The Sandridge Project is located approximately 150 kilometres east of Thunder Bay, Ontario. Sandridge is hosted in the Winston Lake Greenstone Belt (“WLGB”) within the northern part of the Wawa terrane of the Archean-age Superior province. It is characterized by mafic to felsic volcanic and siliciclastic sedimentary rocks, collectively intruded by tonalite-trondhjemite-granodiorite and gabbroic stocks.
The WLGB hosts three past-producing mines: Zenith, Winston Lake and Pick Lake. Approximately 180,000 tons at 16.6 per cent zinc was mined at the Zenith mine between 1966 and 1970. Past production at the Winston Lake mine was approximately three million tons at 14.1 per cent Zn and 1.0 per cent copper. Past production at the Pick Lake mine was 172,956 tons at 9.9 per cent Zn and 0.7 per cent Cu. Mining operations at Winston Lake and Pick Lake ceased in 1998 due to poor metal prices. All three deposits are classified as bimodal-mafic volcanic-hosted massive sulphide-type. Historical geophysical and geochemical data suggest that the favourable WLGB stratigraphy hosting the Winston Lake and Pick Lake deposits extends northwest into the Sandridge project area.
Sandridge is located approximately eight kilometers northwest of the former Winston Lake mine, where a substantial infrastructure is in place. Sandridge consists of a block of 18 contiguous single-cell mining claims totaling 378 hectares covering VTEM conductors on regional strike with the Winston Lake and Pick Lake deposits. The company regards conductors within the project prospective in part because of their favourable regional setting. Golden Share considers Sandridge a drill-ready project and has received the Exploration Permit in July 2019.
