As of 2001, reserves and resources in the open-pit mined area contain 220 million tonnes of 2.5 to 3.0 carat (500 to 600 mg) per tonne graded ore, sufficient to sustain current production rates until 2007.
Products: The Argyle diamond mine leads the world in volume production of diamond, averaging annual production of 35 million carats (7,000 kg), or about one third of global production of natural diamonds. Production peaked in 1994, when 42 million carats (8,400 kg) were produced. Of this quantity only 5% is considered gem-quality, with the rest being either near-gem quality or industrial grade; this is somewhat below world averages of about 20% of mined diamonds qualifying as gem-grade.
