TORONTO, ON--(Marketwired - May 31, 2017) - Marathon Gold Corporation ("Marathon" or the "Company") (MOZ.TO) is excited to announce the Company's plans for exploration and development activities at the Valentine Lake Gold Camp following the recent closing of the bought deal financing which generated gross proceeds of $18.6 million. The net proceeds of the offering will allow Marathon to continue infill, extension and exploration drilling at the Valentine Lake Gold Camp, advance the metallurgical programs, and increase the ongoing environmental work at the property in preparation for future mine permitting, among other activities as set out in additional detail within the final short form prospectus of the Company dated May 16, 2017. Marathon has increased staff and expanded facilities at the Valentine camp as we commence our expanded exploration program.

Highlights of New Program:

• 60,000-meter drill program focused primarily on the Marathon Deposit
• Three drills on site, with a fourth to be added in the third quarter of 2017
• Prospecting a 7-kilometer area to the northeast of the Victory Deposit, where historical gold showings warrant additional work
• Advanced environmental studies for future mine permitting
• Additional metallurgical work to optimize recoveries for conventional milling and heap leaching
• Updated property wide resource update expected in Q3 2017 followed by a PEA in Q4 2017

"We now have the financial capacity needed to move the Valentine Lake Gold Camp to the next level including an expanded drill campaign, continued exploration of deeper mineralization and prospecting work throughout the entire property," commented Phillip Walford, President and CEO of Marathon. "We plan to complete a 60,000 meter drill campaign at the Valentine Lake Gold Camp which will allow us to expand the Marathon Deposit along strike to the southwest and to depth. This is going to be a very busy year for us as we look to significantly expand the property wide resource."

The company is also happy to announce the following new drill results from the Marathon Deposit at the Valentine Lake Gold Camp:

• Drill hole MA-17-176 intersected 118 meters grading 1.56 g/t Au including higher grade intervals of 22 meters grading 3.58 g/t Au and some narrower high grade intercepts as well. Deeper in the hole a 15 meter intersection grading 2.73 g/t Au contained 4 meters of 7.28 g/t Au.
• Drill hole MA-17-177 intersected the mineralized corridor as planned at 190 meters and intersected numerous small zones with good grades including 7 meters grading 4.82 g/t Au and 2 meters grading 11.11 g/t Au.
• Drill hole MA-17-178 intersected the mineralized corridor at 200 meters and encountered 89 meters grading 1.84 g/t. This intersection has several intervals of good grade including 4 meters of 14.1 g/t and 9 meters of 5.07 g/t Au. This hole is still in progress with the last reportable intersection from 531-534 meters grading 10.03 g/t Au.

Quality Assurance-Quality Control ("QA/QC")

Sherry Dunsworth, M.Sc., P. Geo., SVP 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 (80% to 95% of core length).

About Marathon

Marathon is a Toronto based gold exploration company rapidly advancing its 100% owned Valentine Lake Gold Property located in Newfoundland, one of the top mining jurisdictions in the world. The Valentine Lake Gold Property currently hosts four near-surface, mainly pit-shell constrained, deposits with measured and indicated resources totaling 1,388,200 oz. of gold at 1.91 g/t and inferred resources totaling 766,500 oz. of gold at 2.24 g/t. The majority of the resources occur in the Marathon and Leprechaun deposits, which also have resources below the pit shell. Both deposits are open to depth and on strike. Gold mineralization has been traced down over 350 metres vertically at Leprechaun and almost a kilometer at Marathon. The four deposits outlined to date occur over a 20-kilometer system of gold bearing veins, with much of the 24,000-hectare property having had little detailed exploration activity to date. Drilling in 2017 is continuing to focus on expanding the Marathon Deposit at surface and to depth.

The Valentine Lake Gold Property is accessible by year-round roads and is located in close proximity to Newfoundland's 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 50% to 70% recoveries via low cost heap leaching at both the Leprechaun and Marathon Deposits.
