The South Kalgoorlie Gold Mine is a gold mine located south-west of Kalgoorlie, Western Australia. The mine is sometimes also referred to as "South Kal Mines - New Celebration", being a merger of the former "New Celebration Gold Mine" and the "Jubilee Gold Mine", which were combined in 2002.
The Jubilee Gold Mine is now located south-west of Kalgoorlie.
The passage states the Jubilee Gold Mine no longer exists, since it was combined with the New Celebration Gold Mine in 2002, but it was south-west of Kalgoorlie, so including this fooled the model.
