IDM Mining's Red Mountain Gold Project Environmental Assessment Referred to Provincial Ministers for Decision

VANCOUVER, Aug. 29, 2018 /PRNewswire/ - IDM Mining Ltd. (TSX.V:IDM) (OTCQB:IDMMF) ("IDM" or the "Company") is pleased to announce that the British Columbia Environmental Assessment Office ("EAO") has completed the Application Review phase for the proposed Red Mountain Gold Project ("Red Mountain" or the "Project").

The EAO has referred the Company's Application for an Environmental Assessment Certificate ("EAC") to the Minister of Environment and Climate Change Strategy and the Minister of Energy, Mines and Petroleum Resources for a decision. In accordance with the Environmental Assessment Act, Ministers have up to 45 days to decide whether to issue a certificate, not issue a certificate, or require further assessment. Referral materials and the Ministers' decision will be posted on the EAO website within the next 45 days.

In 2017, IDM submitted the Application for an underground gold mine at Red Mountain, mill and tailings site in the adjacent Bitter Creek Valley, water treatment facilities, access road from Highway 37 just north of Stewart, BC and powerline interconnection from BC Hydro grid. The Application Review phase included environmental and socioeconomic reviews with dozens of technical working group members and stakeholders, with respectful and thorough consultation with the Nisga'a Nation.

"We are very pleased that we have been able to resolve all key issues relating to the environmental assessment of the Red Mountain Project" said Michael McPhie, Chair of IDM's Board of Directors.  "We are confident that a positive decision from the Ministers will be made in the near-term and look forward to moving ahead with the development of the Project."

"Our vision for BC's next high-grade bulk underground gold mine is another step closer. We believe that the proposed low-footprint Red Mountain operation will have obvious benefits to my hometown of Stewart, to Nisga'a citizens and to residents throughout northwestern BC," said Robert McLeod, President and CEO of IDM Mining. "We look forward to continuing to increase resources and making new discoveries at Red Mountain, as well as completing the updated feasibility study incorporating value engineering improvements from the 2017 study and the increased measured and indicated resources from the June 2018 resource estimate."

Provincial Environmental Assessment Certificate

The Project commenced the 180-day legislated application review period under the British Columbia Environmental Assessment Act on November 1, 2017.  IDM received and responded to review comments from the technical working group co-led by the EAO and the Canadian Environmental Assessment Agency ("CEA Agency"), which included the participation of Nisga'a Nation (as represented by Nisga'a Lisims Government) and regulatory agencies.  IDM also responded to feedback from community members and stakeholders during the public consultation period (Nov 14 to Dec 14, 2017).

On March 12, 2018, IDM requested a temporary suspension of the application review period and it was granted by the EAO the following day to allow for final resolution of several outstanding technical comments and information requests.

The temporary suspension was lifted on July 13, 2018 and at that time the Project was on day 137.  The application review period finished on August 28, 2018 and the Application has been referred to the Minister of Environment & Climate Change Strategy and the Minister of Energy, Mines & Petroleum Resources for an EAC decision. The Minister's have 45 days to complete their review and render a decision on the Project.

Canadian Environmental Assessment Act Review

The Project is also subject to a coordinated review by the CEA Agency under the Canadian Environmental Assessment Act, 2012 (CEAA 2012).  On December 22, 2017, IDM received supplementary information requests on the EIS, pausing the federal timeline on day 122 of the federal legislated timeline of up to 365 days.  On May 17, 2018 IDM was informed by the CEA Agency that all supplementary information requests had been satisfied and the federal environmental assessment review process was resumed.  The federal review timeline is currently at day 225 of 365.   

With the provincial environmental assessment now nearing completion and the federal environmental assessment now advancing forward in a straightforward and predictable manner, IDM anticipates receiving federal approval in late 2018 or early 2019.
