Rochester Discovers Multiple Veins at Two New Prospective Areas: Samples 2.8M of 4.28 G/T Gold and 1405 G/T Silver

 Vancouver, Canada - Rochester Resources Ltd. (TSXV: RCT; OTCBB: RCTFF and Frankfurt: R5I): Dr. Alfredo Parra , President, is pleased to report on two new prospective areas at the Santa Fe Project, in addition to the Clavellinos Area, where diamond drilling is currently in progress. The regional exploration program has identified two new prospective areas, the Samuel and San Jose Areas. A total of 10 new vein systems have been identified at the Samuel and San Jose Areas. At the Samuel Area 5 veins have been sampled and assayed. Highlight results from the five vein systems at the Samuel Area include:
  • Samuel Vein: 1.6 m @ 0.51 Au g/t and 956 Ag g/t;
  • Marquesote-Catarino Vein: 2.8 m @ 4.28 Au g/t and 1405 Ag g/t;
  • La Paloma Vein: 0.85 m @ 0.3 Au g/t and 348 Ag g/t;
  • El Zopilote Vein: 0.6 m @ 0.28 Au g/t and 1030 g/t;
  • Guajolote Vein: 1.60 m @ 208 Ag g/t.

The Samuel Area comprises at this early stage of exploration 5 epithermal veins and is located adjacent and to the east of the Clavellinos Area (see Figure 1 below). Four veins have been emplaced parallel to one another trending NW-SE and all, from west to east, within 500 metres of one another. The fifth vein trends nearly N-S and is located in the northeastern section of the area approximately 500 metres away from the nearest vein system, Marquesote-Catarino. All the vein systems at the Samuel area have identified historic workings, this being a good indicator for a mineralized vein system. Until the Company began a systematic and detailed exploration program at Santa Fe to assess its potential there had been no modern exploration techniques applied to this project.

A total of 1.7 kilometres of epithermal vein strike length traced from outcrops and historic mine workings has been identified at the Samuel area. The area where these veins are located is vegetated with very little outcrop. The Company is early in their exploration efforts and expects to significantly increase their understanding of the extent of these mineralized vein systems. The Company's view is that this area is highly prospective and is a high priority for exploration follow-up in the near term. A short description of the veins is as follows:

Vein System Strike Length Widths Description
La Paloma
Fig 2 below
100 metres 1.20 m Central: Outcrop restricted, hidden by cover-
historic mine with 1.2 metre wide quartz vein
Fig 3 below
600 metres 0.70m--3.0m Central: Trending 300 metres along vein historic stopes and adits occur; in addition, parallel and detachment veins are present; quartz veins & faulting material conforms with the stopes - variable widths ranging from 0.7 metres to 3.0 metres.
El Zopilote
Fig 4 below
150 metres 1.0m Outcrop restricted, hidden by cover - historic mine with 1.0 metre wide quartz vein.
Fig 5 below
550 metres 1.0m-1.5m North: restricted outcrops but an old stope (Catarino 5 Mine) occurs, quartz veining 1.0 metre to 1.5 m wide; Ag Values sampled 284 g/t and Au 2.6 g/t Central: Covered South: several Old Mines (Marquesote), quartz veining 1.0 metre to 1.2 metre wide; Ag Values sampled 184 g/t and Au 1.1 g/t

The second area identified is the San Jose Area at the Santa Fe Project (see figure 1 and 7). The San Jose Area comprises 5 vein systems and is identified as San Jose vein systems #1-5. The San Jose Area is currently a reconnaissance project where the company is following up on previous work completed by past companies. No assay results have been published to date. All the veins have been traced at surface with strike lengths close to one kilometer with several veins striking greater than one kilometer. There is more than five kilometers of strike length noted at the San Jose area. This area will be aggressively explored over the coming months with assay results to follow. The San Jose Area is located adjacent and to the west of the Clavellinos Area at the Santa Fe Project.

All assays quoted were carried out by the Durango, Mexico, facility of SGS Laboratories, an ISO 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.

About Rochester Resources Ltd.:

Rochester represents a pure-play in 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 properties in the Sierra Madre Occidental Range. This is the largest epithermal precious metal region in the world, hosting the 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 37 vein structures on our two Projects (Mina Real and Santa Fe) and recently embarked on an aggressive follow-up exploration program including a 7000m drill program and a 2000m drift development program that will determine the next steps for mine development and production levels. Little follow-up work has been completed to date on the vein structures identified across both Projects.

Rochester is well positioned to advance its Projects and can very quickly become a significant player in Mexico. Rochester has a strong senior management team based in Mexico, a workforce in place to advance its projects through to mine development, and strong financial backing to implement and advance our work programs.
