Detour Gold receives federal approval for Detour Lake Mine, in Ontario

TORONTO, ONTARIO–(Marketwire – Dec. 22, 2011) – Detour Gold Corporation (TSX:DGC) (“Detour Gold”) is pleased to announce the approval of the Comprehensive Study Report (“CSR”) regarding the environmental assessment for the Detour Lake project by the Federal Minister of Environment.

The Minister has determined that the project is not likely to cause significant adverse environmental effects with the implementation of the mitigation measures outlined in the CSR and has therefore referred the project back to the responsible authorities, Fisheries and Oceans Canada and Natural Resources Canada, for the issuance of permits.

During the Environmental Assessment (“EA”) process, local communities and Aboriginal groups provided both traditional ecological knowledge and third party review of the proposed Detour Lake mine. The input received improved the project design and will positively influence the mining operations, which are currently planned for a period of at least 20 years. The mine will provide sustainable, long-term employment for the local Aboriginal groups and communities in northern Ontario, with up to 1,200 workers required during construction and 500 employees during production.

Gerald Panneton, President and CEO of Detour Gold said, “We would like to thank Minister Peter Kent, the Canadian Environmental Assessment Agency and the federal review team for their excellent work throughout the CSR process. The Detour Lake mine is expected to generate over $14 billion of GDP benefit and create significant new employment in the Cochrane region. We are committed to working with all levels of government and communities to maintain the highest standards in environmental stewardship.”

Derek Teevan, VP Government and Aboriginal Affairs of Detour Gold added, “The CSR process was very thorough and is the result of collaborative and extensive consultations with government agencies, Aboriginal groups and Detour Gold’s consultants, AMEC, to ensure we have a solid design and operating procedures that meet all regulatory requirements.”
