Vancouver, British Columbia, January 13, 2017 - Canadian Zinc Corporation (TSX: CZN; OTCQB: CZICF) (“the Company” or “Canadian Zinc”) is pleased to announce that, as part of its ongoing feasibility studies, the Company has engaged SGS Canada Inc. to undertake further mineral processing optimization testing on new composite bulk samples from underground drill holes in the Prairie Creek Mine in the Northwest Territories.
The principal objectives of the program are to examine new and unoxidized zones of the deposit, to optimize the proposed mineral processing flow sheet and to simplify the flotation circuit design, thereby improving the projected metal recoveries and lowering milling production costs.
The programs include definition of the grinding requirements and evaluation of the response of variability samples to the optimized processing method. In addition, the waste products generated in the test programs will be utilized in designing treatment plans for the process water and in testing paste tailings for underground disposal.
It is estimated the metallurgical program will take four months to complete and will provide valuable additional information on:
