Leprechaun’s High-Grade Core Extend for >600 Meters in Main Zone: New DDH’s Intersect 4.49 g/t Au over 41.0m, 4.49 g/t Au over 14.0m and 10.33 g/t Au over 11.0m, Valentine Gold Camp, NL

Drilling Highlights:

Leprechaun Deposit infill drilling along the Main Zone of the deposit continues to intersect new high-grade gold intervals with abundant visible gold and now delineates a high-grade core area of the Main Zone that extends for more than 600-meters along strike (Figure 1, 2 and 3). The Main Zone corridor of the Leprechaun Deposit consists of dominantly shallow SW dipping en-echelon stacked QTP-Aug veins within an enveloping surface that dips 65 degrees to the northwest, extends along strike for more than 950 meters, has a true width ranging from 30 to 120 meters, and extends from surface to more than 300 meters depth; to the bottom of the open pit and beyond (see Figures 1, 2 and 3). The new drilling along the Main Zone is orientated downward at high-angle to and through the shallow SW dipping en-echelon stacked QTP- Au veining and verifies the continuity of the high-grade gold zone from surface to depths greater than 300 meters, a fact particularly significant in areas of limited previous drilling along the northeastern portion of the Main Zone gold corridor.

• Main Zone: VL-19-719 intersected 4.49 g/t Au over 41.0 meters including 23.04 g/t Au over 2.0 meters, 15.57 g/t Au over 2.0 meters, and 10.78 g/t Au over 2 meters, 10.33 g/t Au over 11.0 meters including 22.04 g/t Au over 5.0 meters, and 3.28 g/t Au over 21.0 meters including 11.56 g/t Au over 4.0 meters. This hole was drilled parallel and flanking drill hole VL-19-711, assisting in further defining the outer margin of the high-grade Main Zone (Figure 2).
  
• Main Zone: VL-19-725 intersected 3.20 g/t Au over 16.0 meters including 10.62 g/t Au over 2.0 meters and 5.52 g/t Au over 2.0 meters, as well as 2.57 g/t Au over 10.0 meters near surface (Figure 3).
  
• Main Zone: VL-19-722 intersected 6.61 g/t Au over 8.0 meters including 25.31 g/t Au over 2.0 meters, and 2.23 g/t Au over 24.0 meters.
  
• Main Zone: VL-19-717 intersected 3.32 g/t Au over 17.0 meters including 17.31 g/t Au over 2.0 meters, as well as 3.32 g/t Au over 8.0 meters and 2.60 g/t Au over 9.0 meters.
  
• Main Zone: VL-19-727 intersected 4.49 g/t Au over 14.0 meters including 12.45 g/t Au over 4.0 meters as well as 3.53 g/t Au over 4.0 meters.
  
• Hanging Wall DDH’s, drilled towards the southeast, intersected significant gold mineralization in both the hanging wall and at deeper levels of the Main Zone corridor including 2.02 g/t Au over 26.0 meters with 6.22 g/t Au over 3.0 meters in VL-19-719, and 5.60 g/t Au over 6.0 meters in VL-19-721.
  
• The high-grade gold core of the Main Zone corridor of the Leprechaun Deposit now extends continuously for more than 600 meters along strike, extends from surface to a depth of more than 300 meters, and has a true width that ranges from 30 meters to more than 100 meters. Additional planned drilling is expected to increase the strike length of the high-grade core of the Main Zone corridor towards both the northeast and southwest.
  
• The 2019 drilling is completed at the Leprechaun Deposit with assays outstanding for VL-19-728 to VL-19-747. The 3 drill rigs have moved to the Marathon Deposit where a 17,000 meter infill and step out drilling program will be completed before the drills move on to complete a 7,000 meter exploration drilling campaign at the Sprite Zone in fall 2019.
  
• A 2,250 meter HQ core size geotechnical drilling program is now underway with the 4^th drill rig currently drilling in the Marathon Deposit. This geotechnical drilling program is designed to test the open pit wall strength at both the Leprechaun and Marathon deposits. This work is being completed in advance of the PFS on schedule for release Q1 of 2020.

TORONTO, July 25, 2019 -- Marathon Gold Corp. (“Marathon” or the “Company”) (TSX: MOZ) is pleased to announce the continued success from the infill drilling along the Main Zone corridor of the Leprechaun Deposit. These drill holes, as well as the previously released 2019 drill holes collared along the upper edge of the Main Zone corridor (refer to Figure 1), are part of the series of planned infill drill holes that will cover a more than 800-meter strike length of the Main Zone corridor. These drill holes are designed to penetrate down through the shallow SW dipping, stacked gold-bearing QTP veins which form the dominant vein orientation within the Main Zone corridor of the Leprechaun Deposit, providing increased width to the Main Zone corridor and increased continuity the high-grade mineralization extending from surface to the bottom of the open pit and beyond into potential future underground resource development. The current drilling program is designed to both further confirm the geological model for the Leprechaun Deposit and to continue to upgrade Inferred resource material into the Measured and Indicated resource categories.

“The new drill results continue the success we have had with our Leprechaun drilling program. Main Zone (MZ) intersections continued to expand the higher grade mineralization along much of the strike length of the Leprechaun Deposit and drilling from the hanging wall has confirmed mineralization away from the Main Zone that will help to reduce the strip ratio.” said Phillip Walford, President and CEO of Marathon Gold. “The drilling is now complete at Leprechaun and resources estimation for Leprechaun is expected to be complete in September using all the new drill results.”

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

Sherry Dunsworth, M.Sc., P. Geo., Senior VP 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 (70% - 90% of core length).

About Marathon

Marathon is a Toronto based gold company rapidly advancing its 100%-owned Valentine Gold Camp located in Newfoundland and Labrador, one of the top mining jurisdictions in the world. Marathon has confirmed the feasibility of the Valentine Gold Camp, which currently hosts four near-surface NI 43-101 complaint, mainly pit-shell constrained, deposits with measured resources totaling 16.6 million tonnes at a grade of 2.18 g/t containing 1,166,500 oz. of gold, indicated resources totaling 28.5 million tonnes at a grade of 1.66 g/t containing 1,524,900 oz. of gold and inferred resources totaling 26.9 million tonnes at a grade of 1.77 g/t containing 1,531,600 oz. of gold. The majority of the resources occur in the Marathon and Leprechaun deposits, which also have resources below the current open pit shell. Both deposits are open at depth and on strike. Gold mineralization has been traced down almost a kilometer vertically at Marathon and over 350 meters at Leprechaun. The four deposits identified to date occur over a 20-kilometer system of gold bearing veins, with much of the 24,000-hectare property having had only minimal exploration activity to date.

The Valentine Gold Camp is accessible by year-round road and is in close proximity to the provincial electrical grid. Marathon maintains a 50-person all-season camp at the property. Recent metallurgical tests have demonstrated 93% to 98% recoveries via conventional milling and an average of 65 to 72% extraction rates for 23 mm (1/2 inch) material via lower cost heap leaching at the Marathon and Leprechaun Deposits respectively.
