Building a world class independent exploration, development and production company takes vision, dedication and passion, and I have attempted to bring these to my time as CEO of Premier.

We can be proud of what we as a team have achieved but, after 9 years, I believe now is an appropriate time for a change in leadership as the business moves into its next phase. I am also looking forward to pursuing new business opportunities but in the meantime will continue to devote all my energies to ensuring the continued success of Premier."Mike Welton, Chairman, commented:

"I would like to thank Simon on behalf of the Board, shareholders and staff for his enormous commitment and contribution to Premier over the past 9 years. The Board wishes Simon well as he moves on to new ventures and thanks him for acting to ensure a smooth transition for the business until his successor is appointed."
