management changes and the impending move of the Company's
headquarters from Denver to Toronto. 
The Board announced the following management changes:

    Mair, CEO, has elected to remain in Denver and will resign his
    position and Board seat effective December 31, 2012.

Golden Star's new Toronto headquarters will be located at 150 King
Street West, Toronto, Canada.  
Chris Thompson, Chairman of the Board, said, "Relocating our
headquarters to Toronto enables us to consolidate our executive team
along with all key accounting and reporting functions in one location
that will give Golden Star better access to shareholders, capital
sources, talent and technical advisory services. The move will also
simplify the Company's accounting and regulatory compliance functions
and reduce legal costs. On behalf of the Board, I wish to thank Tom
Mair for his six years of leadership through some difficult times and
we wish him success in his further endeavors in Denver. Going
forward, we believe we now have a uniquely strong team in place --
both in Toronto and Ghana -- to take Golden Star to the next level of
growth. In particular, we look forward to the relationship between
Sam Coetzer and Tim Baker flourishing as it did when they worked
together at Kinross Gold. Their combined track records of success in
operations and demonstrated leadership capabilities give the Board
every confidence that the challenges and opportunities we face on the
Prestea Underground mine and Wassa expansion are in good hands."
