VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Oct. 11, 2005) - Northgate Minerals Corporation (TSX:NGX)(AMEX:NXG) is pleased to report that it has submitted the Environmental Impact Assessment Report (EIA) for the development of the Kemess North mine to the Joint Federal/Provincial Environmental Review Panel. The EIA Report consists of an EIA Summary document and 14 supporting appendices which present environmental, socio-economic, geological and engineering data and interpretation relating to all aspects of the Kemess North development.

Ken Stowe, President and CEO of Northgate, commented; "The submission of the Kemess North EIA represents the culmination of three years of concerted effort by our project team to generate a comprehensive document that presents an environmentally sound case for the development of Kemess North. With this milestone behind us and the review process on schedule, we still expect to see the Panel's final report by the middle of next year at which time we will be in a position to make our final development decision."

Within the next few days, the Review Panel will officially release the Kemess North EIA Report for a 60-day public comment period designed to ensure that the report meets all the terms of the EIA guidelines issued by the panel in August.

About Kemess North:

Kemess North is an undeveloped gold/copper deposit containing 4.1 million ounces of gold and 1.5 billion pounds of copper, located approximately six kilometers north of the Kemess South mine. Development of the Kemess North open pit and the expansion of Northgate's existing Kemess milling infrastructure is forecast to cost US$190 million and will extend the productive life of the Kemess operation and sustain the jobs of some 450 employees and contractors until at least 2019. Annual metal production during the mine's 13 year life will average 250,000 ounces of gold and 113 million pounds of copper.
