Marathon Gold Discovers New High-Grade Gold Quartz Veins at the J. Frank Zone, Valentine Lake Project

  • Channel Sample includes 4.73 g/t Au over 24.68 meters

TORONTO, Sept. 13, 2012 /CNW/ - Marathon Gold Corporation ("Marathon" or the "Company") (MOZ: TSX) today announced the discovery of multiple high-grade gold-bearing quartz-tourmaline-pyrite ("QTP") veins to the southwest of the J. Frank Zone, Valentine Lake Project, Newfoundland (Plate 1). Gold-bearing prospecting samples led to focused trenching along the Valentine Lake thrust fault, which resulted in the subsequent discovery of QTP gold vein mineralization over a 400 meter strike length and extending up to 180 meters into the hanging wall.

Channel sampling of Trench 8175 returned surface intervals of 4.73 g/t Au over 24.68 meters including 20.45 g/t Au over 3.11 meters and 11.22 g/t Au over 4.2 meters, and 2.51 g/t Au over 4.45 meters (Figure 2).

"The discovery of this new gold-rich quartz-tourmaline-pyrite veining system, which extends the J. Frank Zone 400 meters, is extremely exciting. This new discovery demonstrates that this highly prospective area covering the Sprite, the Leprechaun Gold Deposit and the J. Frank Zone is now more than 3 kilometers long," said Phillip Walford, President and CEO of Marathon Gold. "The successful results of our prospecting and trenching program at the J. Frank Zone, have led to a focused drilling program in this gold-rich area."

Highlights include:

  • Trench 8175, the first trench to be channel sampled in the newly exposed mineralized area, has returned significant widths of surface gold mineralization with 4.73 g/t Au over 24.68 meters including 20.45 g/t Au over 3.11 meters and 11.22 g/t Au over 4.2 meters, as well as 2.51 g/t Au over 4.45 meters, and 0.19 g/t Au over 10.38 meters.
  • Multiple high-grade vein grab samples, with up to 103.3 g/t Au, 141.6 g/t Au, 140.5 g/t Au and 107.0 g/t Au, have been collected from outcrop throughout the newly exposed mineralized area and justified the stripping and channel sampling (Figure 1).
  • The J. Frank Zone, including the newly discovered area of gold mineralization, has a combined strike length of over 1.25 kilometers with significant mineralization extending up to 180 meters into the hanging wall.
  • Gold-bearing QTP veins are exposed in outcrop throughout the J. Frank Zone, including the new 120 meter northeast extension of the J. Frank Zone vein, and the multiple stacked Galley veins characterized by tourmaline-rich QTP veins (Plate 1) and significant visible coarse grained gold. These veins tend to dip to the east unlike the Leprechaun Gold Deposit veins, which dip to the west, and may have been missed during drilling (Plate 2).
  • One drill is currently turning in the newly discovered southwest extension of the J. Frank Zone.

The Valentine Lake Project is 100% owned by Marathon Gold Corporation (see July 9, 2012 news release). Marathon is conducting a summer-fall 2012 program of prospecting, geological mapping and trenching along the highly prospective 23 kilometer strike length of the property outside of the current boundaries of the Leprechaun Gold Deposit.

A total of 91 drill holes totaling 24,442 meters (69.8%) of the planned 2012 drilling campaign have now been completed and there is currently one drill turning. An updated Resource Estimate based on this year's drilling results is expected to be completed in the fourth quarter.

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 Project

Marathon Gold Corporation is the 100% owner of the Valentine Lake Project. 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 1.25 kilometers 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 focused along the Valentine Lake thrust fault.

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.
