The trial mining program at Mothae has been going very well and is expected to
be completed in the third quarter of 2012.  A total of 720,000 tonnes of
kimberlte is scheduled to be processed of which 430,000 tonnes has been
processed to date. 

A Preliminary Economic Assessment study was contracted to ADP  in October 2011
and is expected to be finalized in the fourth quarter of 2012.  The objective
of the study is to gain a further understanding of the economic potential of
the Mothae project and to define the capital expenditure and operating costs
for mine development to a pre-feasibility level.

A core drilling program of approximately 6,100 metres commenced in November
2011 and is anticipated to be completed in the second quarter of 2012.  The
objective of the drill program is to define the internal geology of the Mothae
kimberlite and extend the currently defined kimberlite volume from a depth of
200 metres to 320 metres.
