Attention Business Editors:

Review panel announces recommendation report for Northgate's Kemess North Project to be submitted in September 2007

     VANCOUVER, Aug. 1 /CNW/ - Northgate Minerals Corporation (TSX: NGX; AMEX:
NXG) confirmed today that the Joint Federal-Provincial Environmental Review
Panel for the Kemess North project has indicated "that it's final report will
likely be completed and submitted to Ministers in September 2007. As soon as
the report is available, the Panel Secretariat will notify all parties of its
availability."
     Ken Stowe, President and CEO, stated; "We are obviously very disappointed
that the recommendation report on the Kemess North project will be delayed yet
again. At the same time, given the lengthy review process and the extensive
amount of technical data, reports and public input, we understand the
challenge facing the Panel in preparing this report. The Panel has now
indicated that the report will not be submitted until September instead of
early August as originally planned."
