Acadian Mining Corporation (TSX: ADA) ("Acadian" or the "Company") is pleased to announce that at its annual and special meeting of shareholders on June 9, 2009 ("Meeting") the Acadian shareholders voted in favour of a resolution to approve the second tranche of private placement with Golden River Resources Corporation ("Golden River").  Acadian is also pleased to announce the appointment of Menachem Vorchheimer to its board of directors. 

Pursuant to a letter agreement dated March 16, 2009, Acadian agreed to a private placement with Golden River involving the issuance of up to 338,111,334 common shares for aggregate gross proceeds of up to $10 million.  The private placement was comprised of two tranches.  The first tranche, comprised of 38,111,334 common shares for aggregate proceeds of $1 million, closed in two closings � one on April 3, 2009 and the other on June 1, 2009. 

The second tranche of the private placement ("Second Tranche"), 300,000,000 shares at $0.03 per share for aggregate proceeds of $9 million, was subject to the approval of shareholders and to the satisfaction of certain other conditions.  See news release 06-05 dated April 3, 2009 for further details.

The proceeds of the Second Tranche are to be used by Acadian for operational overheads, the advancement of Acadian�s gold properties and the discharge of creditors of Acadian and its wholly-owned subsidiary, ScoZinc Ltd., all in accordance with a plan and budget approved by Golden River.

At the Meeting, shareholders re-elected all Acadian's existing directors, namely Jasche Boge, Jim Borland, Terry Coughlan, Herman Felderhof, Will Felderhof and Glenn Williams.  In accordance with the terms of the agreement with Golden River, Golden River was entitled to appoint a nominee to the board of Acadian once the first tranche of the private placement was completed.  Following the Meeting, Menachem Vorchheimer was added as an additional member of the board as Golden River�s nominee. 

"I am very pleased that the shareholders of Acadian have endorsed the private placement with Golden River.  I believe it will give Acadian the opportunity to restructure and move forward.  The Golden River group has a strong and very successful track record for developing and operating gold mines in Australia and I believe that they will be instrumental in helping Acadian grow into a sizeable North American mining company that will bring value to all shareholders", said Will Felderhof, President and Chief Executive Officer of Acadian.
