Northgate revises fourth quarter metal production forecast

    VANCOUVER, Nov. 29 /CNW/ - Northgate Minerals Corporation (TSX: NGX,
AMEX:   NXG) today announced an update of its fourth quarter 2007 metal
production at Kemess South, reflecting ore scheduling changes necessitated by
the realignment of a portion of the ramp system in the west-end of the Kemess
pit. This realignment was initiated to remediate localized cracking and
deterioration in a 150-metre section of the ramp. As a result of the
realignment work, there will be a delay in accessing high-grade gold ore that
was originally scheduled to be milled in December. Mill feed for December will
now be sourced from the high copper, low gold supergene ore stockpile.
Subsequently, mill feed for January will come from hypogene ore stockpiles and
hypogene ore production in the eastern end of the open pit.
    As a result of rescheduling ore feed to the mill, fourth quarter 2007
gold production is now forecast to be 45,000 ounces instead of the previously
released figure of 65,000 ounces and copper production is forecast to increase
to 21 million pounds compared to the previous guidance of 17 million pounds.
Revenues for the quarter will not be materially different than they would have
been under the original production plan, but Kemess' net cash cost of gold
production during the fourth quarter will be substantially lower than
originally forecast due to the additional copper production and lower gold
production. The net cash cost for the quarter is now projected to be negative
$215 per ounce assuming an average copper price of $3.20 per pound and a
Canadian/US dollar exchange rate of $1.02.
    Realignment of the ramp is expected to be completed in January and
milling of the higher-grade gold ore originally scheduled for December 2007 is
now scheduled to occur in March 2008.
    Northgate plans to release final Kemess South metal production figures
for 2007 and metal production and cash cost guidance for 2008 in mid-January
