IDM Mining Announces Initial 2018 Sampling Results from Lost Valley Target, Red Mountain Project

VANCOUVER, July 11, 2018 /PRNewswire/ - IDM Mining Ltd. (TSX-V:IDM) (OTCQB: IDMMF)("IDM" or the "Company") is pleased to announce initial surface sampling results from trenching at the Money Rock zone at the Lost Valley target, within the 100%-owned Red Mountain Gold Project ("Red Mountain" or the "Project"), located in the Golden Triangle of northwestern British Columbia, near the town of Stewart, BC.

"These new high-grade samples and exposures at Money Rock, located 4,000 meters south of the resources at Red Mountain, further emphasizes the regional exploration potential at Red Mountain," said Robert McLeod, President and CEO of IDM Mining.  "Mapping, trenching and sampling is increasing our understanding of the mineralized structures at Lost Valley, with additional assays expected over the coming weeks."

2018 Lost Valley Sampling

Assay results have been received from 58 samples to-date during 2018 and consist primarily of panel, channel and grab samples with local float samples. The total of all samples averaged 11.62 g/t Au and 47.39 g/t Ag. Samples range from trace to 69 g/t Au and trace to 164 g/t Ag.  A total of 24 samples assayed over 5.0 g/t Au. Sample distribution maps are available on the Company's website and within the Red Mountain virtual tour on the Vrify site.

Most of these samples are from the Money Rock structure, which has been exposed by trenching for over 100 meters of strike length.  Systematic samples have been collected both along strike and across its thickness for the best sample representation. Continuous, one-meter-long panel samples along the length of 32 meters of strike of newly exposed mineralization in the Money Rock structure averaged 13.17 g/t Au and 54.29 g/t Ag. Samples range from 0.07 to 69.0 g/t Au and 0.49 to 145.00 g/t Ag.  The panel samples were collected on strike of the structure with the objective of being representative of the entire length and width of the interval. Width of the structure, including veining and faulting, varies from approximately 0.8 to 2.5 meters, averaging about 1.5 to 2.0 meters.  Numerous additional assays are pending, collected further along and across strike.

During 2016, three drill holes from a single drill pad were completed at the Money Rock zone, where across strike channel sampling averaged 18.7 g/t Au and 61.4 g/t Ag over 0.84 meters along a 33-meters of strike.  These samples locally overlap the 2018 sampling. Drill hole LV16-01 intersected 1.0 meters of 3.0 g/t Au and 23.80 g/t Ag, and LV16-02 intersected 1.2 meters averaging 4.63 g/t Au and 90.90 g/t Ag. All three holes intersected a post-mineralization dyke where the zone was projected to occur from surface trenching (see IDM NR November 17, 2016).  Future drilling will target areas to the west and east of this dyke.

Lost Valley Target

Recently exposed by melting glaciers, the Lost Valley discovery is located approximately 4,000 meters southwest, of resources at Red Mountain (see IDM NR June 19, 2018) within the headwaters to the Bitter Creek Valley.

Mineralization at Lost Valley is hosted within a gold and molybdenum bearing granitic intrusion with multiple generations of quartz-sulphide veining.  Recent trenching has exposed over 100 meters of strike length of the Money Rock zone, with variable widths of veining and faulting, ranging from one to 2.5 meters in thickness.  This structure is associated with ductile deformation, sericite and clay alteration as well as brittle faulting.  Within the zone, banded quartz veins and massive sulphide pods host primarily pyrite, with lesser molybdenite, bismuthinite and other base-metal sulphides.  The structure is comprised of duplexing brittle-structures, occurring along the base of a cliff. 

The Money Rock structure potentially connects with the Randell Vein. A hand trench sampled in 2016 within sub-cropping of quartz and sulphide averaged 22.4 g/t Au and 81.7 g/t Ag over a continuous 9.25 meter-long channel. Two holes, both vertical, were drilled form surface in 2016 but did not intersect any faulting or veining, suggesting that the target structure was not drilled with correct orientation.  The Randell vein is currently being trenched.

About IDM and Red Mountain

IDM Mining Ltd. is an exploration and development company based in Vancouver, BC, Canada focused on advancing the Red Mountain Gold Project towards production.  The 17,125 hectare Red Mountain Gold Project is located in northwestern BC, 15 km northeast of the mining town of Stewart.  IDM recently announced increased high-grade, near surface measured and indicated resources. 

The updated mineral resources for the Red Mountain Project are reported at a 3.0 g/t Au
cut-off with an effective date of June 15, 2018.

The Project is advancing through the provincial and federal environmental assessment processes, with comprehensive, thorough, and ongoing consultation with Nisga'a Nation.  The Project is currently in the formal review phase of the BC Environmental Assessment Office and the Canadian Environmental Assessment Agency. 

QA/QC and Qualified Person

Samples for the 2018 program are collected 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.  The 2018 Exploration Program is performed under the supervision of Robert 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.
