Joint news release: Oxfam Australia, Mineral Policy Institute and MiningWatch Canada

Australian, Canadian, and US mining companies that persist in dumping billions of tonnes of toxic heavy metals such as mercury and lead into the rivers and oceans of some of the world's poorest countries are causing irreversible environmental damage as well as driving human poverty. This warning came from a coalition of human rights groups and mining watchdogs as mining ministers from the Asia-Pacific region gather in Perth this week for a summit.

The geochemistry of the Tapian ore body is such that acid drainage and metal leaching from exposed tailings, such as those in the causeway, must be expected. The sulphide mineral nature of the Tapian ore body, which is linked to acid drainage and metal leaching is well documented.

"The principal sulphide copper mineral is chalcopyrite. (...) Pyrite [iron sulphide] is intimately associated with the chalcopyrite..."

Four years after a massive spill at Placer Dome's Marcopper mine put some 4 million tons of tailings into the 26-kilometre long Boac river on the island of Marinduque in the Philippines Placer Dome remains uncertain about when the cleanup will be completed and about what the final costs will be. The reason Placer Dome faces ever rising expenses and cannot finalize the cleanup of the Boac River is because the company refuses to respond to persistent opposition in the Philippines to the company's plan to place the spilled tailings in the sea.
