Argyle Diamond Mine Delivers Final Production

The Argyle ore body, known as AK1, was discovered in October 1979, with alluvial operations starting in 1983, followed by open-cast mining in 1985, and the transition to an entirely underground operation in 2013. Over its operational span, the mine has produced over 865 million carats of rough diamonds, making it the world’s largest producer of coloured diamonds and a primary source of rare pink diamonds.

To mark the formal transition from an operational mine to the beginning of closure, an event was held at the mine, attended by Argyle employees and local stakeholders. The closure process is anticipated to take around five years, involving decommissioning, dismantling, and rehabilitation, followed by a monitoring period. Post the final mining and diamond production activities, Argyle will continue to employ a reduced workforce, contributing to the local economy.
