PROVINCIAL ENVIRONMENTAL ASSESSMENT REVIEW OF IDM MINING'S RED MOUNTAIN GOLD PROJECT ADVANCES TO FINAL STAGE

The temporary voluntary suspension of the 180-day time limit for the application review of IDM Mining Ltd.'s Red Mountain gold project has been lifted by the British Columbia Environmental Assessment Office and the project is now entering the final stage of the environmental assessment review.

"We are very pleased that all material issues relating to the provincial environmental assessment of Red Mountain have now been resolved and we can move into the final stage of the provincial environmental assessment process," said Michael McPhie, chair of IDM's board of directors. "With only 43 days left on the legislated provincial review timeline and key issues now resolved, we can look forward with confidence in our permitting and ultimate development timeline. This resolution represents a key step in our work with provincial and federal review agencies, the Nisga'a Nation, and local community representatives in terms of recognizing both the economic opportunity and environmental and social sustainability of the Red Mountain project."

Background

Provincial environmental assessment certificate

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

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

On March 13, 2018, EAO granted the temporary suspension, effective on day 134 of the 180-day application review period. Effective July 13, 2018, the temporary suspension was lifted and as of the date of this release, the project is now on day 137. Following the conclusion of the application review period in the coming weeks, the EAO will finalize its assessment report and submit recommendations to the Minister of Environment & Climate Change Strategy and the Minister of Energy, Mines & Petroleum Resources. IDM anticipates receiving the environmental assessment certificate in Q3 2018.

Canadian Environmental Assessment Act review

The project is also subject to a co-ordinated review by the Canadian Environmental Assessment Agency under the Canadian Environmental Assessment Act, 2012 (CEAA 2012). On Dec. 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 CEAA review process was resumed. The project review timeline is currently at day 182 of 365.

With the provincial EA process now nearing completion and the CEAA process now advancing forward in a straightforward and predictable manner, IDM anticipates receiving federal approval in the fourth quarter of 2018.
