     VANCOUVER, Feb. 18 /CNW/ - Northgate Minerals Corporation (TSX: NGX,

     Ken Stowe, President and CEO, commented, "After a lengthy process, we are
extremely pleased to announce the completion of this transaction, which marks
an important milestone for Northgate. Our targeted objective has been
significant production growth in stable jurisdictions and the Perseverance
transaction is exactly that. We are now an unhedged, multi-mine gold producer
with three fully permitted operations in Canada and Australia, with combined
production of over 400,000 ounces of gold expected in 2008. We are in an
excellent position to further our growth through the development and
exploration at our existing operations and projects while continuing to
evaluate additional acquisition opportunities."

operations in its consolidated financial results for the period ending
March�31, 2008. The company also plans to update its previously released 2008
production guidance to include the Fosterville and Stawell mines acquired in
the transaction.

through further acquisition opportunities in stable mining jurisdictions
around the world. Northgate is listed on the Toronto Stock Exchange under the
