Blakelock
Lake Shore’s 100% owned Blakelock Property covers approximately 30 kilometres of the western projection of the Casa Berardi Fault. The Property comprises claims staked in Blakelock, Hoblitzell, Tweed, Bragg and Neman Townships, 140 kilometres northeast of Timmins, Ontario. Provincial road 652 passes through the west portion of the Property.
The Blakelock Property is in the northern Abitibi Greenstone Belt, 58 kilometres west of the Casa Berardi Gold Mine (about 3 million ounces production plus reserves), and 60 kilometres southwest of the Detour Lake Gold Mine (1.7 million ounces production). It is located on the western projection of the Casa Berardi Fault, north of the Tomlinson tonalite pluton. A contact between felsic to mafic volcanics and sedimentary rocks with intercalated banded iron formation trends east-west across the Property. Numerous quartz-feldspar porphyry dykes and plugs have intruded along this contact in the Blakelock area.
Past exploration in Blakelock Township was spurred on by the discovery of gold at Detour Lake in 1974 by Amoco Canada, and at Casa Berardi in 1981 by Inco Limited. Esso Minerals conducted a major regional exploration program in 1985-1988, which included airborne magnetic, EM, resistivity and IP surveys, and reverse circulation and diamond drilling. Esso drilled a total of 14 RC holes and 19 diamond drill holes on what is now Lake Shore’s Blakelock Property.
Esso discovered a significant zone of high-grade gold-silver mineralization associated with an intensely sericitized, quartz veined and mineralized quartz-feldspar porphyry intrusion. Gold-silver mineralization was identified over a 430 x 250 metre area:

Mineralization is associated with mylonitic shear zones and quartz veins with up to 5% sulphides, including pyrite, sphalerite, galena, molybdenite, chalcopyrite, as well as hessite, native bismuth and native gold.
