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

Northgate Minerals Corporation (TSX: NGX) (AMEX: NXG) 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."

OVERVIEW OF YOUNG-DAVIDSON EXPLORATION AREA

Gold mineralization on the Young-Davidson property is present primarily in an intrusive syenite host rock dipping at approximately 70 degrees to the south. Figure 1, shown below, presents known resource areas (as defined in the legend), historic mine workings, simplified geology, potential new resource areas along with the pierce points for the holes drilled. Elevations in the longitudinal section are based on an artificial mine grid where the surface is defined as 10,355 metres.

Beginning in early 2008, three surface drills and one underground drill will continue with exploration. As the ramp development advances, a second underground drill rig will be added.

A new resource calculation is presently underway and will be available in January 2008, which will be incorporated into the Pre-Feasibility Study for the project.

Lower Boundary Zone

Five drill holes: YD07-42B, YD07-47A, YD07-51, YD07-53, and YD07-56 all intersected significant mineralization in the Lower Boundary zone. The results of these holes are presented in Table 1.

Drill holes YD07-42B and YD07-47A, completed between the C1 and C2 dykes, confirm the continuation of the zone in this area. YD07-42B returned 46.80 g/t gold over 9.1m and YD07-47A returned 3.91 g/t gold over 9.5m. The mineralization in hole 47A was partially cut off by a diabase dyke.

Drill hole YD07-51, completed in the upper levels of the Lower Boundary zone, returned 2.55 g/t gold over 32.2m including 7.40 g/t over 6.1m. Hole YD07-56, drilled to test the continuity of the Lower Boundary zone, returned 2.74 g/t gold over 53.5m, including 3.77 g/t gold over 17.5m.

Drill hole YD07-53 is the deepest and most westerly hole that has targeted the Lower Boundary zone. It is over 1,300m deep and about 100m west of YD06-16 and returned a thick intersection of 80.8m grading 2.68 g/t gold including 18.0m of 3.47 g/t gold. This hole confirms the Lower Boundary zone remains open at depth and has continuity towards the Lower YD zone. The results of these holes also illustrate that the Lower Boundary zone is significantly larger than previously known.

Lucky Zone

Five holes, the first drilled holes from underground, were completed targeting the Lucky zone. Hole R-02 returned 3.98 g/t gold over 29.5m including 8.65 g/t gold over 9.1m. R-03A returned 15.0m of 1.90 g/t gold including 2.4m of 3.48 g/t gold. Hole R-04 was drilled to test the west limit of the Lucky zone and did not return any significant results. Holes R-01 and R-03 were both abandoned for technical reasons before reaching target.

Lower YD Zone

Five new drill holes were completed on the Lower YD zone. The deepest hole, YD07-46A, intersected a dyke at the zone horizon and only returned 1.17 g/t gold over 41.3m of what is thought to be footwall zone.

Drill holes YD07-50, 52, 54, and 55 were completed at various levels on the west flank of the known Lower YD zone as illustrated in Figure 1. All of these holes intersected zone material. YD07-50, the lowest hole, returned 3.03 g/t gold over 24.0m including 5.54 g/t gold over 8.5m. YD07-52, completed about 380m above YD07-50, returned 1.90 g/t gold over 15.4m including 3.47 g/t gold over 3.0m. YD07-55, situated about 130m above YD07-52, returned 4.12 g/t gold over 15.6m and YD07-54, a further 100m higher, returned 2.4 g/t gold over 24.8m including 3.16 g/t gold over 11.5m.
