Timmins hat goldenen BODEN wieder LSG MAR 4, 2011 - 08:43 ET Lake Shore Gold Reports Wide Intersections With High-Grade Sections Within Porphyry Zone at Thunder Creek, Underground and Surface Drilling Highlight Potential to Expand Mineralized System - Underground drilling from east edge of Porphyry Zone near 730 Level intersects 75.14 gpt over 18.60, including 284.19 gpt over 4.60m, and 3.30 gpt over 76.70m within broader intercept grading 11.53 gpt over 147.30m, new hole drilled nearly perpendicular to discovery hole TC-09-68B (12.75 gpt over 83.40m) - Surface drilling in untested area near west edge of deposit intersects 5.92 gpt over 9.90m and 4.67 gpt over 6.40m, potential to extend mineralization to west and towards surface of new intersections considered excellent - Hanging wall drifts being developed to support deep drilling planned for later in 2011 TORONTO, ONTARIO--(Marketwire - March 4, 2011) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the "Company") today announced results from 6 drill holes (3,035 metres) from the 730 Level at the Thunder Creek Project with 4 holes (1,060 metres) being collared underground and 2 holes (1,975 metres) on surface. The holes are part of a continuing drill program to define the overall geometry and grade of the Porphyry and Rusk Zones near the 730 elevation in order to complete an initial National Instrument 43-101 compliant resource estimate. Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's results are very exciting as they provide confirmation that we are dealing with a very special gold deposit at Thunder Creek which is already meeting and exceeding our original expectations in terms of size and grades. With today's drill holes we have now recorded very wide intersections with high-grade sections from multiple directions. Given the location of some of the intercepts they also demonstrate the potential to expand the zones, which supports our belief that what we may have is one very large mineralized system that runs along the Timmins Mine, Thunder Creek and 144 trend. We are continuing our aggressive drill program at Thunder Creek with five drills currently active in support of our efforts to establish an initial National Instrument 43-101 resource later this year. In addition, we are also developing two hanging wall drifts and will use these drifts to drill for extensions between the 300 and 730 levels and to a depth of 1,500 metres. The potential to extend the mineralization to depth is excellent as both the Rusk and Porphyry zones remain open and the size of the porphyry stock increases the deeper it goes." Three of the new holes drilled from underground (730-005,730-008 and 730-009) were collared near the east edge of the Porphyry Zone and one hole (650-004b) was collared on the west side of the new access drift from the Timmins Mine. Significant results from the new holes collared east of the zones are 75.14 gpt over 18.60m, including 284.19 gpt over 4.60m, and 3.30 gpt over 76.70m within a broader intercept of 11.53 gpt over 147.30m. 730-005 and 730-009 were drilled in a westerly direction at horizontal and minus 25 degree angles, respectively, and 730-008 was drilled at a horizontal angle in a southerly direction. The midpoint of the new intersection in 730-009 is approximately 12 metres below the intersection in TC-09-68B, with the two holes being nearly perpendicular in direction. TC-09-68B was the original discovery hole for the Porphyry Zone and graded 12.75 gpt over 83.40m (see press release dated June 24, 2009). Results from 650-004b, which was drilled from the same cut out as the previously reported underground hole 650-001, which intersected 4.91 gpt over 99.60m (see press release dated November 24, 2010) were also positive and included 3.11 gpt over 95.70m. 650-004b passed approximately 25 metres below 650-001 and strongly confirms the drill results from that initial underground hole. Observations to date indicate that mineralization near the 730 Level occurs within a broad envelope containing lenses of higher grade material throughout. The overall envelope covers the entire width of the Rusk and Porphyry zones and measures approximately 175 metres long and 100 metres wide. High grade material in the Porphyry Zone seems closely associated with swarms of quartz veining along with local visible gold, while high grades in the Rusk Zone are associated with strongly folded, altered and pyritic zones of pyroxenite. Of interest, drilling from the 730 level has now been completed across the mineralized envelope in a variety of directions and obtained high grades over significant widths from each. Significant results from surface drilling included 5.92 gpt over 9.90m in TC09-69h and 4.67 gpt over 6.40m in TC09-69j from the Rusk Zone. These holes were drilled near the present west limit of the Rusk Zone, approximately 100 metres above the 730 Level and continue to show strong potential to expand the zone in this direction. Drilling is continuing at the Thunder Creek project with 5 drills, including two drills near the 300 Level, two drills near the 730 Level and one drill on surface. Work is also continuing with the development of hanging wall drifts on the 300 and 730 levels in order to allow better drill coverage in areas between the 300 and 730 levels and to an eventual depth of 1,500 metres. The deepest holes to test the zone to date are at a vertical depth of 1,000 metres and indicate the Rusk and Porphyry zones are open to depth and that the Porphyry stock hosting the Porphyry zone is increasing in size. -----------
