Marathon Gold Files 43-101 Technical Report for Updated Resources at the Valentine Lake Gold Camp: 1.4 million oz. (M&I) at 1.91 g/t Au and 766,500 oz. (Inferred) at 2.24 g/t Au

TORONTO, ON–(Marketwired – March 28, 2017) – Marathon Gold Corporation (“Marathon” or the “Company”) (TSX: MOZ) today announced that it has made the regulatory filing of the report entitled “Technical Report on the Mineral Resource Estimate of the Valentine Lake Project.” The updated resource was announced on February 21, 2017 and completed by Micon International Limited (“Micon”).

“The increase in resources is driven almost entirely from drilling at the Marathon Deposit since April 2015. The total resource for the Marathon Deposit of 483,800 oz. grading 1.72 g/t measured and indicated and 583,400 oz. grading 2.20 g/t was accomplished with less than 41,000 m of diamond drilling. The scale of the mineralization is such that resources can be gained quickly and efficiently by drilling,” said Phillip Walford, President and CEO of Marathon.

Highlights of the Resource:

  • Measured & indicated resources have increased by 31% while Inferred resources have increased by 284% for the Valentine Lake Property.
  • Almost all the increase in resources is from the growth of the Marathon Deposit
  • All of the new open pit resources are in the 2 g/t Au range at the Valentine Lake Gold Camp.
  • The In Pit resources represent 93% of the Measured and Indicated resources
  • The underground resources at the Marathon Deposit are the largest on the property.
  • The sub-vertical mineralized corridor of the Marathon Deposit has a current drilled strike length of over 400 meters, extends to depth for more than 500 meters, and is open in all directions.
  • All four of the known gold deposits at the Valentine Lake Gold Camp are open along strike and to depth.
  • Two drills are currently drilling infill and exploration holes at the Marathon Deposit and will continue until spring thaw makes this drilling too difficult.

About Marathon Gold Corporation

Marathon is a gold exploration company rapidly advancing its 100% owned Valentine Lake Gold Camp located in Newfoundland, one of the top mining jurisdictions in the world. The Valentine Lake Gold Camp currently hosts four near-surface, mainly pit-shell constrained, gold resources totaling 1,388,200 oz. gold at 1.91 g/t (Measured & Indicated) and 766,500 oz. gold at 2.24 g/t (Inferred) (February 2017). These resources occur over a 20-km system of gold bearing veins. Much of the 24,000-hectare property has not been explored in detail to date. Drilling in 2017 will continue to focus on expanding the Marathon Deposit at surface and to depth. The property is accessible by a year-round road and is located near Newfoundland’s electrical grid. The Company has constructed and 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.
