Northgate Announces Additional Young-Davidson Drill Results - Drill Hole YD07-42B Returns 46.80 Grams per Tonne Gold Over 9.1 Metres

VANCOUVER, British Columbia, Dec 20, 2007 (BUSINESS WIRE) -- Northgate Minerals Corporation (CA:NGX) (NXG: Northgate Exploration Limited) today announced assay results for 13 additional diamond drill holes at its Young-Davidson property near the town of Matachewan, Ontario.

DRILLING HIGHLIGHTS

- Hole YD07-42B, on the eastern flank of the Lower Boundary
zone, intersected 46.80 grams per tonne (g/t) gold over
9.1 metres (m).

- Hole YD07-53, also targeting the Lower Boundary zone,
intersected 80.8m of 2.68 g/t gold including 3.47 g/t gold
over 18.0m. This hole is situated below and about 100m
further to the west than any other intersection in the area.

- Hole YD07-50, drilled on the western flank of the Lower YD
zone, returned results of 5.54 g/t gold over 8.5m.

- The results of these latest holes are being incorporated into
a resource update for the project, which is expected to be
completed in January 2008.

Ken Stowe, President and Chief Executive Officer, remarked, "The exploration team at Young-Davidson continues to achieve outstanding results. The continuity of the mineralization in the four main zones is excellent, which supports our concept of low-cost, large-scale bulk underground mining for the project. Given the drilling success in 2007, we expect to see another significant increase in gold resources for the project once the new resource update is completed next month, which will have a positive impact on the Pre-Feasibility Study for the project."

Ryan Freund submits:
The price-to-earnings-growth [PEG] ratio is primarily a growth investing metric that measures the price-to-earnings ratio in relation to the growth rate the company will experience in the future. This metric is useful for determining if a company is under-valued when compared to its expected growth rate. Many growth investors use this figure when performing research, but few value investors believe it yields any useful information. The problem value investors have with this metric is that it relies on estimates of future growth. Value investors prefer hard facts, not estimates. Here at Freund Investing, however, we believe that the value investing methodology taught by Ben Graham and Warren Buffett can be enhanced by including certain growth metrics, including the PEG ratio.
As important as the PEG ratio is, it cannot be completely relied upon for investment selections. Rather, it should be used as one portion of the overall picture. Investments with low PEG ratios are often undervalued to begin with, and present a great source of investments which should be researched further. The following are the lowest 15 PEG ratios of all investments listed on the most common exchanges. The investment with the highest PEG ratio, Primus Guaranty, has a PEG of merely 0.27. The lowest is seen at Security Capital, with a PEG of only 0.11.

VANCOUVER, Jan 18, 2008 /PRNewswire-FirstCall via COMTEX/ -- Northgate Minerals Corporation (CA:NGX) (NXG: Northgate Exploration Limited) is pleased to announce that the common shareholders and warrant holders (referred to in Australia as ordinary shareholders and optionholders, respectively) of Perseverance Corporation Limited ("Perseverance") voted earlier today in favour of their respective Schemes of Arrangement (the "Schemes"), which will give effect to Northgate's acquisition of Perseverance. These votes follow the previous approval received from Perseverance noteholders on December 17, 2007. Approval by the Supreme Court of Victoria of the Schemes is necessary before proceeding with the acquisition and a hearing is scheduled for February 1, 2008. Subject to that approval, implementation of the Schemes is scheduled to occur on February 18, 2008.
Ken Stowe, Northgate's President and CEO, commented, "Today's approval of the Schemes by the shareholders and warrant holders of Perseverance represents a watershed event in what has been a lengthy but ultimately rewarding process that will benefit shareholders and employees of both companies. Our integration plans for Perseverance are well advanced and both of our management teams are very excited about the bright future of the Fosterville and Stawell mines as part of the Northgate family. Once the transaction closes in mid-February, Northgate will emerge as an unhedged, multi-mine gold producer with a strong balance sheet, excellent cash flow and tremendous growth potential, with operations in stable, mining-friendly jurisdictions of Canada and Australia."

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

FOURTH QUARTER 2007 HIGHLIGHTS

- 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 acquisition."

Underground Resources Now Total 1.86 Million Ounces TSX NGX AMEX NXG

VANCOUVER, Feb 06, 2008 /PRNewswire-FirstCall via COMTEX/ -- Northgate Minerals Corporation (CA:NGX) (NXG: Northgate Exploration Limited) is pleased to report the results of a new underground mineral resource estimate at its Young-Davidson property near Matachewan, Ontario. The estimate combines the results of the 2007 diamond drill program with historic drilling data. A re-estimate of the indicated resources mineable by open pit methods, incorporating the results of a recently completed infill drilling campaign, is presently underway and will be released at a later date.

EXPLORATION HIGHLIGHTS

- Total gold resources on the property including those mineable by open
pit methods is now 2.34 million ounces

- Total underground gold resources in the four main ore zones have
increased to 1.86 million ounces

- Indicated resources underground have increased to 1.42 million
ounces, a gain of 137% compared to last year's estimate

- The percentage of total resources underground in the indicated
category has increased from 36% to 76%

- Vertical continuity of the zones has been established to a depth of
1,350 metres below surface

- Horizontal continuity on two levels between the two historic mines
has now been demonstrated by drill intersections

Ken Stowe, President and CEO, commented, "Since we acquired the Young-Davidson property two years ago, we have essentially achieved our goal of doubling the underground gold resource base. We have clearly established that there are large areas of continuous mineralization both between and below the workings in the two historic mines. An equally important objective has been the conversion of inferred resources to the indicated category and we are very pleased that we now have 1.4 million indicated ounces underground with more to come in 2008. The first priority of our 2008 diamond drill program will be to increase the indicated ounces underground by an additional 0.5 million ounces focusing the drilling in the prospective areas between the two Boundary Zones and the Lucky/Lower YD Zones. Maximizing the number of indicated resource ounces is important as it is these ounces that can be converted into reserves in the upcoming Feasibility Study. The tight spatial distribution of the resources on the property will be beneficial in minimizing the required underground infrastructure."

Completes acquisition of Australian-based gold miner

VANCOUVER, Feb 28, 2008 /PRNewswire-FirstCall via COMTEX/ -- (All figures in US dollars except where noted) - Northgate Minerals Corporation (CA:NGX) (NXG: Northgate Exploration Limited) today reported cash flow from operations of $32,914,000 or $0.13 per diluted common share and net earnings of $32,020,000 or $0.13 per diluted common share for the fourth quarter of 2007. Cash flow from operations for all of 2007 was $125,285,000 or $0.49 per diluted common share and net earnings were $38,136,000 or $0.15 per diluted common share.

Fourth Quarter Highlights

- On October 29, 2007, Northgate announced its proposal to acquire
Perseverance Corporation Ltd. ("Perseverance"), an Australian gold
producer with two fully-permitted gold mines. The deal was approved
by Perseverance securityholders and closed on February 18, 2008.
- Northgate closed out its gold hedge book and is now completely
exposed to future gold price changes.
- Production of 41,467 ounces of gold and 16.8 million pounds of copper
from the Kemess South mine.
- Quarterly gold net cash cost of $18 per ounce and an annual net cash
cost of negative $22 per ounce of gold for all of 2007.

Ken Stowe, President and CEO, stated, "All in all, 2007 was another solid production year at Kemess despite a significant modification to the production schedule in the fourth quarter, which was necessitated by the realignment of the main haul road out of the pit. Strong cash flow from operations of $125 million for the year continued to strengthen an already strong balance sheet, thereby allowing us to complete the acquisition of Perseverance with no shareholder dilution. With the closing of the Perseverance deal, we have now achieved a key strategic objective and transformed Northgate into a multi-mine 400,000-ounce per year gold producer with all of our operations in stable jurisdictions. With unhedged gold and copper production in 2008 and record or near-record prices for both metals, we are well positioned for another strong year of cash flows. This will give us the ability to make strategic investments at our new Australian operations while continuing to aggressively develop the Young-Davidson project and look for additional growth opportunities."
Results of Operations
Northgate recorded net earnings of $32,020,000 or $0.13 per diluted share in the fourth quarter of 2007 compared with $19,790,000 or $0.09 per diluted share during the corresponding quarter of 2006. For the full year 2007, net earnings were $38,136,000 or $0.15 per diluted share compared with $106,742,000 or $0.48 per diluted share in 2006. Earnings for the fourth quarter and the full year of 2007 included non-cash future income tax recoveries of $2,267,000 and $13,065,000, respectively. Cash flow from operations, after changes in working capital and other items, was $32,914,000 or $0.13 per diluted share in the fourth quarter of 2007 compared with $43,884,000 or $0.20 per diluted share during the same quarter last year. For the full year 2007, cash flow from operations after changes in working capital and other items was $125,285,000 or $0.49 per diluted share compared with $146,612,000 or $0.66 per diluted share in 2006. Per share data is based on the weighted average diluted number of shares outstanding of 255,065,987 and 255,257,756 in the fourth quarter and full year of 2007, respectively. The weighted average diluted number of shares outstanding in the corresponding periods of 2006 was 224,674,332 and 222,892,929, respectively.
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 all of 2007, Kemess posted gold and copper production of 245,631 ounces and 68.1 million pounds, respectively.
During the fourth quarter of 2007, approximately 8.0 million tonnes of ore and waste were removed from the open pit compared to 11.0 million tonnes during the corresponding quarter of 2006. As a result of the lower tonnes mined, unit mining costs during the current quarter were unusually high at Cdn$2.37 per tonne compared with Cdn$1.64 per tonne in the same period of 2006. For the full year 2007, mining costs averaged Cdn$1.76 per tonne mined compared with Cdn$1.49 per tonne in 2006.
Mill availability during the fourth quarter of 2007 averaged 90% and throughput averaged 46,072 tonnes per day (tpd), compared with 91% availability and throughput of 49,645 tpd in the fourth quarter of 2006. Mill throughput was lower in the most recent quarter than it was one year ago due to a variety of operating problems related to processing higher moisture supergene ore from stockpile during the colder winter months. 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 mill availability averaged 91%, which was the same as 2006.
Gold and copper recoveries averaged 66% and 75%, respectively, in the fourth quarter of 2007 compared with 72% and 87% in the fourth quarter of 2006. Copper recoveries were significantly lower in the fourth quarter of 2007 than they were in the same quarter of 2006, due to the large quantity of very unusual, high native copper supergene ore with inherently lower copper recovery that was milled from the stockpile in November and December. For the full year, gold and copper recoveries were 68% and 81%, respectively, compared with 69% and 83% in 2006.
Metal concentrate inventory decreased by 1,000 wet metric tonnes (wmt) to approximately 6,000 wmt during the fourth quarter of 2007. Concentrate inventory is expected to decline through 2008.
The total unit cost per tonne milled during the fourth quarter of 2007 was Cdn$13.16 (2006 - Cdn$15.58), including Cdn$3.31 (2006 - Cdn$6.48) for marketing costs, which was comprised mainly of treatment and refining costs and transportation fees. The primary reason for the decline in unit cost is the reduction in treatment and refining costs, which are remitted to Xstrata Canada Corporation. Total site operating costs in the fourth quarter of 2007 were Cdn$41.9 million, consistent with costs of Cdn$41.6 million in the fourth quarter of 2006. The net cash cost of production at Kemess in the fourth quarter was $18 per ounce, bringing the average 2007 cash cost to negative $22 per ounce. The net cash cost of gold production for the full year is negative due to the large by-product credit derived from copper production, which is credited against site operating costs for purposes of calculating cash costs.
