Proceeds from sale of cash flow percentage
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. As part of the purchase, CGL received 2,250,000 Series P Warrants and an option to acquire an additional 10% Distribution Interest in the cash flows Goldrich receives from its interest in GNP. Each Series P Warrant is exercisable to purchase one share of common stock of the Company at $0.07, for a period of five (5) years. The lead agent for the sale received a commission equal to 5% of gross proceeds raised, was granted a perpetual undivided 0.5% interest in distributions paid out by GNP to Goldrich, and was issued 1.2 million Series P-2 Warrants. Each Series P-2 Warrant is exercisable into one share of common stock of the Company for a period of five (5) years at a price of $0.05 per share.
