Marathon Gold Reports Positive Drill Results from Sprite Zone, Valentine Gold Project

TORONTO, Dec. 18, 2019 - Marathon Gold Corp. (“Marathon” or the “Company”) (TSX: MOZ) is pleased to report new drill results from the 2019 Sprite Zone exploration program at the Valentine Gold Project in central Newfoundland. These latest results represent fire assay data from 40 out of a total of 46 drill holes located along an approximately 3 km strike length of the Sprite Zone, located 3-5 km northeast of the project’s Leprechaun Deposit (Figure 1). Highlights include:

• VL-19-786 intersected 7.60 g/t Au over 22.0 metres;
• VL-19-776 intersected 10.43 g/t Au over 5.0 metres, and 4.80 g/t Au over 6.0 metres;
• VL-19-780 intersected 7.25 g/t Au over 10.0 metres;
• VL-19-769 returned multiple intersections of 1.63 g/t Au over 16.0 metres, 2.04 g/t Au over 9.0 metres, 4.33 g/t Au over 9.0 metres, 7.53 g/t Au over 5.0 metres, and 2.30 g/t Au over 15.0 metres;
• VL-19-779 returned multiple intersections of 3.82 g/t Au over 13.0 metres, 5.54 g/t Au over 11.0 metres, and 4.30 g/t Au over 5.0 metres;
• VL-19-778 intersected 9.74 g/t Au over 6.0 metres, and 4.73 g/t Au over 5.0 metres; and,
• VL-19-777 intersected 1.54 g/t Au over 16.0 metres.

All quoted intersections comprise uncut gold assays in core lengths. All significant assay intervals are reported in Table 1.

Matt Manson, President & CEO commented: “We are encouraged by these exploration results from an area of the Sprite Zone that was last explored with drilling in 2014 and 2018. The new drill holes were designed to step out from areas of previously identified mineralisation. About half hit new mineralisation, some significantly so. Of note, the drilling has confirmed a new “Main Zone” type sequence of stacked, en-echelon quartz-tourmaline-pyrite veining with significant gold grades at Section 13410E (Figure 2). This new zone is located proximal to the Valentine Lake Shear Zone, extends to a depth of at least 250 metres with an apparent thickness of up to 50 metres, and is bounded by mafic dikes. This is similar to the geological setting of the Main Zones of both the Leprechaun and Marathon Deposits. Hole VL-19-786, which returned 7.60 g/t over 22 metres, represents a 300 metre step-out to the northeast, suggesting potential extension of the mineralisation along strike. We expect that Sprite, and this new discovery area in particular, will be a priority for follow up drilling in our 2020 exploration program.”

The “Sprite Zone” constitutes a broad area of previously identified Quartz-Tourmaline-Pyrite-Au (“QTP-Au”) veining extending northeast of the project’s Leprechaun Deposit and southwest of the Marathon Deposit. Previous drilling in the area identified a modest estimate of Measured and Indicated Mineral Resources of 0.04 Moz (0.72 Mt at 1.17 g/t) and Inferred Mineral Resources of 0.09 Moz (2.05 Mt at 1.40 g/t) in several small and shallow pit shell settings (Figure 1). Mining in these Sprite Zone pit areas was not contemplated in the October 2018 Preliminary Economic Assessment and is not expected to be included in the upcoming Pre-Feasibility Study.

Twenty of the forty exploration drill holes reported today returned no significant intervals of mineralisation. These represent drilling in step-out areas showing no developed QTP-Au veining, drill holes extending northwestwards into the hanging-wall and away from previously identified mineralisation closer to the Valentine Lake Shear Zone, or lateral step-out holes within the hanging-wall adjacent to previously identified areas of mineralisation. Results from the remaining six 2019 Sprite drill holes remain outstanding.

Quality Assurance-Quality Control (“QA/QC”)

QA/QC protocols followed at the Valentine Gold Project include 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 0.30 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 is a Toronto based gold company rapidly advancing its 100%-owned Valentine Gold Project located in central Newfoundland, one of the top mining jurisdictions in the world. The Valentine Gold Project comprises a series of mineralised deposits along a 20-kilometre system of gold bearing Quartz-Tourmaline-Pyrite veins. The project is accessible by year-round road and is in close proximity to the provincial electrical grid. To date, four gold deposits at Valentine have been delineated, including the large Leprechaun and Marathon deposits. An October 2018 Preliminary Economic Assessment showed the project to be amenable to open pit mining and conventional milling over a twelve-year mine life. Total Mineral Resources currently comprise Measured Mineral Resources of 16.6 million tonnes at a grade of 2.18 g/t containing 1,166,500 oz. of gold, Indicated Mineral Resources of 28.5 million tonnes at a grade of 1.66 g/t containing 1,524,900 oz. of gold and Inferred Mineral Resources of 26.9 million tonnes at a grade of 1.77 g/t containing 1,531,600 oz. of gold. For more information, readers are referred to the technical report prepared in accordance with the requirements of NI 43-101 dated October 30, 2018 for further details and assumptions relating to the project.

In respect of the forward-looking statements and information concerning the interpretation of exploration results and the impact on the project’s mineral resource estimate, Marathon has provided such statements and information in reliance on certain assumptions it believes are reasonable at this time, including assumptions as to the continuity of mineralisation between drill holes. A mineral resource that is classified as "inferred" or "indicated" has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category of mineral resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into proven and probable mineral reserves.

By its nature, this information is subject to inherent risks and uncertainties that may be general or specific and which give rise to the possibility that expectations, forecasts, predictions, projections or conclusions will not prove to be accurate, that assumptions may not be correct and that objectives, strategic goals and priorities will not be achieved. Factors that could cause future results or events to differ materially from current expectations expressed or implied by the forward-looking statements include the ability of the current exploration program to identify and expand mineral resources, operational risks in exploration and development for gold, delays or changes in plans with respect to exploration or development projects or capital expenditures, uncertainty as to calculation of mineral resources, changes in commodity and power prices, changes in interest and currency exchange rates, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral resources), changes in development or mining plans due to changes in logistical, technical or other factors, cost escalation, changes in general economic conditions or conditions in the financial markets. delays and other risks described in Marathon’s documents filed with Canadian securities regulatory authorities.
