Mexican Silver Mines Ltd. Announces an Exploration Update on its Iguana Project

CALGARY, ALBERTA--(Marketwire - Jan. 30, 2008) - Mexican Silver Mines Ltd. ("Mexican Silver" or "MSM") (TSX VENTURE:MSM)(FRANKFURT:MS2) is pleased to provide an update on exploration activities at its Iguana project on the Ral Concession. Diamond drilling commenced on the project in the fourth quarter of 2007 with a total of 911 meters being drilled to date utilizing MSM's company owned truck mounted Longyear 44 rig. A total of seven holes are planned in this first phase drilling program at Iguana with three holes completed at this time. Hole IG-04 is currently being drilled at a depth of 200 meters. All assays from sampling of drill core are pending.

The Iguana project is located within MSM's Ral Concession which encompasses an area of 10,160 acres. High grade silver-lead-zinc mineralization is found as replacement mantos and skarns within contact zones of Tertiary granodiorites in contact with Cretaceous limestones. In some of the mine workings, high grade mineralization extends for distances over one hundred meters as a replacement of individual limestone horizons.

At Iguana, both surface and underground rock chip sampling, primarily in the area of the Guadalupe Mine, has returned indications of high grade zones providing MSM with silver assays in the kilogram per ton range. Project scale rock chip and soil sampling has been carried out on a grid covering the entire area of surface alteration which coincides well with the area of historic mining activities. From the mapping program, favorable intrusive/limestone contacts have been defined and trenched exposing potential target zones which are now being drilled.

A geologic interpretation of the lithologies encountered in this drilling indicates that both high angle intrusive dikes and conformable intrusive sills are present within the overall zone of surface alteration that defines the Iguana project. Clay, quartz, sericite and pyrite alteration is seen in a number of the intermediate intrusive phases present in the drill core. Additionally, galena and sphalerite has been observed in varying amounts in spatial relation to these intrusive phases and within the carbonate horizons.

Upon the completion of this first phase drilling program at Iguana, and depending on the distribution and intensity of alteration in the subsurface, consideration will be given to running a close spaced IP survey to further define potential targets.

All drill core samples were shipped to ALS Chemex Laboratory ("Chemex") for analyses. Chemex has an International Standard Organization rating of ISO 9001:2000 and is independent of Mexican Silver. The split drill core sample was crushed and a sub-sample (aliquot) split off, pulverized and screened through a 150 mesh screen. Analyses were performed using standard acid digestion and spectrographic techniques.

Mexican Silver follows a rigorous Quality Assurance/Quality Control program consisting of inserting standards and duplicates into the sample stream submitted to Chemex for analyses. Mr. William Dynes, P. Geol., the project supervisor of Mexican Silver's drilling program on the Vallecillo Property, is the Corporation's nominated Qualified Person responsible for monitoring the supervision and quality control of the programs completed within the its properties.
