9/24/2009· The Olympic Dam/Roxby Downs mine has a voracious appetite for water to process the uranium, copper, gold and silver it extracts from underground. It obtains this water from the Great Artesian Basin (GAB) within the Lake Eyre region via two principal borefields, known as Borefield A and Borefield B (sometimes called "Wellfield"). These borefields have []
