Hillgrove Advances Payable
Hillgrove Advances Payable	On November 7, 2014, the Company entered into a loan and processing agreement with Hillgrove Mines Pty Ltd of Australia (Hillgrove) by which Hillgrove will advance the Company funds to be used to expand their smelter in Madero, Mexico, and in Thompson Falls, Montana, so that they may process antimony and gold concentrates produced by Hillgrove’s mine in Australia. The agreement requires that the Company construct equipment so that it can process approximately 200 metric tons of concentrate per month, with a provision so that the Company may expand to process more than that. The parties agreed that the equipment will be owned by USAC and USAMSA. The final terms of when the repayment takes place have not yet been agreed on. The agreement called for the Company to sell the final product for Hillgrove, and Hillgrove to have approval rights of the customers for their products. The agreement allows the Company to recover its operating costs as approved by Hillgrove, and to charge a 7.5% processing fee and a 2.0% sales commission. The initial term of the agreement was five years, and that agreement was amended later to be eight years; however, Hillgrove may suspend or terminate the agreement at its discretion. The Company may terminate the agreement and begin using the furnaces for their own production if Hillgrove fails to recommence shipments within 365 days of a suspension notice. If a stop notice is issued between one year and two years, there is a formula to prorate the repayment amount from 50% to 81.25%. If a stop order is issued after two years, the repayment obligation is 81.25% of the funds advanced at that point. At December 31, 2015, management determined that it is likely that the Company’s repayment obligation will be 81.25% of the total amounts advanced. As of June 30, 2016, Hillgrove had advanced the Company approximately $1.4 million. The Company had transferred or constructed plant and equipment valued at $1,580,630 for the benefit of Hillgrove. Of this amount, $262,500 has been recorded as deferred earned credit and is being recognized ratably through the period ending November 7, 2016 which is when the 81.25% repayment terms of the agreement is applicable. During the six months ended June 30, 2016 and 2015, $76,579 and $58,139, respectively, of the deferred earned credit was recognized with $43,750 to be recognized in the remainder of 2016. At June 30, 2016, the amount due to Hillgrove for advances was $1,134,221 which is approximately 81.25% of the total amount advanced.
