Rochester Receives Additional Ball Mill to Substantially Increase Mill Production

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 26, 2008) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I): Dr. Alfredo Parra, President and CEO, announces that the larger capacity 10ft x 10ft Allis Chalmers ball mill and a Symons 4 1/4 standard secondary crusher have arrived at the Mina Real mill site in Nayarit, Mexico.

The Company's plans are to utilize this equipment to increase production capacity to the 300 tpd level. This is the most efficient operating capacity given the current mine production levels.

Once installed and operational the ball mill and crusher will increase the throughput tonnage to 300 tpd level for its milling facility, a 50% increase from current capacity. Foundations for the ball mill and power supply are under construction and anticipated to be completed shortly. The Company is expecting to have the new equipment installed and operational by end of second quarter of 2008. The existing ball mills will be held as back up to be used during periods of maintenance and can also be used to augment production levels from 300 tpd up-to 500 tpd if and when the Company determines to increase throughput production.

Production at the 300 tpd level will be the most efficient production level while the company continues with its mine development programs.

The Company anticipates by the middle of 2008 to be operating at a significant increase in daily throughput while concurrently processing higher grade ore along with improved silver recovery rates. This will coincide with the processing of the silver-rich ore from the Tajos Cuates mine, the Company's second mine.

About Rochester Resources Ltd.:

Rochester represents a pure-play in the exploration and development of high-grade gold and silver properties located in Nayarit, Mexico. The Company is a niche player in Mexico which has assembled an attractive portfolio of properties in the Sierra Madre Occidental Range. This is the largest epithermal precious metal region in the world, hosting the majority of Mexico's large tonnage gold and silver deposits. Current production generates growing cash flow and helps fund our ongoing exploration and development with minimum share dilution (http://www.rochesterresources.com/investors.aspx).

We have identified 36 vein structures (http://www.rochesterresources.com/projects.aspx) on our two Projects (Mina Real and Santa Fe) and recently embarked on an aggressive follow-up exploration program including a 7000m drill program and a 2000m drift development program that will determine the next steps for mine development and production levels. Little follow-up work has been completed to date on the vein structures identified across both Projects.

Rochester is well positioned to advance its Projects and can very quickly become a significant player in Mexico. Rochester has a strong senior management team (http://www.rochesterresources.com/comDirectors.aspx) based in Mexico, a workforce in place to advance its projects through to mine development, and strong financial backing to implement and advance our work programs.

ON BEHALF OF THE BOARD
