Lake Shore Gold Announces 19.55 g/t Over 6.00 Metres and Discovery of Second Mineralized Horizon in Porphyry at Thunder Creek
- 8.86 g/t Au over 24.85 m, including 10.88 g/t Au over 4.05 m, 19.55 g/t over 6.00 m, 7.95 g/t Au over 5.25 m in hole TC09-69 - Rusk Zone extended 775 m below surface; remains open at depth - Second gold zone indentified within Porphyry; Porphyry Zone returns gold mineralization over 122 m
Lake Shore Gold Corp. (TSX: LSG) ("Lake Shore Gold" or the "Company") today announced the release of new, high-grade intercepts from six additional holes (4,093 metres) as part of its ongoing 22,000 metre diamond drill program on the Company's Thunder Creek property, which is located immediately adjacent to Lake Shore Gold's 100%-owned Timmins Mine project.
The Company is the operator of Thunder Creek joint venture with a 60% interest in the property. The results include an intercept of 8.86 g/t Au over 24.85 m, including 10.88 g/t Au over 4.05 m, 19.55 g/t Au over 6.00 m and 7.95 g/t Au over 5.25 m in Hole TC09-69, and 7.41 g/t Au over 3.00 m, 5.80 g/t Au over 13.65 m and 5.29 g/t Au over 12.85 m in Hole TC09-68. These intercepts extend the Rusk and Porphyry zones at Thunder Creek by 200 metres at depth and 100 metres along strike, for a total depth of approximately 775 metres. They also indicate the presence of a second significant mineralized horizon within the Porphyry zone. The zones remain open at depth and along strike.
Hole TC09-68 and 69 were designed to test the downward extension of the Rusk and Porphyry zones below the previously announced Hole TC08-54 (see press release dated December 16, 2008), which had been the deepest intercept at 575 m and was the first to be identified within a new porphyry-hosted mineralized system. Included within TC08-54 was a high-grade zone of 25.99 g/t Au over 3.00 m within a broader zone averaging 5.90 g/t au over 26.35 m. Based on the results of TC09-68 and TC09-69, the overall thickness of the Syenite porphyry has increased from approximately 30 m in Hole TC08-54 to over 120 m in Hole TC09-69 and there are at least two significant horizons of mineralization within the Porphyry extending to depth. Mineralization in the Porphyry zone continues to indicate a strong association with quartz veining, increased pyrite and VG (visible gold) with minor scheelite, sphalerite, galena, molybdenite and tellurides.
Tony Makuch, President and CEO of Lake Shore Gold, commented: "The results being announced today are extremely encouraging. In the tradition of Timmins gold deposits, we are seeing that the mineralized system within the porphyry is running to depth and, equally important, is widening as it deepens. In addition, the discovery of multiple horizons greatly enhances the potential of each drill hole to encounter mineralization and to add meaningfully to the size and resource potential of the project. Today's results also highlight the significant potential of the historically un-mined portion of Timmins gold camp lying west of the Mattagami River Fault, an area that we believe represents an important new chapter to this legendary mining camp."
In August of 2008, Lake Shore Gold announced the beginning of a 22,000 metre diamond drilling program on the Thunder Creek property. The program was designed to be carried-out intermittently with one to two drill rigs, and will extend to approximately mid-2009. There are currently two drills working on the property. A total of 10,995 metres in 19 holes have been completed, with results from the first nine holes (4,000 metres) having been released in a press release on December 16, 2008 and an additional six holes (4,093 metres) being announced in today's press release. Four additional holes plus wedge holes TC-09-68a and TC09-69a and portions of holes TC09-68 and TC09-69 above and below the Rusk and Porphyry Zones are still in the process of being sampled and assayed and two additional holes, TC09-70 and TC09-71, are still in progress drilling. TC09-70 is testing the area 100 metres to the east of TC09-68 and TC09-71 is testing approximately 125 metres west of TC09-69.

Based on data collected to date, the Rusk Gold Zone appears to represent a high-grade shoot within a broad north-east trending mineralized corridor, steeply dipping to the northwest. This shoot lies along the contact between the Alkalic Intrusive Complex and sediments located in the footwall to the intrusive. It is characterized by very strong alteration and deformation, accompanied by numerous ultramafic to felsic dykes, quartz-ankerite veining, and sulphide mineralization. Significant intercepts below the 200 metre level, previously reported by the Company, within this Zone include: 10.91 g/t Au over 3.65 m (TC07-30), 8.57 g/t au over 9.00 m (TC07-43) and up to 24.61 g/t au over 7.0 m (TC07-36).
Among other holes reported today, TC08-60 and 64 intersected the Rusk Horizon between 400 and 500 m below surface. Hole TC08-60 intersected three zones averaging 5.55 g/t Au over 2.40 m, 5.50 g/t Au over 5.80 m and 4.24 g/t Au over 4.55 m, within a wider interval which averages 3.48 g/t Au over 21.15 m. The intercepts include high grade hits up to 13.33 g/t Au over 0.65 m, 15.00 g/t Au over 0.60 m and 25.50 g/t Au over 0.35 m. Hole TC08-64, located about 50m below TC07-41 (8.52 g/t Au over 2.05 m --see press release dated March 31, 2008), roughly 80m vertically below hole TC08-60, intersected 3.02 g/t Au over 11.05 m, including 6.81 g/t Au over 3.35 m, 12.80 g/t Au over 0.50 m and 12.10 g/t Au over 0.40 m.
TC08-61 and TC08-62 tested the Rusk Horizon at less than 150m below surface and did not obtained significant results, though it is believed that given uncertainties regarding the plunge in this area the holes may have passed over the projected plunge line for the high grade shoot.
The Thunder Creek property is a joint venture, with Lake Shore Gold owning a 60% interest and acting as project operator, with the remaining 40% interest owned by West Timmins Mining Inc.
Quality Control
The Company's Qualified Person ("QP") for the Thunder Creek property is Jacques Samson, P. Geo. As QP, he 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. Lake Shore Gold has a quality control program to ensure best practices in the sampling and analysis of drill core. Assays have been completed using a standard fire assay with a 30-gram aliquot. For samples that return a value greater than three grams per tonne gold, another pulp is taken and fire assayed with a gravimetric finish. 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 Chemex Prep Lab located in Timmins, Ontario, and the pulps shipped to ALS Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO 9001-2000 registered laboratory preparing for ISO 17025 certification.
