Northgate Announces Additional Drill Results for the Young-Davidson Project

Northgate Minerals Corporation is pleased to report drill results for 34 surface and 59 underground diamond drill holes totalling 33,000 metres, which were completed during the first half of 2008 at the Young-Davidson project near the town of Matachewan in northern Ontario. The purpose of the ongoing diamond drill program is to increase the measured and indicated resource base at Young-Davidson in preparation for completion of a Feasibility Study and to increase the total resources on the property.

Drilling Highlights

– Diamond drilling in 2008 has confirmed that the four previously established resource zones (the Upper Boundary, Lower Boundary, Lucky and Lower YD zones) form a near continuous gold system of overlapping lenses cut by numerous post mineral dykes. – A new area of mineralization has been discovered adjacent to the historic Young-Davidson workings. – Holes 75 and 75A, drilled down dip on the Upper Boundary zone to test grade continuity of that zone, intersected 4.17 grams per tonne (g/t) gold over 123.5 metres (m) and 4.12 g/t gold over 350.0m, respectively. – Hole 62 (Upper Boundary zone) intersected 3.79 g/t gold over a broad width of 73.9m (56.6m true thickness) including 6.05 g/t gold over 9.5m. – Hole 56A (Lower Boundary zone) intersected 3.51 g/t gold over an exceptional width of 130.2m (94.1m true thickness). – Hole 78 (Lower YD zone) intersected 7.90 g/t gold over 28.1m (19.7m true thickness). – A cross cut driven in the upper portion of the Upper Boundary zone to collect a bulk sample for metallurgical testing averaged 5.0 g/t gold over a true thickness of 41m. Grinding testwork indicates that this material is amenable to low cost autogenous grinding.

– Underground definition drilling has confirmed the continuity and geometry of the upper portion of the Upper Boundary Zone.

Ken Stowe, President and Chief Executive Officer, remarked, “This year’s drilling program at Young-Davidson has been highly successful. The various zones have now essentially been joined into one large continuous gold bearing system. Although the focus of this year’s drill program has been mainly on converting inferred resources to measured and indicated, the drilling we have completed to date has also identified areas of previously unknown mineralization, which will increase the total resource base when the next resource update is completed later this year in conjunction with the project’s feasibility study. Also of note, pilot plant testing of a bulk sample taken from the Upper Boundary Zone has confirmed that the ore is amenable to low cost autogenous grinding (i.e. no steel balls required). All of these factors will have a positive impact on the final economics of the Young-Davidson project.”
