YELLOWKNIFE, NT (January 27, 2015) - Dominion Diamond Corporation (TSX: DDC, NYSE: DDC) (the "Company" or "Dominion") is pleased to announce the results of a pre-feasibility study ("Jay PFS") on the Jay kimberlite pipe deposit located within the Buffer Zone Joint Venture property in Canada's Northwest Territories. Dominion compiled and prepared the Jay PFS with the assistance of its consultants Golder Associates Ltd. and Peter Ravenscroft, FAusIMM, of Burgundy Mining Advisors Ltd. The Ekati Diamond Mine consists of the Core Zone (in which the Company owns an 88.9% interest), which includes the current operating mine and other permitted kimberlite pipes, as well as the Buffer Zone (in which the Company owns a 65.3% interest), an adjacent area hosting kimberlite pipes having both development and exploration potential, including the Jay kimberlite pipe as well as the Lynx kimberlite pipe.
Jay is the most significant undeveloped deposit at the Ekati Diamond Mine due to its large size and high grade. Jay is located beneath Lac du Sauvage, a moderate sized lake north of Lac de Gras, and is approximately 1.2 km from the shoreline. The Jay pipe is approximately 7 km to the northeast of the Misery Pit and related infrastructure, and 30km to the southeast of the main Ekati mine infrastructure.
