Northgate Minerals Receives Key Permit for the Development of the
Young-Davidson Mine

Construction Set to Begin in August

VANCOUVER, July 2 /CNW/ - (All figures in US dollars except where noted) Northgate Minerals Corporation ("Northgate") (TSX: NGX, NYSE Amex: NXG) is pleased to announce that it has received notice from the Ontario Ministry of Northern Development, Mines and Forestry ("MNDMF") of acceptance of the Closure Plan for the Young-Davidson Mining Project. Acceptance of the Closure Plan allows Northgate to commence construction and development of the Young-Davidson mine, which is forecast to produce an average of 180,000 ounces of gold per year at a cash cost of $350 per ounce over a 15-year mine life starting in 2012.

Ken Stowe, President and CEO, commented: "We are extremely pleased that our Closure Plan has been accepted by the MNDMF and we will be proceeding with construction of the Young-Davidson mine as soon as the appropriate resources have been mobilized. Young-Davidson is an important project for northern Ontario, providing significant economic and social benefits for the local and surrounding communities. We look forward to breaking ground in early August, with advanced preparatory work having positioned us well to achieve our key scheduled objectives. In addition to the work that is underway at site, our exploration team has already completed over 11,600 metres of diamond drilling this year and results to date indicate the strong potential for us to expand the current 2.8 million ounce reserve."

The Closure Plan sets out the framework for the development, operation and ultimate closure of the Young-Davidson mine and outlines the plans for rehabilitation of those areas affected by historic and future mining. Construction of the main process building for Young-Davidson is scheduled to commence in early August and the mill building is expected to be enclosed by the end of the year, so that construction of the process plant can continue during the winter months. Other projects scheduled to begin in the coming months are the deepening of the existing shaft, construction of the tailings impoundment area and the realignment of Highway 566.

Over $140 million of contracts for the development of the mine have already been awarded including the engineering, procurement and construction management ("EPCM") contract, the shaft deepening and raise boring contract and a contract for upgrading the existing 47 kilometre ("km") transmission line connecting Young-Davidson to the provincial grid. Additional contracts have been tendered and are currently being reviewed. Purchase orders have also been awarded for major, long lead equipment.

Northgate will provide a more detailed update on construction activities at Young-Davidson during its second quarter conference call and webcast that will be held on August 10, 2010.

Young-Davidson is located near the town of Matachewan, 60 km west of Kirkland Lake. Northgate completed its final feasibility study for Young-Davidson at the beginning of the year (see press release dated January 25, 2010), which confirmed that the mine provides strong returns in the current economic environment. Using today's spot prices, the mine is expected to generate $2.2 billion pre-tax operating cash flow, a pre-tax net present value 5% of $865 million and a pre-tax internal rate of return of 25%.

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 310,000 ounces in 2010.

Cautionary Note to US Investors Regarding Mineral Reporting Standards:

Northgate prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this press release are defined in accordance with National Instrument 43-101-Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Standards on Mineral Resources and Mineral Reserves.
