Lake Shore Gold Reports Encouraging Results from 144 Property

Lake Shore Gold Corp. (TSX:LSG) today announced very encouraging results from the first 12 holes of drilling at the Company's 144 property.

  • Drill results confirm presence of large mineralized system with strong similarities to Thunder Creek Rusk and Porphyry zones with multiple occurrences of visible gold

  • Significant gold values intersected within 200 metres of surface, compare favourably to Thunder Creek mineralization at similar shallow depths

  • Grades and widths of mineralization increasing with depth, potential for new zones to north and along strike considered excellent

    • Among significant intersections are 2.41 grams per tonne ("gpt") over 19.00 metres ("m"), including 6.61 gpt over 2.20m, 4.96 gpt over 5.40m, including 15.18 gpt over 1.45m, 4.03 gpt over 5.10m, including 7.02 gpt over 2.40m, and 1.16 gpt over 32.20m, including 3.20 gpt over 6.20m

  • Drilling up to 800 metres along strike to southwest intersects additional alteration, deformation and gold values in possible faulted offset of new discovery zone, represents large area for potential extensions and additional new discoveries  

The 144 property is located immediately to the south of the Thunder Creek project and covers the projected southwest extension of alteration and deformation from Thunder Creek. The new holes being announced cover a broad strike length of approximately 1.2 kilometres and represent a first, high-level phase of testing designed to cover the area on a wide-spaced pattern in order to develop an improved geologic model. The results demonstrate that the overall gold bearing potential of the 144 property is excellent.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "We are extremely pleased with the results from our first drill holes at the 144 property, which establish the property as a new major project for the Company. The new discovery at 144 supports our theory that with projects like Timmins Mine, Thunder Creek, Gold River Trend and now 144, our Timmins West Complex represents the western extension of the Timmins Gold Camp and is, in actuality, one very large mineralized system with the potential to support large-scale mining for a very long time to come. The initial drill results from 144 show strong similarities in geological setting and are in close proximity to Thunder Creek. Given the shallow depth of intersections and dimensions of the geological structures observed to date the new discovery compares very favourably to the Thunder Creek mineralization at similar depths and we look forward to continuing exploration drilling in this area with three drills currently operating and at least one additional drill to be added."

Seven of the new holes being announced (Hwy-10-02, 03, 05, 07, 09, 11 and 12) were drilled to test a 200 metre strike length along the projected southwest extension of the Thunder Creek Alteration and Deformation Zone ("TDAZ"), approximately 1.2 kms from Thunder Creek. The program was successful in confirming the presence of a significant mineralized system extending over the entire area with strong similarities to the Thunder Creek mineralization. Significant results from the new drilling are 2.41 gpt over 19.00m, including 6.61 gpt over 2.20m, 4.96 gpt over 5.40m, including 15.18 gpt over 1.45m, and 14.42 gpt over 0.95m in Hwy-11-12; 5.58 gpt over 1.00m, 11.75 gpt over 0.30m, 9.08 gpt over 0.30m and 3.58 gpt over 1.40m in Hwy-10-03; 4.03 gpt over 5.10m, including 7.02 gpt over 2.40m and 4.87 gpt over 1.50m, in Hwy-11-11; and 1.16 gpt over 32.20m, including 3.20 gpt over 6.20m, 11.05 gpt over 0.50m and 16.75 gpt over 0.30m in Hwy-10-02.

The new intersections were obtained near the south margin of a large Syenite stock which intrudes a sequence of mafic volcanics and pyroxenitic rocks near a distinct northwest trending flexure of the TDAZ. Gold mineralization occurs in multiple zones which trend northeast-southwest and dip moderately to the northwest, with the strongest mineralization being closely associated with increased levels of alteration, quartz veining, coarse pyrite as well as local galena and visible gold. The bulk of the mineralization identified to date is located at depths of less than 200 metres and follows a similar pattern to Thunder Creek where grades and widths are increasing with depth. Due to strong folding near the north side of the flexure it appears that the north-east extension of the mineralization from the flexure lies south of the closest holes drilled and remains open towards Thunder Creek.

In addition to the above, five holes were drilled to test the area southwest of the new discovery zone for possible expansion potential. Holes Hwy-10-01 and Hwy-10-04 were drilled approximately 175 metres southwest of Hwy-10-09 and Hwy-10-02 and intersected a diabase dike near the projected extension of the zones, along with several small lenses of porphyry and low gold values. Based on the above, it is possible that portions of the zone may have been faulted off along the edge of the dike.

Hwy-10-06 and Hwy-10-10 tested 500 and 800 metres, respectively, to the southwest of Hwy-10-01 and identified alteration and mineralization in a northeast trending zone which appears to be the extension of the zone to the north, but offset along a major north south fault marked by diabase. Key intersections include 8.48 gpt over 1.20m in Hwy-10-06 and 3.49 gpt over 1.75m and 4.68 gpt over 0.60m within a broad envelope grading 0.67 gpt over 29.35m in Hwy-10-10. Observations from both holes indicate similar carbonate alteration, lenses of syenite and coarse pyrite and local visible gold as in holes to the north. Given the lack of testing between the two holes or along strike to the north and to depth the potential for new mineralization is considered excellent.

Drilling is continuing at the 144 property with 3 drills but plans are in progress to increase this number to at least 4 drills within the coming months. The overall objective is to drill approximately 50,000 metres at the 144 property in 2011 with the main focus being to identify and evaluate new resource potential southwest of Thunder Creek.

Quality Control

The Company's Qualified Person ("QP") for the ongoing surface drill program at the 144 property is Jacques Samson, P.Geo. As QP, Mr. Samson has prepared or supervised the preparation of the scientific or technical information for the property and has verified the data disclosed in this press release. Mr. Samson 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. 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. Drill core samples are transported in security-sealed bags to ALS Chemex's Timmins Sample Preparation Facility. Sample preparation is completed in Timmins and the prepared sample pulps are then transported to ALS Chemex's analytical laboratory in Val d'Or, Quebec and less commonly to the Vancouver, BC Lab. Gold grades are obtained on all samples via Fire Assay with Atomic Absorption finish, using 30g aliquots. For samples that return a gold content greater than 3.0 gpt, the sample is re-analyzed via Fire Assay with Gravimetric finish. ALS Chemex is an ISO 9001-200 and ISO 17025 certified laboratory.
