Latin American Minerals Commences Exploration on its Tendal Zinc-Copper-Lead-Silver Property, La Rioja, Argentina

TORONTO, ONTARIO--(Marketwire - June 4, 2007) - Latin American Minerals Inc. ("LAT")(TSX VENTURE:LAT) announces the start of a comprehensive exploration program on its wholly owned Tendal zinc-copper-lead-silver project covering 36,488ha in La Rioja Province, Argentina.

Preliminary reconnaissance geological mapping and sampling has further defined the surface extent of the massive sulphides visible on the Ikonos satellite image. The massive sulphides are stratabound and occur as individual lenses, which pinch and swell within a mineralized envelop up to 80m wide, which has been traced along strike for approximately 2.0km. The main massive sulphide lens/body has been traced continuously in outcrop along strike for 1.2km and is up to 20m wide, averaging 15m wide in the Central Zone. Thinner lenses occur within the mineralized envelop, parallel to the main lens and within the footwall and hanging wall rocks. These smaller lenses range from several cm to 6m wide. The northern limit of the massive sulphides is cut by a younger hydrothermal breccia. The southern extension of the zone remains open but typically the lenses are smaller and more poorly defined.

Dr. Waldo Perez, Sr. VP Exploration reports "...the massive sulphide lenses/bodies comprise massive and disseminated specularite, galena, sphalerite, pyrrhotite and chalcopyrite and are constrained by repetitive deposition of sulphides in a basin of metasediments and mafic rocks, now highly deformed..."

Chip channel sample taken by LAT across two typical individual lenses/bodies returned the following assays:

Trench Cu% Pb% Zn% Ag (gpt) Width (m)
T-1 0.6 7.12 3.66 28.8 13.1
including 0.07 10.68 6.28 30.0 5.0
T-2 1.26 12.48 5.20 76.0 5.0

Sixty-four (64) samples were collected as part of the sampling program, including samples taken of the massive sulfides and the wall rock, averaged 38.8gpt Ag, 1.28% Cu, 1.63% Pb and 1.98% Zn. For complete sampling details, analytical procedures and completed assay results please see LAT's press release dated March 28, 2007.

The following table summarizes the average grade of noteworthy Canadian VMS deposits/mines.

Mine/Property Cu% Pb% Zn% Ag (gpt) Reference
Brunswick 0.36 3.60 9.70 - Xstrata
Kidd Creek 2.90 0.25 5.70 75.0 Info-Mine
Matagami 0.32 - 5.00 - Macdonald

The tables show that the assay results from the Tendal Property exhibit a similar order of magnitude to the average grades reported at Brunswick, Kidd Creek and Matagami.

Mr. David Wahl, President and CEO reports "...the early assay results are very encouraging not only because of the grade but also because the mineralization occurs over typical mining widths." Mr. Wahl also cautions that "... further work is required to determine the resource potential of the property".

To define the base metal potential at Tendal, LAT has initiated a comprehensive Phase I exploration program consisting of the following:

i) Sampling. Diamond saw channel sampling of the larger lenses/bodies of massive sulfides and the wall rock along the mineralized envelop (2,000m by 80m) and systematic sampling of the basement extending outwards from the mineralized envelop. Estimated 2,000 samples;

ii) Geological and structural mapping. The massive sulfide envelop will be mapped at 1:2,000 and the entire property will be mapped at 1:10,000;

iii) Geophysics. Area Geofisica SA., a reputable geophysical contractor from Buenos Aires, has been engaged to carry out on a total of 25 line kilometers of a surface EM Survey and 3 line kilometers of a test dipole-dipole survey. The Company has also retained John Kieley, P.Geo. as senior geophysical consultant to design and supervise the survey. Mr. Kieley has over 30 years of experience in all aspects of applied exploration geophysics and most recently he was Chief Exploration Geophysicist, of Barrick Gold Corporation;

iv) Road and Platform Construction: A total of 19km of road improvement and 5km of road construction and platform construction will be completed in August-September; and

v) Diamond drilling (5,000m HQ) will commence upon completion and interpretation of the geophysical survey, mapping and rock channel sampling results. Drilling is expected to start in October.

The total cost of the Phase I Program is estimated to be US $1.6 million.

Environmental assessments reports have been completed and submitted to the Government for approval. Camp construction including erection of insulated tents and rehabilitation of an old mine building is currently underway on the Property.
