Valentine Lake Joint Venture intersects New High-Grade Lens at Leprechaun Gold Deposit Grading 8.15 g/t Au Uncut Over 20 Metres (TW) in Upper Zone of Deposit

Valentine Lake Joint Venture intersects New High-Grade Lens at Leprechaun Gold Deposit Grading 8.15 g/t Au Uncut Over 20 Metres (TW) in Upper Zone of Deposit

Marathon Gold Corporation and Mountain Lake Resources Inc. are pleased to announce very positive results from the first 5 diamond drill holes of the 2011 Valentine Lake Property drilling campaign (see 2011 drill hole plan map on either companies’ website). The drilling has focused in the NE portion of the Leprechaun Gold Deposit and has resulted in the discovery of three new high-grade lenses including 8.15 g/t uncut over 25m (45-70m) with 21.12 g/t uncut over 9m (45-54m) in VL-11-232. These new mineralized lenses are shallow dipping within the hanging wall zone of the deposit and at depths of less than 60m from surface. Main zone intercepts of up to 3.73 g/t over 20m including 5.39 g/t over 10m were identified in VL-10-236. Marathon is the operator of the project.

The second drill rig, which started drilling at Valentine East late last week, has intersected quartz-tourmaline-pyrite veins in the first drill hole (VE-11-01).


* High-grade hanging wall lens in VL-11-232 graded 8.15 g/t uncut over 25m (45-70m) including 21.12 g/t uncut over 9m (45-54m) * High grade hanging wall lens in VL-11-235 graded 14.97 uncut g/t over 3.97m (3.03-7m) including 61.03 g/t uncut over 0.97m (3.03-4m) * Hanging wall lens in VL-11-236 graded 3.75 g/t over 11m (8-19m) including 8.04 g/t over 4m (8-12m) * Main Zone intercept in VL-11-236 graded 3.73 g/t over 20m including 5.39 g/t over 10m * Coarse (up to 1mm) free gold observed in VL-11-232 and VL-11-236 (see photos on either companies’ website) * The ongoing infill drilling is expected to continue to increase the Measured and Indicated Resource for the Leprechaun Gold Deposit * Drilling will continue in the NE part of the Leprechaun Deposit until site conditions allow for step out drilling further to the NE into the Sprite zone as well as westward into the hanging wall of the main deposit.

* Drilling has commenced at the Valentine East Zone with intersection of mineralized quartz-tourmaline-pyrite veins in the first drill hole (VE-11-01). The next planned drill hole (VE-11-02) will collar into an area between known mineralization and the contact zone where there is no historical drilling.

Sherry Dunsworth, V.P. Exploration for Marathon Gold says, “The exploration program at Valentine Lake is off to an excellent start this year. We have intersected new high grade gold intercepts over wide intervals and that is with just 2% of this year’s planned 25,000m drilling campaign. The Leprechaun drilling is designed to upgrade inferred resources into measured and indicated resources as well as increasing the overall resource. Marathon is looking forward to future results as we continue to step out testing targets at increased depth and along strike to the NE of the Leprechaun Gold Deposit as well as in the Valentine East Zone.”

Gary Woods, President and CEO of Mountain Lake added, “The presence of significant gold intercepts in the hanging wall will be very important to the economics of the project and will have a big impact on the ore to waste ratio in an open pit operation.”

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

All of the samples were sent to Eastern Analytical Laboratory Ltd., in Springdale, Newfoundland. Samples were assayed using lead collection fire assay with AA (atomic absorption) finish. Results from fire assay are used for drill hole planning only. Assay results for the planned update of the December, 2010 resource will be determined by an ongoing metallic screening process. Due to the coarse nature of the gold at the Leprechaun Deposit, the metallic screening method is used on economically important intersections followed by standard fire assay techniques. The reported values in this release are fire assay results.

Valentine East Zone: Valentine East is a gold zone located 13 km along strike to the northeast of the Leprechaun Deposit. Twenty one widely spaced drill holes tested the zone over a strike length of 800 m. Most of the drilling was focused on mineralization approximately 250 m northwest of the sedimentary contact with the gold bearing granite. These holes indicated potential for wide zones of low-grade gold mineralization near surface. The best hole was VL99-17, which intersected 61.06 m grading 1.09 g/t; however 39.91 m of that intercept was not sampled and was therefore added as zeros values to the grade calculation. The current program will test the potential of this zone and the 250 m of rock to the sedimentary contact where some gold has been found on surface and in 4 historical drill holes drilled along the granite/sedimentary contact
