Argyle Diamond Mine Operations Wind Down
“Fifty years ago, there were very few people who believed there were diamonds in Australia — even fewer could have foreseen how the Argyle story would unfold,” Rio Tinto Chief Executive of Copper and Diamonds Arnaud Soirat said. “To arrive at this final chapter has required vision, courage and determination to overcome significant challenges to enter new territory in diamond exploration, mining and marketing. “Today, Argyle’s influence stretches into many spheres and over many continents and I am very proud to acknowledge all those people who have contributed to the discovery and development of the mine and the production of some of the finest diamonds the world has ever seen.”
The Argyle ore body, a single pipe known as AK1, was discovered in October 1979. Alluvial operations began in 1983, open-pit mining began in 1985, and the mine became a fully underground operation in 2013. Over this period of time, the mine has produced more than 865 million carats of rough diamonds, becoming the world’s largest producer of colored diamonds and virtually the sole source of a very small but consistent source of rare pink diamonds.
“This is an historic day for the Argyle mine and the east Kimberley region and a great source of pride for this unique Australian success story,” Argyle Mine General Manager Andrew Wilson said. “A new chapter will now begin as we start the process of respectfully closing the Argyle mine and rehabilitating the land, to be handed back to its traditional custodians.”
