Vancouver, British Columbia, CANADA

December 6, 2011 (LUC – TSX, LUC – BSE, LUC – NASDAQ OMX First North) … Lucara
Diamond Corp. (“Lucara” or the “Company”) is pleased to announce a significant
increase in the average value of diamonds recovered from the AK6 mine in
Botswana.  In anticipation of production start-up from AK6 in 2012, the Company
commissioned an updated valuation of the AK6 diamonds recovered to date,
resulting in a 24% increase in overall modeled value to US $301 per carat at a
1.5 mm cut-off size*.  This is a significant jump from the 2010 valuation and
represents the strong growth in demand for the type and quality of diamonds
produced from AK6.

Lucara’s AK6 mine is slated for production start-up in the first quarter of
2012 and will immediately become a key diamond asset producing over 400,000
carats per year on an annualized basis.  The AK6 diamond kimberlite is an
extremely rare occurrence globally with the high quality of diamonds it hosts.


AK6 Project 2012 Guidance

  • Diamond production to commence in Q1 2012 with full ramp up achieved during
    Q2 2012
  • Total ore mined forecast at 1.9 million tonnes in 2012 achieving an
    annualized 2.5 million tonnes per year
  • Diamond sales forecast at 325,000 carats in 2012 achieving an annualized
    400,000 carats per year
  • Operating costs of $20 per tonne to be achieved by Q4 2012
  • Initial mine life of 15 years at 2.5 million tonnes per annum – 2012 to


As the project transitions to operations and to better reflect the significance
of the new mine, the AK6 Project will be renamed the Karowe Mine.   Lucara
engaged with local communities and schools in search for a meaningful name for
the operating mine.  In support of our strong community relations a great deal
of interest was shown and many suggestions were received.  The adjudication
committee comprising community members and mine management selected Karowe Mine
– Karowe means ”precious stone” in the local dialect.

On November 27, 2011  Lucara’s management was pleased to host its Board of
Directors in Botswana for a board meeting followed by a site visit to AK6
(Karowe).  The board conducted a progress review of the project and approved
Lucara’s 2012 budget. 

Mr. William Lamb, President and CEO of Lucara Diamond Corp., commented, “AK6
(Karowe) is a strategic project and will soon be our first operating mine. We
are fully committed to building one of the best new mines in the industry and
look forward to being a major employer and contributor to the local communities
in which we will work for many years to come.”
