Drilling in the 144 Gap included five holes and one extension hole (5,456 m) drilled within a 1.6 km strike length along the TC-144 trend between the 144 North Zone and the Thunder Creek Deposit. The most significant intercepts from this drilling include 13.54 gpt over 2.0 m and 6.07 gpt over 3.0 m in Hwy-12-40, which crosses the TC-144 Trend approximately 850 metres south of the Thunder Creek Deposit at an elevation of 700 metres below surface. The new intersection is closely associated with strong hydrothermal alteration and narrow bands of syenite, increased concentrations of quartz and pyrite. Preliminary interpretation suggests that this intersection reflects the top of a new syenite body similar to that found at Thunder Creek and 144 North. This intersection, along with previously released hole TC10-85A with 8.07 gpt over 2.1 m (press release dated July 26, 2011), illustrates the extension of the favourable Thunder Creek structure through the largely unexplored 144 Gap area and with drillhole intersections showing features favourable to host significant mineralization.

Drilling at 144 North included 16 holes (12,514 m) which were designed to extend previously identified zones to depth. Among key intersections, all between 150 – 300 m elevations, were 3.59 gpt over 7.5 m, including 11.84 gpt over 1.5 m and 8.93 gpt over 1.0 m, in Hwy-11-14 and 3.36 gpt over 5.3 m and 6.90 gpt over 1.5 m in HWY-11-17. Additional significant intersections between 350 – 900 m elevations include: 5.10 gpt over 3.0 m, including 10.35 gpt over 1.0 m, and 3.33 gpt over 6.9 m, including 10.18 gpt over 1.7 m, in Hwy-12-43; 1.02 gpt over 51.7 m and 5.14 gpt over 3.0 m in Hwy-11-19; and 1.02 gpt over 27.5 m, including 6.24 gpt over 2.5 m, and 1.00 gpt over 46.0 m, including 2.36 gpt over 10.0 m and also including 11.35 gpt over 1.0 m, in Hwy-11-20.

The intersection in Hwy-12-43 at 900 m elevation is the deepest drilled in this area to date. Based on observations from drill core, mineralization in this area is contained in a series of lenses which occur on the upper and lower contacts of a large syenite stock. The overall plunge of the stock appears to vary between 60 to 65 degrees NE towards Thunder Creek. As with mineralization at Thunder Creek, the better zones of mineralization are often closely associated with strong hematite alteration and increased pyrite and quartz vein content.

Drilling at 144 South includes 14 holes (8,900 m) covering an 1,000 m strike length along the projected TC-144 trend to a maximum vertical depth of 550 m. Significant intersects include: 12.60 gpt over 1.3 m and 1.30 gpt over 57.7 m, including 4.06 gpt over 7.6 m, in Hwy-11-28; 202.00 gpt over 0.30 m in Hwy-11-30; 2.01 gpt over 41.7 m, including 14.76 gpt over 3.0 m and 3.82 gpt over 5.6 m, in Hwy-12-45; and 5.69 gpt over 4.7 m in Hwy-12-42. Most of the significant assay values obtained to date are located in the northeast portion of a 600 m long hydrothermal alteration zone where, like 144 North, it has been intruded by a syenite stock. The best mineralization identified to date is between 300 and 450 m below surface and is closely associated with the northeast tip of the stock. The projected plunge of the stock is steep to the northeast and remains untested to depth.

Three holes (HWY-12-34 to 36) were drilled as step-outs along strike of the above intercepts to test for shallow mineralization up to 500 m to the southwest. All holes intersected zones of strong hydrothermal alteration and bleaching up to 200 m thick.

In addition to the above, a short extension hole was also drilled to test the depth potential of a large syenite stock located approximately 500 m south of Thunder Creek. The stock is considered to have strong similarities to rocks hosting the Thunder Creek Deposit but has had limited exploration to date. Results of the recent program showed strongly anomalous gold assays near both the upper and lower contacts of the stock which are considered very positive for future potential.

The most recent drill program at 144 was completed late in 2012. The main focus of future drilling will be to test the projected down plunge extensions of newly identified mineralization at the 144 Gap and South areas.

Quality Control

The Qualified Person (“QP”) for Lake Shore Gold’s drill program at the Highway 144 property isKara Byrnes , P.Geo. who, as a QP, has prepared or supervised the preparation of the scientific or technical information for the property and verified the data disclosed in this press release. Ms. Byrnes 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 10 grams per tonne gold, the sample is fire assayed with a gravimetric finish. Select 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 Minerals Preparation facility located inTimmins, ON, and the pulps are subsequently shipped to the ALS Minerals assay laboratory facility in Val d’Or, Quebec or in North Vancouver, B.C for fire assay. These ALS Minerals facilities are all registered ISO 9001-2008 (CERT-0051527). The Val d’Or assay laboratory is SCC ISO/IEC 17025:2005 Accredited (#689) and the North Vancouver, BC assay laboratory is also SCC ISO/IEC 17025:2005 Accredited (#579).
