Lake Shore Gold Commences Drill Program on Gold River Trend, the Company's Third Major Timmins West Target

- Program to target Gold River Trend branch fault of the main Destor Porcupine Fault, located on the south side of Timmins West area.

- Exploration drilling to focus on expansion of previously defined near surface zones, including 18.50 gpt over 5.00 metres, 13.64 gpt over 8.20 metres, 11.15 gpt over 7.30 metres, 9.60 gpt over 6.80 metres, and extensions to depth highlighted by 1.03 gpt over 118.20 metres, including 8.64 gpt over 1.00 metre, 7.98 gpt over 1.00 metres and 5.72 gpt over 5.00 metres. Potential for both narrow high grade and wider bulk style mineralized zones.

- One drill mobilized to Gold River East Zone, two additional drills to be added by end of February, 20,000 metres of drilling planned in 2010.

TORONTO, ONTARIO--(Marketwire - Feb. 12, 2010) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the "Company") today announced the launch of the 2010 drill program on the Company's third prospective target on its 130 square kilometre Timmins West Gold Mine Complex. The Company is mobilizing three drills to the Thorne Property to test the Gold River Trend, an east-west trending mineralized deformation and alteration zone, traced for over 2.5 kilometres, located on the south side of the Timmins West sedimentary basin. The Gold River Trend is interpreted as a branch fault from the Destor Porcupine Fault with broad similarities to the Dome Fault, a major ore control of the historic Dome Mine.

The Gold River Trend varies from 50 to 200 metres in width and is dominated by strongly sheared and hydrothermally altered sedimentary and volcanic rocks which have been intruded by lenses of porphyry. Work to date indicates that at least 15 different zones of gold mineralization exist with potential for being defined as narrow high grade or wide bulk resources. In most cases the mineralization is closely associated with pyrite-arsenopyrite-ankerite-quartz veins.

Past drilling on the Gold River Trend has largely been focused on shallow targets, above 300 metres, leaving open the possibility for outlining both near surface and underground resources extending to depth. Limited previous drilling of deeper targets has highlighted the potential for depth extension, with Hole GW-09-54 intersecting 1.03 gpt over 118.20 metres, including 8.64 gpt over 1.00 metre, 7.98 gpt over 1.00 metre and 5.72 gpt over 5.00 metres at a downhole depth of 638 metres.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "We are very enthused about the potential of the Timmins West area and the Gold River Trend, and believe that a large syncline underlies the area, similar in nature to the Porcupine Syncline, which hosts the historic Timmins mines, including the Hollinger, McIntyre and Dome. The Gold River Trend has many similarities to the Dome Fault (a major ore control of the Dome Mine deposit) and the fact that historic work has outlined extensive near surface alteration and gold mineralization over a 2.5 kilometre distance, which can be expanded, demonstrates the highly prospective nature of this area.

"We plan to explore extensively at the Thorne Property, as well as at the 144 Zone, which is located south-west of Thunder Creek. We have also entered into a binding agreement to acquire five additional claims along the Gold River Trend, which emphasizes our commitment to this area as the next target of growth for Lake Shore Gold."

The majority of known mineralization defined to date is related to three main areas: North Porphyry, Gold River East and Gold River West where multiple lenses of higher grade mineralization occur in close proximity to each other.

The North Porphyry and Gold River East areas cover a combined strike length of approximately 500 metres on the east part of the trend and the West Zone a strike length of approximately 300 metres on the west end of the trend. The zones are defined by results from drill programs led by Band-Ore Resources Ltd. ("Band-Ore") in the mid-to-late 1990's and by West Timmins Mining Inc. ("West Timmins") in 2009. Recent work on the property by West Timmins tested the lower portions of both the Gold River East and West zones and indicated that the width and strength of alteration remains strong and wide to depth with several significant intercepts confirming results obtained by Band-Ore. Significant past results in the Gold River East area by Band-Ore include 9.60 gpt over 6.80 metres and 98.30 gpt over 1.20 metres in TH97-193 and 18.50 gpt over 5.00 metres, including 73.44 gpt over 1.00 metre, in TH97-158. Recent results by West Timmins in the same vicinity obtained 13.64 gpt over 8.20 metres in GS09-31 (see press release issued by West Timmins on May 12, 2009 – available at www.lsgold.com, "Other TW Properties") and 11.15 gpt over 7.30 metres in GS09-35 (see press releases issued by West Timmins on July 9, 2009 – available at www.lsgold.com, "Other TW Properties"). Significant recent results from the Gold River West area include an intercept of 1.03 gpt over 118.20 metres, including 8.64 gpt over 1.00 metre, 7.98 gpt over 1.00 metre and 5.72 gpt over 5.00 metres, at a downhole depth of 638 metres in GW-09-54 (see press release issued by West Timmins on November 4, 2009 – available at www.lsgold.com, "Other TW Properties").

Past resource estimates at the Thorne Property include a National Instrument ("NI") 43-101 compliant inferred resource for the Gold River Zone of 400,000 ounces compiled by Spiteri Geological and Mining Consultants Inc. This resource estimate assumes mainly a bulk mining concept and considerably lower gold prices than at present. Lake Shore Gold has not reviewed or verified the results from the above estimate and cannot verify its validity at this time.

The 2010 drill program for the property will consist of approximately 20,000 metres and be directed mainly towards extending the Gold River East and West zones to depth and along strike. Some preliminary testing will also be carried out of selected targets such as the Kapika Zone and Thibault horizon to gain a better overall perspective of the geological model for this region. The drilling commenced on February 10, 2010 with one drill at the Gold River East Zone, with two additional drills being added by the end of February.

In addition to the drill program on the Thorne Property, Lake Shore Gold is currently planning a drill program for the 144 Zone, also obtained through a business combination with West Timmins in November 2009, which is located on the southwest extension of the same geological contact hosting mineralization at the Thunder Creek property. The most recent work at the 144 property by West Timmins in 2009 was successful in defining very similar rock types and alteration to that found near the main mineralized zones at the Thunder Creek property. Significant results from the 2009 drilling by West Timmins on the 144 Zone included 0.63 gpt over 29.00 metres, including 11.80 gpt over 0.50 metres in a sheared and altered volcanic and porphyry.

The Gold River Trend, 144 Zone, Thunder Creek and Timmins Mine all lie within 3-4 kilometres of each other, implying that significant synergies my exist in exploring, developing and operating these properties as one large-scale mining complex.
