Rochester Reports High Grades on Drift Development at Florida

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 28, 2007) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I): Dr. Alfredo Parra, President and CEO, is pleased to advise that 77 metres of drift development has been completed at the Florida triple vein system at the 1115 metre lower ramp level. As a follow-up to the April 25, 2007 news release regarding the upper ramp results at the 1115 metre level, we are also reporting significant anomalous results from the lower ramp at the 1115 metre level. Grades for both gold and silver are continuing to reflect our geologic model that grade remains strong at depth. The independent assays over 77 metres of drift development reflect an average vein width of 1.29 metres and average grades of 11.36 g/t gold and 120 g/t silver including 25 metres averaging 20.5 g/t gold and 107 g/t silver from Panel 3 (refer to the attached section below). Panel 3 includes significantly stronger results with multiple samples greater than 35 g/t gold including sample #12542 at 48.78 g/t, sample # 12581 at 43.6 g/t, and sample #12549 at 35.9 g/t (to view all sample results and figure please click on the following link:

Dr. Parra states, "Ramp development towards the basement level continues to progress successfully at our Florida Mine development reflecting some of our strongest grades to date. We continue to stockpile our high grade ore and intend to start processing this ore early in the New Year. With the strong spot price for gold and silver, and our sales program initiative to not hedge but sell at the spot price, we anticipate that this ore should add significantly to our monthly sales figures in the coming months."

All assays quoted were carried out by the Durango, Mexico, facility of SGS Laboratories, an 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.

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 a 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 36 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.
