Blakelock – Little Abitibi

Lake Shore´s 100% owned Blakelock property is located 140 kilometres northeast of Timmins and covers an area of 35 kilometres along the western extension of the Casa Berardi gold belt. The Little Abitibi property was acquired based on geophysical surveys conducted by the Company in 2006. The property covers an additional 20 kilometres of the projected Casa Berardi structure west of the Blakelock property.

An extensive reverse circulation (“RC”) drill program was conducted during the first quarter of 2007 with two RC drills. The program consisted of a total of 90 RC holes primarily located on the western part of the Blakelock property. RC samples were collected from the overburden till cover and from the bedrock. This method is widely utilized in areas with extensive overburden cover in the Canadian Shield to further define diamond drill targets. Samples collected from this program were analyzed for their gold grain content and shape in an attempt to determine proximity to the in situ source of any gold mineralization to the north, in the up-ice direction. In total, three separate drill holes contained pristine gold grain counts.

A 10-hole diamond drill program was completed during the second half of 2007 on the Blakelock property, for a total of 3,151 metres. The primary focus of this drilling program was to follow up on the results obtained during the RC program. To date no significant gold assays have been identified, however several areas of interest were identified based on visual assessment of structure, mineralization, veining and alteration during the core logging process. Further assessment of these areas using the ICP assaying data will be carried out to develop a solid framework for further exploration activity.

During the fourth quarter of 2007, five diamond drill holes for a total depth of 1,255 metres were completed on the Little Abitibi property. The intent of the drilling program was to identify geologically favourable environments associated with the western portion of the Casa-Berardi fault zone in which gold bearing zones/structures may occur. Drilling targeted magnetic anomalies occurring along the above mentioned Casa-Berardi fault. The Little Abitibi property represents the western most portion of Lake Shore Gold´s land holdings along the Casa-Berardi fault structure.

An extensive reverse circulation (“RC”) drill program was conducted during the first quarter of 2008, including drilling of 59 RC holes primarily located on the central part of the Blakelock property. RC samples were collected from the overburden till cover and from the bedrock. This method is widely utilized in areas with extensive overburden cover in the Canadian Shield to further define diamond drill targets. No significant gold anomalies have been identified from till samples collected during this program.

Work in the second half of 2008 included mobilization of a diamond drill to the Porphyry creek area of the property and commencement of a 7 hole 2,825 metre drill program. The drilling was designed to test a hydrothermally altered sequence of volcanic rocks and felsic intrusive located immediately north of the Casa Berardi Break and surrounding previous interesting drill results obtained by Lake Shore Gold in 2006. Results from this work were received in the first half of 2009. The drilling obtained interesting alteration but mostly low grade assay values. Future plans for exploration on the property are still being reviewed.
