Riverine Disposal of Mining Wastes in Porgera: Capitalist ...

The cultural significance of clean, flowing water for promoting health in people and the land is in direct contrast to the activities of the Porgera gold mine. Built in 1990, the Porgera mine is one of only four mines in the world that practice the riverine disposal of mining wastes (Vogt 2012). Every day, 17,000 metric tonnes of mining tailings and waste rock are dumped into two major tributaries of the Porgera River. The past 28 years of mining activities have resulted in two massive rock glaciers, each tens of millions of metric tonnes in size, moving slowly down the river valley, erasing gardens, homesteads and past sites of artisanal alluvial mining.
