Diamond Fields International Ltd. - Strong preliminary results from 2007 marine sampling programme in Namibia; diamond sales and production update

    CAPE TOWN, Dec. 7 /PRNewswire-FirstCall/ - Diamond Fields International
 Ltd. (DFI:TSX) ("DFI" or the "Company") is pleased to announce that
 preliminary results from the 2007 marine sampling programme undertaken by
 Bonaparte Diamond Mines NL ("Bonaparte") in the ML111 Joint Operations
 ("JO") area offshore Namibia, show a 68% increase in the number of samples
 with positive diamond recovery, compared to the previous year's programme.
 The number of positive samples in which more than one diamond was recovered
 (multiple diamond samples) also increased by 85% over the 2006 operations.
 The Company is also pleased to report improved production results in
 Namibia from its mining vessel MV DF Discoverer coming out of the winter
 months.
 
     2007 Sampling programme
 
     A total of 451 diamonds weighing approximately 160 carats were
 recovered from the 290 positive samples during the recently completed 2007
 JO sampling programme. The preliminary results are provided in the Table
 below and recoveries will be adjusted if necessary, after final processing
 of the samples at the onshore facility in Luderitz.

     The programme was undertaken at Bonaparte's expense using the De Beers
 owned dedicated diamond sampling vessel MV Douglas Bay on a sampling grid
 of approximately 50m by 40m with an average footprint size of approximately
 2.1m(2) per sample in sediments up to 4m thick. Gravel in the size range
 +1.5mm to -12mm was screened out for processing and diamond recovery. The
 design of the programme will enable estimation of Indicated Resources in
 terms of National Instrument 43-101.
 
     Mining of the 63,000 carats Indicated Resource defined in the 2006
 sampling programme in the original JO area has been ongoing since
 commencement in January 2007.
 
     DFI's President and CEO, Roger Daniel commented: "We are delighted with
 the strong results from the Bonaparte joint operations sampling operations
 which have identified seven new diamond deposits which will support joint
 mining operations through 2008/2009. We expect these newly defined areas
 will be incorporated in the JO production plans early in 2008 to increase
 current production levels. The recent sampling programme covered
 approximately 24% of the expanded JO area of 10.8 km(2) and we anticipate
 further increases to the mining resource base with future development work
 in this area."
 
     Diamond sales and October marine diamond production
 
     The sale of the latest parcel of 1,889 carats from the JO marine mining
 operations off Namibia resulted in gross revenue of US$388,303 at an
 average price of US$205.55/carat. Total JO sales for production up to
 October 21, 2007 amounts to 17,455 carats sold for US$3,799,772 in total
 revenue at an average price of US$217.69/carat.
 
     Coming out of the winter months, diamond production continued to
 improve in October 2007 with recovery of 4,864 diamonds weighing 1,894
 carats. Production in September 2007 was 1,618 carats. Total production
 from the JO area to October 31, 2007 is 42,827 diamonds weighing 18,139
 carats at an average size of 0.42 carats/stone.
