Marathon Gold Reports Additional Drill Results from Berry Zone at the Valentine Gold Project

TORONTO, Aug. 17, 2020 - Marathon Gold Corp. (“Marathon” or the “Company”; TSX: MOZ) is pleased to report drill results from recent exploration drilling at the Valentine Gold Project, central Newfoundland (the “Project”). These latest results represent fire assay data from the latest nine drill holes completed in the new Berry Zone, located within the six-kilometre long Sprite Corridor. Highlights include:

• VL-20-835 intersected 2.96 g/t Au over 47 metres, including 7.55 g/t Au over 14 metres, and 32.25 g/t Au over 1 metre, and 27.00 g/t Au over 1 metre;
  
  
• VL-20-834 intersected 2.23 g/t Au over 30 metres, including 6.53 g/t Au over 8 metres;
  
  
• VL-20-829 intersected 2.12 g/t Au over 20 metres including 16.89 g/t Au over 1 metre, and 2.26 g/t Au over 10 metres, and 1.03 g/t Au over 17 metres, and 1.02 g/t Au over 11 metres;
  
  
• VL-20-831 intersected 1.82 g/t Au over 10 metres; and
  
  
• VL-20-830 intersected 0.93 g/t Au over 14 metres.

All quoted intersections comprise uncut gold assays in core lengths. All significant assay intervals are reported in Table 1.

Matt Manson, President & CEO commented: “The latest batch of drill assays from the new Berry Zone include additional long intersections of high-grade mineralization. The mineralization occurs in the familiar geological setting: quartz-tourmaline-pyrite veining developed in the hanging-wall of the Valentine Lake Shear Zone within “Main Zone” type configurations. The drilling is establishing broad continuity between 50 metre sections, and has extended the zone to approximately 650 metres in strike length.” Matt Manson continued: ”Our 2020 exploration program is focused on new discovery, with broad step out holes into previously untested areas. Currently, one drill rig is progressing steadily northeastwards from Berry to the area of the “Frozen Ear Pond Road”, approximately 1.5 kilometres from where we started in January. An additional drill rig is scheduled to be mobilized in early September, exploring southwestwards from the margin of the Marathon Deposit towards Frozen Ear Pond Road. At the end of this campaign we will have drilling information along the full 6 kilometres of the Sprite Corridor between Leprechaun and Marathon. This is high-risk, greenfield exploration, with no certainty of success. However, the results achieved to date at the Berry Zone give confidence in the potential for additional discoveries along this highly prospective trend.”

Previous drilling in the Berry Zone (Figure 1) has outlined extensive gold mineralization contained within shallowly southwest dipping, en-echelon stacked Quartz-Tourmaline-Pyrite-Gold (“QTP-Au”) veins that are characteristic of the Valentine Gold Project. These QTP-Au veins form steeply northwest plunging “Main Zone” envelopes within quartz-eye porphyry host rocks on the hanging-wall (NW) side of the Valentine Lake Shear Zone. The extent of mineralization appears related to the size and frequency of sheared mafic dykes which extend NE-SW within the hanging-wall, parallel to the shear zone.

The nine drill holes released today represent both step out and in-fill drilling over a broad length of the Berry Zone. They extend the strike length of drill intersected mineralization to approximately 650 metres, from section 13350E to 14000E (Figure 2). An area of particularly intense mineralization has now been intersected by several drill holes between sections 13600E and 13800E where QTP-Au veining is concentrated in a 30-50 metre wide zone between a large mafic dyke and the shear zone contact (eg Section 13790E, Figure 3, and Section 13690E from Marathon’s news release dated July 22, 2020).

These latest results are derived from drill-holes oriented steeply down through Main Zone QTP-Au stacking towards the northwest (VL-20-829, 830, 831, 834 & 835, Figures 3 and 4), oblique drill-holes across Main Zone mineralization towards the southeast (VL-20-828 & 833), and one drill-hole collared in the hanging-wall and oriented towards the northwest (VL-20-836). Eight of the nine holes returned “significant” drill intersections of greater than 0.7 g/t Au (Table 1), and each of the nine drill holes returned drill 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 significant mineralization was encountered in drill hole VL-20-832, which was collared in the meta-sediments of the southeastern, foot-wall side of the Valentine Lake Shear Zone.

Notes on the Calculation of Assay Intervals

1. “Significant” assay intervals are defined as 1m core length or more of mineralization with an average fire assay result of greater than 0.7 g/t Au, representing the bottom cut-off for high-grade mill feed in the Marathon April 2020 Pre-Feasibility Study mine plan (see technical report dated April 21, 2020). Assay intervals with an average fire assay result of between 0.3 g/t Au and 0.7 g/t Au are above the cut-off used in the January 2020 Mineral Resource Estimate for the Project but are not considered “significant” for the purposes of this news release.
2. No significant assays were returned in drill hole VL-20-832

Qualified Person

Disclosure of a scientific or technical nature in this news release was prepared under the supervision of Nicholas Capps, P.Geo. (NL), Project Manager for exploration at the Valentine Gold Project. Exploration data quality assurance and control for Marathon is under the supervision of Jessica Borysenko, P.Geo (NL), GIS Manager for Marathon Gold Corp.. Both Mr. Capps and Ms. Borysenko are qualified persons 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, 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.
