ROCHESTER RESOURCES LTD Date: November 20, 2007 /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 NOVEMBER 20, 2007 ROCHESTER COMMENCES DRIFT DEVELOPMENT AND MOBILIZES DRILL AT THE SANTA FE PROJECT, CLAVELLINOS AREA VANCOUVER, CANADA - ROCHESTER RESOURCES LTD. (TSXV: RCT; OTCBB: RCTFF AND FRANKFURT: R5I): Dr. Alfredo Parra, President and CEO, is pleased to advise that 800 metres of drift development has commenced at the Clavellinos vein system and the drill rig has been mobilized. A 3000 metre diamond drill program is planned and will commence shortly on the Clavellinos area of the Santa Fe Project, Nayarit State, Mexico. The exploration and development program (see Figure 1) will test the extensive vein systems identified by previous surface sampling and mapping. Figure 1: **Note: Theoretical Geological Model - green lines indicate proposed drill hole locations; lighter red thatched expressions indicate breccia zones mapped from surface; darker red lines indicate veins. [GRAPHIC OMITTED][GRAPHIC OMITTED] Graphic is schematic drawing of the Santa Fe Area Scale: 1:1000 Please view at Company's website: www.rochesterresourcesltd.com -2- Work to date has defined three main vein systems at Clavellinos, all of which trend northwest and are sub-parallel with some cross veining. From west to east, these are the Jonas System, the Clavellinos System and the Tajitos System. The Jonas system is located 120 metres west of and parallel to the Clavellinos System, and the Tajitos System is located 220 metres east of and parallel to the Clavellinos System. The strike length traced at surface for Clavellinos has increased and is now greater than 5 kilometres, Jonas has a strike length of 2.7 kilometres and Tajitos has a strike length approximately 1 kilometre. The strike extensions of all three vein systems are vegetation covered, and may mask greater strike lengths. The Company has recently constructed approximately 8 kilometres of new road access to the central portion of the Clavellinos area. This work exposed at surface the aforementioned vein systems with a significant discovery of a 40 metre wide mineralized alteration zone at the Clavellinos System with three sub-parallel high grade epithermal veins emplaced within. Work to date at the Clavellinos area includes trenching, channel sampling, mapping, structural interpretation, and geological modeling. Channel and trench samples to date have returned the following results: - -------------------------------------------------------------------------------- AVERAGE AVERAGE WIDTH GOLD SILVER ELEVATION - -------------------------------------------------------------------------------- 8.80 metres 1.96 g/t 140.19 g/t 1490 metres - -------------------------------------------------------------------------------- 8.32 metres 1.76 g/t 115.27 g/t 1470 metres - -------------------------------------------------------------------------------- 5.58 metres 2.94 g/t 271.16 g/t 1460 metres - -------------------------------------------------------------------------------- 18.40 metres 0.09 g/t 80.32 g/t 1300 metres - -------------------------------------------------------------------------------- In addition, a significant feature of the vein systems at Clavellinos is the identification of gold and silver mineralization over a vertical extent significantly greater than what is found at the Company's adjacent Mina Real Project. This will be better defined by the phase 1 diamond drill program. The vein structures on the Santa Fe Project appear similar to those encountered at Mina Real where strong gold and silver grades have been reported from the Company's mining activities. Dr. Parra states "This is an exciting time for Rochester as the drill program will provide an initial test of the extent and strength of the Santa Fe project and whether the project warrants its own processing plant. With the operating Mina Real mill nearby we will be able to quickly capitalize on success in this drill program and move forward with a separate plant if required" ABOUT ROCHESTER RESOURCES LTD. Rochester represents a pure-play into 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 a majority of Mexico's large tonnage gold and silver deposits. Current production generates positive cash flow and helps fund our ongoing exploration and development while minimizing share dilution. To date, we have identified 36 vein structures on our two projects and currently we have embarked on an aggressive exploration program including a 7000m drill program and 2000m drift development program that will determine the next steps for mine development and production levels. -3- Rochester is well positioned to advance its projects and can very quickly become a major player in Mexico. Rochester has a strong senior management team based in Mexico, an experienced workforce in place, and the capital to implement the work programs to advance our exploration and development projects towards production. All assays quoted were carried out by the Durango, Mexico, facility of SGS Laboratories, a ISO certified and independent laboratory. The exploration program is under the direction of Hector Chavez, a Mexican professional geologist who has extensive experience in Mexican epithermal deposits, and supervised by Dr. Alfredo Parra, who is a QP as defined in NI 43-101.
