Northgate Minerals Corporation (TSX:NGX)(NYSE Amex:NXG) is pleased to announce that our Kemess South Mine has been awarded the 2010 Mining and Sustainability Award from the Mining Association of British Columbia (MABC) and the Ministry of Energy and Mines. The award was given out at this year's Mining Week Celebration held in Smithers, British Columbia.

"We are honoured to receive the 2010 Mining and Sustainability Award for our efforts at the Kemess South Mine" commented Harold Bent, Environmental Manager, Northgate Minerals Corporation. "We are very proud of our accomplishments in all aspects of our operation, including environment, employee and community engagement and production. More importantly, these accomplishments were achieved while maintaining the highest standards of safety and the environment. We would like to thank the MABC and the Selection Committee for this award in recognition of our achievements in responsible mining practices at the mine."

The Mining and Sustainability Award is a joint initiative of the MABC and the Ministry of Energy and Mines. Launched in 2005, the annual sustainability award recognizes groups and individuals who are committed to advancing and promoting sustainable development and responsible mining practices in the BC exploration and mining sector.

"As the mining sector embarks on a period of growth not seen in a generation, it is more important than ever to find new and better ways to dig the minerals that are critical to a clean and green economy out of the ground" stated Pierre Gratton, President and CEO of MABC. "This award is intended to celebrate those new and better ways and it is an honour to recognize both of this year's recipients for their leadership."

Responsible Mining Practices

At Northgate, our objective is to minimize our environmental footprint through implementing environmentally responsible practices through all phases of the mine-life cycle and to provide protection for the environment today and for future generations. We view effective management of the environmental effects of our operations as critical to our success as an organization. As Kemess South is being decommissioned, more than 60% of the land has already been reclaimed. Major reclamation efforts include:

  • Completion of reclamation on the Tailings Dam downstream buttress zone;

  • Over 95% completion of reclamation of the Waste Rock Dump;

  • 100% completion of re-handle of the Ex-Pit PAG (potentially acid generating) waste rock into the open pit for permanent underwater disposal, with placement of overburden having been completed over the entire base pad;

  • Over 70% completion of clean up of temporary ore stockpile pads, with the remainder to be completed with overburden placement by end of summer 2011;

  • Placement of overburden, while clean up of stockpile and waste rock bases commence this summer;

  • Construction activity on the spillway, which is scheduled for completion in the fall; and

  • Development of a detailed pre-closure and post-closure monitoring and reporting program, which evaluates the success of vegetation growth and establishment, continued fish presence and utilization, water quality, long-term stability and safety of the closed site to ensure long-term reclamation success is achieved.

About the Kemess South Mine

Northgate has owned and operated the Kemess South Mine since 2000, transforming the operation into one of the most successful mines ever built in Canada. Mine production ended in March 2011, generating close to three million ounces of gold and 700 million pounds of copper.

Kemess South has been recognized as a leader in mining reclamation practices. In addition to the 2010 Mining and Sustainability award, the mine has also been awarded back-to-back Citations by the BC Technical & Research Committee in 2008 and 2009. This is the third time in the last nine years that the mine has been recognized for its outstanding and innovative reclamation efforts.

Cautionary Note to US Investors Regarding Mineral Reporting Standards:

The Corporation prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of US 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. The Securities and Exchange Commission (the "SEC") permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. The Corporation uses certain terms, such as, "measured mineral resources", "indicated mineral resources", "inferred mineral resources" and "probable mineral reserves", that the SEC does not recognize (these terms may be used in this press release and are included in the Corporation's public filings which have been filed with securities commissions or similar authorities in Canada).
