Drift Development Results at Tajos Cuates Confirm Extension of High Grade Gold/Silver Vein System

 Vancouver, Canada - Rochester Resources Ltd. (TSXV: RCT; OTCBB: RCTFF and Frankfurt: R5I): Dr. Alfredo Parra, President, is pleased to advise that the Company has completed a 95 metre drift at level 976 which interesected the extension of the Tajos Cuates vein system to the northwest of the existing drift development workings. This appears to be part of the same vein system that from surface sampling and old workings is believed to extend for a further 1.5 kilometers to the northwest. A vertical raise of 8 meters was completed at the intersection of the Tajos Cuates vein which confirmed the existence of two additional parallel high grade gold/silver veins. These veins pinch and swell and are between two and eight metres apart from one another. Both parallel veins are open vertically and open along strike.

Samples were collected from the two newly discovered veins at six intervals along the raise. Many of the intervals sampled produced very high grades. Examples include:
  • Sample 12353 assayed at 14.8 grams/ton of gold and 1.14 kilograms of silver;
  • Sample 12354 assayed at 30.6 grams of gold and 758 grams/ton of silver;
  • Sample 12363 assayed at 8.3 grams of gold and 833 grams/ton of silver.
The total average from this eight metre raise was 3.25 grams/ton of gold and 396 grams/ton of silver. (See Table 1 and Figure 1)

Surface work has also identified two new mineralized vein systems in the Tajos Cuates area, called Tomas and El Crudo. Preliminary surface channel sampling has returned widths of 2.10 metres grading 3.7 g/t gold and 137 g/t silver from Tomas, and 0.70 metres grading 4.9 g/t gold and 106 g/t silver from El Crudo.

"These results support our decision to embark on an aggressive exploration and development program at Tajos Cuates which we are hopeful will establish a more broadly based mining complex, with the capacity to increase gold and silver production well above existing levels." commented Dr. Alfredo Parra, President.

As is typical with epithermal vein systems, grades and width vary throughout the Tajos Cuates structure. The Tajos Cuates vein system is located 1 kilometre southwest of the Florida Mine site and is a primary target in the near term to outline additional potential ore sources for the existing milling operation. The vein system is a robust low sulphidation epithermal vein which has been traced on surface over 1.8 kilometres. Known workings and one historical drill intercept has defined a vertical horizon of minimally 200 metres. The mineralization is silver-rich compared to the Florida triple vein system -- a 1.70 metre wide sample collected by Victor Jaramillo P.Geo. from the Chalata Adit assayed 2.7 g/t gold and 1300 g/t silver. Three drill holes completed in 2006 provided confirmation that the mineralized vein structure continues to depth and established a base of the mineralized horizon near the 900 metre level. Drill hole No. 800-7-04 intersected 2.42 metres (estimated true width 1.5 metres) of mineralization which assayed 4.9 grams/tonne of gold and 310 grams/tonne of silver at the 915 metre elevation.

Recent work has extended road access to Tajos Cuates, and initial underground rehabilitation work is underway to allow exploration and bulk sampling of the vein system in detail. The multiple vein systems at Tajos Cuates are the primary target for expansion of our mining operations.

All assays quoted were carried out by the Durango, Mexico, branch of SGS Laboratories, a certified and independent laboratory. The exploration program is under the direction of Hector Chavez, a Mexican professional geologist who has extensive experience in Mexican epithermal deposits, and supervised by Dr. Alfredo Parra, who is a QP as defined in NI 43-101.
