VANCOUVER, BRITISH COLUMBIA, Feb 15, 2012 (MARKETWIRE via COMTEX) — Silvermex Resources Inc. (“Silvermex”) reports fourth quarter production results from its La Guitarra mine, located in the Temascaltepec mining district in the State of Mexico. Silver production increased from the previous quarter to 134,106 ounces and gold production to 1,010 ounces.

Fourth Quarter Highlights:

        —  Silver production up 94% from Q4 2010.

        —  Gold production up 101% from Q4 2010.

        —  The mine processed 23,810 tonnes of ore averaging 331 tonnes per day

            (“tpd”), above the average daily rate of 320 tpd.

        —  Recoveries to concentrate averaged 89% in silver and 78.4% in gold.

As a result of the extensive revitalization programs completed throughout 2011, production rates increased steadily, exceeding internal targets and surpassing historic rates in the fourth quarter of the year. Of note, the month of November saw total tonnes of ore processed exceed historic records dating back to the year 2000, when the La Guitarra mine was operated by Luismin S.A. de C.V.

Head grades and metallurgical recoveries were lower in the fourth quarter due to milling of lower grade ore from development in the northwest zone and from milling of low grade material from surface mining in years past. The space occupied by the low grade material was needed for expansion of surface facilities and therefore processed during the quarter.

Duane Nelson, CEO of Silvermex commented, “We are very pleased with the progress we have made in 2011. We continue to advance the La Guitarra mine on schedule and on budget. The mill performed above its designed capacity exceeding our expectations. We are also very pleased with the performance of the mine and mill staff throughout the year. Our current development programs are now advancing in ore, increasing our reserve base and life of mine for 2012 and beyond.”

Capital cost information for the quarter will be provided in conjunction with the year-end financial results to be released in late March. Silvermex is currently working on finalizing development and exploration plans for 2012. These will be announced in the coming weeks along with exploration results from La Guitarra and production guidance for the year.
