Mexican Silver Mines Ltd. Hires Key Exploration Manager & Purchases Second Drill Rig

CALGARY, ALBERTA--(Marketwire - Oct. 11, 2007) - Mexican Silver Mines Ltd. ("Mexican Silver") (TSX VENTURE:MSM)(FRANKFURT:MS2)(WKN:A0MSLE) is pleased to announce that Mr. Carlos Escalante has accepted the position of Exploration Manger for Mexican Silver Mines Ltd. Mr. Escalante is a highly qualified Mexican geologist who has over 12 years experience in the fields of mineral exploration and mine evaluation. He recently held the position of Senior Geologist in charge of exploration in northeastern Mexico for Servicio Geologico Mexicano (SGM). Mr. Escalante brings to the company many years of direct experience working on Carbonate Replacement Deposits in the area of Mexico where the company's projects are located. Mr. Escalante has joined the company on a full time basis and the company acknowledges the level of experience, expertise and local knowledge that he will bring to our efforts in advancing our projects to the development stage.

The company is also pleased to announce the purchase of a second Longyear 44 Drill Rig. This new drill is identical to the first company owned drill rig and is a Longyear 44 Truck mounted drill rig purchased directly from the Mexican Longyear dealer. The second rig, along with over 500 m of drill steel, has been ordered and paid for and is expected on site by October 19, 2007. The company has retained a second drill crew which has already been mobilized to Vallecillo where the current drilling is taking place. The second drill rig will be delivered to the Vallecillo project and will compliment the first rig for this phase of drilling. Drilling at Vallecillo is going well and the company expects to increase its drilling efforts in this area.

"The addition of the second drill rig is very exciting for us," stated Feisal Somji, President and CEO of Mexican Silver Mines. "It not only speeds up the productivity of our drilling, and therefore of our news flow over the upcoming months, but it also shows the level of confidence that the management team has in our current drilling progress to date. With backlogs at the assay labs, we feel it is prudent to quickly extract core from the ground and deliver it to the lab so that we can maintain our objectives in developing a compliant resource within one or more of our existing past producing mines."

Mr. William Dynes, P. Geol. is the Qualified Person, as defined in NI 43-101, who has reviewed and verified the scientific and technical mining disclosure contained in this new release.
