Latin American Minerals delineates new rare earth elements targets at its Chirigueloniobium/REE project in Paraguay

TORONTO, ONTARIO–(Marketwire – Sept. 27, 2011) – Latin American Minerals Inc. (TSX VENTURE:LAT) (the “Company“) announces selected interim results from 2011 ground exploration program at the Chiriguelo Project, located in northern Paraguay near the border with Brazil. Recentrock and soil samples have detected a second Rare Earth Element (REE) target. Previous exploration at the project had delineated a significant niobium (Nb) target and the original Chiriguelo Rare Earth Element target. Carbonatites similar to Chiriguelo include the world’s largest niobium deposits, the Araxá and Catalão mines in Brazil, and also large rare earth deposits such as Mountain Pass in California and Mount Weld in Australia.

In May 2011, the Company initiated a detailed ground exploration program at Chiriguelo designed to detect and delineate new areas of REE or Nb concentrations. The program involves comprehensive grid coverage of ground magnetics, ground radiometrics, and soil and rock sampling. While this eight month program remains ongoing, partial results have identified a new second REE target with high values over a 2000 metre by 2000 metre area.

Miles Rideout, President and CEO of Latin American Minerals Inc. said: “This remarkable REE target validates our interest in this new exploration region, where we believe the Company has the potential to ultimately define a rare earth element resource. Latin American Minerals has a strong track record where we have previously identified and developed an industrial resource project, which culminated in our Lithium Americas spin-off IPO in 2010. If we can prove a viable resource in the critical REE market or niobium sector, a similar spin-off or a strategic partnership with a major company are possible development alternatives.”

The results are summarized below for Total Rare Earth Oxides (TREO). The actual upper quartile results are shown in Table 1.

46 rock samples were collected at surface though the target area.
  • The average for all these rock samples was 0.93 % TREO.
  • The average for the upper quartile for rock samples was 2.53% TREO.
  • The highest concentration recorded in rock samples was 5.89% TREO.
100 soil samples were collected over a regular grid though the anomalous area.
  • The average for all these soil samples was 0.298 % TREO.
  • The average for the upper quartile for soil samples was 0.77% TREO.
  • The highest concentration recorded in soil samples was 1.41% TREO.

Table 1: Summary of upper quartile TREO values from the sample set over the new REE target area.

Considering only the upper quartile set of rock samples, the distribution of the major REOs within the TREO value is: 50.94% Cerium (Ce), 36.27% Lanthanum (La), 7.86 Neodymium (Nd), 3.83% Praseodymium (Pr), 0.67% Yttrium (Y) and 0.43% Samarium (Sm).The assays were conducted by ALS Minerals in Peru employing lithium borate fusion followed by acid dissolution and ICP-MS analysis.

Paraguay is a progressive democratic county with legislation favorable for foreign investment, mine operation and exports. Chiriguelo, as with all the Company’s projects in Paraguay, features all-weather road access and proximal population centres for logistical support.
