Latin American Minerals Adds a Second Drill on Its Tendal VMS Project La Rioja, Argentina

TORONTO, ONTARIO--(Marketwire - April 22, 2008) - Latin American Minerals Inc. (TSX VENTURE:LAT) announces that based on encouraging results it has added a second drill to is Tendal massive sulphide (Zn-Cu-Pb-Ag) project and commences a gravity survey at its La Rioja, Argentina. The second drill rig arrived on site today and will accelerate and support the 5,000m diamond drill program currently underway on the property.

Mr. David Wahl, President and CEO reports that "...the decision to add a second drill at Tendal reflects LAT's confidence in the project and the need to compress the drilling to allow for the possible extension of the current 5.000m drill contract...".

Additionally, LAT has engaged Quantec Geoscience of Mendoza to carry out a gravity survey designed to detail and extend the gravity anomaly identified during the reconnaissance gravity studies completed on the property last year. The 300m long gravity anomaly is located approximately 250m west and parallel to the Verdiona massive sulphide trend.

Dr. Waldo Perez, Senior VP Exploration reports that "...the results of this survey will provide vectors for drill-hole targeting in the area geologically inferred to host the displaced and down dip extension of the Verdiona massive sulphides...".

For further information reference www.latinamericanminerals.com and follow the links to Tendal and the block diagrams depicting the conceptual structural evolution of the Tendal Verdiona Mine zone.

Preliminary results of the gravity survey are expected by the end of May and along the drill results of the current Phase I program will provide the basis for an independent 43-101 report on the Tendal project and support for our Phase II drilling program commencing in Q-4, 2008.

The Tendal project is 100% owned by LAT and consists of six large mining concessions in two blocks covering 36,434 hectares. Included in the project area, are several small historic mines, comprising less than 1% of the total project area. Five of the historic mines have been acquired by LAT including the Yegua Pircada lead prospect covering 18ha, the Verdiona zinc-copper prospect covering 6ha, the Estrella Primera copper prospect covering 6ha and Estrella Alta copper prospect covering 6ha. Teck Cominco Limited has also been acquiring exploration concessions and historic mines in the area and owns five small historic mines covering 114ha within LAT's exploration concessions. Please refer to LAT's website (www.latinamericanminerals.com) for the location of LAT's mining concessions and the historic mines.

The diamond drill program is designed to test the massive sulphide mineralization exposed on surface on the Verdiona, Yegua Pircada, Las Catitas and El Alto Zones, as shown on the Company web site.

The Verdiona massive sulphides are stratabound and confined to a horizon, which can be traced on surface for almost 2km and is up to 80m true width. The mineralization occurs as numerous individual stacked lenses of massive sulphides, which strike northerly and dip westerly at 40 degrees and range from 1 to 35m thick (true width). The mineralization is variably oxidized on surface comprising oxides of copper (chalcocite and malachite) and lead along with sphalerite and specularite. Diamond saw channel sampling has been completed across the entire length of the Verdiona massive sulphide trend. The significant assay results include:

The Yegua Pircada massive sulphide discovery is located 3.6km west of the Verdiona Zone. The sulphides are stratabound and occur within limestone unit that is 40m wide and trends N-S, parallel to the Verdiona Zone. Massive sulfide mineralization has been traced on surface for over 700m in two main mineralized zones located at the hanging wall and footwall of the limestone unit. Each mineralized zone is between 8-12m wide and is comprised of several lenses up to a meter wide and many smaller parallel lenses. Diamond saw channel sampling has been completed across the entire length of the Yegua Pircada massive sulphide trend. The significant assay results include:

Las Catitas massive sulphide discovery is located 400m south of the Verdiona Zone. Las Catitas is a complex mineralized zone approximately 300m wide. Mineralization is found in lenses similar to the ones exposed on the Verdiona Zone, in veins and disseminated in the host rock. Massive sulphide lenses are up to 3m wide and have been traced in outcrop for approximately 50m. Chip channel sampling returned 3.33% Cu, 0.37% Zn and 25gpt Ag over 3m. Host rock (sandstone) adjacent to the mineralized lenses/veins contains disseminated sulphides. Trenches 39 and 40 in the following table shows the extension of disseminated mineralization in the wall rock:

El Alto massive massive sulphide discovery is located 700m west of the Verdiona Zone and consists of five parallel E-W vein breccias between 0.4 and 1m wide. The veins can be traced in outcrop for approximately 50m, at which point, the vein-zone is covered by overburden. Selected grab samples returned to 9% Cu and 0.2% Zn.

Dr. Perez is the Company's internal "Qualified Person" under the requirements of National Instrument 43-101 and is responsible this press release.

LAT is a mineral exploration company focused on the acquisition and development of base and precious metals projects in under-explored but highly prospective countries of Latin America.

Sampling and Analytical Protocols: Sampling and analytical protocols were implemented and supervised by or under the direction of Dr. Waldo Perez, the Company's internal Qualified Person as defined by National Instrument 43-101. All of the lithogeochemical samples were collected by geologists taking into account the nature of the material being sampled and with due respect to geologic contacts. The individual sample interval varied depending on the location but typically ranged from 0.5 to 5.0 metres. Each individual sample weighted between 2 to 5 kilograms and was collected in a plastic bag, tagged with a pre-numbered ticket and tightly closed with plastic tape. The samples were stored in a secured location at the base camp and were transported by Company professional to Alex Stewart Assayers Argentina S.A. ("ASAA") laboratories in Mendoza (Argentina). ASAA is an ISO 9001-certified laboratory with headquarters in England. The samples were crushed, dried, split and grinded to #200 mesh. A total of 200 grams of sample have been separated for analysis. All samples were assayed for 39 elements by ICP. The samples were dissolved in Aqua Regia at 120degreesC and read in ICP-OES. The samples that were above the upper detection limit for Cu, Pb and Zn (1%) for the technique were reanalyzed by dissolving in Aqua Regia again using a larger volume of solution to raise the upper detection limit to 30% for Cu, Pb and Zn. Silver above 200 ppm was re-run by Fire Assay with gravimetric finish. Accuracy and precison of results is tested through the systematic inclusion of certified reference standards, blanks and duplicates.
