Other Significant Noncash Transaction, Description	On June 23, 2015, the Company raised net proceeds of $1.1 million through the sale of 12% of the cash flows Goldrich receives in the future from its interest in GNP (“Distribution Interest”), paid in cash under items #2 and #5 above, to Chandalar Gold, LLC (“CGL”), a non-related entity. Goldrich retained its ownership of its 50% interest in GNP but, after the transaction, subject to the terms of the GNP operating agreement, Goldrich will effectively receive approximately 44% and CGL will receive 6% (12% of Goldrich’s 50% of GNP = 6%) of any cash distributions produced by GNP. At September 30, 2017, the Company has an accrued liability of $8,110 for 12% of the $67,580 distribution made in 2016.
