Diamond Fields International Ltd.

had strong production and sales

results for the quarter ended June 30, 2007, from marine diamond mining joint

operations (JO) with Bonaparte Diamond Mines NL.

Key points:

Total JO production for the June, 2007, quarter of 20,269 gem diamonds

weighing 8,279 carats at an average size of 0.43 carat per stone;

Three JO diamond sales of 9,224 carats completed in the quarter

generating total revenue of $1,919,676 (U.S.) (70 per cent for Diamond Fields and 30 per cent for Bonaparte

in revenue and operating costs split); Total JO sales to date of 10,567 carats sold for $2,266,018 (U.S.) at an

average value of $214 (U.S.) per carat;Amended JO agreement resulting in expansion of JO resource area to

10.1 square kilometres and increase in Bonaparte’s interest to a 35-per-cent share of

agreed cost and revenues when mining is undertaken with DFI’s vessel

MV DF Discoverer in expanded area; Marine sampling program in expanded JO area planned for

implementation in the 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 five months since commencement in late January, 2007.

JO diamond production of 8,279 carats for the June, 2007, quarter

represents an increase of 78 per cent 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 continuing 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

two carats occurring regularly. The largest diamond recovered to date was a

9.2-carat diamond. Fancy coloured diamonds are also recovered occasionally. The

diamonds recovered to date continue to have a gem quality of approximately 95 per cent.

Total production

(January to June, 2007) 30,134 12,922 0.43

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 carat per

stone and representing an effective five months mining since commencement at end of

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 licence ML111, under the terms of the formal mining agreement which was

announced in Stockwatch on Feb. 20, 2007. The agreement provides for a minimum of

six 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 using its vessel MV DF Discoverer on the basis shared revenue and agreed operating cost of 70 per cent DFI/30 per cent Bonaparte. Mining is currently in

progress in the 315,000-square-metre 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 in Stockwatch on July 16, 2007), whereby the original 1.6-square-kilometre JO area in the Diaz

reef prospect of ML111 licence, offshore Luderitz, has been expanded to a total

prospective area of 10.8 square kilometres. 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 per cent, where DFI is the mining operator

(that is, gross revenue and agreed operating cost will be shared on the basis of

65 per cent DFI and 35 per cent Bonaparte). The amendment to the agreement also requires

Bonaparte to finance an amount of not less than $5-million (Namibian) directly on

resource development within the expanded JO area in ML111 over a period of

two years from the effective date of this agreement.

Sampling in the expanded JO area is expected to commence within the next

two to three 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 per cent over previous quarter) realizing $1,919,676 (U.S.) (250-per-cent increase

over the previous quarter). To date, a total of four JO diamond production sales

have been completed at an average value per carat sold of $214 (U.S.). The average

value per carat realized for the June quarter was $208 (U.S.). Sales results are

summarized.
