Marathon Gold Announces Q2 2018 Financial Results

TORONTO, Aug. 15, 2018 - Marathon Gold Corp. (MOZ-TSX) (“Marathon”) announced today its financial results for the three and six months ended June 30, 2018.

With the completion of the preliminary economic assessment (“PEA”) on the Valentine Lake project, Marathon’s focus with respect to Valentine Lake has progressed toward development as opposed to a pure exploration focus. Marathon completed the following activities in the period ended June 30, 2018, and subsequently to date:

Financing and Liquidity:
At June 30, 2018, Marathon’s cash position was $3.2 million compared to $7.2 million at December 31, 2017. In July 2018, Marathon closed a bought deal prospectus financing of common shares and flow through shares which generated aggregate gross proceeds of $8.1 million and net proceeds of approximately $7.3 million.

Preliminary Economic Assessment:
In May 2018 Marathon completed its initial PEA on the Valentine Lake project, the first economic study undertaken at Valentine Lake. The results of this study were very encouraging and positive, confirming a potential mining operation involving heap leaching and conventional processing, producing 188,500 ounces of gold per year for the first 10 years of its life at an all-in sustaining cost (“AISC”) of US$595 per ounce and generating a pre-tax IRR of 34% and an after-tax IRR of 25% on estimated pre-production costs of US$380 million. The project is anticipated to produce an after-tax NPV (5%) of US$367 million (CAD$466 million) for an 11-year mine life, and the after-tax payback period is 2.8 years.

Mineral Resource Estimate:
As part of the PEA, the resource estimate for the Marathon Deposit was updated in March 2018 to incorporate the results of fire assay and metallic screen assays received to March 2, 2018, and the resources for the Leprechaun and Victory Deposits were updated to apply the design of open pits for these deposits to the underlying resource estimates.

With completion of the March 2018 resource estimate, the Valentine Lake property hosts a total Measured and Indicated resource of 2.1 million ounces of gold at a grade of 1.99 g/t and an additional Inferred resource of 1.1 million ounces at a grade of 1.99 g/t. Between March 2015 and April 2018, the global Measured and Indicated resource increased by 1.1 million ounces or 102%, while the global Inferred resource increased by 0.9 million ounces or 456%.

Drilling:
Drill programs, which ran from January to March and May to November 2017, January to March 2018, and June 2018 to date, focused on:

• expanding and upgrading the Marathon and Leprechaun resources in advance of the May 2018 preliminary economic deposit;
• infill drilling at the Marathon Deposit intended to upgrade inferred resources to the measured and indicated categories and additional drilling in the hanging wall and footwall of the main area of the deposit in an effort to decrease the strip ratio; and
• completing a program of widely spaced exploration holes in the 3.5-kilometer bog zone between the Sprite and Marathon Deposits to determine the potential of this area of the property, which has seen little in the way of exploration activity, to host mineral resources.

Operating Results:
The results of operations for the three- and six-month periods ended June 30, 2018 and 2017 are summarized below.

This press release should be read in conjunction with Marathon's condensed interim consolidated financial statements for the periods ended June 30, 2018 and 2017 and the related Management's Discussion and Analysis, both of which are available on www.sedar.com.
