Zone averages 30 metres thick at 3.72 grams per tonne
VANCOUVER, Sept. 15, 2011 /PRNewswire/ - Northgate Minerals Corporation (TSX: NGX, NYSE Amex: NXG) is pleased to announce a new, NI 43-101 compliant resource estimate for the YD West zone at Young-Davidson in northern Ontario. YD West is the most recent gold zone discovery located just west of the currently known 2.8 million ounce reserve1. The Young-Davidson mine is scheduled to commence production in early 2012.
YD West Resource Highlights
"This is an outstanding result and achievement by our exploration team and we are extremely pleased with the initial resource estimate reported today" commented Richard Hall, President and Chief Executive Officer of Northgate. "The YD West zone has yielded some of best grade-thickness intervals ever drilled on the property and the initial resource has exceeded our expectations. Due to its thickness and grade, YD West has the potential to be the lowest cost per ounce mining zone on the property and will have a positive impact on the economics of the Young-Davidson mine. As we continue to explore in this zone and commence step-out drilling, the exploration upside is tremendous and we fully expect to announce a significant increase in resources at YD West by the end of the year."

YD West Zone | Tonnes (000's) | Gold (ounces) | Gold Grade (g/t) |
Indicated Resource | 4,488 | 536,000 | 3.72 |
Inferred Resource | 508 | 53,000 | 3.22 |
Notes to Minerals Resources
Overview of the YD West Zone Drill Program
The purpose of the 2011 diamond drill program on the YD West zone is to explore for new resources located west of a major north-south trending diabase dyke that appeared to have truncated and displaced the main Young-Davidson orebody. Northgate resolved the fault displacement with Discovery Hole YD10-198, which intersected 3.46 g/t over 79.5 metres ("m"). The 2011 initial resource estimate captures all drilling completed to the end of August 2011 and is based upon a total of nine drill holes, all of which have been released previously.
The resource occurs in an area of complex post-mineral dykes (Figure 2), which necessitated drilling three oblique holes in a north-west direction in order to resolve this complexity and ensure the accuracy of the resource estimation. Analytical results have been received for one of the three oblique holes while geologic results have been received for two of the three holes, providing tight control on the positions of the dykes in the YD West resource area.
In total, the Young-Davidson property now contains Proven and Probable Reserves of 2.8 million ounces of gold, Indicated Resources of approximately 550,000 ounces and Inferred Resources of over 700,000 ounces (see Annual Report for year ended December 31, 2010 for Young-Davidson Mineral Resources).
Two diamond drills will continue to focus in this area until the end of the year, with obvious expansion possible to the west at similar elevations. An updated resource for the YD West zone will be released with the Corporation's annual resource/reserve statement in the first quarter of 2012.
On the eastern side of the Young-Davidson property, underground exploration has begun on the down dip area beneath the Upper Boundary Zone (a 100 m wide sector between two prominent dykes inside the oval outline in Figure 1), where it was historically challenging to drill targeted holes from surface. The underground access that is now available from the bottom of the new ramp provides the opportunity to begin this program and three holes are already complete with assays pending. An additional eight to ten holes are planned during the balance of the 2011 exploration program.
