Rochester Resources Ltd. (TSX VENTURE: RCT)(OTCBB: RCTFF)(FRANKFURT: R5I) is pleased to announce that an updated technical report has been prepared on the Mina Real Property in Nayarit, Mexico dated Sept. 30, 2008 by Victor A. Jaramillo, M.Sc. (A), and P.Geo. of Discover Geological Consultants Inc. Mr. Jaramillo on his most recent visit to the Mina Real Project was able to review geological work completed to date, such as drill data, examine drill core, underground geological information, geochemical data and maps of the property.

Significant highlights from the report include:

A geological potential has been estimated for the Florida-4 vein system taking into consideration parameters that are discussed in the report. This potential is provided in ranges as required by NI 43-101 reporting standards.

For the lower end range equals 225m depth x 2,000m length x 0.50m wide x 2.5 s.g. equals 562,500 tonnes with grades of 4.0 g/t gold and 60 g/t silver

For the upper end range equals 450m depth x 2,000m length x 1.0m wide x 2.5 s.g. equals 2,250,000 tonnes with grades of 8 g/t gold and 100 g/t silver

The range provided includes the following assumptions:

1. A very well mineralized mining horizon that ranges from 1350m to 900m elevation;

2. A vein width ranging between 0.5m and 1.5m (we will use 1.0m for upper range);

3. A 2.0 kilometre strike length as defined from surface outcrop;

4. A specific gravity of 2.5

The above geological potential is for one vein only. The Mina Real Property comprises approximately 20 veins that have been identified to date (to view Figure 1 please click on: http://media3.marketwire.com/docs/rct1020b.jpg). The writer believes the geological potential to be considerable.

Cautionary statement: Investors are cautioned that the potential quantity indicated above is conceptual in nature. At this time, there has been insufficient exploration to define a mineral resource below the current inferred resources, and it is uncertain if further exploration will result in the discovery of these mineral resources.

Previous news that was released dated July 24, 2008 reported grades from surface trenching at Florida 4. The results indicate similar surface results to what was encountered on surface and above the zone of favourable mineralization at Florida 3. Some of the results previously reported from this trenching program include:

The author noted that at the Mina Real Project, the presence of high grade gold-silver quartz-adularia veins and stockwork veinlets in the country rocks bears many geological similarities to Sleeper, Nevada; McLaughlin, California; Hishikari, Japan and Golden Cross and Martha Hill, New Zealand, all of which were or are significant gold producers.

The author who is a QP as defined by NI 43-101, has read and approved the contents of this news release.

About Rochester Resources Ltd.:

Rochester s a junior gold/silver producer engaged in the production and the continued exploration and development of its Mina Real and Santa Fe Properties located in the State of Nayarit, Mexico. Nayarit is located in the Sierra Madre Occidental range, the most productive epithermal precious metal region in the world, which hosts the majority of Mexico's gold and silver deposits. The Company substantially completed the construction of a cyanidation processing plant at the end of December 2006. Initial milling operations commenced in January 2007 with the commissioning process being completed by May 31, 2007. The Company has, in a very compressed time frame, acquired, developed and brought into production a gold property in Mexico. The Company now has an operating mill which is generating cash flow from operations. The Company is also implementing an exploration and development program utilizing funds raised in the capital markets and cash flow from operations to define resources to support future mining and production.
