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 initially shipped by Hillgrove, 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 is five 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. At March 31, 2017, the net amount due to Hillgrove for advances was $1,134,216. As of March 31, 2107, repayment of the advances is not expected to occur within the next twelve months so the balance is classified as a long term liability.
