Ellendale discovery provides hope for the Australian diamond industry as Argyle closure looms

India Bore Diamond Holdings, a junior explorer, recently revealed a significant find of rare diamonds in a large alluvial deposit near Derby.

Once responsible for half the world's supply of fancy yellows, this site has been under exploration since May. The Ellendale lease, previously mothballed, was reopened for exploration following an expression of interest process initiated by the State Government in 2019, inviting companies to apply for tenements.

India Bore had been conducting drilling and bulk sampling in an adjacent diamond field, where they successfully recovered commercial diamond grades evaluated by prominent Antwerp-based diamantaires. The company focuses on the ancient buried river system, the L-Channel, formed approximately 22 million years ago. The L-Channel is estimated to contain at least 1.3 million carats of gem-quality diamonds. This discovery brings hope for revitalizing the Australian diamond industry as it seeks new sources following the closure of the Argyle mine.

The WA Government has spent about $230,000 on rehabilitating the Ellendale mining lease and preparing it for new operations.

The previous operator Kimberley Diamond Company went into administration in 2015 and relinquished its lease and environmental liabilities — reportedly up to $40 million — back to the State Government.

Mines and Petroleum Minister Bill Johnston was optimistic that renewed investment in the Ellendale operation could help rejuvenate the Kimberley diamond industry.
