Underground Drilling Continues to Extend Mineralization at Silvermex's La Guitarra Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 14, 2012) - Silvermex Resources Inc. ("Silvermex") (TSX:SLX) announces underground drill results from its La Guitarra mine, located in the Temascaltepec Mining District in the State of Mexico. A total of 91 underground drill holes have been completed for a total of 7,636 m. This drilling completes the 7,500 m drill program proposed in 2011, which was designed to test the continuity of various structures underground throughout the La Guitarra Mine. Drilling is ongoing by two contractor rigs and two rigs owned by the mine.

Recent drilling continues to extend the limits of gold and silver mineralization in existing stopes and ore chutes, which will be mined in the immediate future. "As was reported in a news release on November 3, 2011, our underground program has been very successful in identifying the largest ore chute to date in the La Guitarra mine," commented Michael Callahan, Silvermex's President. "Our most recent drilling continues to extend this zone both laterally and vertically. This program has been very successful in extending the life of the La Guitarra mine and we will continue with an aggressive drill campaign into 2012."

The La Guitarra mine is divided into three sectors: the Northwest Zone, the Central Zone and the Southeast Zone. Drilling in the Northwest Zone is focused on delineation of mineralized shoots for future production, in up to four distinct ore shoots within the broad La Guitarra vein. Delineation drilling in the Northwest zone has identified mineralized structures within the broader La Guitarra vein structure, which will aid in guiding future mine development. The presence of high grade gold and silver mineralization in parallel structures to the La Guitarra Vein is highly encouraging as such zones have been very productive in the past. Follow-up drilling will investigate the full potential of these structures.

In the Southeast Zone, a total of 57 holes have been completed. Drilling has focused on extending the Southeast Zone down dip and defining the strike length and plunge of the ore shoot. Highlights of the results include hole LGS-10, which intercepted 2.0 m of 509.1 g/t Ag and 1.71 g/t Au, hole LGS-13, which intercepted 0.9 m of 586.3 g/t Ag and 0.14 g/t Au, hole LGS-16, which intercepted 1.1 m of 476.1 g/t Ag and 2.32 g/t Au, LGS-17 which intercepted 2.1 m of 406.2 g/t Ag and 1.09 g/t Au, and hole LGS-44, which intercepted 0.15 m of 1,154 g/t Ag and 8.9 g/t Au. All widths are true widths. As shown in the table below, widths and grades for the LGS series of holes in the Southeast zone are consistent.

Assays for 29 of the 91 holes are reported in the table below. Previous results were reported on September 28, 2011 and November 3, 2011 and can be viewed on the Company website www.silvermexresources.com. All significant drill intercepts (defined as any mineralization grading a minimum of 150 g/t Ag equivalent using factor of 1 gram Au = 56 gram Ag) are presented in the following table:

Sampling of the drill core was overseen by a Minera La Guitarra geologist who marked off the drill core at appropriate intervals based upon the geology and mineralization present. Sample intervals normally vary from 0.2 - 1.0 m in length. No sample exceeded 1.5 m in overall length. All core samples were sent to Inspectorate Labs sample preparation in Durango, Mexico. Assays for gold were done by 1 Assay Tonne Fire Assay AA Finish and 4 Acid ICP-AES for silver and other elements. Gold assays that exceed 5 g/t by AA are redone using a gravimetric finish. Silver assays in excess of 100 g/t are redone using Fire Assay Gravimetric. Four acid ICP analyses were conducted at the main laboratory of Inspectorate in Reno, Nevada, USA. The GMU series of drill holes were assayed at La Guitarra's own laboratory (Fire Assay Gravimetric Finish) with check assaying of pulps from intercepts with significant intercepts completed by Inspectorate. Certified standards, blanks, and duplicate samples were inserted in every batch of 20 samples sent to all laboratories.
