Marathon Gold Announces 2020 Fourth Quarter and Year-End Results

TORONTO, March 25, 2021 - Marathon Gold Corp. ("Marathon" or the "Company"; TSX: MOZ) today announces its financial results for the fourth quarter and year ending December 31, 2020 and provides an update on the Company's activities at the Valentine Gold Project (the "Project") in Central Newfoundland.

Fourth Quarter Highlights

• Advanced the Feasibility Study ("FS") for the Project with lead consultant Ausenco Engineering Canada Inc. The FS is expected to be completed on schedule prior to the end of the first quarter of 2021;
• Received confirmation that the Environmental Impact Statement ("EIS") for the Valentine Gold Project has been assessed to be in conformance with guidelines issued by the Impact Assessment Agency of Canada in July 2019 and, accordingly, had been accepted into formal federal and provincial technical review processes. These reviews are expected to occur over a period of approximately 12 months and include information requests and submittals, as well as public consultations;
• Continued infill drilling at the newly discovered Berry Zone, with an additional 14,056 metres of drilling over 67 holes completed in the quarter, and continuing to delineate an important new area of gold mineralization at the Project. The Berry Zone drilling program concluded on November 20, 2020 with a total of 31,722 metres drilled in 2020 in support of a first Mineral Resource estimate, currently under preparation. Overall, 50,726 metres of exploration drilling was completed at the Project in 2020;
• Completed a strategic flow-through financing with net proceeds of $8.7 million resulting in cash and cash equivalents of $51.7 million at December 31, 2020;
• Subsequent to the end of the quarter, released details regarding Marathon's 2021 Exploration Program comprising 52,000 metres of drilling at a budget of $10.5 million; and
• Subsequent to the end of the quarter, announced the appointment of Cathy Bennett to the Company's Board of Directors.

Matt Manson, President and CEO commented: "Our objective in 2020 was to advance the Valentine Gold Project in each of the three areas of engineering studies and mine design, environmental assessment, and exploration. Significant progress was made in each area. We will shortly release the results of the Project's Feasibility Study, our environmental assessment is progressing on schedule through technical review and public consultation, and the first mineral resource estimate on the newly discovered Berry Zone is currently under preparation and expected to be completed soon. In 2020 we also continued to strengthen our management team with several key hires, and we announced the appointments of Jim Gowans and Cathy Bennett to our Board of Directors. With an ending cash balance of $52 million, we are well positioned in 2021 to complete the ongoing engineering, permitting, and project financing activities prior to a potential project construction decision. At the same time, we will continue to remain focused on exploration. Whereas our 2020 exploration work was discovery oriented, our 2021 exploration program is designed to add ounces, with 52,000 metres and $10.5 million committed to a combination of infill drilling at Berry, a return to the Sprite and Victory Deposits, and additional generative projects."

Financial Performance

The results of operations for the fourth quarter are summarized below (all figures are in Canadian dollars unless otherwise noted):

Three months ended December 31, 2020:

• General and administrative expenses increased from $1.77 million to $2.83 million. The principal components of this increase are set out below:
  
  
  • Salaries and wages increased from $0.64 million to $1.08 million, reflecting higher overall compensation costs as a result of the additions made to the Company's management team throughout 2020 and higher 2020 bonus expense compared to 2019, offset partially by higher capitalized salaries and wages in the period.
  • Share-based compensation expense increased from $0.74 million to $1.08 million in the quarter, resulting primarily from a $0.81 million increase in the deferred share unit ("DSU") liability resulting from the increase in the Company's share price between the end of the third and fourth quarter of 2020, as compared to a $0.43 million increase in the DSU liability in the same period in 2019.
  • Professional fees increased from $0.13 million to $0.42 million reflecting costs for executive recruitment in connection with the appointment of a new Director, the completion of a benchmarking study for management and director compensation, and increased legal and consulting fees related to the Company's evaluation of project financing alternatives.
  • Investor relations and corporate communications expenses decreased from $0.16 million to $0.02 million, reflecting a shift from in person to virtual investor and corporate communications, including engagement with stakeholders in the local communities around the Valentine Gold Project, due to COVID-19.
• Finance income, net increased from $0.16 million to $0.19 million, primarily as a result of an increase in interest income from $0.15 million to $0.18 million, as Marathon invested surplus cash from the May 2020 equity financing in interest-bearing deposits.
• Other (income)/expense increased from an expense of $0.83 million to income of $0.06 million, primarily as a result of a $0.88 million decrease in severance expense, as there were no executive management changes in the fourth quarter of 2020. Royalty income from the Golden Chest Mine, where the Company holds a 2% net smelter returns royalty, was consistent with the comparable period in 2019.
• Capital expenditures excluding working capital movements, were $1.57 million higher than the prior year primarily as a result of increased activities in the fourth quarter of 2020 related to the advancement of the FS. During the fourth quarter of 2020, exploration drilling continued to be the largest capital expenditure of the Company as Marathon worked to complete its 2020 exploration drill program.

Twelve months ended December 31, 2020:

• General and administrative expenses increased from $3.85 million to $7.60 million. The principal components of this increase are set out below:
  
  
  • Salaries and wages increased from $1.30 million to $3.00 million, reflecting higher overall compensation costs as a result of the additions made to the Company's management team in the second half of 2019 and throughout 2020 and higher bonus expense in 2020 compared to 2019, offset partially by higher salaries and wages capitalized in the year. In addition, there was $0.50 million severance costs recorded to general and administrative expenses during 2020 compared to $nil in the comparable period in 2019.
  • Share-based compensation expense increased from $1.20 million to $2.50 million, primarily as a result of a $0.83 million increase in the DSU liability resulting from an additional 330,000 DSUs being granted during the year and an increase in the Company's share price in the twelve months ended December 31, 2020. In addition, there was an increase of $0.46 million in stock option expense, related to vesting of options on completion of the Pre-Feasibility Study as well as 2020 annual employee option grants. A total of 4,675,000 options were granted in the twelve months ended December 31, 2020.
  • Professional fees increased from $0.57 million to $0.82 million, reflecting costs for executive recruitment in connection with the appointment of a new Director and two senior technical roles, increased legal and consulting fees related to the Company's evaluation of project financing alternatives, increased legal and proxy solicitation costs associated with the Company hosting a virtual Annual and Special Meeting of shareholders in August 2020, and a general increase in legal and consulting fees, as the Company's breadth of corporate activities has grown.
  • Investor relations and corporate communication expenses increased from $0.28 million to $0.41 million, reflecting increased investor and corporate communication initiatives, including engagement with stakeholders in the local communities around the Valentine Gold Project, and the Company hosting a virtual Annual and Special Meeting of shareholders in August 2020.
