Lake Shore Gold Continues to Establish Large Gold System at Thunder Creek, Porphyry Structure Extended to at Least 1,125 Metre Depth

- TC09-68d intersects 12.17 grams per tonne (gpt) gold (Au) over 9.00 metres (m) within an overall drill intersection of 3.73 gpt over 80.30 m - TC09-68c intersects 21.86 gpt over 1.70 m, 9.13 gpt over 0.70 m, 3.17 gpt over 15.00 m and 4.17 gpt over 13.35 m from within an overall zone of 2.34 gpt over 100.25 m - TC09-73 successfully extends main Porphyry structure, with gold mineralization, to 1,125 metre vertical depth, potential for additional high-grade zones at this depth and below considered excellent - Four additional holes completed, results pending

TORONTO, ONTARIO--(Marketwire - Aug. 25, 2009) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the "Company") today announced results for three new holes, TC09-68c, TC09-68d and TC09-73, (2,447 metres) as part of its ongoing 22,000 metre diamond drill program at the Thunder Creek joint venture property, located immediately adjacent to Lake Shore Gold's 100% owned Timmins Mine project. The Company holds a 60% interest in the Thunder Creek property, and is the operator of the joint venture with West Timmins Mining Inc.

TC09-68c was designed to test the Rusk and Porphyry zones approximately 55 metres metres up dip from previously released hole TC09-68b (which included 12.75 gpt over 83.40 m). TC09-68c intersected multiple zones of mineralization including 21.86 gpt over 1.70 m, 9.13 gpt over 0.70 m and 3.17 gpt over 15.70 m, including 23.20 gpt over 0.50 m from the Rusk Zone and 4.17 gpt over 13.35 m from the Porphyry Zone.

TC09-68d was wedged from TC09-68c and further extended the zones of mineralization by another 35 to 40m above TC09-68c. Best intercepts in TC09-68d include 4.85 gpt over 15.70 m from the Rusk Zone, and 12.17 gpt over 9.00 m in the Porphyry. The intercepts from the Rusk Zone display strong iron-carbonate alteration within a sheared contact zone including ultramafic, sedimentary and volcanic rocks, accompanied by quartz-carbonate veining, felsic dykelets and locally strong pyrite dissemination. Mineralization in the Porphyry Zone is characterized by local quartz veining, accompanied by minor sphalerite, galena, molybdenite, scheelite and pyrite. Fine visible gold specks are commonly observed at several locations within the intrusive. When the Rusk and Porphyry zones are combined as one mineralized interval, the composite grade intersected is 2.34 gpt over 100.25 m in Hole TC09-68c and 3.73 gpt over 80.30 m in Hole TC09-68d. When compared to previously released Hole TC09-68b, the widths are similar but the grades lower. The lower grades are attributable to natural variability of gold content within the overall system which is typical of high grade coarse gold deposits. Along with previously release holes TC08-54 (5.90 gpt over 26.35 m) and TC09-68 (2.87 gpt over 71.75 m), these intersections define a thick mineralization envelope over a minimum 250 m vertical height incorporating the entire porphyry and portions of the Rusk Zone. This adds a prospective new target with bulk and/or high grade potential for the project.

TC09-73 was a major "step-out" hole designed to explore for the Rusk and Porphyry zones approximately 245 metres down dip from Hole TC09-68 and is the deepest hole drilled at the property to date. However, due to technical problems the hole had to be abandoned before crossing through the entire Porphyry unit. Before being abandoned, TC09-73 intersected the Rusk Zone and the north side of the gold bearing Porphyry unit. Where intersected, the porphyry displayed local silicification, hematization and sporadic quartz veining containing base metals, molybdenite and scheelite, which are characteristic of previously reported high grade zones from within the Porphyry. The Porphyry also contained a generally elevated level of gold with the best intercepts ranging from 2.51 gpt to 2.89 gpt over 0.50 m widths.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "The results continue to expand the mineralized structures at Thunder Creek and suggest the presence of a large scale gold system on the property which is closely linked to a major Porphyry body. The Porphyry system remains open in both directions and to depth. We took a major step out with Hole TC09-73, drilling 245 metres (approximately 800 feet) down dip from our previous deepest hole and, as a result, successfully extended the mineralized porphyry unit to a vertical depth of 1,125 metres and confirmed that several good indicators for higher grade mineralization found in holes above were still present at this depth. As such, the potential for high grade zones to this depth and even further is considered excellent and the company plans to pursue this opportunity aggressively with our future drilling. We have four additional holes completed with results pending and currently have three drills working on the property."

Quality Control

The Company's Qualified Person ("QP") for the Thunder Creek property is Jacques Samson, P. Geo. As QP, he has prepared or supervised the preparation of the scientific or technical information for the property and has verified the data disclosed in this press release.

Lake Shore Gold has a quality control program to ensure best practices in the sampling and analysis of drill core. Assays have been completed using a standard fire assay with a 30-gram aliquot. For samples that return a value greater than three grams per tonne gold, another pulp is taken and fire assayed with a gravimetric finish. Zones with visible gold are tested by pulp metallic analysis. NQ size drill core is saw cut and half the drill core is sampled in standard intervals. The remaining half of the core is stored in a secure location. The drill core is transported in security-sealed bags for preparation at ALS Chemex Prep Lab located in Timmins, Ontario, and the pulps shipped to ALS Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO 9001-2000 registered laboratory preparing for ISO 17025 certification.
