Lake Shore Gold Corp. (TSX:LSG) (NYSE MKT:LSG) ("Lake Shore Gold" or the "Company") today announced results from 60 holes and 11 wedge cuts (39,050 metres) of new surface and underground drilling at the 144 Trend. Of the holes being reported, 40 holes and nine wedge holes (13,945 metres) were completed as part of a detailed delineation program at the 144 Gap Zone designed to gain information in support of establishing a first resource estimate by early in 2016. Of the 40 holes, 39 holes (7,165 metres) were from underground drills working off the now completed exploration drift from Thunder Creek into the 144 Gap area, while one hole and nine wedge holes (6,780 metres) were drilled from surface. The remaining holes include 20 surface holes and two wedge holes (25,438 metres) were drilled mainly at the 144 Gap SW Zone and 144 South in order to advance the company's geological model and evaluate potential new targets for exploration to the southwest of the 144 Gap Zone.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's drill results are very significant and include additional high-grade intercepts from delineation drilling at the 144 Gap Zone and the discovery of new zones of mineralization at 144 South, approximately 1.6 km further away. As with our initial underground drill results in the 144 Gap area released in September, the holes released today are similar to, and in some cases better than, the results from earlier surface drilling in the same areas. We are also very pleased with initial results from our surface exploration program, which continues to demonstrate our ability to identify new zones of gold mineralization as we move to the southwest from the 144 Gap Zone and highlights the considerable potential of the 144 Trend to host multiple gold deposits. With our exploration drift completed, we now have six underground drills operating at the 144 Gap Zone and remain on track to achieve our objective of releasing a first resource early in 2016."

Among significant results received from new underground delineation holes (see Table 1.) that were collared from the recently completed exploration drift from Thunder Creek were 6.85 gpt/ 59.2 metres ("m") from HW820-055 (see Figures 3 and 4). This hole represents the first hole drilled from underground to test the western portion of the 144 Gap Zone. Results also included 79.52 gpt/8.3 m, including 1000 gpt/0.6 m in HW820-16, 26.09 gpt/7.8 m in HW820-10, 5.29 gpt/18.1 m and 5.97 gpt/17.7 m in HW820-13, 5.36 gpt/28.1 m in HW820-18, 11.64 gpt/8.9 m and 6.98 gpt/36.1 m in HW820-19, 6.05 gpt/31.5 m in HW82-31 and 10.91 gpt/11.9 m, 5.19 gpt/13.3 m and 4.15 gpt/19.5 m in HW820-020 (see Figures 3 and 5). These additional holes were drilled near the east portion of the 144 Gap Zone between the 700 and 950 metre levels in order to follow up on initial results from underground drilling announced on September 16, 2015 (see press release entitled "Lake Shore Gold Reports High-Grade Intersections From Initial Underground Drilling at 144 Gap Zone").

Among significant results from surface delineation drilling to date (see Table 2.) are 12.13 gpt/13.8 m in Hwy-15-94W2, 6.58 gpt/28.1 m in Hwy-15-48W3, 4.78 gpt/13.0 m in Hwy-15-84W2, 5.76 gpt/24.5 m and 4.78 gpt/13.9 m in Hwy-15-87W3, 4.96 gpt/20.4m and 8.47 gpt/5.3m in Hwy-15-84W4, 4.06 gpt/21.7 m and 4.29 gpt/15.1 m in Hwy-15-94W1 and 3.23 gpt/16.9 m in Hwy-15-106W1. The new holes were drilled to test a 150 metre strike length on the west portion of the 144 Gap Zone between the 450 and 700 metre levels.

An additional 20 surface holes and two wedge holes were drilled mainly at the 144 Gap SW Zone and 144 South to advance the Company's geological model to the Southwest of the 144 Gap Zone. Results at both locations were successful and indicated similar rock types to those found at the 144 Gap Zone. In addition, results at 144 South included the identification of new zones of gold mineralization. Among the results at 144 South are 3.11 gpt/19.1 m, 5.38 gpt/3.6 m, 5.30 gpt/2.7 m and 4.22 gpt/2.7 m in Hwy-15-142, 4.27 gpt/7.3 m in Hwy-15-142W2 and 9.59 gpt/3.0 m in Hwy-15-148. Intersections from these holes are located approximately 100 to 200 metres northeast and 450 metres below previously reported results from Hwy-12-45 and Hwy-11-28 (see press release dated January 21, 2013).

Interpretation of drill results from the 144 Gap Zone continues to suggest that the zone is closely associated with a broad zone of hydrothermal alteration and deformation measuring up to 100 m wide containing multiple syenite porphyry intrusions and quartz veining, with pyrite, scheelite, galena and visible gold. Based on results received to date, the 144 Gap Zone is confirmed to have minimum strike and dip lengths of 400 m. The results from new drilling at 144 South indicate the presence of similar rock types, alteration and mineralization at distances up to 1.6 km to the southwest of the 144 Gap at elevations above the new 820 exploration drift.

Qualified Person

The Qualified Person ("QP") for Lake Shore Gold's drill program at the 144 is Eric Kallio, Senior Vice-President Exploration, P.Geo. Mr. Kallio, 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 surface 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. BQ size underground drill core is either saw cut or whole core sampled. The drill core is transported in security sealed bags for preparation to the ALS Minerals analytical facility located in Val d'Or Quebec for fire assay. This ALS Minerals facility is registered ISO 9001-2008 (CERT-0051527) and is SCC ISO/IEC 17025:2005 Accredited (#689). Most underground drill core is analyzed by Activation Laboratories Ltd. (Actlabs) in Timmins, Ontario. Actlabs is an ISO/IEC 17025:2005 Accredited laboratory.
