COMPANY DATA

INTRODUCTION

Rochester Resources Ltd. is a junior gold and silver producer that commenced milling operations at its high-grade gold and silver Mina Real mine in Nayarit, Mexico in January 2007. Nayarit is located in the Sierra Madre Occidental range - the largest epithermal precious metal region in the world - which hosts the majority of Mexico's gold and silver deposits. In March of 2007 Rochester entered into an agreement to acquire a 70% interest in the promising 3,800 hectare Santa Fe gold-silver property located immediately east of the Mina Real property.

PROJECT IN HAND

(1) Mina Real Property, Mexico

In December 2006 Rochester Resources Ltd acquired the remaining 49% interest, and now holds 100% interest in the Mina Real gold and silver property comprising of 3,400 hectares of exploration and mining concessions located east of the capital city of Tepic, in the state of Nayarit, Mexico. On January 30, 2007, Rochester added to its land position by staking an additional 3,981 hectares adjacent to the 3,400 hectares.

Highlights include:

• 100% ownership of the high grade Mina Real Mine property

• Commenced high-grade gold/silver milling operations in January 2007

• The Mina Real Mine recently produced average grades of 12.1 g/t of gold and 209 g/t of silver on channel samples over 775 metres of development mining with higher gold grades subsequently reported in ramping to lower levels.

• Potential for up to US$24 million in gross smelter revenues in first full year once plant reaches targeted recovery rates at 250 tpd capacity level

• Experienced and highly qualified Mexican exploration, mining and milling management team in place

• Scaleable mill design to provide short time frame and minimum cost to increase mill capacity to 300 tonnes per day level

• Identified over 10 km of gold/silver vein systems.

The Mina Real mill is still in the start-up phase and has just undergone modifications to allow mill production to approach 250 tonnes/day and recovery of over 90% for gold. The material produced from the ongoing mine development has been stockpiled as mill feed. Mill recovery rates for silver are expected to reach close to the same levels as gold upon installation of a process to deal with the varying levels of manganese. The modular design of the mill should allow for the planned increase in capacity to be quickly implemented at a minimal cost.

(2) Santa Fe Property, Mexico

On March 12, 2007 Rochester entered into an agreement to acquire a 70% interest in the Santa Fe gold-silver property located immediately east of its high-grade Mina Real Property in the State of Nayarit, Mexico. The property covers approximately 3,800 hectares, and previous work has identified ten zones of epithermal veining and mineralization on the property. This brings Rochester's total land package to 11,181 hectares.

Highlights include:

• 70% interest in the promising 3,800 hectare Santa Fe gold-silver property

• Ten (10) vein structures identified to date

• Mineralization occurs over an elevation of up to 700 metres

• Structures range from high-level discrete veins to broad zones of alteration containing multiple veins

• Surface grades identified are comparable to Mina Real vein structures

• Significant mineralized structures identified in close trucking proximity to the Mina Real Mill

• The Santa Fe property is within trucking distance of the Company's Mina Real Mill and has the potential to provide additional mill feed to support a material increase in capacity at the Mina Real Mill or possibly support the development of a second mill in the area by late 2008.

NEWS UPDATE

On July 31, 2007, Rochester Resources Ltd. provided Mina Real mill production update. Its regular weekly shipments of gold and silver precipitate recommenced in early June and since then have 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 US$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 Company remains positive about the prospects for significant increases in throughput tonnage and gold and silver production from current levels. The Company has not changed expectations of achieving commercial production at the 200 to 250 tonne per day level during the second half of 2007 and then moving to higher levels of production as mining activity dictates.

An update report on exploration results is pending from the Mina Real and Santa Fe properties.

On June 12, 2007, Rochester Resources Ltd. announced that it has granted stock options to directors of the Company to purchase up to 100,000 shares of the Company, at a price of $1.65 per share, for three years.

On June 8, 2007, Rochester Resources Ltd. reviewed its Mina Real mine in Mexico.

"The Mina Real plant has been operational for 11 days since resumption of milling operations and is performing satisfactorily," stated Dr. Alfredo Parra, President. "In spite of the global challenges involved in assembling equipment, materials and competent skilled labour, the Mina Real mill was put into production after only 12 months from receipt of permits." An update follows.

Operating results during the March 2007, period of the test-production phase indicated that it would be prudent to modify the grinding circuit to obtain throughout of about 250 tonnes per day and the gold/silver final recovery section to ensure planned recovery. Accordingly, the following major modifications planned for late 2007 have been brought forward:

• Installation of larger-capacity solution pumps and a third grinding mill;

• The installation of a cyanide destruction circuit to treat mill effluent.
