Latin American Minerals Intersects Gold Mineralization in All Drill Holes at Tacuru on the Paso Yobai Gold Project, Tests New High Grade Zones: 107 gpt Over 2.7m & 94.6 gpt Over 2.1m True Width
TORONTO, ONTARIO -- (Marketwire) -- 07/24/12 -- Latin American Minerals Inc. (TSX VENTURE: LAT)(OTCQX: LATNF) (the "Company") announces results for the Tacuru target, part of the X-Mile Gold Trend located within the Company's 100% owned exploration concession at Paso Yobai, Paraguay. Twelve holes totalling 1712 metres have been drilled at the Tacuru target to date, all of which intersected gold mineralization. Highlights from the most recent drilling include:
-- DDH-BT-08:
-- true width 22.0 m with 4.20 gpt gold including 5.69 m with 11.24
gpt, beginning at surface;
-- true width 2.13 m with 94.6 gpt gold including 0.7 m with 271.2 gpt
at 34.6 m vertical depth; and
-- true width 2.7 m with 107.7 gpt gold including 0.47 m with 611.07
gpt at 83.3 m vertical depth.
Results from the first five drill holes were announced in the Company's press release of March 6th, 2012. The final results from these five drill holes are being presented following the receipt of new fire screen assay duplicate analyses. Some of the notable results include:
-- DDH-BT-02: true width 20.88 m with 4.09 gpt gold beginning at surface,
including 3.77 m with 16.19 gpt gold at 4.9 m vertical depth which
includes 1.06 m with 25.6 gpt at 7.61 m vertical depth;
-- DDH-BT-04: true width 13.27 m with 3.35 gpt gold, including 2.95 m with
5.27 gpt beginning at surface and 0.45m with 10.4 gpt at 37.68 m
vertical depth;
-- DDH-BT-05: true width 8.93 m with 2.97 gpt gold, including 3.0 m with
6.48 gpt beginning at surface and 5.16 m with 1.9 gpt at 39.07 m
vertical depth.
Tacuru is an extensive target area with a prominent surface gold soil anomaly of 700 metres diameter, initially explored with a reconnaissance trench that showed 3.8 gpt gold over 30.55 metres (LAT press release Dec. 15, 2011). The 12 drill holes comprising Tacuru's drill program to date were inclined -55 degrees and penetrated to a vertical depth of approximately 120 metres. The drill results have tentatively defined four types of gold mineralization:
-- Disseminated bulk tonnage gold mineralization near surface ranging from
approximately 1 to 4 gpt at surface in the residual soils, the
underlying soft saprolite layer and near surface sandstones to a
vertical depth of approximately 30 metres;
-- Higher Grade (visible) gold mineralization (from 1 gpt up to 272 gpt) in
kaolinized sandstones immediately below the saprolite and extending to a
vertical depth of approximately 45 m;
-- High Grade (visible) gold mineralization (from 1 gpt up to 611 gpt)
hosted in a horizontal 25 metre thick basalt sill located 70 m below
surface;
-- Low Grade gold mineralization (1.5 to 2 gpt) hosted in a shale unit
below the basalt at 110 to 120 metres below surface.
Miles Rideout, President and CEO of the Company stated: "The Tacuru target is now validated as a major epithermal system with significant gold occurrences identified in several geological rock types. These results are impressive both for the high grades and that we continue to intersect gold mineralization from surface to 115 metres true depth. Expanded and deeper drilling will be required to fully evaluate this target."

The Tacuru Target is currently the most advanced exploration area on the 14.8 kilometre long X-Mile Trend, a linear feature defined by five gold soil geochemical anomalies ranging to over one kilometre in diameter each. The Tacuru target is the first of these targets to be drilled.
The X-Mile Trend runs parallel to the 4.5 kilometer Discovery Trend where the Company has constructed its Independencia Mine pilot operation. These trends, separated by 3.5 kilometres, and other outlying target areas suggest an epithermal mineralizing system approaching 100 square kilometre area.
About the Paso Yobai Gold Project:
The Company is operating the Independencia Mine Pilot Plant on the Company's 99%-owned mining concession, part of the Company's larger Paso Yobai Gold Project. The objective of the new pilot plant is to facilitate resource evaluation through bulk-sampling on the Discovery Trend, which is characterised by coarse gold mineralization extending from surface to greater than 100 m depth.
The X-Mile Trend at Paso Yobai is located on exploration licences that are 100% owned by the Company. The results of the Company's 2011 work to define drill targets suggest that bulk tonnage potential could exist at several target zones along this extensive structure. The Company continues to focus 2012 exploration on these targets.
About the Company:
Latin American Minerals Inc. is a mineral exploration company whose core projects include the Company's Independencia Mine and satellite targets in the new Paso Yobai gold district.
Dr. Waldo Perez is the Company's internal "Qualified Person" under the requirements of National Instrument 43-101 and has approved this press release.
Sampling and Analytical Protocols:
The sampling and analytical protocols were established, 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. At the drill site, the core was placed in core boxes and delivered to a secure field core processing centre. The core was "split" using a diamond saw by experienced exploration technicians and logged by professional geologists. The nominal sample interval was approximately 1m, though locally the interval might be increased to 2m or decreased to 0.5m, the interval being determined by the logging geologists based on geologic indicators. Half of the core was left in the core box as a permanent reference of the interval sampled and half of the designated sample interval was delivered to the Company's sample preparation facility, operated by Company technicians. The core samples were crushed, dried and split. A portion of the split sample was tagged and archived as coarse reject and the remaining portion ground to minus 200 mesh and shipped by bonded courier to the Alex Stewart Argentina S.A. laboratory in Mendoza, Argentina. All samples were assayed for gold and multi-elements by ICP. Gold was analyzed by Fire Assay with Atomic Absorption finish using 50 gram sample. For the multi-elements, the samples were dissolved in aqua regia and read in ICP-OES. Accuracy of results is tested through the systematic inclusion of blanks, duplicates and certified reference standards.
Metallic or Screen Fire Assays: Many exploration samples exhibit a pronounced "nugget" effect due to the presence of particulate gold in coarse fragments. The net result is a pronounced and unacceptable scatter in the gold analytical results making it difficult to assess the true gold concentration. To improve the analytical reproducibility a Metallic or "Screen" Assay is recommended. In the screen fire assay the sample is crushed, 400gr of pulp is sieved and the plus 100 micron (150 mesh) portion of the sample is screened out and assayed in its entirety. The minus 100 micron (150 mesh) portion of the sample is homogenized and a 50 gram fusion is used to determine its grade. Then the final assay reported is the weighted average of both fractions, coarse and fine.
