Please See Forward-Looking Statements Advisory

Lake Shore Gold Corp. (TSX: LSG.TO - News) ("Lake Shore Gold" or the "Company") today announced results from 29 drill holes (11,330 metres) from the Thunder Creek Project with 15 holes (2,799 metres) being collared underground near the 730 Level and 14 holes (8,531 metres) being collared on surface. The holes are part of a continuing drill program to increase drill hole density at the Thunder Creek deposit for the new National Instrument ("NI") 43-101 estimate due later this year as well as to explore for new deposits along strike.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's results continue to provide us with a very positive outlook on the Thunder Creek deposit and its potential. Drilling is proceeding well with infill holes extending mineralization above and below the 730 Level. As well, the discovery of a potential new zone 500 metres from the Thunder Creek deposit highlights the excellent opportunity that exists for new discoveries along the TC-144 trend. We are continuing our aggressive drill program at Thunder Creek with 12 drills currently active in support of our efforts to establish an initial NI 43-101 report later this year and to pursue expansion of the Thunder Creek deposit towards 144."

Underground drilling confirms and extends mineralization above and below 730 Level.

Holes drilled to test above the 730 Level covered up to the 650 Level and provided strong confirmation of the upward continuity of previously obtained wide, high-grade intercepts in horizontal holes on the 730 Level. Key intercepts include 7.75 gpt over 108.80 m in 730-012, 4.70 gpt over 145.70m in 730-010, 10.19 gpt over 55.00m, including 18.95 gpt over 20.50m, and 4.90 gpt over 50.80m in 730-011 and 5.21 gpt over 49.70m, including 8.11 gpt over 24.90m and 3.70 gpt over 12.25m, in 710-001.

Results of drilling below the 730 Level covered the mineralized zone to a maximum depth of 900 metres below the level and were also highly successful. Key intercepts from below the level included 7.01 gpt over 112.70m in 730-013, 2.30 gpt over 120.55m in 730-030 and 4.21 gpt over 9.10m and 0.90 gpt over 91.30m in 650-007.

Underground drilling near northeast tip of Porphyry Zone on 730 Level extends mineralization by minimum 25 metres.

Drilling near of the northeast limit of the Porphyry Zone on the 730 Level were designed to test for a possible extension of the Zone and was also successful, extending the Zone by a minimum of 25 metres. Results include 3.62 gpt over 40.50m in 730-014, 7.24 gpt over 6.30m in 730-024 and 2.53 gpt over 23.90m in730-029. Including the results of these new holes the total strike length of the Zone on the 730 level now stands at a minimum of 200 metres

Infill drilling from surface confirms mineralization between 500 and 630 metre levels.

Significant results from the infill drilling include 4.17 gpt over 29.60m in TC08-054d, 7.75 gpt over 8.00m in TC08-054b and 5.65 gpt over 69.90m, including 10.45 gpt over 21.60m in TC11-112. These holes intersected mineralization approximately 200 metres above the 730 Level and confirm the continuity of thick, high-grade intersections towards the 350 metre level, which is one of the next areas scheduled for development.

Exploration surface drilling extends mineralization and discovers potential new zone 500 metres to the southwest.

Among significant results from drilling to the southwest were 6.72 gpt over 8.90m, including 26.82 gpt over 1.40m in TC09-69k, 11.49 gpt over 5.00m in TC11-111b and 9.10 gpt over 2.00m in TC11-111a. All three holes were drilled on a section located 25 metres southwest of the current limit for the Thunder Creek deposit where there is little to no previous testing. TC09-69k intersected the Zone approximately 200 metres above the 730 Level, while TC11-111a and TC11-111b intersected mineralization approximately 100 to 150 metres above 730 Level. The potential to extend the Zone further to the southwest is considered excellent.

Additional results from drilling to the southwest included 8.07 gpt over 2.01m in TC10-085a, which was collared approximately 500 metres to the southwest of the Thunder Creek deposit. The intersection consisted of a 20 metre alteration zone containing local porphyry dikes, quartz veining and increased sulphides similar to the Thunder Creek deposit. It is considered highly significant as it confirms the southwest extension of the TC-144 trend and its potential to host additional new deposits.

Observations to date continue to confirm the continuity and grade of the Thunder Creek deposit and indicate a broad envelope of mineralization containing multiple higher-grade lenses in both the Rusk and Porphyry zones.

The broad envelope of mineralization has been traced from surface to a vertical depth of 1,000 metres and has an average strike length of approximately 200 metres and average width which varies between 5 and 100 metres. The bulk of the drilling to test the mineralized envelope zone has been concentrated on a 200 metre strike length between surface and the 800 level with results indicating excellent continuity and potential for further expansion.

Drilling is continuing at the Thunder Creek property with 12 drills, including four underground drills near the 300 Level, four underground drills near the 730 Level and four drills on surface. The deepest holes to test the zone to date are at a vertical depth of 1,000 metres and indicate that the Rusk and Porphyry zones are open to depth and that the Porphyry stock hosting the Porphyry zone is increasing in size.

Quality Control

The Company's Qualified Person ("QP") for the drilling being completed on the Thunder Creek property is Dean Crick, P. Geo. As QP, he has prepared or supervised the preparation of the scientific or technical information and has verified the data disclosed in this press release. Mr. Crick is an employee of Lake Shore Gold.

Lake Shore Gold has a quality control program to ensure best practices in the sampling and analysis of all drill core. Assays have been completed at ALS Chemex (TC200 series holes) which uses a standard fire assay with a 30-gram aliquot. For samples that return a gold content greater than 10.0 gpt, the sample is re-analyzed via Fire Assay with Gravimetric finish. Select mineralized sections of the Porphyry Zone are analyzed using the "metallics" or screen fire assay technique. Drill core is saw cut and half the 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 to the ALS Chemex Prep Lab located in Timmins, Ontario. The pulps from core that is sent to the ALS Chemex Prep Lab are then shipped to ALS Chemex Assay Laboratory in Vancouver, BC. ALS Chemex is an ISO 9001-2000 registered laboratory preparing for ISO 17025 certification.
