This profile is part of a paid investor education campaign.*


IDM Mining (TSXV:IDM, OTCQB:IDMMF) is a Canadian advanced exploration and development company based in Vancouver, British Columbia. Their 17,125-hectare Red Mountain Gold Project is located 15 kilometers east of the mining town of Stewart, British Columbia, within the Nisga’a Nation’s treaty territory. The project also falls within British Columbia’s prolific Golden Triangle, an area that has faced a recent resurgence in exploration due to significant new discoveries, new mines, increased infrastructure and receding glaciers revealing new mineral occurrences. Since 2015, two projects within the Golden Triangle have gone into commercial production, Imperial Metals’ Red Chris copper/gold mine and Pretivm’s Brucejack high-grade gold mine. IDM Mining is set to become one of the Golden Triangle’s next high-grade, low-cost gold producer.

In 2014, IDM acquired the Red Mountain project from Seabridge Gold (TSX:SEA). Since then, the Company has been conducting extensive exploration work on the property. The project hosts a 2018 NI 43-101 measured and indicated resource of 704,600 ounces of gold averaging 7.91 g/t gold and 2,026,800 ounces of silver averaging 22.75 g/t silver. This is complemented by an inferred resource of 61,400 ounces of gold averaging 6.04 g/t gold and 77,200 ounces of silver averaging 7.60 g/t silver.

In 2017, IDM released a feasibility study for the Red Mountain project which confirmed the positive economics for a near-term, low Capex, high-grade, bulk mineable underground gold operation.  IDM intends to update the 2017 feasibility study incorporating the 2018 updated resource estimate into the mine plan, as well as engineering optimization work. The project was granted its environmental assessment (EA) certificate by the British Columbia Minister of Environment and Climate Change Strategy and the Minister of Energy, Mines and Petroleum Resources on October 5, 2018.

“This is a significant step for the Company and the realization of the potential of the Red Mountain gold project. With the successful completion of a rigorous process in a timely way, we have demonstrated the value and validity of our approach to project permitting, community engagement and project development” said IDM Chairman Michael McPhie.

Working within the Nisga’a Nation, IDM has been closely engaging with their government with the objective of a definitive Benefits Agreement. Since 2017, the Company and its contractors have provided over 1,600 person days and on-the-job training for Nisga’a citizens. They are being trained in all areas of mining—both in the field, including: miners, drillers and diesel mechanics, and in the Company’s head office in Vancouver.

IDM’s management team has experience in discovery, exploration, development, operations and M&A. McLeod, for instance, is a third-generation miner who grew up in Stewart and worked on Red Mountain when he first started his career. Management team members Michael McPhie, Susan Neale and Ryan Weymark collectively bring a vast amount of experience in permit applications, small and large-scale project development and a commitment to ensuring that the project is successful. The Red Mountain mine manager, Dave Green, is also a provincially respected and experienced development miner, and he contributes to the project’s success by running an efficient and effective operation.

Red Mountain Gold Project

In 2014, IDM signed an LOI with Seabridge Gold to acquire a 100% interest in the high-grade Red Mountain Gold Project. It is located approximately 15 kilometers east of the town of Stewart, British Columbia and is within the Nisga’a traditional territory. The project comprises a total of 17,125 hectares and is situated in British Columbia’s Golden Triangle.

The deposits at Red Mountain sit in Triassic and Jurassic age sedimentary and volcanic units. There are two porphyries on the property that can be differentiated by mineralogy, texture and geochemistry, which show the fractionation and depletion of a shared magmatic source over time.

Historical Work

Between 1989 and 1996, Lac Minerals Ltd. and Royal Oak Mines Ltd. explored the Red Mountain property extensively. There were 466 drill holes completed and over 2,000 meters of underground development completed. There has also been extensive environmental and engineering baseline work completed during this time. An additional 12 years of studies have been completed by Seabridge Gold, North American Metals Corp. and Banks Island Gold Ltd.


Before IDM acquired the property, there had been no significant exploration work conducted since 1996. Since acquiring the property IDM has conducted a number of exploration and drilling activities that have uncovered multiple mineralization zones including the AV, JW, Marc and JW/SF zones.

In 2017, IDM continued its drilling activities, with the goal of increasing the property’s resources and the conversion of inferred resources to measured and indicated. 2017 drilling highlights included:

  • 7 meters of 14.62 g/t gold and 79.26 g/t silver and 25 meters of 13.67 g/t gold and 30.91 g/t silver at the AV zone;
  • 8.6 meters of 12.33 g/t gold and 70.90 g/t silver at the JW zone;
  • 4.88 meters of 149.24 g/t gold and 59.88 g/t silver and 26.61 g/t gold and 88.19 g/t silver at the Marc zone; and,
  • 3.78 meters of 38.27 g/t gold and 59.39 g/t silver at the JW/SF zone.

Some 2016 drilling highlights include:

  • 15.54 meters of 25.50 g/t gold and 50.92 g/t silver and 35.60 meters of 8.43 g/t gold and 35.60 meters of 8.43 g/t gold and 12.82 g/t silver at the AV Zone;
  • 15.00 meters of 19.39 g/t gold and 48.14 g/t silver and 10.43 meters of 21.53 g/t gold and 12.27 g/t silver at the Marc Zone; and,
  • 19.80 meters of 8.46 g/t gold and 25.53 g/t silver at the JW Zone.

The Company recently had a significant breakthrough in the geological interpretation of Red Mountain, which will help guide future exploration and was incorporated into the 2018 resource estimate.

2018 fieldwork, including mapping and trenching, has commenced within the Lost Valley area of Red Mountain, located 4km to the south of the resource area. This program is designed to identify new targets, expand upon known zones and refine surface drilling targets.

Rapidly melting glaciers have revealed new discoveries and prospective geology on the property. Red Mountain and Lost Valley are part of a 16km long trend of prospective geology, including historic mines that have never been explored by IDM. The Company plans ongoing regional exploration, in parallel to advancing the project towards production by 2021.

Exploration at Lost Valley

Lost Valley was discovered in 2016 when the Cambria icefield had receded enough to reveal the underlying bedrock. Multiple phases of quartz veining have been identified, containing coarse-grained pyrite, which is commonly found with molybdenite, chalcopyrite and sphalerite mineralization.

Results from 2016 assay up to 165 g/t gold and 1,048 g/t silver. Multiple generations of vein sets occur, with earlier stockworks up to wide shear zones and individual veins.

“Melting alpine glaciers have revealed significant new discoveries in the Golden Triangle area of British Columbia during recent years, including Pretium’s Valley of the Kings gold-silver deposit and Seabridge’s Mitchell gold-molybdenum deposit,” said McLeod. “The new, high-grade gold, silver and molybdenum-bearing structures found over an extensive area at Red Mountain suggest that the Lost Valley area could be the latest discovery in this prolific region of the province. This area was under a glacier when I worked on the Property as a junior geologist in the 1990’s and is now emerging as an exciting new zone of potential significance.”

Resource Estimate and Reserve

On June 19, 2018 IDM published an updated resource estimate. The property hosts a measured and indicated resource of 2.7 million tonnes containing 704,600 ounces at 7.91 g/t gold and 2,026,800 ounces at 22.75 g/t silver. This is supported by an inferred resource of 316,000 tonnes containing 61,400 ounces at 6.04 g/t gold and 77,200 ounces of 7.60 g/t silver.   Resources are reported at a 3.0 g/t Au cut-off grade.

Feasibility Study

In 2017, IDM released a feasibility study for the Red Mountain project which confirmed the positive economics for a near-term, low Capex, high-grade, bulk mineable underground gold operation.

IDM intends to update its 2017 feasibility study by the end of 2018, incorporating the 2018 resource update estimate into the mine plan as well as theongoing value engineering studies that outlined several opportunities to reduce costs and improve the value of the project.

Opportunities include:

  • Reducing the long-hole and cut-and-fill transition, reducing the percentage of higher-cost cut-and-fill mining;
  • Investigating the Holloway method as an alternative to cut-and-fill to further reduce operating and sustaining capital costs;
  • Optimizing the infrastructure design and layout to reduce quantities of earthworks, concrete, steel, electrical and piping;
  • Optimizing the crushing and grinding circuits to maximize the use of high-efficiency mills; and
  • Increasing throughput from 1,000 tpd to increase annual gold production above 100,000 oz annually.

Moving Forward

IDM has recently received its EA certificate from the BC provincial government. The certificate presents 38 conditions as well as legally binding design requirements that IDM must comply with. The conditions were developed after consultation with Indigenous groups, government agencies, communities and the public.

The project is now also subject to a review by the Canadian Environmental Assessment (CEA) agency under the CEA Act of 2012 (CEAA 2012). The project is currently advancing towards the final stage of assessment, and IDM expects receipt of federal approval by late 2018 or early 2019.

Currently, IDM is working on scoping the Mines Act (MA) and Environmental Management Act (EMA) permits, which will be submitted after receipt of the EAC and EIS. The company is expecting to receive the MA and EMA permits in 2020, authorizing construction of the mine which is expected to be operational by the end of 2021.

IDM will also continue its exploration efforts focused on expanding the project’s resources.
