Recognizing that further time will be required for his continuing recovery, and the limitations imposed during this period, Bob has decided to step down from the role of CEO and will now be Non-Executive Chairman. The Board is delighted that Bob's experience and expertise in the diamond mining industry, and his relationships within the mining industry, will continue to be available to the company in this capacity. Bob has also agreed to be a consultant in specific areas, such as the Jay project.

Since joining the Company, Brendan Bell has taken on increasing responsibilities and has been Acting CEO since November 2014. Brendan has demonstrated strong leadership during this period and his experience has prepared him well to take on this appointment.

Daniel Jarvis, who will be continuing as Lead Director, notes, "Bob's return and Brendan's appointment provides Dominion with very strong leadership at a time when the Company is well positioned for growth."
