The Giant Mine was a large gold mine located on the Ingraham Trail just outside of Yellowknife, Northwest Territories. Gold was discovered on the property in 1935 by Johnny Baker, but the true extent of the gold deposits were not known until 1944 when a massive gold-bearing shear zone was uncovered beneath the drift-filled Baker Creek Valley. The discovery led to a massive post-war staking boom in Yellowknife. Giant Mine entered production in 1948 and ceased operations in 2004. It produced over of gold.

Die Giant Mine war eine große Goldmine nahe Yellowknife, der Hauptstadt der kanadischen Provinz Nordwest-Territorien. Bis 2004 wurden hier 220 Tonnen Gold abgebaut.
