Other Assets	Soyatal Included in Other Assets at September 30, 2013 are credits of approximately $379,000 for advances we have made to the previous Soyatal operator for equipment and antimony ore mill feed which we plan to utilize as an offset for future option payments on the Soyatal property. Guadalupe In March of 2012 we entered into a supply agreement with Grupo Roga or “Guadalupe” for antimony ore. As of September 30, 2013 we had received approximately 1,725 metric tons of antimony ore under this agreement. In 2012 and 2013 we made advances to Guadalupe to fund their antimony mining operations. The mining, trucking, and milling costs on this ore have exceeded its value by approximately $393,000. As Guadalupe has agreed to deduct these excess costs through future antimony ore purchases and (or) option payments for the Guadalupe property, we have recorded the excess costs as Other Assets at September 30, 2013.
