| Lake Shore Gold Extends Casa Berardi "G Zone," Discovers New Zone on West Block and Commences New Winter Drill Program
- Mineralization in Casa Berardi East Block "G Zone" extended to 280 metres below surface with CE-09-13 intersecting 6.24 gpt over 1.00 metre and 8.56 gpt over 1.00 metre, CE-09-18 intersecting 3.04 gpt over 6.30 metres, including 5.70 gpt over 2.70 metres, and CW-09-12 intersecting 2.33 gpt over 7.30 metres, including 4.83 gpt over 1.90 metres.
- Initial program of drilling on West Block discovers new mineralization of 3.44 gpt over 3.91 metres at 375 metre depth within largely untested 150 metre wide zone of deformation and hydrothermal alteration, highlights significant potential of West Block area.
- Lake Shore Gold expects to earn 50% interest in Casa Berardi optioned property by end of 2010. |
TORONTO, ONTARIO--(Marketwire - Feb. 16, 2010) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the "Company") today reported results from 16 holes and 6,893 metres of Diamond drilling completed in 2009 at the Company's Casa Berardi optioned property. Of the 16 holes, 10 holes (3,656 metres) were completed on the east block approximately 6.0 kilometres ("kms") east of the Casa Berardi mining operations and along the east extension of the Casa Berardi fault zone. The remaining six holes and 3,237 metres were drilled on the west extension of the Casa Berardi Fault at distances between 600 metres and 1.3 kms west of the boundary with the Casa Berardi Mine.
Lake Shore Gold is currently earning a 50% interest in the Casa Berardi optioned property through an option agreement, reached in September 2007, with Aurizon Mines Ltd. ("Aurizon") by spending $5.0 million over a period not to exceed five years. As of December 31, 2009, the Company had spent approximately $3.5 million towards the earn-in commitment. Lake Shore Gold is the operator during the earn-in period. The optioned property lies to the east and west of Aurizon's wholly owned Casa Berardi mining operations, including the West Mining Complex and East Mine and Mill Complex.
Significant results from the East Block include an intercept of 2.33 gpt over 7.30 metres, including 4.83 gpt over 1.90 metres in CE-09-12, which tested the east portion of the G Zone at a depth of 280 metres below surface and 45 metres below the previously reported "new discovery" value of 8.58 gpt over 10.40 metres in CW-08-03 (see previously released press release dated October 23, 2008). Mineralization intersected is contained within an altered zone of deformed mixed lithic wacke and magnetite rich sediment bands and minor banded chert-magnetite Iron Formation in contact with a 16.30 metre thick banded chert-magnetite Iron Formation unit. This intersection confirms the continuity of the structure in CE-08-03 to depth. CE-09-18 was drilled 400 metres west of CE-09-12 to test an intersection of 6.84 gpt over 3.10 metres in the previously released CE-08-11. This hole returned 3.04 gpt over 6.30 metres, including 5.70 gpt over 2.70 metres, and extends mineralization in this area of the G-Zone to a vertical depth of 290 metres within a strike length of 500 metres.
Drilling on the West Block of claims focused on exploring a 1.0 km strike length of untested stratigraphy along the Casa Berardi Fault. CW-09-23 returned 3.44 gpt over 3.91 metres, including 6.07 gpt over 1.00 metre, at a vertical depth of 375 metres below surface. This new intersection is the most significant result from the limited drilling west of the Casa Berardi Mine Claim boundary and highlights the exploration potential for new discoveries along the Casa Berardi Fault trend. The host unit contains anomalous gold values over a 23.2 metre drill thickness and is made up of hydrothermally altered and strongly deformed graphitic and wacke bands with ribboned 20-40% quartz - ankerite veining with 5 % - 70% pyrite - pyrrhotite and minor arsenopyrite within an overall package of Chert-sulphide Iron Formation. The intersection is associated with a 150 metre wide zone of strongly deformed and altered metasediments and local Iron Formation along the west extension of the Casa Berardi Fault Zone near a major contact between mafic to intermediate volcanic and sedimentary rocks. This zone of deformation is essentially untested (nine shallow holes drilling to 100 metres below surface) for a 700 metre strike length east of Hole CW-09-26 and a further 700 metres to the west of this hole, for a total unexplored strike length of 1.4 kms.
Tony Makuch, President and CEO of Lake Shore Gold, commented: "Casa Berardi represents an important opportunity for future growth for Lake Shore Gold, one that will move the Company beyond its strong foundation in the Timmins Camp. We are very encouraged by the extension to depth of the East Block and the new zone discovered on the optioned property to the west of Aurizon's Casa Berardi mining and milling operations. Given the continuity of structures illustrated to date and large untested gaps within these structures, we are encouraged by the potential to define new resources in close proximity to the Casa Berardi mill. In the West Block, CW-09-23 intersected a strongly deformed, broad zone of alteration and mineralization within the same trend as the Casa Berardi mining operations. Future drilling will test the intersections along strike and at depth in order to determine the attitude and plunge of the mineralized structure. We are looking forward to earning our 50% interest before the end of the year and to moving the property forward as a 50% joint venture partner with Aurizon."
The 2010 drill program will include approximately 10,700 metres of Diamond drilling on both the East and West blocks and includes both summer and winter drilling. Expenditures related to the 2010 program are expected to allow the Company to earn its 50% interest in the Casa Berardi operation property before the end of 2010. The winter program is scheduled to start on or about February 15, 2010 and will include a total of approximately 6,000 metres in 23 holes designed to illustrate continuity and expand mineralization in the G Zone.
Quality Control
The Company's Qualified Person ("QP") for the Casa Berardi property is Keith Green, 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 to ALS Chemex Lab located in Val'dor, Quebec for analysis.. ALS Chemex is an ISO 9001-2000 registered laboratory preparing for ISO 17025 certification.
