About Marathon Gold Corp.

Marathon is a Toronto-based gold company advancing its 100-per-cent-owned Valentine gold project located in central Newfoundland, one of the top mining jurisdictions in the world. The project comprises a series of four mineralized deposits along a 20-kilometre system. An April, 2020, prefeasibility study outlined an open-pit mining and conventional milling operation over a 12-year mine life with a 36-per-cent after-tax rate of return. The project has estimated proven mineral reserves of 1.3 million ounces (26.3 million tonnes at 1.52 grams per tonne) and probable mineral reserves of 600,000 ounces (14.8 million tonnes at 1.23 g/t) and total measured mineral resources (inclusive of the mineral reserves) of 1.9 million ounces (31.7 million tonnes at 1.86 g/t) and indicated mineral resources (inclusive of the mineral reserves) of 1.19 million ounces (23.2 million tonnes at 1.6 g/t). Additional inferred mineral resources are 960,000 ounces (16.77 million tonnes at 1.78 g/t Au). Please see the technical report dated April 21, 2020, for further details and assumptions relating to the Valentine gold project.
