Goldrich Mining Announces Commencement of 2017 Mining Season and Drill Program at Chandalar Mine

Spokane, Washington--(Newsfile Corp. - June 8, 2017) - Goldrich Mining Company GRMC ("Goldrich" or the "Company) is pleased to announce Goldrich NyacAU Placer, LLC ("GNP") has commenced mining at the Chandalar gold project in Alaska. Mining of pay gravel is expected to continue through mid-September, subject to weather conditions.

The Chandalar mine is owned by Goldrich NyacAU Placer, LLC ("GNP"), a 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 acts as project manager.

2017 Production Forecast

GNP's revised forecast for 2017 production is approximately 13,500 ounces of fine gold at a cost of approximately US$700 per ounce. This compares to actual production of 3,857 and 8,227 ounces of fine gold in 2015 and 2016, respectively, and a 2016 cost of approximately US$960 per ounce. Final numbers for the 2017 forecast and the 2016 costs may change as Goldrich and NyacAU are currently in discussions concerning certain accounting items.

The revised 2017 forecast assumes 109 days of plant operation, 19 hours a day, with a processing rate of 308 bank cubic yards ("bcy") per hour. In 2016, the plant operated approximately 15 hours a day at a processing rate of 183 bcy per hour.

GNP has made modifications to the plant to increase efficiency since 2016. Total plant capacity after modifications is budgeted to increase approximately 119% to 400 bcy per hour.

Drill Program

Beginning in June, GNP plans to conduct a 122-hole sonic drill program. Drill hole footage is expected to total 7,700 feet with an average hole depth of 63 feet. The drill plan is designed to further define mineralized placer material between Line 8.6 to Line 12 as well as test for potential mineralized material from Lines 13 to 17.5. Each Line is approximately 500 feet apart and drill lines will be spaced roughly 250 feet apart.

Goldrich previously completed a reverse circulation drill program that delineated approximately 10.5 million cubic yards of mineralized material at an average grade of 0.025 ounces (0.78 grams) gold per cubic yard containing an estimated 250,000 ounces of gold⁽¹⁾. In 2016, GNP surveyed the area beyond Line 11 and received a permit to mine Lines 11 to 18 in addition to permits already received to mine from Line 1 to Line 11. GNP work indicates the gold mineralization extends further along strike beyond Line 11.

(1) This mineralized material is not a mineral reserve as defined in SEC Industry Guide 7.
