Northgate reports fourth quarter operating results and production forecast for 2008

    VANCOUVER, Jan. 28 /CNW/ - (All figures in US dollars except where noted)
- Northgate Minerals Corporation (TSX: NGX, AMEX:   NXG) today reported its
fourth quarter 2007 operating results and 2008 production forecast, as well as
2008 exploration plans for its Canadian properties.


    -   Quarterly gold production of 41,467 ounces bringing total 2007
        production to 245,631 ounces;

    -   Quarterly copper production of 16.8 million pounds bringing total
        2007 production to 68.1 million pounds; and,

    -   Quarterly gold net cash cost of $48 per ounce bringing annual net
        cash cost to negative $16 per ounce of gold for all of 2007.

    -   Shareholders, warrant holders and noteholders of Perseverance
        Corporation Ltd. ("Perseverance") approved Northgate's offer to
        acquire the Australian gold producer and the transaction is expected
        to close on February 18, 2008.

                     2008 PRODUCTION FORECAST HIGHLIGHTS

    -   The Kemess mine is forecast to produce 243,000 ounces of gold and
        64.4 million pounds of copper in 2008.

    -   The cash cost of production, net of by-product credits, is forecast
        to be $130 per ounce of gold assuming a copper price of $3.00 per
        pound and an exchange rate of Cdn$/US$1.00.

    -   Canadian exploration spending is forecast to be $22 million, most of
        which will be devoted to the Young-Davidson property near Matachewan,
        Ontario. The surface and underground diamond drilling programs at
        Young-Davidson will continue and Northgate expects to complete a
        feasibility study for the project by the end of the year.

    -   Gold production from the Fosterville and Stawell mines in Australia
        is expected to be in the range from 190,000 to 200,000 ounces during
        2008 and this production will be included in Northgate's consolidated
        results after the transaction closes on February 18. Northgate will
        provide further production and cost guidance for its newly acquired
        Australian mines in March 2008.

    Ken Stowe, President & CEO, commented, "While the revised fourth quarter
production at Kemess fell short of our expectations, our total 2007 production
of 245,631 ounces of gold at a net cash cost of negative $16 per ounce
generated excellent cash flow in 2007's strong metal price environment. With
the acquisition of two operating mines in Australia, Northgate's total metal
production in 2008 is forecast to be over 400,000 ounces of gold and
64.4 million pounds of copper, all of which is unhedged, and will be sold at
spot prices giving us maximum exposure in the current robust metal price
environment. With successful securityholder votes behind us on the
Perseverance transaction and the upcoming resource update we expect to
announce at Young-Davidson, Northgate has become a multi-mine, mid-tier, gold
producer with production platforms in two excellent mining jurisdictions from
which we can generate additional growth opportunities through exploration and


    Q4 2007 - Kemess South Mine Performance

    The Kemess mine posted production of 41,467 ounces of gold and
16.8 million pounds of copper in the fourth quarter of 2007. Metal production
was significantly lower than forecast due to lower than expected mill
throughput and a 15% copper grade deficit compared to blast hole estimates for
the stockpiled, very unusual, high native copper ore that was milled from
stockpile in November and December. Milling of this ore and other lower grade
stockpiled hypogene ores during November and December was necessitated by the
realignment of the main haul road out of the pit due to a crack, which
developed in a section of the road. This realignment was completed on January
10, 2008 at which time ore production from the west end of the pit resumed.
For the full year, Kemess milled approximately 17.8 million tonnes of ore
grading 0.627 grams per metric tonne (gr/mt) gold and 0.214% copper and posted
gold and copper production of 245,631 ounces and 68.1 million pounds,
    The cash cost of production at Kemess in the fourth quarter was $48 per
ounce bringing the average 2007 cash cost to negative $16 per ounce.
    Northgate's audited financial results for the year ended December 31,
2007 are scheduled for release on February 28, 2008 and the Corporation's
year-end conference call and webcast for investors and analysts will be held
at 10:00 am (Eastern Standard Time) on the following day.
    The following table provides a summary of operations for the fourth
quarter and the full year of 2007 and the comparable periods of 2006.

    Kemess South Mine

    In 2008, the mine plan calls for the removal of 18.2 million tonnes of
ore and 19.0 million tonnes of waste from the Kemess South open pit. The
majority of this material, approximately 30 million tonnes, will be mined from
the western end of the open pit and the balance will come from the eastern end
of the pit where pre-stripping of waste for the 2009-2010 ore production will
commence in the second half of this year.
    Mill feed will be supplied by ore sourced from the western end of the
open pit and stockpiles and mill throughput is forecast to average
approximately 50,000 tonnes per day (tpd) with the mill operating at 92%
availability. The majority of the ore milled during the year will be hypogene
ore with only a small quantity ((less than)6%) of supergene ore. Total metal
production for 2008 is anticipated to be approximately 243,000 ounces of gold
and 64.4 million pounds of copper.
    Production of gold-copper concentrate is forecast to total 148,000 dry
metric tonnes (dmt), which will be shipped to Xstrata Copper's Horne smelter
in Rouyn-Noranda, Quebec. Annual smelting and refining terms for 2008 are
expected to settle at around $45/dmt and 4.5cents/lb of copper with no price
participation, which represents a reduction in concentrate marketing costs of
approximately $3 million from 2007 levels.

    Gold Cash Cost

    Assuming by-product copper and silver prices of $3.00 per pound and
$12.00 per ounce, respectively, and an exchange rate of Cdn$/US$1.00, the
Kemess mine's 2008 net cash cost is projected to be $130 per ounce of gold
produced. In 2008, each $0.10 per pound change in the copper price and each
$0.03 change in the Cdn$/US$ exchange rate will affect the net cash cost of
production by approximately $25 per ounce.

    Quarterly Metal Production

    Gold and copper output will vary from quarter to quarter due to normal
variations in ore grades, ore types and metallurgical recoveries. All of
Northgate's gold and copper production from Kemess South during 2008 is
unhedged; as a result, the company will receive market prices for all metal
sales during the year.

    Australian Mines

    Northgate's acquisition of Perseverance is scheduled to close on
February 18, 2008. From that point forward, gold production from the
Fosterville and Stawell mines will be attributed to Northgate. Initial
projections call for these mines to produce between 190,000 - 200,000 ounces
of gold during 2008, all of which will be sold at spot prices. Northgate will
provide further guidance on gold production, production costs, capital
expenditures and exploration costs for its newly acquired Australian assets in
March 2008.



    2008 exploration spending at Northgate's Young-Davidson property near
Matachewan, Ontario is forecast to total approximately $21 million and will be
devoted towards surface-based exploration, underground ramp development and
preparation of a feasibility study for the project.
    The surfaced-based diamond drilling program that began in 2006 will
continue with a target of completing 25,000 metres of drilling in 2008 at a
cost of $4 million. The primary goal of the surface-based drilling program
continues to be to increase the Syenite-hosted mineral resources in the region
between the Lower YD and Lower Boundary zones and within 1,300 metres of
surface (above the 9000 level). See Figure 1: Young-Davidson Property
(Vertical, North Looking, Longitudinal Section with Metric Grid) at

    Excavation of the underground ramp to its final length of 3,000 metres
will continue and is expected to be completed by June 2008. At the same time,
the underground definition drilling program, which began in the last half of
2007, will continue from upper sections of the ramp with the goal of moving
additional resources into the Indicated category. Dewatering and refurbishing
of the Existing No. 3 shaft down to the 14th level at approximately 625 metres
in depth, in order to provide ventilation and secondary access to the
underground ramp workings, will also continue.
    In January 2008, Northgate engaged AMEC to prepare a feasibility study
for the Young-Davidson project and expects the work to be largely complete
before the end of the year.


    Northgate has budgeted to spend up to $750,000 conducting limited diamond
drilling in the area immediately surrounding the Kemess South open pit in
order to test targets that were identified in a deep penetrating IP survey
completed in 2007. The purpose of this program is to identify any potential
extensions to the Kemess South ore body that could add mine life to the Kemess
operation beyond the end of 2010.
