GREATLY UNDERVALUED
Sample 2 contained 45 diamonds greater than 2 carats, including 21 stones greater than 3 carats, 6 stones greater than 5 carats and 2 stones greater than 10 carats. The average size of the stones recovered from the sample is 0.21 carats per stone and the five largest diamonds recovered are 10.86, 10.55, 9.38, 8.53 and 6.38 carats. Three large diamonds were broken during processing of the kimberlite sample. The total weight of the matched pieces recovered from each of the three broken stones is 18.41 carats (28 pieces), 13.58 carats (5 pieces) and 11.66 carats (2 pieces).
Sample 2 was excavated from a trench on the southern lobe of the pipe, at a depth of approximately 5.5 metres below surface, and 1.5 metres below the level of the first bulk sample, the results of which were reported on September 8, 2010. Combined, Sample 1 and Sample 2 produced 4,786 diamonds with a total weight of 1,014.62 carats from 4,158.2 dry tonnes of kimberlite, resulting in an average recovered grade of 24.4 cpht, maintaining an average stone size of 0.21 carats per stone. The combined results of Sample 1 and Sample 2 are as follows:
