Marathon Gold Announces Updated Resource Estimate and 25,000 m Drill Campaign

TORONTO, Dec. 16 /CNW/ - Marathon Gold Corporation (MOZ-TSX) ("Marathon") today announced the completion of an updated National Instrument (NI) 43-101 compliant resource estimate for the Leprechaun Gold Deposit, which is situated within the Valentine Lake Gold Project in central Newfoundland.  This is the first Measured and Indicated ("M+I) resource that has been developed within the Valentine Lake Gold Project ("Valentine Lake") and is a major advance for the project.

Additionally, Marathon would like to announce that a fully funded 25,000 metre drill program will start in January.  The program will include aggressive resource expansion and exploration drilling to further evaluate the Property's potential.


  • strike length of resource is now 750 m with an additional 750 m of gold mineralization
  • new resource is open down-dip and along strike to the southwest and northeast
  • 74% of the M+I ounces and 73% of the tonnes are within 150 m of surface where the new 2010 drill holes are concentrated
  • planned 25,000 m drill campaign with two drill rigs to start in January
  • drilling to commence in January on the northeast arm of the Leprechaun Deposit, Sprite Prospect and Valentine East Deposit
  • plans for 2011 include further metallurgical testing, drilling of geotechnical holes to assess the competency of potential pit walls so that a preliminary economic assessment can be completed by the 1st quarter of 2012,  base line environmental studies will also commence

Phillip Walford, President and CEO of Marathon commented, "The results demonstrate clearly that there is open pit potential at the Leprechaun deposit.  Both Marathon Gold and Mountain Lake believe that the geological model developed is working well and indicating where additional resources can be found. We are now poised to rapidly develop resources with what will be the largest drilling campaign to date on the property."

(1) 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, taxation, sociopolitical, marketing, or other relevant issues.
(2) The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.

Resource Model

In order to better represent the geology of the Leprechaun Gold deposit, a block model was constructed which used an unfolding technique on the sample search ellipsoid.  This approach allows a search ellipsoid to better reflect the actual trend of the mineralization.  In addition, smaller block sizes were used in the mineralized zones to further help delineate the overall potential resource. Most of the previous drill holes were not completely sampled in all the mineralized zones and that has had a negative effect on the resource. Any unsampled intervals were considered as having a gold assay of 0.0 g/t.  All of the new drill holes from this year were sampled in for every interval down the hole. Grade estimates were run using kriging, inverse distance squared, and polygonal and all compared favorably with each other.  For the reported resources, the kriged gold estimate was used.  High grade gold outlier values (76 g/t or higher) were given a limited area of influence. All of the geologic modeling and resource estimation were completed using the Vulcan mine planning software package.  Details of the resource estimation will be available in an NI 43-101 compliant resource report to be filed within 45 days of this press release.

The mineral resources in this press release 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 December 11, 2005.

The Valentine Lake Project is an option and joint venture agreement with Marathon Gold Corporation and Mountain Lake Resources.  Marathon is the operator. The two companies are pleased with the advancement of the property over the last year and have agreed to an aggressive exploration and resource definition drilling program of 25,000 m in 2011 to more fully evaluate the property's potential. This program will begin in January with two drills on site. Drilling will be concentrated on developing and expanding the Leprechaun Deposit resources as well as the nearby Sprite Zone 800 m along strike from Leprechaun. IP surveys over both zones indicate that the mineralization extends below 400 m in depth. Some holes will test these deeper geophysical targets for underground resource potential. The Valentine East Zone, 13 km along strike from the Leprechaun Deposit, will be drilled as well to test the mineralization intersected in historic drill holes of up to one gram over 60 m near surface.

Qualified Person

The mineral resource estimate was prepared by Sam Shoemaker, MAusIMM, of Micon International, and is the independent qualified person (QP) for the mineral resource estimate.  Sherry Dunsworth, M.Sc., P. Geo., VP of Exploration, is Marathon's Qualified Person in compliance with National Instrument 43-101 with respect to this release.  Mrs. Dunsworth has reviewed the contents for accuracy and has approved this press release on behalf of Marathon.
