ROCHESTER RESOURCES LTD Date: May 22, 2008 /s/ Nick DeMare ----------------------------- ------------------------------------- Nick DeMare, Chairman ROCHESTER RESOURCES LTD. #1305 - 1090 West Georgia Street, Vancouver, British Columbia, V6C 3V7 Phone: (604) 685-9316 Fax: (604) 683-1585 TSXV: RCT OTCBB: RCTFF Frankfurt: R5I - -------------------------------------------------------------------------------- NEWS RELEASE MAY 22, 2008 ROCHESTER TRENCHING DISCOVERS SIGNIFICANT VEIN AT FLORIDA NW VANCOUVER, CANADA - ROCHESTER RESOURCES LTD. (TSXV: RCT; OTCBB: RCTFF AND FSE: R5I) is pleased to announce the discovery of a new vein called Florida 4 at the Florida NW Mina Real Project in Nayarit, Mexico. The Florida 4 vein system is part of the main fracture system and has similar mineralogical characteristics as the Florida 3 vein system currently being mined at the Mina Real Project. The Company anticipates that the Florida 4 vein system will contribute significant mill feed to the 50% increase in mill production scheduled for Q3 2008. Highlight results from the trenching program includes: o Trench L1 Sample #29244 0.5 metres width averaging 24.5 G/T GOLD AND 97 G/T SILVER o Trench L1 Sample #29243 0.8 meters width averaging 7.05 G/T GOLD AND 221 G/T SILVER o Trench L4 Sample #29331 1.2 meters width averaging 7.04 G/T GOLD AND 96 G/T SILVER o Trench L5 Sample #29286 0.6 meters width averaging 6.06 G/T GOLD AND 81 G/T SILVER o Trench L10 Sample #21084 0.7 metres width averaging 1.6 G/T GOLD AND 761 G/T SILVER ** See Table 1 below for full results At Florida 4, 11 trenches have been developed exposing the vein system at surface for 2 kilometres. The trenches are located at different elevations ranging from 1000 meters above sea level to 1400 meters above sea level (figure 1). The vein system has a well defined quartz structure with widths on surface ranging from 0.3 metres to 1.5 metres. Sampling was completed at all 11 trench locations and 9 locations reported significant gold and silver values (Table 1). Results collected to date are similar to those received from the Florida 3 vein system at similar elevations. The Florida 4 vein system is parallel and approximately 450 metres west from the Florida 3 vein system. Assuming the favourable mining horizon of ore ranges from 1350 metres to 900 metres above sea level as confirmed at Florida 3, and an average vein width ranging from 0.5 metres to 1.5 metres over a 2 kilometre strike length the company anticipates that Florida 4 has the potential to supply significant additional tonnes of ore that will help ensure the upgrade in mill production this summer and contribute to further mill upgrades in 2009. The company is currently developing Florida 4 at different elevations with the primary focus being at the 1000 metre elevation. A drift within waste rock will be developed as an access to the parallel veins located in this area while concurrently, being used as a staging area for diamond drilling to help locate parallel vein systems at depth. A system of ramps and raises will also be developed for ventilation and for efficient extraction of ore, so the company can continue increasing production incrementally through 2008 and 2009. Dr. Parra states "The discovery and development of this new vein system at Florida NW is a milestone event for Rochester as we believe this will contribute substantially to our overall mine life at the Florida Mine and will help ensure that we will remain on schedule for the production increase this summer." -2- FIGURE 1 [GRAPHIC OMITTED][GRAPHIC OMITTED] Omitted graphic is Florida IV Long

ON BEHALF OF THE BOARD INVESTOR INFORMATION CONTACT: /s/ DR. ALFREDO PARRA Empire Communications Inc. - ---------------------- Tel: 604-484-0068 Dr. Alfredo Parra, Email: info@rochesterresourcesltd.com President and CEO Website: www.rochesterresourcesltd.com 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 We have identified 45 vein structures 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 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.
