Giant Mine
From Wikipedia, the free encyclopedia
The Giant Mine was a large gold mine located at 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 dift-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 7 million troy ounces (220,000 kg) of gold.
On September 18, 1992, at the height of a labour dispute, an explosion in the mine shaft of Giant Mine killed nine replacement workers. Mine employee Roger Warren was later convicted of placing the bomb. The strike ended in 1993.
Owners of the mine have included Falconbridge (1948-1986 through subsidiary Giant Yellowknife Mines Limited), Pamour of Australia (1986-1990 through subsidiary Giant Yellowknife Mines Limited), Royal Oak Mines Incorporated (1990-1999), and Miramar Mining Corporation (1999-2004).
The Northwest Territories' first mining museum is to be built on the old property. The N.W.T. Mining Heritage Society is in charge of the work.
[edit] Contamination
Mining operations over four decades created a massive environmental liability, a problem which the mine's previous owners left to the Canadian and Northwest Territories governments to sort out. The Giant mine contains 237,000 tonnes of arsenic trioxide dust.[1] A $200 million taxpayer-funded remediation project is underway. The proposed solution is to permanently freeze the arsenic trioxide storage chambers to keep groundwater seepage out.[2]
[edit] Film
The events and aftermath of the Giant Mine labour dispute and explosion were dramatized in the 1996 CBC television movie Giant Mine.
