Oct 19, 2009 (A Wilson) - The discovery of a second, new kimberlite, the U2 kimberlite, was announced in January 2007. This kimberlite has a geophysical surface area of approximately 7 ha and was intersected at a depth of approximately 17 m The kimberlite is described as green in colour and weakly altered breccia. It contains limestone xenoliths and some granite xenoliths. Olivine macrocrysts are moderately serpentinized. The U2 kimberlite has an estimated surface area of 7 ha.

Feb 03, 2011 (A Wilson) - A 87.88 kg sample of kimberlite was processed from a single drill hole, 2 microdiamonds were recovered. Within this sample, 67 Group I eclogitic garnets, 20 cpx, 16 ol, 9 opx, 5 chromites and 3 peridotitic G10 garnets were recovered, with compositions analogous to those found in the diamond inclusion field. A total of 54 diamonds were recovered from 1700.6 kg of core drilled from the pipe. A total of 226 commercial sized diamonds were recovered from the first 11 reverse circulation drill holes completed in 2010. Approximately 42% of the sones are white. A grade of approximately 18.1 cpht was returned below 90 m depth.
