"The Ellendale mining lease area covers 123.9km². The current mine plan for Ellendale is up to 2015, but strong exploration potential is likely to extend the life of the mine significantly."

"Ellendale produces around half of the world’s rare yellow diamonds. The mine has life-of-mine off-take agreements with Tiffany & Co with regard to its production of yellow diamonds. A total of 78.88cts of Ellendale diamonds were sold for $57.6m during January-June 2012. Yellow diamonds accounted for just 15% of the total production but contributed 80% to the revenue."

"The E4 pipe, which was operated until 2009, is currently under care and maintenance. It has been identified with additional diamond resources. It is estimated that approximately 1.2mt of high-grade ore is still left on the ROM pad with 1mt of additional ore exposed in the pit, while 1.8mt of diamond ore is accessible via a cut-back. The E4 Satellite pipe towards the east of main E4 contains an inferred resource of 15.3mt."
