VANCOUVER, Jan. 28 /PRNewswire-FirstCall/ -- (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. 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." RESULTS OF OPERATIONS 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, respectively. The cash cost of production at Kemess in the fourth quarter was $48 per ounce bringing the average 2007 cash cost to negative $16 per ounce. Northgate's audited financial results for the year ended December 31, 2007 are scheduled for release on February 28, 2008 and the Corporation's year-end conference call and webcast for investors and analysts will be held at 10:00 am (Eastern Standard Time) on the following day. The following table provides a summary of operations for the fourth quarter and the full year of 2007 and the comparable periods of 2006. 2007 Kemess Mine Production (100% of production basis) Q4 2007 Q4 2006 2007 2006 ------------------------------------------------------------------------- Ore plus waste mined (tonnes) 8,042,000 11,018,461 42,025,404 43,045,348 Ore mined (tonnes) 3,206,000 4,746,251 17,060,785 17,219,143 Stripping ratio (waste/ore) 1.51 1.32 1.46 1.50 Ore milled (tonnes) 4,238,626 4,567,332 17,802,317 18,233,978 Ore milled per day (tonnes) 46,072 49,645 48,773 49,956 Gold grade (gr/mt) 0.459 0.772 0.627 0.763 Copper grade (%) 0.238 0.243 0.214 0.244 Gold recovery (%) 66 72 68 69 Copper recovery (%) 75 87 81 83 Gold production (ounces) 41,467 81,747 245,631 310,296 Copper production (thousands pounds) 16,766 21,255 68,129 81,209 Tonnes mined per shift worked 449 645 589 693 Tonnes milled per shift worked 237 267 249 277 Net cash cost ($/ounce)(1) 48 (90) (16) (56) ------------------------------------------------------------------------- ------------------------------------------------------------------------- Note 1: 2007 cash cost figures are unaudited estimates and are subject to revision. 2008 PRODUCTION FORECAST 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 (
