(OTCID:XTPT), today announced excellent test results using material sourced from the Company's Antimony King Mine within the American Antimony Project in Bernice Canyon, Nevada. The test work was completed by ALS Metallurgy of Kamloops, BC, under the supervision of International Metallurgical and Environmental Inc. Historically, the Antimony King Mine has produced high-grade materials for the recovery of antimony. Test work results indicate that a simple flotation process can produce very high-grade antimony concentrates of approximately 63 percent antimony, at very high antimony recoveries of approximately 97 percent of the contained antimony.\r\n A bulk sample of approximately 400 kilograms was provided to ALS Metallurgy for test work purposes. The test work program consisted of mineralogical evaluation, preliminary flotation tests and production of a bulk concentrate sample. Shown in the following two tables are detailed analysis of the bulk sample chemistry and the key mineralogical results provided by ALS Metallurgy.\r\n ANALYSIS OF AMERICAN ANTIMONY BULK SAMPLE\r\n \r\n \r\n \r\n \r\n Sample\r\n \r\n \r\n Assay - percent or g/tonne\r\n \r\n \r\n \r\n \r\n Sb\r\n \r\n \r\n Fe\r\n \r\n \r\n S\r\n \r\n \r\n Au\r\n \r\n \r\n Ag\r\n \r\n \r\n \r\n \r\n American Antimony Bulk Sample\r\n \r\n \r\n 30.2\r\n \r\n \r\n 0.9\r\n \r\n \r\n 12.4\r\n \r\n \r\n 0.28\r\n \r\n \r\n 10.4\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n MINERAL COMPOSITION OF AMERICAN ANTIMONY BULK SAMPLE\r\n \r\n \r\n \r\n \r\n Minerals\r\n \r\n \r\n Mineral Content%\r\n \r\n \r\n \r\n \r\n Stibnite\r\n \r\n \r\n 41.8\r\n \r\n \r\n \r\n \r\n Antimony Oxides\r\n \r\n \r\n 0.8\r\n \r\n \r\n \r\n \r\n Pyrite\r\n \r\n \r\n 0.4\r\n \r\n \r\n \r\n \r\n Arsenopyrite\r\n \r\n \r\n 0.2\r\n \r\n \r\n \r\n \r\n Other Sulphide Minerals\r\n \r\n \r\n 0.3\r\n \r\n \r\n \r\n \r\n Iron Oxides\r\n \r\n \r\n 1.0\r\n \r\n \r\n \r\n \r\n Quartz\r\n \r\n \r\n 47.8\r\n \r\n \r\n \r\n \r...
