NORTHGATE CONTINUES TO INTERSECT HIGHER GRADE GOLD INTERVALS AT YOUNG-DAVIDSON; US$28 MILLION PROGRAM PLANNED IN 2007

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 30, 2006) - Northgate Minerals Corporation (TSX:NGX)(AMEX:NXG) today announced assay results for eight additional diamond drill holes at its Young-Davidson property near the town of Matachewan, Ontario.

Exploration Highlights

- Hole 23 in the Lower YD Zone intersected 31.1 metres averaging 3.70 grams per tonne (gpt) gold, including 6.7 metres of 7.14 g/t.

- Hole 21A in the Lower YD Zone returned 3.66 g/t gold over 33.2 metres including 9.8 metres of 6.30 g/t.

- Hole 20C in the Lower Boundary Zone returned 4.14 g/t gold over 36.7 metres including 8.33 g/t over 8.4 metres.

- Hole 16C in the Lower Boundary Zone 3.26 g/t gold over 20.6 metres including 5.8 metres of 5.95 g/t.

Ken Stowe, President and Chief Executive Officer, remarked, "Our most recent drill results continue to demonstrate the considerable potential of the Young-Davidson property. Both the Lower Boundary Zone and Lower YD Zone are continuing to develop nicely in a manner that will support low-cost bulk mining. Due to the significance of the most recent assay results, we have decided to include them in the NI 43-101 resource estimate that we had originally expected to release by the end of November. As a result of this decision, the release of the updated resource estimate will be delayed until the middle of December."

"Looking forward to 2007, we have budgeted US$28 million for work at Young-Davidson, which will include the construction of an underground ramp, dewatering of the existing No. 3 shaft, and exploration drilling and various engineering studies that will form the basis for a pre-feasibility study that we expect to complete by the end of the third quarter. Our project team has recently awarded the contract for underground ramp development and shaft dewatering and mobilization of men and material has already begun."

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 underground resource areas (darker shaded areas), potential new resources defined by 2006 drilling (lighter shaded areas),historic mine workings and simplified geology along with the pierce points for the holes drilled so far this year. Elevations in the longitudinal section are based on an artificial mine grid where the surface is defined as 8,000 feet.

DRILLING RESULTS

Collar co-ordinates for the reported drill holes are listed in Appendix 1 and assay results for selected mineralized intervals are reported in Tables 1 and 2.

Lower YD Zone

Hole YD06-21A intersected 113.2 metres averaging 1.78 g/t gold. Toward the bottom of this interval a 33.2 metre section averaged 3.66 g/t including 16.5 metres of 4.62 and 9.8 metres of 6.30 g/t. This hole intersected the zone about 55 metres up-dip from Hole 21. The similarity in spatial location, thicknesses and grades to Hole 21 confirms the continuity of the gold mineralization in this area.

Holes YD06-23 and 24 were drilled on either side of Hole 22 on the 5,400 level. Hole 23, the most westerly hole drilled to date, returned 3.70 g/t gold over 31.1 metres including 15.9 metres of 4.75 g/t and 6.7 metres of 7.14 g/t. Hole 24 to the east of Hole 22 intersected a 79.3 metre thick section averaging 1.58 g/t. In Hole 24, two zones are present, an upper zone of 13.1 metres grading 3.73 g/t including 4.2 metres of 8.32 g/t and a lower zone of 7.6 metres grading 3.66 g/t gold.

Hole YD06-25 was drilled about 80 metres east of Hole 24 in an attempt to define the eastern extent of the Lower YD Zone. The drill hole intersected an upper zone of 3.02 g/t Au over 6.1 metres and a lower zone of 1.01 g/t Au over 27.5 metres including 2.38 g/t Au over 4.3 metres.

Holes YD06-21B and 21C were abandoned due to technical difficulties.

The intersections in Holes 17, 17B, 21, 21A, 22, 23 and 24 outline a mineralized body 150 metres along strike, 5 to 30 metres thick and at least 400 metres down-dip. The Lower YD Zone remains open to the east, west and at depth.

Lower Boundary Zone

Hole YD06-16C intersected 2.15 g/t gold over 58 metres including 20.6 metres of 3.26 g/t and 5.8 metres of 5.95 g/t. This hole is a wedge deflection from Hole YD06-16 and intersected the Lower Boundary Zone 140 metres above and 60 metres east of the parent hole, and 30 metres below and 10 metres west of Hole 16A. This hole also intersected a hanging wall zone that assayed 4.08 g/t gold over 4.9 metres.

Drill Hole 20A, the deepest drill hole on the property to date, returned 2.35 g/t gold over 19.2 metres including 7.8 metres of 4.47 g/t. Due to a problem during drilling 2.3 metres of core from this high-grade interval were not recovered.

Hole 20B returned 53.4 metres of 1.85 g/t gold including 28.9 metres of 2.08 g/t, 16.1 metres of 2.27 g/t and 3.1 metres of 3.77 g/t.

Hole 20C returned 36.7 metres of 4.14 g/t gold including 17.7 metres of 6.04 g/t within which there was an 8.4 metre interval of 8.33 g/t.

Hole 16B deviated too far to the east and intersected a dyke at the mineralized zone level and did not return any significant assays.

Drilling to date suggests the Lower Boundary Zone is at least 275 metres along strike, 5 to over 30 metres thick and over 300 metres down-dip. The zone remains open to the east, west and at depth.
