Billionaire Gina Rinehart is expanding her payroll to ramp up production from the Roy Hill Holdings mine in Western Australia's remote Pilbara outback. Many of her new employees get paid less because they have little or no mining experience, such as Courtney Grove, 24, who studied animal health and science at university.
