All underground mining activities at the site had previously been carried out by MG Mining, a privately-owned Australian mining contractor. Under the agreement, all mining activities at the site have immediately been placed under the direct supervision of Northgate's management team at Fosterville and the company expects the transition of mining personnel and equipment from MG Mining to Northgate to be completed by June 30, 2008. Northgate is also pleased to announce the appointment of Mr. Luc Guimond to the position of Executive General Manager of its Australian operations effective March 10, 2008. In this role, Mr. Guimond will oversee the integration and management of Northgate's two new underground gold mines in Victoria, Australia. Mr. Guimond brings over 20 years of underground mine management and engineering experience to Northgate's Australia team. To assist in the integration of its recently acquired Australian mines, Northgate's Chief Operating Officer, Mr. Peter MacPhail, has relocated to Victoria to take on the position of Managing Director of Northgate Australia Ventures Corporation, a wholly-owned subsidiary of Northgate. Mr. MacPhail and Mr. Guimond will work closely with the existing operating teams at the Fosterville and Stawell mines on various strategic initiatives including an aggressive exploration program at Stawell, the gold recovery enhancement project at Fosterville and the aforementioned conversion to Owner Mining.
