Work commenced on new National Instrument ("NI") 43-101 report for update to mineral resources, completion planned for first quarter of 2012
Lake Shore Gold Corp. today announced results from an additional 45 holes (6 abandoned) in 18,965 metres of drilling completed as part of the 2011 drill program at the Company's 100 percent owned Thorne property, which overlies the Gold River Trend. The Gold River Trend is a major alteration and deformation structure, located approximately 3 km south of the Company's Thunder Creek deposit which has been traced for a minimum strike length of 3.5 kilometres. Current NI 43-101 compliant inferred resources at the property are listed at approximately 4 million tonnes, grading approximately 3.00 gpt (400,000 ounces). The current drill program is focused on the Gold River East area and is designed to infill and expand previously defined zones in preparation for a new NI 43-101 resource update scheduled for the first quarter of 2012.
Tony Makuch, President and CEO of Lake Shore Gold, commented: "Today's results continue to demonstrate the strong exploration potential of the Gold River Trend and its ability to contribute substantial new resources to our portfolio. As a result of recent drilling, the mineralization has been confirmed near surface, with widths and grades which are similar or better than obtained by previous operators, and has also been successfully extended along strike and to a depth of 850 metres, with the mineralization remaining open. Based on drill results to date, we have excellent potential to add new open pit and shallow depth underground resources which will greatly enhance our growth strategy in the Timmins area. We look forward to completing our 2011 drill program and to updating our NI 43-101 resource by early next year."
Drilling included 24 holes designed to test the North Porphyry/4800 Zone both near surface and to depth. Ten (10) of the new holes in this area targeted a 350 metre strike length of the Zone between 400 and 840 metres below surface. Results of the program were very successful and indicated the downward continuation of a broad envelope of strong hydrothermal alteration measuring up to 150 metres wide, as well as the presence of multiple high-grade structures extending to a minimum 840 metres below surface and 450 metres below the current resource. Among significant results are 4.22 gpt over 16.00m, 72.84 gpt over 1.60m, including 116.50m over 1.00m and 27.30 gpt over 1.00m in TH-11-65A, 8.80 gpt over 5.60m, including 16.09 gpt over 2.80m, 11.39 gpt over 1.50m, 11.45 gpt over 0.50m in TH-11-65B, 9.64 gpt over 1.90m, 7.39 gpt over 3.00m and 3.13 gpt over 1.60m in TH-11-75A, 10.59 gpt over 1.50m in TH-11-80, 7.68gpt over 4.50m in TH-11-98 and 3.26 gpt over 2.45m and 3.50 gpt over 2.90m in TH-11- 94A.
Another 14 holes at the North Porphyry/4800 Zone were designed to infill and expand mineralization near surface and between existing resource blocks. As with deeper drilling, the results were very successful and indicated a combination of broad zones containing multiple higher-grade structures. Significant intersections are 254.00 gpt over 1.60m, including 1,350.00 gpt over 0.30m in TH-11-113, 11.63 gpt over 2.30m in TH-11-92, 1.58 gpt over 18.30m, including 6.00 gpt over 3.20m in TH-11-87, 2.10 gpt over 10.30m, including 11.26 gpt over 1.30m in TH- 11-76, 1.84 gpt over 7.60m and 10.70 gpt over 1.00m in TH-11-77 and 10.30 gpt over 1.30m in TH-11-72.
Drilling also included eight exploratory holes to test areas up to 300 metres east of the current NI 43-101 resource where little previous drilling had been completed. Results of the drilling were very positive and intersected favourable structure and alteration at shallow depths with key intersects including 1.87 gpt over 17.75m, including 18.93 gpt over 1.20m and 7.64 gpt over 1.60m in TH-11-96, 2.04 gpt over 19.80m, including 9.55 gpt over 1.00m and 7.82 gpt over 2.50m in TH-11-85. Current interpretations suggest the mineralized zones in the new holes line up well with those in the resource blocks and represent a 300 metre extension of the Gold River East trend. The structure remains open to the east and on LSG ground for a minimum of 1.8 kms, as well as to depth.
Six holes were also completed in the Kapika Zone and Fold Nose areas. The two holes on the Kapika Zone were designed to test mineralization 350 metre northwest of the Fold Nose resource and within 200 metres of surface. These holes continued to show positive results. Among key intersections in the Kapika Zone are 2.34 gpt over 20.40m, including 4.15 gpt over 8.40m, 13.25 gpt over 0.90m in TH-11-101, as well as 4.86 gpt over 8.50m, including 11.28 gpt over 3.00m and 13.40 gpt over 3.20m in TH-11-100. Intersections in the Fold Nose area include 1.54 gpt over 13.20m in TH-11-105 and 1.17 gpt over 16.0m in TH-11-103.
Drilling is continuing at the Gold River East area with 2 surface drills doing a combination of infill and expansion drilling. Preliminary work has also been initiated on the new NI 43-101 report.
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. 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. Assays have been completed using a standard fire assay with a 30-gram aliquot. For samples that return a value greater than ten grams per tonne gold, the sample is 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.
