Lake Shore Gold, a subsidiary of Pan American Silver’s Timmins West Mine (TWM), is an underground gold mine located 18 kilometres west of Timmins, Ontario. The TWM includes three gold deposits: the Timmins Deposit, the Thunder Creek Deposit, and the 144 Gap Deposit. The primary access to the underground workings is via a concrete-lined shaft and a portal/ramp from surface. The primary mining methods include transverse and longitudinal longhole stoping. Stopes are backfilled using both pastefill and unconsolidated development waste. Ore is hoisted to surface via shaft and by truck to the ore stockpile, where it is loaded into over-the-road trucks for haulage to the Bell Creek mill, located 56 kilometres away from TWM. Safety is the golden priority at TWM and is fundamental to what they do. The mine strives for continuous improvement and that their safety strategy is maintained as a core value of their operation.
