An additional 12,128 metres of reverse circulation (RC) drilling was completed at the Leprechaun and Marathon Deposits to provide validation to the Project's mineral reserve block model. The 2021 exploration and RC drilling will be incorporated into an update to the Project's Mineral Resource estimate, scheduled for mid-year 2022;
• During the fourth quarter of 2021, the Company continued permitting, engineering, community engagement, procurement, project financing and team development activities with a view to a potential construction decision for the Project in 2022. At December 31, 2021 the company had 62 employees and 92 dedicated contract personnel, 86% within the province of NL;
  
  
• Subsequent to the year end, on March 16, 2022, the Company was notified that the Impact Assessment Agency of Canada had completed its technical review of the Project's Environmental Impact Statement ("EIS") and would move forward with the completion of an EA Report for public review;
  
• Subsequent to the year end, on March 17, 2022, the Company was notified by the NL Minister of Environment and Climate Change that the Environmental Assessment Committee overseeing the provincial environmental assessment ("EA") of the Project had completed its review of the Project's EIS and, concurrently, Marathon was advised that the Project has received approval by the Cabinet of the Government of Newfoundland and Labrador. This marks the completion of the provincial EA process, allowing Marathon to commence site-specific permitting including the acquisition of the Project's Mining Lease;

• During 2021 Marathon's Board of Directors was strengthened with the appointment of Ms. Cathy Bennett.

Matt Manson, President and CEO commented: "We made steady progress during 2021 on multiple fronts towards the delivery of the Valentine Gold Project as Atlantic Canada's largest gold producer. We delivered a positive Feasibility Study in April and had advanced our engineering, design and procurement work significantly by year end. We have continued to strengthen our project team and build-out our staffing in the central region of Newfoundland around our Grand Falls-Windsor base. Community cooperation agreements with six central region communities were solidified and we entered into engagement agreements with both the Qalipu and Miawpukek Mi'kmaq First Nations. Subsequent to the year end, in March, we were very happy to see our hard work in social and environmental assessment culminate in release from the provincial EA process and completion of the federal EIS review. Concurrently with these project development efforts, we were also able to report consistently good results in our exploration efforts, with a continuing focus on the new Berry Deposit. With a strong cash balance of $87 million at year end, we are well placed to deliver the next milestones in project delivery during 2022."

Financial Performance

The results of operations for the fourth quarter of 2021 are summarized below (all figures are in Canadian dollars unless otherwise noted):

Three months ended December 31, 2021:

• General and administrative expenses increased from $2.83 million to $2.92 million. The principal components of this increase are set out below:
  
  
  • Project Financing advisory & professional fees increased from $nil to $1.00 million, resulting from advisory, legal, and due diligence related costs, as the Company commenced the process of assessing project financing alternatives in the first quarter of 2021.
  • Investor relations and corporate communications expenses increased from $0.02 million to $0.12 million, reflecting a shift from virtual to in-person investor and corporate communications, including engagement with stakeholders in the local communities around the Valentine Gold Project and in-person analyst and investor site tours, as COVID-19 restrictions within NL were lifted.
  • Share-based compensation expense decreased from $1.08 million to $0.61 million, due to a $0.40 million decrease in Deferred Share Unit expense as the increase in the Company's share price in the three months ending December 31, 2021 was lower than the same period in 2020 and a $0.15 million decrease in stock option expense as there were less initial option grants in the three months ending December 31, 2021 compared to the same period in 2020, offset partially by a $0.08 million increase in restricted share unit ("RSU") expense related to vesting of RSUs granted in 2021.

• Salaries and wages decreased from $1.08 million to $0.72 million, due to higher capitalized salaries and wages compared to the same period in the prior year, offset partially by an increase in overall compensation costs as a result of the additions made to the Company's management team throughout 2021. For additional details regarding the changes to the Company's management team during the quarter, see the "Corporate Developments" section below.
  
  
• Professional fees decreased from $0.42 million to $0.20 million, due primarily to a reclassification of consulting fees to project financing advisory & professional fees expense.
  

• Finance income, net decreased from $0.19 million to $0.15 million, primarily as a result of a decrease in interest income from $0.18 million to $0.12 million, due to a decrease in interest earned on term deposits offset partially by an increase in interest earned on higher overall cash balances compared to the same period in 2020.
• Deferred income tax (recovery)/expense increased from an expense of $0.30 million to a recovery of $0.35 million, primarily due to a larger increase in non-capital loss carry forwards compared to the same period in 2020.
• Capital expenditures excluding working capital movements, were $9.94 million higher than the prior year primarily as a result of project construction capital spending commencing in the third quarter of 2021, including increased detailed engineering, procurement of a permanent camp and further contribution payments associated with the construction of the powerline by NL Hydro. In addition, there was increased exploration drilling completed compared to the prior year resulting from increased Victory Deposit drilling, in support of further resource growth.

Twelve months ended December 31, 2021:

• General and administrative expenses increased from $7.60 million to $9.70 million. The principal components of this increase are set out below:
  
  
  • Project Financing advisory & professional fees increased from $nil to $2.67 million, resulting from advisory, legal, and due diligence related costs, as the Company commenced the process of assessing project financing alternatives in the first quarter of 2021.
  • Salaries, wages, and benefits expenses decreased from $3.00 million to $2.71 million, due to higher capitalized salaries and wages compared to the same period in the prior year, offset partially by an increase in overall compensation costs as a result of the additions made to the Company's management team throughout 2021. For additional details regarding the changes to the Company's management team during the quarter, see the "Corporate Developments" section below.

• Investor relations and corporate communication expenses decreased from $0.41 million to $0.31 million, resulting primarily from a decrease in corporate promotional items expenditures and corporate communication consulting fees compared to the same period in the prior year.

• Finance income, net decreased from $0.37 million to $0.25 million, primarily as a result of a $0.08 million increase in other finance expense, as a portion of the share issuance costs related to the May 2021 private placement financing were allocated to the flow-through share tax liability, and a decrease of $0.04 million in interest income due to a decrease in interest earned on term deposits.
• Deferred income tax (recovery)/expense increased from $0.05 million to $2.21 million, mainly due to management's reassessment of the temporary difference associated with Mineral Exploration and Evaluation assets in the third quarter of 2021.
• Capital expenditures, excluding working capital movements, were $22.70 million higher than the prior year primarily as a result of project construction capital spending commencing in the third quarter of 2021, including increased detailed engineering, procurement of a permanent camp and further contribution payments associated with the construction of the powerline by NL Hydro. In addition, there was increased exploration drilling completed compared to the prior year resulting from increased Berry Deposit drilling, in support of further delineation of the ore body and resource growth.
