Lake Shore Gold Corp. (TSX:LSG) today announced a number of wide, high-grade intercepts from an additional 42 holes (15,159 metres) completed as part of the 2010 drill program at the Company's 100 percent owned Thorne property along the Gold River Trend.
- Wide, high-grade intercepts reported near surface in west portion of Gold River East, potential for multiple zones confirmed
- 5.04 gpt over 16.60m intersected 35 metres below surface within broader envelope grading 2.18 gpt over 45.00m. Among other intercepts are 11.78 gpt over 1.70m, 6.64 gpt over 2.3m, 11.85 gpt over 2.50m, 7.05 gpt over 2.10m, 21.80 gpt over 0.50m, 14.90 gpt over 0.50m and 5.02 gpt over 1.40m
- Drilling on east portion of Gold River East intersects shallow, high-grade mineralization, potential for further expansion on strike and to depth considered excellent
- 5.09 gpt over 10.20m intersected at 165 metre elevation, including 7.64 gpt over 6.40m, 7.19 gpt over 2.00m and 19.85 gpt over 0.40m, with visible gold ("VG"). Among other intercepts are 8.92 gpt over 3.30m, 44.42 gpt over 1.70m, 5.89 gpt over 9.70m, including 10.48 gpt over 3.40m, 20.73 gpt over 1.50m, 15.90 gpt over 0.55m and 15.35 gpt over 0.50m
- Drilling to depth extends zones to minimum vertical depth of 750 metres from surface
- Among key intercepts are 8.74 gpt over 5.90m, including 25.23 gpt over 1.80m, 5.36 gpt over 10.40m, including 9.06 gpt over 3.00m and 9.31 gpt over 2.40m, and 26.90 gpt over 2.00m
- Revised interpretation and mineralization model based on current drilling suggests substantial near surface exploration potential along Gold River Trend, largely in shallow underground and/or open-pit zones.
The program is focused on the Gold River East Zone, which occupies a 1.5 km strike length of the Gold River Trend. The intersections reported today both confirm the potential for shallow high-grade resources amenable to open-pit and/or shallow underground mining and extend the mineralized zones at Gold River East to a minimum 750 metre vertical depth. The Gold River Trend is a major alteration and deformation structure, located approximately 3 km south of the Company's Thunder Creek deposit with a minimum strike length of approximately 3.5 kilometres. Current National Instrument ("NI") 43-101 compliant inferred resources for the Gold River Trend include 4,154,096 tonnes grading 3.33 gpt for a total of 444,471 ounces.
Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's results strongly demonstrate the potential for the Gold River Trend to host substantial new resources in shallow underground and/or open-pit zones. The Gold River Trend property, when combined with our adjacent 144 property, covers an area totaling 49 square kilometres in close proximity to our Timmins Mine and Thunder Creek deposits. These two properties are highly prospective land positions with "game changing" potential for our mining and development plans within the Timmins West Complex. We look forward to starting on the next phase of drilling at Gold River East in mid-January to evaluate additional extensions to the zones as well to start infill drilling of the mineralized envelope in preparation for an updated NI 43-101 resource over the next 12 months."
Significant results announced today include 18 holes (4,771 metres) from the West portion of the Gold River East Zone which were designed to test areas between and along strike of the Fold Nose and Kapika Zones. TH-10-62 was collared near the west edge of the Kapika zone and intersected 5.04 gpt over 16.60m within a broad envelope grading 2.18 gpt over 45.00m. TH-10-048 was drilled 140 metres to the east of TH-10-62 and immediately west of the Fold Nose Resource and intersected 11.78 gpt over 1.70m and 6.64 gpt over 2.30m. TH-10-42 was collared 220 metres east of TH-10-62 and intersected 11.85 gpt over 2.50m and 7.05 gpt over 2.10m and TH-10-35 was collared 40 metres west of TH-10-42 and intersected 21.80 gpt over 0.50m, 14.90 gpt over 0.50m and 5.02 gpt over 1.40m. As all areas tested are still open to depth and along strike the potential for further expansion is considered excellent.
Also included are 24 holes (10,388 metres) which tested the east portion of the Gold River Trend near the 4800 and North Porphyry zones along strike and to depth of previously reported drill results and historic resource blocks. Portions of the drilling were designed to test at shallow depths to confirm historic drill intercepts and along direct extensions of the current NI 43-101 compliant resource for this area. Other portions of the drilling were widely spaced step out holes to depth to gain a broader perspective of geological structure.
Among significant results from the drilling at shallow depths are 5.09 gpt over 10.20m, including 7.64 gpt over 6.40m and 7.19 gpt over 2.00m in TH-10-52, 8.92 gpt over 3.30m in TH-10-57, 44.42 gpt over 1.70m in TH-10-30, 5.89 gpt over 9.70m, including 10.48 gpt over 3.40m, in TH-10-47 and 20.73 gpt over 1.50m, 15.90 gpt over 0.55m and 15.35 gpt over 0.50m in TH-10-41. The results from these holes, together with other previously released results, are important as they strongly confirm the presence of multiple higher grade zones at shallow depths extending over the entire strike length between the North Porphyry and 4800 resource blocks.
Significant results from the deep step out holes are 8.74 gpt over 5.90m, including 25.23 gpt over 1.80m in TH-10-26B, 5.36 gpt over 10.40m, including 9.06 gpt over 3.00m and 9.31 gpt over 2.40m, in TH-10-65, 26.90 gpt over 2.00m in TH-10-53 and 5.93 gpt over 2.00m in TH-10-26C. These holes were drilled into the area underlying the North Porphyry and 4800 Zones and strongly confirm the extension of key mineralized structures in the Gold River East area to a minimum depth of 750 metres from surface. TH-10-26B and TH-10-26C were drilled as wedge cuts from previously released TH-10-26, which intersected 13.06 gpt over 8.50m (See press release dated June 23, 2010). TH-10-65 intersected mineralization 40 metres to the east of TH-10-26 and TH-10-53 intersected the structures 205 metres to the east of TH-10-26.
Based on the new dill results, a revised mineralization model has been constructed for the Gold River Trend which extends to a vertical depth of 750 metres below surface. The model demonstrates that substantial near surface resource potential exists along the Gold River Trend, particularly at Gold River East in zones amenable to open pit and/or shallow underground mining methods.
The 2010 drill program was completed midway through December 2010 and is set to re-commence in the second week of January. The program for 2011 will consist of approximately 20,000 metres of drilling and focus on infill and expansion drilling of the Gold River East area with a view to completing a new NI 43-101 resource for the property within the next 12 months.
Quality Control
The Qualified Person ("QP") for Lake Shore Gold's drill program at the Thorne Property is Jacques Samson, P.Geo. who as 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. The QP for the Company's resource estimates is Bob Kusins, P.Geo., the Chief Resource Geologist for the Company. Both Mr. Samson and Mr. Kusins are employees 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. 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.
