Northgate Reports Record Gold Production; 2004 Cash
Cost of $137 Per Ounce

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 10, 2005) - Northgate
Minerals Corporation (TSX:NGX)(AMEX:NXG) - (All figures in US dollars
except where noted)

Northgate Minerals Corporation today reported record quarterly and
annual operating results from the Kemess mine located in north central
British Columbia.

2004 Highlights

- Record annual gold production of 303,475 ounces

- Record quarterly gold production of 94,673 ounces in the fourth quarter

- Record annual copper production of 78.3 million pounds

- Record quarterly copper production of 23.9 million pounds in the
fourth quarter

- Record low annual cash cost of $137 per ounce

- Record low quarterly cash cost of $116 per ounce in the fourth quarter

- Record quarterly mill throughput record for hypogene ore of 52,136
tonnes per day

- Record annual mining productivity of 826 tonnes moved per man shift

Ken Stowe, President and CEO, commented, "The Kemess mine finished the
year extremely strongly, setting records for quarterly gold and copper
production and recording the lowest quarterly cash cost in the history
of the mine. I wish to acknowledge the efforts of each and every one of
our employees who worked together to achieve these significant
accomplishments. 2004 marks the fifth year in a row that annual metal
output at Kemess has increased. I am especially pleased to report that
for the third year in a row, we delivered the metal production that we
forecast to our shareholders at the beginning of the year and did so at
a cash cost of only $137 per ounce."

Overview of Operations

The Kemess mine posted record gold and copper production of 94,673
ounces and 23.9 million pounds respectively, in the fourth quarter of
2004. This record production was the result of record mill throughput
for hypogene ore of 52,136 tonnes per day combined with above-average
ore grades. Over the course of 2004, ore grades and quarterly metal
production varied considerably as different areas of the Kemess pit were
mined as scheduled. For the full year, the grade of ore milled was close
to the Kemess South reserve grade and metal production was consistent
with the forecast released by Northgate at the beginning of 2004.

The cash cost of production at Kemess in the fourth quarter was $116 per
ounce bringing the average 2004 cash cost to $137 per ounce. Both these
figures represent records for the Kemess mine. Record copper production
and strong copper prices, which averaged $1.40 per pound for the fourth
quarter and $1.30 per pound for the full year, generated these excellent
results in spite of the strengthening Canadian dollar and the unusually
large amount of waste stripping (1.9:1 versus the life of mine average
of 1:1) that was completed during the year. Using the Gold Institute
methodology, which many other gold companies use, cash costs at Kemess
were $70 per ounce in the fourth quarter and $83 per ounce for the
entire year.

Northgate's audited financial results for the year ended December 31,
2004 are scheduled for release on February 24, 2005 and the
Corporation's regular quarterly investor conference call will be held at
10 am (Eastern Standard Time) the following day.
