Mr. Hall brings to Northgate over 35 years of mining exploration and development experience and has been a member of Northgate�s board of directors since 2008. Previously, Mr. Hall served as President and CEO of Metallica Resources Inc., where he was responsible for the financing, construction and commissioning of the Cerro San Pedro gold-silver mine in Mexico. Mr. Hall was also involved in the discovery and development of the El Morro deposit located in Chile through to a final feasibility study. In August 2008, Metallica was part of a $1.6 billion merger with Peak Gold Ltd. and New Gold Inc. Previous to his tenure at Metallica, Mr. Hall held senior management positions with Dayton Mining Corporation and Pegasus Gold Corporation.

In welcoming the appointment, Terry Lyons, Northgate�s Chairman of the Board, stated: "We are extremely fortunate to have someone of Ritch�s calibre join the Northgate team. He has a proven ability to lead top performing companies and has a strong track record in driving shareholder value. We believe Ritch will use his leadership strengths and extensive mining background to take the company to the next level."

"I am excited to be part of this organization and build upon our strong core of assets" stated Mr. Hall. "With a growing production profile from Young-Davidson and the exciting Kemess Underground project in the pipeline, Northgate has a bright future. It�s a great honour to join this team as we look to execute on our strategic objectives and to grow the company and shareholder value."

This appointment follows on the previously-announced retirement of Mr. Ken Stowe as Northgate�s President and CEO. In conjunction with his retirement, Mr. Stowe has also stepped down from the board of directors effectively immediately.

Terry Lyons also paid tribute to Mr. Stowe upon the announcement of his retirement, noting: "For the past 12 years, Ken has worked tirelessly to achieve the growth of the company. Under Ken�s leadership, he has assembled one of the most experienced operating teams in the industry that has seen the transformation of Kemess South into one of the most successful mines built in Canada and the extraordinary development of Young-Davidson, which will become the new cornerstone of the company. Throughout his tenure, Ken has inspired us with his tenacity and strategic thinking and the board of directors would like to recognize and express our gratitude for his service over the years."

Mr. Hall joins the company as it enters the final nine months of construction of the Young-Davidson mine. Targeting its first gold pour late in the first quarter of 2012, Young-Davidson continues to make excellent progress and remains on schedule and on budget. In addition, erection of the mill building has been completed and the installation of process equipment will begin shortly. Development activities underground have also made excellent progress, ramping up to a record average development rate of 15 metres per day in June.

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.
