The story
Placer Dome was formed in Vancouver in 1987, by amalgamating Placer Development Ltd. of Vancouver (founded in British Columbia in 1926), Dome Mines Limited of Toronto (founded in Ontario in 1910, to build the original Dome Mine), and Campbell Red Lake Mines Ltd. of Toronto (founded in Ontario in 1944).
Placer Dome was heavily invested in mines in South Africa prior to the end of apartheid. Sensing that their ability to continue owning mines in post-apartheid South Africa would diminish, they started investing in Australia and Papua New Guinea, and briefly became Australia's biggest landlord.
Placer Dome operated the Detour Lake gold mine before selling the property in 1988 while it was being decommissioned. Placer Dome acquired several mining companies over its lifetime: Kiena Gold Mines Ltd. in 1988 (0.92 shares of Placer Dome Inc. for each share of Kiena Gold Mines Ltd.), Sigma Gold Mines Ltd. in 1988 (0.97 shares of Placer Dome Inc. for each share of Sigma Gold Mines Ltd.), Placer Pacific Ltd. in 1997 (0.066 shares of Placer Dome Inc. for each share of Placer Pacific Ltd. held), Getchell Gold Corporation in 1999 (2.45 shares of Placer Dome Inc. for each common share of Getchell Gold Corporation held), AurionGold Ltd. in 2003 (17.5 shares of Placer Dome Inc. for every 100 AurionGold shares, plus US$0.28 per AurionGold share), and East African Gold Mines Ltd. in 2003 ($252.4 million in cash).
In 2002 the first 3.6 tonne, 17 kW, hydrogen-powered hydrail mining locomotive for Placer Dome was demonstrated in Val-d'Or, Quebec.
