(TSXV: RCT; OTCBB: RCTFF AND FRANKFURT: R5I): Dr. Alfredo Parra, President and CEO, is pleased to announce the Company has ordered a larger capacity 10 ft x 10 ft Allis Chalmers ball mill as well as a Symons 4 1/4 standard secondary crusher to increase the throughput tonnage to 300-350 tpd level for its milling facility. This new equipment is scheduled to arrive on site in January 2008. Foundations for the mill and power supply should be ready in February and the Company is expecting to have this equipment operational by April 2008. The addition of the ball mill and secondary crusher will significantly increase our throughput tonnage by more than 33%. As previously reported September processed tonnage through the mill averaged 199.5 tonnes per day. In October processed tonnage through the mill averaged 198.0 tonnes per day. Regular monthly shipments of gold and silver precipitate have surpassed the $1-million (U.S.) mark for the first time and continue to show increases in production value on a month-to-month basis. We anticipate in April, 2008 to be operating at a significant increase in daily throughput while at the same time feeding higher grade ore through the system with silver recoveries increasing from today's 40%-50% to approximately 85%-90%. Based on current spot market prices, implementing these upgrades simultaneously should increase our monthly cash flows significantly. 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.rochesterresourcesltd.com/s/ShareStructure.asp). We have identified 37 vein structures (http://www.ccnmatthews.com/ docs/ vein_structures.jpg) 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. -2- a significant player in Mexico. Rochester has a strong senior management team (http://www.rochesterresourcesltd.com/s/Management.asp) 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.
