      -  Three JO diamond sales of 9,224 carats completed in the quarter
         generating total revenue of US$1,919,676 (70% (DFI): 30% (Bonaparte)

         implementation in second half of 2007.
    

    Mining Activities

    The DFI/Bonaparte JO marine diamond mining operation off Luderitz,
Namibia continued throughout the quarter with strong results, and has now been
operating for a total of 5 months since commencement in late January 2007.
    JO diamond production of 8,279 carats for the June 2007 quarter
represents an increase of 78% over production achieved in the previous
quarter. During both April and May, successive monthly record productions were
achieved, driven by the full availability of the dual airlift mining system
which was established at the end of March 2007. Production for April reached
3,189 carats and in May reached 3,529 carats. In June the production declined
due to poor seasonal (winter) weather conditions and resultant technical
problems affecting operations. For part of this month only one airlift could
be operated. During the September 2007 quarter operational improvements are
again anticipated as a result of improving weather and the ongoing replacement
and repair of key pieces of equipment.
    JO mining results continue to meet expectations from the resource, and as
a result large stones have been regularly recovered with diamonds in excess of
2.0 carats occurring regularly. The largest diamond recovered to date, was a
9.2 carat diamond. Fancy colored diamonds are also recovered occasionally. The
diamonds recovered to date continue to be of approximately 95% gem quality.

    
    Diamond production is summarized in Table 1 below.

    -------------------------------------------------------------------------
    

    The total production from JO mining at June 30, 2007 stands at 28,477
diamonds weighing 12,318 carats with average stone size of 0.43 carats per
stone and representing an effective 5 months mining since commencement at end
January 2007. Mining to date continues to show that the mineralization and
economic grades extend in places beyond the resource boundaries defined by the
sampling data.
    Mining is presently taking place in the Diaz Prospect 1 JO mining area in
mining license ML111, under the terms of the formal mining agreement which was
announced on February 20, 2007. The agreement provides for a minimum of
6 months mining in the DP1 JO area, which has since been extended for up to
12 months by mutual agreement. The JO mining operations are being conducted by
DFI utilizing its vessel MV DF Discoverer on a 70% (DFI): 30% (Bonaparte)
shared revenue and agreed operating cost basis. Mining is currently in
progress in the 315,000m2 area within DP1 incorporating a 63,000 carat
Indicated Resource (National Instrument 43-101 compliant), identified in late
2006.
    Based on the success of the initial JO operations, discussions to extend
both the minimum mining term in the JO area, as well as expansion of the scope
of the JO have been concluded.
    The JO partners have now signed an amendment to the JO Mining Agreement
(announced July 16, 2007), whereby the original 1.6 km2 JO area in the Diaz
Reef Prospect of ML111 license offshore Luderitz, has been expanded to a total
prospective area of 10.8 km2. This area will be sampled by Bonaparte at its
cost, with the objective of substantially expanding the mining resources
available to the JO mining operations. In addition, Bonaparte's interest in
the expanded JO area has increased to 35%, where DFI is the mining operator
(i.e. gross revenue and agreed operating cost will be shared on the basis of
65% DFI, and 35% Bonaparte). The amendment to the agreement also requires
Bonaparte to fund an amount of not less than Namibian$5,000,000 directly on
resource development within the expanded JO area in ML111 over a period of
2 years from the effective date of this agreement.
    Sampling in the expanded JO area is expected to commence within the next
2-3 months, subject to availability of a suitable vessel. The delineation of
substantially larger JO mining resources in 2007 and 2008 is expected to
provide a basis for increased production, and may also allow consideration for
introducing a second mining vessel, at an appropriate stage.

    Sales

    During the quarter ended June 30, 2007, three sales of JO production were
completed in Antwerp, Belgium via DFI's existing sales agreement with Diamond
Tenders (Belgium) NV. The three sales comprised a total of 9,224 carats
(increase of 258% over previous quarter) realizing US$1,919,676 (250% increase
over previous quarter). To date, a total of four JO diamond production sales
have been completed at an average value per carat sold of US$214. The average
value per carat realized for the June quarter was US$208. Sales results are
summarized in Table 2 below.
