Marathon Gold Corporation (TSX: MOZ) is pleased to report additional drill results from recent exploration drilling at the Valentine Gold Project, central Newfoundland. These latest results represent fire assay data from twenty-four drill holes located within the 6 kilometre long Sprite Corridor between the Frozen Ear Pond Road and the western margin of the Project’s Marathon Deposit. Highlights include:
All quoted intersections comprise uncut gold assays in core lengths. All significant assay intervals are reported in Table 1.
Matt Manson, President & CEO commented: “Over the last few months we have been releasing a series of encouraging drill results from the new Berry Zone at the Valentine Gold Project and its 1.5 kilometre northeastward extension to a road intersection referred to as the Frozen Ear Pond Road. The Berry Zone lies within the 6 kilometre long Sprite Corridor, midway between the Marathon and Leprechaun Deposits (Figure 1). The results released today represent the first drilling to be undertaken within the gap between the FEP Road and the westernmost margin of the Marathon Deposit. This 1.2 kilometre section of the Valentine Lake Shear Zone had previously been under-explored due to poor ground conditions limiting drill access. Sporadic gold mineralisation in characteristic QTP-Au veining was intercepted along most of this length. However, the strongest mineralization was seen in drill holes located closest to the Marathon Deposit between sections 16000E and 16200E. This suggests the potential for Marathon mineralization extending up to 200 metres southwest of the currently defined mineral resource pit shell. Additional drilling in this area is required to properly define this potential. The Marathon Deposit mineral resource estimate currently stands at 1.92 Moz of Measured and Indicated Mineral Resources (36.2 Mt at 1.65 g/t Au) and 0.67 Moz of Inferred Mineral Resources (10.57 Mt at 1.96 g/t Au).”
Drilling at the Valentine Gold Project has now been concluded for the 2020 season. Upcoming results that remain to be released include assays from 8,680 metres of drilling in forty holes from within the Berry Zone, 3,471 metres of drilling in nineteen holes from the northeastern extension between Berry and the FEP Road, and a further 2,260 metres in fourteen holes from the Narrows prospect located northeast of the Marathon Deposit. These results are expected to be released in batches through the end of the year and into January, with a first mineral resource estimate for Berry expected towards the end of Q1 2021.
Gold mineralization at the Valentine Gold Project is contained predominantly within shallowly southwest dipping, en-echelon stacked Quartz-Tourmaline-Pyrite-Gold veins. At the Leprechaun and Marathon Deposits, as well as at the new Berry Zone, these QTP-Au veins form densely stacked and northwest plunging “Main Zone” envelopes within intrusive host rocks on the hanging wall (northwest) side of the Valentine Lake Shear Zone. The extent of mineralization appears related to the size and frequency of sheared mafic dykes which extend northeast-southwest within the hanging wall, parallel to the shear zone. Exploration drilling is generally undertaken in two orientations: down steeply towards the northwest at a high angle to the individual veins and down-plunge of the Main Zone stacking, or obliquely towards the southeast sub-parallel to the individual veins and across the strike of Main Zone mineralization.
The results released today are derived from twenty-four drill holes located between sections 15000E at the FEP Road and section 16200E at the westernmost limit of the mineral resource pit shell for the Marathon Deposit. Fourteen holes were oriented steeply down to the northwest testing for “Main Zone” type stacked QTP-Au mineralization (MAS-20-001, 002, 003, 007, 008, 009, 011, 012, 014, 016, 018, 019, 023 and 024) and ten holes were oriented to the southeast drilling from the hanging wall towards the footwall contact (MAS-20-004, 005, 006, 010, 013, 015, 017, 020,021 and 022; Figures 2 and 3).
Overall, twenty of the twenty-four drill holes returned “significant” drill intersections of greater than 0.7 g/t Au (Table 1). Twenty-three of the twenty-four holes returned intersections with gold grades above the 0.3 g/t Au cut-off used in the January 2020 Mineral Resource Estimate for the Project. No economic mineralization was encountered in drill hole MAS-20-006.

Quality Assurance-Quality Control
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, NL. All reported core samples are analyzed for Au by fire assay (30g) with AA finish. All samples above 0.30 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 (70 – 95% of core length), and reported with and without a top-cut of 30 g/t Au applied.

Marathon is a Toronto based gold company advancing its 100%-owned Valentine Gold Project located in the central region of Newfoundland and Labrador, 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 Pre-Feasibility Study outlined an open pit mining and conventional milling operation over a twelve-year mine life with a 36% after-tax rate of return. The Project has estimated Proven Mineral Reserves of 1.3 Moz (26.3 Mt at 1.52 g/t) and Probable Mineral Reserves of 0.6 Moz (14.8 Mt at 1.23 g/t). Total Measured Mineral Resources (inclusive of the Mineral Reserves) comprise 1.9 Moz (31.7 Mt at 1.86 g/t) with Indicated Mineral Resources (inclusive of the Mineral Reserves) of 1.19 Moz (23.2 Mt at 1.60 g/t). Additional Inferred Mineral Resources are 0.96 Moz (16.77 Mt at 1.78 g/t Au).
