Lake Shore Gold Announces Major Extensions to Timmins Mine Mineralization, Thunder Creek Rusk Horizon

- TG08-178f intersects 8.11 gpt over 6.00 metres, including 15.92 gpt over 2.50 metres, extends Timmins Mine mineralization within newly emerging fold nose at depth 130 metres down plunge and 100 metres to the west of previous limit for drilling. - TG08-178f intersects Rusk Horizon in Timmins Mine area, Rusk Horizon extended to 1,700 metre vertical depth, 700 metres below previous deepest intersection. - TG09-181 intersects 7.71 gpt over 2.20 metres, including 13.15 gpt over 1.10 metres, approximately 70 metres above TG08-178f, 100 metres west of the previously defined Timmins Mine mineralization. - TG05-74f intersects 6.21 gpt over 10.10 metres and TG05-74e intersects 7.16 gpt over 2.50 metres, highlight potential to add new resources between 875 metre and 1,200 metre levels at Timmins Mine.

TORONTO, ONTARIO--(Marketwire - Feb. 18, 2010) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the "Company") today announced results from 1 hole (1,572 metres) and 9 wedge holes (6,382 metres) from surface drilling conducted on the Timmins Mine property. The most significant results were from TG08-178f which intersected 8.11 gpt over 6.00 metres, including 15.92 gpt over 2.50 metres, approximately 130 metres down plunge and 100 metres to the west of the previously defined Timmins Mine mineralization at a 1,330 metre vertical depth (1,485 metres down plunge). The intersection occurs in strongly deformed mafic volcanic rocks containing ankerite-albite alyeration and 2-5% sulphides (Footwall style mineralization). TG08-178f is interpreted to have passed through the top of a newly emerging fold nose located to the north of the main or South ultramafic fold nose which controls the bulk of mineralization at the Timmins Mine, including the mineralization currently being drilled and developed on the 650 Level.

TG09-181 passed 100 metres west of previous drilling and approximately 70 metres above TG08-178f and the newly emerging fold nose and returned an intersection of 7.71 gpt over 2.20 metres, including 13.15 gpt over 1.10 metres and 7.54 gpt over 1.95 metres within the main or South ultramafic fold nose. This intersection occurred in altered proxenite with quartz-tourmaline veining and 5-10% sulphides (Ultramafic Zone style mineralization). The development of multiple plunging fold structures that host mineralization as illustrated by the newly emerging North and South folds present a structurally complex setting favorable for gold mineralization that remains open down plunge.

TG08-178f was extended below the Timmins Mine to test the projection of the Thunder Creek Rusk Horizon. The hole intersected an 18 metre interval of moderately sheared and hydrothermally altered ultramafic rock at the same contact with sedimentary rocks which correlates with the Rusk Zone Horizon. The Rusk Horizon was intersected 1,700 metres vertically below surface and 700 metres vertically below the last known intersection in previously released Hole TC09-73 (see press release dated August 25, 2009 for more information). The hole also intersected a small lens of porphyry similar to those found north of the better mineralized portions of the Rusk zone on higher elevations. This geological setting is considered highly favourable for additional gold mineralization.

Holes TG05-74f and 74e were infill holes, targeting gaps in the Timmins Mine resource between the 875 metre and 1,200 metre levels near section 4550E. The best results include 6.21 gpt over 10.10 metres in TG05-74f and 7.16 gpt over 2.50 metres in TG05-74e, both in the North Ultramaic fold structure. The holes confirm vertical continuity and extensions to the Ultramfic Zone up to 45 metres below TG05-74c, which intersected 7.87 gpt over 33.60 metres in 2005. These intersections occur in gaps in the existing resource and show the potential to add new resources within this area between the 875 metre and 1,200 metre levels.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's drill results are extremely encouraging for the potential of our Timmins West Gold Mine Complex. Hole TG08-178f demonstrates that gold mineralization at Timmins Mine extends to a vertical depth of 1,330 metres below surface (1,485 metres down plunge) and 100 metres to the west of the current resource boundary, which greatly expands the possibility to add new resources. This hole also substantially extends the depth potential of the Thunder Creek Rusk Horizon to at least 1,700 metres vertically, an extension of 700 metres below previous drilling. In addition, holes TG05-74f and 74e highlight the potential to locate additional resources in areas above the 1,200 metre level at Timmins Mine."

Drilling at Timmins Mine is continuing with one surface drill rig which will complete a series of wedge holes from TG08-178f to explore for additional resources at Timmins Mine and for further extensions of the Rusk and Porphyry zones at Thunder Creek. To compliment planned drilling, the Company is currently preparing for a downhole geophysical survey to assist in detailed targeting of the Rusk Zone horizon, porphyries and gold mineralization.

Quality Control

The Company's Qualified Person ("QP") for surface drilling for the Timmins Mine property is Pat Pope, P.Geo. As QP, he has prepared or supervised the preparation of the scientific or technical information for the properties and has verified the data disclosed in this press release. Mr. Pope is an employee of Lake Shore Gold.

Lake Shore Gold has implemented a quality-control program to ensure best practice in the sampling and analysis of the 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. Select mineralized zones or 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.
