Resource Confidence and Open Pit Mining Potential Grows with Results from Infill Drilling of Leprechaun Deposit at Valentine Lake Joint Venture, Newfoundland

See all 2011 drill results to date with latest maps, sections and photos at www.mountain-lake.com

HALIFAX, Nova Scotia--()--Mountain Lake Resources Inc. (TSX-V: MOA) (Pink Sheets: MLKRF) (“Mountain Lake” or the “Company”) is pleased to report the results of infill drilling at the Leprechaun Gold Deposit on the Valentine Lake Property in central Newfoundland. The infill drill holes were focused in the northeast (VL-11-310, VL-11-311, VL-11-313, VL-11-316 and VL-11-318) and southwest (VL-11-309, VL-11-312, VL-11-314, VL-11-315 and VL-11-317) areas of the current Leprechaun Deposit resource boundary (Figure 1). Each of the ten drill holes intersected significant zones of gold mineralization and confirmed the continuity of the mineralized zones along strike between adjacent sections within the Leprechaun Deposit.

The Valentine Lake Property Project is a 50/50 joint venture between Marathon Gold and Mountain Lake with the Leprechaun Gold Deposit situated at the south-western end of a 23 kilometre (km) long gold-bearing mineralized corridor. Marathon is the operator of the Project, and the Partners are jointly funding a $7.1 million resource expansion and exploration budget in 2011. Year to date, a total of 111 drill holes totaling 18,098 metres (m) (72%) of the planned 25,000m drilling campaign have been completed. The balance of the 2011 drilling is expected to be completed in October with results being released as available into the fall, and an updated resource estimate for the Leprechaun Deposit is scheduled for completion before year’s end.

Highlights:

  • Infill drill holes in the northeast, with near surface intercepts of up to 1.88 g/t Au over an estimated true width of 32.3m as in VL-11-310, confirm the predicted continuity of mineralization along strike between adjacent sections in the Deposit.
  • Drill hole VL-11-313 proves the down–dip expansion of the Deposit with the high grade footwall intersection of 6.53 g/t Au over 2.4m including 22.63 g/t Au over 0.6m.
  • Infill drill holes in the southwest, with intercepts of up to 2.7 g/t Au over 12.8m including 10.69 g/t Au over 2.6m in VL-11-317, as well as 2.38 g/t Au over 16.2m in VL-11-314 confirmed the predicted continuity of mineralization along strike between adjacent sections in the 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. Results from fire assay are used for drill hole planning only. Assay results for the future updates of the December 2010 resource estimate 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 using standard fire assay techniques. The reported values in this release are fire assay results. No lower cut off was applied during calculation of the composite grades.

About the Valentine Lake Joint Venture: The Valentine Lake Project is a 50/50 joint venture between Marathon Gold and Mountain Lake. The Leprechaun Gold Deposit (750 metre strike length) is situated at the south-western end of the 30 kilometre Valentine Lake Property with the Sprite Zone and the Valentine East Zone located ~700 metres and ~13 km respectively along strike to the northeast. These gold occurrences form part of a 23 km long, highly prospective, gold-bearing mineralized corridor. Marathon is the operator of the Project, and the Partners are jointly funding a $7.1 million resource expansion and exploration budget in 2011 that includes 25,000 metres of drilling.

Leprechaun Gold Deposit: The Deposit has a 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; and an associated Inferred resource of 4,409,000 tonnes grading 2.01 g/t gold for an estimated 285,000 ounces of gold (see news release of December 16, 2010). The 2010 resource was estimated using a 0.5 g/t gold minimum cut-off over a 3 metre minimum width. The Deposit is open at depth and along strike with 74% of the current Measured & Indicated ounces occurring within 150 metres of surface. For more information see the news releases detailing the 2011 exploration results which have been announced: February 3, February 18, March 2, March 8, March 29, April 26, May 4, June 29, July 27, August 9 and August 25.
