Meters of 1.59 g/t Au, Including 18.0 Meters of 5.45 g/t Au at 141 Zone, Red Mountain Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 14, 2015) - IDM Mining Ltd. (TSX:IDM) ("IDM" or the "Company") is pleased to announce that it has received results from sampling of un-assayed historic drill core from the 141 Zone at the Red Mountain Gold Project ("Red Mountain" or the "Project"), located 15 kilometers northeast of Stewart, British Columbia. The 141 Zone is located 280 meters southwest of the Marc/AV/JW Zones, which are host to the current NI 43-101 compliant mineral resource estimate at Red Mountain (the "Resource Area"). A proposed production ramp outlined in IDM's Preliminary Economic Assessment is expected to pass through the 141 Zone area (see IDM News Release July 23, 2014).

"Located in a similar geologic setting to giant gold deposits in northwest BC including KSM, Snowfield and Premier, the 141 Zone at Red Mountain is emerging as a significant mineralized area, open for further expansion," said Rob McLeod, President and CEO of IDM Mining.

During September 2014, three diamond drill holes were completed at the 141 Zone, which is located outside of the Resource Area, with mineralized intervals including: 138 meters averaging 1.41 g/t Au, with a high-grade zone of 7.5 meters averaging 10.45 g/t Au (see IDM news release November 13, 2014). These results, coupled with wide-spaced historic drilling, have demonstrated gold mineralization within an area of extensive low-grade porphyry-gold style mineralization at the 141 Zone (typically >1.0 g/t Au), as well as higher grade cores (>5.0 g/t Au).

Since acquiring the Red Mountain Project, IDM has conducted a sampling program of select drill holes of un-assayed core from drilling completed by Lac Minerals in 1993 and 1994. The objective of the historic drill programs at the time was to target high-grade gold, resulting in many areas of strong alteration and sulphide mineralization remaining un-sampled. A total of 68 core samples were submitted, covering un-assayed intervals ranging from 1.0 to 18.2 meters, from five holes. Individual samples were typically 1.0 to 1.5 meters in length.

Complete assay results and revised intervals are as follows:

Due to the wide-spaced drilling and complex geology of the 141 Zone, true thickness and orientation of mineralization is not yet fully understood.

The mineralized trend of the 141 Zone is subparallel with the Resource Area including the Marc/AV/JW Zones, spanning a broad area at least 325 meters long by 350 meters wide and is open for expansion in all directions. Infill and step-out drilling is planned for 2015, with the objective of completing an initial NI 43-101 resource estimate for the 141 Zone.

"The 141 Zone is a priority exploration target at Red Mountain," said Michael McPhie, Executive Chairman of IDM Mining. "Due to its close proximity to the Marc/AV/JW Zones, additional high grade mineralization from the 141 Zone would be complimentary to the Project Description for an underground mine, outlined in our PEA and Project Description for Environmental Assessment."

Gold mineralization at the 141 Zone is hosted within a complex assemblage of strongly altered hornblende-feldspar porphyry dykes and sills, intruding tuffaceous volcanics and sediments. Stockworks, veins and disseminations of pyrite and pyrrhotite correlates with gold values, typically in areas of strong sericite alteration, potassium feldspar alteration and silicification.

ABOUT RED MOUNTAIN

IDM Mining is currently earning an option to acquire a 100% interest in the 17,125 hectare Red Mountain property, located 15 kilometers northeast of Stewart, BC. Numerous precious and base metal targets have been identified by IDM and previous operators over a 15 km by 4 km trend of strong alteration and mineralized prospects. Since discovery in 1989, in excess of $40 million has been spent on the Project including a production sized underground ramp.

IDM recently announced positive results from a NI 43-101 PEA and revised Resource Estimate completed by JDS Energy & Mining Ltd. for Red Mountain (see IDM news release dated July 23, 2014). A technical report prepared in compliance with the requirements of the Canadian Securities Administrators' NI 43-101 has been filed on SEDAR and the Company's website.

At a 3.0 g/t Au cutoff, Measured and Indicated Resources from the Marc and AV Zones at Red Mountain are 1,454,300 tonnes averaging 8.15 g/t Au and 29.57 g/t Ag totaling 380,900 oz Au and 1,382,800 oz Ag. Inferred Resources from the Marc, AV and JW Zones are 332,900 tonnes averaging 7.69 g/t Au and 12.72 g/t Ag totaling 82,300 oz Au and 136,200 oz Ag.

QA/QC

The 2014 exploration program at Red Mountain included a rigorous Quality Control/Quality Assurance program, overseen by Rob McLeod, P.Geo, President and CEO of IDM Mining, and a Qualified Person as defined by NI 43-101. Drill cores were logged and cut in half using a diamond saw, with one half placed in sealed bags and shipped to Acme Analytical Labs' ("Acme") sample preparation facility in Smithers, BC, with pulps subsequently shipped to Acme's assay lab in Vancouver, BC. A total of 10% of all samples submitted include randomly inserted blank material or quality control standards. An additional 10% of samples will be shipped to a third party analytical lab for verification.

Mr. McLeod prepared and approved the technical information contained within this release.
