Mothae Project Phase 2 Sampling Yields 277 Carats

15 january 2009

The processing of 7,781 dry tons from Lucara Diamond Corp. and partner Motapa Diamonds Inc.'s Phase 2 of the Mothae bulk sample project in Lesotho yielded 642 diamonds for a total of 277.13 carats and a preliminary sample grade of 3.56 carats per hundred tons (cpht). Sample C3A produced fifteen stones greater than 2 carats and four stones greater than 5 carats, Tacy reported. The average stone size for the sample is 0.43 carats per stone and the largest three diamonds recovered are 22.71, 20.04, and 10.03 carats.
A revised dry tonnage of 8,192 for C2C yielded 355.74 carats, resulting in a grade of 4.34 cpht, a 16 percent increase relative to the previously reported value of 3.74 cpht. The sampling for the C kimberlite domain of the Mothae pipe, which makes up the largest part of the surface area of the pipe has now been completed.
"Sample grade and stone size distribution for Mothae continue to exceed the expectations that we had at the initiation of this bulk sampling program. With the C kimberlite domain delivering a sample grade well above historic results, we are increasingly positive about the economic viability of the Mothae kimberlite," says Dr. Larry Ott, Chief Executive Officer of Motapa.
A combined valuation, carried out in December by Shlomo Tidhar of Galaxy Diamond Expertise SA, on a parcel of 1,088 carats as a follow up to Galaxy's July 2008 assessment of the first 585 carats recovered in the bulk sampling program, yielded an average price of US$441 per carat.
