TORONTO, April 20, 2012 /CNW/ - Marathon Gold Corporation ("Marathon" or the "Company") today announced it has filed its Technical Report with the first NI 43-101 compliant Resource Estimate on the Golden Chest Mine in north eastern Idaho, USA and it can be found on the SEDAR website. The Technical Report was completed by Micon International Limited (Micon) and was released March 5, 2012. The completion of the Technical Report was a milestone for the Company and a significant contributor to the development of the Golden Chest Mine. The Golden Chest Mine is owned 50% by New Jersey Mining Corporation ("NJMC") and 50% by Marathon Gold Corporation and NJMC is the operator. Highlights: -- Global Resource: M&I 3,107,000 tonnes @ 1.47 g/t Au, with 147,000 oz of contained gold, Inferred 4,978,000 tonnes @ 1.46 g/t Au, with 233,300 oz of contained gold -- The Technical Report can be found at www.sedar.com "Marathon is having great success at the Golden Chest Mine. The results of the initial Resource Estimate, which were based on last year's 10,000 m drilling program, confirm that there is significant potential for this to be a sizeable deposit. Since the commencement of this year's 20,000 m drill program, the open pit infill holes have further indicated that the current deposit is expanding and the underground targeted holes are also extending the strike length of the Idaho vein system in an area that has not been previously drilled," said Phillip Walford, President and CEO of Marathon Gold. "As this year's drill program progresses, we are looking forward to drilling the high-grade Katie-Dora area to target the extension of the open pit Resource to the north." Golden Chest Mine Measured and Inferred Initial Resource Indicated Estimate Global Resource Tonnes 3,107,000 4,978,000 Grade (g/t Au) 1.47 1.46 Ounces @ 0.4 g/t cut- 147,000 233,300 off In Open Pit Tonnes 2,788,000 3,847,500 Grade (g/t Au) 1.35 1.45 Ounces @ 0.4 g/t cut- 121,100 179,000 off 1. 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. 2. 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. 3.
