Rochester Provides Status Report on Mining and Milling Operations

Rochester Provides Status Report on Mining and Milling Operations


The Board of Directors is pleased to provide this update on the mining and milling operations at its Mina Real Mine in the State of Nayarit, Mexico.

Mining Operations

Work is continuing at the Mina Real mine in the form of drift development and underground stoping activities. There are three contract mining crews on site. One crew is working on driving a drift through the intrusive to the NW of the current mining area in order to access what surface sampling indicates is a continuation of the vein structures for a kilometre or more to the NW. Two other mining crews are working on stoping activities and drift development.

The ramp development from level 1115 to the lower levels has now advanced a total length of 192 metres - 127 metres has been development within the vein and 65 metres has been developed in waste rock to allow sufficient room for switch ramp development. See attached figure 1 which shows the underground development described. (To view figure 1, please click the following link: http://www.ccnmatthews.com/docs/rct0330.pdf)

Samples have been taken along the ramp development within the vein and assays received from SGS Laboratories, an independent ISO 2000 laboratory. The attached Figure 2 shows all assay results received to date from 32 channel samples taken along 76 metres of this development. The independent assays indicate an average vein width of 1.4 metres with average grades of 22.75 grams of gold per tonne and 193 grams of silver per tonne. Dr. Alfredo Parra, PhD and Qualified Person, commented that "The strong structure, the values and the coefficients of gold and silver ("the silver/gold ratio") on the ramp development below Level 1115 at around 8, suggests that the current development is approaching the core of the gold-rich mineralization and that the ore-grade mineralization continues to depth. These results combined with our knowledge of other vein structures in the area, support my belief that the bottom of the mineralized horizon could extend to the 900 metre level. Ongoing mine development work continues to meet and, in certain respects, exceed our expectations."

Milling Operations

Mina Real Mexico commenced start-up activities in January 2007 with the first delivery of gold and silver production to the refinery taking place in early February. During the mill commissioning activities, it became evident that a number of processing upgrades needed to be implemented in order to achieve maximum recovery of gold and silver and to accommodate increased production levels later in the year. The pregnant solution pumping and piping systems were found to be undersized and required replacement. This equipment has been sourced and will arrive at the mill shortly. In addition, the ore being processed was found to be more resistant to size reduction than originally anticipated and, as a result, it was considered prudent to upgrade the pumping and grinding equipment. Replacement of solution pumps has been expedited and, although milling operations have been temporarily suspended to effect these modifications, normal operations are expected to resume in 7-10 days. Capacity improvements are also being implemented to the grinding mill section of the plant which will allow our mill production to approach our initial target of 200 tonnes/day with 80% grind passing 100 mesh and recovery of 90%+ for gold. These changes are also expected to set the stage for further increases in capacity as the year progresses.

Dr. Alfredo Parra, the company's President, has an extensive background in mining exploration and operations, including senior management level positions with major Mexican based corporations such as CIA Minera Penoles and Kennecott. 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. Its key operating personnel are highly skilled and credentialed Mexican citizens with the ability to identify and negotiate the acquisition of other advanced exploration and development properties in the region. Operating management has strong support from an active board of consulting directors with extensive experience in mining, milling and exploration.
