San Anton Resource Corporation: Gold/Silver Heap Leach Study in Progress for Cerro del Gallo

TORONTO, ONTARIO--(Marketwire - Sept. 2, 2009) - San Anton Resource Corporation (TSX:SNN)

Update Highlights:

- 120Mt of Gold/silver dominant material identified at the Cerro del Gallo project, with large proportion potentially heap leachable

- Good gold and silver recoveries achieved from test work

- Study commenced based on an initial 4 million tonne per year, 8-10 year heap leach production project

- Experienced project team to progress development of Cerro del Gallo

San Anton Resource Corporation (TSX:SNN) is pleased to announce the following update on the Cerro del Gallo project, Mexico.

A strategic appraisal of the project has identified a potential pathway to commercialise the higher grade gold and silver domain of the existing, well understood gold/silver/copper resource.

The company has identified a significant amount of gold/silver-bearing weathered and oxide material - at very low strip ratio - within the existing resource at Cerro del Gallo, following a detailed review of all drill data, core and further modelling of the geological domains.

A study of the economic feasibility of a 4Mtpa low cost heap leach production approach has now commenced. Study time is anticipated as 2 months.

Project managers involved have previously successfully established multiple heap leach operations in the United States, Mexico and Australia. The processing approach is regarded within the mining industry as well understood, conventional technology, with good potential for rapid deployment and production start-up.

Mr John Cook, President and CEO of San Anton Resources Corporation stated:

"We are pleased with the outcomes of our activities of the past few months - already we have good indicative information of the costs attached to a heap leach gold/silver approach - as well as potential revenue scenarios from this 'at surface' and simple-to-process material. The study in progress will provide a cross-check to demonstrate the viability of this development pathway for Cerro del Gallo."

"Added to which, the depth of experience within our project team in Australia, Canada and Mexico in bringing these types of projects online on time and within budget, gives us considerable confidence in the immediate prospects for the Cerro del Gallo project."

Gold/silver dominant material

The previously reported total resources for Cerro del Gallo are shown in Table 1. Within this resource there is a well defined 'Gold Domain' where the mineralisation is higher in gold grade and lower in copper sulphide minerals.

Over the past several months a review of drill data and modeling of the various mineral and oxidation boundaries within this Gold Domain identified material in specific zones suitable for heap leach processing.

The estimated amounts of gold bearing material within the reported Gold Domain resources that may be suitable for heap leach processing are given in Table 3.

Metallurgical test work has been completed on samples selected to represent material from the weathered, oxidized and fresh rock. The test work consisted of intermittent bottle roll tests over a period of 30 days to simulate performance under heap leach conditions and to give an indication of the ultimate gold and silver extractions. The test work was completed at the SGS Lakefield-Oretest facility in Perth, Australia.

Two different crush sizes for the bottle roll tests were used, 6.35mm and 19mm. Crushing the material finer, improves gold recovery in the weathered material and this is more significant for the oxidized material. A summary of the recoveries from the bottle roll tests are shown below in Table 4.

The leach recoveries achieved from the intermittent bottle roll tests indicate that the weathered and oxidized material within the Gold Domain of the Cerro del Gallo resource is certainly amenable to heap leaching. Column tests will be performed on the weathered and oxidized material to gain further confirmation of the results from the bottle roll tests. Agitated leach tests will be performed on the 'fresh' rock material to confirm gold and silver recovery results from previous test work.

About San Anton Resource Corporation

San Anton Resource Corporation is an exploration and development company that is listed on the Toronto Stock Exchange and is totally focused on the mining friendly jurisdiction of Mexico. The Company's principal asset is a 64% interest in the San Anton Property (Goldcorp 36%), which hosts the near-surface Cerro del Gallo gold-silver-copper deposit. The Property is located in a historic gold-silver mining district and has only recently been subjected to modern exploration techniques. This work quickly identified several targets and has led to the delineation of a NI 43-101 Measured & Indicated Mineral Resource of 461 million tonnes grading 0.27g/t gold (3.9Moz), 11g/t silver (163Moz) and 0.11% copper (1.09Blb) and an Inferred Mineral Resource of 166 million tonnes grading 0.11g/t gold (0.6Moz), 7 g/t silver (39Moz) and 0.10% copper (0.36Blb). Within the overall deposit, there is a 'gold domain zone' containing Measured & Indicated Mineral Resource of 209 million tonnes grading 0.48g/t gold (3.2Moz) and 11g/t silver (71Moz) and within this zone, there is a relatively higher grade gold resource defined at surface. The deposit remains open in several directions.
