VANCOUVER, June 29 /PRNewswire-FirstCall/ -- Northgate Minerals Corporation (TSX: NGX, NYSE Amex: NXG) is pleased to announce that a three-year Employee Collective Agreement (the "Agreement") has been ratified by the Employee Collective, comprising of 190 production and maintenance employees for the underground and surface operations at the Fosterville Gold mine located in Victoria, Australia. This Agreement replaces the Australian Workforce Agreements and a temporary Greenfield agreement that was put into place in April 2008 when Northgate completed its conversion to owner mining from contractor mining. Ken Stowe, President and CEO stated, "Shortly after acquiring the Fosterville Gold mine, we quickly transitioned to owner mining with the focus on turning around the operation. We hired virtually the entire workforce from the former contractor and our new workforce embraced the opportunity to participate in this successful turnaround. A year later, we are extremely pleased to have reached a three-year Collective Agreement with our employees at Fosterville and I would like to commend the significant contributions from the two negotiating teams during this extensive process. Equipped with a strong resource base, we will continue with our goal of growing both production and reserves, and are backed by a dedicated workforce who is committed to the long-term success of the mine." -------------- Northgate Minerals Corporation is a gold and copper producer with mining operations, development projects and exploration properties in Canada and Australia. The company is forecasting record gold production of over 390,000 ounces in 2009 and is targeting growth through further acquisition opportunities in stable mining jurisdictions around the world. Northgate is listed on the TSX under the symbol NGX and on the NYSE Amex under the symbol NXG. -------------- Forward-Looking Statements: This Northgate press release contains "forward-looking information", as such term is defined in applicable Canadian securities legislation, concerning Northgate's future financial or operating performance and other statements that express management's expectations or estimates of future developments, circumstances or results.
