Marathon Gold Reports Initial NI 43 101 Resource Estimate for the Golden Chest Mine
TORONTO, March 5, 2012 /CNW/ - Marathon Gold Corporation ('Marathon' or the 'Company')
today announced its first NI 43 101 compliant Resource Estimate for the Golden Chest Mine in north eastern Idaho, USA (Figure 1). The Initial Resource Estimate is an essential component of the projects' development and is a key milestone for Marathon. The Golden Chest Mine is owned 50% by New Jersey Mining Corporation ('NJMC') and 50% by Marathon Gold Corporation and NJMC is the operator.'The successful completion of the Initial Resource Estimate is a great achievement for Marathon. The dedicated crew at New Jersey Mining did a great job in carrying out the 10,000 meter drilling program last year, and most of the results of that drilling have been included in this Resource. There is still open pit potential in the higher grade north end of the Mine and the underground potential has not yet been tested, so we are excited to continue actively drilling this project. The aggressive 20,000 meter 2012 drilling program, which is almost double last year's program, will be focused on expanding the open pit to the north and expanding the underground potential in the high-grade veins,' stated Phillip Walford, President and CEO of Marathon Gold.

1. Resource finding cost of CAD$9.00
2. The 0.4 g/t gold open pit cut-off grade underlying the Resource
Estimate is based on a number of parameters and assumptions
including a gold price of US$1,200 per troy ounce, 92%
metallurgical gold recovery, mining costs of US$2.00/tonne,
process costs of US$9.50/tonne, General & Administrative costs of
US$2.00/tonne and environmental rehabilitation costs of US$0.20
per tonne treated.
3. The quantity and grade of reported Inferred mineral Resources in
this estimation are uncertain in nature and there has been
insufficient exploration to define the Inferred mineral Resources
as Indicated or Measured mineral Resources. It is uncertain if
further exploration will result in upgrading them to Indicated or
Measured mineral Resource categories.
4. The mineral Resources in this news 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. The effective date of
this mineral Resource Estimate is March 2012.
Audited Mineral Resource parameters:
a. Estimations are based on sample composites of 2 meters. Grade
capping was applied to a single sample grading 864 g/t Au.
Based on detailed statistical analysis combined with
information from drill hole logs, no further grade capping was
deemed necessary.
b. A 0.40 g/t Au cut-off grade was applied for the 3D deposit
modeling.
c. A specific gravity of 2.66 tonnes per cubic meter was used.
d. Resources were modeled using 3D interactive modeling backed by
sectional interpretation.
e. The database for the Golden Chest deposit comprised a total of
14,550 meters (113 DDH and 13 RC) of drilling.
f. The mineralized zones at the Golden Chest Mine extend
approximately 920 meters along strike. The Resource has been
constrained by a conceptual open pit shell that includes
Resources to a maximum depth of 250 meters.
g. The grade estimation was done using ordinary kriging
interpolation using 2.0 meter composites. All estimations are
based on a percent block model with unitary dimension of 5
meters East, 5 meters North and 5 meter elevation.
h. Indicated mineral Resources include all mineralized blocks
within half to one time of the variogram range and are
estimated using a minimum of 3 drill holes.
i. Inferred mineral Resources include all mineralized blocks
within one to three times of the variogram range and are
estimated with a minimum of 2 drill holes including the
isolated areas and the blocks that were estimated in the passes
one and two (M&I) that not comprised the criteria of these two
categories.
This Resource has been estimated in compliance with National Instrument 43-101 standards and a corresponding Technical Report will be filed under the Company's profile on SEDAR in the time allotted. The Resource Estimate was completed by Micon International Limited (Micon) using both Ordinary Kriging and Inverse Distance Cubed methods, which gave similar results. The reported figures are taken from the Ordinary Kriging modeling. The Micon staff responsible for this Resource Estimate are Messrs Charley Murahwi, M.Sc., P. Geo., FAusIMM and Alan J. San Martin, MAusIMM(CP), both of whom are Qualified Persons as defined by NI 43-101, and are independent of Marathon Gold Corporation and New Jersey Mining Company. Micon acknowledges that it has read this news release and there are no errors contained herein.
Phillip Walford P.Geo, President and CEO of Marathon Gold, is Marathon's Qualified Person in compliance with National Instrument 43-101 with respect to this release. Mr. Walford has reviewed the contents for accuracy and has approved this new release on behalf of Marathon.
Golden Chest Mine
The Golden Chest Mine is located two miles east of Murray, Idaho within the gold belt of the Coeur d'Alene Mining District. The mine has over 3,900 m of underground workings and has the permits necessary to drill and operate on the deposit. The property includes 24 patented mining claims and 70 unpatented mining claims covering 515 hectares. The patented claims that cover the mine workings have mineral and surface rights enabling the Joint-Venture to work easily on the Mine property.
