Quality Assurance-Quality Control ("QA/QC")

Sherry Dunsworth, M.Sc., P. Geo., SVP of Exploration, Marathon's Qualified Person, has reviewed the contents for accuracy and has approved this press release on behalf of Marathon. Thorough QA/QC protocols are followed including the insertion of blanks and standards at regular intervals in each sample batch. Drill core is cut in half with one half retained at site, the other half tagged and sent to Eastern Analytical Limited in Springdale, Newfoundland. All reported core samples are analyzed for Au by fire assay (30g) with AA finish. All samples above 0.10 g/t Au in economically interesting intervals are further assayed using metallic screen to mitigate the presence of coarse gold. Significant mineralized intervals are reported in Table 1 as core lengths and estimated true thickness (80% to 95% of core length).

About Marathon Gold

Marathon Gold Corporation (TSX: MOZ) is a gold exploration company rapidly advancing its 100% owned Valentine Lake Gold Camp located in Newfoundland, one of the top mining jurisdictions in the world. The Valentine Lake property currently hosts four near-surface, mainly pit-shell constrained, gold resources totaling 1,388,200 oz. gold at 1.91 g/t (Measured & Indicated) and 766,500 oz. gold at 2.24 g/t (Inferred), (February 2017). These resources occur over a 20-km system of gold bearing veins. Much of the 24,000-hectare property has not been explored in detail to date. Drilling in 2017 will continue to focus on expanding the Marathon Deposit at surface and to depth. The property is accessible by year-round round, and is located within Newfoundland's electrical grid. The Company has constructed and maintains a 50-person all-season camp at the project. Recent metallurgical tests have demonstrated 93% to 98% recoveries via conventional milling and 50% to 70% recoveries via low cost heap leaching at both the Leprechaun and Marathon Deposits.
