Rochester Provides Operations Update at Mina Real

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 2, 2009) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I) is pleased to announce that operations at the Mina Real Property continue to show steady improvements. In early January 2009 the mill resumed operations and since then the Company has continued to see improvements in both mining and milling operations.

A total of 6,814 tonnes was processed for the months January and February 2009. Production during this period was 560 ounces of gold and 17,289 ounces of silver. Subsequent to the quarter end, operations continued to show improvement. During the month of March, 4,105 tonnes were processed through the mill, an increase of 20% over February, with head grades of 2.3 g/t gold and 299.4 g/t silver. During the month of April, 5,063 tonnes were processed through the mill, a further increase of 23% over March. April head grades were 1.7 g/t gold and 304 g/t silver.

Concurrently the Company has been working on increasing the silver recovery rates. In April, 2009 the average recoveries for gold were 93.63% and 71.51% for silver, a substantial increase from previous months which were averaging 91.10% for gold and 54.51% for silver. This significant milestone from milling operations will help contribute in the future to reducing the Company's operating costs per ounce produced.

Development has continued mainly from the Tajos Cuates area, at three levels: Hundido, Chalata and Socavon. The Company is planning to have the majority of its mill feed come from the Tajos Cuates area over the coming months. In addition, the Company has developed over 630 metres of road access to the Macedo area with another 350 metres remaining to get to the first structure (Veta Rica). The Company will require further funding to fully implement its work plans. The Company is working on further financings to ensure the funds needed for the business plan are available.

Dr. Parra is currently the Company's in-house Qualified Person and QP Member of the Mining and Metallurgical Society of America with special expertise in Mining.
