South American Silver Reports Updated Positive Metallurgy at Malku Khota Friday April 11, 9:00 am ET ca.us.biz.yahoo.com VANCOUVER, BRITISH COLUMBIA--(MARKET WIRE)--Apr 11, 2008 -- South American Silver Corp. ("SASC" or the "Company"), (Toronto:SAC.TO - News), is pleased to announce that it has completed the next series of laboratory tests on two samples from the Malku Khota silver-indium-gold project in Bolivia. The latest heap leach amenability tests were performed on two samples to test for the extraction of silver and indium, using coarser material than was used in the initial tests. The coarser material in these latest tests is intended to give results that are more representative of extractions that would be expected in a commercial heap leach application. The results of these latest tests are very encouraging. --------------------------------------------------------------------------- SAMPLE Silver % Indium % Silver Head Indium Head Grade (gpt) Grade (gpt) --------------------------------------------------------------------------- Met 1 62.9 77 52.3 20 --------------------------------------------------------------------------- Met 2 96.9 61 73.0 41 --------------------------------------------------------------------------- The two samples were ground to 10 mesh (2,000 microns) and were treated with an acid solution plus salt (NaCl) and an oxidant over a 14 day period. The test results demonstrate that both the silver and the indium can be extracted in the same solution using this technique. These extractions will be further optimized in future tests. Ralph Fitch, President of the Company, stated that "These results, although still at an early stage, are important for two reasons. First, the extraction was made using coarsely ground material so the results more closely match what we might get in a heap leach and second, the process extracts both silver and indium at the same time as well as some other potentially recoverable metals such as copper, lead and zinc". A second series of tests is ongoing using a standard "cyanide leach" procedure on this coarser 10 mesh material. Intermediate results have been mixed with some extractions being as high as the acid leach while others are lower. The ongoing tests are experimenting with various reagent concentrations and the length of the leach process. The Company will report these results once this latest test series is completed. Metallurgical testing will continue with these same samples and a new series of samples from the deposit so that reagent use, grain size and extraction time can be better optimized both for conventional gold leach and the acid plus salt leach process. The Malku Khota metallurgical program is being directed by Dr. David Dreisinger, consultant to the Company and Professor and Chair of Industrial Research in Hydrometallurgy at the University of British Columbia. The metallurgy testing was carried out at the SGS Lakefield Laboratory in Ontario.
