Latin American Minerals Reports Drilling has Started on its Tendal Massive Sulphide Project, Argentina

TORONTO, ONTARIO--(Marketwire - Feb. 19, 2008) - Latin American Minerals Inc. (TSX VENTURE:LAT) announces the start of a 5,000m diamond drill program on its Tendal Copper-Lead-Zinc-Silver project in La Rioja, Argentina. The drilling is being carried out by Boart Longyear formerly Patagonia Drill.

Over the past 30 days work focused on rebuilding several sections of the access road washed out by abnormally heavy rains high in the Andes. The road reconstruction has been completed and drilling has started on the first of eight (8) holes to test the Verdiona Massive Sulphide Zone. Two holes will be drilled from each of four (4) drill platforms constructed earlier this year at 50m intervals along strike of the massive sulphides exposed on surface.

"We are very excited that the drilling is turning at Tendal. Over the past six months, numerous challenges have been managed extremely well by LAT's team on the ground and we look forward to having drill core at the PDAC in March. The sulphide minerals and assay results are similar to those report at other VMS deposits such as Brunswick reporting a run of mine grade of 3.6% Zn, 0.36% Pb and 9.7gpt Ag, and Matagami 5.0% Zn and 0.32% Pb," reports David Wahl, President and CEO.

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 50 degrees and range from 1 to 35m thick (true width). The mineralization is oxidized on surface but locally the artisan workings have exposed the primary sulphide minerals to be sphalerite (zinc), chalcopyrite (copper) and galena (lead with silver) associated with pyrrhotite and specularite. Diamond saw channel sampling across typical lenses returned the following:

Channel Sample Interval (m) Zn (%) Cu (%) Pb (%) Ag (gpt)
C-3 5.0 4.64 0.04 1.87 23.20
C-4 12.0 6.43 1.04 1.16 111.76
including 6.0 8.67 0.70 2.24 16.00
C-5 27.0 3.70 0.11 2.95 13.69
including 7.5 5.69 0.34 1.75 34.40
including 10.0 3.01 0.02 4.63 10.85

Drilling is also planned and platforms have been complete to test the Yegua Pircada, Las Catitas and El Alto massive sulphide zones.

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. Grab samples of the mineralized lenses returned 1.2% Zn and 0.6% Cu.

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 samples returned 3.33% Cu, 0.37% Zn and 25gpt Ag over 3m. Host rock (sandstone) adjacent to the mineralized lenses/veins contains disseminated sulphides. Chip channel samples returned 2.24% Cu, 1.0% Zn, 0.13% Pb and 157gpt Ag over 2m.

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.

The Tendal project, which is predominantly owned by LAT (please refer to LAT's website ( for the location of the historic mines and exploration concessions at Tendal), comprises six large 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 Yegua Pircada (18 hectares, Pb), Verdiona (6 hectares, Cu), Estrella Primera (6 hectares, Cu) and Estrella Alta (6 hectares, Cu). Teck Cominco Limited has also been acquiring exploration concessions and historic mines in the area and now owns five small historic mines within LAT's exploration concessions.

Investor Question:

Mr. M from Edmonton asks: "... In previous press releases you have said the assay results are significant; what would be the comparable gold grade of the mineralization at Tendal...".

CEO Replies: "I have received many phone calls on this subject. Most investors feel comfortable with reported gold grades or contained ounces, but don't have the same comfort level with base metals (zinc, copper, lead and associated silver) values. Mathematically, if you have the average grade, metal recovery and metal prices you can generate a comparable number; however, I would call it an order of magnitude number at best. We do not have a resource nor do we have any metallurgical data. Additionally, Exchange Policy 3F/5.3g does not allow me to report gross values; however, it can be pointed out that the average grade of mineralization cut in channel samples C-3, C-4 and C-5 reported in this release is 4.25% Zn, 0.35% Cu, 2.34% Pb and 41.56gpt Ag. These grade equate to 85lbs of zinc per ton; 7lbs of copper per ton, 46.8lbs of lead per ton and 1.21opt silver per ton. Kitco Metal prices are currently Zn $1.10/lb, Cu $3.70/lb, Pb $1.43/lb and Ag $17.00/oz. CAUTION: Please take my answer as an honest attempt to answer an excellent question, but please treat the comparable as an "order of magnitude" number only and there is no assurance that the comparable is real or attainable."

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: 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 5.0 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 gold, multi-elements by ICP and Hg by cold vapor. Gold was done by Fire Assay and AAS using a 50 gram sample. For the multi-elements the samples were dissolved in Aqua Regia at 120ºC 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.
