Other Assets	Soyatal Included in Other Assets at June 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 to our purchase of the Soyatal property or offset from future ore purchase payments which may become due to Soyatal. Guadalupe In March of 2012 we entered into a supply agreement with Grupo Roga or “Guadalupe” for antimony ore. As of June 30, 2013 we had received approximately 26 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 $335,000. 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 June 30, 2013.
