Marathon Gold Reports New Drill Results from Marathon Deposit at Valentine Gold Project, NL

Marathon Gold Corporation (“Marathon” or the “Company”) (TSX: MOZ) is pleased to announce positive results from the ongoing infill drilling campaign at the Marathon Deposit, part of the Valentine Gold Project in central Newfoundland. The new drilling continues to successfully demonstrate the occurrence and continuity of gold mineralization both along and across strike of the 1,500-meter long “Main Zone” within the Marathon Deposit, as well as from surface to the base of the currently planned open pit, where mineralization remains open to depth. In particular, the latest results confirm significant new zones of gentle SW-dipping, en-echelon stacked Quartz-Tourmaline-Pyrite-Gold (“QTP-Au”) veining in areas of limited previous drilling within the southwestern area of the planned Marathon open pit. Highlights of the latest drilling include:

• Main Zone: MA-19-430 intersected 4.64 g/t Au over 29.0 meters including 18.41 g/t Au over 3.0 meters and 9.00 g/t Au over 2.0 meters, and 2.08 g/t Au over 15.0 meters including 7.44 g/t Au over 2.0 meters.

• Main Zone: MA-19-434 intersected 2.36 g/t Au over 39.0 meters including 7.03 g/t Au over 6.0 meters, 17.03 g/t Au over 1.0 meters and 11.42 g/t Au over 1.0 meters, as well as 4.55 g/t Au over 9.0 meters including 8.34 g/t Au over 2.0 meters.

• Main Zone: MA-19-431 intersected 3.38 g/t Au over 29.0 meters including 16.37 g/t Au over 3.0 meters, and 3.32 g/t Au over 3.0 meters.

• Main Zone: MA-19-429 intersected 2.22 g/t Au over 25.0 meters including 7.31 g/t Au over 4.0 meters, and 4.24 g/t Au over 3.0 meters.

• Main Zone: MA-19-435 intersected 1.90 g/t Au over 26.0 meters including 7.42 g/t Au over 3.0 meters, as well as 9.27 g/t Au over 3.0 meters and 7.52 g/t Au over 3.0 meters.

• Main Zone: MA-19-413 intersected 2.33 g/t Au over 20.0 meters including 11.79 g/t Au over 2.0 meters, and MA-19-419 intersected 2.55 g/t Au over 12.0 meters including 7.33 g/t Au over 2.0 meters.

• Main Zone: MA-19-424 intersected 6.89 g/t Au over 3.0 meters, MA-19-425 intersected 5.34 g/t Au over 3.0 meters, MA-19-426 intersected 6.14 g/t Au over 4.0 meters and MA-19-427 intersected 5.33 g/t Au over 3.0 meters.

• Main Zone NE: MA-19-418 intersected 3.72 g/t Au over 10.0 meters including 10.66 g/t Au over 3.0 meters, and 2.11 g/t Au over 14.0 meters including 6.36 g/t Au over 2.0 meters, MA-19-417 intersected 4.67 g/t Au over 5.0 meters, and MA-19-412 intersected 10.61 g/t Au over 3.0 meters.

The latest drilling has been oriented downward at a high-angle through the en-echelon stacked, shallowly SW dipping QTP-Au veins which form the dominant vein orientation within the sub-vertical Main Zone corridor of the Marathon Deposit (Table 1; Figure 1). It represents infill drilling in areas currently classified as Inferred Mineral Resources in the October 2018 Mineral Resource Estimate. Assays are pending for additional new drill holes which have also intersected significant QTP-Au veining in areas of limited previous drilling in the southwest Main Zone corridor.

Three drill rigs are currently operating at the Marathon Deposit. Based on the results achieved to date, additional drilling has been approved in the southwest extension area of the Marathon Deposit, both infill and exploratory. This will bring the total meterage to be drilled at the Marathon and Leprechaun Deposits in 2019 to approximately 60,000 meters. This extended program is expected to be completed by mid-October. Thereafter, two drill rigs will move on to complete a planned 7,000-meter exploration drilling campaign at the Sprite Zone.

All drilling completed to the middle of October will be utilized in the upcoming Mineral Resource update for the Valentine Gold Project, expected to be completed in the fourth quarter of this year.

In addition to the exploration drilling, hydrogeology drilling and geotechnical test pitting programs will be completed in October, the results of which will be used in infrastructure design for the upcoming Valentine Pre-Feasibility study scheduled for the second quarter of 2020.

Disclosure of a scientific or technical nature in this press release was prepared under the supervision of Sherry Dunsworth, MSc., P.Geo. (NL), the Senior VP of Exploration and a qualified person under National Instrument (“NI”) 43-101.

Quality Assurance-Quality Control (“QA/QC”)

QA/QC protocols followed at the Valentine Gold Project include 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% – 95% of core length).

About Marathon

Marathon is a Toronto based gold company rapidly advancing its 100%-owned Valentine Gold Project located in central Newfoundland, one of the top mining jurisdictions in the world. The Valentine Gold Project comprises a series of mineralised deposits along a 20-kilometer system of gold bearing Quartz-Tourmaline-Pyrite veins. The project is accessible by year-round road and is in close proximity to the provincial electrical grid. To date, four gold deposits at Valentine have been delineated, including the large Leprechaun and Marathon deposits. An October 2018 Preliminary Economic Assessment showed the project to be amenable to open pit mining and conventional milling over a twelve-year mine life. Total Mineral Resources currently comprise Measured Mineral Resources of 16.6 million tonnes at a grade of 2.18 g/t containing 1,166,500 oz. of gold, Indicated Mineral Resources of 28.5 million tonnes at a grade of 1.66 g/t containing 1,524,900 oz. of gold and Inferred Mineral Resources of 26.9 million tonnes at a grade of 1.77 g/t containing 1,531,600 oz. of gold. For more information, readers are referred to the technical report prepared in accordance with the requirements of NI 43-101 dated October 30, 2018 for further details and assumptions relating to the project.
