Marathon Gold Intersects Further High-Grade Gold Mineralization at the Leprechaun Gold Deposit and J. Frank Zone, Valentine Lake Project

Highlights include:

Leprechaun Gold Deposit

• Step-out drilling in the northeast area of the deposit intersected multiple high-grade intervals up to 60 meters down-dip from the Main Zone with 9.07 g/t Au over 6.80 meters including 66.63 g/t Au over 0.85 meters (Photo 1) and 7.38 g/t Au over 2.55 meters including 22.05 g/t Au over 0.85 meters in VL-12-414 and 22.05 g/t Au over 2.25 meters including 66.03 g/t Au over 0.75 meters and 15.10 g/t Au over 2.25 meters including 42.45 g/t Au over 0.75 meters in VL-12-409.
  
  
• Step-out drilling in the central area of the Leprechaun Gold Deposit intersected high-grade intervals 40 meters down-dip from the Main Zone with 8.06 g/t Au over 11.4 meters including 29.54 g/t Au over 0.95 meters and 29.64 g/t Au over 0.95 meters in VL-12-410.
  
  
• Significant new near surface high-grade Hanging Wall mineralization include 15.80 g/t Au over 6.0 meters including 65.33 g/t Au over 0.75 meters in VL-12-416 .

J. Frank Zone

• New near surface high-grade Hanging Wall mineralization include 6.46 g/t Au over 3.0 meters including 19.14 g/t Au over 1.0 meters in VL-12-428.
  
  
• New wide intervals of Main Zone style mineralization at the J. Frank Zone include 0.64 g.t Au over 61.75 meters with 12.90 g/t Au over 0.95 meters in VL-12-431.
  
  
• The Leprechaun Gold Deposit continues to demonstrate expansion both down-dip and along strike while the discovery of wide intervals of Main Zone style mineralization at the south west end of the current J. Frank Zone, provides an exciting target for future drilling.

"The Leprechaun Gold Deposit has continued to expand with our highly successful winter 2012 drilling program. The intersection of new wide intervals of Main Zone style mineralization in the J. Frank Zone, confirms the continuity of the gold system operating along the highly prospective thrust fault, which extends for over 25 kilometers within the Valentine Lake property," said Phillip Walford, President and CEO of Marathon Gold. "Summer drilling has resumed and with three drills turning, steady news flow is expected".

The Valentine Lake Project, including the Leprechaun Gold Deposit, is a 50/50 Joint Venture between Marathon and Mountain Lake Resources Inc. Both companies are equal contributors to a planned 40,000 meter 2012 drilling program in which Marathon is the operator.  The 2012 exploration program has started at the Leprechaun Gold Deposit and will continue to expand southwest into the J. Frank Zone and northeast into the Sprite Zone. All grades in this release are uncut, and all thicknesses are estimated true thicknesses. A total of 57 drill holes totaling 15,359 meters (38.4%) of the planned 2012 drilling campaign have now been completed.

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 and Mountain Lake Resources Inc. The Leprechaun Gold Deposit is situated at the south-western end of the Valentine Lake Project, and the Valentine East Gold Zone is located 17 kilometers along strike running in a north-easterly direction.  The J. Frank Zone, which currently extends over an area in excess of 850 meters in length and 250 meters in width, is located up to 0.5 kilometers southwest along strike from the current resource boundary of the Leprechaun Gold Deposit. These gold occurrences form part of a 23 kilometer long, highly prospective gold-bearing mineralized corridor. Marathon is the operator of the Joint Venture, and the companies have agreed to jointly fund the $11.53 million budget in 2012 that includes plans for 40,000 meters of drilling which is currently ongoing.

About the Leprechaun Gold Deposit

The Leprechaun Gold Deposit has a NI 43-101 compliant Measured and Indicated Resource of 6,446,000 tonnes grading 2.05 g/t gold, for a total estimated 424,000 ounces of gold (news release, March 29, 2012). The Inferred Resource is 5,742,000 tonnes grading 1.65 g/t gold, for an estimated 305,000 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.
