Silvermex Resources Ltd.: San Marcial Technical Report Filed

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 21, 2007) - Silvermex Resources Ltd. ("Silvermex") (TSX VENTURE:SMR) is pleased to report that it has filed on Sedar, a report titled NI 43-101 Technical Report for the San Marcial Property, La Rastra Mining District, Sinaloa, Mexico (the "Report") authored by Mr. William Lewis, B. Sc., P.Geo of Micon International Inc. of Toronto and Mr. N. Eric Fier, C.P.G., P. Eng. Mr. Fier had previously prepared a resource estimate on the optioned property in 2002 for a previous operator.

Pursuant to current CIM definitions for Mineral Resources the optioned property hosts an Inferred Mineral Resource of 14.26 million ounces of silver, 33 million lbs of zinc and 16 million lbs of lead (2.31 million tonnes grading 191.79 g/t silver, 0.66% zinc and 0.32% lead).

Based on work to date, a number of silver targets that may be amenable to bulk mining techniques have been identified. The most advanced of these targets is the San Marcial SE and NW zone which extends for 450 metres along strike and is open in both directions and at depth.

The best values to date are returned from a 2001 drill program completed by previous operators. Diamond drill holes SM-4 and SM-5 from the San Marcial SE zone returned the following intercepts:

Silver Silver
Drill Interval Grade Interval Grade
Hole From To (in metres) (g/tonne) (in feet) (oz/ton)
SM-4 3.0 69.0 66.0 205.9 216.5 6.0
incl. 6.0 21.0 15.0 637.0 49.2 18.6
SM-5 1.4 36.0 34.6 205.3 113.5 6.0
incl. 1.4 9.0 7.6 415.1 24.9 12.1
incl. 15.0 21.0 6.0 342.7 19.7 10.0

The Conclusion section of the Report states:

"San a project with known silver mineralization and associated mineralization occurring in a series of two parallel veins, which have been the subject of a number of historical working and drill holes. The two parallel veins have been the subject of a CIM compliant mineral resource estimate which was originally conducted in 2002 and has been reviewed and found to be still valid in 2007.

Further exploration work will be needed to determine whether or not the existing inferred mineral resource can be upgraded and expanded."

Technical staff of Silvermex is of the view that the optioned property has significant exploration potential and is currently reviewing existing data in order to prepare for an exploration program which will include drilling. The exploration program is scheduled to commence in the first quarter of 2008.
