Grades of 137.8 g/t silver and 17.85% zinc over 1.55 meters returned from preliminary surface sampling at Lety Project in Durango Mexico

Silvermex Resources Ltd. has received assays as high as 137.8 g/t silver and 17.85% zinc over 1.55 meters from its preliminary surface channel sampling program at its Lety Project located in Durango, Mexico. The Lety property covers 5,130 hectares in the Northern portion of the state of Durango and is located near the historical mining districts of Magistral del Oro, Santa Maria del Oro and Guanacevi, in the Sierra Madre Occidental of Mexico. The Lety Project is 17 km north of the Pitarilla deposit of Silver Standard Resources Inc. on which a resource estimate in excess of 500 million ounces of silver has been reported.

The regional geology is represented by rhyolithic and andesitic rocks overlaying sedimentary cretaceous limestones and metamorphic rocks. The mineralization is controlled by a system of regional faults trending North West. The mineralized structures lie along the great Rodeo regional fault, known to host over 200 small bonanza grade mines that have operated intermittently since early Spanish Colonial times.

During the last quarter of 2007, Silvermex staff supervised a channel sampling program on several old workings and breccia zones on the Lety Project. Over 187 samples were collected during the program. Several anomalous zones were identified during the course of the sampling. The highlight of the program was the results received from the Verdosa zone. A table of the samples collected from the 7 meter wide Verdosa zone is found below:

Quality Control

As part of its QA/QC program the Company uses standard industry practice in its handling, preparation and processing of samples. This includes but is not limited to the segregation of duties and the use of blanks, standards and duplicate samples. The Company has contracted International Plasma Labs Ltd. (IPL), an ISO 9001:2000 accredited lab, to complete geochemical analysis and/or assay of the samples. Preparation of the samples occurs in IPL's facility in Mexico prior to secure shipment to Richmond, BC for analysis. In Richmond each sample is subjected to 30 Element ICP-ES (Inductively Coupled Plasma-Atomic Emission Spectrometer) analysis. Gold values above detection limits for ICP-ES are subjected to FA/AAS (Fire Assay and Atomic Absorption).
