Release: BDI Mining: Cempaka diamonds valued at US$285 / carat

LONDON - 4 April 2005 - BDI Mining Corp. (AIM-BMG) has been advised by WWW International Diamond Consultants Limited that the first production parcel of 3,285 carats of rough diamonds from the Company's Cempaka diamond mine in Indonesia has a market value of US$285 per carat.

This valuation reflects the current strength in the world market for rough diamonds and is 52 percent above the US$187 per carat sales price that the Company achieved at tender during 2002 for the 4,656 carats of diamonds recovered during bulk testing.

WWW International is an internationally recognised diamond consultancy and, with its partners Aboriginal Diamond Group through Diamonds International Canada (DICAN), is the independent diamond valuer to the Canadian Government.

"The average price of this parcel is well above world average prices and demonstrates the high quality of Indonesia's rough diamond production," said Richard Wake-Walker, a director of WWW International.

Lee K. Spencer, managing director of BDI, said: "The current premium in the value of the Cempaka diamonds has the potential to more than double operating margins at the mine and add an additional US$6,000,000 per annum to Cempaka cashflow."

However, management cautions that world diamond prices fluctuate and that future diamond sales may not always achieve this value. (end of release)
