Mexican Silver Mines Ltd. Reports Extension of Mantos in the First Phase of Drilling at the Iguana Mine

Mexican Silver Mines Ltd. (“Mexican Silver”) (TSXV: MSM; Frankfurt WKN: A0MSLE) has identified and tested significant mineralization from the Phase I drill program at the historic Iguana Mine. The Iguana Mine is a part of the 41 sq. km Ral (100% owned) property located in a tenement in the municipality of Lampazos, Nuevo Leon, see press release dated January 30th, 2008.

The purpose of the Phase I drill program was to determine if the manto that was previously mined extended past the end of the historical mine workings. Mexican Silver has successfully located and tested the continuity of this manto, also previously disclosed by geologic mapping and sampling in the nearby underground working of the Iguana Mine. Drill holes IG-07, IG-08 and IG-09 were sited 50-100 meters south-southeast of the end of the existing mine workings.

Mexican Silver is encouraged with the results from this first phase drilling, which consisted of three drill holes, as it confirmed the extension of the Iguana Mine manto.

The results from Phase I indicate that the manto type mineralization has a south-southeast continuity and the manto tends to thicken between IG-08 to IG-07 from 3.5 to 9 meters respectively. The manto is at a shallow depth of between 40 to 60 meters.

Mexican Silver will now carry out a Phase II drill program within an area of 180 meters by 250 meters. This program is currently underway. The second phase drilling is aimed at defining the tested mineralization for eventual conversion into indicated mineral resource.

The Iguana Project is a carbonate replacement deposit (CRD) with silver, lead and zinc occurring as mantos and as low-angled veins within vast skarn-altered zones. The mineralization is associated with an igneous rock complex characterized by stocks, dikes and sills of monzonite and monzodiorite composition that were intruded in a sequence of Cretaceous sedimentary rocks known as the Eagle Ford and Georgetown formation. The sulfides consist of galena, argentite, sphalerite, pyrite, with gangue minerals consisting of barite and quartz.

Previous reconnaissance geologic mapping/sampling indicated several mantos style mineralization outcroppings in an area that is 400 meters long and 200 meters wide. The mantos occur in stacks.

The significant mantos intercepted by the drill holes with the respective grades are as follows:

“The drilling at the Iguana Mine shows that the historical mining in the area did not mine out the available deposit,” stated Feisal Somji, President and CEO of Mexican Silver. “Much of the deposit still remains in place at both the Iguana and the recently acquired Voladora Mine, located 2.5 km from the Iguana Mine. This program has given Mexican Silver the first evidence of this. We are excited that the Iguana Mine is the first of many of our past producing mines where we can now start the process of defining and building a resource estimate.”

Mexican Silver will also pursue follow-up detailed mapping and sampling of other similar mineralized zones in the Iguana Area as well as in the immediate vicinity of the Voladora Mine, situated 2.3 km northwest of the Iguana Mine.

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 Iguana Mine, is the Corporation's nominated Qualified Person responsible for monitoring the supervision and quality control of the programs completed within the properties. Mr. Dynes has reviewed and verified the technical information contained in this news release.
