Dominion will operate as a standalone, private company. Patrick Evans has been appointed Chief Executive Officer, effective immediately.

Patrick Evans, CEO of Dominion, said, “I am pleased to join Dominion Diamond at this exciting time for the Company. I will work relentlessly with management and our talented employees to help realize the long-term potential of Dominion’s world-class assets, specifically by extending the life of the Ekati mine, investing to develop the Jay Project and reinvigorating our exploration program. I have long admired Dominion Diamond’s deep ties to the Northwest Territories and Nunavut and to Yellowknife in particular, and I look forward to continuing that legacy with the full support and resources of The Washington Companies.”

“This is an exciting day for Dominion Diamond and The Washington Companies,” said Lawrence R. Simkins, President of Washington. “We fully support Dominion’s existing strategy and its exceptional employees, and we are confident that Dominion will continue to offer long-term benefits to all of the Company’s stakeholders.”

“The Washington Companies and Dominion Diamond have proven track records as responsible, innovative operators,” said Dennis Washington, Founder of The Washington Companies. “With today’s closing, I am excited to join forces with Dominion as well as with our respected partner at the Diavik mine – Rio Tinto. We look forward to owning and operating Dominion for decades to come, with a focus on maintaining safe and prosperous business operations in the Northwest Territories.”
