Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | In 2005, AM signed an option agreement that gives AM the exclusive right to explore and develop the San Miguel I and San Miguel II concessions for annual payments. Total payments will not exceed $1,430,344, reduced by taxes paid. During the years ended December 31, 2013, 2012, and 2011, $130,434, $86,956, and $186,956, respectively, was paid and capitalized as mineral rights in accordance with the Company’s accounting policies. At December 31, 2013, approximately $450,000 of option payments are scheduled to be paid in June 2014. From time to time, the Company is assessed fines and penalties by the Mine Safety and Health Administration (“MSHA”). Using appropriate regulatory channels, management may contest these proposed assessments, and has accrued $7,909, $0 and $27,503 in other accrued liabilities as of December 31, 2013, 2012, and 2011, respectively, related to these settled claims. We are subject to the income tax laws of foreign income laws of foreign countries. We are not aware of any liabilities for foreign income taxes that should be accrued at year end, and to the best of our knowledge none exist.
