Latin American Minerals Inc. Announces High Grade Assay Result and Increased Land Position at Its Tendal Zinc-Copper-Lead-Silver Property, La Rioja, Argentina

TORONTO, ONTARIO--(CCNMatthews - March 28, 2007) - Latin American Minerals Inc. (TSX VENTURE:LAT) (the "Company") is pleased to announce the results of a sampling program carried out on the massive sulphide zone discovered on its Tendal Zinc-Copper-Lead-Silver property (the "Property") and that it has increased its land position from 24,296 to 36,488 ha in the view of current positive results.

Preliminary reconnaissance geological mapping and sampling has further defined the surface extent of massive sulfides ("VMS"). The VMS occur as stacked lenses within a folded sequence of sediments and volcanic rocks, which can be variably traced along strike for almost 2km. The northern limit of the VMS is cut by a younger hydrothermal breccia. The southern extension of the zone remains open but typically, the individual lenses are smaller and more poorly defined.

The VMS lenses outcrop within an 80m wide mineralized zone containing up to 11 different layers of VMS constrained by either structural repetition or by repetitive deposition of VMS across the sedimentary sequence. The individual lenses are up to 15m thick and have been traced along strike for several hundred of meters. The variably mineralized material (sediments?) between the layers of VMS ranges from centimeters to several meters in width.

The following table summarizes the typical chip channel sample assay results across representative stacked massive sulphide lenses. Please visit www.latinamericanminerals.com for complete assay results.



Sample length (m) Silver (gpt) Copper (%) Lead (%) Zinc (%)

13.1 30.0 0.60 7.12 3.66
(including 5.0m) 28.8 0.07 10.68 6.28

5.0 76.3 1.26 12.48 5.20

5.8 42.5 1.05 5.63 1.25

2.5 99.0 2.50 3.58 3.18

1.7 288.0 2.67 3.64 0.22


The wall rock in contact to the VMS was also sampled. The average of the 22 samples from the wall rock yielded 24.23 gpt Ag, 0.61 % Cu, 1.91 % Pb and 1.15 % Zn, confirming that the wall rock of the VMS is also mineralized.

The average grade of all 64 samples collected (including VMS and wall rock) is 38.8 gpt Ag, 1.28 % Cu, 1.63 % Pb and 1.98 % Zn.

Grab samples in quartz-oxide veins in the periphery of the VMS area returned silver assays of up to 1.2 Kg Ag per tonne.

Dr Waldo Perez P.Geo., Sr. Vice President Exploration, stated that "... the initial results are very significant; however, there is much to learn about the geology of the Property. The geological sequence was originally thought to be Ordovician, but it is now clear that it is an older unit (Precambrian?), which further defines the model as being analogous to other significant VMS deposits in the world such as Bathurst and Noranda. The exploration potential of the Tendal project has increased significantly...".

Mr. Wahl, P.Eng., P.Geo and CEO of the Company reported that "...the current exploration program at Tendal is being elevated to a higher priority, which will see more funds allocated to drilling this new discovery. Currently, the Company is completing government compliance reporting to facilitate rehabilitation of the access road to the Property, which should be initiated in the next few months clearing the way for a very aggressive exploration program..."

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 intervals varied depending on the location but typically ranged from 0.5 to 5.0m. A total of 100 samples were collected including 64 in the area of the VMS and 36 in the surrounding ground. Each individual sample weighted between 2 to 5 kg 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 gold, multi-elements by ICP and Hg by cold vapor. Gold was done by Fire Assay and AAS using 50 gm sample. For the multi-elements the samples were dissolved in Aqua Regia at 120 degrees C 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 of results is tested through the systematic inclusion of certified reference standards.
