MARATHON'S INFILL DRILLING CONTINUES HITTING NEW HIGH-GRADE OPEN-PIT GOLD: 12.49 G/T AU OVER 13.0M, 4.19 G/T AU OVER 12.0M AND 3.73 G/T AU OVER 15.0M, VALENTINE LAKE GOLD CAMP, NL

Marathon Gold Corp. has released continuing excellent results from infill drill holes which were strategically located between existing, strongly mineralized drill holes in the open-pit portion of the Marathon deposit. The drill holes succeeded in intersecting strongly mineralized, en echelon stacked QTP-Au veining with thick intervals of higher-grade gold intercepts. The intent of the infill drilling program is twofold: first, to further confirm Marathon's geological model by demonstrating the extensive lateral continuity of the QTP-Au (quartz-tourmaline-pyrite-gold) veining into adjacent drill holes both along and across a more-than-140-metre strike that has been infill drill tested so far; and second, to continue to upgrade inferred resource material into the measured and indicated resource categories.

"The continued success of the infill drilling campaign at the Marathon deposit is very important as we not only continue to build economic gold resources focused on open-pit mining of the Marathon deposit, but also continue to further validate our geological model with each drill hole that intersects new VG and wide intervals of high-grade gold between previous adjacent drill holes," said Phillip Walford, president and chief executive officer of Marathon Gold. "The very positive drilling results are expected to lead to a significant upgrade of inferred to measured and indicated resources while also adding additional inferred material. Assays are pending on more drill holes with wide intervals of VG-bearing QTP veining."

Quality assurance/quality control (QA/QC)

Ms. Dunsworth, Marathon's qualified person, has reviewed the contents for accuracy and has approved this press release on behalf of Marathon. Thorough QA/QC protocols are followed including the insertion of blanks and standards at regular intervals in each sample batch. Drill core is cut in half with one-half retained at site, the other half tagged and sent to Eastern Analytical Ltd. in Springdale, Nfld. All reported core samples are analyzed for Au by fire assay (30 g) with AA (atomic absorption) finish. All samples above 0.10 g/t Au in economically interesting intervals are further assayed using metallic screen to mitigate the presence of coarse gold. Significant mineralized intervals are reported in the associated table as core lengths and estimated true thickness (95 per cent of core length).
