Marathon Increases Overall Gold Resource to 1,847,000 ounces M&I at 1.88 g/t gold and 1,012,000 ounces Inferred at 1.65 g/t gold at the Valentine Lake Gold Camp, Newfoundland
TORONTO, Nov. 30, 2017 (GLOBE NEWSWIRE) -- Marathon Gold Corporation (“Marathon” or the “Company”) (TSX:MOZ) has established a new Mineral Resource Estimate for its 100% owned Valentine Lake Property prepared under the direction of John T. Boyd Company in accordance with National Instrument 43-101 (“NI 43-101”).
Highlights:
- Overall Measured & Indicated resource increased by 33% from to 1,847,000 oz. of gold
- Overall Inferred resource increased by 32% to 1,012,000 oz. of gold
- 88% of the Measured and Indicated resource is pit shell constrained
- Marathon’s recently purchase of the underlying NSR will have a positive impact on the Preliminary Economic Assessment (PEA) scheduled for completion in Q2 2018
- Three drills resume further resource expansion in January 2018
“Valentine Lake now hosts the largest gold resource in Atlantic Canada. The most dramatic increase in resources is within the Marathon Deposit which has expanded to the southwest near surface and to depths of 1 kilometer and is still open. Overall, the open pit grades for all of the gold deposits remain in the 2gram gold range and the underground resource at the Marathon Deposit has increased in grade and size. All the deposits remain open in one or more directions. In 2018 Marathon Gold will resume its aggressive drilling program to explore for new deposits along the 30km gold trend it controls and to expand the known deposits,” said Phillip Walford President and CEO of Marathon.

The effective date for the mineral resource estimate is November 27, 2017
Prepared under the direction of John T. Boyd Company
Notes:
1. The effective date for this mineral resource estimate is November 27, 2017 and are reported on a 100% ownership basis.
2. Mineral Resources are calculated at a gold price of US$1,250 per troy ounce.
3. The mineral resources presented above are global and do not include a detailed pit or underground design, only an economic pit shell was used to determine the in-pit mineral resources. The underground mineral resources are that material outside of the in-pit mineral resources above the stated underground cut-off grade.
4. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues
5. The mineral resources presented here were estimated with a block size of 6 m by 6 m by 6 m sub-blocked to a minimum block size of 2 m by 2 m by 2 m using ID3 methods for grade estimation. All mineral resources are reported using an open pit gold cut-off of 0.290 g/t Au and an underground gold cut-off of 1.489 g/t Au. Material between a 0.290 Au g/t value and 0.628 Au g/t is assumed to be processed on a heap leach. Material above a 0.628 Au g/t is assumed to be processed in a mill. Higher gold grades were given a limited area of influence and was applied during grade estimation by mineralized domain.
6. The mineral resources presented here were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council May 10, 2014.
7. Figures are rounded and totals may not add correctly.
Qualified Persons
The Valentine Lake Property is under the direct supervision of Ms Sherry Dunsworth, P.Geo., Senior Vice President of Exploration for Marathon Gold Corporation. Ms Sherry Dunsworth is defined as a Qualified Person as defined by the National Instrument 43-101. Robert J. Farmer, P. Eng. of John T. Boyd Company is responsible for the completion of the resource update and is an independent Qualified Person as defined by the National Instrument 43-101.
Quality Assurance-Quality Control (“QA/QC”)
Thorough QA/QC protocols are followed on the project including the insertion of blanks and standard samples in all drill holes. The core is cut in half and one half retained at site, the other half is tagged and bagged and sent directly to Eastern Analytical Ltd. In Springdale, Newfoundland. Eastern Analytical prepares the samples and uses fire assay with an atomic absorption finish to determine the gold content. All samples above 0.10 grams per tonne in economically interesting intervals are further assayed using metallic screen to mitigate the presence of coarse gold.
About Marathon Gold Corporation
Marathon is a Toronto based 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, deposits with measured and indicated resources totaling 1,847,000 oz. of gold at 1.88 g/t and inferred resources totaling 1,012,000 oz. of gold at 1.65 g/t. The majority of the resources occur in the Marathon and Leprechaun deposits, which also have resources below the pit shell. Both deposits are open to depth and on strike. Gold mineralization has been traced down over 350 metres vertically at Leprechaun and almost a kilometer at Marathon. The four deposits outlined to date occur in a 30-kilometer gold trend on the property, with much of the 24,000-hectare property having had little detailed exploration activity to date.
The Valentine Lake Gold Camp is accessible by year-round roads and is located in close proximity to Newfoundland’s electrical grid. Marathon 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 73% recoveries via low cost heap leaching at both the Leprechaun and Marathon Deposits.
