Rochester Announces Mill Production And Silver Recovery Update For Its Mina Real Mill
|
| | Vancouver, Canada - Rochester Resources Ltd. (TSXV: RCT; OTCBB: RCTFF and Frankfurt: R5I): Rochester is pleased to announce a mill production update for September and October, 2007. Our regular monthly shipments of gold and silver precipitate have surpassed the $1 million mark for the first time and continue to show significant increases in production value on a month-to-month basis. Shipments to the refinery for the four-week period ending September 30, 2007 had an estimated value of US$858,612, increasing to an estimated value of US$1,031,305 for the four-week period ended October 31, 2007.

During September processed tonnage through the mill averaged 199.5 tonnes per day. In October processed tonnage through the mill averaged 198.0 tonnes per day. The throughput has been equalized in the past few months with normal start up procedures becoming further streamlined. Said Dr. Alfredo Parra, "We are making excellent strides in stabilizing our mill production. Our operation continues to be more consistent and our plans to increase our production in the not so distant future remain intact." Lower grade material continues to be processed as mill feed while the recovery rates are maximized. For head grades and recovery rates please refer to table 1.
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 November and December, 2007 and then moving to higher levels of production in the New Year as mining activity dictates.
Update on silver recovery rates:
Joseph Keane, consulting director of the Company, and director of METCON Research Inc. of Tuscon, Arizona, has recently completed a test for silver recovery of Rochester's Florida triple vein system. The outcome was a success recording 91% recovery rates using a SO2 pre-wash followed by putting the ore back through the circuit. The Company will be following up this success at METCON Research Inc. with four additional samples representing four different types of ore found Project-wide.
We expect by early December to have a successful outcome and a go ahead to implement the new circuit and procedure into the mill production with expected silver recovery rates greater than 90%. The implementation process is expected to be complete in time for processing the silver-rich ore at Tajos Cuates early Q2 2008.

About Rochester Resources Ltd.
Rochester represents a pure-play into 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 high grade gold-silver 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 three projects and embarked on an aggressive exploration program including a 7000m drill program and 2000m drift development program that will determine the next steps for mine development and production levels. Rochester is well positioned to advance its projects and can very quickly become a major player in Mexico. It has a strong senior management team based in Mexico, the workforce in place to advance its projects, and the capital to implement the work programs to advance our exploration and development projects towards production.
