SPOKANE, WA - October 18, 2017- Goldrich Mining Company (OTCBB: GRMC) ('Goldrich' or the 'Company) is pleased to announce the 2017 production results for the Chandalar Mine. The Chandalar mine is owned by Goldrich NyacAU Placer, LLC ('GNP'), a 50/50% joint venture between Goldrich and NyacAU, to mine the various placer deposits that occur throughout Goldrich's 23,000-acre Chandalar gold project in Alaska. NyacAU is the manager of the joint venture.

2017 Production Summary
The Chandalar mine production for 2017 was 14,670 ounces of raw placer gold, which is approximately equivalent to 12,000 ounces of fine gold. This compares to 10,209 ounces of raw gold, or approximately 8,200 ounces of fine gold, produced in 2016 and 4,400 ounces of raw gold, or approximately 3,600 ounces of fine gold, produced in 2015.

Per the terms of the joint venture operating agreement, GNP is required to make a payment of approximately $1.3 million (1,100 ounces X $1,201 per ounce) to Goldrich for the 2016 Minimum Production Requirement and approximately $1.4 million (1,200 ounces X $1,201 per ounce) for the 2017 Minimum Production Requirement. The Minimum Production Requirement for 2018 will be determined based on the spot price of gold on December 1, 2017. The Minimum Production Requirement payments for 2016, 2017 and 2018 are due by October 31, 2018. Assuming a spot price of gold of $1,201, the total 2018 Minimum Production Requirement will be $1.6 million (1,300 ounces X $1,201 per ounce) and the total required payments to Goldrich from GNP on October 31, 2018 will be approximately $4.3 million (3,600 ounces X $1,201 per ounce).

The 2017 production season ran from approximately June 4, 2017 through September 27, 2017. The normal production season is approximately from mid-June through mid-September, subject to weather. In addition, stripping of overburden and stockpiling of pay gravel can usually be done for at least one month before and after the production season. Stripping of overburden this year continued through October 17, 2017.
