TORONTO, Aug. 25, 2011 /CNW/ - Marathon Gold Corporation ("Marathon" or the "Company") (MOZ:TSX) is pleased to announce the discovery while trenching of a new quartz-tourmaline-pyrite vein structure that extends over a 80 meters strike length in an area 1 kilometer southwest from the southern end of the current Leprechaun Gold Deposit resource boundary [ (Figure 1) ]. Numerous grab samples consisting of quartz-tourmaline-pyrite with coarse visible gold [ (Plate 1) ] returned assays of up to 113.30 g/t Au, 28.01 g/t Au, and 15.33 g/t Au.

The high grade gold samples were collected from frost-heaved angular sub-crop located directly overlying and in contact with the newly uncovered quartz-tourmaline-pyrite-gold vein structure [ (Plate 2) ]. This new gold-bearing vein is part of a larger gold-bearing quartz vein alteration system that currently extends over an area 600 long by 200m wide and is located up to 1.4km southwest along strike from the current resource boundary of the Leprechaun Gold deposit. Additional high-grade gold grab samples have been collected throughout the area. Historical trenching and drilling did not intersect the new vein nor adequately test other mineralization in the area. We plan to drill the area during this fall.

"I have just visited the new vein discovery and observed the visible gold. The alteration, mineralization and vein structure in this new exposure is clearly part of the gold system that currently includes the Leprechaun Gold Deposit located 1 kilometer along strike to the northeast", said Phill Walford, President and CEO for Marathon Gold Corporation. "I am also very encouraged by the additional high grade grab samples occurring within 400 meters to the southwest of the new mineralized vein."

Highlights:

• High grade grab samples consisting of quartz-tourmaline-pyrite with coarse visible gold returned assays of up to 113.30 g/t Au, 28.01 g/t Au, and 15.33 g/t Au.
  
  
• The quartz-tourmaline-pyrite-gold veining and alteration system extends over an area at least 600m by 200m in size, up to 1.4 km along strike to the SW of the current Leprechaun God Deposit resource boundary, and proximal to the Valentine Lake intrusive structurally controlled contact with the Rogerson Lake conglomerate.
  
  
• Ongoing prospecting and stripping continues to exposes additional quartz veining along strike.
  
  
• Channel sampling continues in the SW Leprechaun area; assays pending.

TABLE 1: Significant Assays from Grab Samples - SW of Leprechaun Gold Deposit

All of the samples were analyzed at Eastern Analytical Laboratory Ltd., in Springdale, Newfoundland. Samples were assayed using lead collection fire assay with AA (atomic absorption) finish. Due to the coarse nature of the gold at the Leprechaun Gold Deposit, the metallic screening method is used on economically important intersections using standard fire assay techniques. The reported values in this release are fire assay results.

About the Valentine Lake Joint Venture
The Valentine Lake Joint Venture is a 50/50 joint venture between Marathon Gold and Mountain Lake. The Leprechaun Gold Deposit is situated at the south-western end of the Valentine Lake Project, and the Valentine East Gold Zone is located 13 km along strike running in a north-easterly direction.  These gold occurrences form part of a 23 km long, highly prospective gold-bearing mineralized corridor. Marathon is the operator of the Joint Venture, and the companies have agreed to jointly fund a $6 million budget in 2011 that includes a planned 25,000 meters of drilling.

Leprechaun Gold Deposit
The Leprechaun Gold Deposit has a (news release, [ December 16, 2010 ]) NI 43-101 compliant Measured and Indicated Resource of 3,284,000 tonnes grading 2.62 g/t gold for a total estimated 277,000 ounces of gold. The inferred mineral resource is 4,409,000 tonnes grading 2.01 g/t gold for an estimated 285,000 ounces of gold.  This resource was estimated using a 0.5 g/t gold minimum cut-off over a 3 meter minimum width. The Leprechaun Gold Deposit is open at depth and along strike with 74% of the current Measured and Indicated ounces occurring within 150m of surface.
