Possible discovery of new colored diamonds at the Ellendale mine
India Bore Diamond Holdings (IBDH), one of two Australian companies currently operating at the Ellendale site in Western Australia, has confirmed two distinct layers of diamondiferous gravel deposits at its site.
A variety of colorless, yellow and brown gem-quality diamonds have been found in the upper A-layer and deeper B-layer gravel deposits weighing between 0.41 and 0.66 carats. The discovery was made after evaluating a small volume of gravel samples for this year’s mining season.
Last year an extremely rare ‘double diamond’ was also discovered and is expected to boost diamond production at the mine.
The 0.85 carat diamond which had a smaller stone enclosed in a cavity inside the stone was unearthed about 200 kilometers below the surface in the same alluvial deposit.
In 2020, IBDH also unearthed unique yellow diamonds with rare purple fluorescence in the same area.
IBDH is one of the few mining companies trying to increase production of colored diamonds to meet growing global demand amid supply shortages following the closure of Argyle Mine, which was the largest source colored diamonds, especially pink diamonds.
In early 2021, IBDH obtained its 21-year mining lease for the L-Channel deposit covering approximately 2,300 hectares.
The Ellendale Diamond Field is estimated to contain at least 1.3 million carats of gem-quality diamonds, including fancy yellow diamonds. IBDH is one of two companies – the other being Burgundy Diamond Mines – currently exploring for diamond deposits in the area, located around 135km east of Derby in the West Kimberley.
Opened in 1976, the Ellendale mine was at one time the world’s largest producer of fancy yellow diamonds and had an exclusive supply agreement with Tiffany & Co.
However, it ceased production in 2015 when former owner Kimberley Diamond Company went into liquidation.
