Marathon Deposit Expanding with High-Grade Gold: 5.75 g/t Au over 16.0 meters, 5.30 g/t Au over 16.0 meters and 6.30 g/t Au over 11.0 meters, Valentine Lake Gold Camp, Newfoundland

•October 24, 2018

Highlights:

Drilling

• Drill holes MA-18-327 and MA-18-328 succeeded in extending higher-grade gold intervals further into the southwest end of the Marathon Deposit open pit (Figure 1) with MA-18-328 intersecting 5.75 g/t Au over 16.0 meters and MA-18-327 intersecting 5.65 g/t Au over 13.0 meters.
   
• Infill drill holes MA-18-309, MA-18-319 and MA-18-324 succeeded in extending the main zone mineralization towards the foot wall contact with very good grade intercepts of 1.75 g/t Au over 17.0 meters in MA-18-309,  1.83 g/t Au over 20.0 meters and 6.30 g/t Au over 11.0 meters in MA-18-319 and 5.30 g/t Au over 16.0 meters  in MA-18-324 (Figure 1).
   
• Drill holes MA-18-312, MA-18-313, and MA-18-316, drilled down along the outer hanging wall margin of the Marathon Deposit mineralized corridor, intersected multiple gold-bearing QTP zones to help expand the resource including 2.03 g/t Au over 12.0 meters in MA-18-316,  7.44 g/t Au over 4.0 meters, 5.04 g/t Au over 6.0 meters and 9.44 g/t Au over 3.0 meters in MA-18-313, and 6.54 g/t Au over 3.0 meters and 4.16 g/t Au over 3.0 meters in MA-18-312.

Program Update

• The 2018 step-out and infill drilling program of 41,000 meters will be completed in the next week. The addition of the 3^rd drill during the summer 2018 enabled the program to end a month early. The results from the 2018 drill program will be incorporated into the planning for the winter 2019 drilling program which will focus on expanding open pit resources at the Marathon Deposit and Sprite Zone as well as infill drilling to reduce the amount of inferred resources in the Marathon Deposit pit shell.
   
• The advanced metallurgical testing continues on material from both the Marathon and Leprechaun Deposits, with the aim of optimizing both mill and heap leach recoveries.

TORONTO, Oct. 24, 2018 (GLOBE NEWSWIRE) -- Marathon Gold Corporation (“Marathon” or the “Company”) (MOZ.TO) is pleased to announce our continued drilling success with intersecting multiple intervals of en-echelon stacked QTP veining with moderate and high-grade gold grades at open-pit depths in both the footwall and hanging wall margins of the main mineralized corridor of the Marathon Deposit (Figure 1). The drill holes MA-18-309, MA-18-312, MA-18-313, MA-18-319 and MA-18-324, drilled down along both the footwall and hanging wall margins of the mineralized corridor, effectively widened the mineralized corridor. They will help decrease the strip ratio for the open pit and will contribute to the re-classification of inferred material into the measured and indicated category for the next resource update. The southwest step-out holes MA-18-327 and MA-18-328 confirm the along strike continuation of abundant stacked QTP veining with good gold grades at both shallow and deeper depths in the southwestern end of the current Marathon Deposit open pit shell. Drill holes with assays pending (Figure 1) confirm the presence of shallow dipping, multiple en-echelon stacked QTP-Au veining extending further and deeper along strike to the southwest.

“The continued success in drilling multiple, good gold intercepts along both margins of the mineralized corridor as well as extending excellent gold grades at depth towards the southwestern end of the current resource pit shell is expected to add significantly to the upgrading of the next Marathon resource update,” said Phillip Walford, President and CEO of Marathon Gold. “The current program of delineating additional mineralization to the southwest along strike on the Marathon Deposit has been a success. The mineralization remains open southwest towards the Sprite Deposit and will be a primary focus area for drilling in the new year. We will continue to add new ounces of gold to the global resource, moving inferred material into measured and indicated resource category in advanced of the Pre-Feasibility Study.”

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 (70-95% of core length).

About Marathon

Marathon Gold Corp. is a high-quality growth-oriented gold development company with a long-term strategy of moving the 100% owned Valentine Lake Gold Camp through to production in central Newfoundland. Marathon recently completed a positive PEA that shows an average annual production of 188,500 ounces per year over the first 10 years, payback of 2.8 years, NPV (5%) of $367 million (USD) and an IRR of 25.3%, all after-tax. The Valentine Lake Gold Camp currently hosts four near-surface, mainly pit-shell constrained, deposits with measured and indicated resources totaling 2,137,100 oz. of gold at 1.99 g/t and inferred resources totaling 1,104,800 oz. of gold at 1.99 g/t. Most of the resources occur at the Marathon and Leprechaun Deposits. All the deposits are open to expansion. Marathon’s 240 sq. km sized Valentine Lake property has multiple exploration targets to be explored in 2018.
