ABSTRACT
Gold has been mined in every Canadian province. Lode gold mines account for 66 per cent of gold output and, apart from a few alluvial operations, the remainder is produced as a by-product of base-metal ores. Canadian gold deposits appear to have a close relationship with belts of Archean volcanic rocks. The ‘gold belt’ that runs across northern Ontario and into northern Quebec from west of the Manitoba-Ontario border is the major source of gold, with the three main areas, Porcupine (Timmins), the Kirkland Lake-Larder Lake area and Red Lake about to be increased to four when the Detour Lake development begins operation.
