        $350 per ounce over a 15-year mine-life.

    -   Pre-tax cash flow of $1.2 billion, net present value ("NPV") 5% of
        $609 million, with an internal rate of return ("IRR") of 20.3% at
        today's spot prices of $1,070/oz gold and exchange rate of US$/Cdn
        $0.93.

    -   Employment for 600 people during the two year construction period and
        direct employment for 275 people over the life of the mine.

Ken Stowe, President & CEO, stated "Young-Davidson represents an integral part of our growth platform and fits our vision of developing and operating profitable and long-life operations in politically predictable, mining friendly jurisdictions. We are extremely pleased to be moving ahead with the project with the full support of our board and look forward to a formal celebration in the coming weeks to commemorate this important milestone. With construction slated to begin later this year, we expect to begin producing gold at Young-Davidson in 2012, creating sustainable and long-term value for our shareholders through disciplined growth and operational excellence."

Approval by Northgate's board of directors for the development of the Young-Davidson mine follows the positive results of the recently completed AMEC Feasibility Study (refer to press release dated January 25, 2010). Dewatering of the existing shaft and driving of the existing exploration ramp past 523 metres vertical have recommenced at site. Detailed engineering for the mill facility will begin shortly and construction of surface and shaft facilities is scheduled to begin this summer once the applicable approvals are received. In addition, Northgate plans to enter into agreements with respect to engineering, procurement and construction management ("EPCM") and deepening of the existing shaft and construction of a new production shaft in the coming weeks.

Development of the Young-Davidson mine will provide jobs for 600 people during the two year construction phase of the project and ongoing direct employment for 275 people during the operating life of the mine. Substantial economic benefits will accrue to the communities closest to the mine, including the towns of Matachewan, Elk Lake, and Kirkland Lake. Manufacturers, suppliers and contractors in these nearby towns as well as those in the regional centres of Timmins, North Bay and Sudbury will have the opportunity to share in the $339 million invested during the construction phase and annual expenditures on goods and services of approximately $50 million during the life of the mine.

Northgate Minerals Corporation is a gold and copper producer with mining operations, development projects and exploration properties in Canada and Australia. Our vision is to be the leading intermediate gold producer by identifying, acquiring, developing and operating profitable, long-life mining properties. We are forecasting gold production of 316,000 ounces in 2010.
