NUNAVUT – TAHERA DIAMOND CORP. of Toronto has the results from this years bulk sampling program on the JD-03 kimberlite pipe, 7 km from the companys Jericho diamond mine. Diamonds weighing a total of 136.07 ct were recovered from 500 tonnes of material.

JD-03 is a typical group one (non-micaceous) kimberlite and is interpreted to be pyroclastic with intense serpentinization, according to Tahera. In addition, it contains numerous crustal xenoliths including limestone and granite. The goal of the 2007 bulk sample was to better understand the diamond distribution and grade, as previous results showed the potential for large diamonds. In 1997, a single 3.63-carat stone was recovered from a 10.53-tonne sample. The 2007 bulk sample results show an average sample grade of 0.27 carat per tonne, similar to previous grades recovered. In total, 3,746 diamonds larger than 0.85 mm were recovered from 495.1 dry tonnes of kimberlite.

Based on the grade and value results of the recent sample, no further work is planned on the JD-03 kimberlite at this time.
