One size doesn't fit all

摘要

Operations at the Gunnar uranium mine in northern Saskatchewan stopped abruptly in 1964 with little to no decommissioning. The miners simply stopped work and walked away. Over the previous decade, the open pit and underground workings yielded tonnes of uranium ore that was refined on site and shipped to the United States. When the workers abandoned the site, they left behind an open pit over 100 metres deep, the mill, two acid plants and uranium processing buildings, and over six million tonnes of tailings and waste rock, as well as dozens of portals to underground workings.
