Canadian Zinc Corp. reported that on January 18, 2013 the company filed its' written responses to the interventions previously submitted to the Mackenzie Valley Land and Water Board by various government departments and other parties on January 11, 2013 in reference to the company's application for a Water Licence for the operation of the Prairie Creek Mine in the Northwest Territories. The permitting process is being conducted by the Mackenzie Valley Land and Water Board and the Response submission is the last document to be filed prior to the upcoming Public Hearing scheduled for the end of January.

Written Interventions were filed on January 11, 2013 by Aboriginal Affairs and Northern Development Canada, Parks Canada, Naha Dehe Dene Band, Canadian Parks and Wilderness Society, and a Joint Intervention by Fisheries and Oceans Canada and Environment Canada. Most of the Interventions relate to water management and include many recommendations made by the various government departments. The main purpose of a Water Licence is to regulate the discharge of water to the environment via the application of licence terms and conditions and the establishment of effluent quality criteria.

In its responses, filed January 18, 2013, Canadian Zinc reiterated its proposals and recommendations with regard to regulating the discharge of water into the environment. The Water Board has issued a Notice of Public Hearings to be held in Fort Simpson on January 29-31, 2013 and in Nahanni Butte on February 1, 2013. The Hearings, conducted by the Water Board, are prescribed under the Mackenzie Valley Resource Management Act, and provide an opportunity for local communities and members of the public to participate and have a say in the permitting process.
