ROCHESTER RESOURCES LTD Date: July 31, 2007 /s/ Nick DeMare ----------------------------- ------------------------------------- Nick DeMare, Chairman ROCHESTER RESOURCES LTD. 400 - 535 Howe Street, Vancouver, British Columbia, V6C 2Z4 Phone: (604) 484-6614 Fax: (604) 688-3348 TSXV: RCT OTCBB: RCTFF Frankfurt: R5I - -------------------------------------------------------------------------------- NEWS RELEASE JULY 31, 2007 MINA REAL PRODUCTION UPDATE VANCOUVER, CANADA - ROCHESTER RESOURCES LTD. (TSXV: RCT; OTCBB: RCTFF AND FRANKFURT: R5I): Rochester is pleased to announce that our regular weekly shipments of gold and silver precipitate recommenced in early June and since then having shown significant increases in production value on a month-to-month basis. Shipments to the refinery for the four-week period ending June 29, 2007 had an estimated value of US$425,000, increasing to an estimated value of $671,000 for the four-week period ended July 28, 2007. During July processed tonnage through the mill has averaged about 180 tonnes per day with throughput exceeding 200 tonnes per day on occasion. The throughput has been impacted by the normal start up process and power interruptions. Said Dr. Parra " We are in the rainy season, which poses certain challenges to our day to day operations. June production was particularly impacted due to down time associated with intermittent power outages being experienced from our primary supplier of electricity. A second power generator was put into operation in the last ten days which gives us the power capacity to operate when there is disruption in service from the main grid." Further improvements are being implemented to attain more accurate and continuous reconciliation of the throughput tonnage, production, and deliveries to the refinery. Lower grade material is currently being processed as mill feed while the milling process is stabilized and recovery rates maximized. For the month of July the head grades averaged approximately 7 grams per tonne gold and 140 grams per tonne silver. Current recovery rate for gold is surpassing 90%. We remain positive about the prospects for significant increases in throughput tonnage and gold and silver production from current levels. We have not changed our expectations of achieving commercial production at the 200-250 tonnes/day level during the second half of 2007 and then moving to higher levels of production as mining activity dictates An updated report on exploration results is pending from our Mina Real and Santa Fe properties. 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. Rochester represents a pure-play into the exploration and development of gold and silver properties located in Mexico. The Mina Real Mine could certainly be considered a "high-grade" gold/silver deposit with grades reported in 2007 from mine development averaging 12 grams/tonne gold and 200 grams/tonne silver over 775 metres of drift development. With the completion of the Mina Real mill, management believes that its Mina Real and Santa Fe properties have the potential to produce a long-term revenue stream.
