VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 27, 2012) - Silvermex Resources Inc. ("Silvermex") (TSX:SLX) reports that preliminary metallurgical testing is being undertaken at its Peñasco Quemado project, located within the north-central portion of the Mexican state of Sonora, approximately 14.5 km west of the town of Tubutama, in the Magdalena-Tubutama mining district.

Samples of existing drill core were collected for metallurgical testing and sent to Hazen Research, Inc. in Golden, Colorado. Dependent on favorable results from Phase 1 laboratory testing, Phase 2 testing will be focused on definition of a flow sheet for milling. That proposed flow sheet will enable Preliminary Economic Assessment level cost estimates to be performed late in 2012 in order to determine expected capital and operating costs. Results from the first phase of laboratory testing are expected to be received in Q2 2012.

The near surface and oxidized nature of the mineralization suggest the deposit would have a low strip ratio and be amenable to low cost open pit mining methods. The project contains disseminated silver mineralization and minor amounts of gold and copper and manganese oxide within brecciated zones in a volcano sedimentary suite of rocks. In the past, very high grade fissure filling structures were exploited, at times producing over 2 kg/t Ag.

There is a current NI 43-101 compliant mineral resource estimate on the Peñasco Quemado property. This mineral resource estimate is based on a total of 3,442.61 m of core, rotary and reverse circulation drilling from 49 holes completed by Silvermex in 2005 and 2006 as well as by Cerro de Plata in the 1980s.

The current mineral resource estimate is as follows:

The resource estimate is compliant with the current CIM standards and meets the definition as required by NI 43-101 and is, therefore, reportable as a mineral resource by Silvermex. However, the reader should be cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability. The resource estimate was prepared on behalf of Silvermex by Micon International Limited and signed and dated March 9, 2007 and was posted on SEDAR on March 16, 2007.
