Dominion Diamond Announces Jay Project Water Licence Recommended for Approval

YELLOWKNIFE, Northwest Territories — Dominion Diamond (the “Company” or “Dominion”) is pleased to report that the Wek’èezhìi Land and Water Board (“WLWB”) has amended the Type A Water Licence for the Ekati Diamond Mine to include the Jay project. The WLWB has recommended that the amended Water Licence be approved by the Minister of Environment and Natural Resources, Government of the Northwest Territories, the Honourable Robert C. McLeod.

“We appreciate the work of the WLWB in continuing to advance the Jay project through the permitting process, and we look forward to final Ministerial approval and receipt of the Water Licence,” said Jim Gowans, Chairman of the Board of Directors of Dominion. “The Jay project is a platform for future growth at Ekati, extending the mine life to 2033, and is part of our overall growth pipeline that will deliver benefits to our many stakeholders.”

The Jay project is located in the Buffer Zone Joint Venture in which the Company has a controlling interest. Jay was approved for construction by the Company in July 2016 and is a significant undeveloped deposit given its large size and high grade.
