Lake Shore Gold Corp. (LSG.TO)(NYSE MKT:LSG) ("Lake Shore Gold" or the "Company") today announced results from 48 holes totaling 13,916 metres ("m") of exploration drilling at the Timmins West Mine. The holes being reported represent the bulk of the 20,000 m exploration program announced in January 2014. 40 holes (9,540 m) were designed to test the S2 Fold Nose, a second fold nose structure similar to the main Timmins Deposit fold nose which hosts most of the Deposit's existing reserves, as well as depth extensions of the Ultramafic and Footwall zones between the 790 and 1050 m levels. An additional eight widely-spaced holes (4,376 m) were drilled to explore the contact between the Timmins Deposit and Thunder Creek. All drilling was completed from five main platforms at the Timmins Deposit located on the 750, 790 and 830 levels.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's results from drilling in the S2 Fold Nose confirm the presence of elevated gold values and identify opportunities for extensions and new areas of gold mineralization. The S2 Fold Nose is a high potential exploration target with similar characteristics to the Deposit's main fold nose structure. Intersecting high-grade mineralization in both the North and South limbs of the S2 Fold Nose is very encouraging, with additional drilling now planned for the purpose of proving continuity of the zones in both limbs.

"Today's results come two weeks after we announced the intersection of wide, high-grade mineralization in the 144 Gap. A review of the geology at Thunder Creek and 144 increasingly suggests that there may be multiple lenses of gold mineralization southwest of Thunder Creek extending into the 144 Gap with the potential for additional deposits further along the Thunder Creek-144 Trend. Considering recent drill results at both Timmins Deposit and Thunder Creek, we are increasingly optimistic about the potential to identify new resources at Timmins West Mine as more work is completed. Given the proximity of new mineralization in the S2 Fold Nose and Thunder Creek to existing mine development (between 100 and 700 m), the Company is planning to establish exploration drifts into these areas as part of a more aggressive underground exploration program."

Significant intercepts from the North Limb and nose of the S2 Fold Nose include 12.32 grams per tonne ("gpt") over 9.3 m, including 27.7 gpt over 3.3 m in 830-044, 5.57 gpt over 11.6 m in 750-045 and 11.72 gpt over 9.7 m, including 28.84 gpt over 1.6 m, in 790-056. These results were obtained in areas near the 890 Level along strike of existing resource blocks.

Significant intercepts from the South Limb near the 790 Level include 12.85 gpt over 5.4 m, including 23.50 gpt over 3.0 m, in 790-150, 3.79 over 8.3 m in 790-152, 23.73 gpt over 5.0 m, including 98.40 gpt over 1.0 m, in 790-153, 7.82 over 3.6 m in 790-156 and 4.08 gpt over 4.0 m in 790-158. Most of the holes were drilled on two cross sections east of existing resource blocks with the mineralized zones remaining open to the east.

Drilling below current resource shapes for the Footwall and Ultramafic zones between the 790 and 850 levels also returned significant intersections. Among these intercepts are 6.28 gpt over 4.2 m in 750-013, 38.56 gpt over 3.1 m in 790-089, 14.80 gpt over 4.9 m in 790-114 and 7.10 gpt over 5.50 m in 790-092.

Interpretation of the new data suggests mineralization occurs within a series of lenses surrounding the S2 Fold Nose with variable sizes and grades. Tighter-spaced drilling is planned in order to more fully assess the resource potential of both the North and South limbs.

Eight widely-spaced holes (4,376 m) were also drilled to explore along the contact between the Timmins and Thunder Creek deposits. No significant gold values were intersected from this drilling.

In conjunction with an ongoing surface drill program at the 144 Property, the Company has conducted a review of the geology between the Thunder Creek Deposit and the discovery holes announced 770 metres to the west (see press release issued October 7, 2014). Results of this review indicate that the Thunder Creek Deformation Zone has been offset by local faulting with there being no significant testing below the 700 m level. The review also indicates excellent potential for multiple porphyry intrusions and additional gold mineralization immediately southwest of Thunder Creek along the Thunder Creek-144 Trend. Surface drilling to further evaluate this potential is in progress.

Qualified Person

The Qualified Person ("QP") for Lake Shore Gold's drill program at the Highway 144 Property is Senior Vice-President Exploration, Eric Kallio, 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. Mr. Kallio is an employee of Lake Shore Gold.

Quality Control

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 either in Sudbury, ON, or to Val d'Or Quebec and the pulps are subsequently shipped to the ALS Minerals assay laboratory facility in Val d'Or, Quebec (or rarely 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).
